UA Students Participate in First Global Planetary Defense Exercise

By Emily Walla, NASA Space Grant Intern, University Communications - December 4, 2017 University of Arizona students recently took part
This 2011 view near the top of the southern rim of Tivat Crater comes from the HiRISE camera on NASA's Mars Reconnaissance Orbiter. It shows the inner slope of a crater on southern Mars with several of the seasonal dark streaks called "recurrent slope lineae," or RSL. A November report interprets those as granular flows, rather than darkening due to flowing water. (Image: NASA/JPL-Caltech/UA/USGS)

Recurring Martian Streaks: Flowing Sand, Not Water?

Jet Propulsion Laboratory/Caltech and University Communications - Nov. 21, 2017 Dark features on Mars previously considered evidence for subsurface flowing

On Sept. 22, at a distance of 105,600 miles, the OSIRIS-REx MapCam captured this color image of Earth. Dark "icicles" at the top of the image were caused by short exposure time.

Earth to OSIRIS-REx Cameras: I'm Ready for My Close-Up

University Communications - October 4, 2017 On Sept. 22, OSIRIS-REx soared under the South Pole, coming within 10,600 miles of
This artist’s impression shows the binary asteroid 288P, located in the main asteroid belt between the planets Mars and Jupiter. The object is unique as it is a binary asteroid that also behaves like a comet. The cometlike properties are the result of water sublimation, caused by the heat of the sun. The orbit of the asteroids is marked by a blue ellipse. (Image: ESA/Hubble, L. Calçada)

Asteroid-Comet Is New Type of Object

OSIRIS-REx is scheduled to arrive at Bennu, a primitive carbonaceous asteroid, in the fall of 2018. After surveying Bennu for two years, the spacecraft will extend its sampling arm to touch down on the asteroid's surface and collect a sample of pristine asteroid material.

This artist's concept shows a brown dwarf with bands of clouds, thought to resemble those seen on Neptune and the other outer planets in the solar system. By using NASA's Spitzer Space Telescope, astronomers have found that the varying glow of brown dwarfs over time can be explained by bands of patchy clouds rotating at different speeds.
