Bringing ESA’s Sentinel-3 Mission Together
2013-03-06 11:27:53

ESA An important milestone has been reached for ESA´s Sentinel-3 mission. The satellite platform has been delivered to the Prime Contractor in France where the instruments will be installed and tested along with the numerous components that make up this sophisticated new mission to monitor Earth. Once complete, Sentinel-3 will host an array of state-of-the-art instruments that mainly focus on measuring different aspects of ocean waters, such as the temperature and color of the...

Mapping Forest Biomass To Understand The Global Carbon Cycle
2013-02-05 10:54:59

ESA Satellite radar data are being used to map Earth´s vital resources. The latest advances and applications of the POLinSAR remote sensing technique were highlighted at a conference held last week. Polarimetric InSAR — or POLinSAR — is a remote sensing technique based on polarimetric information in Synthetic Aperture Radar (SAR) images. With this technique, a radar sends polarised pulses towards the target, and the information in the signals backscattered from Earth...

The detection and recognition of an object with small RCS, such as a stealth target, is the most difficult problem to solve for the modern radar system. Professor Hu Cheng and his group at Radar Research Lab, Beijing Institute of Technology set out to tackle this problem. After seven years of innovative research, they have developed a series of methods to detect, track and recognize some targets with small RCS. In particular, they proposed a novel imaging method based on the principle...

New Views Of Earth From Space Possibly Revealed By Short Wavelength Radar
2012-10-04 11:26:18

As our quest for knowledge about our planet grows, so does the need for novel technologies to offer new insight into the changing face of Earth. Researchers are excited about the potential of a new radar wavelength to image Earth from space. As part of ESA´s continuing efforts to develop new and better instruments for observing Earth from space, a field experiment has been exploring a very short radar wavelength — only 8.5 mm — called Ka-band. Since it can offer both...

Mapping Landslides In The Swiss Alps
2012-09-26 08:41:24

Archived radar data from the Envisat mission are playing an important role in mapping landslides in Switzerland. The mission´s vast archives continue to prove useful for mapping ground deformation. Landslides are a natural hazard of special relevance in Alpine regions. This ground displacement can severely damage human lives and infrastructure. Earth-observing satellites — specifically those equipped with radars — can help scientists to map and monitor ground movement....

NASA Software Award Won By QuakeSim And NASA Mobile App
2012-09-21 14:36:26

NASA software that models the behavior of earthquake faults to improve earthquake forecasting and our understanding of earthquake processes, and NASA's first mobile application are co-winners of NASA's 2012 Software of the Year Award. The award recognizes innovative software technologies that significantly improve the agency's exploration of space and maximize scientific discovery on Earth. QuakeSim, developed at NASA's Jet Propulsion Laboratory in Pasadena, Calif., is a comprehensive,...

ESA Under Press To Launch Sentinel Missions
2012-06-08 03:22:58

The loss of the Envisat satellite is affecting services by Europe´s Global Monitoring for Environment and Security program. Efforts are being coordinated with other space agencies to fill some of the gaps, but the situation adds further urgency to launch the Sentinel missions. Carrying an array of sophisticated instruments, Envisat provided a continuous stream of information about the state of our planet for 10 years. Envisat not only advanced science, but also supplied data for...

Endeavour launched from Kennedy Space Center on April 9. 1994 at 7:05 AM EDT and landed at Edwards AFB on April 20 at 9:54 AM PDT. The shuttle orbited 183 times at an altitude of 121 nautical miles at an inclination of 57 degrees and travelled 4.7 million miles. The mission lasted  11 days, 5 hours, 49 minutes, and 30 seconds. The primary payload was the Space Radar Laboratory (SRL-1), located in payload bay; activated by crew and operated by teams on ground. SRL-1 included the Spaceborne...
