During the 1950s and 1960s the Soviet space program used dogs for sub-orbital and orbital space flights to determine whether human spaceflight was feasible. These dogs, including Laika, the first animal to orbit Earth, were surgically modified to provide the necessary information for human survival in space.
Profile for the first crewed American sub-orbital flight, 1961. Launch rocket lifts the spacecraft for the first 2:22 minutes. Dashed line: zero gravity. Science and Mechanics cover of November 1931, showing a proposed sub-orbital spaceship that would reach an altitude 700 miles (1,100 km) on its one hour trip from Berlin to New York.
An orbital spaceflight (or orbital flight) is a spaceflight in which a spacecraft is placed on a trajectory where it could remain in space for at least one orbit. To do this around the Earth , it must be on a free trajectory which has an altitude at perigee (altitude at closest approach) around 80 kilometers (50 mi); this is the boundary of ...
Falcon 9 Block 5, the most prolific active orbital launch system in the world. This comparison of orbital launch systems lists the attributes of all current and future individual rocket configurations designed to reach orbit. A first list contains rockets that are operational or have attempted an orbital flight attempt as of 2024; a second list ...
The proposed flight schedule included a first sub-orbital test flight (SARA Suborbital 1) in 2014 [3] [4] using a VS-40 rocket launched from the Centro de Lançamento da Barreira do Inferno (Operação São Lourenço). [4]
Soviet rocket engineers had long intended a canine orbit before attempting human spaceflight; since 1951, they had lofted 12 dogs into sub-orbital space on ballistic flights, working gradually toward an orbital mission set for some time in 1958. To satisfy Khrushchev's demands, they expedited the orbital canine flight for the November launch. [3]

Spaceflight (or space flight) is an application of astronautics to fly objects, usually spacecraft, into or through outer space, either with or without humans on board.Most spaceflight is uncrewed and conducted mainly with spacecraft such as satellites in orbit around Earth, but also includes space probes for flights beyond Earth orbit.
