(meteorobs) Lecture on meteor and comets
I thought this lecture might be of interest to our group particularly
since it will be available on the internet.

FOR IMMEDIATE RELEASE
June 12, 2002
FREE LECTURES LINK SPACE ROCKS AND EARTH LIFE
The influence of asteroids and comets on life on Earth will be the
topic of two free,
public
lectures entitled "Comets, Asteroids and the Interplanetary Shooting
Gallery" at NASA's Jet
Propulsion Laboratory on Thursday, June 20, and at Pasadena City College
on Friday, June 21.
Dr. Don Yeomans, head of NASA's Near Earth Objects program office,
will discuss how
comets and asteroids brought the building blocks of life to the young
Earth and how later
impacts
caused worldwide extinctions. He will also describe steps being taken
today to detect
potentially
hazardous comets and asteroids.
Liquid water, carbon-based molecules and a relatively stable
environment are critical
elements for life. Comets and asteroids can bring water and the
chemicals on which life is
based,
but can also bring widespread destruction. If future impacts are
inevitable, what should we do?
Both lectures begin at 7 p.m. Seating is on a first-come,
first-served basis. The JPL
lecture
will be webcast live and will be available after the event at
http://www.jpl.nasadot gov/events/lectures/jun02.html .
The lecture at JPL, located at 4800 Oak Grove Dr., Pasadena, off
the Oak Grove Drive exit
of the 210 (Foothill) Freeway, will be held in the von Karman
Auditorium. The Friday lecture
will
be held in Pasadena City College's Vosloh Forum at 1570 E. Colorado
Blvd.
