00:00:11.207" data-end="00:00:16.017">Lift off of NASA's Artemis 1 mega-rocket launching Orion to the Moon.
00:00:25.017">0:17">The first CubeSat to visit the Moon arrives in lunar orbit, 0:21">and a solar snake slithers across the face of the Sun.
[0:26] 00:00:55.457">All that and more coming up on Space Time. 0:50">The world's most powerful rocket, NASA's Space Launch System, or SLS, has successfully.
[0:33] 0:49" data-start="00:00:33.200" data-end="00:00:48.560">Music.
[0:55] 00:00:55.457" data-end="00:00:58.073">Blasted into orbit on its maiden flight.
00:01:11.297">0:59">The spectacular night-time launch from Pad 39B at the Kennedy Space Center in Florida 1:04">carried the Artemis 1 Orion spacecraft on the first leg of a journey that will ultimately 1:09">return humans to the Moon.
00:01:12.017" data-end="00:01:24.405">Meteorologists with the United States Space Force's Space Launch Delta 45 team, which 1:17">which operates Space Launch Complex 39B at Cape Canaveral, 1:21">forecast 80% favorable weather conditions for the flight.
[1:25] 00:01:25.177" data-end="00:01:35.739">The Space Launch System rocket and its Orion spacecraft 1:28">arrived at Kennedy's Pad 39B on November 4th, 1:32">where they remained in place, riding out Hurricane Nicole.
00:01:36.497" data-end="00:01:47.537">Following the storm, teams conducted thorough assessments 1:39">of the rocket, spacecraft and associated ground systems 1:43">and confirmed there were no significant impacts 1:45">the severe weather event.
00:01:54.643">1:48">Engineers had previously rolled the giant 98-meter tall rocket back into the Vehicle 1:52">Assembly Building on September 26.
00:01:55.297" data-end="00:02:15.241">That was ahead of Hurricane Ian and after scrubbing two earlier launch attempts, one 2:00">on August 29 due to a faulty temperature sensor on one of the SLS core stage's RS-25 main 2:06">engines and a second on September 4 due to a liquid hydrogen propellant leak in an interface 2:12">between the Space Launch System rocket and the mobile launcher.
00:02:25.530">2:16">Prior to rolling back the 6.5 km to the Vehicle Assembly Building, 2:20">teams successfully repaired the cryogenic hydrogen leak 2:23">and developed updated tanking procedures.
00:02:26.097" data-end="00:02:37.773">While in the Vehicle Assembly Building, 2:28">engineers performed standard maintenance to repair minor damage 2:31">to the foam and cork on the thermal protection system 2:34">system and to recharge or replace batteries throughout the launch vehicle.
[2:39] 00:02:38.583" data-end="00:02:49.073">Artemis 1 had a two-hour launch window for its 26-day flight into orbit around the moon and back. 2:44">The textbook perfect launch was the first leg of a mission, which will see Orion travel thousands
00:02:59.505">of kilometers beyond the moon before returning to Earth. And launch director NTD, our launch team is 2:55">ready to proceed at this time. I copy all NTD. At this time I will proceed with my poll. And,
00:03:06.571">3:00">attention on 232, this is the launch director performing the final poll for launch. Verify no 3:05">No constraints and go for launch.
00:03:17.023">3:07">EGS Program Chief Engineer. 3:09">EGS Program Chief Engineer verifies that the EGS SLS and 3:12">Arroyum Program Chief Engineers have no constraints and are 3:15">go for launch. 3:16">Copy, Greg.
00:03:18.869">Thank you. EGS Chief Safety Officer.
00:03:19.153" data-end="00:03:26.349">The EGS CSO verifies the SLS Orion and EGS CSOs have no 3:24">constraints and are go for launch.
00:03:34.560">3:27">Copy, John. 3:28">Thank you. 3:29">Range weather. 3:30">Weather has no constraints and weather is go for launch. 3:32">Copy LWO and Mission Manager, Launch Director.
00:03:41.806">3:35">Launch Director, Mission Manager 232, the Mission Management team has been pulled. 3:39">You have a go to proceed with terminal count and launch of Artemis 1.
00:03:45.020">3:42">I copy y'all, thank you. 3:44">And entity, Launch Director.
[3:45] 00:03:45.497" data-end="00:03:56.853">3:46">Go ahead, Launch Director. 3:47">Yes, sir. On behalf of all the men and women across our great nation who have worked to bring this hardware together to make this day possible, 3:54">and for the Artemis generation, this is for you.
00:04:01.413">3:57">At this time, I give you a go to resume count and launch Artemis 1.
00:04:02.692">Copy, Launch Director, and thank you.
00:04:02.836" data-end="00:04:07.787">4:03">All right, we do have a couple of steps to configure, 4:05">and then we will be ready to resume the clock. 4:06">CVSC, NTD.
00:04:08.093" data-end="00:04:12.072">CVSC here. 4:09">Initiate recording of Orion cameras at this time. In work.
00:04:12.369" data-end="00:04:16.591">R, NTD. 4:13">RSR here. 4:14">Perform the booster ignition, 4:15">SNA arm rotation enable.
00:04:21.020">4:17">NDT, RSR, booster ignition, 4:19">SNA arm rotation enable is complete.
00:04:27.961">And I copy, thank you. 4:22">Okay, so there you heard the poll from Launch Director, 4:26">getting ready to get that new T-Zero time.
00:04:28.312" data-end="00:04:34.254">The poll that you heard was the NASA test director's poll. 4:32">All right, and we have verified no cutouts at this time.
