Absolutely incredible.

NASA Astronaut Reid Wiseman, who commanded Artemis II, took this footage from the far side of the Moon with his iPhone.

Watch with sound on.

Very happy to see they are on the absolutely correct “all through the town” bus. Sorry “all day long” riders.

Now we’re talking

Frankly, there are already too many annular eclipses. and who decided to tilt the Moon’s orbit? I’d like a word.

The images of Earth from Artemis are amazing. But if we destroy our ability to understand (and live on) our planet, all they are is pretty pictures

A WHOLE CIVILIZATION WILL DIE TONIGHT My son needs lunch, and I have to put his backpack together, but a whole civilization will die tonight, so I'm wondering if they've closed their schools. Like, a snow day, maybe, except instead of snow it's "keep your children home so if you die, you die together" — instead of "well open back up once the plows have cleared" it's "we don't know if we'll be here tomorrow, hold your babies tight." It's just "talk" I'm told, which I've been told before. "It's how the president makes his deals." But I've never heard anyone talk about other human beings this way, and I'm not certain I can look my son in the eyes if we all agree to stomach it one more time. A civilization will die tonight, but as I zip up his backpack and kiss him off to school I think: if this is what we call leadership then I'm not entirely sure ours isn't already dead. @michaelfdubois Mukad A QuBoy @michacifdubois

Brutal.

Finally we can say what we REALLY think about the Artemis astronauts.

great article, and featuring our Hubble Space Telescope image of the "Molten Ring"

really would have loved cameras to see the Earth grow huge as Orion hurtles from apogee to perigee #Artemis

I believe the Artemis astronauts are now farther from the Earth than anyone in the last 50+ years (since Apollo)

Relatively simple physics explains why a hot Big Bang predicts the Universe should have a composition 25% helium by mass. I love teaching this in Astronomy 101 and how a strong prediction like this can be continually tested through observations of gas clouds, stars, etc.

agree they are "going to the Moon" but it won't be a lunar orbit

One thing I hadn't realized is that, unlike Apollo 8, Artemis II will not actually orbit the Moon.

I think the biggest challenge will be that the risk/reward calculus of if you’re out, you’re out is so different… convincing folks “actually you don’t want to try to smash the ball as hard as you can in all situations” and playing it safe is antithetical to a usa sports ethos

I like the way cricket does this -- if the result is within the automated system's margin of error, it stays with "umpire's call" -but- the team that challenged doesn't lose a challenge.

we should take the average of the umpire and the machine, weighted by 1/sigma^2

“I am political,” Ms. Rachel told me of her new effort to free kids from ICE detention.

“It’s political to believe that children are worthy of love … and that our care shouldn’t stop at what we look like, our family, at our religion, at a border. Mr. Rogers was very political.”
