![]() ![]() Debating which images should or shouldn’t have been ranked, and how high, would be an appropriate way to mark the past half century of NASA’s accomplishments. We welcome the discussion we know this list will spark. Although a satellite had returned a picture of the whole Earth in 1967, it wasn’t until humans saw this view for the first time a year later that it entered our collective mind. This particular shot was from Apollo 17, but all of the moon-bound astronauts took similar photos. Used significantly by the environmental movement (although NOT, as often reported, the inspiration for Earth Day). Topping the list is the view of the whole Earth above, arguably the most influential image to come out of the American space program. Our only excuse is that the ranking reflects the affinity of the division of space history staff for space topics. ![]() ![]() We also recognize that, even though the first “A” in NASA stands for “aeronautics,” our list is light on aeronautical breakthroughs. Photos from the Apollo moon program predominate, as well they should-it remains the agency’s crowning achievement. Here you’ll find information and analysis on all the company’s latest endeavors. The list omits significant events from space history that were not NASA achievements, such as the famous 1958 photograph of Wernher von Braun and the other architects of the Explorer 1 satellite celebrating their success by holding a model of the satellite over their heads, an event that occurred months before NASA existed. Looking to keep up with all the latest SpaceX news You’ve come to the right place. This instructable contains directions for. Many wonderful images did not make the final cut-we couldn’t convince the editors to give us 20 pages instead of 10.

The rationale for why any one image ranked two slots higher than any other combines several factors, including our attempt to balance the list between human spaceflight, satellite imaging, and planetary exploration. 1 Get Automatically Changing NASA HD Space Wallpapers on Windows. We recognize that any such ranking is inherently subjective. Hester, A.On the occasion of the 50th anniversary of the National Aeronautics and Space Administration, which began its operations on October 1, 1958, we offer this list of the 50 most memorable images from NASA’s history ( see all 50 in the photo gallery below). The Crab Pulsar rotates about 30 times each second. In the nebula's very center lies a pulsar: a neutron star as massive as the Sun but with only the size of a small town. The Crab Nebula spans about 10 light-years. The above image, taken by the Hubble Space Telescope, is presented in three colors chosen for scientific interest. The filaments are not only tremendously complex, but appear to have less mass than expelled in the original supernova and a higher speed than expected from a free explosion. ![]() The Crab Nebula, the result of a supernova seen in 1054 AD, is filled with mysterious filaments. This is the mess that is left when a star explodes.

McCandless and fellow NASA astronaut, Robert Stewart, were the first to experience such an tethered space walk during a Space Shuttle mission in 1984. Guided by a Manned Maneuvering Unit MMU), astronaut McCandless, pictured above, was floating free in space.
