Curious about the NASA Asteroid Grand Challenge to “discover all asteroids that could threaten human populations and find out how to deal with them”? 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. The purpose is to inform interested astronomers (both amateur and professional), students, teachers, and others who are potentially interested in contributing to studies of NEAs. 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 seminar format will be a 40-minute talk by an asteroid expert followed by 20 minutes for questions from the audience. They will be broadcast over the Internet. The audience will watch, listen and post questions by Adobe Connect using an Internet connection and a web browser.
The seminars will be held on the second and fourth Fridays of each month beginning on February 14. The time is 11:00 am Eastern, which will allow live audience participation over most of the United States, Europe, and Africa.
The schedule for the first five seminars is as follows:
- Feb 28 Lindley Johnson (NASA Headquarters):
NASA’s NEA programs
- Mar 14 Paul Chodas (NEO Program Office at JPL):
NEA discovery, orbit calculation and impact probability assessment
- Mar 28 Alan Harris (JPL retired):
NEA populations and impact frequency
- Apr 11 Dan Britt (University of Central Florida):
Physical properties of NEAs
If there is sufficient interest, the virtual seminar series will continue with talks on asteroid deflection strategies, the new International Warning Network, characterizing hazardous asteroids, radar studies of NEA orbits and surfaces, and finding destinations for robotic and human missions to asteroids.
This virtual seminar series is sponsored by the NASA Asteroid Grand Challenge (AGC) Office, in collaboration with the NASA Near Earth Object Observations (NEOO) Program and the NASA Solar System Exploration Research Virtual Institute (SSERVI).
