A greatly expanded NACA program of space flight research was proposed in a paper, "A Program for Expansion of NACA Research in Space Flight Technology," written principally by senior engineers of the Lewis Aeronautical Laboratory under the leadership of Abe Silverstein. The goal of the program would be "to provide basic research in support of the development of manned satellites and the travel of man to the moon and nearby planets." The cost of the program was estimated at $241 million per year above the current NACA budget. References: 16 .
By the end of the year, over 70 different models had been tested by facilities at the Air Force's Arnold Engineering Development Center and the NASA Langley, Ames, and Lewis Research Centers. References: 483 .
A voice message was sent from Washington, D.C., to Woomera, Australia, by way of the moon. NASA Deputy Administrator Hugh L. Dryden spoke by telephone to Goldstone, Calif., which "bounced" it to the deep-space instrumentation station at Woomera. The operation was conducted as part of the official opening ceremony of the Australian facility. References: 16 .
At the first meeting of the House Committee on Science and Astronautics, during the first session of the 87th Congress, Charles F. Ducander, Executive Director and Chief Counsel of the Committee staff, outlined a number of proposed subjects for study. One subject was the Air Force's interest in a three-man spacecraft similar to the Apollo spacecraft planned by NASA. A Committee staff member had been assigned to investigate this duplication of effort. On February 22, testifying before the Committee, Air Force Undersecretary Joseph V. Charyk stated that the Dyna-Soar program was a direct approach to manned military space applications. The Air Force interest in an Apollo-type spacecraft was part of the post-Dyna-Soar program, Charyk said. References: 16 .

MSC directed Grumman to stop all work on the LEM Little Joe II program. This action followed the ASPO Manager's decision against a testing program for the LEM comparable to that for the CSM. References: 16 .
Interdepartmental Scientific-Technical Council on Space Research (MNTS-KI) Decree 'On approval of the L3 draft project' was issued. The decree followed a review by a Keldysh-led Academy of Sciences state commission the previous December. The decree moved the first flight of the N1 to the end of 1966. References: 474 .

The Board of Inquiry into the January 20 S-IVB-503 explosion at the Douglas Sacramento Test Facility identified the probable cause as the failure of a pressure vessel made with titanium-alloy parent-metal fusion welded with commercially pure titanium. The combination, which was in violation of specifications, formed a titanium hydride intermetallic that induced embrittling in the weld nugget, thus significantly degrading the capabilities of a weldment to withstand sustained pressure loads. The Board recommended pressure limitations for titanium-alloy pressure vessels. References: 16 .

Unmanned resupply vessel to Mir. Conducted third test of Buran ejection seat during ascent to orbit. The K-36M.11F35 seat was installed in an 'experimental droppable compartment' installed in place of the Launch Escape Tower engine on top of the shroud. Docked with Mir on 12 Feb 1989 10:29:38 GMT. Undocked on 3 Mar 1989 01:45:52 GMT. Unfurled experimental space mirror petal structure on undocking. Destroyed in reentry on 5 Mar 1989 01:59:00 GMT. Total free-flight time 4.08 days. Total docked time 18.64 days. References: 1 , 2 , 6 , 275 .

Mir Expedition EO-23. Soyuz TM-25 docked with Mir at the forward port on February 12 at 15:51:13 GMT.
Following a mission that seemed to consist of an endless series of collisions, breakdowns, fires, and other emergencies, the EO-23 handed over the station and on August 14 entered Soyuz TM-25 landed in Kazakstan at 12:17 UTC, 170 km SE of Dzezkazgan. The Soyuz landing rockets failed to fire on touchdown, giving one of the roughest landings experienced by a returning Mir crew. Additional Details: Soyuz TM-25. References: 4 , 9 , 51 , 276 .
X-ray astronomy satellite. Stage 1 lost control, and separated with the rocket off-course at 75 seconds in the flight. Stage 2 burned correctly and separated at 218 seconds, followed by the third stage burn at 621 seconds. Last signals were received at 20 minutes after launch. ASTRO-E was to have separated from the third stage at 23 minutes, but ended in an orbit with a perigee of only 80 km and an apogee of 410 km. It probably reentered on the first orbit at around 0230 - 0300 GMT somewhere between East Africa and western China.
