The Multihundred-watt radioisotope thermoelectric generator (MHW RTG) is a type of US radioisotope thermoelectric generator (RTG) developed for the Voyager spacecraft, Voyager 1 and Voyager 2. [1] The Voyager generators continue to function more than 45 years into the mission. [2] Radioisotope thermoelectric generators for the Voyager program.
On March 5, 1979, Voyager 1 performed the closest encounter with Io of the Voyager mission from a distance of 20,600 km (12,800 mi) over its south pole. [ 46 ] [ 48 ] The close distance of the encounter allowed Voyager to acquire images of the sub-Jovian and south polar regions of Io with a best resolution of less than 0.5 km (0.3 mi) per pixel ...
Volcanism on Io, a moon of Jupiter, is represented by the presence of volcanoes, volcanic pits and lava flows on the surface. Io's volcanic activity was discovered in 1979 by Linda Morabito, an imaging scientist working on Voyager 1. [1] Observations of Io by passing spacecraft and Earth-based astronomers have revealed more than 150 active ...
Io (/ ˈ aɪ. oʊ /), or Jupiter I, is the innermost and second-smallest of the four Galilean moons of the planet Jupiter.Slightly larger than Earth's moon, Io is the fourth-largest moon in the Solar System, has the highest density of any moon, the strongest surface gravity of any moon, and the lowest amount of water by atomic ratio of any known astronomical object in the Solar System.
Map of the surface of Io, based on images from the Galileo and Voyager missions.. Mountains are widely distributed across the surface of Io.There are about 115 named mountains; the average length is 157 km (98 mi) and the average height is 6,300 m (20,700 ft).
Voyager 1 has been using the X-band transmitter for decades, but the S-band hadn’t been employed since 1981 because its signal is much fainter than the X-band’s. The team had to seek out the ...
The Voyager 1 spacecraft is sending back a steady stream of scientific data from uncharted territory for the first time since a computer glitch sidelined the historic NASA mission seven months ago.
Voyager 1 used the thrusters for a variety of purposes as it flew by planets such as Jupiter and Saturn in 1979 and 1980, respectively. Now, the spacecraft is traveling on an unchanging path away ...
