Earth Orbiting Satellites

Observing Satellites from your Backyard.

• A few of the best and brightest from spaceweather.com

Communication Satellites

• Different systems and their companies (from Univ of Alberta).

Weather Satellites

• National Oceanic and Atmospheric Administration (NOAA) synopsis of weather satellites.
• NOAA details of U.S. weather satellites (GOES and POES).
• Links to many weather satellites.
• Satellite images updated regularly from The Weather Channel. Scroll down to U.S. Satellite Pictures and try the time lapse loops (right column of links). Ditto for International Satellites to see the weather on other continents.
• Maps of lightning strikes can also be interesting.

Landsat

• Landsat Program Homepage (links to other sites).
• Landsat 7, the latest and greatest.
• Landsat 7 Image Gallery (I really recommend this!).
• Internet access to Landsat photos (cost $10 for B/W, $16 for color ... sorry!).

Global Positioning System (GPS)

• US Navy GPS page (they developed GPS).
• GPS and a history of navigation (suggested by Rebecca of Craft High School, VA; thanks!)
• GPS resources suggested by an online colleague (thanks!).
• Car GPS from LelandWest (suggested by another online colleague, thanks!).
• GPS from ASAP Motors (suggested by a 6th grade class in Lexingon, VA, thanks!)
• Resources for mapping, GIS, GPS, etc (suggested by a Girl Scout troop in WA, thanks!).

Surveillance "Spy" Satellites

• Hmmm, I couldn't find any web pages from the military... big surprise!
• This one sounds pretty knowledgeable, but take it with a grain of salt. I personally am not familiar with the Federation of American Scientists, so can't vouch for their truthfulness (don't believe everything you read on the web!). Here, they give links to different satellite systems (scroll down to Space).

Manned Space Stations

• Skylab (1973-1979).
• U.S. Space Shuttle (1981- )
• Russian Mir Space Station (1986- ), NASA involvement in Mir.
• International Space Station "Freedom" (1998- )

Astronomy Telescopes

• The Hubble Space Telescope (HST) - an optical telescope.
• The Next Generation Space Telescope - a replacement for HST, now being designed.
• The Chandra X-Ray Observatory - another of NASA's "Great Observatories".
• The Compton Gamma-Ray Observatory (GRO) - ditto.
• The Space Infrared Telescope Facility (SIRTF) - double ditto (this one is still being built).
• And there are many more, including old, defunct telescopes and current, smaller (often more specialized) telescopes.
