As Chinese space station Tiangong-1 falls to Earth, UA astronomer Vishnu Reddy and aerospace engineering graduate student Tanner Campbell are following its path using technology they developed in four months — and with less than $2,000.

RADARMET is led by Vishnu Reddy, assistant professor in the University of Arizona's Lunar and Planetary Laboratory. He procured funding from NASA to operate RADARMET, which uses National Weather Service Doppler radar data and computer models to locate meteorites within hours of their fall.

Students were part of a drill that tested astronomers' ability to respond to a highly unlikely — but not impossible — scenario: an asteroid on course to collide with Earth.

Congratulations to Allison McGraw, 2016 UA Space Grant Intern and May graduate, for receiving a Lloyd V. Berkner Space Policy Graduate Internship award with the Space Studies Board at The National Academies of Sciences, Engineering and Medicine in Washington, D.C. for the fall 2017 season. 

At the 49th Annual Division for Planetary Sciences Meeting in Provo, Utah, astronomers led by Vishnu Reddy at the University of Arizona confirm true nature of one of Earth's companions on its journey around the sun.

Undergraduate Adriana Mitchell already has her sights set on worlds far across the solar system. But right now, thanks to a virtual telescope stretching across 2,500 miles, she is poised to find answers to questions about the sun that have eluded scientists for decades.

Professor Vishnu Reddy of the University of Arizona's Lunar and Planetary Laboratory in Tucson leads the campaign to reacquire 2012 TC4 and sees it as an opportunity for the collaborative observation campaign to utilize the international aspect of the network.
