SpaceShipOne has conducted two human suborbital spaceflights. The Orteig Prize inspired the $10 million Ansari X Prize for repeated suborbital private spaceflights. All crewed Russian spaceflights are launched from Baikonur. The programme carried out six crewed spaceflights between 1961 and 1963. Including Soyuz 34 gives a total of 329 attempted human spaceflights. Planned private spaceflights beyond Earth orbit include solar sailing prototypes (LightSail-3). The Vostok 3KA was the spacecraft used for the first human spaceflights. Planned private spaceflights beyond Earth orbit include personal spaceflights around the Moon. Plans announced thus far include sub-orbital and lunar spaceflights. Uncrewed visiting spacecraft are excluded (see Uncrewed spaceflights to the International Space Station for details). This program allows individuals to reserve seats on future orbital spaceflights. Fearing for his life, Soviet officials permanently banned Gagarin from further spaceflights. Jupiter-C was a sounding rocket used for three sub-orbital spaceflights in 1956 and 1957. The X-15 was flown by Joseph A. Walker, who flew both X-15 spaceflights. These six Apollo spaceflights are the only times humans have landed on another celestial body.
