[blue text] EarthKAM Concept [/blue text]
• Middle school students control and Earth-looking camera on the Space Shuttle
• "Mission Control Center" at UCSD makes this possible

[blue text] Scenario [/blue text]
• Digital camera mounted in Space Shuttle Window (by astronauts)
• Commanded from ground (by middle School students, thru UCSD)
• Takes photos of the Earth
• Photos put on web for students (~hours)

[blue text] History [/blue text]
• Begun ~3 years ago
• Flown on 4 Space Shuttle flights
• Gradual scaling of:
   - Control Center architecture (UCSD) (computing, network, storage)
   - Number of participating schools (from 3 to 95)

[blue text] 4 components of Earthkam [/blue text]
• Space Shuttle and camera
• Kids in classrooms
• UCSD Control Center (links the two)
• Image archive (www)

[blue text] Shuttle/Camera [/blue text]
• Shuttle
   - altitude ~ 150-300 miles
   - speed ~ 5mi/sec (!)
• Camera
   - Nikon with Kodak back (2 K x 3K CCD)
   - 18 MB TIF color images (~70 km x 100 km)
   - 260 MB PCMCIA card
   - SCSI to ThinkPad (with Earthkam software)

[blue text] Classrooms [/blue text]
• Before the Shuttle flight: Curriculum 
   - Gepgraphy (maps, etc.)
   - Earth Science
   - Math; technology
   - Space Science (earth/sun; orbits)
• After the flight: "Research Projects"
   - e.g. dedorestation, wetlands, etc., using images
• During the flight: "SMOC"
