MarCO: flight results from the first interplanetary CubeSat mission

On November 26, 2018, the MarCO spacecraft successfully flew by Mars while relaying entry-descent-and-landing telemetry for the InSight vehicle. Both spacecraft performed beyond expectations and were able to provide a realtime link for the so-called ”seven minutes of terror”. In addition, once InSight safely landed, it transmitted its first image of the Martian surface through MarCO. Over the following weeks, images of Mars and Phobos, performance and health information of the spacecraft, and historical data were all downlinked.
