Unmanned NASA missions evaporation. The supply of liquid helium was depleted on November 21, 1983, preventing further observations. The spacecraft continues to orbit close to the Earth. The telescope was a joint project of the United States (NASA), the Netherlands (NIVR), and the United Kingdom (SERC). Over 250,000 infrared sources were observed at 12, 25, 60, and 100 micrometer wavelengths. The Magellan spacecraft was a space probe sent to the planet Venus, the first unmanned interplanetary spacecraft to be launched by NASA since its successful Pioneer Orbiter, also to Venus, in 1978. It was also the first deep-space probe to be launched on
Space probe far layers of our heliosphere, thus concluding the craft had broken beyond the heliopause. Voyager 2 was launched by NASA on August 20, 1977. The probe's primary mission was to visit the ice giants, Uranus and Neptune, which it completed on October 2, 1989. It is currently the only probe to have visited the ice giants. It is the fourth of five spacecraft to have left the solar system. It has been operational for 41 years and 2 months as of October 20, 2018. Cassini–Huygens was a 5,712kg (12,593lb) space probe designed to study gas giant Saturn, along with its
