NASA Seminars on Properties of Near Earth Asteroids

Status Report From: Solar System Exploration Research Virtual Institute (SSERVI)
Posted: Friday, February 7, 2014


NASA is sponsoring a series of virtual seminars on the properties of Near Earth Asteroids (NEAs) and what is being done to learn more about the hazards and the opportunities they may pose for us here on Earth. Each seminar will focus on some aspect of the asteroid population, how we discover and track NEAs, and what we need to know about them if we are ever required to change the orbit of a NEA that is an impact threat. The seminars will be held at 11am (Eastern) on the second and fourth Fridays of each month. 

The first 5 speakers are:

- Feb 14 Lindley Johnson (NASA Headquarters): NASA's NEA programs

- Feb 28 David Morrison (NASA Ames & SSERVI): History of impacts research and planetary defense

- Mar 14 Paul Chodas (NEO Program Office at JPL): NEA discovery, orbit calculation and impact probability

- Mar 28 Alan Harris (JPL retired): NEA populations and impact frequency

- Apr 11 Dan Britt (University of Central Florida): Physical properties of NEAs

This seminar series is sponsored by The NASA Asteroid Grand Challenge Office, with the NASA Near Earth Object Observations Program and the NASA Solar System Exploration Research Virtual Institute (SSERVI). More information is available at:
