One year ago, on Nov. 5, 2018, NASA’s Voyager 2 became only the second spacecraft in history to leave the heliosphere — the protective bubble of particles and magnetic fields created by our Sun. At a ...

Mission engineers at NASA have turned off the plasma science instrument aboard the Voyager 2 spacecraft due to the probe's gradually shrinking electrical power supply. Traveling more than 12.8 billion ...

The Voyager 2 spacecraft’s energy budget keeps dropping by about 4 Watt/year, as the plutonium in its nuclear power source is steadily dropping as the isotope decays. With 4 Watt of power less to use ...

This graphic shows the position of the Voyager 1 and Voyager 2 probes in relation to the protective bubble created by the sun that extends well past the orbit of Pluto. Voyager 1 crossed the ...

NASA has succeeded in re-establishing full contact with Voyager 2 by using its highest-power transmitter to send an "interstellar shout" that righted the distant probe's antenna orientation, the space ...

When NASA’s twin Voyager probes left Earth in 1977, they carried computers weaker than a hand calculator and a modest goal of touring the outer planets. No one seriously expected them to redraw the ...

After weeks of giving Earth the silent treatment, NASA's Voyager 2 spacecraft is once again communicating with mission control from billions of miles away. All it took was for the ground team to send ...

The venerable Voyager spacecrafts are now nearly 50 years old, and having headed out beyond the orbit of Pluto and into interstellar space, the pair are the most distant man-made objects in the ...
