NASA's Historic Artemis 3 Crew, Early Launch for Roman Telescope, and a Solar Storm Spectacle

In today's episode, Anna and Avery cover six major stories: NASA's historic Artemis III crew announcement, the official August 30 launch date for the Roman Space Telescope, a G3 geomagnetic storm delivering northern lights to mid-latitudes, a worrying air leak aboard the International Space Station, the fallout from Blue Origin's New Glenn explosion and its impact on NASA's Moon programme, and JAXA's H3 rocket attempting a redemption launch tonight. Stories Covered • BREAKING: NASA announces the four-person crew for Artemis III at Johnson Space Center -- a mission redesignated as a low-Earth-orbit docking rehearsal, paving the way for the Artemis IV Moon landing in 2028. • NASA officially sets August 30, 2026 as the launch date for the Nancy Grace Roman Space Telescope -- eight months ahead of schedule. Roman will survey the sky 100x wider than Hubble, targeting dark energy, dark matter and exoplanets. • A cannibal coronal mass ejection -- two merged CMEs -- arrives at Earth triggering a G3 geomagnetic storm, with auroras visible to mid-northern latitudes on June 8-9. • Crew aboard the ISS briefly shelters in the docked SpaceX Dragon on June 5 as a worsening air leak in the Russian Zvezda module's PrK transfer tunnel prompts precautionary evacuation procedures. • NASA seeks an alternative launch vehicle for Blue Origin's Blue Moon lander following the catastrophic May 28 New Glenn explosion at Cape Canaveral, which destroyed LC-36 and threatened the autumn cargo lander demonstration flight. • JAXA launches the H3 rocket (H3-30 variant) tonight from Tanegashima on a test flight -- Japan's first large rocket powered entirely by liquid engines -- following the December 2025 failure that lost the QZS-5 navigation satellite.

00:00:00 --> 00:00:03 Anna: Hello and welcome to Astronomy Daily.

00:00:03 --> 00:00:04 I'm Anna.

00:00:04 --> 00:00:06 Avery: And I'm, um, Avery. You're listening to

00:00:06 --> 00:00:09 season five, episode 115. And our

00:00:09 --> 00:00:11 team has lined up quite a Tuesday for us

00:00:11 --> 00:00:11 today.

00:00:11 --> 00:00:14 Anna: They really have. We've got a historic

00:00:14 --> 00:00:17 crew announcement from NASA, a brand new

00:00:17 --> 00:00:20 launch date for the most powerful Wide Field

00:00:20 --> 00:00:23 telescope ever built, A solar storm

00:00:23 --> 00:00:25 that put on a light show over much of the

00:00:25 --> 00:00:27 Northern Hemisphere, a space station

00:00:27 --> 00:00:29 emergency and and more.

00:00:29 --> 00:00:31 Avery: And we'll close out with the rocket comeback

00:00:31 --> 00:00:34 story that's happening right now tonight as

00:00:34 --> 00:00:37 we record this. So stay with us all the way

00:00:37 --> 00:00:37 to the end.

00:00:38 --> 00:00:40 Anna: This is Astronomy Daily. Let's get into it.

00:00:41 --> 00:00:43 Avery: Our lead story today is breaking news and

00:00:43 --> 00:00:46 it's big. Earlier this morning at

00:00:46 --> 00:00:49 11:00am, um, Eastern Time, NASA held a

00:00:49 --> 00:00:51 live event at Johnson Space center in Houston

00:00:52 --> 00:00:54 and officially announced the four person crew

00:00:54 --> 00:00:55 for Artemis 3.

00:00:56 --> 00:00:58 Anna: Now, some of our listeners might be

00:00:58 --> 00:01:01 wondering, Artemis 3, isn't that the

00:01:01 --> 00:01:03 moon landing? And the answer is it was

00:01:04 --> 00:01:06 and then it wasn't. And now the crew is

00:01:06 --> 00:01:07 finally official.

00:01:08 --> 00:01:10 Avery: Let me explain what Artemis 3 actually is

00:01:10 --> 00:01:13 now. Back in February this year, NASA

00:01:13 --> 00:01:16 Administrator Jared Isaacman made a big

00:01:16 --> 00:01:18 announcement. Artemis 3 would no longer be

00:01:18 --> 00:01:20 the mission to land humans on the moon.

