One of the Most Exciting Parts of InSight is Actually the Tiny Cubesats Tagging Along for the Ride and Their Role in the Mission

Yesterday, NASA’s Mars InSight lander successfully touched down on the Martian surface after spending seven long months in space. Over the course of the next few hours, the lander began the surface operations phase of its mission, which involved deploying its solar arrays. The lander also managed to take some pictures of the surface, which showed the region where it will be studying Mars’ interior for the next two years.

In the midst of all that, another major accomplishment received only passing attention. This was the Mars Cube One (MarCO) mission, an experiment conducted by NASA to see if two experimental CubeSats could survive the trip to deep space. Not only did these satellites survive the journey, they managed to relay communications from the lander and even took some pictures of their own.
