Before departing for Earth on May 10, the OSIRIS-REx spacecraft will perform a final flyby of Bennu – capturing its last images of sample collection site Nightingale.
On May 10, the OSIRIS-REx spacecraft will depart asteroid Bennu and begin its two-year journey back to Earth, where scientists will study the dust and rocks it collected from the asteroid's surface.
Planetary scientists wondered if bands of winds or swirling storms dominated the atmospheres of brown dwarfs. UArizona-led research solved the mystery.
Mars once had oceans but is now bone-dry, leaving many to wonder how the water was lost. New research suggests that the water escaped not like a leaky faucet, but with a sudden splash.
The OSIRIS-REx spacecraft successfully collected a large sample from the asteroid Bennu. But because some large pieces of rock are keeping the sample head from fully closing, the team has decided to expedite the stowing process.
Elisabeth Krause has been selected for a Packard Fellowship for Science and Engineering. The $875,000 award will allow her to expand her research on the structure of the universe.
The UArizona-led OSIRIS-REx mission will attempt to collect a sample from asteroid Bennu on Oct. 20. Before the spacecraft touches the surface, scientists are learning more about the material that makes up the asteroid.
The gravitational push and pull by Jupiter's moons could account for more warming than the gas giant Jupiter alone, through a process called tidal heating.
The NEOWISE mission, led by UArizona's Amy Mainzer, discovered comet C/2020 F3 NEOWISE in March. The comet is now making its way around the sun and is visible from Earth.
Analysis of data from NASA's Cassini spacecraft found a viable explanation for what keeps the upper layers of Saturn so hot: auroras at the planet's north and south poles.
