TheTethered Experiment for Mars inter-Planetary Operations (TEMPO3) is a proposedCubeSat-basedsatellite[1] meant to demonstratecentripetal artificial gravity generation. After launch, the spacecraft will spin end over end to create gravity-like acceleration at both ends of a tether.[2] The project is being run by theMars Society. It aims building from high-altitude tests to eventual orbital flight. Status is unknown since 2012.
In theMars Direct architecture for a humans-to-Mars mission, the crew on their way toMars uses their discarded upper stage as a counterweight to spin end over end. This action generates gravity for the crew and prevents them from having to spend the six-month trip in zero-gravity conditions.Gemini 11 and12 showed that the concept was viable,[3] but no gravity-related work has taken place since then using tethers.
TEMPO3 was selected as the winner of theMars Project Challenge, run by theMars Society in 2008, to determine the group's next major project.[4]
The spacecraft will launch with otherCubeSat satellites. After separating from its carrier, TEMPO3 will spin up and then split into two parts connected by a tether. Separating will slow the spin rate, but will increase the acceleration measured at the ends. Accelerometers on board the spacecraft will sense the amount of gravity being demonstrated and will beam that data to Earth.[5]
