Saenger's Experiment Number 25 is the first to successfully sustain combustion. The water-cooled combustion chamber sustains an internal pressure of 15 atmospheres for 30 seconds.

The cause of early detonation of the warhead during the engine burn time is understood, but the crashes at the end of the trajectory are still a mystery. Dornberger is ordered to report to Hitler at Berchtesgaden. The call is received at 7 pm in the evening, following a bomb raid and ice storm. Dornberger is told that on the following morning Von Braun, Riedel II, and Groettrup are to be arrested for sabotage of the A4 program. Groettrup selects Dr Steinhoff as his representative. The men are accused of not putting all their energy in development of the A4 as a weapon - instead only using the financing of the Reich to support their private plans for manned spaceflight. Dornberger know he cannot complete the program without these men - Von Braun and Riedel were the key leaders, and Groettrup was head of the electrical systems section. Dornberger finally achieves their release by demonstrating to the SS that the biggest impediment to the program was Hitler's dream that the A4 would never reach London. After a few days in detention, Von Braun was moved to Schwedt, and then freed. The others were allowed out a bit later.

Launched from Toulon, France. Intended to take a 25 kg payload to 100 km altitude, the rocket instead veered off course and crashed after 5 seconds of flight.

First American-assembled V-2 static fired at White Sands Proving Ground.

Unsuccessful. First Phase I trials launch of the 8 remaining rockets of the first production lot were fired, of which 6 reached the target area. The first launch was on 15 March 1953. The first successful flight was on 2 April 1953. The first full range flight came on 19 April 1953.

The first Jupiter A launching, by ABMA at Cape Canaveral. RS-18 was launched at 1936 hours EST from AMR. The flight was successful. The scheduled launching date of this missile was 13 March. Three holds were called because of LOX difficulties, telemetry difficulties, and replacement of a gate valve. The actual range was 133.58 nm; 10.3 nm under; and 5.66 nm right of the intended impact point. Separation occurred before the missile gained its correct velocity. Improper assumption of propellant flow for the trajectory calculation was primarily responsible for the incorrect cut-off. The primary test objectives were to test the complete guidance and control system to establish the performance qualities of the complete missile system. Missed aimpoint by 19,100 m.

The Army Ballistic Missile Agency's Development Operations Division and the Saturn program were transferred to NASA after the expiration of the 60-day limit for congressional action on the President's proposal of January 14. (The President's decision had been made on October 21, 1959.) By Executive Order, the President named the facilities the "George C. Marshall Space Flight Center." Formal transfer took place on July 1.

Successful missile test with T-1 Capsule. Missed aimpoint by 295 m.

United States and United Kingdom signed formal agreement covering Mercury tracking stations on Bermuda.

NASA Headquarters publicly announced that Scott Carpenter would pilot the Mercury-Atlas 7 (MA-7) manned orbital mission replacing Donald Slayton. The latter, formerly scheduled for the flight, was disqualified because of a minor erratic heart rate.

The Zenit-4 fitted with the airlock attachment ring successfully lands at 12:09, 170 km south of Kustanin (and 50 km north of the aim point). Later procedures for emergency landing on the first, second, and third orbits are discussed. The cosmonauts want to discuss the possibility of their taking action if the airlock fails to jettison (even though there are redundant systems to ensure this). Leonov discuses a method of inflating the airlock, his opening the hatch from the spacecraft, checking all connections, then returning to the capsule and attempting again. Data arrives in the evening from the recovered Zenit - the rotation rates are acceptable, Voskhod-2 is clear to launch on 18 March. In the evening the cosmonauts conduct interviews with journalists.

The State Commission meets on the 21st day of flight. The life forms are still alive, although the atmosphere in the cabin isgradually worsening (oxygen has gone from 143 to 136 mm Hg and the carbon dioxide level has gone up from 0.89% to 0.91%). The flight duration objective has been fulfilled, and although the designers say the ECS could run for a total of 36 days, it is decided to bring the capsule down within the next two days. A landing commission of 25 military and engineering representatives is formed to oversee the process. It is decided to bring the capsule down on the 330th orbit, on 16 March, with an emergency re-entry possible at 15:30 on 15 March if the cabin parameters worsen.

CIA reports accurately development of N-1, Almaz, Proton, etc.... even states 100,000 kg large space station in development for launch by N-1 by 1969. CIA does not expect lunar landing until early 1970's.

Military-Industrial Commission (VPK) Decree 42 'On search service for returning missions from the Moon' was issued.

Maximum Speed - 684 kph. Maximum Altitude - 13720 m. Flight Time - 243 sec.

High resolution photo reconnaissance satellite; returned film capsule

Definition studies for a second Orbital Workshop (Skylab II) were under study. Mission objectives would respond to the following major objectives: continued development and expansion of the ability to live, work, and operate effectively in space; exploitation of space for practical benefits through the observation of Earth and its environment; and the use of space for scientific research.

The third, back-up DOS crew of Dobrovolsky, Volkov and Patsayev train in the DOS trainer. All of the crews have made good runs, with no mistakes or failures. Shatalov, after training on the DOS simulator, now supports Mishin's 30 day flight approach. He has also talked to Yeliseyev and Sevastyanov about the matter. He believes there may be a very different reaction to zero-G from individual to individual, and the Soyuz 9 crew may have been the wrong two individuals.

NASA decided that the shuttle booster will be 2 x 156 inch solid rocket motors. This would reduce the total development cost by $700 million, from $ 5.85 billion to $ 5.15 billion. It was also decided to delete the requirement for the shuttle to be equipped with air-breathing engines for final approach and ferry, and to add Abort Solid Rocket Motors that would pull the shuttle away from the external tank in case of a failure of the solid rocket boosters or external tank during the first portion of the ascent to orbit.

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

A Lunar Programs Office, under which the Lunar Data Analysis and Synthesis Program would be conducted, was established in the Office of Space Science, NASA Hq. The office was responsible for continued operation and collection of data from the Apollo lunar surface experiment packages and the Apollo 15 subsatellite; Apollo surface and orbital science data analysis by principal investigators; development of selenodetic, cartographic, and photographic products; continued lunar laser ranging experiment; continued lunar sample analysis; lunar supporting research and technology; and advanced program studies.

From March-October 1985 the Ts core stage was back on the UKSS test/launch stand for cold flow tests. A total of nine cryogenic fuelling cycle were completed with the 4M Energia mock-up, representing the first operational use in the world of super-chilled hydrogen.

Telescopic boom installed.

In the second Soyuz/Ikar launch four Globalstar satellites were delivered with the Ikar upper stage into a 235 km x 899 km x 52.0 degree transfer orbit. The Ikar stage then placed itself and its payload into a 897 km x 950 km x 52.0 degree deployment orbit. Satellite M022 was separated first from the top of the dispenser, followed by ejection of the other three satellites from the sides at 06:37 GMT. After dispensing the satellites, the Ikar deorbited itself on March 16.
