The Huygens probe has landed successfully on Saturn’s moon Titan. Congratulations are in order to the European Space Agency (ESA) who built Huygens and to NASA who launched, and delivered Huygens via the Cassini orbiter. Huygens is now in communication with Cassini orbiter for later transmission to Earth.
Huygens landed and is transmitting telemetry! So it didn’t land hard, fortunately. But what do you think it landed on? Mud? Liquid? Rock? Or an unfortunate Titanian?
