SILVER SPRING, Md. (NOAA PR) — Over the course of the Sun’s 11-year solar cycle, the star goes through a period of increased and decreased activity. When this activity ramps up, sometimes phenomena such as solar flares and coronal mass ejections (CMEs), where massive amounts of radiation and solar particles erupt out from the Sun’s surface, can wreak havoc if our planet happens to be in the way of the blast.
SILVER SPRING, Md. (NOAA PR) — As an agency, NOAA’s science isn’t just limited to Earth and its atmosphere. NOAA’s reach goes from the surface of the Sun to the depths of the ocean floor as we work to keep the public informed of the changing environment around them. So, what sort of instruments help scientists detect what’s going on in the Sun in the first place?
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.
