Thereafter, "Pioneer 10" became the first of five artificial objects to achieve the escape velocity that will allow them to leave the Solar System. This space exploration project was conducted by the NASA Ames Research Center in California, and the space probe was manufactured by TRW Inc. "Pioneer 10" was assembled around a hexagonal bus with a diameter parabolic dish high-gain antenna, and the spacecraft was spin stabilized around the axis of
Space probe (first weather balloons deployed on another planet) at Venus before their rendezvous with Halley's Comet. This Japanese probe was the first non-US, non-Soviet interplanetary probe. A second Japanese probe, it made ultraviolet wavelength observations of the comet. The first space probe to penetrate a comet's coma and take close-up images of its nucleus. First solar wind sample return probe from sun-earth L1. First sample return probe from a comet tail. First probe to land on an asteroid. First sample return probe to launch from an asteroid. The Rosetta space probe flew by two asteroids and made a rendezvous and orbited