00:01:21 --> 00:01:23 Instead, it's been redesignated as a low

00:01:23 --> 00:01:25 Earth orbit docking demonstration.

00:01:26 --> 00:01:29 Anna: Think of it as NASA's version of Apollo 9.

00:01:29 --> 00:01:32 In 1969, before Apollo 11

00:01:32 --> 00:01:35 landed on the moon, NASA sent Apollo 9

00:01:35 --> 00:01:38 to test the lunar module in Earth orbit,

00:01:38 --> 00:01:40 practicing every rendezvous and docking

00:01:40 --> 00:01:43 maneuver they'd need. Artemis 3 is doing

00:01:43 --> 00:01:46 exactly the same thing half a century

00:01:46 --> 00:01:46 later.

00:01:47 --> 00:01:49 Avery: This is critical work. You cannot send

00:01:49 --> 00:01:51 astronauts to dock with the lander on the

00:01:51 --> 00:01:54 moon if you haven't proven those docking

00:01:54 --> 00:01:56 systems were closer to home first. The

00:01:56 --> 00:01:59 Artemis program takes no shortcuts.

00:01:59 --> 00:02:02 Anna: So who's going? That's the big news from

00:02:02 --> 00:02:05 this morning. The crew names were officially

00:02:05 --> 00:02:07 unveiled during the Johnson Space center

00:02:07 --> 00:02:09 broadcast just hours ago. As we record this

00:02:09 --> 00:02:12 episode, full details are on NASA's website

00:02:12 --> 00:02:14 and we'll link everything in the show notes.

00:02:15 --> 00:02:17 Avery: What we can say is that NASA has been looking

00:02:17 --> 00:02:20 for astronauts with exceptional spacewalk

00:02:20 --> 00:02:23 experience, piloting skills, and hands on

00:02:23 --> 00:02:25 time with Artemis hardware. The crew of

00:02:25 --> 00:02:27 Artemis II, which splashed down in the

00:02:27 --> 00:02:30 Pacific on April 10, demonstrated those

00:02:30 --> 00:02:33 qualities spectacularly. And today's

00:02:33 --> 00:02:35 announcement sets the stage for what comes

00:02:35 --> 00:02:35 next.

00:02:35 --> 00:02:38 Anna: And what comes Next after Artemis 3 is

00:02:38 --> 00:02:41 Artemis 4, which has now become the mission

00:02:41 --> 00:02:44 carrying the first human boots back on lunar

00:02:44 --> 00:02:47 soil since Apollo 17 in

00:02:47 --> 00:02:49 December 1972 that is

00:02:49 --> 00:02:52 currently targeted for early 2028.

00:02:52 --> 00:02:55 Avery: So today is a Milestone day. A crew has

00:02:55 --> 00:02:58 a name. The next chapter of human space

00:02:58 --> 00:03:00 exploration has faces on it.

00:03:00 --> 00:03:03 Anna: History in the making. We'll have full crew

00:03:03 --> 00:03:05 coverage and follow up in tomorrow's episode

00:03:05 --> 00:03:07 as the world reacts.

00:03:07 --> 00:03:09 Avery: Our second story comes with a launch date.

00:03:09 --> 00:03:12 And it's sooner than almost anyone expected.

00:03:12 --> 00:03:15 NASA has officially set August 30,

00:03:15 --> 00:03:18 2026 as the launch date for the Nancy Grace

00:03:18 --> 00:03:20 Roman Space Telescope.

00:03:20 --> 00:03:23 Anna: That is eight months ahead of the agency's

00:03:23 --> 00:03:25 previous commitment to flying no later than

00:03:25 --> 00:03:28 May 2027. This is a genuine

00:03:28 --> 00:03:30 success story in a program that has had its

00:03:30 --> 00:03:33 share of delays and budget pressures over the

00:03:33 --> 00:03:33 years.

