In this edition of the PhysicsCentral podcast, we hear from a few teams who are still in the running for the CubeQuest Challenge: a contest for homegrown teams to build their own small satellites - cubesats - and compete against each other by demonstrating technological feats. Five million dollars in prize money will be divided among teams who can get into orbit around the moon, maintain a stable orbit for a long time, or make it almost all the way to Mars' orbit while still communicating with Earth.
