Reader MojoKid sheds more light on NASA's unmanned cargo ship: The Orbital ATK CRS-6 mission that launched last week at NASA Cape Canaveral, Florida not only delivered supplies to the International Space Station (ISS), but also carried a number of research projects on NASA's Cygnus spacecraft. On board the CRS-6 were Gecko Grippers, which attempt to mimic the adhesion properties of gecko feet. Through the use of nanomaterials, Gecko Grippers can be repeatedly applied and removed from a surface without losing their adhesive properties via the use of van der Waals forces. They are also unaffected by temperature, pressure or radiation. Also in tow for the mission are supplies for the Saffire Experiment, which will be the largest man-made fire in space with data beamed back to earth so researchers can understand its properties and results. It's also impressive to see the NASA VAB (Vehicle Assembly Building), which is one of the biggest structures in the world covering 8 acres and measuring 525 ft tall, as well as the SLS Crawler, which is designed to move large spacecraft components supporting up to 18 million pounds and has been utilized for the Apollo and Space Shuttle programs.