00:04:42.635">4:35">And all personnel, we are going to resume the clock. 4:37">GLS, you can resume the clock on your mark. 4:39">GLS copies. 4:40">Countdown clock will resume on my mark. three.
[4:43] 00:04:43.373" data-end="00:04:52.023">2, 1, mark. GLS mainline has been initiated. 4:48">Okay, we went straight into terminal count. Control has been given over to,
00:05:06.103">the GLS, the ground launch sequencer, a computer and software that is doing 4:57">all of the commanding and monitoring of the space launch system. We'll hear 5:00">call-outs from the GLS operator Alex Pandelos, as well as NASA test director Jeff Spalding.
00:05:10.740">GLS is pre-tensioning the umbilicals at this very moment. That's getting them ready to detach.
00:05:11.055" data-end="00:05:23.253">At liftoff, those arms will swing away, let go of the rocket in a clockwise direction. 5:16">The GLS is performing up to 100 commands per second, including configuring ground systems for power transfer to the rocket.
00:05:34.812">GLS is turning on cameras, recording video inside and outside the crew module to collect data for engineers. 5:29">Purging the afskurt booster with high flow nitrogen, clear out any hydrogen gas that may be there.
00:05:36.594">5:35">The crew access arm is already retracted.
00:05:40.636">5:37">When there is crew during Artemis II, it would happen at T-6 minutes.
00:05:41.086" data-end="00:05:49.903">The base of the mobile launcher, if something wasn't done to reduce the power from the pressure 5:46">caused by the rocket's ignition and thunderous sound, it could damage the rocket.
[5:51] 00:05:50.674" data-end="00:05:57.399">So the ignition overpressure and sound suppression system will flood the mobile launcher with water. 5:55">That sequence starts at T-17 seconds.
00:06:05.753">5:58">Now coming up in less than 30 seconds, the ground launch sequencer will start bringing the high energy systems online, 6:04">starting with core stage pressurization.
00:06:10.173">6:06">Fire in room one is completely silent 6:09">as they listen for the next call. GLS.
[6:11] 00:06:11.334" data-end="00:06:20.381">Core Stage tank pressurization. 6:13">The Core Stage tank is now pressuring, pressurizing to flight levels. 6:17">The replenish valve to the liquid hydrogen tank now closing.
00:06:22.596">6:21">The liquid oxygen tank will come a little later.
00:06:30.446">6:23">Now we're arming the Orion Ascent Pyros and transfer to internal power. 6:27">The launch abort system or LAS jettison motor is now armed.
00:06:33.876">6:31">On this flight the abort motor is inactive because there is no crew on board.
00:06:34.488" data-end="00:06:41.456">Up next is the flight termination system or FTS which gives the Space Force the ability 6:39">to destruct the rocket if it goes in the wrong direction.
00:06:42.923">Let's listen in for that. 6:43">GLS is go for FTS arm.
[6:44] 00:06:44.417" data-end="00:06:50.278">The flight termination system is now armed. 6:47">This is where the RS-25 engines and their bleed go to high flow.
00:06:53.996">6:51">It's been a little tricky to dial in. 6:52">GLS is go for LH-2 high flow bleed check.
[6:55] 00:06:54.934" data-end="00:07:02.647">Good word, we've passed that. 6:56">The cryo team got the LH-2 engine bleed pressure loop dialed in. 7:01">They are now at the right temperature for launch.
00:07:03.115" data-end="00:07:04.033">Countdown continues.
00:07:16.420">7:05">Up next, GLS fires up the capos. 7:07">Those are high-speed turbines which provide pressure to hydraulic pumps that steer the RS-25s. 7:12">Stands for Core Stage Auxiliary Power Unit, START. 7:14">GLS' GO for Core Stage APU, START.
00:07:20.507">7:17">That now leads to the thrust vector control test.
00:07:21.138" data-end="00:07:25.666">That can proceed now. 7:22">The engines gimbal at the bottom of the core stage. You will hear the GO for purge sequence four.
[7:28] 00:07:27.502" data-end="00:07:34.245">That's a helium purge of the four core stage engines downstream of the propellant valve, 7:33">getting the air and moisture out.
[7:35] 00:07:35.316" data-end="00:07:36.072">GLS is go for prep sequence four.
[7:38] 00:07:37.999" data-end="00:07:48.712">And in just a few seconds GLS will close the core stage LOX vent liquid oxygen. 7:43">The white vapor cloud caused by the super cold gaseous oxygen condensing the water in the atmosphere will disappear.
00:07:54.365">7:49">And there it goes, it's closed. LOX vent closed. Pressure rising in the core stage LOX tank to flight levels.
[7:55] 00:07:55.130" data-end="00:07:57.614">Engines will gamble before core stage.
[7:59] 00:07:58.560" data-end="00:08:11.530">RS-25 engines, gimbling around, testing the ability to steer the rocket into space. 8:05">They will operate at 109 percent performance. Each RS-25 throwing down a half million pounds of,
00:08:17.834">8:12">thrust. All four, two million pounds. All together with the boosters, 8.8 million pounds of thrust.
00:08:18.104" data-end="00:08:20.346">GLS is going for upper stage to internal power.
00:08:31.877">8:21">Now the upper stage has gone to internal power. So power is removed from the rocket's upper stage, 8:26">the ICPS and it's been switched to battery power. The same milestone is coming up for the core stage,
00:08:32.472" data-end="00:08:50.098">at T minus one minute and 30 seconds. GLS scope for core stage to internal power. The rocket's core 8:39">stage which houses the three flight computers is now on battery power so there is no more hold time 8:45">available because there's no more margin on the battery so if we have a hold we'd have to.
