NASA’s SPHEREx space telescope is beginning to look much like it will when it arrives in Earth orbit and starts mapping the entire sky. Short for Specto-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer, SPHEREx resembles a bullhorn, albeit one that will stand almost 8.5 feet tall (2.6 meters) and stretch nearly 10.5 feet (3.2 meters) wide. Giving the…
An analysis by NASA’s sea level change science team finds that if a strong El Niño develops this winter, cities along the western coasts of the Americas could see an increase in the frequency of high-tide flooding that can swamp roads and spill into low-lying…
The Euclid mission, which will investigate the mysteries of dark matter and dark energy, released its first five science images Tuesday, Nov. 7 The observatory, led by ESA (European Space Agency) with NASA contributions, is scheduled to begin regular science operations in…
NASA’s Curiosity Rover Clocks 4,000 Days on Mars
November 7, 2023
Four thousand Martian days after setting its wheels in Gale Crater on Aug. 5, 2012, NASA’s Curiosity rover remains busy conducting exciting science. The rover recently drilled its 39th sample then dropped the pulverized rock into its belly for detailed analysis.
To study whether ancient Mars had the conditions to support microbial life, the rover has been gradually ascending the base of…
When mechanical engineers accustomed to building one-of-a-kind spacecraft turn that focus to pumpkins, the results can be hauntingly good. The annual Halloween pumpkin-carving contest at NASA’s Jet Propulsion Laboratory in Southern California may be all in good fun, but to…
In Alaska’s largest river delta, tundra that has been scorched by wildfire is emitting more methane than the rest of the landscape long after the flames died, scientists have found. The potent greenhouse gas can originate from decomposing carbon stored in permafrost for…
Salts and Organics Observed on Ganymede’s Surface by NASA’s Juno
November 2, 2023
NASA’s Juno mission has observed mineral salts and organic compounds on the surface of Jupiter’s moon Ganymede. Data for this discovery was collected by the Jovian InfraRed Auroral Mapper (JIRAM) spectrometer aboard the spacecraft during a close flyby of the icy moon. The findings, which could help scientists better understand the origin of Ganymede and the composition of its deep ocean, were…
NASA’s Lucy mission will soon have its first asteroid encounter as the spacecraft travels through deep space en route to Jupiter’s orbit. But before the spacecraft passes 265 miles (425 kilometers) from the surface of the small asteroid Dinkinesh, researchers have used…
See SWOT Mission’s Unprecedented View of Global Sea Levels
November 2, 2023
The Surface Water and Ocean Topography (SWOT) satellite is sending down tantalizing views of Earth’s water, including a global composite of sea surface heights. The satellite collected the data visualized above during SWOT’s first full 21-day science orbit, which it…
The Crab Nebula Seen in New Light by NASA’s Webb
October 30, 2023
NASA’s James Webb Space Telescope has gazed at the Crab Nebula, a supernova remnant located 6,500 light-years away in the constellation Taurus. Since the recording of this energetic event in 1054 C.E. by 11th-century astronomers, the Crab Nebula has continued to draw attention and additional study as scientists seek to understand the conditions, behavior, and after-effects of supernovae through…
