what is magnetosphere of jupiter? The cavity created in the solar wind by the planet's magnetic field how big is the cavity? It extends up to seven million kilometers in the Sun's direction and almost to the orbit of Saturn in the opposite direction which scientist discovered it? UNANSWERABLE were there any exploration done to study on this? Until 2009 eight spacecraft have flown around Jupiter including Pioneer 10, Pioneer 11, Voyager 1 and  Voyager 2 any spacecraft which carried passengers? No. Only automated spacecraft have visited Jupiter has the second one explored any other planets? Yes. Saturn anything remarkable about its history? It was the first to be designed for exploring the outer Solar System who were behind the designing of it? UNANSWERABLE how was their venture honored? It was honored on one of 10 United States Postage Service stamps commemorating unmanned spacecraft exploring each of the then nine planets and the Moon is there any plaque or symbol made for pioneer? Yes. A gold-anodized aluminum plaque featuring the nude figures of a human male and female along with several symbols that are designed to provide information about the origin of the spacecraft any reason behind for making it? IT carries the plaque in the event that either spacecraft is ever found by intelligent lifeforms from other planetary systems which space organization has been carrying out these missions? NASA have they built any station at space? Yes. International Space Station why was it built? To serve as a microgravity and space environment research laboratory in which scientific research is conducted in astrobiology, astronomy, meteorology, physics, and other fields

Astrobiology [SEP] Introduction
Astrobiology, formerly known as exobiology, is an interdisciplinary scientific field concerned with the origins, early evolution, distribution, and future of life in the universe. Astrobiology considers the question of whether extraterrestrial life exists, and if it does, how humans can detect it. Astrobiology makes use of molecular biology, biophysics, biochemistry, chemistry, astronomy, physical cosmology, exoplanetology and geology to investigate the possibility of life on other worlds and help recognize biospheres that might be different from that on Earth. The origin and early evolution of life is an inseparable part of the discipline of astrobiology. Astrobiology concerns itself with interpretation of existing scientific data, and although speculation is entertained to give context, astrobiology concerns itself primarily with hypotheses that fit firmly into existing scientific theories.