00:03:34 --> 00:03:37 Avery: So what is Roman and why are astronomers so

00:03:37 --> 00:03:40 excited? The Roman Space Telescope is a

00:03:40 --> 00:03:42 wide field infrared observatory, and its

00:03:42 --> 00:03:45 defining feature is sheer width. Its

00:03:45 --> 00:03:47 Wide field instrument has a field of view at

00:03:47 --> 00:03:50 least 100 times larger than the Hubble Space

00:03:50 --> 00:03:53 Telescope. 100 times. That

00:03:53 --> 00:03:56 is not a small difference. Where Hubble peers

00:03:56 --> 00:03:59 deep into tiny slivers of sky, Roman

00:03:59 --> 00:04:02 will sweep vast areas in a fraction of the

00:04:02 --> 00:04:04 time. It's been designed to image

00:04:04 --> 00:04:07 approximately 1 billion galaxies over its

00:04:07 --> 00:04:09 primary five year mission, with a possible

00:04:09 --> 00:04:11 five year extension after that.

00:04:11 --> 00:04:14 Anna: Its primary scientific targets are dark

00:04:14 --> 00:04:17 energy, dark matter and exoplanets.

00:04:17 --> 00:04:20 On the exoplanet side, Roman will conduct a

00:04:20 --> 00:04:23 gravitational microlensing survey expected

00:04:23 --> 00:04:25 to discover more than a thousand new

00:04:25 --> 00:04:27 worldsplanets that would be completely

00:04:27 --> 00:04:30 invisible to any other current telescope.

00:04:30 --> 00:04:33 Avery: Engineers are currently packing Roman at

00:04:33 --> 00:04:35 NASA's Goddard Space Flight center in

00:04:35 --> 00:04:37 Maryland, ready for shipment down to Kennedy

00:04:37 --> 00:04:40 Space center in Florida. Once there, it'll

00:04:40 --> 00:04:42 move into the Payload Hazardous Servicing

00:04:42 --> 00:04:44 Facility for a thorough inspection, power

00:04:44 --> 00:04:47 testing, launch rehearsals, and the loading

00:04:47 --> 00:04:49 of about 290 gallons of

00:04:49 --> 00:04:51 hydrazine propellant.

00:04:51 --> 00:04:54 Anna: It will launch on a SpaceX Falcon Heavy from

00:04:54 --> 00:04:57 Kennedy. Given Falcon Heavy's track record

00:04:57 --> 00:04:59 and the level of preparation the Roman team

00:04:59 --> 00:05:01 has put in, the space community is feeling

00:05:01 --> 00:05:03 genuinely optimistic.

00:05:03 --> 00:05:05 Avery: And this is an important distinction from

00:05:05 --> 00:05:08 Webb, which we talk about often. Webb looks

00:05:08 --> 00:05:11 deep but narrow. Roman will survey

00:05:11 --> 00:05:13 wide and fast. The two telescopes are

00:05:13 --> 00:05:16 complementary. Roman will identify

00:05:16 --> 00:05:18 extraordinary targets that Webb can then

00:05:18 --> 00:05:20 follow up on in painstaking detail.

00:05:21 --> 00:05:23 Anna: Think of it as Roman casting the net and

00:05:23 --> 00:05:26 Webb examining what's in it. Together, they

00:05:26 --> 00:05:28 are the most powerful pair of space

00:05:28 --> 00:05:31 observatories humanity has ever operated

00:05:31 --> 00:05:32 simultaneously.

00:05:32 --> 00:05:35 Avery: August 30th is the date. Mark your calendars

00:05:36 --> 00:05:37 from the far future

00:05:37 --> 00:05:39 Anna: to the very recent past.

00:05:39 --> 00:05:42 Our third story is about what the sun did to

00:05:42 --> 00:05:45 us this week. And the answer is it threw a

00:05:45 --> 00:05:46 cannibal at us.

00:05:46 --> 00:05:49 Avery: A cannibal. Coronal mass ejection to be

00:05:49 --> 00:05:51 precise. And yes, that is the actual

00:05:51 --> 00:05:53 scientific term. Let us explain.

