Fernanda Henderikx-Freitas, assistant professor at University of Hawaii, is the lead principal investigator of the PACE validation team called the Hawaii Ocean Time-series program for validation of the PACE Mission in oligotrophic waters (HOT-PACE). The group is one of many in a campaign set out to gather data around the world to check the accuracy …
The Sun emitted a strong solar flare, peaking at 11:27 a.m. ET on Aug. 5, 2024. 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 …
The Sun emitted a strong solar flare, peaking at 9:40 a.m. ET on Aug. 5, 2024. 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 work on the radar antenna reflector for the NISAR (NASA-ISRO Synthetic Aperture Radar) satellite is nearing completion in California, with testing under way to verify that this hardware component will deploy properly following launch. Drum-shaped and about 39 feet (12 meters) across, the reflector is among NASA’s contributions to this joint mission with the …
The Sun emitted a strong solar flare, peaking at 10:37 p.m. on July 28, 2024. 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 spacecraft …

Launch preparations are progressing with NASA’s Europa Clipper mission. The spacecraft arrived at the agency’s Kennedy Space Center in Florida in May, where the team recently attached the high-gain antenna. Engineers with NASA’s Europa Clipper mission continue to conduct extensive testing of transistors that help control the flow of electricity on the spacecraft. NASA’s Jet …
NASA’s Parker Solar Probe completed its 20th close approach to the Sun on June 30, 2024.
NASA’s ICESat-2 satellite returned to science mode on June 21 UTC, after solar storms in May caused its height-measuring instrument to go into a safe hold. The ICESat-2 team restarted the mission’s instrument, a lidar called the Advanced Topographic Laser Altimeter System (ATLAS), which is once again collecting precise data on the height of Earth’s …
