After an Astronaut completes a space mission, lasting from one week to six months, they are transported from a weightless environment to normal gravity.
Re-adapting to Earth’s gravity is hard because their muscles and bones have weakened, and the heart has to work much harder to pump blood around the body.
Astronauts returning back in a spacecraft have to be helped out by rescue staff, and they are carried to waiting helicopters for the first part of their journey home.
Some feel lightheaded, some may faint, while others may also have trouble standing up, walking, turning corners and keeping a sense of balance. If they close their eyes, they are likely to fall over. Even sleeping can be difficult.
Remote sensing science is considered a new science of the 20th century, where it was introduced initially in response to a sharp demand for it during the 1st and 2nd World Wars. They were used initially for military purposes, including reconnaissance and detection of the movements of groups of soldiers and identification of the topography of the land in order to develop detailed military plans. The most known spying military program was the American CORONA program, which used to photograph sensitive areas around the world with an accuracy of 2 meters during the period from 1960 to 1972. The said program was uncovered only in 1995 when more than 800 thousand aerial photos were made available for civilian use to allow scientists, specialists and researchers in the various fields to study, analyse and use them
Space telescopes or space observatories are spacecrafts that gather information about outer space using different frequency ranges such as gamma ray, x-ray, ultraviolet, visible, infrared, microwave and radio.
