But STEREO-B will soon emerge from the Sun’s interference zone, and spacecraft operators will resume their attempts to contact the spacecraft on Nov. ![]() For several months, STEREO-B’s orbit took it behind the Sun from our perspective, making it impossible to send messages to the spacecraft. STEREO-A’s twin spacecraft, STEREO Behind, has been out of communication since October 2014, when communications were lost following a planned reset of the spacecraft.

These detailed images of the Sun’s surface and atmosphere allow scientists to better track the formation of solar events. STEREO-A is also using this stronger signal to send high-definition views of the Sun’s far side with a two- to three-day delay. Now that STEREO-A has emerged from behind the Sun, scientists have once again pointed the main lobe of STEREO-A’s antenna towards Earth and the stronger signal means that the majority of the beacon data can once again be picked up. ![]() Since August 2014, our line of communication to the spacecraft was so close to the Sun that pointing the antenna straight at Earth also meant pointing it nearly directly at the Sun, which would cause the spacecraft’s antenna to dangerously overheat. Working to tackle these challenges and more is the Scalable Traffic Management for Emergency Response Operations project, or STEReO, led by NASAs Ames Research. “Having a second set of coronagraph images, in addition to those from the Solar and Heliospheric Observatory (SOHO), means we can measure coronal mass ejections much more accurately.”įor the past year, however, beacon data was only received for a few hours each day-if at all-limiting scientists’ ability to monitor the Sun. “STEREO-A’s real-time data is key for scientists to make accurate models of interplanetary space weather,” said Yari Collado-Vega, a space scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. ![]()
