Hisaki

NSSDCA/COSPAR ID: 2013-049A

Description

Hisaki (known as SPRINT-A prior to launch) is a space telescope that remotely observes Venus, Mars, Jupiter and other planets from Earth orbit. It is designed to observe in the extreme ultraviolet (EUV) to study the plasma region surrounding the Jovian satellite Io to determine how energy is provided to the torus. It will also investigate the mechanism of how the atmospheres of Venus and Mars has escaped to space.

The mission payload contains an EUV spectrometer, and a guiding camera which maintains the pointing accuracy of the mission. EXCEED employs a new standard and flexible satellite bus module developed for the series in JAXA.

This mission replaced the cancelled TOPS satellite. It was launched on the maiden flight of the Epsilon launch vehicle.
