NASA launched the Solar Terrestrial Relations Observatory B (STEREO-B) spacecraft in 2006 to gather data about solar phenomena as it orbited the sun. In October 2014, the craft went missing in action when it failed to send any signal back to Earth. But now, 22 months later, NASA has found its lost spacecraft, The Washington Post reports. The space agency received a signal ping from STEREO-B Sunday evening and believes it lost contact when STEREO-B fell into a different orbit behind the sun, which interfered with any signal the craft might have sent. Further communication is needed to determine the craft’s health and ability to collect more data.
