Screen capture from Windows on Earth showing the coast of Peru with three marked targets, orbital track, and the 10-minute look-ahead. Windows on Earth provides the user a view of Earth from an astronaut's viewpoint, with interactive photorealistic views of Earth as if seen from an altitude of 360 km. [5] The program uses GeoFusion's digital Earth visualization system, which renders accurate ...
A map of Mercury [1] made in the 1910s by astronomer Eugène Michel Antoniadi shows the following albedo features, localized by a grid in which 0° longitude is the (assumed) subsolar meridian. No certain connection has been made between these features and the topographic features viewed on Mercury by the Mariner 10 spacecraft. Mariner 10 ...
The average albedo of Earth is about 0.3. [15] This is far higher than for the ocean primarily because of the contribution of clouds. Earth's surface albedo is regularly estimated via Earth observation satellite sensors such as NASA's MODIS instruments on board the Terra and Aqua satellites, and the CERES instrument on the Suomi NPP and JPSS.
2.99×10 8: The average diameter of the orbit of the Earth relative to the Sun. Encompasses the Sun, Mercury and Venus. [18] Inner Solar System ~6.54 AU 9.78×10 8: Encompasses the Sun, the inner planets (Mercury, Venus, Earth, Mars) and the asteroid belt. Cited distance is the 2:1 resonance with Jupiter, which marks the outer limit of the ...
Albedo map shows the measured difference in surface reflectivity from the surface of a celestial body. Atlas is a special collection of images of a celestial body surface. The images may be from either ground-based or spacecraft sources. Usually a single scale or set of scales is used throughout the atlas.
Albedo Space is an American satellite imaging company founded in 2020. The company is developing a very low Earth orbit satellite which will be able to capture images with a 10 centimeter resolution.
Light is reflected from Earth to the Moon and back to Earth as earthshine. Earthshine is used to help determine the current albedo of Earth. The data are used to analyze global cloud cover, a climate factor. Oceans reflect the least amount of light, roughly 10%. Land reflects 10–25% of sunlight, and clouds reflect around 50%.
Cloud albedo strongly influences the Earth's energy budget, accounting for approximately half of Earth's albedo. [1] [2] Cloud albedo is influenced by the conditions of cloud formation and variations in cloud albedo depend on the total mass of water, the size and shape of the droplets or particles and their distribution in space.
