Elite Team to Consider New Approaches to Asteroid Danger

A six-week-long research accelerator, championed by NASA's Office of the Chief Technologist and hosted at the SETI Institute, is engaging young researchers from around the world to take on one of the truly existential threats to our species.

The NASA Frontier Development Lab (FDL) is bringing together a team of postgraduate researchers in data analytics and planetary science and challenging them to think outside the box on the threat of asteroid impacts. The initiative is under the aegis of experts from the space agency and the SETI Institute, with deep-learning expertise contributed by NVIDIA and Autodesk.

Asteroids that collide with Earth are one cosmic danger that it's now possible to mitigate. In 2013, NASA's Asteroid Grand Challenge charged participants with identifying all possible asteroid threats, and determining what to do about them.

FDL co-director, James Parr, describes the concept: "Grand challenges, such as detecting and characterizing the potentially hazardous asteroids we can't see, demand ingenious new applications of emerging technologies. With FDL, we aimed to create a platform combining emerging talent in machine learning and planetary science to find genuinely new methodologies for planetary defense."

To this end, young researchers from around the world have gathered at the SETI Institute to brainstorm such matters as

(1) new ways to visualize and characterize near-Earth objects (NEOs) considered to be potentially hazardous;

(2) the benefits of future space missions to both discover and image these objects;

(3) how we might better use radar to determine their size and shape, and

(4) the possibility of designing specialized drones able to speed the search for landed meteorite fragments that are difficult and time-consuming to find.

"We are delighted to be hosting the FDL research accelerator and providing mentor support in asteroid studies," notes Bill Diamond, SETI Institute CEO. "This program, involving top postdoctoral researchers in deep learning and planetary science, has the potential to deliver groundbreaking results, and serve as a model for demonstrating the power of public/private partnerships."

SETI Institute scientists specializing in asteroid and meteor research will be among the mentors for the Lab, as will other experts from NASA and industry.

These include the agency's Deputy Chief Technologist, Jim Adams and its Chief Systems Engineer for the Space Portal Office at NASA Ames, Bruce Pittman. Machine learning, a promising capability of today's advanced computing technology, is expected to be a key tool in addressing the asteroid challenge. Alison B. Lowndes of NVIDIA and Jonathan Knowles of Autodesk are consulting advisors to FDL.

"NVIDIA is allowing scientists to do their life's work," notes Lowndes, NVIDIA's Deep Learning Solutions Architect and Community Manager.

"Bringing together astrophysics, astrobiology and computer science is something I am immensely proud to do. It is a continuation of my mother's work at the European Space Research and Technology Center." NVIDIA specializes in visual computing, and produces graphics processing units that accelerate scientific computation and enable artificial intelligence techniques like deep learning.

Apollo astronaut and B612 co-founder Rusty Schweickart will address FDL participants during the workshop. He will be joined by space industry pioneers including Rick Tumlinson and Daniel Faber of Deep Space Industries, and Chris Lewicki, founder and CEO of Planetary Resources.

In addition to its utility in coming up with breakthroughs to aid asteroid defense, the FDL Grand Challenge project will provide a meaningful research experience for young scientists and demonstrate the potential of the Frontier Development Lab approach for generating significant new ideas of value to NASA's mission.
