NASA’s Juno mission has provided the first measurements of the temperature below the surface of Jupiter’s moon Io, revealing significant heating within the shallow subsurface of the most volcanically active world in the solar system. Collected during two close flybys, the data also shows that most of Io’s surface is remarkably smooth and composed of […]
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 […]
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 […]
July 8, 2026 C.13 NASA Awards Contracts for Mars Advanced Surface Mobility Technology NASA has selected seven companies for contract awards under the Mars Exploration Program’s Science Transport and Robotic Innovation for Deployment and Exploration, or STRIDE, initiative to advance next-generation commercial robotic surface mobility for future Mars exploration. The STRIDE awards will support the […]
NASA has revealed two new “super-puff” planets, giant worlds so light that their density is comparable to cotton candy. Scientists calculate that these Jupiter-sized planets are the “puffiest” worlds ever found.
Even small asteroids lead complex lives. During its flyby of the asteroid Donaldjohanson last year, NASA’s Lucy spacecraft revealed the asteroid to be a wobbly, peanut-shaped body that has undergone a lot of activity in its relatively short history. Formed as fragments coalesced after a violent collision 155 million years ago, the asteroid was transformed by the […]
As NASA’s Artemis II astronauts zipped around the Moon in early April, they observed flashes of light caused by meteoroids hitting the lunar surface. At the same time, volunteers for the NASA-funded Impact Flash project scanned the Moon with their own telescopes and sent their videos to scientists to share what they saw from Earth.
Astronomers using NASA’s Hubble Space Telescope have found evidence that the spinning of a small comet slowed and then reversed its direction of rotation, offering a dramatic example of how volatile activity can affect the spin and physical evolution of small bodies in the solar system. This is the first time researchers have observed evidence […]
This letter from SARA is to issue a waiver for NASA grantees attending LPSC2026, allowing them to be reimbursed out of their grants for their actual lodging, although it’s expected to be above the approved GSA amount. This waiver does not supersede the travel policy of your institution if it is more restrictive. Note: I have […]
NASA is getting ready to send four astronauts around the Moon with Artemis II, laying the foundation for sustainable missions to the lunar surface and paving the way for human exploration on Mars. As the agency considers deep space endeavors that could last months or years, it must develop ways to feed astronauts beyond sending […]
