Launching from New Zealand two weeks apart in May, each satellite will carry a thermal infrared spectrometer. The JPL-designed instruments include specially shaped mirrors and detectors for splitting and measuring infrared light. Similar technology is used by the Mars Climate Sounder on NASA’s Mars ...
题目On Tuesday,NASA sent up a test satellite from New Zealand as part of its experiment with a new orbit around the moon that it hopes to use in the coming years to land astronauts on the lunar surface.If the rest of the mission is successful.the satellite will be...

“Attaching filters directly to the detector eliminates the substantial mass of traditional lens and filter systems,” Hewagama said. “This allows a low-mass instrument with a compact focal plane which can now be chilled for infrared detection using smaller, more efficient coolers. Smaller satellit...
This led to NASA and the National Oceanic and Atmospheric Administration jointly developing the Geostationary Operational Environmental Satellite and discovering Ozone depletion.[4] 【参考译文】美国国家航空航天局(NASA)还发射了多颗不同的卫星来研究地球,例如1960年发射的电视红外观测卫星(TIROS),这是第一颗...
To see a satellite image of the field of space debris that floats around the earth is like looking at fleas swarming an unfortunate dog. About a half-million pieces of debris are the size of a marble, but even tiny pieces that travel more than 17,000 miles per hour could be deadly to...

"We attribute large-scale thermal unrest to the enhancement of underground hydrothermal activity, and suggest that such analysis of satellite-based infrared observations can improve constraints on the thermal budget of volcanoes, early detection of pre-eruptive conditions and assessments of volcanic alert...
Banner Image: On Dec. 5, 2017, the Multi Spectral Imager on the European Space Agency's Sentinel-2 satellite captured the data for a false-color image of the Thomas Fire in Ventura County, California. Active fires appear orange and the burn scars are brown. Unburned vegetation is green; ...
