Abstract

The deep space exploration technology demonstrator DESTINY+ has been proposed by JAXA as a publicly-acquired small spacecraft launched by an Epsilon rocket. DESTINY+ will accelerate by using Ion Engine System (IES) to increase the orbit altitude in a spiral orbit to do the lunar swing-by. After leaving Earth's gravitational sphere, DESTINY+ will reach the asteroid (3200) Phaethon via interplanetary navigation and conduct flyby observations. During the extended elliptical orbit around Earth, IES needs to be operated under the sunlight-exposed condition. Hence, the thermal design to control the temperature of equipment should be required under the sunlight-exposed condition. This paper describes details of the thermal design using a loop heat pipe for the ion engine system during exposure to sunlight. It was confirmed that IES thermal degin reqirements were satisfied using for 100W-class LHPs.