[8:51] 00:08:51.034" data-end="00:09:03.170">To recycle back to T-minus 10 minutes and recharge those batteries. The count 8:55">continues. A note now, shortly after liftoff, mission control Houston will take 8:59">control of the rocket. Coming up at T-minus 33 seconds, the GLS will hand,
00:09:07.570">off control to the ALS. This is the autonomous launch sequencer. On board the.
[9:09] 00:09:08.886" data-end="00:09:15.610">Rocket it will take over command and control of the rocket, but the ALS will 9:12">check, make sure there's no holds coming from the ground up until T-minus.
00:09:24.082">9:16">GLS is go for ALS. And we are go for ALS. The space launch system is now 9:20">Now counting down to liftoff of Orion on its maiden voyage to the moon.
00:09:28.538">Launch team can no longer recycle the count. 9:26">Sound suppressor water now flowing under the ML.
00:09:29.474">Here we go.
[9:31] 00:09:30.779" data-end="00:09:40.601">Hydrogen burn-off igniters initiated. 9:33">Seven, six, five, four stage engines start. 9:38">Three, two, one, boosters in ignition.
00:09:41.109" data-end="00:09:41.627">And liftoff of Artemis I.
[9:43] 00:09:43.382" data-end="00:09:46.884">We rise together back to the moon and beyond.
[9:54] 00:09:54.229" data-end="00:10:03.269">All four RS-25 engines on the core stage 9:57">and two solid rocket boosters 9:58">now propelling the vehicle at 128 miles per hour. Good control on the roll from teams in Mission
00:10:13.189">Control Houston, all good calls so far. Now 30 seconds into the flight of Artemis 1. First 10:09">mile done will be for the vehicles to pass through Max Q in about one minute and nine seconds into
00:10:25.989">launch. This is the greatest period of atmospheric force on the rocket. SLS now traveling 607 miles 10:20">per hour. An 8.8 million pounds of maximum thrust quiet here in the loops in Mission Control.
00:10:34.989">10:26">Four core stage engines are throttling down ahead of passing through Max Q. 10:30">Now one minute, 21 seconds into the flight, traveling at 1,420 miles per hour.
[10:37] 00:10:36.989" data-end="00:10:39.989">The four core stage engines are back at maximum thrust.
[10:43] 00:10:42.989" data-end="00:10:51.773">The next major milestone will be for the solid rocket boosters to cut off in Jettison 10:47">about two minutes and 11 seconds into the flight, so about 30 seconds from now.
00:10:57.939">10:52">Again, quiet here in Mission Control Houston as teams continue monitoring the flight of Artemis 1.
00:10:58.229" data-end="00:11:06.068">We're now 16 miles downrange from the launch pad at Kennedy Space Center traveling over 11:02">2,800 miles per hour. 11:04">Standing by for solid rocket booster Jettison.
00:11:21.829">11:07">Confirmation that the solid rocket boosters have separated these 177 foot boosters. 11:12">Now the core stage continues to power the flight of Orion all four RS-25 engines firing 11:17">traveling over 3,400 miles per hour, 46 miles downrange.
00:11:22.119" data-end="00:11:29.649">Hearing nominal calls here in Mission Control Houston. We've still got four good engines on the core stage. 11:27">Next up we'll be looking for the service module fairing to separate.
00:11:41.789">11:30">This is three 15 by 15 foot fairing panels providing structural support protecting the service module. 11:35">Those will separate at about three minutes and 11 seconds into flight and very shortly thereafter will be followed by the launch abort system,
00:11:45.909">11:42">separation. Just over three minutes into the flight of Artemis 1 now traveling over.
[11:47] 00:11:46.529" data-end="00:11:49.169">4,060 miles per hour, 83 miles downrange.
00:11:57.409">We just had confirmation that the service module fairing has separated and that the launch abort system pyros have fired 11:55">separating those from Orion as well.
00:12:06.569">We just heard the call for three engine press meaning if SLS were to lose an engine at this point in the mission we could still 12:03">achieve a nominal mission. We would just have an extended main engine cutoff time.
00:12:16.466">12:07">However, we still have four good engines all at maximum thrust right now powering the first flight of Artemis at 12:13">5200 miles per hour, 12:15">148 miles downrange.
00:12:22.849">12:17">We're four minutes and 16 seconds into the flight of Artemis 1. So far we've had a clean ascent.
[12:23] 00:12:23.254" data-end="00:12:36.749">We saw those solid rocket boosters jettison about two minutes and 11 seconds after liftoff. Shortly after we had the service module fairings 12:30">separate as well as the launch abort system. The launch abort system was inert for this flight except to perform this separation.
00:12:48.389">12:37">Those four core stage engines will continue to fire and power the flight of Artemis 1, now traveling over 12:43">6,800 miles per hour, 229 miles downrange. Booster flight controller,
00:13:00.069">12:49">reports that the engines are looking good. Our core stage main engine cutoff 12:52">time is about eight minutes and three seconds. We are now five minutes and 11 12:56">seconds into the flight, 7,656 miles per hour.
00:13:01.342" data-end="00:13:08.716">core stage engines, those four RS-25 engines. The last time those core stage 13:05">engines flew they were taking space shuttles to orbit and now with upgraded
00:13:22.156">13:09">capabilities they're launching the future of human spaceflight. Five minutes 13:12">42 seconds into the mission we are now traveling 8,800 miles per hour 345 miles 13:18">downrange from the launch pad at Kennedy Space Center. Again we are anticipating.
