Most weeks, the internet is a place that takes things from you. This week, it gave back. Hank Green pulled together every NASA photo from the Artemis II mission, all the videos posted to Instagram and YouTube, the official mission schedule, and the public API that tracks the Orion spacecraft’s location at any given moment, and he stitched them into an interactive timeline. You scroll through ten days of crewed flight to the moon and back. You see what they saw, when they saw it, where they were when they saw it.

NASA uploads its photos to Flickr with the EXIF data intact. Flickr preserves it. NASA also publishes the spacecraft trajectory through an open API. Three pieces of public infrastructure, free for anyone to use, were sitting there waiting for someone to combine them. Hank Green did.
