communication - How does Voyager 1 send signals to Earth?
WEBThe 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.
How does Voyager 1 keep track of its orientation?
WEBDec 5, 2017 · 9. 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.
Would a Voyager spacecraft trajectory change be recognized?
WEBApr 3, 2016 · Suppose Voyager 2 (Voyager 1 is moving faster and is further away, so the effect will be lesser on Voyager 1 than on Voyager 2) made a ridiculously close flyby of an object with a similar size and mass of Neptune. Such a flyby would result in a delta-V of about 8.2 km/sec. Suppose this delta-V is orthogonal to the line of sight to Earth (worst ...
spacecraft - Why is Voyager 1 faster than all other space probes ...
WEBAug 13, 2017 · 15. I can add one interesting bit about why Voyager 1 is going faster than Voyager 2. Voyager 1 had assists from Jupiter and Saturn, but Voyager 2 had assists from those and Uranus and Neptune. So you might think that Voyager 2 should have been accelerated more by the assists, and so should be going faster. Yet it's not.
history - Are the Voyager spacecrafts' X-band TWTAs currently set …
WEBThis is done 6 times a year for Voyager 1, Voyager 2 tape operations were ended in 2002. For Voyager 1, tape recorder operations will end in the next few years. Three times per week, Voyager 1 has 48 seconds of high rate (2.8 kbps) PWS data recorded onto the Digital Tape Recorder (DTR) for later playback. Voyager 1 has six playbacks per year.
history - What Voyager spacecraft hardware performed …
WEBJul 10, 2021 · The encoder for the spacecraft Voyager was a small and simple digital circuit, built with a 12 bit shift register and some logic. The 12 bit shift register was built from 3 shift registers with 4 bit each requiring 3 DIL chips with 16 pins. The logic was built with 6 half adders. One half adder needs two AND gates, one OR gate and one inverter.
Can Voyager still use its thrusters to avoid hazards?
WEBMar 11, 2020 · The Voyager spacecraft have no way to detect that they are on a collision course because the cameras that took all of those beautiful images were powered off a long time ago. Even if they spacecraft could see the imminent collision, the spacecraft have so little fuel left in them that nothing could be done to avoid that collision.
Why were the Voyager spacecraft numbered "out-of-order"?
WEB7. On MER we numbered the builds, but used letters for the launches. So MER-1 was built before MER-2. MER-A would both launch and arrive first, and MER-B would launch and arrive second. We weren't sure which hardware would launch first, and in fact due to how system testing on the two units was laid out, MER-2 became MER-A (Spirit), and MER-1 ...
How cold are the Voyagers now? Colder than LOX? Colder than …
WEBThe MHW-RTG model Radioisotope Thermoelectric Generators on the two Voyager spacecraft started out at about 1000C and 300C on the hot and cold sides, but will have dropped somewhat due to slow decay of the radioisotope thermal output.
For how long will the Voyager records remain playable?
WEBJun 8, 2014 · The disks on Voyager 1 and Voyager 2 (they are the same) are copper disks, plated in gold. The disks are encased in an aluminum housing to protect them from the "elements" of space. Barring any impacts with space rocks or other events like that, the records will last and be playable pretty much forever.
