Occurred 5 years ago
Type
CubeSat
Launch
May 5, 2018
Target
Mars
Objective
Technology Demonstration, CubeSat/SmallSat
Mars Cube One (MarCO) was the first interplanetary mission to use a class of mini-spacecraft called CubeSats. Their goal was to test new miniaturized deep space communication equipment. Upon their arrival at Mars, the twin MarCOs successfully relayed back InSight data as it entered the Martian atmosphere and landed.
