1971 in spaceflight
	Salyut 1, the first space station and Soyuz 11, the first mission to successfully dock with it, were launched in 1971. The crew were killed during reentry when their spacecraft depressurised

1971 saw the last three known deaths of cosmonauts of the Soviet space program and the only deaths in space. Their mission was to man humanity's first space station. The experimental bay door failed to separate so the first crew failed to dock and second crew were killed on re-entry. 1971 also saw the launch of the first and only British satellite on top of a British rocket after that success the program was cancelled.

EVAs

Start Date/Time	Duration	End Time	Spacecraft	Crew	Remarks
5 February 14:42	4 hours 48 minutes^[22]	19:30	Apollo 14 Apollo LM-8 "Antares"	Alan Shepard Edgar Mitchell	Shepard and Mitchell deployed several experiments on the lunar surface near the landing site, such as the Solar Wind Composition Experiment and the Apollo Lunar Surface Experiments Package (ALSEP). The crew also took a contingency sample and planted a U.S. flag at the site.^[23]
6 February 8:11	4 hours 34 minutes	12:45	Apollo 14 Apollo LM-8 "Antares"	Alan Shepard Edgar Mitchell	Planned as a traverse to Cone Crater, however the astronauts were unable to find the rim of the crater amid rolling terrain. The crew also took panoramic pictures and set up additional experiments. Shepard famously hit a golf ball on the lunar surface, using a six iron golf club head attached to the handle of an excavation tool.
31 July 00:16	33 minutes	00:49	Apollo 15 Apollo LM-10 "Falcon"	David Scott	Scott stood on the lander’s ascent engine cover to survey the landing site through the vehicle’s docking hatch and take panoramic photography.
31 July 13:13	6 hours 32 minutes^[24]	19:45	Apollo 15 Apollo LM-10 "Falcon"	David Scott James Irwin	Scott and Irwin visited Elbow Crater near the rim of Hadley Rille using the Lunar Roving Vehicle (LRV), marking the first time humans traveled in a wheeled vehicle on another world. The crew also deployed an ALSEP on their return to the landing site.^[25]
1 August 11:48	7 hours 12 minutes	19:01	Apollo 15 Apollo LM-10 "Falcon"	David Scott James Irwin	Scott and Irwin drove the LRV 12.5 miles along the base of the Apennine Mountains, visiting several craters, collecting samples and taking panoramic photography. The crew also took a deep core sample of lunar soil and planted a U.S. flag.
2 August 08:52	4 hours 49 minutes	13:42	Apollo 15 Apollo LM-10 "Falcon"	David Scott James Irwin	Scott and Irwin traveled to Scarp Crater then northwest along the rille, collecting samples. The crew also retrieved the core sample drilled during the previous EVA.
5 August 15:31	39 minutes	16:10	Apollo 15 Apollo CSM-112 "Endeavour"	Alfred Worden James Irwin	First spacewalk in deep space, conducted during the return trip to Earth. Worden retrieved exposed film from the Scientific Instrument Module (SIM) bay of the Service Module, while Irwin stood in the hatch.