[13:22] 00:13:22.417" data-end="00:13:37.716">Core stage main engine call off at about eight minutes and three seconds and 13:26">about ten seconds later we'll see core stage separation at which point Orion 13:29">and the interim cryogenic propulsion stage will be flying free. Now traveling 13:33">over 10,000 miles per hour, 6 minutes and 15 seconds into the flight of Artemis 1,
00:13:46.076">13:38">427 miles downrange. Quiet here on the loops in Mission Control Houston, teams 13:43">continue to monitor this first flight. About a minute and a half now until that
00:13:53.636">core stage main engine cutoff time, our four core stage engines continue to fire 13:50">maximum thrust. Coming up on seven minutes since launch today, now traveling
00:14:04.076">13:54">over 12,800 miles per hour, 563 miles downrange. Again, still quiet here in the 13:59">in Mission Control Houston. As we prepare for main engine cutoff, the four RS-25
00:14:16.896">engines are beginning to throttle down. 30 seconds now until core stage main 14:08">engine cutoff. All four engines continue to throttle down. Now 7 minutes 45 14:13">seconds into the flight traveling over 16,000 miles per hour, continuing to hear.
[14:17] 00:14:17.150" data-end="00:14:24.516">Good calls here in Mission Control Houston. We're standing by for core stage 14:20">main engine cutoff. And we have confirmation of core stage main engine
00:14:35.076">14:25">cutoff Orion is now in Earth's orbit. The Flight Dynamics Officer reports that we have 14:30">a nominal main engine cutoff and we just heard the call for core stage separation. That means
00:14:54.501">Orion and the Inter-Aid cryogenic propulsion stage are now flying free from the core stage 14:39">of the space launch system. Artemis One mission manager Mike Sarafintz says space launch systems 14:45">accomplishment of the first major mulsner of the mission allowed Orion to embark on 14:49">the next phase, that is to test its systems and prepare for future manned missions.
[14:55] 00:14:55.041" data-end="00:15:08.112">Artemis 1 is a critical part of NASA's Moon to Mars exploration program. 15:00">That'll see humans establish a permanent lunar base and then use that as a launching 15:05">pad for eventual manned missions to Mars and beyond.
[15:09] 00:15:19.611">Artemis 1 is a shakedown cruise, testing the technology which will be used in 2024 15:14">on the manned Artemis 2 mission. That'll see humans return to lunar orbit for the first time
00:15:37.531">15:20">in over half a century. And that will be followed by the return of humans to the 15:24">lunar surface on Artemis 3 in 2025. NASA Administrator Bill Nelson says Artemis 1 15:32">is pushing Orion to the limits of deep spaceflight. Eight minutes and eight seconds after launch,
00:15:47.851">15:38">the Space Launch System core stage achieved MECA, or Main Engine Cutoff, 15:42">successfully shutting down its four RS-25 main engines, which first flew decades earlier on
00:15:59.131">15:48">space shuttles. Stage separation occurred 10 seconds later, with Orion and its interim 15:54">cryogenic propulsion upper stage achieving orbit insertion. After reaching its initial
00:16:09.851">orbit, Orion deployed its solar arrays and engineers began performing checkouts of the 16:04">spacecraft systems. After a single 90-minute orbit around the Earth, the SLS upper stage
00:16:25.991">16:10">successfully ignited for an 18-minute trans-lunar injection burn, placing Orion on course for 16:16">the moon and boosting its speed from 28,160 km per hour to 36,210 kph. Orion then successfully
00:16:33.706">16:26">jettisoned its upper stage and began its outward coast to the moon, powered by its European 16:31">Space Agency-built service module.
[16:35] 00:16:34.511" data-end="00:16:48.362">Over the following hours and days, a series of 10 small cubesats carrying a range of scientific 16:40">experiments and technology demonstrators were deployed from the upper stage's interstage 16:45">ring which connected the upper stage to the Orion spacecraft.
00:17:01.109">16:49">An 11th CubeSat will be deployed once near the Moon. 16:53">Each of these microwave oven-sized satellites has its own mission, 16:57">designed to help fill gaps in science's understanding of the local space environment,
00:17:05.880">the Moon, or to test technologies for future missions to explore the Moon and beyond.
00:17:06.501" data-end="00:17:12.668">Orion's service module also performed a series of course correction boons, 17:11">keeping the spacecraft on target.
00:17:13.280" data-end="00:17:22.693">Throughout the flight, mission managers at NASA's Johnson Space Center in Houston, 17:17">Texas are conducting ongoing checkouts to ensure all systems are nominal.
00:17:36.133">17:23">About now Orion is undertaking its flyby of the Moon, performing a close approach to the 17:28">lunar surface on its way to a distant retrograde orbit, a highly stable orbit 65,000 km beyond 17:35">the Moon.
00:17:52.073">Orion will spend about 10 days in lunar orbit before heading back to Earth at some 40,000 17:41">km per hour, eventually splashing down under parachutes in the North Pacific Ocean off 17:46">the coast of California. It'll be the fastest reentry ever of a human rated spacecraft.
[17:54] 00:17:53.727" data-end="00:18:03.353">Communications between Mission Control and Orion are being undertaken jointly by the 17:59">Near Space Network, which is managed by NASA's Goddard Space Flight Center in Greenbelt,
00:18:17.790">Maryland and which provides communications for spacecraft in low Earth orbit, and the Deep Space 18:09">Network, managed by NASA's Jet Propulsion Laboratory in Pasadena, California, which provides 18:14">longer-range communications and tracking beyond Earth orbit.
00:18:18.366" data-end="00:18:27.386">The Deep Space Network has three tracking and communication stations, 18:22">located at Goldstone, California, Madrid, Spain and at Tidbin, Billiard and Ecamberra.
