For a few moments on April 6, the four Artemis 2 moon astronauts and the three crewmates aboard China’s Tiangong space station were farther away from each other than any other humans had ever been.
Astrophysicist and satellite tracker Jonathan McDowell noted the occasion in a series of X posts, in which he calculated the distances between Artemis 2’s Orion capsule, named “Integrity,” and Tiangong.
