Voyager 1 overtakes Pioneer 10 as the most distant spacecraft from the Sun, at 69.419 AU. Voyager 1 is moving away from the Sun at over 1 AU per year faster than Pioneer 10. 2004-12-17 Passed the termination shock at 94 AU and entered the heliosheath. 2007-02-02 Terminated plasma subsystem operations. 2007-04-11 Terminated plasma subsystem heater.
Voyager 1 was launched after Voyager 2, but along a shorter and faster trajectory that was designed to provide an optimal flyby of Saturn's moon Titan, [21] which was known to be quite large and to possess a dense atmosphere. This encounter sent Voyager 1 out of the plane of the ecliptic, ending its planetary science mission. [22]
The space probes Voyager 1 and Voyager 2 employ this method, and have used up about three quarters [4] of their 100 kg of propellant as of July 2015. Another method for achieving three-axis stabilization is to use electrically powered reaction wheels, also called momentum wheels, which are mounted on three orthogonal axes aboard the spacecraft.
Mission control on Earth receives that data in binary code, or a series of ones and zeroes. ... Initially designed to last five years, the Voyager 1 and its twin, Voyager 2, launched in 1977 and ...
Voyager 1’s flight data system is responsible for collecting information from the spacecraft’s science instruments and bundling it with engineering data that reflects the probe’s health status.
Of the 10 science instruments Voyager 1 started its journey with, four are currently gathering data on its cosmic environment, and each year, the spacecraft loses more of its precious power supply.
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 ...