00:18:46.291">18:28">The Deep Space Network, or DSN as insiders call it, is currently supporting dozens of missions 18:33">across the solar system and even beyond into interstellar space. It was the Deep Space Network's 18:39">Cambra station which was first to make contact with Orion as it left Earth's orbit on its outbound 18:45">journey to the Moon.
[18:47] 00:18:53.396">And Glenn Nagle from the Canberra station says it'll also be the last to make contact with 18:51">Orion as it returns home.
00:19:06.798">So both the near space network and the deep space network have been providing the two-way 18:59">communications to track NASA's Artemis mission on its journey since the time of its launch 19:03">and then right throughout its journey to the Moon and then return to Earth's flashdown.
00:19:07.140" data-end="00:19:13.370">So particularly for Canberra, we were the first station to have contacted the spacecraft 19:11">shortly after its launch from Cape Canaveral, Florida.
00:19:20.752">And then we handled communications, 19:15">and in fact, right throughout the following day, 19:18">to be able to make sure that spacecraft is on its journey,
00:19:30.789">19:21">a couple of the course corrections that it needed to do, 19:23">and have been providing back from the spacecraft 19:25">really spectacular images of a downward journey 19:28">leaving the Earth behind and the Moon getting closer in the window.
00:19:30.876" data-end="00:19:43.077">19:31">For those of us old enough to remember the Saturn V 19:34">and Apollo 11 and that whole era, 19:36">it does bring back memories. 19:38">Oh, it certainly does. I was that seven-year-old watching the Armstrong and Buzz Aldrin walking on the surface of the moon.
[19:44] 00:19:43.556" data-end="00:19:55.951">For me, having no idea, more than 50 years later, I'd be sitting at the place watching 19:49">a new spacecraft hitting off to the moon, getting ready to send humans back to the surface 19:54">of the moon. with a long white.
00:19:56.212" data-end="00:20:01.370">But yeah, it certainly brought back memories of those amazing days of Apollo. 20:00">This isn't just going back to the Moon.
00:20:07.502">20:02">This is setting humanity up for eventually going onto Mars because it'll be Orion that'll 20:06">be doing that.
00:20:13.631">20:08">Yeah. So this spacecraft is not just designed to travel through the Moon. 20:11">It is a vehicle to eventually take humans off to Mars.
[20:14] 00:20:26.142">But we need the Moon as a staging post, a place to live and work for longer periods 20:18">of time, building the infrastructure and the experience that we need to be able to take 20:22">that next great leap a thousand times further away than the moon to the planet Mars.
00:20:33.902">That may still be another 20 years or more away, we're not in the race anymore, but we 20:30">will go when we're ready and we'll be doing it with multiple nations together.
00:20:34.147" data-end="00:20:43.662">So the moon is a place where we can build a base of operations, a scientific base, just 20:38">like we have in places like Antarctica, many nations working together in science, cooperating and working there.
00:20:43.662" data-end="00:20:53.422">20:44">So we can do the same at the moon and use that and that experience to go further afield. 20:48">multinational approach is happening already with Orion, the service module was built by 20:52">the European Space Agency.
00:21:06.853">Yeah, so the Europeans are a big part of this mission and of course we're using some of 20:58">the best technologies to develop the spaceflight over the last 50 years in this new vehicle, 21:02">but with all new power systems to allow the spacecraft to stay out there for longer periods,
00:21:07.105" data-end="00:21:18.302">of time, going to be building a space station in orbit around the moon, Lunar Gateway, which 21:11">will take the cooperation of many, many nations, up to 15 nations in a similar way that we've 21:16">done with the International Space Station and Earth orbit.
00:21:26.142">The lunar gateway will probably form the basis of the eventual vehicle that goes to Mars. 21:24">Yes, so for building these larger structures and.
[21:27] 00:21:36.632">Essentially, particularly in deep space, that means you're not sort of tied down to 21:31">having to get your whole vehicle off the Earth. 21:33">You need an enormous rocket to launch something big enough to take a journey there.
00:21:48.081">21:37">So if we can do that construction in Earth orbit, basically put our spaceship together 21:40">as a station with pulsions and power modules and habitat, storage and all the things we 21:45">need to go on that journey, then yeah, a much better way to do it.
00:21:58.401">And even a vehicle that might not necessarily have that one use. 21:51">It could be a cycling vehicle just constantly traveling back and forth between Earth and 21:55">Mars and a big elliptical orbit and taking humans there for the ride.
00:22:11.921">Now that sounds a lot like Elon Musk in Starship. 22:01">Well yeah but we're at that time and technology we can do it. It was actually 22:04">a concept originally. He steamed up five stars Aldrin, second man to walk on the moon. A 22:09">great engineer came up with this idea for a Mars Cycler spacecraft.
00:22:13.761">22:12">And not a bad boxer either from what I hear.
[22:16] 00:22:15.601" data-end="00:22:23.841">Yeah sometimes he gets a little bit annoyed by the moon deniers shall we say. 22:20">Yeah how does Orion compare to the old Apollo capsules?
00:22:29.801">22:24">So we're looking with the Apollo program, we're able to send three astronauts on a fairly 22:28">cramped journey to the moon.
00:22:35.361">22:30">So you've got a sort of 50% larger spacecraft here with the largest peach seal we've ever 22:34">produced for human rated spacecraft.
00:22:42.841">We've got to carry up to four to perhaps six astronauts at a time on journeys to the moon. 22:41">So we just won't be landing two guys on the surface.
