5 Surprising NASA Heliophysics Discoveries Not Related to the Sun

With NASA’s fleet of heliophysics spacecraft, scientists monitor our Sun and investigate its influences throughout the solar system. However, the fleet’s constant watch and often-unique perspectives sometimes create opportunities to make discoveries that no one expected, helping us to solve mysteries about of the solar system and beyond.

Hurricane Helene’s Gravity Waves Revealed by NASA’s AWE

On Sept. 26, 2024, Hurricane Helene slammed into the Gulf Coast of Florida, inducing storm surges and widespread impacts on communities in its path. At the same time, NASA’s Atmospheric Waves Experiment, or AWE, recorded enormous swells in the atmosphere that the hurricane produced roughly 55 miles above the ground.

Final Venus Flyby for NASA’s Parker Solar Probe Queues Closest Sun Pass

On Wednesday, Nov. 6, 2024, NASA’s Parker Solar Probe will complete its final Venus gravity assist maneuver, passing within 233 miles (376 km) of Venus’ surface. The flyby will adjust Parker’s trajectory into its final orbital configuration, bringing the spacecraft to within an unprecedented 3.86 million miles of the solar surface on Dec.

30 Years On, NASA’s Wind Is a Windfall for Studying our Neighborhood in Space

Picture it: 1994. The first World Wide Web conference took place in Geneva, the first Chunnel train traveled under the English Channel, and just three years after the end of the Cold War, the first Russian instrument on a U.S. spacecraft launched into deep space from Cape Canaveral. The mission to study the solar wind, […]

NASA to Launch Innovative Solar Coronagraph to Space Station

NASA’s Coronal Diagnostic Experiment (CODEX) is ready to launch to the International Space Station to reveal new details about the solar wind including its origin and its evolution. Launching in November 2024 aboard SpaceX’s 31st commercial resupply services mission, CODEX will be robotically installed on the exterior of the space station.

Voyager 1 Team Accomplishes Tricky Thruster Swap

The spacecraft uses its thrusters to stay pointed at Earth, but after 47 years in space some of the fuel tubes have become clogged. Engineers working on NASA’s Voyager 1 probe have successfully mitigated an issue with the spacecraft’s thrusters, which keep the distant explorer pointed at Earth so that it can receive commands, send […]

NASA, ESA Missions Help Scientists Uncover How Solar Wind Gets Energy

Since the 1960s, astronomers have wondered how the Sun’s supersonic “solar wind,” a stream of energetic particles that flows out into the solar system, continues to receive energy once it leaves the Sun. Now, thanks to a lucky lineup of a NASA and an ESA (European Space Agency)/NASA spacecraft both currently studying the Sun, they […]

NASA’s ICON Mission Ends with Several Ionospheric Breakthroughs

After contributing to many important findings on the boundary between Earth’s atmosphere and space — an area where space weather can interfere with both satellites and communications signals — NASA’s ICON (Ionospheric Connection Explorer) mission has come to an end.

Alphabet Soup: NASA’s GOLD Finds Surprising C, X Shapes in Atmosphere

Who knew Earth’s upper atmosphere was like alphabet soup? NASA’s Global-scale Observations of the Limb and Disk (GOLD) mission has revealed unexpected C- and X-shaped formations in an electrified layer of gas high above our heads called the ionosphere.
