When: Sunday, December 7, 2014, 10:00am – 12:00 noon
Where: Salida Community Center, 305 F St (corner of 3rd and F), Salida
Topic: Space Shuttle Radar Topography Mission
Speaker: Dominic Gorie (Captain, USN, RET.)
Dominic Gorie will present a talk on an international space shuttle radar topography mission (STS-99) at the Central Colorado Humanists’ Sunday Science meeting, 10:00 – Noon on December 7 at the Salida Community Center.
Please join the Humanists for this free, public, monthly Sunday Science meeting. Light refreshments will be served.
Summary of the STS-99 mission:
The Shuttle Radar Topography Mission (SRTM) conducted in February 2000 was an international project spearheaded by the National Imagery and Mapping Agency and NASA, with participation of the German Aerospace Center DLR. Its objective was to obtain the most complete high-resolution digital topographic database of the Earth. 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.
SRTM used C-band and X-band interferometric synthetic aperture radar (IFSAR) to acquire topographic data of Earth’s land mass between 60°N and 56°S. Besides contributing to the production of better maps, these measurements could lead to improved water drainage modeling, more realistic flight simulators, better locations for cell phone towers, and enhanced navigation safety.
The SRTM 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 less than 12 hours after launch. Crew members 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 were sent to the Jet Propulsion Laboratory for analysis, and early indications showed the data to be of excellent quality. 99.98% of the planned area was successfully mapped.

NASA Astronaut (FORMER)
Dom Gorie obtained a Bachelor of Science degree in ocean engineering from the U.S. Naval Academy in 1979. He received a Master of science degree in aviation systems from the University of Tennessee in 1990.
He served as a US naval aviator for 24 years, including flying 38 combat missions in Operation Desert Storm. He accumulated over 6700 flying hours in more than 35 aircraft, making over 600 carrier landings, and he received numerous flying awards and commendations throughout his naval career.
As a NASA astronaut, Gorie is a veteran of four space flights and has logged over 47 days in space. He served as pilot aboard space shuttle STS-91 in 1998 and STS-99 in 2000, and was the crew commander on STS-108 in 2001 and STS-123 in 2008. He retired to Salida in June 2010 and now enjoys skiing, bicycling, fishing, and hiking with his family.
