A rocket-boosted glider is flown by Friedrich Stamer from the Rhoen Mountains in Western Germany. The development was funded by Opel, the canard-layout glider designed by Hans Lippisch, and the powder rockets developed by Sander. As in the Opel ground vehicles, a boost rocket (360 kgf for 3 seconds) was to accelerate the glider down the launch ramp. A sustainer rocket (20 kgf for 30 seconds) would keep the aircraft in flight. It was hoped to develop a method of launching gliders that would allow the pilot to get airborne without assistance - that did not require a tow aircraft or the eight-man crew needed to pull back the rubber band on existing rail launchers. Tests with smaller motors in models showed the high-thrust motors were too powerful, so the full-scale tests used a standard rubber-band rail launcher with only the low thrust motors installed. After two attempted flights, Stamer finally made a successful flight, firing two 20 kgf motors one after the other. The glider flew about 1.5 km in 70 seconds. On the second flight the first motor exploded, setting the aircraft on fire. Stamer landed successfully but further attempts were abandoned.

Launched 03:22 local time. Reached 62.4 km. Carried pressure, temperature, composition, ionosphere, sky brightness, solar radiation experiments for Air Research and Development Command. Also carried Albert, the first American primate in space, who died of suffocation.

The first Atlas Series A flight test missile (4A) had to be destroyed shortly after launch from Cape Canaveral due to a booster engine shutdown and loss of thrust. From a technical standpoint, however, this first booster-only launch successfully demonstrated the launching mechanism, structural integrity of the airframe, subsystems performance, and operating procedures for launch crew personnel. First test flight of prototype WS-107A Atlas was detonated by command signal at 10,000 feet following a failure in the booster fuel system. The 23-second flight was considered a partial success.

The projection is made that the US will surpass the USSR in space in 1963-1964. Kennedy's 1961 speech announcing the Apollo project to land on the moon was passed to Vershinin for comment, but no reply was ever received. Rudenko, Vershinin, and especially Malinovskiy see no role for piloted space flight, let alone flights to the moon. America, with its superior electronics capability, is still proceeding with development of manned spacecraft that require the active piloting of the astronaut. Why then, Kamanin fumes, is the USSR trying to develop completely automated manned spacecraft? Military space is being run in the USSR by men who know nothing of it, he notes. Rudenko is ill, and not even at the conference.

The Department of Defense announced the reassignment of responsibility for the Defense Department Communication Satellite program (Advent). The Air Force was now given responsibility for the development, production, and launch of all space devices, in line with the policy on military space systems originally delineated on 6 March 1961. The Army retained responsibility for the ground system. The Defense Communications Agency (DCA) assumed overall responsibility for integration.

The cosmonauts spend the day on the beach. Tereshkova sits a long time with Korolev on the balcony on the second floor of the house on the river. He interviews here thoroughly to make sure she is ready for the flight. The State Commission meets at 17:00. The expected solar flare did not occur, but the Crimean Observatory claims the risk will remain high. The decision is made to defer the launches to 14/15 June.

MSC ordered Grumman to propose a gaseous oxygen storage configuration for the LEM's environmental control system (ECS), including all oxygen requirements and system weights. Because no decision was yet made on simultaneous surface excursions by the crew, Grumman should design the LEM's ECS for either one-or two-man operations. And the Center further defined requirements for cabin repressurizations and replenishment of the portable life support systems. Oxygen quantities and pressures would be worked out on the basis of these ground rules.

Dale D. Myers, Apollo CSM Program Manager at North American Rockwell, advised MSC officials of his company's investigation of two pilot-chute riser failures during recent drop tests of the Block II earth-landing system. Should there be any imperfections in either hardware or assembly techniques, Myers explained, the Block II pilot chute and riser system could be a marginal-strength item. Investigations had determined that early manufacturing processes had allowed a differential length between the two plies of nylon webbing in the pilot-chute riser which caused unequal load distribution between the two plies and low total riser strength. Because of the earlier test failures, Myers said, the pilot chute riser had been redesigned. The two-ply nylon webbing had been replaced by continuous suspension lines (i.e., 12 nylon cords) and the 5.5-millimeter-diameter cable was changed to 6.3-millimeter cable. He then cited a series of recent tests that verified the redesigned pilot-chute riser's strength to meet deployment under worst-case operational conditions.

