STEP CUBE LAB

Informationen über STEP CUBE LAB

Verify core space technologies researched in universities and industries, and verifying those technologies on-orbit.  To determine which of the fundamental space technologies researched at domestic universities, will be potential candidates for use in future space missions and to verify the effectiveness of the technologies by investigating mission data obtained from on-orbit operation of the cube satellite. The payloads to be verified in the STEP mission are a variable emittance radiator, an oscillating heat pipe, a MEMS based solid propellant thruster, a concentrating photovoltaic (CPV) power system, and a novel non-explosive holding and release mechanism triggered by nichrome burn wire heating.
