The Redstone missile system officially received its popular name. Previously, this missile was known at various times and places as the Hermes C1, Major, Ursa, XSSM-G-14, and XSSM-A-14.

KH-5; film capsule boosted into higher orbit, decayed 5/23/62. Mission failed. Loss of satellite control gas caused unstable condition. No recovery. Officially: Spacecraft Engaged in investigation of spaceflight techniques and technology (US Cat A).

The first Gemini mission, Gemini-Titan I, was launched from Complex 19 at Cape Kennedy at 11:00 a.m., e.s.t. This was an unmanned flight, using the first production Gemini spacecraft and a modified Titan II Gemini launch vehicle (GLV). The mission's primary purpose was to verify the structural integrity of the GLV and spacecraft, as well as to demonstrate the GLV's ability to place the spacecraft into a prescribed earth orbit. Mission plans did not include separation of the spacecraft from the second stage of the vehicle, and both were inserted into orbit as a unit six minutes after launch. The planned mission encompassed only the first three orbits and ended about four hours and 50 minutes after liftoff. No recovery was planned for this mission, but Goddard continued to track the spacecraft until it reentered the atmosphere on the 64th orbital pass over the southern Atlantic Ocean (April 12) and disintegrated. The flight qualified the GLV and its systems and the structure of the spacecraft.

Maximum Speed - 5580 kph. Maximum Altitude - 53340 m.

Deputy Administrator Robert C. Seamans, Jr., received a letter from John S. Foster, Jr., Director of Defense Research and Engineering, expressing pleasure that the agreement between the Department of Defense and NASA on extraterrestrial mapping, charting, and geodesy support had been consummated. He was returning a copy of the agreement for the NASA files.

Tyulin reveals that Voskhod 3 should be completely integrated and ready to go by the end of April, but the flight will be pushed back even farther than that. Mishin is also raising questions about Voskhod 4 and Voskhod 5. The cosmonauts are ready, but have nothing to do but wait. Who will supervise future manned space missions is in question. Korolev was de facto leader in the past. The others - the President of the State Commission, the President of the Academy of Sciences - were in fact just there in support roles. Without Korolev, this may change in the future, and the question has become controversial.

Launch vehicle test. Payload was dummy Surveyor spacecraft.

Orbiting Astronomical Observatory. Spacecraft engaged in research and exploration of the upper atmosphere or outer space (US Cat B).

Protoype Soyuz 7K-L1 manned circumlunar spacecraft. There are high winds for the L1 launch, 15-17 m/s. The official limit is 20 m/s, but Chelomei wants to scrub the launch if winds go over 15 m/s. Nevertheless the launch proceeds in 17-18 m/s winds and the L1 reached earth orbit. However the Block D translunar injection stage failed to fire (ullage rockets, which had to fire to settle propellants in tanks before main engine fired, were jettisoned prematurely). The failure is blamed on Mishin and has Tsybin seething in anger. Mishin is disorganised and has made many mistakes. Spacecraft burned up two days later when orbit decayed. Later in the day comes the news the RTS has to be replaced on one of the Soyuz 1/2 spacecraft. This will have a 3 to 4 day schedule impact, and push the launch back to 15-20 April. The crews arrive the same day for the upcoming Soyuz launch.

MiG-15UTI trainer crashes are reported from Algeria and Hungary. They are to be investigated - could they be due to some common problem that also killed Gagarin?

Environmental research. Primary experiments consisted of an image dissector camera system for providing daytime cloudcover pictures both in real-time and recorded modes, temperature-humidity infrared radiometer (THIR) for measuring daytime and nighttime surface and cloudtop temperatures as well as the water vapor content of the upper atmosphere, infrared interferometer spectrometer (IRIS) for measuring the emission spectra of the earth/atmosphere system, satellite infrared spectrometer (SIRS) for determining the vertical profiles of temperature and water vapor in the atmosphere, a monitor of ultraviolet solar energy (MUSE) for detecting solar UV radiation, a backscatter ultraviolet (BUV) detector for monitoring the vertical distribution and total amount of atmospheric ozone on a global scale, a filter wedge spectrometer (FWS) for accurate measurement of IR radiance as a function of wavelength from the earth/atmosphere system, a selective chopper radiometer (SCR) for determining the temperatures of six successive 10-km layers in the atmosphere from absorption measurements in the 15-micrometer CO2 band, and an interrogation, recording, and location system (IRLS) for locating, interrogating, recording, and retransmitting meteorological and geophysical data from remote collection stations. The spacecraft performed well until April 14, 1971, when attitude problems started. The experiments then operated on a limited time basis until September 30, 1980.

