MarCO, short for Mars Cube One, demonstrated the ability of small satellites to explore deep space and provided real-time information in support of critical landing operations on a distant world.
- The MarCO twins — nicknamed EVE and WALL-E, after characters from a Pixar film — provided an experimental communications relay to inform Earth quickly about the landing.
- MarCO A and B successfully completed their mission as communications relay satellites for the InSight Mars landing on Nov. 26, 2018. The spacecraft will end up in orbit around the Sun. WALL-E was last heard from on Dec. 29; EVE, on Jan. 4.
- The two briefcase-size MarCO CubeSats launched with the InSight lander on an Atlas V rocket from Vandenberg Air Force Base in California.

Spacecraft Mass: The basic CubeSat unit is a box roughly 4 inches (10 centimeters) square. Larger CubeSats are multiples of that unit. MarCO's design is a six-unit CubeSat - about the size of a briefcase -- with a stowed size of about 14.4 inches (36.6 centimeters) by 9.5 inches (24.3 centimeters) by 4.6 inches (11.8 centimeters).
