The House Science Committee approved an infrastructure bill that provides an additional $173 million to the National Oceanic and Atmospheric Administration (NOAA) to accelerate the development and launch of the Space Weather Follow-On Lagrange-1 (SWFO-L1) mission. The spacecraft, scheduled for launch in 2024, will monitor the solar wind and coronal mass ejections from the Earth-sun L-1 Lagrange point.
ASHINGTON (NASA PR) — NASA has approved two heliophysics missions to explore the Sun and the system that drives space weather near Earth. Together, NASA’s contribution to the Extreme Ultraviolet High-Throughput Spectroscopic Telescope Epsilon Mission, or EUVST, and the Electrojet Zeeman Imaging Explorer, or EZIE, will help us understand the Sun and Earth as an interconnected system.
A bill to reorganize the nation’s response to space weather has passed both houses of Congress and heads to the White House for President Donald Trump’s signature.
The Promoting Research and Observations of Space Weather to Improve the Forecasting of Tomorrow Act (PROSwift) assigns roles to federal departments and establishes an interagency working group to coordinate their activities.
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) — The Sun is Earth’s nearest star—a giant orb of hydrogen and helium about 93 million miles away. To many people, it looks like the same constant ball of light day after day as it moves across the sky. However, our Sun actually goes through a cycle of increasing and decreasing activity that lasts for about 11 years.
MOSCOW (Skoltech PR) — Scientists at Skolkovo Institute of Science and Technology (Skoltech), together with colleagues from the Karl-Franzens University of Graz the the Kanzelhöhe Observatory (Austria), Jet Propulsion Laboratory of California Institute of Technology (USA), Helioresearch (USA) and Space Research Institute of the Russian Academy of Sciences (Russia) developed a method to study fast Coronal Mass Ejections, powerful ejections of magnetized matter from the outer atmosphere of the Sun.
The results can help to better understand and predict the most extreme space weather events and their potential to cause strong geomagnetic storms that directly affect the operation of engineering systems in space and on Earth. The results of the study are published in the Astrophysical Journal.
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.
