@thanetric@mastodonapp.uk But so to would Artemis 2. In the reference frame of the Solar system's barycentre, Ted and #Artemis2, whilst not co-moving, have similar paths now that they are both on Terra. We'd need to pick a reference frame closer to home, where Artemis 2 is now stationary and Ted continues to move. WGS-84 is the obvious choice, I think. I suspect Ted is already being measured in it. I *definitely* wouldn't pick one with a billionaire as the origin point. The billionaire hopping onto a private (or even public) jet would make it seem like Artemis 2 was moving once again. Aside from complicating what is already a non-inertial frame, this seems like cheating to keep raising Artemis 2's total. (-: Artemis 2 does get legitimate credit for a few thousand extra km, though, because the service module took its own path around the globe after separation from the crew module. @GetCarter@mastodonapp.uk #astronomy #physics #GNSS #GPS
