Voskhod 2 carrying Voskhod 3KD spacecraft carried two cosmonauts, Pavel Belyayev & Alexey Leonov, to orbit. The craft was equipped with an inflatable airlock in order to conduct the first ever spacewalk. Alexey Leonov became the first person to do so by performing a 12 minute spacewalk. The mission lasted 1 day, 2 hours, 2 minutes & 17 seconds completing a total of 17 orbits around Earth. The mission had many issues, for example during his spacewalk his spacesuit ballooned up to a point where his suit became stiff. In order to move his limbs again and re-enter the airlock he had to bleed off some of the suit's pressure. After re-entering the capsule,the crew had trouble sealing the hatch, during re-entry the orbital module did not properly disconnect from the landing module causing the spacecraft to spin wildly until turbulence caused them to separate at around 100 km and the automatic landing system failed and the crew had to rely on the manual backup. Earlier troubles meant that spacecraft landed 386 km away from their targeted landing zome in the forests of Upper Kama Upland.
Low Earth OrbitThe Program 206 satellite, carrying the KH-7 (Keyhole 7) camera system (codenamed Gambit-1), was the first successful high resolution space reconnaissance program. It was managed by NRO's Program A, the USAF-led segment of the National Reconnaissance Program managed from Los Angeles AFB in El Segundo, California.
Sun-Synchronous OrbitThe Transit-O series of satellites that closely followed the design of Transit 5C-1 were also called “Oscars” (Oscar is the phonetic alphabet for “O”, i. e., operational). They were also called NNS (Navy Navigation Satellite) or shortened NavSat.
