Voyager 2 Contact Loss

NASA accidentally severs contact with Voyager 2 probe 12 billion miles from Earth

NASA has temporarily lost contact with the Voyager 2 probe — the second-farthest human made object from Earth in the universe, currently sailing through interstellar space roughly 12.3 billion miles (19.9 billion kilometers) from home.

According to a statement from NASA's Jet Propulsion Laboratory, scientists lost contact with the probe on July 21 after a series of planned commands inadvertently caused Voyager 2 to angle its antenna away from Earth by about two degrees. Unable to transmit or receive messages from NASA's Deep Space Network — an international array of large radio antennas that support many of NASA's interplanetary missions — Voyager 2 is essentially adrift and alone in the dark of space, having left the outer edge of our solar system in November 2018.

Luckily, the radio blackout should be temporary, NASA said. Voyager 2 is programmed to reset its antenna's alignment several times each year to stay in contact with Earth as it drifts ever farther away. The next reset is scheduled for Oct. 15, at which point communication with Voyager 2 should resume.



Such jaunty reporting in this one, but I think NASA's actual statement sounded a lot less optimistic about the reset fixing the problem.

Calling occupants of interplanetary craft...

Why do you say the NASA statement sounds less jaunty? It says "The next reset will occur on Oct. 15, which should enable communication to resume": almost exactly the same as the livescience report. One hopes that Voyager will be able to find Earth by waving its antennae around a bit and seeing what comes back out of the void.

It will be Oct. 16th, though, by the time Voyager's signal reaches Earth (more than a lightday away by now).

As an expression of possibility, it's the least certain phrasing, whereas the article says twice it's a temporary situation, and even suggests this is a sufficiently certain as to warrant being considered lucky.

Either which way, at the moment, we gone lost it.

Inspired by the BBC report, which says that signals currently take more than 18 hours to reach Earth from Voyager 2, I've re-calculated it using Excel rather than in my head - and used the distance to the correct Voyager, which also helps - and I agree with the BBC: it's not quite a lightday away yet.

If you think it's a long way to the chemist's, that's nothing compared to the universe.

It's always nice when an estranged couple makes up.

Long distance relationships are hard.

She said she was popping to the chemist, but that was 45 years ago.

Nothing to do with the immediate subject of this thread, but:






It's a bit annoying ("brave spacecraft" - don't be silly), and I don't know that I believe that the solar wind "ebbs and flows". Still, it was an interesting listen.

The "impossible discovery", by the way, was that at the heliopause, when crossing into interstellar space, the observed magnetic field doesn't show any abrupt change. And I agree, I would have expected that it would.

EDIT: I see you're going to have to click on the link and watch it on YouTube. Sorry about that.

AI narration too I think. Still, the Voyageurs are awesome.

Yep, at 14:48 the narrator says "twenty four sevenths" instead of 24/7, so likely AI narration.
