Voyager 2 view of Enceladus in 1981: Samarkand Sulci vertical grooves (lower center); Ali Baba and Aladdin craters (upper left). Enceladus Life Finder (ELF) is a proposed astrobiology mission concept for a NASA spacecraft intended to assess the habitability of the internal aquatic ocean of Enceladus, which is Saturn's sixth-largest moon [1] [2] of at least 146 total moons, and seemingly ...
The Double Asteroid Redirection Test (DART) was a NASA space mission aimed at testing a method of planetary defense against near-Earth objects (NEOs). [4] [5] It was designed to assess how much a spacecraft impact deflects an asteroid through its transfer of momentum when hitting the asteroid head-on. [6]
Breakthrough Starshot is a research and engineering project by the Breakthrough Initiatives to develop a proof-of-concept fleet of light sail interstellar probes named Starchip, [1] to be capable of making the journey to the Alpha Centauri star system 4.34 light-years away. It was founded in 2016 by Yuri Milner, Stephen Hawking, and Mark ...
NASA space observatory poised to launch on a mission to map 450 million galaxies. A new NASA space observatory, called SPHEREx, is scheduled to launch into orbit Thursday on a mission to map more ...
A next generation of infrared space telescopes began when NASA's Wide-field Infrared Survey Explorer launched on 14 December 2009 aboard a Delta II rocket from Vandenberg Air Force Base. Known as WISE, the telescope provided results hundreds of times more sensitive than IRAS at the shorter wavelengths; it also had an extended mission dubbed ...
Sun–Earth L 1: ESA, NASA: Orbiting near L 1 since 1996. Operational as of 2020. [27] WIND: Sun–Earth L 1: NASA: Arrived at L 1 in 2004 with fuel for 60 years. Operational as of 2019. [28] Wilkinson Microwave Anisotropy Probe (WMAP) Sun–Earth L 2: NASA: Arrived at L 2 in 2001. Mission ended 2010, [29] then sent to solar orbit outside L 2. [30]
Deep Space 1 (DS1) was a NASA technology demonstration spacecraft which flew by an asteroid and a comet. It was part of the New Millennium Program , dedicated to testing advanced technologies. Launched on 24 October 1998, the Deep Space 1 spacecraft carried out a flyby of asteroid 9969 Braille , which was its primary science target.
Pioneer 1, television camera; Pioneer 2, television camera; Lunar Orbiter program, Lunar Orbiter 1–5, 1966–1967; The camera used two lenses to simultaneously expose a wide-angle and a high-resolution image on the same film. The wide-angle, medium resolution mode used an 80 mm F 2.8 Xenotar lens manufactured by Schneider Kreuznach, Germany ...
