  1. No, that's not true. Earth's rotation makes things a bit more complicated, but it's not impossible. When we send data to Voyager, we aim an antenna at Voyager, start sending the data, and we keep the antenna aimed at Voyager. This can be done for up to 8 hours, then Earth's rotation puts the spacecraft below the horizon. So we have to make sure our transmissions take less than 8 hours. The Voyagers send science data continuously. We listen for up to 8 hours per session (and generally, each Voyager gets one 8-hour downlink session per day). If we want to receive engineering data, we have to tell the Voyager to send it at a specific time so we can schedule a downlink session.

  2. Yep. Space is empty.

  3. Adults follow the evidence that shows Voyager is a real project. Nobody has presented any evidence that these missions were faked.

  4. It takes 22.5 hours for a radio signal to reach Voyager 1, just as long as it takes a photon of light to reach Voyager 1. Radio signals (like everything in the electromagnetic spectrum) travel at the speed of light.

  5. Budget cuts ended the Voyager program. But the successor to the Voyagers were missions that would spend years orbiting one planet: Galileo and Juno at Jupiter, Cassini at Saturn.

  6. The link to Voyager isn't wifi, obviously. Wifi and cellular phone systems are radio systems designed to work at short distances. The smaller a cell, the more subscribers you can service in a certain area. Radio is not magic. Radio waves do not travel through solid obstacles. Between Voyager and Earth, there are no solid obstacles. The radio link is exclusive: only Voyager and its ground station talk to each other. The ground station for Voyager uses the same technology as radio telescopes: giant dish antennas, and cryogenically cooled receivers that can receiver Voyager's very weak signals. We can calculate the maximum distance at which this radio link should be able to contact the Voyagers. That distance is around 200 AU. Voyager 1 is at a distance of 150 AU now, so they're good for another 25 years.

  7. Your phone loses signal because there are walls between you and the cell tower. No walls in space.

  8. Nonsense is believing the Voyager missions were faked, with no evidence to back up those absurd claims.

  9.  @antontsoai9138  Voyager observations of the planets have since been confirmed by terrestrial telescopes. Radio telescopes occasionally track the Voyagers. So, sources independent from the organization that runs the Voyagers confirm the reality of this mission. Again, you are presenting no evidence that these missions are faked. Without evidence, your claims are worthless.

  10. The Apollo program sent 9 missions out of low Earth orbit to the moon. And one of the Gemini missions went into the van Allen belts. Kelly Smith (the Orion engineer you're referring to) never claimed that Apollo did not get out of low Earth orbit. His challenge was to design Orion, and make sure IT was safe for humans by doing an unmanned test before putting humans on board.

  11. You can look up tonight and see satellites in space, proving that space is real.

  12.  @Heracles_FE  If NASA is a mind control operation, why do they keep running real, verifiable missions?

  13. Only the ignorant call the Voyager missions bullshit.

  14.  @dune8998  a few of your replies have been eaten by Youtube's spam filter. Don't put links into posts.

  15.  @dune8998  Radiation, at the levels present in space, does not affect radio waves. The only thing you need to communicate across such distances is a large antenna. NASA operates the largest radio antennas in the world.

  16. We can easily measure the distance to the moon, and find that it's at 380,000 km, not 100. We know what plasma looks like. The sun is an example. Notice how bright it is? Now look at the new moon, and see that it does not produce light.

  17. No, it doesn't make its own fuel. It just uses very little. All it has to do is adjust the way it's pointing its antenna, and that can be done with tiny amounts of fuel.

  18. you need a bunch more zeroes in that number to get to the edge of the universe. The Voyagers haven't left our solar system yet.

  19. We know it upgraded because we can communicate with the spacecraft: we send a radio signal, it sends data back. By the 1970s, we knew how to radiation-harden integrated circuits.

  20. No, JPL says no such thing. From the Voyager Mission Status page 2023-12-31: one way light time for Voyager 1 is 22h 35min, Voyager 2 is 18:52.

  21. Actual experience with modern deep-space missions proves you wrong.

  22. False. We know exactly how to get to the moon, and we're in the middle of building two different lunar landers.

  23. Anyone can verify that satellites are real, just by looking up at the night sky. This proves that space isn't fake, which collapses your entire argument like a bad soufflé.

  24. Our cell phone system is designed with limited range, because the more range you have, the fewer phones you can handle in the network. There's no such constraint for the radio link with Voyager: it has a dedicated link and we can use huge antennas to amplify the signal.

  25. Sensors still operational on both: Cosmic Ray Subsystem, Low-Energy Charged Particles, Magnetometer, Plasma Wave Subsystem, Plasma Science (PLS) on Voyager 1 only. Data from most instruments is sent live from the spacecraft to Earth, and we receive this data for about 8 hours per day. Only the PLS instrument records data on the onboard tape recorder for later playback.

  26. yes. The program is uploaded, then checked, before they switch from the old to the new software.

  27. You lose phone reception because of all the buildings between you and the cell tower, and the thousands of other cell users in the area. There are no obstacles between us and the Voyagers, and no shared radio link either.

  28. The Voyagers currently communicate at 160 bits per second.

  29.  @Heracles_FE  I'm an electronics engineer. I know what it takes to receive such weak signals. It's pretty simple to calculate, using a link budget. NASA's 70 meter antennas with receivers cooled to 4 K are more than capable enough to receive Voyager's signals. And we have independent confirmation: radio astronomers occasionally track the Voyagers. More independent confirmation comes from the fact that the Voyager observations of the planets have been replicated with telescopes on Earth.

  30.  @Heracles_FE  Operation Paperclip is no secret. About 200 rocket scientists were brought to the US and were put to work developing rockets, as it was clear that rockets were the next big development in warfare.

  31. About 100 kg. Most of the propellant was in the rocket that launched it (more than 600 tons).

  32. We already have spacecraft orbiting the moon that have mapped the entire surface including the far side. Luna 2 was the first to take photos of the far side, in 1959 IIRC. Since then, Lunar Orbiter and Lunar Reconnaissance Orbiter have done full maps. Chandrayaan-2 and Chang'e 2 are on mapping missions now.

  33.  @robertnorman4306  All of the photos I mentioned are available in public archives. They all show the same thing: the far side of the moon is similar to the near side, the only difference is there are more craters and fewer maria. There is no "cover up".

  34. We're in contact with both Voyagers every day, and every contact allows us to verify their position. They're on entirely predictable trajectories, so even after years of no contact you'd be able to find it in one try.
