Adventures of Space

The  International Space Station  ( ISS ) is a  space station  (habitable  artificial satellite ) in  low Earth orbit . The  ISS programme  is a joint project between five participating space agencies:  NASA  ( United States ),  Roscosmos  ( Russia ),  JAXA  ( Japan ),  ESA ( Europe ), and  CSA  ( Canada ). The ownership and use of the space station is established by intergovernmental treaties and agreements The ISS serves as a  microgravity  and  space environment  research laboratory in which crew members conduct experiments in  biology ,  human biology ,  physics ,  astronomy ,  meteorology , and  other fields . The station is suited for the testing of spacecraft systems and equipment required for missions to the Moon and Mars. The ISS  maintains an orbit  with an average altitude of 400 kilometres (250 mi) by means of reboost manoeuvres using the engines of the  Zvezda  module or visiting spacecraft. It circles the Earth in roughly 92 minutes and completes 15.5 orbits per day.

Humans have always looked up into the night sky and dreamed about space. In the latter half of the 20th century, rockets were developed that were powerful enough to overcome the force of gravity to reach orbital velocities, paving the way for space exploration to become a reality. want to know more about space history ,visit https://adventuresofspace.blogspot.com/p/history.html

Yuri Alekseyevich Gagarin was a Soviet Air Forces pilot and cosmonaut who became the first human to journey into outer space, achieving a major milestone in the Space Race; his capsule Vostok 1 completed one orbit of Earth on 12 April 1961.   Space missions:  Vostok 1 Nationality:  Soviet Gagarin's flight came at a time when the United States and the Soviet Union were competing for technological supremacy in space. The Soviet Union had already sent the first artificial satellite, called  Sputnik , into space in October 1957.

   Universe , the whole cosmic system of matter and  energy  of which  Earth , and therefore the  human race , is a part. Humanity has traveled a long road since societies imagined Earth, the  Sun , and the  Moon  as the main objects of creation, with the rest of the universe being formed almost as an afterthought. Today it is known that Earth is only a small ball of rock in a  space  of unimaginable vastness and that the birth of the  solar system  was probably only one event among many that occurred against the backdrop of an already mature universe.