STS-83 landed at 18:33 GMT.

Launch delayed from March 22, April 4. Space Shuttle Atlantis entered an orbit of approximately 59 x 229 km x 51.6 deg at 2052 UTC, and separated from the External Tank, ET-114. ET-114 reached apogee around 2122 UTC and reentered over the Pacific about 2150 UTC at the end of its first orbit. Atlantis fired its OMS engines at apogee to raise its perigee to 155 km. Further orbit changes will lead to a rendezvous with the Space Station on Station mission 8A. STS-110 carried the S0 truss segment to the Station. The truss was the first segment of the main backbone of the Station which was to grow to carry the large solar panel wings and radiators. Cargo manifest:

• Bay 1-2: Orbiter Docking System - 1800 kg + 3 EMU spacesuits - 360 kg
• Bay 4-13: S0 Truss - 12623 kg. The S0 truss, built by Boeing/Huntington Beach, was 13.4 m long and 4.6 m in diameter. The main truss had a hexagonal cross section. One face carried fluid, power and data cables, while another face carried the rails for the Mobile Transporter. The S0 contained avionics, GPS antennae, and a radiation dose monitor. The S0 would be attached to the LCA (Lab Cradle Assembly) which was attached to the top of the Destiny lab module in 2001. Attached to S0 were:
  • 4 x MTS (Module to Truss Structure) struts. These were used to connect it to the Destiny module
  • Airlock Spur. This was a 4.2 m beam that hinged out to connect to the Quest module and had handrails for spacewalkers
  • Mobile Transporter (MT). This was made by TRW Astro Aerospace in Carpinteria and was an 885 kg, 2.7 m long truck which moved on the S0 rails to transfer heavy cargo along the truss.
• Sill: RMS arm - 410 kg
• Total: 15193 kg

The Quest airlock was depressurized at 1236 GMT. Cosmonaut Budarin supported the operations from inside the station. One of the more important tasks was to reroute power cables for two of the station's critical control moment gyros, so that the pair could not be disabled by any single power disruption. This was important to provide extra redundancy, since one of the four total gyros has already failed and could not be replaced due to the grounding of the shuttle fleet after the STS-107 disaster.

Delayed from November 4, 2002, and January 21, February 2 and 4, March 5, 8 and 21, and April 6, 2003. As of 2007 Feb 4 located at 89.84W drifting at 0.014W degrees per day.

White Knight/SpaceShipOne Flight 53L / 13P. 40 second motor burn time. Handling qualities during boost, through transonic and supersonic. Reaction control system functionality in-flight and feather configuration stability during transonic re-entry. Evaluation of radar tracking capability. Launch conditions were 13.96 km and 230 kph. A planned immediate motor ignition was delayed about 2 minutes to evaluate a shock induced stall buffet resulting in an ignition altitude of only 11.7 km. The 40 second rocket boost was smooth with good control. Pilot commented that the motor was surprisingly quiet; however the boost was heard by ground observers. Burnout occurred at 1.6M and apogee was over 32 km. There was no noted flight control flutter or buzz during the climb. Feather recovery was nominal. Maximum feathered speed on entry was 0.9 Mach. The wing was de-feathered and locked by 12 km. Handling quality assessments during descent were satisfactory and a smooth landing made to runway 30 at Mojave. All video and tracking systems performed well with spectacular footage obtained onboard, from chase and from ground stations.

Launched the EO-17 long-duration crew to replace the EO-16 crew. The commander was the son of cosmonaut Aleksandr Volkov. Also aboard was Oleg Kononenko (no relation to the 1970's Buran pilot of the same name) and Korean astronaut Yi Soyeon. Soyuz TMA-12 docked at the Pirs module of the International Space Station on 2008 Apr 10 at 12:57 GMT on 10 April. Volkov and Kononenko stayed aboard as the EO-17 long duration crew. Yi returned to earth with the EO-16 crew aboard Soyuz TMA-11.
