PRISM (Hitomi)
PRISM (Hitomi)
PRISM (Picosatellite for Remote-sensing and Innovative Space Missions), also known as Hitomi, is a technology pathfinder mission of ISSL (Intelligent Space Systems Laboratory) at the University of Tokyo (UT), Japan, to serve as a first attempt at applying nano-satellites to practical missions.
PRISM's mission is to:
- To conduct technical experiments on Ground Image Acquisition using a refracted optical system with an extensible boom (expected resolution of 10 m to 30 m)
- To conduct technical experiments and demonstrate a nano-satellite bus using commercial off-the-shelf (COTS) parts
- To perform various services and experiments for the amateur radio community
PRISM was launched in January 2009 as a piggy-back payload on an H-2A-202 rocket. By 2014, it was still active.
