2025年1月5日 · The International Space Station (ISS) orbits Earth at an average altitude of approximately 420 kilometers (260 miles) above the Earth's surface. This altitude allows the ISS to remain in a stable ...

2025年3月20日 · NASA's terrain elevation data measure current height and changes in land altitude and are useful for creating Digital Elevation Models.

6 天之前 · NASA's data for digital elevation models (DEM) comes from airborne and space-based sources and are useful for analyzing a majority of Earth's terrain.

What is Remote Sensing? Remote sensing is the acquiring of information from a distance. NASA observes Earth and other planetary bodies via remote instruments on space-based platforms (e.g., satellites or spacecraft) and on aircraft that detect and record reflected or emitted energy. Remote instruments, which provide a global perspective and a wealth of data about Earth systems, enable data ...

2000年2月11日 · The Shuttle Radar Topography Mission (SRTM) payload flew aboard the Space Shuttle Endeavour during the STS-99 mission. SRTM collected topographic data over nearly 80% of Earth's land surfaces, creating the first-ever near-global dataset of land elevations. The SRTM payload consisted of two radar antennas, one located in the shuttle's payload bay and the other installed on the end of a 200-foot ...

NASA’s OpenAltimetry is a free and powerful map-based data visualization and discovery tool for exploring surface elevation profiles from the Ice, Cloud, and land Elevation Satellite-2 (ICESat-2) and ICESat platform mission altimetry data. With OpenAltimetry, users can explore how different types of surface heights have changed across Earth over time.

NASA's Commercial Satellite Data Acquisition (CSDA) program has acquired commercial datasets from Maxar for scientific purposes.

RAP), which was funded under the NASA Instrument Incubator Program (IIP) [1]. HIWRAP is a dual-frequency (Ka- and Ku-band), dual-beam (300 and 400 incidence angles), conical scanning, Doppler radar system designed for operation on the NASA high-altitude (65,000 ft) Global Hawk Unmanned Aerial System (UAS). It utilizes solid state transmitters along with a novel pulse compression scheme that ...

ve study of East Coast snowstorms in 30 years. IMPACTS will fly a complementary suite of remote sensing and in-situ instruments for three 6-week deployments (2020-2023) on NASA’s ER-2 high-altitude aircraft and P-3 cloud-sampling aircraft. The first deployment began on January 17, 2020, and ended on March 1, 2020. IMPACTS samples U.S. East Coast winter storms using advanced radar, LiDAR, and ...

2025年3月25日 · We will produce a long-term observational dataset of daily, near-global US/M temperature profiles from roughly 25-80 km altitude covering 1991 to the present. This unique and valuable new record spanning over 20 years will facilitate studies that advance our understanding of US/M processes, how those processes are affected by climate change ...
