New Evidence Adds to Findings Hinting at Network of Caves on Moon – NASA Science

New Evidence Adds to Findings Hinting at Network of Caves on Moon – NASA Science

Like “lava tubes” found here on Earth, scientists suspect that lunar caves formed when molten lava flowed beneath a field of cooled lava, or a crust formed over a river of lava, leaving a long, hollow tunnel. If the ceiling of a solidified lava tube collapses, it opens a pit, like a skylight, that can … Read more

Behind the Scenes of a NASA ‘Moonwalk’ in the Arizona Desert – NASA Science

Behind the Scenes of a NASA ‘Moonwalk’ in the Arizona Desert – NASA Science

During the Arizona moonwalks, scientists learned how to communicate their priorities succinctly and clearly to the flight control team, which then talked with the astronauts. If scientists needed to change the traverse plan to return to a site for more pictures, for instance, they had to rationalize the request to the flight director in charge. … Read more

NASA Selects Participating Scientists to Join ESA’s Hera Mission – NASA Science

NASA has selected 12 participating scientists to join ESA’s (European Space Agency) Hera mission, which is scheduled to launch in October 2024. Hera will study the binary asteroid system Didymos, including the moonlet Dimorphos, which was impacted by NASA’s DART (Double Asteroid Redirection Test) spacecraft on Sept. 26, 2022. The objectives of DART and Hera … Read more

NASA, Partners Conduct Fifth Asteroid Impact Exercise, Release Summary – NASA

For the benefit of all, NASA released a summary Thursday of the fifth biennial Planetary Defense Interagency Tabletop Exercise. NASA’s Planetary Defense Coordination Office, in partnership with FEMA (Federal Emergency Management Agency) and with the assistance of the U.S. Department of State Office of Space Affairs, convened the tabletop exercise to inform and assess our … Read more

NASA to Discuss Outcome of 5th Biennial Asteroid Threat Exercise – NASA

NASA to Discuss Outcome of 5th Biennial Asteroid Threat Exercise – NASA

NASA will host a virtual media briefing at 3:30 p.m. EDT, Thursday, June 20, to discuss a new summary of a recent tabletop exercise to simulate national and international responses to a hypothetical asteroid impact threat. The fifth biennial Planetary Defense Interagency Tabletop Exercise was held April 2 and 3, 2024, at the Johns Hopkins … Read more

Ongoing Venus Volcanic Activity Discovered With NASA’s Magellan Data – NASA

Ongoing Venus Volcanic Activity Discovered With NASA’s Magellan Data – NASA

An analysis of data from Magellan’s radar finds two volcanoes erupted in the early 1990s. This adds to the 2023 discovery of a different active volcano in Magellan data. Direct geological evidence of recent volcanic activity on Venus has been observed for a second time. Scientists in Italy analyzed archival data from NASA’s Magellan mission … Read more

NASA Recognizes 5 Early Career Planetary Scientists – NASA Science

NASA Recognizes 5 Early Career Planetary Scientists – NASA Science

Peter James, Baylor University in Waco, Texas: Dr. James’ project suite of research tasks, “Origins of porosity on rocky planetary surfaces,” will address the creation and evolution of porosity in the crusts of rocky planets. This project will also involve the development of a cratering workshop (“Crater Bootcamp”) with undergraduate students at the University of … Read more

Pushing the Limits of Sub-Kilowatt Electric Propulsion Technology to Enable Planetary Exploration and Commercial Mission Concepts – NASA Science

Pushing the Limits of Sub-Kilowatt Electric Propulsion Technology to Enable Planetary Exploration and Commercial Mission Concepts – NASA Science

Planetary science missions using small spacecraft will be required to perform challenging propulsive maneuvers—such as achieving planetary escape velocities, orbit capture, and more—that require a velocity change (delta-v) capability well in excess of typical commercial needs and the current state-of-the-art. Therefore, the #1 enabling technology for these small spacecraft missions is an electric propulsion system … Read more

Why is Methane Seeping on Mars? NASA Scientists Have New Ideas – NASA Science

Why is Methane Seeping on Mars? NASA Scientists Have New Ideas – NASA Science

Living creatures produce most of the methane on Earth. But scientists haven’t found convincing signs of current or ancient life on Mars, and thus didn’t expect to find methane there. Yet, the portable chemistry lab aboard Curiosity, known as SAM, or Sample Analysis at Mars, has continually sniffed out traces of the gas near the … Read more
