ALT In this illustration, the LINK spacecraft from Katalyst Space attaches to NASA’s Neil Gehrels Swift Observatory in preparation to gradually lift Swift back to its original altitude. LINK, a silver rectangular spacecraft with large blue solar arrays on either side, uses three robotic arms to attach to Swift, a gold spacecraft with shorter black solar arrays. Three blue thrusters fire at the bottom of LINK. Swift has a more cylindrical body with a rectangular projection at the front. The left half of the background is taken up by a view of Earth, and the blackness of space fills the right. This image is watermarked with “Artist’s concept” and “Credit: Katalyst Space.”
