NASA scientists last week removed the two stuck fasteners on the sample container that had prevented researchers from accessing much of OSIRIS-REx's asteroid Bennu sample.

Under the leadership of the University of Arizona's Dani Mendoza DellaGiustina, the former OSIRIS-REx spacecraft sets off on a journey to study asteroid Apophis and take advantage of the asteroid's 2029 flyby of Earth.

At the university's Kuiper-Arizona Laboratory for Astromaterials Analysis, a suite of instruments allows researchers to study the particles collected by the OSIRIS-REx mission the down to the atomic scale.

From delivering a historic asteroid sample to setting a university record in Fulbright Scholars, the University of Arizona celebrated several newsmaking events in 2023.

The findings from the University of Arizona-led study have implications for research into whether Mars could have harbored life at some point in its history.

Members of the public helped the University of Arizona's Catalina Sky Survey spot a previously unknown near-Earth asteroid on its orbit around the sun.

For the fifth consecutive year, the university is ranked among the nation's top 20 public research universities, according to the National Science Foundation.

The discovery of phosphorus in a molecular cloud at the edge of the Milky Way galaxy extends the presence of the element almost twice as far out as where it was known to exist.

A University of Arizona team tracked down a contested piece of space junk that crashed onto the moon. Their findings shed light on why it left not one but two craters.

NASA extended the University of Arizona-led OSIRIS-REx mission, which has since been renamed OSIRIS-APEX. The spacecraft will study another potentially hazardous, near-Earth asteroid named Apophis.
