Mission Demonstration Satellite 1 (MDS-1) or Tsubasa (COSPAR 2002-003A, SATCAT 27367) was a
Japanese technology test mission. It was launched by the second
H-2A on February 4, 2002 from the
Tanegashima Space Center. After the launch, MDS-1 was renamed Tsubasa, meaning wings in
Japanese.[1] Tsubasa was placed in a
geostationary transfer orbit (GTO). It ended its operational phase on 26 February 2003.[2] A similar mission, MDS-2, was cancelled.[3]
