Description

The relay subsatellite is an octagonal cylinder 0.99 x 0.99 x 0.65 m in size with a mass of 53 kg. A dipole antenna protrudes from the top center of the subsatellite and four small S-band patch antennas are mounted on the spacecraft, two on the top deck and two on the bottom.

The spacecraft is spin-stabilized at 10 rpm and has no propulsion units. Power is provided by a 70 W Si solar cell array covering the sides of the satellite which charges a 13 AH, 26 V NiMH battery. The relay subsatellite contains one X-band and three S-band VLBI radio sources and a transponder and will relay the 4-way Doppler ranging signal between a ground station and the orbiter for the far side gravity field investigation from a 100 x 2400 km orbit.

Okina impacted the Moon on 12 February 2009.

Launch Date: 14 September 2007, 01:31:01 UT

Function: Global survey of the Moon.

Description

The primary objective of the mission is a global survey of the Moon, obtaining data on elemental abundance, mineralogical composition, topography, geology, gravity, and the lunar and solar-terrestrial plasma environments and to develop critical technologies for future lunar exploration, such as lunar polar orbit injection, three-axis attitude stabilization, and thermal control.

The mission consists of three satellites, an orbiter containing most of the scientific equipment, a VLBI (Very Long Baseline Interferometry) Radio (VRAD) satellite, and a relay satellite designed to receive a doppler ranging signal from the orbiter when it is around the far side out of direct contact wth the Earth and transmit the signal to Earth to estimate the far-side gravitational field.
