On 21 July, flight controllers in Pasadena, California, uplinked a collection of instructions that inadvertently triggered the Voyager 2 spacecraft to intention itself and its high-gain antenna at a degree in area 2 levels away from Earth. Since then, the probe has been incommunicado, unable to obtain instructions or beam telemetry and science information to the bottom.
Whereas the misalignment is comparatively minor, at Voyager 2’s distance from Earth – 19.9 billion kilometres, or 12.4 billion miles – it’s greater than sufficient to maintain the spacecraft’s more and more weak sign, lower than a billionth of a billionth of a watt by the point it reaches Earth, from hitting NASA’s Deep Area Community antennas.
To not fear. NASA says Voyager 2 is programmed to reset its orientation a number of occasions a 12 months to maintain its antenna exactly aimed. The subsequent reset is predicted on 15 October, when flight controllers can be standing by to renew two-way communications. Spherical-trip journey time for indicators to and from Voyager 2: about 37 hours.
Launched in 1977, Voyager 1 departed the photo voltaic system after flybys of Jupiter and Saturn. Voyager 2 adopted swimsuit after flybys of Jupiter Saturn, Uranus and Neptune. Each have departed the photo voltaic system and at the moment are crusing via interstellar area, racing away from the Solar at greater than 54,700 kph (34,000 mph).
