Now, we are finally colonizing the moon. Yay!! 🎉🎉🎉

Excerpt:

>NASA's Orion spacecraft reached the farthest outbound point in its journey from Earth on Monday, a distance of more than 430,000 km from humanity's home world.

>This is nearly double the distance between Earth and the Moon and is farther than the Apollo capsule traveled during NASA's lunar missions in the late 1960s and early 1970s.

>From this vantage point, on Monday, a camera attached to the solar panels on board Orion's service module snapped photos of the Moon and, just beyond, the Earth. These were lovely, lonely, and evocative images.

>"The imagery was crazy," said the Artemis I mission's lead flight director, Rick LaBrode. "It’s really hard to articulate what the feeling is. It’s really amazing to be here, and see that."

> 

>LaBrode was speaking during a news conference at Johnson Space Center in Houston, where he and other NASA officials provided an update on the progress of the mission to test out the Space Launch System rocket and Orion spacecraft.

>This uncrewed test flight is a precursor to crewed missions later this decade, including a lunar landing on the Artemis III mission.

>After it completed a successful launch, mission manager Mike Sarafin said the agency now has full confidence in the Space Launch System rocket. "The rocket is proven," he said.

> 

>Orion still has work to do, of course. Its mission will not be complete until the spacecraft maneuvers back around the Moon, returns to Earth, survives reentry into the atmosphere, splashes down into the ocean, and is recovered off the coast near San Diego, California. That is scheduled to occur on December 11.

>Understandably, NASA's engineers are thrilled by the performance of Artemis I so far. It was a long, bumpy, and costly development path to reach this mission with the Space Launch System rocket and Orion spacecraft.

>But once the vehicles began flying, their performance has met every expectation and hope of the space agency, increasing confidence in the future of the Artemis program to explore the Moon.

That picture makes me think of when someone said "I have a bad feeling about this."

You see what people like William Shatner say about “total, ominous blackness” when they have the chance to peek out of the atmosphere. Not a single star to be seen. Why is that? It definitely instills a feeling of dread.

It's an exposure thing. Because the spacecraft, the moon and earth are so bright compared to its "surroundings" the small sources of light in the background essentially disappear.

It's similar to how a bright light can ruin your night vision temporary when driving. Or how after your eyes adjust to the dark you can see way more than right after you turned the lights out.

I'm not sure what photography equipment they used onboard. I'm sure it's all custom.. However, it's purely an artifact of the equipment and the post processing of the image. A photography trick that would get better results with all the stars and such in the background would be a method called HDR (High dynamic range). This more closely captures what the human eye sees

I was thinking something like this as well - though, I’m also a photographer. Any star would just need to be as bright as the earth here to show up in the image. But, to your point, I guess they’re all too far away to emit as much brightness. I’d like to see what an HDR image looks like from this angle!

Meanwhile, I see a bunch of ads instead.

Dread?

I kinda wanna see a video of it zooming above the surface at a few hundred feet altitude at orbital speed. But this isn't KSP where I'd do stuff like that...

Inverse square law of brightness. In order to expose for the earth and moon, the stars get lost at the bottom of the dynamic range capability of the medium. Brightness of light decreases as an inverse square of the distance traveled.

When you think about how far starlight has traveled…

"Of the remaining objectives, one half is in progress, and the other half has yet to be completed. "

That is just fantastic writing.

Light pollution, and how camera sensors work, and how exposure on cameras work.

Its gets very technical if you want to dive into it, but that's why.

He didn't really get that far out of the atmosphere for enough of the "light pollution" from earth, the moon, and the sun itself to no longer have an effect - this is the same effect but multiplied with cameras.

No sometimes it is day but there is always a dark sky bc there is no atmosphere. The way it orbits, the days and nights are ~29 1/2 Earth days long. Also the way it rotates, the same side always faces earth so the earth is either always in the sky or it never is depending on where you are on the moon

You'd be able to see stars during the day, but only in special conditions where the sunlight is not visible and your eyes have had a chance to adjust.

EDIT: the above commenter removed their mention of stars, making me look like a crazy person.