00:05:54 --> 00:05:57 Anna: It started with an M M class solar flare from

00:05:57 --> 00:05:58 active sunspot region

00:05:58 --> 00:06:01 AR4461. On June 6,

00:06:02 --> 00:06:04 that flare launched a coronal mass ejection,

00:06:04 --> 00:06:07 a huge cloud of magnetized plasma toward

00:06:07 --> 00:06:10 Earth. So far that's not unusual. The

00:06:10 --> 00:06:11 sun does this regularly.

00:06:12 --> 00:06:15 Avery: What made this one special was that a second

00:06:15 --> 00:06:17 faster CME erupted not long after

00:06:17 --> 00:06:20 that second ejection caught up with and

00:06:20 --> 00:06:23 merged with the first, creating a combined

00:06:23 --> 00:06:25 more powerful event. When a faster

00:06:25 --> 00:06:28 CME overtakes a slower one and they

00:06:28 --> 00:06:30 combine, scientists call it a cannibal

00:06:30 --> 00:06:31 CME.

00:06:31 --> 00:06:34 Anna: The merged cloud arrived at Earth on June 8,

00:06:34 --> 00:06:37 and both NOAA and the UK Met Office

00:06:37 --> 00:06:39 had already issued a G3.

00:06:40 --> 00:06:42 That's strong geomagnetic storm watch.

00:06:43 --> 00:06:45 To put that in context, the scale runs from

00:06:45 --> 00:06:48 G1 up to G5.

00:06:48 --> 00:06:51 Extreme G3 means Aurora

00:06:51 --> 00:06:54 displays are possible as far south as mid

00:06:54 --> 00:06:57 northern latitudes. Think Oregon, Illinois

00:06:57 --> 00:06:58 or Northern England.

00:06:59 --> 00:07:01 Avery: For our uh, listeners in Australia and New

00:07:01 --> 00:07:03 Zealand, you'd want to be watching from the

00:07:03 --> 00:07:05 southern island of New Zealand or Tasmania to

00:07:05 --> 00:07:07 catch the aurora australis during an event

00:07:07 --> 00:07:10 like this. And even then it's a close call.

00:07:10 --> 00:07:13 But the Northern hemisphere had quite the

00:07:13 --> 00:07:13 show on the 8th.

00:07:14 --> 00:07:17 Anna: The geomagnetic activity was still elevated

00:07:17 --> 00:07:19 into today June 9th, with a G2

00:07:19 --> 00:07:22 watch remaining in place. And there's a

00:07:22 --> 00:07:25 delicious coincidence here. June 9th is also

00:07:25 --> 00:07:27 the night of the Venus Jupiter conjunction.

00:07:27 --> 00:07:30 The two brightest planets appearing less than

00:07:30 --> 00:07:33 2 degrees apart in the western sky after

00:07:33 --> 00:07:35 sunset. So people who went outside to watch

00:07:35 --> 00:07:37 the conjunction may also have caught a

00:07:37 --> 00:07:39 glimpse of the aurora.

00:07:39 --> 00:07:41 Avery: The sun is currently very active. There are

00:07:41 --> 00:07:44 multiple sunspot regions on the Earth facing

00:07:44 --> 00:07:47 side right now and a large coronal hole

00:07:47 --> 00:07:49 rotating into an Earth directed position,

00:07:49 --> 00:07:52 meaning further geomagnetic activity in the

00:07:52 --> 00:07:54 days ahead is possible. Keep your eyes on the

00:07:54 --> 00:07:57 sky folks. Space weather is being generous

00:07:57 --> 00:07:57 this week.

00:07:58 --> 00:08:00 Anna: Moving on to the International Space Station

00:08:00 --> 00:08:03 and a story that caused hearts to race last

00:08:03 --> 00:08:06 Friday at uh, just 1:00pm UTC.

00:08:06 --> 00:08:08 On June 5th, NASA ordered the crew aboard uh,

00:08:09 --> 00:08:11 the ISS to don spacesuits,

00:08:11 --> 00:08:14 shelter inside the docked SpaceX Dragon

00:08:14 --> 00:08:16 spacecraft and prepare for potential

00:08:16 --> 00:08:17 evacuation.

