NASA, Artemis II and the Linux Command Line

NASA published great images from their Artemis II mission on their website. Of course, I could manually download them all one by one or burn down the planet by using an OpenClaw Agentic AI bot to download them. But, of course, there is also some command line magic to download them semi-automatically.

It is very helpful, that NASA uses a Wordpress Gallery to host these images. That provides a linkt to a .json file for every gallery in the page source. E.g. for the „Artemis II Journey to the Moon” gallery, you will find:

<link rel="alternate" title="JSON" type="application/json" href="https://www.nasa.gov/wp-json/wp/v2/gallery/980625" />

Equiped with this information, it’s just a quick wget call, some jq magic and another call to wget (the proper one, not the botched version Fedora ships; and yes, I prefer wget over curl) and we have all the images on our local disk:

wget -O- https://www.nasa.gov/wp-json/wp/v2/gallery/980625 | jq '.meta["nasa_hds_core_meta_gallery_images"][]' | xargs -I{} wget -A jpeg,jpg,bmp,gif,png --no-clobber "{}"

If you have a shorter, more elegant, different, … version, feel free to blog about it and link here :)
