Impact, are you worried about impact hazards? Explain your position
in one paragraph and give two reasons to support your position. Use
proper references. Your answer is due at the beginning of class.

Reading assignment due:
Pale Blue Dot, chapters 17 & 18.
Be prepared to discuss the following questions:
What is SL9?
What happened to it in 1994?
What do you think about a manned mission to an asteroid?
How are asteroid impacts the proverbial "marsh of Camarina"?
Which do you think is more worrisome: accidental impact or purposeful impact?
Should we develop the technology to change asteroid orbits?
Sagan states, "...the only foreseeable solution is a combination of ... and effective public education... This is a job for NASA". Is NASA doing this job?
Do you think that we should continue to search for NEOs?
Do you agree with Sagan's "future involvement with near-Earth asteroids" timeline on pages 323-324?
How does Sagan's timeline from Pale Blue Dot compare with Solem's timeline as stated on p.30 of "Comet Busters"? Do you agree with either?
One of the newest deflection techniques involves the Yarkovsky effect. We have the technology to employ this technique now. How does this fact affect your opinion on development of deflection techniques as discussed by Sagan in chapter 18 of Pale Blue Dot? Since we have the technology, does this increase the risk of a madman sending an impact down on earth?
