SOCRATES or Space Optical Communications Research Advanced Technology Satellite^[1] is a Japanese micro-satellite launched in 2014. The satellite is purely a technology demonstrator intended to help AES company to gain experience in basic mission control, attitude control and spacecraft communications. It does not have any dedicated payload instruments. All subsystems of spacecraft are powered by solar cells mounted on spacecraft body and stub wings, with estimated electrical power of 120W BOL degrading to 100W EOL.

Launch

SOCRATES was launched from Tanegashima, Japan, on 24 May 2014 by a H-IIA rocket.
