The first known proposal for a marned-satellite appeared in a story by Edward Everett Hale entitled "The Brick Moon." The story involved a group of young Bostonians who planned to put an artificial satellite into polar orbit for sailors to use to determine longitude accurately and easily.

Science fiction writers, like Jules Verne in France and Edward Everett Hale in America, had discovered one of the most vital elements in the formula for space travel-a fertile imagination. The first known proposal for a marned-satellite appears in a story by Hale entitled "The Brick Moon" published in 1899. The story involved a group of young Bostonians who planned to put an artificial satellite into polar orbit for sailors to use to determine longitude accurately and easily. They planned to send a brick satellite into orbit because the satellite would have to withstand fire very well. The Satellite's 37 inhabitants signaled the Earth in morse code by jumping up and down on the outside of the satellite.

CAPE CANAVERAL AIR FORCE STATION, Fla. – The Cape Canaveral Air Force Station lighthouse takes on a warm glow as dawn breaks and a full moon still shines in the background. The Canaveral light is the only one owned by the U.S. Air Force. In 2000, the Coast Guard transferred ownership of the lighthouse structure and its grounds to the Air Force, which is now responsible for maintaining it. The U.S. Coast Guard continues to operate the beacon as an active navigational aid. The first lighthouse at Cape Canaveral was built near the tip of the Cape in 1848. The structure was only about 60 feet high with a rather dim light powered by whale oil. In 1859, work began nearby on a new, taller iron structure. Construction was halted during the Civil War, and the lighthouse finally was finished in 1868. The structure, with a brick lining inside its iron exterior, was painted with its "daymark" black and white horizontal bands in 1873 to make it easier to identify during the day as a navigation point. Between 1892 and 1894, the lighthouse was dismantled and moved to its new home about a mile from the coast, where it stands today. Photo credit: NASA/Ben Smegelsky

NASA image acquired July 27, 2001 In southwestern Jordan lies an unusual landscape. Mountains of granite and sandstone rise next to valleys filled with red sand. Some of the mountains reach a height of about 1,700 meters (5,600 feet) above sea level, and many have near-vertical slopes. So alien is this landscape, it’s nicknamed “Valley of the Moon,” and it has served as the film set for a movie about Mars. Yet nomadic people have lived here for thousands of years. Declared a protected area in 1998, this unearthly landscape is Wadi Rum. The Advanced Land Imager (ALI) on NASA’s Earth Observing-1 (EO-1) satellite captured this natural-color image on July 27, 2001. The scene includes part of Wadi Rum and an adjacent area to the east. East of the protected area, fields with center-pivot irrigation make circles of green and brown (image upper right). As the earth tones throughout the image attest, the area is naturally arid, receiving little annual precipitation and supporting only sparse vegetation. Between rocky peaks, the sandy valleys range in color from beige to brick. Ancient granite rocks dating from the Precambrian underlie younger rocks, and some of these basement rocks have eroded into rugged, steep-sloped mountains. The granite mountains have risen thanks partly to crisscrossing fault lines under the park. Overlying the granite are sandstones from the Cambrian and Ordovician Periods, as well as loose sands. Lawrence of Arabia, who fought in the Arab Revolt of 1917–1918, made frequent references to Wadi Rum in his book The Seven Pillars of Wisdom. Likewise, a prominent feature of the protected area is named after the book. Several popular sites in Wadi Rum bear Lawrence of Arabia’s name, but whether he actually visited those sites is uncertain.
