Photojournal: NASA's Image Access Home Page Orbiting Earth 101: What You’d See / What You’d Do “I saw for the first time the earth’s shape. I could easily see the shores of continents, islands, great rivers, folds of the terrain, large bodies of water. The horizon is dark blue, smoothly turning to black. . . the feelings which filled me I can express with one word–joy.” -Yuri Gagarin It takes a tremendous amount of energy to do any type of heavy lifting, and the most extreme example of this is lifting something all the way up off of the Earth, out of the atmosphere, and into space! And once you’re up there, at least 300 km above the Earth’s surface, the sights you’ve got are bound to be absolutely amazing! But gravity is a funny thing. But while the Moon is 384,000 km away from the center of the Earth and takes about four weeks to orbit the Earth, these man-made satellites and space vehicles, at an altitude of around 300 km, are only 6,700 km away from the center of the Earth.

The Luminarium - International Artgroup Boeing X-37 The Boeing X-37, also known as the X-37 Orbital Test Vehicle (OTV), is an American reusable unmanned spacecraft. It is boosted into space by a rocket, then re-enters Earth's atmosphere and lands as a spaceplane. The X-37 is operated by the United States Air Force for orbital spaceflight missions intended to demonstrate reusable space technologies. It is a 120%-scaled derivative of the earlier Boeing X-40. As of 2013[update] it holds the world record for being the smallest robotic, unmanned space plane. The X-37 began as a NASA project in 1999, before being transferred to the U.S. Department of Defense in 2004. It conducted its first flight as a drop test on 7 April 2006, at Edwards Air Force Base, California. Development Origins In 1999, NASA selected Boeing Integrated Defense Systems to design and develop an orbital vehicle, built by the California branch of Boeing's Phantom Works. 1999 artist's rendering of the X-37 spacecraft.

NASA Space Telescope Takes Its First X-Ray Photos of a Black Hole | NuSTAR NASA's newest space telescope has opened its X-ray eyes to take its first pictures of the high-energy universe, including a glimpse at a well-known black hole. The space observatory, called the Nuclear Spectroscopic Telescope Array, launched June 13 on a mission to observe high-energy, short-wavelength X-ray light from some of the most dynamic objects in space, such as black holes and supernova remnants. The observatory extended a 33-foot (10 meters) mast on June 21 to separate its light-gathering optics from their focal point. The $165 million telescope took its first photos June 28, directing its gaze toward a nearby black hole that is eating up a neighboring giant star. The black hole, called Cygnus X-1 is extremely bright in X-rays. "Today, we obtained the first-ever focused images of the high-energy X-ray universe," said Fiona Harrison, the mission's principal investigator at the California Institute of Technology in Pasadena, Calif., in a statement. 0 of 9 questions complete

5 things about Friday's space events By Elizabeth Landau, CNN About 1,000 people have been injured in Russia as the result of a meteor exploding in the air. The energy of the detonation appears to be equivalent to about 300 kilotons of TNT, said Margaret Campbell-Brown of the department of physics and astronomy at the University of Western Ontario. Meanwhile, an asteroid approached Earth but did not hit it Friday, coming closest at about 2:25 p.m. You probably have some questions about both of those events, so here's a brief overview: 1. The meteor in Russia and the asteroid that passed by on Friday afternoon are "completely unrelated," according to NASA. Estimates on the meteor's size are preliminary, but it appeared to be about one-third the size of 2012 DA14. The term "asteroid" can also be used to describe the rock that exploded over Russia, according to the European Space Agency and NASA, although it was a relatively small one. 2. According to NASA, here’s how you tell what kind of object is falling from the sky: 3. 4. 5.
