NASA hears signal from Voyager 2 spacecraft after mistakenly cutting contact
Flight controllers accidentally sent a wrong command nearly two weeks ago that tilted the spacecraft's antenna away from Earth and severed contact.
CAPE CANAVERAL, Fla. (AP) — After days of silence, NASA has heard from Voyager 2 in interstellar space billions of miles away.
Flight controllers accidentally sent a wrong command nearly two weeks ago that tilted the spacecraft’s antenna away from Earth and severed contact.
NASA’s Deep Space Network, giant radio antennas across the globe, picked up a “heartbeat signal,” meaning the 46-year-old craft is alive and operating, project manager Suzanne Dodd said in an email Tuesday.
The news “buoyed our spirits,” Dodd said. Flight controllers at the Jet Propulsion Laboratory in California will now try to turn Voyager 2’s antenna back toward Earth.
If the command doesn’t work — and controllers doubt it will — they’ll have to wait until October for an automatic spacecraft reset. The antenna is only 2% off-kilter.
“That is a long time to wait, so we’ll try sending up commands several times” before then, Dodd said.
Voyager 2 rocketed into space in 1977, along with its identical twin Voyager 1, on a quest to explore the outer planets.
Still communicating and working fine, Voyager 1 is now 15 billion miles (24 billion kilometers) from Earth, making it the most distant spacecraft.
Voyager 2 trails its twin in interstellar space at more than 12 billion miles (19 billion kilometers) from Earth. At that distance, it takes more than 18 hours for a signal to travel one way.
You're viewing a single thread.
Ahh I can only imagine how crappy you would feel after sending the wrong comand. Hopefully they can get it back.
Being in IT I've made a LOT of mistakes over the years, it comes with the territory. Though potentially screwing up a nearly half-century old science mission is not one of those. I truly hope for everyone's sake (but especially the person/people that issued the wrong command) that everything is corrected come October. That would be a horrible thing to have to think about.
Same here. At least when I screw something up I can at least walk/drive/fly to the faulty device. 12 Billion miles is a long way to go to press the reset button.
Try day trading futures on margin, put a comma in the wrong place, see a great prediction and strategy go down the drain... and now it's in the past, gone forever.
I think it must feel similar.
Ouch :(.
They will by October, since the whole reason for regularly resetting is in case something like this occurs.
At least there is that.
