Senate Space Roundtable on Asteroid Close Calls

Topic: Near Earth Asteroid Threat

Date: Wednesday, July 10, 2002

Location: Room 192 Dirksen Senate Office Building, Washington, DC, US, 20510

ProSpace, in conjunction with Space Frontier Foundation, is pleased to announce the ninth in our series of Space Roundtables at the United States Senate. Titled "The Asteroid Threat: Identification and Mitigation Strategies", this program will explore a range of ideas and information regarding the asteroids and other objects that cross the earth's orbit, what we are doing to find and track them and what we could be doing to protect the earth from a devastating impact.

The program will be held on Wednesday, July 10th at 1:00pm in room 192 of the Dirksen Senate Office Building. To attend, please RSVP to: Include your name, affiliation and telephone number.

You may be aware of the several close passes we have seen this year by large asteroids. The last such object, classified "2002MN", passed within 75,000 miles of the earth at a speed of 23,000 miles per hours just over one week ago.

This object was approximately 70-100 meters in diameter, making it similar in size to an object that hit the Tunguska region of Siberia in 1908. That impact resulted in a blast equivalent to 10-15 megatons, leaving an area of devastation that would cover two-thirds of Rhode Island.

While the idea of such an occurrence has been the stuff of science fiction, events such as Tunguska and our recent close calls dictate we take a hard look at the science facts. The experts we are gathering for our event will present detailed information on search efforts, warning systems, possible diversion scenarios and the overall probabilities that we will experience such an event.

Our panelists for the program include:

Brig. Gen. Simon P. Worden, USAF
US Space Command

Dr. Colleen Hartman

Dr. Thomas Morgan

Dr. Brian Marsden
Minor Planet Center
Harvard-Smithsonian Center for Astrophysics

Evan Seamone
University of Iowa College of Law

Dr. Lee Valentine
Space Studies Institute

Rick Tumlinson

Rich Godwin
The Watch

You are cordially invited to attend the program, as well as the buffet lunch that will precede it. Simply RSVP via email at: When RSVP'ing, please provide your name, affiliation and your phone number.

See you at the Roundtable!
