Psyche mission launched on October 13, 2023, with the goal of exploring the origin of planetary cores and studying the metallic asteroid known as 16 Psyche. The spacecraft is scheduled to reach the namesake asteroid in 2029.

minus-squareiegod@lemm.eelinkfedilinkarrow-up3·7 months agoActually, it is! Space motion isn’t straightforward. Here’s another article that has a diagram indicating the relative positions. https://www.jpl.nasa.gov/news/nasas-optical-comms-demo-transmits-data-over-140-million-miles
minus-squareMango@lemmy.worldlinkfedilinkarrow-up2·7 months agoOh wow thanks! I did not have the perspective for the distance. I figured that was Voyager 1 kind of numbers.
