Later flew past Saturn, Uranus and Neptune. Oldest active space probe at 47 years, 6 months, 6 days. Currently studying interstellar medium. At a distance of 136.1 AU (20.4 billion km; 12.7 billion mi) from Earth as of May 2024 [9] 4 Voyager 1: Voyager 1: 5 September 1977 [2] Titan IIIE Centaur-D1T [8] NASA: Flyby Successful
The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
Since then, increasingly distant planets have been reached, with probes landing on or impacting the surfaces of Venus in 1966 , Mars in 1971 (Mars 3, although a fully successful landing didn't occur until Viking 1 in 1976), the asteroid Eros in 2001 (NEAR Shoemaker), Saturn's moon Titan in 2004 , the comets Tempel 1 (Deep Impact) in 2005, and ...
Telescope data may have helped researchers figure out why. Four years ago, astronomers noticed the abundant clouds on Neptune had largely disappeared. Telescope data may have helped researchers ...
Voyager 2 started taking navigation images of Neptune in May 1988. [3] Voyager 2 's observation phase proper of Neptune began 5 June 1989, the spacecraft officially reached the Neptunian system on 25 August, and data collection ceased on 2 October. [4] Initially it was planned to use a trajectory that resulted in Voyager 2 passing around 1,300 ...
At times it is actually closer to the sun than Neptune. It has a methane, nitrogen and carbon monoxide atmosphere and a surface temperature of minus 378 to minus 396 degrees, too cold to sustain life.
“We have discovered that next step on a pathway to life.” This mosaic image of asteroid Bennu, was taken on December 2, 2018 by the OSIRIS-REx spacecraft from a range of 15 miles.
The Great Dark Spot in exaggerated color as seen from Voyager 2. The Great Dark Spot (also known as GDS-89, for Great Dark Spot, 1989) was one of a series of dark spots on Neptune similar in appearance to Jupiter's Great Red Spot. In 1989, GDS-89 was the first Great Dark Spot on Neptune to be observed by NASA's Voyager 2 space probe.
