sunlight - How bright is the sun now, as seen from Voyager?
2024年12月9日 · The inner Solar System looks quite small from Voyager's POV. So the inner planets are always within a degree or so of the Sun. Here's a plot for the current year (with a 5 day timestep) of the ecliptic longitude & latitude of the Sun, Earth, and Jupiter, as seen from Voyager 1. The lon-lat plotting script may be found here.

2024年12月5日 · Voyager 1 (Mariner 11), 1977: - >47 years, still going - RTG Now, I'm cherry-picking, showing only stuff from the US NASA's own probes, and omitting any non-interplanetary spacecraft which lacked RTG.
Why is Voyager 1 faster than all other space probes?
2017年8月13日 · Although other probes were launched first, Voyager 1 was able to achieve a higher speed and has overtaken all others. Voyager 1 overtook Voyager 2 a few months after launch, on 19 December 1977. It overtook Pioneer 11 some time in the late 1980s, and then Pioneer 10—becoming the probe farthest from Earth—on February 17, 1998.
attitude - How does Voyager 1 keep track of its orientation?
2017年12月5日 · Voyager 1 and Voyager 2 use the same Attitude and Articulation Control Subsystem (AACS) to maintain the crafts orientation; facing the antenna towards the Earth. Voyager's AACS system uses a sun sensor for yaw and pitch reference, and a star tracker trained continuously on a bright star at right angles to the sun point for a roll reference.
Are the Voyager probes radio output power scalable? - Space …
2019年5月7日 · Limits for the third site, near Madrid, Spain, are similar to those at Goldstone for Voyager 1. Voyager contin(u)ously reviews, updates, and consolidates processes in order to increase efficiency and improve its return on public investment. During VIM, Voyager has reduced its flight team staffing by 97%, from approximately 300 in 1989 to 10 in ...
probe - How was magnetic tape decay prevented in Voyager 1?
Voyager's flange basically works on the same principle, but I knew it had to be designed to last a very long time. Viking's life was short by comparison. Voyager? I planned on an infinite life. Yeah, you're right: the "flange" on Voyager looks like a solid piece of metal attached to the top of the tape reel. Well, actually, not exactly.
What does it mean when the Voyagers "switch thrusters"?
2019年7月15日 · Voyager 1 and Voyager 2 are each equipped with six sets, or pairs, of thrusters to control their movement. These include three pairs of primary thrusters and three backup, or redundant, pairs. Voyager 2 is currently using the two pairs of backup thrusters that control the pitch and yaw motion of the spacecraft.
Do the Voyager space probes perform time synchronization …
Voyager 1 travels at a velocity relative to the Sun of 19.03 km/s (or 0.000063478 c, or a time difference of ~ 0.0005 seconds per year), and Voyager 2 travels at 15.428 km/s. According to the factsheet , Voyagers do not have a time synchronization system on board, atomic clock or something like that.

2023年9月28日 · The Deep Space Network uses massive dish antennas for uplink -- the dishes are 26, 34, and 70 meters (for various purposes), sited in California, Spain, and Australia. So hijacking a space probe is outside the reach of individual pranksters, but possibly within the capabilities of a competing nation with its own massive transmission dishes.
mission end - Will NASA abandon the Voyager spacecraft? - Space ...
2022年9月23日 · The fictional Voyager 6 probe around which V'ger was built, was actually a full-scale mock-up of the real world Voyager 1 and 2 probes of NASA's Jet Propulsion Laboratories (JPL). JPL's director John Casani agreed to loan the model to the studio in October 1977, mere months after the actual Voyager probes were launched in August and September ...
