Another great "Chris McKay" resource is the made for PBS TV series called
Space Age which includes the episode "Quest for Planet Mars."  This episode
features Chris McKay in several different locations, the Anarctica, deep
sea diving, and I believe one other place.  He discusses at length his
research for Mars and is,
as usual, very candid.  This is an excellent video series, produced by
WQED/Pittsburgh and NHK/Japan and it comes with an Activity Guide,
supported by NSF.  It was produced in 1992 and I've used it every year,
still one of the best current space programs.  It also includes:  Celestial
Sentinels, Yhe Unexpected Universe, To the Moon and Beyond, Mission to
Planet Earth, and What's a Heaven For?  It is narrated by Patrick
Stewart...and in my opinion is almost as good as Carl Sagan's "Cosmos".
Order info # 800-323-4222, ext. 43.  I very highly recommend this.

Have a wonderful school year everybody!
