The Copernican Revolution dethroned Earth to just one of many planets orbiting the Sun. Proper motion was mentioned by Halley. William Herschel found that the Solar System is moving through space within our disk-shaped Milky Way galaxy. Edwin Hubble showed that the Milky Way galaxy is just one of many galaxies in the universe.
This event, plus research indicating that actively photographing the Earth has positive psychological effects, caused Yaden et al. to posit that studying the overview effect might improve understanding of psychological well-being in isolated, confined, extreme (ICE) environments such as space flight. [3] Early photos of Earth taken from space ...
GTO is a highly elliptical Earth orbit with an apogee (the point in the orbit of the moon or a satellite at which it is furthest from the earth) of 42,164 km (26,199 mi), [3] or a height of 35,786 km (22,236 mi) above sea level, which corresponds to the geostationary altitude.
[nb 1] Earth's orbital speed averages 29.78 km/s (19 mi/s; 107,208 km/h; 66,616 mph), which is fast enough to cover the planet's diameter in 7 minutes and the distance to the Moon in 4 hours. [3] The point towards which the Earth in its solar orbit is directed at any given instant is known as the "apex of the Earth's way". [4] [5]
The Earth's terrain varies greatly from place to place. About 70.8% [ 18 ] of the surface is covered by water. The sea floor has mountainous features, including a globe-spanning mid-ocean ridge system, as well as undersea volcanoes , [ 19 ] oceanic trenches , submarine canyons , oceanic plateaus , and abyssal plains .

Operating Manual For Spaceship Earth is a short book by R. Buckminster Fuller, first published in 1969, following an address with a similar title given to the 50th annual convention of the American Planners Association in the Shoreham Hotel, Washington D.C., on 16 October 1967. [1] The book relates Earth to a spaceship flying through space.
