Title:
Impacts!

Speaker(s):
Sigrid Close

Occasion:
HEPL Seminar

Date of Talk:
2010-4-1

Details:
We review impactors, ranging from dust to asteroid sizes, and the effects these objects have on Earth's system. We also discuss the plasma formation process when an object enters into Earth's system, or impacts a satellite, and howe can prevent future disasters through better characterization.
