The New York Times reports that the latest concerns around the space shuttle Discovery revolve around some protruding pieces of cloth that could cause uneven heating on reentry and so on. Again, I am astounded by the materials used to build this marvel of modern engineering: the Times describes this cloth as a "feltlike" material. So here's what we have so far:
1) Felt cloth
I'd like to recommend these additional materials, all available at your local craft shop:
1) Popsicle sticks
2) Scrapbooking paper
3) Lanyard plastic
4) Those little puffballs with the feet and googly eyes. You could stick these to the outside of the shuttle portholes during a spacewalk and then say, "Look! Martians!" That would be a surefire, inexpensive way to give the space program a boost.
