MarCO (or Mars Cube One) was a Mars flyby mission launched alongside NASA's InSight Mars lander mission. It consisted of two 6U-sized cubesats, MarCO-A and MarCO-B, that provided a real-time communications link to Earth for InSight during its entry, descent, and landing - when InSight was out of line of sight from the Earth.
