GREENBELT, Md. (NASA PR) — NASA’s Solar Terrestrial Relations Observatory, or STEREO-A spacecraft, captured these images of comet ATLAS as it swooped by the Sun from May 25 – June 1. During the observations and outside STEREO’s field of view, ESA/NASA’s Solar Orbiter spacecraft crossed one of the comet’s two tails.

Tne failures of three aging satellites the United States relies upon to forecast space weather could leave the nation partially blind to electromagnetic storms that could severely disrupt electrical grids, communications systems, aviation and Global Positioning System (GPS) dependent navigation.

“The observations that we rely on to provide alerts and warnings are critical. Should we lose some of the key spacecraft that we talk about, I won’t say we’re blind but we’re darn close. It will impact our ability to support this nation’s need for space weather services. And I don’t want to see that happen,” said William Murtagh, director of NOAA’s Space Weather Prediction Center.

SWINDON, UK (UKSA PR) — Teams from across the UK will work on a concept for a future European mission to help reduce the global risk of damage caused by space weather.

Space weather occurs when the sun ejects material which can be highly charged, super heated and hazardous to manmade infrastructure and human life in space.