00:22:56.194">22:43">We'll be landing the first woman on the moon, the first people of color, other guys, a whole 22:48">crew to do really intense exploration and especially when we get to the point to build 22:52">scientific base somewhere near the South Pole. We're going to need more than just two people on,
00:23:06.361">22:57">the surface. And this is also where Elon Musk and Starship come back in because a version of 23:01">Starship to be called HLS will actually do the shuttling between what will be the Gateway,
00:23:21.321">23:07">Space Station and the lunar surface. Yes, so NASA has selected SpaceX out of three competitors to 23:12">better provide the human landing system HLS to take astronauts from Gateway down to the surface 23:17">of the moon. Now of course SpaceX hasn't had the first launch of their new vehicle.
00:23:28.017">Do that to even start testing that program but they're probably only a month away before 23:26">Will they actually do that first attempt?
[23:28] 00:23:28.206" data-end="00:23:38.456">Of that launch for that type of vehicle and behind the scenes, they are working on the human landing 23:34">system to be a very big vehicle. In fact, for me, I sure did. It's a lot like the types of vehicles.
[23:39] 00:23:48.776">That we had in science fiction movies of the 1950s, that great big cylindrical rocket and the big 23:44">landing legs and powerful motors that landed on the surface of the moon and take off again,
00:23:57.022">23:49">leaving nothing behind. But the big thing about a big vehicle landing on the moon is you can take 23:53">a lot of cargo with you. And that's going to be essential if we're going to explore further afield.
[23:57] 00:23:57.176" data-end="00:24:15.176">We need transport vehicles for the moon, we all need to take infrastructure, power system, 24:02">putting solar on the moon, having communication satellites in orbit around the moon just to relay 24:07">signals from one place to the other. So yeah, there's some exciting times ahead and it's 24:10">a combination of those government programs through NASA, the In-Space Agency and others,
00:24:18.856">and of course the private sector that can provide that additional investment.
00:24:35.327">24:19">And of course Artemis 1 was carrying a number of passengers, namely a whole bunch of CubeSats. 24:24">Yeah, so in the Eater stage after the spacecraft started its journey out to the moon, the Eater 24:29">stage had 11 CubeSats in it. So CubeSats are these small sort of almost microwave oven-sized,
00:24:46.296">compact spacecraft. They're usually solar powered and they sort of unfurl themselves and start their 24:41">own journey. So you've got missions from Japan and from NASA is sending some little miniature
00:24:55.136">spacecraft and a few other private companies as well to do explorations like look at new landing 24:52">systems for heading down to the surface of the Moon with tiny spacecraft or
00:25:11.456">spacecraft to look for water ice on the surface of the Moon or to even go off 25:00">and do biomedical experiments as one called biospensinal which is actually 25:04">carrying on board samples of DNA and human tissue so we can see what the 25:07">long-term effects of the lunar radiation environment so far away from the Earth's.
[25:12] 00:25:12.038" data-end="00:25:21.212">Magnetic field, what that will be on the human body and that will be really 25:15">important for when we're sending humans and having them working on the Moon for 25:18">long periods of time. What do we need to do to protect those astronauts?
00:25:25.911">That's Glenn Nagle from NASA's Deep Space Communications Complex near Canberra.
00:25:26.636" data-end="00:25:37.290">25:27">And this is Space Time. 25:29">Still to come, the first CubeSat mission to visit the Moon arrives in lunar orbit and 25:34">a solar snake slithers across the Sun.
00:25:40.071">25:38">All that and more still to come on Space Time.
[25:40] 25:56" data-start="00:25:40.080" data-end="00:25:55.920">Music.
[25:56] 00:26:07.245">While NASA's Artemis 1 mission was making its way to the Moon, a much smaller spacecraft, 26:03">no bigger than a bread box, successfully slipped into lunar orbit.
00:26:11.570">NASA's Capstone mission is the first CubeSat to arrive at the Moon.
[26:12] 00:26:12.205" data-end="00:26:23.745">The tiny 25 kilogram probe is now in a near-rectilinear halo orbit, a highly elliptical path that 26:19">will eventually be occupied by NASA's Lunar Gateway Space Station when it's built over
00:26:37.025">26:24">coming years. Gateway will act as a base camp for future Artemis missions down to the lunar 26:30">surface. Its first modules are expected to be in position sometime after 2024. Capstone,
00:26:42.412">the CIS Lunar Autonomous Positioning System Technology Operations and Navigation experiment,
00:26:47.585">26:43">is designed to study this orbit to ensure that it will be suitable for the future Gateway,
00:26:56.745">26:48">Space Station. The orbit marks a Lagrange position between the Earth and the Moon, 26:53">where the gravitational interactions between the two bodies cancel each
00:27:05.145">26:57">other out, thereby creating a gravitational well which could keep a 27:00">spacecraft stable in position. It's the first time a spacecraft has been in this
00:27:22.505">orbit and Capstone will aim to verify the suspected suitability of the orbit over 27:10">the next six months. Capstone will also perform a series of 27:14">communications and navigational tests. They'll be in concert with NASA's Lunar 27:19">Reconnaissance Orbiter spacecraft which has been orbiting the Moon since 2009.
00:27:31.663">27:23">The CubeSat is now undertaking a series of cleanup maneuvers designed to ensure 27:28">or the spacecraft is inserted precisely into its correct orbit.
