Milstar (Military Strategic & Tactical Relay), DFS (Development Flight Satellite) is the tactical and strategic multiservice satellite system designed to provide survivable communications for U.S. forces worldwide. The program is managed by the U.S. Air Force Space and Missile Center.
Geostationary OrbitThe Vehicle Evaluation Payload (VEP), renamed Myojo after launch, was a Japanese spacecraft that provided a ranging function as well as functions to measure the acceleration and deformation, in order to confirm the accuracy of the H-2 rocket orbit injection and understand the environment of the payload equipment. The Orbital Re-entry Experiment (OREX), renamed Ryusei after launch contributed to HOPE development by accumulating experience in designing and producing a re-entry vehicle and acquiring re-entry data which is difficult to acquire in ground experiments.
Low Earth OrbitSTS-60 was the first mission of the US/Russian Shuttle-Mir Program, which carried Sergei K. Krikalev, the first Russian cosmonaut to fly aboard a Space Shuttle. The mission used Space Shuttle Discovery, which lifted off from Launch Pad 39A on 3 February 1994 from Kennedy Space Center, Florida. The mission carried the Wake Shield Facility experiment and a SPACEHAB module into orbit, and carried out a live bi-directional audio and downlink link-up with the cosmonauts aboard the Russian space station Mir.
Low Earth OrbitThe DSPSE (Deep Space Program Science Experiment), the first of a series of Clementine technology demonstrations jointly sponsored by the Ballistic Missile Defense Organization (BMDO) and the National Aeronautics and Space Administration (NASA), launched in early 1994. Its principal objective is to space qualify lightweight imaging sensors and component technologies for the next generation of Department of Defense (DoD) spacecraft. The Clementine mission uses the Moon, a near-Earth asteroid (1620 Geographos), and the spacecraft's Interstage Adapter (ISA) as targets to demonstrate lightweight component and sensor performance.
