Space agencies, governments, researchers and commentators have isolated a large number of direct and indirect benefits of space exploration programs including: New technologies that can be utilized in other industries and society (such as the development of communications satellites) Improved knowledge of space and the origin of the universe.
Planet's Dove satellites are CubeSats that weigh 4 kilograms (8.8 lb), 10 by 10 by 30 centimetres (3.9 in × 3.9 in × 11.8 in) in length, width and height, [14] orbit at a height of about 400 kilometres (250 mi) and provide imagery with a resolution of 3–5 metres (9.8–16.4 ft) and are used for environmental, humanitarian, and business ...
Planetary science. A geological map of the Sputnik Planitia basin on the dwarf planet Pluto. Analysis of planetary surfaces and surface features is a major component of planetary science. Planetary science (or more rarely, planetology) is the scientific study of planets (including Earth ), celestial bodies (such as moons, asteroids, comets) and ...
Space mirrors in orbit around the Earth, as designed by Hermann Oberth, are intended to focus sunlight on individual regions of the earth's surface or deflect it into space. It is therefore not a question of the weakening of the solar radiation on the entire exposed surface of the Earth, as would be the case when considering the establishment ...
Earth science or geoscience includes all fields of natural science related to the planet Earth. [ 1] This is a branch of science dealing with the physical, chemical, and biological complex constitutions and synergistic linkages of Earth's four spheres: the biosphere, hydrosphere / cryosphere, atmosphere, and geosphere (or lithosphere ). Earth ...
Science is a strict systematic discipline that builds and organises knowledge in the form of testable hypotheses and predictions about the world. [1] [2] Modern science is typically divided into three major branches: [3] the natural sciences (e.g., physics, chemistry, and biology), which study the physical world; the social sciences (e.g., economics, psychology, and sociology), which study ...
Planet Earth II is a natural history documentary series, produced by the BBC as a sequel to the highly successful Planet Earth television series, which aired roughly a decade earlier, in 2006. [8] The series was presented and narrated by Sir David Attenborough with the score composed by Hans Zimmer .
Earth formed in this manner about 4.54 billion years ago (with an uncertainty of 1%) [25] [26] [4] and was largely completed within 10–20 million years. [27] In June 2023, scientists reported evidence that the planet Earth may have formed in just three million years, much faster than the 10−100 million years thought earlier.
