AkaSci 🛰️The 20-minute event last night where Artemis II astronauts spoke from space, answered questions and eloquently described their experience so far and the importance of this historic mission.
Inspiring!

The Artemis II Orion spacecraft is now just over half way through on its journey to the vicinity of the moon.
It will take 3 more days to arrive near the moon as its velocity decreases over time, currently at 5,218 km/h.

A possible view from the Artemis II Orion spacecraft at 22:35 UTC April 6 of a crescent Earth setting over the limb of a crescent Moon, as visualized using the NASA Eyes on the Solar System tool. In this image, Orion has traveled past the moon and is looking over its far side.

The simulated view from the Artemis II Orion spacecraft 45 minutes later at 23:20 UTC April 6 of a crescent Earth rising over the dark lunar surface, as visualized using the NASA Eyes on the Solar System tool. In this image, Orion has traveled past the moon and is looking over its far side.
A closeup of the aurora australis over the Antarctic in the Blue Marble image highlights the thin fragile atmosphere that sustains all life on Earth. Note that South is up.
These images, the first such images taken by humans in over 54 years, remind us of the beauty and the fragility our planet, and of our shared responsibility to care of it and of each other.

Wake-up music at Artemis II Integrity earlier today - "Chappell Roan – Pink Pony Club."
"I know you wanted me to stay
But I can’t ignore the crazy visions of me in LA
And I heard that there’s a special place
Where boys and girls can all be queens every single day
I’m having wicked dreams
Of leaving Tennessee
Oh, Santa Monica
I swear it’s calling me
Won’t make my mama proud
It’s gonna cause a scene
She sees her baby girl
I know she’s gonna scream
..."

Visualization of what Artemis II astronauts will see during the lunar flyby as Integrity approaches the Moon and flies around its far side.
The flyby will last from 2:45 – 9:40 p.m. EDT on Monday, April 6, 2026.
Highlights in the 420x time-compressed video:
00:35: Earth sets behind the lunar limb
00:35 - 00:40: Earth is eclipsed by the moon for about an hour
00:40: Earth-rise on the other side of the moon.

Artemis II moon flyby visualization
Artemis II astronauts woke up on Easter Sunday to the catchy tune of "Working Class Heroes (Work)” by CeeLo Green."
"Get up, get out, go get that money
It's time to work, eh alright
Work, eh alright
Early in the morning
I'm ready and I go
It's feel like struggle
We can open up the doubts
Everybody cans crack
I got hustle in my blood
A little bit is not enough"

Still another 24 hours for lunar flyby, as Orion slows down in its orbital path, now traveling at 2,436 km/h.
OK, you figure out which torsos, hands and legs belong to which astronaut in this scene aboard Artemis II Orion, as the astronauts "conduct a full sequence of suit operations, including putting on and pressurizing their suits, performing leak checks, simulating seat entry, and assessing mobility and their ability to eat and drink."

The Moon imaged from Artemis II earlier today.
Compared to the image of the near side of moon taken from Earth (the 2nd image), this image is rotated right by about 45°, since Orion's look-angle is towards the "left side" on the moon. See post #49 for look-angles from Orion and Earth.

The Artemis II Orion spacecraft is currently 396,390.6 km from Earth, crossing the orbit of the Moon. It will go past it as the Moon slides under it, reach apogee at 23:07 UTC while observing the far side of the Moon and then head back to Earth. Closest approach to Moon = 6,550 km at 23:02 UTC.

A nice shot from inside the Artemis II Orion cabin as the astronauts prepare for the lunar flyby later today. Christina is like Batwoman, generally "hanging" upside down from the "ceiling" as she works on her assignments (also when she sleeps)🦇 😎
This is a good YouTube site to watch the trajectory and current location of the Artemis II Orion spacecraft and of the Moon.

The Artemis II astronauts will be focusing on imaging certain features of the Moon during the flyby. E.g, the Orientale and Hetrzsprung Basins.
More info at https://science.nasa.gov/resource/artemis-ii-lunar-targeting-plan/
Note that most of the Moon has been imaged and mapped at sub-meter resolution by various orbiters over the past many years.

