One might consider it foolhardy for Artemis II Orion to come screaming down at 11 km/s to 191 km altitude, cross the paths of the LEO constellations and debris around 500 km, perform the TLI to adjust its speed and trajectory and race away, without colliding with anything.
But we can be assured that all that is taken care of and LEO satellites will maneuver to get out of the way as needed.

Artemis II TLI complete. All systems good.
Here is a view of Earth from the spacecraft at altitude ~200 km during the TLI.
Integrity and the 4 astronauts are now headed for the moon.
Current orbit is 202x501,181 km, but the actual values will be slightly smaller due to gravitational interaction with the moon.

It's lonely out there 😞
Artemis II Orion is now 33,668 km away, traveling at 15,347 km/h, approaching geo-sync orbit, as Earth recedes in the dark distance, while the Moon beckons.
Astronauts have plenty of work and activities to keep them busy during the mission. Live media event with the astronauts coming up soon.
Immersive 360° view video of the launch of the Artemis II mission.
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.

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 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"

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.

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.

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?

@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
@cosmos4u thanks for the added context. It seems hard to believe that NASA would have a gaffe here in claiming a first, but I suppose it's not unbelieveable and I can't think of any other asterisks.
