Nasa’s flight controllers will likely be celebrating tonight, after correcting a mistake that had led to weeks of silence from Voyager 2.
Launched on August 20, 1977, the space probe is currently 12.3 billion miles from Earth, roaming interstellar space and reporting back on its finds.Controllers sent the wrong command to the 46-year-old spacecraft and tilted its antenna away from Earth.
On Wednesday, NASA’s Deep Space Network sent a new command in hopes of repointing the antenna, using the highest powered transmitter at the huge radio dish antenna in Australia.It took more than 18 hours for the command to reach Voyager 2 — more than 12 billion miles away — and another 18 hours to hear back.
On Friday, the spacecraft started returning data again, according to officials at California’s Jet Propulsion Laboratory. Voyager 2 has been hurtling through space since its launch in 1977 to explore the outer solar system. Launched two weeks later, its twin, Voyager 1, is now the most distant spacecraft — 15 billion miles away — and still in contact.
