NASA reestablished contact with its STEREO-B spacecraft on Sunday, almost two years after losing communication with it Oct. 1, 2014.
The spacecraft is part of NASA’s Solar Terrestrial Relations Observatory (STEREO), which aims to study the sun and space weather.
NASA used its Deep Space Network, which tracks and communicates with missions throughout space, to receive a signal from STEREO-B. Scientists lost contact with it after intentionally resetting the spacecraft in 2014 in order to angle its antenna away from the sun because it risked being overheated, the Verge reported.
The STEREO-A spacecraft continues to function normally, NASA said.
