    - ISS is at about 250 mile, 400klicks, I beleive. - ebnelson - 3/1/2002 10:04:18 AM
      - www.space.gc.ca indicates a research sat at 600 km and they are at 300 km. If you have followed sunblok posts, then should you be using Coppertone SPF-8 or SPF-45 n/t (n/t) - sunblok - 3/1/2002 10:15:47 AM
