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?

Doesn't that require line of sight with limited receivers available? Maybe the current positioning is preventing it until the constellation changes. With the constellation that is the craft in respect to the two ground stations in a narrow patch of the US. I could not find anything about throughput rates except for the theoretical maximum but I also suspect that max is only in LEO.

Are full size/larger images available somewhere? 1920x1280px seems low. Edit: Found 'em: https://images.nasa.gov/search?page=1&media=image&yearStart=...

The external shots seem to just be from the GoPro strapped to a solar panel. Didn't seen anything that looked like the shots from the Nikons onboard. Was hoping for a couple, but I know I'm just being greedy wanting all the pics edit: exif data shows some are from a Nikon. I just want to see them all!!! My greedy line still plays

Maybe you’re being impatient, but I don’t think you’re being greedy. This is a publicly funded project. I’d say those photos belong in the public domain. Which they are.

The gravitational pull of the moon lifts up the ocean to cause tides. Well the Earth's gravitational pull is so strong on the moon that the heavier side of the moon always faces the Earth. This is called tidal locking. So the only way to ever see the far side of the moon is to go there. Humans have gone there before, but almost always during an Earth "full moon", which means the far side is unlit. We do have full ima…

But why does this not happen to planets themselves in relation to the sun?

I think the explanation is wrong: wikipedia offers a completely different explanation https://en.wikipedia.org/wiki/Tidal_locking.

Planets can become tidally locked to the sun- mercury is. Probably the timescale required for the other planets is just much longer

EDIT: Apparently mercury isn't actually tidally locked to the sun, TIL

Gorgeous, awe-inspiring photos.

Tangentially, did the NASA website move to WordPress? I thought it was Drupal, the Drupal official website even had a case study about nasa.gov. I see wp-content links on the site and there is no Drupal behaviors in JavaScript and I didn't notice any of the usual drupal classes in the source

Are the bright spots to the lower right in this photo galaxies or just camera artifacts[0]? Unreal photo either way. [0] https://images-assets.nasa.gov/image/art002e009301/art002e00...

From left to right: Saturn, Mars and Mercury.

Wonder how it feels after being out there, seeing that, then coming back like alright back in the system I go.

I can experience it just by watching these pictures, I cannot imagine how intense it must be for astronauts.

I think my favorite of all these images is https://www.nasa.gov/image-detail/amf-art002e009287/ . The sheer size difference, while simply a trick of perspective, makes Earth feel tiny and insignificant.

If you stare at the picture, there's an illusion of the shadow growing and enveloping the moon further. At least for me. Quite neat. Might be something about the eyes focusing on the dark part of the photo?

Why is normal in quotes? Do you mean visible light vs filtered monochrome with false-color outputs or infrared/radio/x-ray like some other telescopes use? Would that be the abnormal you are referring? The Apollo images were taken with Hasselblad film cameras that were "normal" cameras[0].

A camera you can order on Amazon in the next 5 minutes

I am curious to see how being namedropped by NASA affects the sales of these cameras. It's probably not as much as I am imagining but still not an insignificant number. Probably less than Nutella that accidentally flew off the shelf live on stream straight across the shot

To be fair they "only" have a 20 Mbps laser uplink from the capsule to Earth, and that's shared between all the systems and uploading images/video.

"Uplink" means Earth to spacecraft. Spacecraft to Earth is downlink.
