Descrizione : Silk cachet with Mamoru Mohri, NASDA. Houston secial post stamp celebrating STS-99 mission.
SRTM consisted of a specially modified radar system that flew onboard Endeavour during its 11-day mission. This radar system gathered around 8 terabytes of data to produce high-quality 3-D images of the Earth`s surface.
The Shuttle Radar Topography Mission mast was deployed successfully to its full length, and the antenna was turned to its operation position. After a successful checkout of the radar systems, mapping began at 00:31 EST, less than 12 hours after launch. Crewmembers split into two shifts so they could work around the clock, and began mapping an area from 60 degrees north to 56 degrees south. Data was sent to the Jet Propulsion Laboratory for analysis, and early indications showed the data to be of excellent quality.
