Science on an Orbital Lab
The International Space Station, the orbiting laboratory which has logged over 1.5 billion statue miles—the equivalent of eight round trips to the Sun, is involved in a wide variety of experiments from biomedical work to microgravity research. Check out some of the incredible experiments the Expedition 38 crew are involved in.
Pictured: NASA astronaut Mike Hopkins, Expedition 38 flight engineer, holds a plastic container partially filled with green-colored water which will be used in a new experiment using the soccer-ball-sized, free-flying satellites known as Synchronized Position Hold, Engage, Reorient, Experimental Satellites, or SPHERES, which are already on the station. For the SPHERES-Slosh experiment, two SPHERES robots are attached to opposite ends of a metal frame holding the plastic tank with the green-colored water. The new hardware for the SPHERES-Slosh study was delivered to the station aboard Orbital Sciences' Cygnus cargo craft on Jan. 12, 2014.