[27:32] 00:27:32.285" data-end="00:27:47.975">Capstone was launched on an Electron rocket from New Zealand on June 28. 27:38">It was placed on a highly fuel-efficient 4.5-month-long trek using gravitational contours 27:43">between the Earth and the Moon to reach its target. But it's not been a smooth flight,
00:27:57.895">27:48">it's had a number of problems. The first saw mission managers lose contact with the probe 27:53">on July 4 just after it separated from its Electron proton upper stage kick motor.
[27:59] 00:27:58.634" data-end="00:28:10.823">That was eventually tracked down to an improperly formatted command which was 28:02">quickly corrected. Then two months later on September the 8th, Capstone suffered 28:07">another issue during a planned trajectory correction engine burn when,
00:28:18.935">28:11">it suddenly began to tumble out of control forcing the spacecraft to enter 28:15">a protective safe mode. That issue was eventually traced to a faulty
00:28:38.655">28:19">propulsion system valve and a workaround was developed. Of course Capstone won't 28:24">be the only CubeSat in lunar orbit for long. It'll shortly be joined by 11 28:29">fellow CubeSats deployed from NASA's Artemis 1 mission. And while Capstone is 28:34">the first CubeSat to achieve lunar orbit, it's not the first to leave Earth orbit.
00:28:39.154" data-end="00:28:49.015">That honor goes to NASA's twin Marko probes, which were deployed from the 28:43">Mars InSight lander back in 2018 to study the Red Planet. This is space-time.
00:28:58.335">Still to come, a solar snake slithers across the Sun and later in the science 28:55">report meteorologists warn that Australia needs to prepare for
00:29:09.671">increasing floods and droughts caused by an acceleration of the El Nino 29:03">southern oscillation index due to climate change. All that and more still 29:07">to come on Space Time.

[29:25] 00:29:34.962">The European Space Agency's Solar Orbiter has imaged a massive flash of plasma streaking 29:31">a third of the way across the face of the Sun.
00:29:45.932">29:35">Astronomers say this spectacular event was actually a surge of cooler atmospheric gases 29:40">snaking through hotter surrounding plasma and suspended by a long filament of the Sun's magnetic field.
00:29:46.582" data-end="00:29:56.159">29:47">The observations, which were a precursor to a much larger eruption, provided an intriguing 29:51">new addition to the zoo of features revealed so far by the Solar Orbiter mission.
00:30:06.025">29:57">The event, which astronomers are referring to as a solar snake, was seen on September 30:01">5 as Solar Orbiter was approaching the Sun for its October 12 close flyby.
00:30:09.023">30:07">Plasma is a fourth state of matter.
[30:10] 00:30:20.105">While relatively rare on Earth, it's the most common state of matter in the universe. 30:14">It's actually a superheated ionized gas stripped of electrons, which on Earth is commonly seen 30:19">as lightning.
00:30:26.713">30:21">The loss of electrons makes the gas electrically charged and therefore susceptible to magnetic fields.
00:30:27.361" data-end="00:30:41.305">All the gas in the Sun's atmosphere is a plasma because the temperature here is more than a million degrees Celsius. 30:34">The study's lead author David Long from the Mallard Space Science Laboratory says the plasma snake was seen flowing from one side of the Sun to the other.
00:30:51.397">30:42">The magnetic field was extremely twisted, causing changes in the plasma's direction. 30:47">The observations were captured by Solar Orbiter's ultraviolet imager.
00:30:59.822">30:52">The snake took around three hours to complete its journey across the face of the Sun, meaning 30:56">it was traveling at around 170 km per second.
00:31:00.525" data-end="00:31:10.775">31:01">What makes the snake so intriguing is that it began from a solar-active region 31:05">that later erupted as a coronal mass ejection, ejecting billions of tons of plasma into space.
[31:12] 00:31:11.544" data-end="00:31:20.855">And this raises the possibility that the snake was a sort of precursor to this event. 31:17">And the good thing there is Solar Orbiter caught it using all its instruments.
[31:22] 00:31:21.672" data-end="00:31:28.135">For the spacecraft's energetic particle detector, 31:24">the eruption was one of the most intense solar particle events it had seen.
00:31:37.200">And, fortuitously, the eruption also swept over NASA's Parker Solar Probe, allowing 31:34">its instruments to also measure the coronal mass ejection.
[31:38] 00:31:49.317">Being able to witness a coronal mass ejection take place, and then sample its ejected gases, 31:43">either with its own instruments or those of another spacecraft, is one of Solar Orbiter's 31:47">primary scientific aims.
00:31:58.374">31:50">It allows astronomers to get a better understanding of solar activity, and the weight creates 31:54">space weather, which can disrupt satellites and other technologies on Earth.
00:32:10.167">31:59">Launched in February 2020, the 1.8 tonne solar orbiter is a sun-observing satellite, designed 32:05">to obtain detailed measurements of the inner heliosphere and the nascent solar wind.
00:32:24.507">32:11">Its mission includes a series of gravity assists of both the Earth and Venus, which will allow 32:16">the spacecraft to move out of the planetary plane of the solar system and observe the 32:20">Sun's little-understood polar regions, which are difficult to study from Earth.
00:32:25.215" data-end="00:32:35.652">These observations will be important in understanding how the Sun creates and controls its heliosphere, 32:31">the atmospheric region of the Sun that bathes the entire solar system.
00:32:36.335" data-end="00:32:45.609">In June 2020, Solar Orbiter came within 77 million kilometers of the Sun, capturing the 32:42">closest observations of the Sun ever undertaken at that time.

00:33:33.087" data-end="00:33:46.563">Scientists say that ocean surface temperature changes in the Eastern Pacific and the weather that comes with it, 33:38">namely the El Nino and La Nina events, are likely to be more and more detectable by 2030 under current climate change projections.
