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.
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.
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.
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 ...

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.
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.
communication - How does Voyager 1 send signals to Earth?
The radio communication system of Voyager 1 was designed to be used up to and beyond the limits of the Solar System during the extremely long flight of this space probe. The communication system includes a 3.7 meter diameter parabolic dish high-gain antenna to send and receive radio waves via the three Deep Space Network stations on the Earth.
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.

The Voyager program is an American scientific program that launched two unmanned space missions, the probes Voyager 1 and Voyager 2. Although they were designated officially to study just the planetary systems of Jupiter and Saturn, the space probes were able to continue their mission into the outer solar system, and they are expected to push ...
