The first Air Force Thor IRBM flight test missile (Number 115) to be fired from a tactical-type launcher was launched at Cape Canaveral. The missile completed a successful flight, impacting 1,170 nautical miles downrange. This was also the first Thor to be launched without a flight readiness firing of its propulsion system. USAF Thor flight tested for the first time from a tactical-type launcher at Cape Canaveral.

Initial attempt to launch a live nuclear weapon using the Thor IRBM from Johnston Atoll. The range safety radar had been unreliable before launch,. Five minutes after launch, after shutdown of the booster, the Johnston missile tracking system failed. Unable to monitor the warhead's flight path, the range safety officer destroyed it 10 minutes later, prior to warhead detonation.

All is ready, but the wind is predicted to by 15 to 20 m/s on 7 June. The launch vehicle cannot be launched in winds over 15 m/s. Bykovskiy and Tereshkova are confirmed as the crew for 8 and 3 day flight durations. When they return to earth, a new and difficult life as celebrities will begin for them -- they will be known all over the world.

Korolev presents the Voskhod technical design to organisations outside of OKB-1. Over 27 VVS representatives, including 10 cosmonauts, attend. The two Vostok variants have been dubbed 3KV (3-crew version) and 3KD (2 crew version with airlock). Korolev will complete integration of the first 3KV article by 12 June (8 days from the briefing). The first two articles will be shipped to Baikonur on 15 June for final test. An unmanned test flight with mannequins will be made in July, with the first three-crew manned flight in August. This will be followed by the first 3KD flight in September, with the first spacewalk. The difficulty in preparing equipment and training crews on this schedule are immense; and the chances of complete success are low. But it is the only way the Soviet Union can maintain its leadership in space in the face of the impending Gemini and Apollo flight tests, and the delays in Soyuz. After the meeting, Kamanin decides to train two cosmonauts as Voskhod spacecraft commanders, and the other three as spacewalkers.

NASA released a new AAP launch readiness and delivery schedule. The schedule decreased the number of Saturn flights to 11 Saturn IB flights and one Saturn V flight. It called for three Workshops. One of the Workshops would be launched by a Saturn IB, and another would serve as a backup. The third Workshop would be launched by a Saturn V. The schedule also included one ATM. Launch of the first Workshop would be in November 1970. Lunar missions were no longer planned in the AAP.

There are a total of 500 staff at Yevpatoriya for the mission, including 53 representatives from the VVS, 6 military cosmonauts, and 3 civilian cosmonauts. Mishin returns to Moscow, leaving Tregub in his place. In the afternoon there is a problem with the control of the spacecraft's solar cells. On the 47th orbit Sevastyanov reports that one solar panel is energised, but only generating 26 amps. This could only mean that the automatic control of the solar panels was not working. On the second day the crew had to engage and disengage the solar batteries 12 times manually. After the 15th manual session it became clear that the mission could last only eight days before the batteries would run down. In the orbit of Soyuz 9 in June, the night lasts 40 minutes. On the previous flight, in October, it lasted only 10 minutes and this would not have been a problem. The crew is told to revolve the spacecraft at 0.5 deg/sec around the long axis. By this method the spacecraft remains fully oriented towards the sun, and the batteries don't have to work so long on the night passes. The cosmonauts do not report any unpleasant sensations from the rotation. At the 23:25 communications sessions the cosmonauts report that their appetites are good and they are sleeping well.

Central Committee of the Communist Party and Council of Soviet Ministers Decree 'On standardised weather satellite system' was issued. The resolution also ordered VNIIEM to develop a parallel design of another meteosat for the hydrology office alone. This was not put into production.

Soyuz 11 is on the launch pad, and which crew will fly is still being argued. Kamanin wants to simply have Volkov replace Kubasov on Leonov's crew. Mishin wants the complete backup crew to replace Leonov's crew. Others on the launch commission support Mishin. At 15:30 a team of physicians arrive from Moscow to verify the diagnosis of Kubasov. At 18:00 the final state commission meeting confirms the Dobrovolsky crew. At 19:00 a press conference is held - Dobrovolsky, Patsayev, and Volkov are publicly presented as the crew of Soyuz 11.

The Cluster satellites were a series of sophisticated earth-observation platforms that were to be launched aboard the first Ariane 5. The explosion of the booster led to a costly setback for European space science. There were no back-up spacecraft. Some instruments may fly on other future satellites.

Discovery's crew was awakened this afternoon to begin readying its spaceship for the return trip home early Sunday morning. But before that, the crew has one last mission objective to complete: The deploy of a small educational satellite at 2:21 a.m. Saturday. Additional Details: here....
