What is the licence on these images? I can't seen anything on the site or in the HTML. I've been waiting for a new Earth Rise/Set shot (which is thankfully at least 5568x3712px from a NIKON D5). Edit: https://www.nasa.gov/nasa-brand-center/images-and-media/ > You may use this material for educational or informational purposes, including photo collections, textbooks, public exhibits, computer graphical simulations and…

There is none, they're automatically public domain.

Mostly true. There are some restrictions on images containing NASA logos or NASA employees, for example. https://www.nasa.gov/nasa-brand-center/images-and-media/

They will be posted when they get them. Right now, NASA doesn't have them because they're still on the SD cards in the capsule (probably been copied to their PCDs too). There's not a lot of bandwidth to be pushing large RAW files. They have to share the bandwidth with all of the telemetry and comms. They sent some small files down just to make some PR announcements and tease what will be coming.

There's supposed to be a 260 megabit link: https://www.nasa.gov/goddard/esc/o2o/ Maybe it's not operating as described yet?

It is operating only when it can be pointed towards Earth, while also avoiding the Sun, which did not happen during the flyby.

The laser is on one side of Orion, and when that side is not oriented towards Earth for various reasons, the optical communications cannot be used.

For continuous communications, at least when there is no interposed body, like the Moon, multiple lasers located around Orion would be needed to ensure coverage. When by the far side of the Moon, a relay orbiting around the Moon would be needed.

This is the best animation of the trajectory I've seen: https://apod.nasa.gov/apod/ap260406.html

Someone did a nice animation on YouTube. https://www.youtube.com/watch?v=PNQ7MoL7erI

I really liked this video! Orbits are hard to visualize but I think the choices here were very good.

I was hoping that they used a medium format camera like Hasselblad or something for the larger pics... but no such luck. I guess weight might have been one factor. Still, the pics are mind blowing. Out of this world, tbh

A 20.8 megapixel 5568 x 3712 pixels is not a shitty image. When we get to see those images, they will be much better than the GoPro images we're seeing

Some nice images with this resolution of the far side of the Moon have already been posted.

I wish they would’ve flown by and taken a picture of the Apollo 11 lunar landing site. I think it would’ve been a super cool throwback to the history of lunar exploration; maybe it’s just me but I think it would’ve been really exciting. It would basically be the like visiting a UNESCO (moon?) heritage site.

The main point of the voyage was to see the far side, and also to report on previously-unseen portions of the Moon that hadn't really had human coverage in the past. Since all the Apollo landings were on the near-side of the Moon, they were in fact less accessible to this crew. My disappointment lay chiefly in their L.O.S. periods, because in 2026 why does Earth lack operational satellites that could relay comms from…

Mostly because there's been very little US activity on the Moon to justify it. Orbiting the Moon can also be a pain - its gravitational field is "lumpy" - but you can manage that by making your orbit bigger (higher). See this paper if you're interested in details as they pertain to the Lunar Reconnaissance Orbiter, which has been flying since 2009: https://ntrs.nasa.gov/api/citations/20070035736/downloads/20...

China has a lunar comm relay IIRC, to support some surface operations on the far side.

I though they were going _to the moon_, not "flyby".

NASA is a pale reminiscent of its former self. Sad.

This is a new vehicle, and this is a test flight to work out the kinks before attempting a landing. It's exactly the same way Apollo was done. Go read about Apollo 8.

I have to admit, I've been an Artemis hater ($4 billion per launch lol) but the experience of watching people go back around the Moon has been incredibly inspiring, and it proves to me that maybe we can still do hard things

> $4 billion per launch This is not a lot of money on a nation-state scale. It's equal to giving every person in the US about US$12.

Newsom, Mamdani, please stay away.
