MarsNASA’s Curiosity Mars Rover Discovers Field of Honeycomb Textures
As NASA’s Curiosity rover recently began climbing up a Martian valley nicknamed “Valle Grande,” it sent back images that were a familiar sight to mission scientists: honeycomb-like textures called polygonal fractures, each one about 1.5 to 3 inches (4 to 8 centimeters) across. The mission has spotted small patches of these geometric shapes several times …
ISSNASA Astronaut Chris Williams Closes Out Space Station Mission
After eight months aboard the International Space Station for his first mission, NASA astronaut Chris Williams is preparing to return to Earth. During his assignment, Williams contributed to research for new cancer treatments, advanced the production of materials to improve computers and electronics, ventured into the vacuum of space to complete two spacewalks, and much …
EarthUS-India Satellite Delivers Data, Reveals ‘Hummingbird’ in Antarctica
As of July 20, the public can access data from the two powerful radar instruments aboard the NISAR (NASA-ISRO Synthetic Aperture Radar) satellite. Teams in the United States and India will release files processed from the satellite’s L-band and S-band radars on an ongoing basis, helping researchers and other users track the movement of Earth’s …
MarsEstablishing Crew Exposure Limits of Martian Dust
Background Human exploration of Mars will expose crews to a persistent, fine particulate environment whose physicochemical properties and health implications remain only partly understood. Because no samples of authentic Martian airborne dust have been returned to Earth, NASA must rely on lunar dust toxicology, Martian regolith simulants, and extensive rover/lander geochemical and mineralogical datasets to …
ArtemisNASA Welcomes Mauritius as 70th Artemis Accords Signatory
The Republic of Mauritius has officially joined the global coalition committed to responsible space exploration, becoming the newest signatory and seventh African country to join the Artemis Accords. NASA’s Deputy Administrator Matt Anderson contributed video remarks for a signing ceremony on Friday, in the island nation’s city of Ébène. “We are honored to welcome Mauritius …
ArtemisNASA Welcomes Serbia as Newest Artemis Accords Signatory
The Republic of Serbia signed the Artemis Accords Thursday during a ceremony hosted by NASA at the agency’s Headquarters in Washington, becoming the 69th nation to join a large community of like-minded nations committed to the peaceful, transparent, and responsible exploration of space. “Serbia’s connection to NASA reaches back to the Apollo program, when the …
AsteroidsNASA Study Finds Near-Earth Asteroid Is Actually Comet
New research led by scientists at NASA’s Jet Propulsion Laboratory in Southern California has revealed the identity of a puzzling near-Earth object by precisely tracking its motion through space and using powerful observatories that image faint celestial objects. This object has a dual personality: Past images hadn’t revealed obvious cometlike activity, suggesting it might be …
ArtemisHow NASA’s Artemis III Lander Test Will Pave Way for Moon Landings
Before Artemis astronauts land on the Moon’s surface in 2028, NASA will conduct the Artemis III demonstration mission in 2027, allowing teams on Earth and in orbit to practice rendezvous and docking operations between commercial human landing systems and the Orion spacecraft. Data from that mission, along with future uncrewed demonstration missions at the Moon, …
MarsNASA’s Perseverance Rover Reads Record of Ancient Mars Impacts
NASA’s Perseverance Mars rover has uncovered evidence that a 245-foot-thick (75-meter-thick) stack of ancient rock on the rim of Jezero Crater was built by repeated asteroid impacts. Referred to as the “Broom Point member” by the rover’s science team, this sequence of layered bedrock is likely more than 3.9 billion years old, making it among …
