NASA Re-establishes Contact With Lost Craft After Two Years

Their STEREO is working again!

Back in STEREO

STEREO is actually a pair of spacecraft orbiting the sun 180 degrees apart. They form right angles to the Earth-sun line, and their combined observations were meant to give a 360 degree view of the sun for the first time. That is until STEREO-B went offline in October 2014.NASA/STEREO

After nearly two years, NASA has re-established contact with the other partner of a two-craft mission to study the sun.

Engineers lost contact with one of the two STEREO (Solar and Terrestrial Relations Observatory) craft back in October of 2014. The vessels are on opposite sides of the sun as part of an ongoing mission to learn more about the relationship between the earth and sun.

STEREO-B, which is 189-million miles away and on the other side of the sun, has a lot of tests to run through to see what went wrong, whether it's still functional, and plenty more. But hearing from it is a great start.
