Sputnik 1 and Gagarin
This page delivers no verdict; it presents claims and evidence with their sources. No theory in science is absolute. Method
For everyone
On 4 October 1957 the Soviet Union launched the first artificial satellite, Sputnik 1. On 12 April 1961 Yuri Gagarin orbited the Earth once in Vostok 1, becoming the first human in space. These achievements accelerated the founding of NASA and the goal of reaching the Moon in the US.
For specialists
Sputnik 1 was an 83.6 kg sphere with four antennas broadcasting at 20 and 40 MHz, launched on an R-7 intercontinental missile. The Vostok 1 flight lasted about 108 minutes; Gagarin ejected from the capsule during descent and landed by parachute, a detail not disclosed for years for reasons related to the flight-record rules of the time.
Claims
- A human-made object can be placed in Earth orbit, and a human can survive spaceflight.[1]