The moon as viewed by the GoPro camera on the solar panel of the Artemis II Orion spacecraft at 21:30 UTC. The day-night line bifurcates the Moon. Part of what we see here and the area under darkness is the lunar surface on the far side of the moon.

Looks like Artemis II will lose the comm link soon, as it approaches a solar eclipse at 8:25 p.m. EDT (00:25 UTC). Comms will be back around 9:00 p.m. EDT (01:00 UTC), via the DSN site in Madrid, after batteries are recharged.

The Artemis II webcast mentioned again that astronauts will see a solar eclipse from the moon, "the first humans to ever do so."
Didn't Apollo 11 astronauts see the Sun eclipsed by the moon? Also, Apollo 12 astronauts imaged a solar eclipse caused by Earth.
Or is there some distinction between this solar eclipse and the ones during Apollo?

Perhaps, it is the proximity of Artemis II Orion to the Moon that creates the distinction?

@AkaSci @cosmos4u @markmccaughrean good question, I don't know the particulars. Could be whether or not they were in totality, or how long they were in totality, or how much of the disk was covered…
I don't even know if the Apollo 12 eclipse was something they'd explicitly planned for, but I believe it's very deliberate for #Artemis2
@AkaSci @cosmos4u @markmccaughrean the relative position could definitely affect the characteristics of the eclipse they'd observe, though, which seems like it would be pretty important to the science goal(?) of trying to observe solar plumes/etc. around the occluded disk.
I can't find very much good information about the Apollo 12 eclipse in a few quick web searches but I could definitely believe it was an annular eclipse or otherwise not quite comparable
Daniel Fischer@SnoopJ @AkaSci @markmccaughrean Both the Apollo 11 and 12 solar eclipses were (very) total: https://www.facebook.com/dan.fischer.393/posts/pfbid02mf6UK3L2j5SgPiQsJk9JVYmo6XvZwDDZ23BYpXwJPDszaSpUYzuinkMyHzh9RF8Rl and https://skyweek.wordpress.com/2019/11/24/eine-fette-sofi-fur-apollo-12-durch-die-erde/ - the crude montage https://bsky.app/profile/ridingrobots.bsky.social/post/3miunicqanc2g from the Artemis images actually bears some resemblance to the Apollo 11 eclipse image.
Mark McCaughrean@cosmos4u @SnoopJ @AkaSci Thanks for all of this, gents – very helpful ahead of my radio interview this morning (if they ever send me the Zoom link). It will certainly require some nuanced commentary on what has (& hasn’t) been done for the first time in science terms: hopefully I will have long enough to also emphasise what’s really new about this mission & more importantly, those to come, assuming landings in the south pole region.
Dr. Eric J. Fielding, PhD@markmccaughrean @cosmos4u @SnoopJ @AkaSci One of the most valuable science observations that the astronauts made was several flashes of meteorites hitting the Moon while they were in the eclipse. I did not catch the final number, but it was more than the NASA scientists expected.
@EricFielding @markmccaughrean @cosmos4u @SnoopJ
Six, according to the NASA blog at https://www.nasa.gov/blogs/missions/2026/04/06/artemis-ii-flight-day-6-crew-wraps-historic-lunar-flyby -
"They reported six light flashes created by meteoroids impacting the lunar surface while traveling many thousands of miles per hour."
It is also disappointing that NASA prefers to use Imperial units.
@AkaSci @markmccaughrean @cosmos4u @SnoopJ Worst thing about units for NASA flights is they use “nautical miles” when talking about navigation. What is that?
@EricFielding @AkaSci @cosmos4u @SnoopJ Ha – it's a space*ship* after all.
A nautical mile is at least semi-physical: it was originally 1 minute of arc at the equator, so nicely linked to celestial navigation, but is now hard-defined as 1852 metres (yes, a very mixed up unit), so ~6076 feet, 1.151 normal miles.
@EricFielding @AkaSci @cosmos4u @SnoopJ It's historically very commonly used for navigation, and by ships, aircraft, and space missions. At least by those who still think in Imperial units.
