Voyager 2 was also to explore Jupiter and Saturn, but on a trajectory that would have the option of continuing on to Uranus and Neptune, or being redirected to Titan as a backup for Voyager 1. Upon successful completion of Voyager 1's objectives, Voyager 2 would get a mission extension to send the probe on towards Uranus and Neptune. [13]
The Voyager primary mission was completed in 1989, with the close flyby of Neptune by Voyager 2. The Voyager Interstellar Mission (VIM) is a mission extension, which began when the two spacecraft had already been in flight for over 12 years. [50]
NASA sent a radio signal to Voyager 2, located billions of miles away in interstellar space, and restored communications with the spacecraft after an errant command caused a blackout.
If undisturbed for 296,000 years, Voyager 2 should pass by the star Sirius at a distance of 4.3 light-years. [5] Voyager 1 – launched in September 1977, flew past Jupiter in 1979 and Saturn in 1980, making a special close approach to Saturn's moon Titan. The probe passed the heliopause at 121 AU on August 25, 2012, to enter interstellar space ...
An image of the planet Uranus taken by the NASA spacecraft Voyager 2 in 1986. New research using data from the mission shows a solar wind event took place during the flyby, leading to a mystery ...
The plasma experiment had been gathering limited data. NASA expects the Voyager 2 spacecraft will continue operating with other experiments into the 2030s.
Voyager 2 is now floating on its own, almost 20 billion kilometres from Earth. Nasa still hopes to be able to re-establish contact with the probe, however. It is programmed to automatically reset ...
Voyager 1 entered interstellar space in 2012. [28] As of January 19, 2019, Voyager 1 was at a distance of 145.148 AU (13.492 billion miles (21.713 × 10 ^ 9 km)) from Earth, traveling away from the Sun at a speed of about 10.6 mi/s (17.1 km/s), which corresponds to a greater specific orbital energy than any other probe.
