Raijin-2

Raijin-2 (Rising-2) is a Japanese micro-satellite launched in 2014. The satellite is built around a 10 cm diameter, 1m focal length Cassegrain telescope and features the following instruments: All instruments are powered by GaAs solar cells mounted on the spacecraft body, with estimated electrical power of 47.6W. The spacecraft features an unusual central-pillar bus, inherited from the Sprite-Sat satellite. The attitude control is done by means of reaction wheels and magneto-torquers, and qualified for 0.1 degrees angular accuracy.
 * HPT - main telescope with 5m resolution at nadir, operating in visible and near-infrared bands
 * BOL - bolometer array camera for cloud temperature measurement
 * WFC - wide field-of-view CCD camera
 * LSI-N and LSI-W - 2 CMOS medium field-of-view cameras for near-infrared imaging
 * VLF-ANT, R - radio antenna to receive signatures of lighting events

Launch
RISING-2 was launched from Tanegashima, Japan, on 24 May 2014 by a H-IIA rocket.

Mission
The satellite is intended for atmosphere research, especially for gathering statistics on cloud formation and the occurrence of sprites in the upper atmosphere. Mission data are down-linked in S-band with maximal data rate of 38.4 kbit/s.
