Ionosphere research. Launched at 1210 local time. Reached 135.2 km.

USAF X-17 flight test program started at Cape Canaveral to study reentry problems by simulating reentry velocities and conditions with three-stage solid-fuel Lockheed X-17. A total of 26 X-17 flights were conducted until March 1957.

Ionosphere research. Launched at 1120 local time. Reached 111.1 km.

The missile launched from the repaired LC-9 on the third attempt. At T+42 seconds, Mach 1.63, and 7,000 m altitude, a fire occurred in the engine compartment after a failure of a regenerative cooling valve to the gas generator. The turbopump shut down, and one engine went out. Nevertheless the vehicle continued, first on one engine, then coasting, to 12,000 m altitude, and the booster separated successfully. But the cruise stage was below ramjet ignition velocity. Again ground control could bring the cruise stage under control as a glider, flying it to an impact 87 km downrange

Launched at 0609 hours EST from AMR to test performance of the inertial guidance system, angle-of-attack meters, separation of explosive screws, and impact and radar fusing systems. Range instrumentation difficulties and deteriorating weather delayed the firing from the initially scheduled time of 0230 hours EST. The flight was successful. Actual range was 135.425 nm; 0.42 nm over; and 389 meters left of the intended impact point. Missed aimpoint by 785 m.

Meetings were held with NACA, AVCO, and Lockheed representatives in attendance to consider materials for thermal protection of satellite reentry vehicles.

A Navy YFNB barge was obtained by NASA to serve as a replacement for the Palaemon in transporting of the Saturn booster to Cape Canaveral.

First launch of an Atlas from Vandenberg AFB as a target for an Army Nike-Zeus from Kwajalein.

First launch of an Army Nike-Zeus from Kwajalein against an Atlas from Vandenberg AFB.

The first full-scale firing of the SM engine was conducted at the Arnold Engineering Development Center. At the start of the shutdown sequence, the engine thrust chamber valve remained open because of an electrical wiring error in the test facility. Consequently the engine ran at a reduced chamber pressure while the propellant in the fuel line was exhausted. During this shutdown transient, the engine's nozzle extension collapsed as a result of excessive pressure differential across the nozzle skin.

MSC announced that it had contracted with the Martin Company to develop a frictionless platform to simulate the reactions of an extravehicular astronaut in five degrees of freedom-pitch, yaw, roll, forward-backward, and side-to-side. MSC Crew Systems Division would use the simulator to test and evaluate space suits, stabilization devices, tethering lines, and tools.

Lozino-Lozinsky was selected as project manager. The Spiral system consisted of three main components: the GSR reusable hypersonic air-breathing launch aircraft; RB expendable two stage rocket; and the OS orbital spaceplane.

State commission sets November as date for manned circumlunar flight. The next L1 flight was set for July, with flights to continue at monthly intervals at each translunar launch window. 3 or 4 unmanned flights had to be successful before a manned flight would be attempted.

The State Commission determines the cause of the Proton booster shutdown in April was a short in the L1 abort system. This sent an incorrect abort signal to the launch vehicle, triggering it to shut down its engines. The next L1 launch is set for 19 July, followed by one launch per month thereafter. After 3 or 4 successful unmanned circumlunar missions, the spacecraft will be cleared for a manned lunar flyby.

High resolution photo reconnaissance satellite; returned film capsule

The Soyuz 9 crew are still suffering from the effects of their flight, but getting better each day. Tereshkova was taken ill last night.

Operation of a system of long range telephone-telegraph radiocommunication, and transmission of USSR Central Television programmes to the stations of the Orbita network.

Area survey photo reconnaissance satellite; returned film capsule.

The crew has completed all scientific and technical experiments aboard the Salyut station. They will spend the last two to three days concentrating on physical training, medical observations, and preparation for landing. They will turn off all station equipment not required for autonomous flight, prepare the Soyuz for landing, and measure the water and consumable reserves available for the next crew. The experiments have produced many film cartridges, experiment samples, and so on that should be returned to earth. However there is not enough space or mass reserves in the Soyuz capsule for them all so they are only to return those specifically listed by ground control.

Superbooster failure of N1 serial number 6L. This was a substantially improved vehicle, incorporating filters in the propellant lines to prevent any foreign objects from getting into the pumps. The shape of the tail of the booster was modified, and ventilation and refrigeration systems were added to keep the engine compartment cool. It was painted white overall to reduce temperatures while sitting on the pad. After liftoff and ascent, an axial rotation was introduced by gas dynamics interactions of the thirty engines with the air slipstream. The launch vehicle developed a roll beyond the capability of the control system to compensate. and began to break up as it went through Max Q. Control was lost at 50.2 seconds into the flight and it was destroyed by range safety a second later. The engines functioned well and did not shut down up to the point of vehicle destruction. No functional payload was carried. It has been stated that this launch did not have a working launch escape system. - Additional details.

NASA Deputy Administrator George M. Low and Associate Administrator for Manned Space Flight Dale D. Myers met and decided there was no foreseeable mission for CSMs 115 and 115a; funds would not be authorized for any work on these spacecraft; and skills would not be retained specifically to work on them.
