Hank Green has made something really cool. Called the Artemis II Photo Timeline, it’s an interactive way to scroll through photos from NASA’s recent crewed mission to cislunar space — but pinned to NASA’s official schedule of the mission.
It is also a tribute to publicly available data. Though the timeline includes some videos published to Instagram and YouTube, the vast majority are images from Flickr. NASA usually uploads them with EXIF data intact, and Flickr preserves it. NASA also provided the mission schedule and, even better, has a public API for the position of the Orion spacecraft at any given time. Which means Green was also able to correlate the photos with where they were taken along the craft’s trajectory.
