Highly Porous Rocks Responsible for Bennu's Surprisingly Craggy Surface
Using data from NASA OSIRIS-REx mission, a University of Arizona-led team of scientists concluded that asteroids with highly porous rocks, such as Bennu, should lack fine-grained material on their surfaces.
'Mini Psyches' Give Insights into Mysterious Metal-Rich Near-Earth Asteroids
New research into metal-rich asteroids reveals information about the origins and compositions of these rare bodies that could one day be mined.
Earth and Venus Grew up as Rambunctious Planets
What doesn't stick comes around: Using machine learning and simulations of giant impacts, researchers at the Lunar and Planetary Laboratory found that the planets residing in the inner solar systems were likely born from repeated hit-and-run collisions, challenging conventional models of planet formation.
Dr. Heather Knutson Named Showman Distinguished Visiting Lecturer
Professor Heather Knutson has been named the inaugural speaker for the Adam P. Showman Distinguished Visiting Lectureship , scheduled for April 18-22, 2022.
OSIRIS-REx Improves Understanding of Potentially Hazardous Asteroids
NASA and UArizona scientists were able to significantly reduce uncertainties about asteroid Bennu's orbit and determine the likelihood of the asteroid impacting Earth between now and the year 2300.
Mars Lake Hypothesis on Ice After Study Offers Different Explanation
Scientists have long debated what's under the surface of Mars' south pole. A new study points to clays being more likely than a subsurface lake. https://www.lpl.arizona.edu/postdocs/stefano-nerozzi
NASA Extends UArizona-Led Asteroid Search Mission
For two more years, NASA's Near-Earth Object Wide-field Infrared Survey Explorer, or NEOWISE, will continue its hunt for asteroids and comets – including objects that could pose a hazard to Earth.
Researchers Trace Dust Grain's Journey Through Newborn Solar System
Combining atomic-scale sample analysis and models simulating likely conditions in the nascent solar system, a new study reveals clues about the origin of crystals that formed more than 4.5 billion years ago.
UArizona to Lead Mission to Discover Potentially Dangerous Asteroids
NASA has tasked Amy Mainzer, an expert in infrared astronomy at the University of Arizona, with delivering NEO Surveyor, a mission to find, track and characterize yet unseen asteroids and comets that may pose a threat to Earth.
Asteroid 16 Psyche Might Not Be What Scientists Expected
New UArizona research finds that the target asteroid of NASA's Psyche mission may not be as metallic or dense as previously predicted.
