But that one (art002e000193~large.jpg) is only 287kB. The Lightroom-processed one is 6.2MB. I would expect original to be heavier.
The Lightroom one was processed from raw. Also, by brightening it a lot, the noisy high-ISO grain becomes more apparent. Noise is famously incompressible, so it leads to a much larger file size.

... My only curiosity, and yeah I know orders of significance etc... Buuuuut I wonder why they didn't consider a Z5[0][1] and the Z mount 14-24, or the Z5 with an adapter for the F mount 14-24.... There's at least a pound of weight savings on the table. Specifically, I wonder if it's a fun reason? i.e. it would be interesting if there was a technical reason like 'IBIS fails miserbly' or 'increased sensor resolution a…
When you're riding a rocket that weighs 3.5 million pounds...
My understanding is it's on the order of 5-10 pounds of rocket juice to get one pound of something to LEO, thus the question.
Looking at the EXIF (with exiftool) for the image uploaded by NASA ( https://www.nasa.gov/wp-content/uploads/2026/04/art002e00019... ), apparently this was taken by a Nikon D5 with an AF-S Zoom-Nikkor 14-24mm f/2.8G ED and developed with Lightroom. It also seems like very little was done in Lightroom. Amazing... I dumped the whole EXIF here: https://gist.github.com/umgefahren/a6f555e6588a98adb74eed79d...
I'd have probably shot it wide open at f/2.8 rather than cranking the ISO up to 51200. Incredibly impressed at the steady hands for a sharp image at 1/4 s shutter speed though! Maybe they just let the camera float in space with the mirror up, triggering it remotely.
One of the reasons the D5 supposedly was chosen was because of its high dynamic and good low light performance. It can go up to ISO 3,280,000:

The D5 has been used on the ISS, including EVAs, since 2017, so is a known quantity:

whats different between this and all the other pics of earth from various space devices
I saw someone point out on reddit that this probably the first digital picture of the whole earth (well, 1 side of it) taken by a person Apollo used film and it's been a long time since anyone has gone past LEO

Before Lightroom it might have looked closer to this: https://images-assets.nasa.gov/image/art002e000193/art002e00...
But that one (art002e000193~large.jpg) is only 287kB. The Lightroom-processed one is 6.2MB. I would expect original to be heavier.
Also possibly different JPEG quality settings.

They have a Z9 on board for radiation testing, but the D5 is the primary body for imaging on this mission IIRC

The ISS now (also?) has Z9s. So they're both generally known-quantities.
Why 'spectacular' the quotes I'm sad not alive at a time like Cowboy Bebop oh well, this is a great pic, overview effect
[flagged]
> Artemis II crew take 'spectacular' image of Earth
It was described by someone else as spectacular - in this case NASA
> Artemis II crew take spectacular image of Earth
We the BBC certify that this image is officially spectacular
Not hugely important in this context. By more import, when the sentence is something like X 'commits warcrimes' against Y
