After losing communication with a space probe two years ago, NASA says it has reestablished contact
NASA said it lost contact with the Solar Terrestrial Relations Observatories, known as the STEREO-B spacecraft, on Oct. 1, 2014, but that on Aug. 21, the Deep Space Network (DSN) established a link with the craft
Contact with the probe was lost after a maneuver to try to prevent overheating of the ship’s antenna
STEREO-B is the sister craft to STEREO-A, both of which were launched in 2006 to study the sun and space weather. The spacecrafts have contributed greatly to the understanding of coronal mass ejections, a bubble of super-heated gas and charged particles blasted into space from the sun’s upper atmosphere, the corona
NASA said it will now have to test STEREO-B to see how instrumentation and other sensors are operating after two years
