Just like we experience weather on Earth, there’s weather in space! The Sun may look very constant and quiet from Earth, but it’s constantly spewing out a stream of particles called the solar wind. Space weather is activity on the Sun that can affect Earth and interact with our technology.

LAUREL, Md. — NASA’s Parker Solar Probe captured stunning views of Venus during its close flyby of the planet in July 2020.
Though Parker Solar Probe’s focus is the Sun, Venus plays a critical role in the mission: The spacecraft whips by Venus a total of seven times over the course of its seven-year mission, using the planet’s gravity to bend the spacecraft’s orbit. These Venus gravity assists allow Parker Solar Probe to fly closer and closer to the Sun on its mission to study the dynamics of the solar wind close to its source.
SILVER SPRING, Md. (NOAA PR) — NOAA has awarded the Space Weather Follow On-Lagrange 1 (SWFO-L1) Command and Control contract to L3Harris in Melbourne, Florida. The cost plus fixed-fee contract has a total value of $43,784,063, with a five-year performance period. The SWFO-L1 mission is planned to launch in 2025 as a ride share with the NASA Interstellar Mapping and Acceleration Probe.
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.
WASHINGTON (NASA PR) — In 2020, NASA made significant progress on America’s Moon to Mars exploration strategy, met mission objectives for the Artemis program, achieved significant scientific advancements to benefit humanity, and returned human spaceflight capabilities to the United States, all while agency teams acted quickly to assist the national COVID-19 response.

GREENBELT, Md. — At the edge of space, the ever-growing fleet of satellites in low-Earth orbit are locked in a constant, precarious battle with friction.
These satellites orbit in a normally quiet region hundreds of miles above the surface, at the edge of Earth’s atmosphere. Usually, the satellites only feel a gentle push due to the headwinds of the rarified air there, but extreme storms from the Sun can change Earth’s atmosphere enough to pull a satellite farther off orbit in one day than they’d normally experience in a year.
Washington, D.C. (Cory Gardner/Gary Peters PR) – U.S. Senators Cory Gardner (R-CO) and Gary Peters (D-MI) today applauded the signing into law of their bipartisan legislation to strengthen the nation’s ability to predict severe space weather events and mitigate their harmful impacts on Earth. A severe space weather event, such as a solar flare or coronal mass ejection, has the potential to seriously disrupt the electric power grid, communications networks including cellular phones and GPS, satellites, and aircraft operations.
President Donald Trump has signed a bill to reorganize and strengthen the nation’s monitoring of and response to space weather, albeit with some reservations about its impact on foreign policy and national security.
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.
KENNEDY SPACE CENTER, Fla. (NASA PR) — NASA has selected Space Exploration Technologies (SpaceX) of Hawthorne, California, to provide launch services for the agency’s Interstellar Mapping and Acceleration Probe (IMAP) mission, which includes four secondary payloads.
IMAP will help researchers better understand the boundary of the heliosphere, a magnetic barrier surrounding our solar system. This region is where the constant flow of particles from our Sun, called the solar wind, collides with winds from other stars. This collision limits the amount of harmful cosmic radiation entering the heliosphere.
SILVER SPRING, Md. (NOAA PR) — NOAA is planning an advanced satellite that will improve forecasts and warnings for potentially damaging solar activity while perched in a Sun-facing orbit a million miles from Earth.
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?
WASHINGTON (NASA PR) — Solar Cycle 25 has begun. During a media event on Tuesday, experts from NASA and the National Oceanic and Atmospheric Administration (NOAA) discussed their analysis and predictions about the new solar cycle – and how the coming upswing in space weather will impact our lives and technology on Earth, as well as astronauts in space.
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.
WASHINGTON (NASA PR) — NASA has selected five proposals for concept studies of missions to help improve understanding of the dynamics of the Sun and the constantly changing space environment with which it interacts around Earth. The information will improve understanding about the universe as well as offer key information to help protect astronauts, satellites, and communications signals – such as GPS – in space.
