Space exploration
For everyone
Humanity placed the first artificial satellite, Sputnik, in orbit in 1957; the first human went to space in 1961 and the first people walked on the Moon in 1969. The Voyager probes crossed the edge of the solar system, and the James Webb Telescope imaged the early universe. In April 2026 the Artemis II crew flew around the Moon and set a new record for the farthest humans have travelled from Earth.
For specialists
The basic equation of rocket motion is due to Tsiolkovsky (1903); Δv = vₑ ln(m₀/m_f) sets the fuel cost of reaching orbit and beyond. Reusable rockets (the Falcon 9 first stage from 2015) significantly lowered the cost per kilogram to orbit.
Claims
- The space race was waged between the US and the Soviet Union as part of the Cold War.[1]
