The Bell Aircraft Company offered a proposal to the Wright Air Development Center for a manned bomber-missile, known as Bomi.

Cuba invaded at Bay of Pigs by an estimated 1,200 anti-Castro exiles aided by U.S.; invasion crushed

At a mechanical systems meeting at MSC, customer and contractor achieved a preliminary configuration freeze for the LEM. Several features of the design of the two stages were agreed upon:

Descent

four cylindrical propellant tanks (two oxidizer and two fuel); four- legged deployable landing gear

Ascent

a cylindrical crew cabin (about 234 centimeters (92 inches) in diameter) and a cylindrical tunnel (pressurized) for equipment stowage; an external equipment bay.

The VVS General Staff issues a decree discharging Nelyubov, Anikeyev, and Filatyev from the cosmonaut corps.

Grumman conducted manned drop tests to determine the LEM crew's ability to land the spacecraft from a standing position. All tests were run with the subject in an unpressurized suit in a "hands off" standing position with no restraint system or arm rests.

Despite opposition, Kamanin goes ahead with his plans. The 10-day duration artificial gravity flight is planned for October 1965, with Volynov and Katys as the crew. In the first half of 1966 Beregovoi and Demin will fly the long-duration mission, and Ponomaryova and Solovyova will fly an all-female spacewalk mission. However the Americans have announced they will fly a Gemini mission for a 7 to 8 day duration by the end of the year; the Soviets may have to adjust this plan to ensure that they retain the lead in manned spaceflight. Kamanin has told the female cosmonauts of their planned flight, but also warned them there is serious opposition in some quarters.

High resolution photo reconnaissance satellite; returned film capsule; also carried weather experiments.

Last Emergency Rocket Communications Satellite test

Soft landed on Moon; perrformed soil sample tests and imaged lunar surface.

KH-8 type satellite. Space craft engaged in investigation of spaceflight techniques and technology (US Cat A).

Glide. Maximum Speed - 763 kph. Maximum Altitude - 13720 m. Flight Time - 217 sec.

3 chambers. Maximum Speed - 973 kph. Maximum Altitude - 16070 m. Flight Time - 400 sec.

NASA Hq. established an Apollo 13 Review Board to investigate the Apollo 13 accident.

About four hours before reentry on April 17, the service module was jettisoned and the crew took photographs and made visual observations of the damaged area. About one hour before splashdown the command module was powered up and the lunar module was jettisoned. Parachutes were deployed as planned, and the Odyssey landed in the mid-Pacific 6.4 kilometers from the recovery ship U.S.S. Iwo Jima at 1:07 p.m. EST (18:07 GMT). The astronauts were picked up by helicopter and transported to the recovery ship less than an hour after splashdown.

The day dawns warm at Baikonur (7 deg C at 7 am). The cosmonauts' morning is spent in a review of the space station's guidance and control systems. In the afternoon there is a briefing by officers of IAKM-VVS on use of the vacuum facility 'Polinom' during the flight. The cosmonauts are against use of the device.

Acquisition of meteorological information needed for use by the weather service.

FU200 3SUV, UV solar astronomy / Ptr mission.

High resolution photo reconnaissance satellite; returned film capsule; maneuverable.

Rohini satellite D-2. Second developmental flight of an SLV-3 launch vehicle. The Rohini satellite D-2 carried a sensor payload for conducting remote-sensing experiments and for accurate orbit and attitude determination.

KH-8 type satellite. Spacecraft engaged in practical applications and uses of space technology such as weather or communication (US Cat C).

Suborbital test of 1/8 scale model of Buran. Typical trajectory: ascent to 120 km; pitch down to drive model in atmosphere at 45 degree at Mach 18.5. None were reflown but at least 4 were recovered.

Replaced Cosmos 1503.

Military cartographic satellite; returned film capsule.

STS-56 landed at 11:40 GMT.

Military navigation satellite. Positioned in plane 2 of constellation. Signals at 149.91 and 399.76 MHz.

Installation of the new VDU station orientation engine assembly was completed at the end of the Sofora boom.

Columbia rolled out to pad 39B on March 23. Payloads:

• Spacelab transfer tunnel
• Spacelab Long Module, with Neurolab experiments for the following life science studies:
  • Chronic Recording of Otolith Nerves in Microgravity
  • Development of the Aortic Baroreflex under Conditions of Microgravity
  • Neural-Thyroid Interaction on Skeletal Isomyosin Expression in OG
  • Spatial Orientation of the Vestibulo-Ocular Reflex and Velocity Storage
  • Autonomic Neuroplasticity in Weightlessness

• Extended Duration Orbiter pallet
• Two Get Away Special beams with canisters G-197, G-467, G-772 (Colorado's COLLIDE experiment, which collided small particles into each other to simulate the formation of planets and rings).

The Neurolab mission was managed by NASA-Johnson at Houston, unlike earlier Spacelab flights which were NASA-Marshall/Huntsville's responsibility. Landed at Kennedy Space Center May 3 1998.

Sesat (Siberia-Europe Satellite) used an MSS-2500-GSO (Gals/Ekspress) satellite bus built by NPO PM of Krasnoyarsk, with an Alcatel Espace France payload of 18 Ku-band transponders. The satellite had 8 Fakel SPD-100 plasma thrusters for stationkeeping. Eutelsat operated their Hot Bird fleet of European television broadcast satellites since the 1980's, but the venture into broadcasting to Siberia represented a new step for them. Stationed at 36 deg E. Positioned in geosynchronous orbit at 39 deg E in 2000. As of 4 September 2001 located at 35.97 deg E drifting at 0.005 deg E per day. As of 2007 Mar 9 located at 35.92E drifting at 0.004E degrees per day.

MAST consisted of the TED (Tether Deployer) satellite, with a 1 km deployable multi-strand Hoytether; RALPH, a small end mass satellite; and between them, GADGET, an inspector satellite which could move along the tether. Before deployment the MAST package fit into a 0.3 m x 0.1 m module.
