During the previous three years, at a total cost of $ 2,000, Goddard had developed a rocket-propelled depth charge and anti-ship missile with an armour-piercing warhead. The Navy sees no future potential in the work.

After the military success in Poland, Hitler believes development of expensive 'wonder weapons' are unnecessary to win the war. The A4 and other rocket projects are removed from the priority list, making acquisition of necessary materials and engineers difficult.

The Army Air Forces established Project RAND, which in part included the study of satellite applications.

Launched 16:10 local time. Reached 5.5 km. Carried Magnetic field, composition, winds, temperature (Signal Corps Engineering Lab, University of Michigan) experiments for General Electric.

Dr. Alan T. Waterman of the National Science Foundation presented President Dwight Eisenhower with a plan to implement the United States' portion of the International Geophysical Year satellite experiment.

Night airglow research. Launched at 2300 local time. Reached 114.3 km.

Deputy Secretary of Defense Quarles announced that three atomic blasts were secretly fired in space (Project Argus) in 1958, using modified X-17 rockets.

United States-Spanish agreement on Project Mercury tracking station in Canary Islands was announced (1 of 16 similar agreements with other nations).

James A Chamberlin was reassigned from Manager of Project Gemini to Senior Engineering Advisor to Robert R Gilruth, Director of Manned Spacecraft Center. Charles W Mathews was reassigned from Chief, Spacecraft Technology Division, to Acting Manager of Project Gemini.

George E. Mueller, NASA Associate Administrator for Manned Space Flight, informed Associate Administrator Robert C. Seamans, Jr., that the launch vehicle 'no longer appears to be the pacing item in the Gemini program.'

Also known as Explorer S-66.

On re-entry the primary automatic retrorocket system failed. A manually controlled retrofire was accomplished one orbit later (evidently using the primary engine, not the backup solid rocket retropack on the nose of spacecraft). The service module failed to separate completely, leading to wild gyrations of the joined reentry sphere - service module before connecting wires burned through. Vostok 2 finally landed near Perm in the Ural mountains in heavy forest at 59:34 N 55:28 E on March 19, 1965 9:02 GMT. The crew spent two nights in deep woods, surrounded by wolves. Recovery crews had to chop down trees to clear landing zones for helicopter recovery of the crew, who had to ski to the clearing from the spacecraft. Only some days later could the capsule itself be removed. - Additional details.

Ministry of General Machine Building (MOM) Decree 88 'On use of liquid hydrogen in the space program' was issued.

KH-4A. Due to abnormal rotational rates after revolution 22, the mission was terminated after a total of three days collecting photography.

Radar monitoring.

First powered flight. Maximum Speed - 919 kph. Maximum Altitude - 13533 m. Flight Time - 424 sec.

Leonov is going on a propaganda tour to Japan, and Shatalov to Cuba.

The VVS insists that the Soyuz 10 crew land in daylight. Mishin says that in order that the crew can land in daylight at the end of the 30-day mission, the spacecraft must be launched at 03:00 at night. Kamanin believes this also to be unsafe.

Consideration was being given to the feasibility of a second set of Skylab missions (designated Skylab-B) during the interval between the Apollo-Soyuz Test Project in 1975 and the start of Space Shuttle operations late in 1979. The inherent worth of a Skylab-B was recognized, but officials were reluctant to recommend it, on the premise that it would be unwise to allow it to delay or displace the development of the Space Shuttle and other programs already included in the FY 1974 budget.

Continued operation of the long-range telephone and telegraph radio-communication system within the Soviet Union and transmission of USSR central television programmes to stations in the Orbita and participating international networks (international cooperation scheme).

Unmanned supply vessel transporting sundry cargoes to the Mir orbital station. Docked with Mir on 21 Mar 1986 11:16:02 GMT. Undocked on 20 Apr 1986 19:24:08 GMT. Destroyed in reentry on 21 Apr 1986 00:48:30 GMT. Total free-flight time 2.27 days. Total docked time 30.34 days.

Stationed at 85 deg E. Provision of telephone and telegraph radiocommunications and television broadcasting. Positioned in geosynchronous orbit at 85 deg E in 1987-1991 As of 30 August 2001 located at 6.40 deg W drifting at 15.515 deg W per day. As of 2007 Mar 10 located at 6.61W drifting at 15.520W degrees per day.

Unmanned resupply vessel to Mir. Attempted to dock with Mir on 21 March 1998 14:28 GMT, but missed the station by 500 m. Docking attempted again on 23 March but at 50 meters the docking was aborted; the Progress missed hitting the station by five meters. Thereafter it was placed in a station-keeping co-orbit with Mir while the problem was diagnosed. Finally docked with Mir on 28 Mar 1991 12:02:28 GMT. On 12 and 14 Apr 1998 two burns of the engine of Progress M-7 raised the station's orbit from a 360 x 377 km orbit to a 370 x 382 km orbit. Undocked on 6 May 1991 22:59:36 GMT. Destroyed in reentry on 7 May 1991 17:20:05 GMT. Total free-flight time 9.72 days. Total docked time 39.46 days.

Radar calibration mission.

Chinese papers at the meeting sketched details of future planned missions. China was likely to begin its manned flights with a single orbit around Earth, and later launch its lunar 'quest'. Existing Chinese launchers had the capability to send scientific devices, but not humans, to the moon -- it could take up to eight years to design a lunar spacecraft. Feasibility studies on trips to the moon and Mars had begun. Participants called for greater international cooperation in space and the lifting of an apparent freeze on China's participation in major joint projects. They resented China's exclusion from the International Space Station.

The Expedition 4 crew finished loading the Progress M1-7 craft, and it undocked from Zvezda's aft port at 1743 UTC. The Kolibri-2000 microsatellite was ejected from the Progress cargo compartment at 2228 UTC; Progress fired its engines to deorbit over the Pacific at about 0127 UTC on Mar 20.

Placed in orbital slot 99.2° W Longitude. In combination with DirecTV 10, the satellite would allow the parent company to direct broadcast local HDTV to 90 percent of its customers in North America. The Ka-band satellite was equipped with 28 active and 8 spare TWTAs for direct broadcast to the continental United States and Alaska; 4 active and 4 spare for broadcast to the 48 stages and Hawaii; and 55 active and 15 spares for spot transmissions. Total power was 18 kW / 16 kW at beginning/end of life. Propulsion was provided by 445 N liquid apogee engine and four XIPS 35-cm ion thrusters. Mass at launch was 6060 kg and 3700 kg after on-board propellants were consumed to place the satellite in its operational geosynchronous orbit.
