OMOTENASHI Project Shoots for the Moon This Week
OMOTENASHI, a project of the JAXA Ham Radio Club, is a CubeSat which will be launched by NASA SLS rocket, scheduled for August 29. It plans to land on the surface of the moon, and to transmit a beacon in the amateur 70cm band.
OMOTENASHI is one of the EM-1 CubeSat missions which will be launched by the NASA/SLS rocket (EM-1) together with the main mission of ORION experimental module on Monday. JAXA Ham Radio Club is going to utilize the flight demonstration opportunity of the OMOTENASHI mission to conduct the following amateur radio missions:
(i) To conduct technological research with respect to receiving ultra-weak UHF signal from a space probe toward the moon
(ii) To conduct an outreach activity providing amateur radio operators all over the world with an opportunity to try to receive signals from moon region.
OMOTENASHI is a 6U-CubeSat with external dimensions of 239 x 366 x 113mm and an approximate mass of 14 kg.
OMOTENASHI consists of three modules: orbiting module, retro motor module, and surface probe. During the moon transfer orbit, these modules are integrated. When OMOTENASHI arrives at the moon, the surface probe will be separated and conduct semi-hard landing.
OMOTENASHI is actively controlled by ultra-small attitude control system including star tracker, sun sensor, IMU, reaction wheel, and cold gas jet thruster. During the moon transfer orbit, OMOTENASHI may be spin-stabilized due to the strict resources. For further details, please see: https://www.isas.jaxa.jp/home/omotenashi/JHRCweb/jhrc.html
There will be UHF CM/PSK/PM/PSK31 beacons, with 1 watt RF, on both the orbiting module and the surface probe. CisLunar explorer, MIT KitCube and Lunar IceCube are expected to share the same launch.