00:08:17 --> 00:08:20 Avery: To be clear from the outset, the crew was

00:08:20 --> 00:08:22 safe and within about two hours they received

00:08:22 --> 00:08:25 the all clear to return to normal operations.

00:08:25 --> 00:08:27 But the reason this happened is something the

00:08:27 --> 00:08:30 ISS program has been managing for years

00:08:30 --> 00:08:32 and it is getting harder to manage.

00:08:33 --> 00:08:35 Anna: The issue is the Zvezda service

00:08:35 --> 00:08:38 module, specifically a transfer tunnel

00:08:38 --> 00:08:41 section called the prk. It's part of The

00:08:41 --> 00:08:43 Russian segment of the station, and it has

00:08:43 --> 00:08:46 been developing cracks and small atmospheric

00:08:46 --> 00:08:47 leaks since 2019.

00:08:48 --> 00:08:50 Roscosmosthat's the Russian space

00:08:50 --> 00:08:53 agency has been applying sealants and

00:08:53 --> 00:08:56 mitigation measures continuously. But the

00:08:56 --> 00:08:57 cracks keep developing.

00:08:57 --> 00:09:00 Avery: On June 5, new leaks were found in the

00:09:00 --> 00:09:02 tunnel during what was meant to be a more

00:09:02 --> 00:09:05 extensive repair operation. Russian crew

00:09:05 --> 00:09:07 members paused the repair work to assess the

00:09:07 --> 00:09:10 new measurements. And NASA, out of an

00:09:10 --> 00:09:12 abundance of caution, ordered the four non

00:09:12 --> 00:09:14 Russian crew members to shelter in the

00:09:14 --> 00:09:15 Dragon.

00:09:15 --> 00:09:18 Anna: The repair assessment eventually allowed them

00:09:18 --> 00:09:21 to stand down. NASA says they are continuing

00:09:21 --> 00:09:23 to monitor the situation very closely,

00:09:23 --> 00:09:26 working with Roscosmos on a solution. But

00:09:26 --> 00:09:28 this is an aging station. It's been

00:09:28 --> 00:09:31 continuously inhabited for over 25

00:09:31 --> 00:09:34 years now, built beginning in November

00:09:34 --> 00:09:37 1998, and the structural pressures are

00:09:37 --> 00:09:37 real.

00:09:38 --> 00:09:40 Avery: The current plan is to operate the ISS

00:09:40 --> 00:09:43 through the end of 2030 with a controlled

00:09:43 --> 00:09:45 deorbit and destructive re entry in early

00:09:45 --> 00:09:48 2031. Whether the PRK

00:09:48 --> 00:09:50 tunnel can be kept sealed and safe for

00:09:50 --> 00:09:53 another four plus years is one of the more

00:09:53 --> 00:09:55 pressing questions facing the program right

00:09:55 --> 00:09:55 now.

00:09:55 --> 00:09:58 Anna: For now, the crew is safe and working, but

00:09:58 --> 00:10:00 this story will be one to watch.

00:10:00 --> 00:10:03 Avery: Story five brings us up to speed on the

00:10:03 --> 00:10:05 fallout from Blue Origin's catastrophic

00:10:05 --> 00:10:07 rocket explosion, and it is having

00:10:07 --> 00:10:09 significant ripple effects on NASA's entire

00:10:09 --> 00:10:10 lunar program.

00:10:11 --> 00:10:13 Anna: Here's the background for listeners who may

00:10:13 --> 00:10:15 have missed it. On May 28, Blue

00:10:15 --> 00:10:18 Origin's new Glenn rocket exploded during a

00:10:18 --> 00:10:21 static fire test AT Launch Complex

00:10:21 --> 00:10:24 36 at Cape Canaveral Space Force Station.

00:10:24 --> 00:10:26 A, uh, static fire test is when you ignite

00:10:26 --> 00:10:29 the engines while the rocket is still on the

00:10:29 --> 00:10:32 pad, bolted down to check their performance

00:10:32 --> 00:10:33 ahead of a real launch.

