Eleven companies submitted contract proposals for the Saturn second stage (S-IV): Bell Aircraft Corporation; The Boeing Airplane Company; Chrysler Corporation; General Dynamics Corporation, Convair Astronautics Division; Douglas Aircraft Company, Inc.; Grumman Aircraft Engineering Corporation; Lockheed Aircraft Corporation; The Martin Company; McDonnell Aircraft Corporation; North American Aviation, Inc.; and United Aircraft Corporation.

Advanced Research Projects Agency (ARPA) issued an interim directive cancelling the three-phase development program for a military communication satellite system. Pending a Joint Chiefs of Staff (JCS) and OSD review, Projects Steer, Tackle, and Decree were replaced by a single synchronous communications satellite system subsequently designated Project Advent. AFBMD was directed to conduct a single integrated research and development program for a 24-hour synchronous equatorial global communication satellite system. The Army was to develop the communications equipment while AFBMD handled the booster and spacecraft.

The second multiple launch of two SAC Minuteman I missiles was conducted at Vandenberg AFB. Minuteman I (LGM-30A) missiles (FTM 581 and 636) were successfully launched from Vandenberg 20 minutes apart in the first ripple mode launch ever conducted. In this mode, a single launch crew gave both commands to launch.

For this L1 launch Chelomei wants to film separation of the first and second stages of the Proton rocket at 126 seconds into the flight - altitude 41 km, distance downrange 47 km. To do this two An-12 and one Tu-124 with long focal-length cameras will orbit 35 to 40 km from base. The discussion turns to how to recover the L1 if it lands in the ice-bound Aral Sea. The circle of possible landing points has a radius of 500 km from a point west of Karaganda. For political reasons it is not possible to deploy recovery forces to areas of Iran and India that are within this circle.

Ionospheric sounding. Japanese Ionospheric Sounding Satellite (JISS - national name 'Ume') is intended for regular observations by means of radio waves of the global distribution of the critical frequencies of the ionosphere, and for utilization of the results of the observati on for radio wave forecasts and warning necessary for effective operation of short-wave radio-communication. Time of launch 0330UT.
