Laboratory scientist Catherine Plesko will talk about asteroids at two Café Scientifique talks in Santa Fe, and Los Alamos.
The talk is titled “Deflection of Earth-Bound Asteroids,”and she will talk at the Santa Fe Complex (near the Santa Fe Railyard), 624 Agua Fria Street, Santa Fe at 6:45 tonight.
Then on Thursday at 6:45 p.m., Plesko will give her talk at the Los Alamos Research Park.
High school students and the general public are invited to attend.
“Day and night, little pieces of asteroids and cometsóthe crumbs left over from the formation of the planets in our solar system — rain down on our Earth in the form of meteors,”Plesko said. Although most of these objects are small, once in a while something larger comes our way. This can either be deflected, where the object is pushed off course, or dispersed, where the object is blown apart.
Plesko will discuss the various options of dealing with Earth-bound asteroids, which are being explored using Earth-based computer simulations and small experiments. “Our goal is to come up with a plan long before a hazardous object is found to be coming at us,” she said.
Café Scientifique is a popular program that brings teens and experts working on the cutting edge of scientific research together to explore, discuss, and debate the latest ideas in science and technology. The program is free, food and drink are provided, students are compensated for carpooling, and participants are eligible to win door prizes.
