Moons of Jupiter. A montage of Jupiter and its four largest moons (distance and sizes not to scale) Eight of Jupiter's moons are regular satellites, with prograde and nearly circular orbits that are not greatly inclined with respect to Jupiter's equatorial plane.

Moons of Jupiter

The Galilean satellites are ellipsoidal in shape, due to having planetary mass, and so would be considered dwarf planets if they were in direct orbit about the Sun. The other four regular satellites are much smaller and closer to Jupiter; these serve as sources of the dust that makes up Jupiter's rings.The remainder of Jupiter's moons are irregular satellites, whose prograde and retrograde orbits are much farther from Jupiter and have high inclinations and eccentricities.

These moons were probably captured by Jupiter from solar orbits. There are 16 recently discovered irregular satellites that have not yet been named.

Shuttle Carrier Aircraft and space shuttle mockup to become centerpiece of new exhibit at Space Center Houston visitor center near NASA's Johnson Space Center.

Space Shuttle

Still in its protective shrink wrap, space shuttle Atlantis has been raised and tilted into display position at the Kennedy Space Center Visitor Complex. Atlantis starred in a daylong parade and celebration as the shuttle was moved into an exhibit hall at the Kennedy Space Center Visitor Complex. The storied spacecraft's pair of 60-foot-long doors were closed Sept. 20 during preps for permanent display. NASA's Shuttle Carrier Aircraft pilots will carry Endeavour to its new home in Los Angeles. Moon Base Possible through Lava Tubes. Scientists and theorists had come up with many ideas to open up a functional base on the moon but the issue of radiation outweighs the possibilities.

Moon Base Possible through Lava Tubes

Scientists have recently discovered lava tubes where a base could be safely constructed. In volcanic tubes are now considered to be safe and ideal sites for settling in. Open Space Agency. Why are there dozens of dead animals floating in space? On July 20, 1969, Neil Armstrong became the first man in history to step on the surface of the moon.

Why are there dozens of dead animals floating in space?

Millions of people tuned in to a broadcast of the event, and after Edwin "Buzz" Aldrin Jr. joined Armstrong, the two spent about two and a half hours gathering lunar rocks to bring back for analysis. The success was a triumph, not just for the United States, but for mankind, the imagination and the possibilities of exploration.

What many people don't know, however, are the special sacrifices that had to be made in order to get astronauts up into space at all. The major unsung heroes of space exploration, it turns out, are animals. Before space programs started sending people up into orbit, scientists couldn't agree on what it would be like for a living organism to leave Earth's atmosphere. Mars One. The Space Race. By the mid-1950s, the U.S.

The Space Race

-Soviet Cold War had worked its way into the fabric of everyday life in both countries, fueled by the arms race and the growing threat of nuclear weapons, wide-ranging espionage and counter-espionage between the two countries, war in Korea and a clash of words and ideas carried out in the media. These tensions would continue throughout the space race, exacerbated by such events as the construction of the Berlin Wall in 1961, the Cuban missile crisis of 1962 and the outbreak of war in Southeast Asia.
