Prime Minister Winston Churchill of England was informed of reports on German experiments with long-range rockets.

Peenemuende team moved from White Sands to Huntsville

The first Redstone missile battalion, the 217th Field Artillery Missile Battalion, was formally activated at Redstone Arsenal.

In response to a request by the DOD-NASA) Saturn Ad Hoc Committee, the Army Ordnance Missile Command (AOMC) sent a supplement to the "Saturn System Study" to the Advanced Research Projects Agency ARPA describing the use of Titan for Saturn upper stages. - Additional details.

Successful missile test. Missed aimpoint by 17 m.

Reached an altitude of 200,000 km before plunging back to earth.

KH-1; film capsule recovery failed. Mission failed. Attitude control system malfunctioned.

According to the work schedule, GT-2 could fly on August 24 and GT-3 on November 16, with comfortable allowances for four-week slips for each mission. Some special attention was devoted to GT-2, where the spacecraft had become the pacing item, a position held by the launch vehicle on GT-1. Spacecraft No. 2 systems tests had started one month late but were proceeding well. In addition, the schedule looked tight for starting spacecraft No. 3 systems tests on June 1.

The first firing of the LEM ascent engine test rig (HA-3) was successfully conducted at White Sands Missile Range, New Mexico. A second firing on April 23 lasted 14.45 sec instead of 10 sec as planned. A third firing, lasting 30 sec, completed the test series. A helium pressurization system would be installed before additional testing could begin.

Tank fabrication had begun September 25, 1964. Aerojet-General delivered the stage I engine on June 16 and the stage II on August 20. In the meantime, tank splicing was completed August 3. Engine installation was completed September 23, and all hoizontal testing ended September 27.

Central Committee of the Communist Party and Council of Soviet Ministers Decree 'On Co-operation of the USSR and Socialist Countries in the Sphere of Research and Use of Space-international co-operation' was issued.

Associate Administrator for Manned Space Fight George E. Mueller informed Deputy Administrator Robert C. Seamans, Jr., of the Saturn/Apollo Applications Program Office's evaluation of a Lockheed proposal to launch space probes from orbit using Agena rockets launched from AAP stations in space. The proposal was feasible, Mueller advised, but did not seem a desirable mission for inclusion in the AAP. - Additional details.

MSC Director Robert R. Gilruth summarized Houston's position expressed during discussions with Associate Administrator for Manned Space Flight George E. Mueller two days earlier. Gilruth cited NASA s need for a manned space flight goal other than 'using Apollo hardware' (and suggested a Mars flyby or landing mission as an in-house focus for planning.) Also, he repeated his concern over the imbalance between AAP goals and resources, as well as the extent of engineering redesign and hardware modification that had been forced upon the project. Though expressing his and MSC's desire to contribute to and be a part of AAP, Gilruth voiced concern that 'the future of manned space flight . . . is in jeopardy because we do not have firm goals, and because the present approach appears to us to be technically unsound.'

Cosmos 213 was the target for Cosmos 212 in a successful test of Soyuz 7K-OK rendezvous and docking systems. The Cosmos 213 launch was the most accurate yet. The spacecraft was placed in orbit only 4 km from Cosmos 212, ready for a first-orbit docking. Both spacecraft were recovered, but Cosmos 213 was dragged by heavy wind across the steppes when the parachute lines didn't jettison at touchdown. This failure caused the upcoming Soyuz 2/3 manned docking mission to be scaled back.
Officially: Investigation of outer space, development of new systems and elements to be used in the construction of space devices. - Additional details.

High resolution photo reconnaissance satellite; returned film capsule

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

At 00:21:35 GMT Apollo 13 passed behind the moon, out of radio contact with earth. Flying high above the lunar surface, the crew reached a distance of 401,056 km from the center of the earth, an all-time altitude record. At 02:40:39 GMT the cold, exhausted, and ailing crew conducted a completely manual 4 minute 23 second burn of the LM descent engine to reduce the coast time back to earth and moved the landing point from the Indian Ocean to the South Pacific. - Additional details.

