Space Shuttle Orbiter Diagram

The forward rockets of the Reaction Control System, located near the nose of the Space Shuttle orbiter, included 14 primary and two vernier RCS rockets. The aft RCS engines were located in the two Orbital Maneuvering System (OMS) pods at the rear of the orbiter, and these included 12 primary (PRCS) and two vernier (VRCS) engines in each pod. The PRCS system provided the pointing control of the...

Hubble Telescope Images Black Holes

The Hubble telescope was built by the United States space agency NASA with contributions from the European Space Agency. The Space Telescope Science Institute (STScI) selects Hubble's targets and processes the resulting data, while the Goddard Space Flight Center controls the spacecraft. Space telescopes were proposed as early as 1923. Hubble was funded in the 1970s, with a proposed launch in...

Solar System Outline Printable

The Solar System formed 4. 6 billion years ago from the gravitational collapse of a giant interstellar molecular cloud. The vast majority of the system's mass is in the Sun, with the majority of the remaining mass contained in Jupiter. The four smaller inner planets, Mercury, Venus, Earth and Mars, are terrestrial planets, being primarily composed of rock and metal. The four outer planets are...

A battle always has as its purpose the reaching of a mission goal by use of military force. A victory in the battle is achieved when one of the opposing sides forces the other to abandon its mission and surrender its forces, routs the other (i. e. , forces it to retreat or renders it militarily ineffective for further combat operations), or even completely annihilates the latter resulting in...

Space Shuttle Discovery Smithsonian

By its last mission, Discovery had flown 149 million miles (238 million km) in 39 missions, completed 5,830 orbits, and spent 365 days in orbit over 27 years. Discovery flew more flights than any other Orbiter Shuttle, including four in 1985 alone. Discovery flew all three "return to flight" missions after the Challenger and Columbia disasters: STS-26 in 1988, STS-114 in 2005, and STS-121 in...
