Mission:

• The Japanese SELENE moon probe, Kaguya, was launched from Tanegashima spaceport on Sep 14. Planned orbit was 281 x 232805 km x 29.9 deg; later manoeuvres by the probe will raise the apogee to lunar distance.
• The Okina (R-Star) subsatellite was ejected into a 115 x 2399 km orbit at 0036 UTC on Oct 9, and the Ouna (VRAD) subsatellite was ejected at 0428 UTC on Oct 12 into a 127 x 795 km orbit.
• Japan's small Ouna spacecraft was in low lunar orbit in 2009.
• Jan 2010: Jun Takei reports that the Ouna spacecraft stopped operating on 2009 Jun 29 at 1208 UTC. Because of Ouna's low orbit around the Moon, Ouna will impact the lunar surface during 2010.