00:10:33 --> 00:10:36 Avery: The explosion was enormous, visible from

00:10:36 --> 00:10:39 more than a hundred miles away. The rocket

00:10:39 --> 00:10:42 was destroyed. The transporter and erector

00:10:42 --> 00:10:44 holding it in place was wrecked. A lightning

00:10:44 --> 00:10:47 tower was demolished. The main gantry

00:10:47 --> 00:10:50 suffered structural damage. Satellite images

00:10:50 --> 00:10:52 captured the full scorched extent of the

00:10:52 --> 00:10:53 destruction.

00:10:53 --> 00:10:56 Anna: No one was injured, which, given the scale of

00:10:56 --> 00:10:59 the explosion, is remarkable. Blue Origin

00:10:59 --> 00:11:01 CEO Dave Limp has said the pad can be

00:11:01 --> 00:11:04 repaired faster than initially feared. Key

00:11:04 --> 00:11:06 infrastructure, including the propellant

00:11:06 --> 00:11:09 tanks, water tower and storage systems,

00:11:09 --> 00:11:11 survived intact. He's committed to having

00:11:11 --> 00:11:14 another new Glenn ready for launch before the

00:11:14 --> 00:11:15 end of 2026.

00:11:16 --> 00:11:18 Avery: That is an ambitious timeline, though, and

00:11:18 --> 00:11:21 the consequences for NASA's lunar program are

00:11:21 --> 00:11:24 serious. Blue Origin was supposed to launch

00:11:24 --> 00:11:26 its Blue Moon Mark one cargo lander, an

00:11:26 --> 00:11:29 uncrewed demonstrator intended to deliver a

00:11:29 --> 00:11:31 NASA Paylo to the moon this autumn. Um, as

00:11:31 --> 00:11:33 the inaugural mission of the Moon based

00:11:33 --> 00:11:34 program.

00:11:34 --> 00:11:37 Anna: With New Glenn out of action and LC

00:11:37 --> 00:11:40 36 in ruins, NASA Administrator

00:11:40 --> 00:11:42 Jared Isaacman is now describing what he

00:11:42 --> 00:11:45 calls a whole of government response. The

00:11:45 --> 00:11:47 agency is actively seeking an alternative

00:11:47 --> 00:11:50 launch vehicle for the Blue Moon lander,

00:11:50 --> 00:11:52 decoupling it from New Glenn entirely for

00:11:52 --> 00:11:53 now.

00:11:53 --> 00:11:55 Avery: And um, there's a direct connection to

00:11:55 --> 00:11:57 Artemis 3, the crew we just told you about in

00:11:57 --> 00:12:00 story one. Artemis 3 is meant to dock with

00:12:00 --> 00:12:03 both the SpaceX Lander variant and Blue

00:12:03 --> 00:12:06 Moon Mark 2 in Low Earth orbit. If Blue

00:12:06 --> 00:12:08 Origin's hardware isn't flight proven before

00:12:08 --> 00:12:10 then, that mission profile becomes

00:12:10 --> 00:12:12 significantly more complicated.

00:12:12 --> 00:12:15 Anna: Administrator Isaacman has said he remains

00:12:15 --> 00:12:17 optimistic about a crewed lunar landing in

00:12:17 --> 00:12:20 2028 using whatever landing craft

00:12:20 --> 00:12:23 is available. But the road to the moon just

00:12:23 --> 00:12:24 got a bit bumpier.

00:12:25 --> 00:12:27 And for our final story, something that is

00:12:27 --> 00:12:30 actually happening right now tonight as

00:12:30 --> 00:12:33 we broadcast this episode. The Japan

00:12:33 --> 00:12:35 Aerospace Exploration Agency

00:12:36 --> 00:12:39 is attempting to launch its H3 rocket

00:12:39 --> 00:12:41 from Tanegashima Space Center.

00:12:41 --> 00:12:44 Avery: This is a comeback story and JAXA really

00:12:44 --> 00:12:47 needs it to work. The H3's last flight was

00:12:47 --> 00:12:49 a painful one. Back in December last year,

00:12:49 --> 00:12:52 the rocket attempted to launch carrying a

00:12:52 --> 00:12:54 quasi Zenith satellite navigation

00:12:54 --> 00:12:57 satellite, part of Japan's own regional GPS

00:12:57 --> 00:13:00 style positioning network. The mission ended

00:13:00 --> 00:13:02 in failure when the QZS5 satellite

00:13:02 --> 00:13:05 separated from the rocket prematurely during

00:13:05 --> 00:13:07 stage separation and fell into the ocean.

