Voskhod programme

From Academic Kids

The Voskhod programme (Восход, translated as "Sunrise") was a Soviet human spaceflight project. It was a development of and a follow-on to the Vostok programme using the Voskhod spacecraft and rocket.

Achieving the first EVA ("spacewalk") was the main purpose of the programme, but beating the US Gemini program to put the first multi-person crew in orbit also became an important objective. Both were realised and the programme was then abandoned due to the EVA problems on Voskhod 2 and the need to concentrate on the Soyuz programme.

The Voskhod spacecraft was basically a Vostok spacecraft that had a backup, solid fuel retro rocket added to the top of the descent module. The heavier weight of the craft was made possible by improvements to the R7 derived booster. The ejection seat was removed and two or three crew couches were added to the interior at a 90 degree angle to that of the Vostok crew position. However the position of the in flight controls were not changed so the crew had to crane their heads 90 degrees to see the instruments. In the case of Voskhod 2, an inflatable exterior airlock was also added to the descent module opposite the entry hatch. After use, the airlock was jettisoned. There was no provision for crew escape in the event of a launch or landing emergency. A solid fuel braking rocket was also added to the parachute lines to provide for a softer landing at touchdown. This was necessary because, unlike the Vostok, the crew lands with the Voskhod descent module.

The Voskhod flights were:
