Go where no one has gone before—without leaving your computer. NASA has made more than 25,000 images of Mars available online at http://mars. jpl.nasa.gov/mgs/index.html. The images are from the Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) made during its mapping orbit, from March 1999 through August 1999. The Surveyor has made more than 5,000 orbits of the planet. The images include all of one Mars year, beginning in May 1997 and ending in September 1999, 687 Earth days.
As of May 2000, all MOC data acquired have been validated by the MGS MOC Operations Team at Malin Space Science Systems and deposited for permanent archive with the NASA Planetary Data System (PDS).
Also on the site are weekly reports of the project, live images of the command center, and VRML models of the spacecraft.
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
