Like boulders, rocks, and pebbles scattered across a landscape, asteroids come in a wide range of sizes. Cataloging asteroids in space is tricky because they are faint and they don’t stop to be photographed as they zip along their orbits around the Sun. Astronomers recently used a trove of archived images taken by NASA’s Hubble […]
NASA’s TESS (Transiting Exoplanet Survey Satellite) has returned to work after science observations were suspended on April 8, when the spacecraft entered into safe mode. All instruments are powered on and, following the successful download of previously collected science data stored in the mission’s recorder, are now making new science observations. Analysis of what triggered […]
The PACE (Plankton, Aerosol, Cloud, ocean Ecosystem) mission has delivered its first operational data back to researchers, a feat made possible in part by innovative, data-storing technology from NASA’s Near Space Network, which introduced two key enhancements for PACE and other upcoming science missions. As a satellite orbits in space, its systems generate critical data […]
In anticipation of Earth Day, NASA invites media to a briefing at the agency’s headquarters on Friday, April 19, at 11 a.m. EDT. The event will share updates on NASA’s climate science and early data from the agency’s ocean-watching PACE (Plankton, Aerosol, Cloud, ocean Ecosystem) mission, as well as reveal upcoming Earth airborne missions. The […]
Natural disasters like volcanic eruptions, floods, and tornados can dramatically change the surface of Earth to the point where alterations are visible in space. Changes driven by human actions and interventions, such as mining and deforestation, are also visible in satellite imagery. For over 50 years, NASA’s Landsat satellites have recorded our planet’s changing surface. […]
NASA is planning to repair NICER (Neutron star Interior Composition Explorer), an X-ray telescope on the International Space Station, during a spacewalk later this year. It will be the fourth science observatory in orbit serviced by astronauts. In May 2023, scientists discovered that NICER had developed a “light leak.” Unwanted sunlight was entering the instrument […]
Engineers at L3Harris Technologies in Rochester, New York, have combined all 10 mirrors for NASA’s Nancy Grace Roman Space Telescope. Preliminary tests show the newly aligned optics, collectively called the IOA (Imaging Optics Assembly), will direct light into Roman’s science instruments extremely precisely. This will yield crisp images of space once the observatory launches. “This […]
NASA has confirmed its Dragonfly rotorcraft mission to Saturn’s organic-rich moon Titan. The decision allows the mission to progress to completion of final design, followed by the construction and testing of the entire spacecraft and science instruments. “Dragonfly is a spectacular science mission with broad community interest, and we are excited to take the next […]
Did you know the Sun has moss? Due to its resemblance to the earthly plants, scientists have named a small-scale, bright, patchy structure made of plasma in the solar atmosphere “moss.” This moss, which was first identified in 1999 by NASA’s TRACE mission, blossoms around the center of a sunspot group, where magnetic conditions are […]
