Hisaki ( Japanese ひ さ き ), project name SPRINT-A (Spectroscopic Planet Observatory for Recognition of Interaction of Atmosphere), is a space telescope from the Japanese JAXA .
The satellite was named after Hi-saki ( 火 崎 , literally "Cape of Fire") a cape on the Tsushiro Peninsula near the launch site that fishermen use to pray for a safe voyage, and its wedge shape to the appearance of the satellite remind. In addition, the name refers to the fact that the target objects are in front of or beyond (Japanese saki ) the sun (Japanese hi ).
It was launched into elliptical orbit on September 14, 2013 at 05:00 UTC by an Epsilon launcher from the Uchinoura Space Center rocket launch site .
The three-axis stabilized satellite is equipped with two telescopes with sensors for the extreme ultraviolet range and is intended to examine the atmospheres and the surroundings of planets such as Venus , Mars and Jupiter . The aim is to observe the interaction of the solar wind with the outer layers of the atmosphere and to draw conclusions from the data about the extensive expansion of Jupiter's magnetic field . For comparison, the environment of the planets Mars and Venus, which largely lack a magnetic field, will also be examined. It was built on the basis of the Jaxa Sprint series and has a planned service life of one year.
