In case you missed it, NASA has announced that in 2016 there will be two small MarCO CubeSats that will be flying past Mars, just as InSight is descending on the surface. InSight is the name of the next Mars lander.

These are a pair of briefcase-sized CubeSats, called Mars Cube One or MarCO, whose function is merely to quickly relay landing data back to NASA. While they will have no impact of the success of the mission, it once again shows the growing versatility and usefulness of CubeSats!
