The two-man crew selected to become the second group of occupants for the Soviet Union’s Salyut 4 space station nearly rockets into disaster. Interstage connectors, intended to open simultaneously to allow the third stage of the booster to carry the Soyuz spacecraft into orbit, fail to open on cue, leaving the third stage dragging the dead weight of the spent second stage, changing the trajectory of the entire vehicle. The Soyuz capsule carrying cosmonauts Vasili Lazarev and Oleg Makarov is blasted free, and the two men experience acceleration of 23 Gs as the capsule roars toward a bruisingly rough emergency landing. As if that’s not bad enough, the Soyuz capsule lands perilously close to the USSR’s border with China, and rescue crews spend over 24 hours looking for the crew. The usually secretive Soviet space agency reluctantly reveals details of the mission to NASA, with whom they are collaborating ahead of the historic Apollo-Soyuz joint launch.

The TV movie-of-the-week The Invisible Man airs on NBC, starring David McCallum (The Man From UNCLE, Colditz), Melinda Fee, and Jackie Cooper. This is the first TV series to credit Harve Bennett (of The Six Million Dollar Man and Star Trek II) as one of its creators, alongside Steven Bochco, for whom The Invisible Man is his second such credit. The movie achieves a high enough rating to merit a series pickup later in 1975.
NASA launches Explorer 53, renamed Small Astronomy Satellite C, from an Italian-owned offshore launch platform off the coast of Kenya. SAS-C is a smaller spacecraft than NASA’s larger Orbiting Astronomical Observatory (OAO) series, but can be aimed very precisely at any cosmic X-ray sources that it detects. One of SAS-C’s discoveries is MXB1730-33, a binary star giving off rapid X-ray bursts. SAS-C will remain in orbit and functional until it re-enters Earth’s atmosphere in 1979.

Soyuz 18 is launched toward space station Salyut 4 by the Soviet Union. Cosmonauts Pyotr Klimuk and Vitali Sevastyanov set a new Soviet record for long-duration stays in space, remaining about Salyut 4 for two months. They are also aboard Salyut 4 during the entirety of the Apollo-Soyuz Test Project, and are able to contact that international mission’s Soviet crew in another Soyuz vehicle. (Two mission control centers are used to prevent any confusion between the two Soyuz crews.) At the time the Soyuz 18 crew abandons Salyut 4 in July, the station’s environmental systems are failing, allowing the atmosphere inside the station to become humid enough for mold to begin growing on surfaces in the crew compartment; no further human crews will visit the station.

NASA launches the Nimbus 6 satellite, designed to observe weather patterns from orbit and test new weather and climate detection technologies. In addition to continuing the microwave and infrared observations carried out by Nimbus 5, Nimbus 6 studies the amount of solar radiation reaching or reflected by Earth, and sends real-time observations to the experimental ATS-6 satellite, allowing NASA to test techniques and technologies that will be used in the shuttle-era TDRS (Tracking & Data Relay Satellite) system.
