"The Naval Research Laboratory supported the 8th Annual CanSat competition where 26 college rocket teams came together from all over the world to compete. This year's "mission" was to launch an autonomous CanSat (a satellite in a can) with a deployable lander containing one large raw hen egg that cannot be damaged on landing. The "CanSat " refers to the complete system-the carrier and the lander. The event was held on June 8-10, 2012, in Abilene and Burkett, Texas.
The CanSat is deployed from a rocket at an altitude of about 610 meters (2001 feet). Once released from the rocket, the CanSat descends between 10 and 20 meters per second using any type of descent control system or device. At an altitude of 200 meters, the CanSat reduces the descent rate to within 4 and 6 meters per second. At 91 meters altitude, the CanSat carrier releases the lander that contains one large raw hen's egg. The lander hopefully lands without damaging the egg. The lander cannot free fall. It must contain a descent control system or device to reduce the descent rate to less than 5 meters per second. The carrier telemetry data may be stored on-board for post processing in the event of a communications failure. Teams must build their own ground station. Telemetry from the carrier is displayed, in real-time, on a team-developed ground station." More.
