Voyager 2: Nasa fully back in contact with lost space probe

Nasa is backmost successful afloat interaction with its mislaid Voyager 2 probe months earlier than expected, the abstraction bureau said.

In July a incorrect bid was sent to the spacecraft, sent to research abstraction successful 1977, changing its presumption and severing contact.

A awesome was picked up connected Tuesday but acknowledgment to an "interstellar shout" - a almighty acquisition - its antenna is present backmost facing Earth.

Nasa had primitively pinned hopes connected the spacecraft resetting itself successful October.

It took 37 hours for ngo controllers to fig retired if the interstellar bid had worked arsenic Voyager 2 is billions of miles distant from Earth.

After communications were lost, the probe had been incapable to person commands oregon nonstop backmost information to Nasa's Deep Space Network - an array of elephantine vigor antennas crossed the world.

But the abstraction bureau confirmed connected 4 August that information had been received from the spacecraft and was operating normally.

Nasa expects the spacecraft laden with subject instruments to stay connected its planned trajectory done the universe.

On Monday, the abstraction bureau said its immense crockery successful Australia's capital, Canberra, was trying to observe immoderate stray signals from Voyager 2.

The antenna had been bombarding Voyager 2's country with the close command, successful the anticipation of someway making contact, Nasa's Jet Propulsion Laboratory, which manages the Voyager missions, said.

The probe is programmed to reset its presumption aggregate times each twelvemonth to support its antenna pointing astatine Earth. The adjacent reset is owed connected 15 October, which Nasa had rested its hopes connected if each different attempts had failed.

Voyager 2 and its duplicate Voyager 1 are the lone spacecraft ever to run extracurricular the heliosphere, the protective bubble of particles and magnetic fields generated by the Sun. They and 2012 respectively.

The probes were designed to instrumentality vantage of a uncommon alignment of outer planets, which occurs astir each 176 years, to research Jupiter and Saturn.

Voyager 2 is the lone spacecraft ever to alert by Neptune and Uranus, portion Voyager 1 is present astir 15 cardinal miles distant from Earth, making it humanity's astir distant spacecraft.

Once some spacecraft tally retired of powerfulness - expected sometime aft 2025 - they volition proceed roaming done space.
