It's going to be a little while before humanity sets foot on Mars, but in the meantime NASA has a bundle of robots exploring the planet for us. The data they're collecting is valuable, but now researchers want to give their operators greater control. Specifically, they're interested in force feedback -- timely vibrations that would help astronauts carry out difficult tasks remotely. The European Space Agency (ESA) has developed a new rover with this in mind -- the "Interact Centaur," which has an onboard camera and two force-sensitive arms. ESA astronaut Andreas Mogensen is headed to the International Space Station (ISS) on September 2nd and, five days later, he'll be controlling one that's back on Earth.
