CE1 ***** User ID: 15218408 United States 08/27/2012 11:45 PM Report Abusive Post Report Copyright Violation | URIOSITY TAKES ITS FIRST DRIVE, LEAVING MORSE CODE ON MARS NASA/JPL By Megan Garber The Atlantic August 23, 2012 1 Comments When the creators of Curiosity built the rover that would explore Mars, they gave its wheels special treads. The marks left by Curiosity's tires as they tool through the dust of the Martian soil won't just serve as visual odometry markers, allowing Curiosity's engineers to determine the rover's orientation and distance traveled; they'll also send a message. Specifically, this message: short long long long short long long short short long short short Which is also to say, in Morse code: . - - - . - - . . - . . Which is also to say, translating that code: J-P-L, the acronym for NASA's Jet Propulsion Laboratory -- Curiosity's creator. Yes. A calling card, coded into Curiosity's every move. Which was feasible for JPL engineers this time around because of Curiosity's advanced design. The wheels of Opportunity, Curiosity's predecessor, had basic, square holes, which allowed the rover to be bolted to its lander during cruise and touchdown. Since Curiosity didn't have a lander, though -- the thing, famously, pretty much landed itself -- JPL engineers suddenly had the freedom to create cleats in Curiosity's wheels that were aesthetic rather than pragmatic in function. And the Morse-to-Mars tribute to their work is what they chose. [link to www.nextgov.com] Last Edited by CE1 on 08/27/2012 11:46 PM |
