Voyager 2: NASA restores communication with the spacecraft after two weeks of technical glitch

NASA has finally managed to reestablish contact with the Voyager 2 spacecraft following two weeks of silence after flight controllers sent a wrong command to the spacecraft that titled its antenna away from earth.To reposition the antenna, NASA's Deep Space Network sent an "interstellar shout" on Wednesday with the help of NASA's most powerful radio antenna in Canberra, Australia.

It was a longshot attempt at sending instructions to right the craft that required perfect timing.

The command was timed to be sent during the best conditions during the antenna tracking pass in order to maximize possible receipt of the command by the spacecraft.

As Voyager 2 is more than 12 19 billion kilometers from earth, it took roughly 18.5 hours for the command traveling at light speed to reach the spacecraft, and another 18.5 hours to hear back.

Crews therefore had to wait more than a day to learn whether their intervention had even worked.

In the early hours of yesterday in the US, Voyager began returning science and telemetry data "indicating it is operating normally and that it remains on its expected trajectory," the Jet Propulsion Laboratory said.

Astronomers Witness Merger of 2 Black Holes From the 'Cosmic Dawn'

Astronomers Witness , Merger of 2 Black Holes, From the 'Cosmic Dawn'. 'The Independent' reports that NASA's Webb Space Telescope has made the most distant detection of merging black holes. . Two gigantic black holes and the galaxies that they stood at the center of merged together just 740 million years after the universe was formed in the Big Bang. One of the black holes is a staggering 50 million times larger than our Sun, and the other is believed to be a similar gigantic size. . Astronomers have long wondered how supermassive black holes are so big. . Lead author Hannah Ubler of the University of Cambridge says the findings suggest that mergers like this ancient example show how black holes are able to grow so rapidly. According to Ubler, the latest Webb discovery also suggests that black holes have been merging since the "cosmic dawn.". Massive black holes have been shaping the evolution of galaxies from the very beginning, Hannah Ubler, lead author from the University of Cambridge, via 'The Independent'. In 2021, NASA launched Webb, intended to replace the Hubble Space Telescope. Webb is the largest and most powerful observatory ever launched into space. . The joint U.S.-European project surveys the universe from a vantage point located about 1 million miles away from Earth.
