STS-99 - Payload: EarthKAM

EarthKAM is a NASA-sponsored program that enables middle school students to
take photographs of the Earth from a camera aboard the Space Shuttle. During
missions, students work collectively and use interactive web pages to target images
and investigate the Earth from the unique perspective of space.
An electronic still camera (ESC) bracket-mounted to the overhead starboard
window of the orbiter aft flight deck will face the nadir to observe various
student-selected sites on Earth. Other than equipment setup, initial camera
pointing, and possible camera lens changes, no crew intervention is required for
nominal operations.
The University of California at San Diego houses the EarthKAM Mission Operations
Center (MOC). Most participating schools (or group of schools) establish a Student
Mission Operation Center (SMOC) whose computers are connected to the Internet
for a number of purposes:
To communicate with other SMOC teams and EarthKAM personnel
To obtain the latest weather information
To track the Shuttle's orbit
To select and submit target requests
How EarthKam Works
Before the mission, students select a topic of interest, such as human settlement
patterns, mountain ranges, or agricultural patterns. Then they define investigations
that will be supported by the EarthKAM images.
During the mission, each SMOC submits a number of photo requests through
specialized EarthKAM web pages. The requests are processed and uplinked to the
EarthKAM ESC aboard the Shuttle.
After the ESC takes the pictures, digital images are sent back to Earth and posted
on the data system for the students to use in their investigations. For their final
reports, students use these new images along with other relevant images from the
full EarthKAM image set. Scientists and educators review the original proposal and
the final report to provide feedback to the students.
The EarthKAM program also is preparing to mount a camera aboard the
International Space Station.
History/Background
During the first four missions of EarthKAM, students took more than 2,000
high-resolution digital images of the Earth. These photographs included the
Himalayas, clouds over the Pacific, volcanoes, and recent forest fires in Indonesia.