Anokhin injured in the crash of a Tu-16 into the Aral Sea. The bomber was flying parabolas for zero-G tests of the engine of the Block L stage of Mishin's bureau, to study why the stage was continually failing to restart in earth orbit.

The Salyut station was prepared in a huge two story bunker built for launch vehicle / payload processing. The contrast between the money lavished by the military on this facility for Chelomei's projects and the limited funds available for a proper N1 preparation and test facilities was enormous. Here funds were available without limit. The air was controlled by a self-contained environmental control system with its own independent electrical-diesel generators. The facility was a miracle. It was shocking that this was made available for Almaz, while the military told Mishin that he would have to prepare the immense MKBS station in the uncontrolled environment, subject to frequent power blackouts, of the N1 facility. At Chelomei's facility, everything was completely checked out on earth prior to launch.

The Proton booster is erected on the pad. The decision is made to proceed despite a prediction of 15 m/s winds -- the prediction turns out to be wrong. All of the big brass are present for the rollout. Afterwards Mishin visits the cosmonauts. He says all is ready for the first space station mission, and promises them the N1-L3 will be available soon for lunar missions.

Photo surveillance; returned film capsule.

Area survey photo reconnaissance; returned film in two small SpK capsules during the mission and with the main capsule at completion of the mission.

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

The Ikar upper stage entered a 234 km x 900 km transfer orbit, then maneuvered to dispense the four spacecraft into 900 km x 950 km x 52.0 deg parking orbits. The satellite's own thrusters would be used to place them into their 1410 km circular operational orbits. The Ikar stage deorbited itself after one day. The Globalstar satellites, built by Alenia and Loral, are L-band comsats which provide satellite phone service.

The vehicle entered a 175 km x 706 km x 98.2 deg initial orbit. 57 minutes after launch the Delta stage burned again to circularize the orbit at 668 km x 698 km and Landsat 7 separated from the stage. The Delta stage then burned to depletion of its propellant, into a 184 km x 710 km x 107.5 deg orbit that would decay quickly. The Landsat 7 remote sensing satellite was to be operated by NASA/Goddard until October 2000, when operations would be transferred to the US Geological Survey.

Flight Time: 0.7 hours Pilot: Melvill Copilot: Binnie. Objectives: Repeat airshow maneuver practice Results: Minor tweaks to refine the airshow demonstration maneuvers.

The Soyuz TMA-6 docked with International Space Station's Pirs module at 02:20 GMT on April 17. Commander of the long-duration EO-11 crew was Russian cosmonaut Sergey Krikalyov. Flight engineer and science officer was American astronaut John Phillips. Italian Roberto Vittori accompanied the EO-10 crew aboard Soyuz TMA-6 to the station on the European Space Agency EP-8 Eneide mission.

Delayed from April 15; October 18, 19, 26, 28; Nov. 4, 9 and 11; 2004, and March 2, 2005. Autonomous Rendezvous Technology mission, planned to guide itself to within a few metres of a US satellite. On April 16, DART closed within 100 m of the MUBLCOM satellite, then evidently began a series of out-of-control maneuvers resulting in an in-space collission and MUBLCOM being bumped into a 3 to 5 km higher orbit. Remarkably both satellites continued to function. DART then detected that it was running unexpectedly low on nitrogen cold gas used for orientation. Its autonomous software aborted further rendezvous operations and the DART was deorbited shortly thereafter.

FORMOSAT-3 consisted of six small 62 kg Orbcomm-type satellites with GPS receivers which were to measure atmospheric conditions by studying the effect of the atmosphere on GPS satellite signals passing through it. The satellites, also known as COSMIC (Constellation Observing System for Meteorology, Ionosphere and Climate), would eventually be positioned in equally spaced orbit planes at around 800 km altitude.
