TRICOM-1R
TRICOM-1R, also known as Tasuki (COSPAR 2018-016A, SATCAT 43201), was a Japanese nanosatellite that was launched during the SS-520-5 sounding rocket test launch on 3 February 2018, with a mission to conduct store and forward data relay and Earth observation using a set of cameras. Developed by the University of Tokyo, the spacecraft was a low-cost 3U CubeSat, with a goal of realizing future cost-competitive nanosatellites in the global market by using domestic commercial products. TRICOM-1R decayed from orbit 21 August 2018. Overview TRICOM-1R was built based on the 'Hodoyoshi Reliability Engineering' demonstrated by the Hodoyoshi 3 and 4 microsatellites. It was built by the University of Tokyo Intelligent Space Systems Laboratory, with funding allocated from the Japanese Ministry of Economy, Trade and Industry. The store and forward mission involved the satellite storing weak signal data from terrestrial terminals, and forwarding the data when the satellite flies above ground stations. TRICOM-1R also conducted Earth observation using its main camera and five sub cameras. The name of the spacecraft was partially based on the Japanese word , which means 'to take in', due to the store and forward nature of the mission. Launch TRICOM-1R was successfully placed into orbit on 3
