New data from NASA’s SDO (Solar Dynamics Observatory) is available at its regular frequency following a data outage in November 2024. A small amount of historical data collected prior to 2014 is still being restored from backups. The SDO mission provides critical, near-real-time and high-resolution solar observations for the study of the near-Earth space environment …
Work on the NISAR satellite has been completed at the Indian Space Research Organisation (ISRO) Satellite Integration and Testing Establishment in Bengaluru, and preparations are under way to transport it to the launch site at the agency’s Satish Dhawan Space Centre in Sriharikota on India’s southeastern coast. NASA and ISRO now are reviewing potential launch …
NASA’s Lucy spacecraft is less than one month away from its next asteroid encounter. As it approaches, Lucy is keeping an eye on its target, the small main belt asteroid Donaldjohanson, using its high-resolution imager, L’LORRI, for optical navigation. At its closest point, Lucy will fly 600 miles (960 km) from Donaldjohanson, a distance carefully...
Since near-Earth asteroid 2024 YR4 was first discovered in December 2024, NASA and the worldwide planetary defense community have continued to observe the asteroid, which was ruled out as a significant impact risk to Earth. New infrared observations from NASA’s James Webb Space Telescope have decreased the uncertainty of the asteroid’s size and 2024 YR4...
Editor’s Note: This post highlights data from Webb science in progress, which has not yet been through the peer-review process. These results were reported as part of NASA’s role in the International Asteroid Warning Network. NASA’s James Webb Space Telescope recently turned its watchful eye toward asteroid 2024 YR4, which we now know poses no significant …
Work on NASA’s purpose-built asteroid hunter, Near-Earth Object (NEO) Surveyor, is progressing toward a targeted late 2027 launch. A major component of the mission, the spacecraft’s instrument enclosure journeyed back to the agency’s Jet Propulsion Laboratory in Southern California in early March after completing environmental testing at NASA’s Johnson Space Center in Houston. Built at …
The Sun emitted a strong solar flare, peaking at 11:21 a.m. ET on Friday, March 28. NASA’s Solar Dynamics Observatory, which watches the Sun constantly, captured an image of the event. Solar flares are powerful bursts of energy. Flares and solar eruptions can impact radio communications, electric power grids, navigation signals, and pose risks to …

NASA’s Parker Solar Probe completed its 23rd close approach to the Sun on March 22, equaling its own distance record by coming within about 3.8 million miles (6.1 million kilometers) of the solar surface. The close approach (known as perihelion) occurred at 22:42 UTC — or 6:42 p.m. EDT — with Parker Solar Probe moving …
At 3 p.m. EDT on Monday, March 24, hear from experts and ask your questions about NASA’s newly launched EZIE (Electrojet Zeeman Imaging Explorer) mission to investigate auroral electrojets, intense electrical currents that flow through our upper atmosphere in the polar regions where auroras glow in the sky. The EZIE trio of spacecraft launched March …