00:33:47.067" data-end="00:33:58.644">The findings reported in the journal Nature Communications are based on studies looking at 70 years of data on ENSO, 33:54">the El Nino Southern Oscillation, which sees the Pacific climate naturally isolate,

00:34:03.326" data-end="00:34:14.236">Combining this data with climate models, meteorologists say climate change-related variations in ENSO 34:09">events will be detectable in the eastern Pacific region within eight years.

00:34:50.506">Scientists have always puzzled as to why the Great Barrier Reef only formed around half 34:45">a million years ago when Australia already had conditions appropriate for reef growth much earlier.
00:34:51.037" data-end="00:35:10.104">Now, a report in the journal Nature Geoscience claims the answer might be Fraser Island. 34:57">Researchers found that the development of Fraser Island dramatically reduced sediment 35:01">supply to the continental shelf north of the island and this facilitated widespread coral 35:06">reef formation in the southern and central Great Barrier Reef.

00:35:46.779">35:37">The researchers say that while GABA concentration in adults stayed constant during the experiment, 35:42">kids received a rapid GABA boost during that training that lasted long after the training had ended.
00:35:47.386" data-end="00:35:53.342">The findings suggest that this could be the reason why kids seem to pick up new skills 35:52">faster than adults.
[35:55] 00:35:54.791" data-end="00:36:04.721">Well, it's not often we get to test out psychic predictions in real time, but we get to do so this week. 36:01">It seems the psychic called Aaron Lazar has issued a warning on his TikTok channel,
00:36:17.351">36:05">claiming that a major world event involving the Atlantic Ocean will be happening along the West 36:10">Irish coast in November. Okay, so we're in November, let's wait and see. No pun intended, what happens.
00:36:30.561">36:18">Tim Mendham from Australian Skeptics says these sort of predictions are usually kept fairly vague, 36:23">but Lazar has narrowed it all down. So a major world event, the Atlantic Ocean and the West Irish coast.
[36:31] 00:36:31.322" data-end="00:36:43.097">Can't wait. There's a psychic who is also he's a channel, he's an ascension mentor, he's an 36:38">Akashic realm expert and a weatherman too apparently because he predicts that the.
[36:43] 00:36:43.281" data-end="00:36:52.521">West coast of Ireland is going to go under in just weeks. No, no hold on, hold on, I can't get away 36:48">away with any of that. I know what a weatherman is. What were some of those others?
00:37:04.041">36:53">He's an Akashic realm expert. Now Akashic comes from the religion in quotes called Theosophy, 36:59">which was started off, started up in the 19th century by Madame Blavatsky, who was a bit
00:37:22.383">of a mystic herself. She was quite critical of a lot of psychics actually, honestly, and 37:08">she wasn't a bit skeptical too, in some areas, but not in others. But this is a bit of a 37:14">pseudo religion, bit of a pseudo philosophy, a bit of things mixed in together. So this 37:17">goes a Kashik Realm expert, he's also a psychic of course, he's a channeler, he channels spirits,
00:37:32.001">of dead people or spirits that never lived, aliens or whatever, ancient gods you name 37:27">it, they can channel all sorts of things and give you advice which is always pretty vague 37:31">in the name but never mind.
00:37:34.761">As sentient mental, I'm not even going to try and figure out what that one is.
[37:35] 00:37:44.071">Somewhere to help you climb the ladder or something. 37:37">I don't know. 37:38">Anyway, so this guy was predicting that the west of Ireland would be hit by a major, in 37:42">quotes, world event in just weeks.
00:37:56.191">Now, it's been hard to say exactly what the major world event was going to be until you've 37:48">read further down through the story that he's telling people to keep an eye on the water 37:52">and have a go bag and some cash ready in case they need to evacuate.
00:38:05.931">Now, presumably keep an eye on the water means there's going to be a tsunami or some sort 38:00">of thing like that and the go bag means you have your suitcase by the door and you go 38:03">when the water is approaching or even your toilet's on its way.
00:38:12.931">38:06">This was supposed to happen. 38:08">As a journalist, I always have a go bag, spare phone. 38:11">That's right. You have it ready to go and your passport.
00:38:13.066" data-end="00:38:14.668">Passport, all that sort of stuff. Lots of cash.
[38:15] 00:38:14.931" data-end="00:38:20.971">And a book, and a good book to read on the way. 38:19">I have my phone, so that's good.
00:38:30.899">38:21">This appeared in a story that, I'm not sure when the actual prediction was made, but it 38:26">appeared in a story that I saw in a publication in about mid September.
00:38:31.131" data-end="00:38:43.571">Weeks might have passed by then actually and if you haven't seen the west of Ireland wiped 38:36">out by a major world event, then you might suggest that this Akashic expert channeler 38:42">etc. is actually a little bit off.
00:38:50.479">38:44">But it's nice to make predictions because you get the publicity then and then as we 38:47">always say, no one bothers going back to the same thing, but hey, you were wrong.
00:39:01.651">38:51">This is what's going to happen. 38:52">Apparently, Holland and things are okay because Ireland and the UK are protecting Holland, 38:58">Netherlands, etc. from this sort of major world event, this big tsunami, whatever it is.
00:39:07.530">39:02">The French coast is not going to do so good, but apparently we don't care about the French coast 39:05">because this is an Irish psychic and he's worried about Ireland.
00:39:14.083">39:08">Some people are saying, oh my God, I can see the Atlantic now. 39:10">And they say this is amazing stuff. 39:13">But of course, yeah, it hasn't happened.
00:39:16.730">That's Tim Mendham from Australian Skeptics.