00:13:08 --> 00:13:10 Anna: The cause was eventually traced to adhesive

00:13:10 --> 00:13:12 strips in the payload support structure

00:13:12 --> 00:13:15 peeling off. DAXA has made

00:13:15 --> 00:13:17 modifications to the satellite payload

00:13:17 --> 00:13:20 section to address exactly that failure

00:13:20 --> 00:13:22 mode and sensors have been installed to

00:13:22 --> 00:13:24 monitor the fix during flight.

00:13:24 --> 00:13:26 Avery: Tonight's launch is a test flight rather than

00:13:26 --> 00:13:29 an operational mission. The rocket is

00:13:29 --> 00:13:31 carrying a dummy main payload called the

00:13:31 --> 00:13:33 vehicle evaluation payload 5 or

00:13:33 --> 00:13:36 VEP 5, along with a small collection of

00:13:36 --> 00:13:38 real satellites from universities and

00:13:38 --> 00:13:39 research organizations.

00:13:40 --> 00:13:42 Anna: What makes this version of the H3

00:13:42 --> 00:13:44 particularly interesting is its engine

00:13:44 --> 00:13:46 configuration. This is the

00:13:46 --> 00:13:49 H3.3 variant. It uses

00:13:49 --> 00:13:52 three liquid fuel LE9 engines in the

00:13:52 --> 00:13:55 first stage and no solid rocket boosters at

00:13:55 --> 00:13:57 all. That makes it Japan's first large

00:13:57 --> 00:14:00 rocket powered entirely by liquid

00:14:00 --> 00:14:02 propulsion. It's a significant milestone for

00:14:02 --> 00:14:05 the country's launch capability and its

00:14:05 --> 00:14:07 ambitions to compete in the global commercial

00:14:07 --> 00:14:08 launch market.

00:14:08 --> 00:14:11 Avery: The launch Tonight opens at 9:53am M

00:14:11 --> 00:14:14 Japan Standard Time on June 10, which is

00:14:14 --> 00:14:17 8:53pm Eastern Time on June

00:14:17 --> 00:14:19 Nint. So for our uh, listeners in Australia

00:14:19 --> 00:14:22 and the Pacific, you may actually be able to

00:14:22 --> 00:14:23 watch the livestream this morning.

00:14:24 --> 00:14:27 Anna: DAXA has had an impressive H3 track record.

00:14:27 --> 00:14:30 Overall, the vehicle has successfully flown

00:14:30 --> 00:14:32 multiple times. Tonight is about proving the

00:14:32 --> 00:14:35 fix works, restoring confidence and getting

00:14:35 --> 00:14:38 back to the serious business of building

00:14:38 --> 00:14:40 Japan's independent access to space.

00:14:41 --> 00:14:43 Avery: We're rooting for them. Go H3.

00:14:44 --> 00:14:46 Anna: And that is your Astronomy Daily for Tuesday,

00:14:46 --> 00:14:49 June 9, 2026. What a

00:14:49 --> 00:14:50 day it has been.

00:14:50 --> 00:14:53 Avery: A new Artemis crew, a telescope ready to

00:14:53 --> 00:14:56 show us a billion galaxies, a solar

00:14:56 --> 00:14:59 storm painting the sky green, a space

00:14:59 --> 00:15:02 station holding its breath, a moon program

00:15:02 --> 00:15:04 rebuilding after disaster, and the

00:15:04 --> 00:15:07 rocket about to attempt its redemption.

00:15:07 --> 00:15:10 Anna: Bass never sleeps, and neither do we.

00:15:10 --> 00:15:13 Well, almost never. Tomorrow's episode will

00:15:13 --> 00:15:16 have full reaction and detail on the Artemis

00:15:16 --> 00:15:18 3 crew announcement. You won't want to miss

00:15:18 --> 00:15:18 it.