Things are proceeding normally aboard Soyuz 9. Shatalov and Yeliseyev prepare to depart for the Crimea to train for use of the big solar and stellar telescopes planned for the DOS station. The 15-20 day course will be attended by all 12 DOS cosmonauts. The training plan for DOS is discussed, with a May 1971 flight date as the objective. Kamanin discusses smoking with Bykovsky and Gorbatko - they have to stop.

Decree 'On selection of design layout for Buran' was issued. Following exhaustive analysis and inability to improve on the design, a straight aerodynamic copy of the US space shuttle, was selected as the Buran orbiter configuration. MiG was selected as subcontractor to build the orbiter. For this purpose MiG spun off a new design bureau, Molniya, with G E Lozino-Lozinskiy as chief designer.

The MBS had been unberthed sometime around 2220 UTC and docked to the Mobile Transporter at 1304 UTC on June 10. On June 11 at about 1515 UTC the Quest was depressurized again, with Chang-Diaz and Perrin opening the hatch around the same time and going to battery power at 1520 UTC. During this spacewalk the astronauts completed setting up the MBS system. The hatch was closed at 2016 UTC and Quest was repressurized at 2020 UTC.

Satellite jointly owned by Singtel Optus Pty and the Australian Dept. of Defense. Previous satellites in the series were purely civilian and didn't carry the dedicated defence communications equipment. Prime contractor for the satellie was Mitsubishi, using a Loral FS-1300 bus with UHF, X-band and Ka-band communications transponders. As of 2007 Mar 11 located at 109.87E drifting at 0.009W degrees per day.

Docked with the Tiangong-1 spacelab on June 13 at 05:11 GMT. On June 23 the crew carried out a redocking exercise. They undocked Shenzhou 10 from Tiangong at 00:26 GMT, backed away from the station, and redocked with it at 02:00 GMT. On June 24 the crew undocked for the final time, made a flyaround of the Tiangong station, and then prepared to return to Earth. The deorbit burn was at about 23:23 GMT Jun3 25. The capsule landed in China at 00:07 GMT June 26, at 42.33N 111.36E.

The NROL-37 mission was a large signals intelligence (SIGINT) satellite, placed in geosynchronous orbit at 103 deg E over the Indian Ocean. Possibly the second Orion/Sharp model. There were two main lineages of GEO SIGINT satellites operated by the US National Reconnaissance Office: MERCURY (originally CANYON); and RHYOLITE (later AQUACADE), which was replaced in the 1980s by ORION (whose other rumoured codenames include MAGNUM and MENTOR). Launches of the MERCURY series ended in 1998, at which time it was rumoured that its capabilites would be merged into the ORION series. A number of observers suggested that the 2014 GEO SIGINT launch of USA 250 on an Atlas V was a one-off mission not part of the ORION series, and that with an increase in mass ORION had moved to using the RS-68A-powered Delta 4 Heavy rockets. It was further been suggested that the 2014 launch might be the NEMESIS 2 satellite mentioned in leaked FY2013 budget documents; however a close reading of those documents showed that funding for the latter project was cut off after FY2011, which implies that it was either launched by then or cancelled (more likely given the sudden drop from half-billion-dollar-level funding to zero). The documents also mention SHARP, the SIGINT High Altitude Replenishment Program, funded at a high level in FY2011-2013 and reportedly also since. It's possible the 2012 and 2016 launches may represent a new ORION/SHARP series, or that they are beefed up ORION and the 2014 launch was a SHARP prototype. The shorter fairing used for the 2014 launch suggests that it was not in fact an ORION.
