OMOTENASHI @ Nanosats Database

Name	OMOTENASHI
Type	CubeSat
Units or mass	6U
Status	Was semi-operational until 2022-11-17, 1 day (Connection was established as per official Twitter but low voltage and attitude control issues lead to transmitter being turned off as of 2022-12-23)
Launched	2022-11-16
NORAD ID	? (Not yet catalogued and tracked?)
Deployer	CSD (Canisterized Satellite Dispenser) [Planetary Systems Corporation]
Launcher	SLS (Space Launch System) (Artemis-1)
Organisation	University of Tokyo
Institution	University
Entity	Academic / Education
Nation	Japan
Oneliner	Demonstrate the technology for low-cost and very small spacecraft to explore the lunar surface with a landing probe.
Description	3 modules: orbiting module, retro motor module, and surface probe. Demonstrate the technology for low-cost and very small spacecraft to explore the lunar surface. This technology could open up new possibilities for future missions to inexpensively investigate the surface of the moon. The CubeSat will also take measurements of the radiation environment near the moon as well as on the lunar surface. Super-Small Solid Rocket Motor to deaccelerate 2500 m/s just before surface impact. Surface probe will have a semi-hard landing at about 50 m/s.
Failure cause	Spacecraft was rotating rapidly and solar cells were opposite direction to the Sun. Transmitter turned off at the end of the pass due to low voltage and has not restored.
