An intensifying research focus on asteroids reveals two main points: There are a lot of them, and we don’t know a lot about them.
What can be said is that in the quest to learn more about asteroid shapes, Northern Arizona University is a world apart. In fact, NAU is the number one producer of newly calculated asteroid shapes on the planet.
“Although more than 700,000 asteroids are known to us as of today, we still know very little about these… Read more
A team led by David Trilling, associate professor of astronomy at Northern Arizona University, has been selected to receive a NASA Group Achievement Award.
According to NASA, the Spitzer Near Earth Asteroid Team is being recognized “for exemplary science implementation, analysis and execution of the Spitzer 2011 MD and 2009 BD near-Earth Asteroid Observations for NASA’s Asteroid Redirect Mission.” Trilling, NAU post-doctoral researcher Michael Mommert and colleagues from four other institutions participated in the research.
The award will be presented… Read more
For eons, ancient objects have slipped stealthily past Earth, their anonymity assured in the vastness of space. But now the clumps, chunks and misshapen islands of rock are being observed and measured within hours of their discovery, thanks to ingenuity, technology and the curiosity of David Trilling.
The rapid generation of data from asteroids is just one item in the field of view of the Northern Arizona University astronomer and his close collaborator, post-doctoral researcher Michael Mommert.
What seemed to be rock-solid assumptions about the nature of small asteroids may end in collections of rubble or even a cloud of dust, but in such findings lies the lure of the unexpected.
Northern Arizona University researchers David Trilling and Michael Mommert, while playing a well-defined role in the NASA Asteroid Initiative, are beginning to wonder if they have found a separate path of investigation.
The two researchers presented their findings about asteroid 2011 MD on Thursday during a… Read more

We could study an asteroid up close by sending astronauts to one somewhere out in space—or we could simply bring one to the astronauts.
That’s basically the idea behind NASA’s announced Asteroid Robotic Retrieval Mission, which aims to catch a near-Earth asteroid and redirect it in an orbit around the moon. There, the asteroid could be visited and scrutinized by astronauts.
Surprisingly, the biggest problem with this idea is… Read more
For 30 years, a large near-Earth asteroid wandered its lone, intrepid path, passing before the scrutinizing eyes of scientists while keeping something to itself: 3552 Don Quixote, whose journey stretches to the orbit of Jupiter, now appears… Read more
