- Shuttle Radar Topography Mission (SRTM) | NASA Earthdata
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
- Digital Elevation Terrain Model (DEM) | NASA Earthdata
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
- Terrain Elevation - NASA Earthdata
NASA's terrain elevation data measure current height and changes in land altitude and are useful for creating digital elevation models
- What is the altitude of the International Space Station?
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
- Orbits - NASA Earthdata
Space-based platforms can be placed in several types of orbits around Earth The three common classes of orbits are low-Earth orbit (approximately 160 to 2,000 km above Earth), medium-Earth orbit (approximately 2,000 to 35,500 km above Earth), and high-Earth orbit (above 35,500 km above Earth) Platforms orbiting at 35,786 km are at an altitude at which their orbital speed matches the planet's
- OpenAltimetry | NASA Earthdata
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
- Air Mass Density | NASA Earthdata
Air mass density is a fundamental property of atmosphere Mixture of gases forming Earth's atmosphere, consisting of nitrogen (∼78%), oxygen (∼21%), water vapor, and other trace gases such as carbon dioxide, helium, argon, ozone, or various pollutants The concentration of water vapor is very variab
- Why do the boiling point of water decrease on climbing up the higher . . .
Water usually boils at 212F or 100C at sea level As you go higher up in the atmosphere (higher altitude), the amount of atmosphere pushing down on you decreases, hence the pressure decreases
