Army Jupiter IRBM was fired 1,500 miles, limit of its designed range, and to an altitude of 250-300 miles, the first successful launching of an IRBM. Fired from AMR at 1308 hours EST to test the range capability and performance of rocket engine and control system. Although the missile was 253 nm short of its estimated 1,400 nm impact point, this was the first successful flight of the Jupiter. All phases of the test were successful during this first firing of the IRBM in the western world References: 439 .

Landed far from aim point.

NASA selected Rocketdyne Division of NAA to develop the J-2, a 200,000-pound-thrust rocket engine, burning liquid hydrogen and liquid oxygen. (A decision was later made to use the J-2 in the upper stages of the Saturn C-5.) References: 16 .

Mir module; materials processing laboratory. Docked with Mir. Kristall: Mass: 19,500 kg. Mass on docking 17,200 kg. Length: 11. 9 m or 13. 73 m?. Solar array span 36 m. Diameter: 4. 35 m. Payload: 7,000 kg. Two compartments. Instrument-Payload Compartment contains food containers, and industrial processing units Krater 3, Optizon 1, Zona 02, and Zona 03. 0. 8 m hatch leads to Junction-Docking compartment. This contains spherical universal docker with two APAS-89 androgynous docking units. These will be used to dock with Buran shuttle and 1,000 kg X-ray telescope to be delivered by Buran in 1991. Third opening houses earth observation cameras.
Launch originally planned for 30 March 1990. Delayed to April 18, then further delayed due to computer chip problems.
Launched 31 May 1990 12:33 GMT. Docking scheduled June 6 at 12:36 but delayed due to problem with one of Kristall's orientation engines. Docking successful 10 June at 12:47. On June 11 moved to side port. Work within module began 15 June.
Spektr: Late 1991 launch. Remote sensing work. Occupies port opposite Kvant 2. Before this occurs Kristall solar arrays will be relocated to Kvant.
