Dec 22, 2025 · NASA's terrain elevation data measure current height and changes in land altitude and are useful for creating digital elevation models.

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 …

Jan 5, 2025 · 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 …

Feb 10, 2025 · The curvature of the Earth can be observed at an altitude of around 35,000 feet or higher, such as when flying in a commercial airplane.

Mar 12, 2025 · As you go higher in altitude, the air becomes less dense, meaning there are fewer air molecules above you exerting pressure. This decrease in air density leads to a decrease in …

Apr 19, 2021 · The satellite altitude over the ocean is the distance from the satellite to the ellipsoid. If you want to deduce the shape of ocean currents and how these change with time …

The stratosphere stops and the mesosphere starts at about 31 miles (50km). The mesosphere stops and the thermosphere starts at 50 - 56 miles (80 - 90 km).

Oct 19, 2021 · Earlier crossing times for a morning platform like Terra mean lower solar elevations leading to more prevalent shadows. This decrease in orbit altitude alters the spatial coverage …

May 23, 2024 · The phenomenon where temperature decreases with an increase in altitude is known as the lapse rate. On average, the temperature drops by approximately 0.6 degrees …

Mar 12, 2025 · Satellites in space are typically located around 100 to 1,200 miles above the Earth's surface. The altitude of a satellite is determined by its intended purpose, such as …
