, says LOLA principal investigator David Smith with MIT.To send the Mona Lisa into space required flawless digital timing. First, a black and white version of the famous Italian painting was broken into a 152 x 200 pixel grid, with each pixel represented by a number between zero and 4,095 that corresponded to a shade of gray. Those values were then transmitted, one at a time,[url=http://www.supratksocietyvip.com/]supra tk society[/url], in 4,096 discrete bursts at a rate of about 300 bits per second.On the receiving end, LOLA was able to reassemble the precise grayscale values based on the arrival times of each pulse, and NASA says it managed to do so without interrupting the LRO’s primary job of mapping the moon’s elevation and terrain. Where the earth’s atmosphere interfered, causing pixel errors, NASA employed the same error-correction code algorithm used with CDs and DVDs to smooth things over.(MORE: The 19 Best Tweets about Lance Armstrong’s Oprah Interview)“In the near future, this type of simple laser communication might serve as a backup for the radio communication that satellites use,” said Smith. “In the more distant future, it may allow communication at higher data rates than present radio links can provide.”NASA Wants You: The Original 1959 Astronaut Job DescriptionRalph Morse / Time & Life Pictures / Getty Imagesa group portrait of the Project Mercury astronauts in their pressure suits on Jan. 1,http://www.supratksocietyvip.com/, 1959.

Operate and/or observes fixed-base and moving-base simulator tests, serves as subject-under-test, and assists in the analysis of data for the evaluation and development of various boosters and of communication, telemetry, display, vehicle control, environmental-control and other systems involved in launch, atmospheric escape, orbital flight, reentry, landing and recovery. Participates in specialized training exercises such as centrifuge programs to build up tolerances to the motions and forces associated with launch, flight without gravity, and atmospheric reentry, and to develop proficiency and confidence for vehicle operation under such conditions.The letter was dated June 17, 1959, and according to the U.S. National Archives, NASA announced the selection of its first astronauts — known as the “Mercury Seven” — on April 9, 1959.On May 5, 1961, Alan Shepard Jr. became the first American in space on the Mercury spacecraft.
