SUMMARY: The European Space Agency's Mars Express has relayed images from the NASA Mars rovers for the first time, demonstrating how the robots at Mars can work with each other to keep the data flowing back to Earth. Mars Express flew over the Opportunity rover on August 4, and received 15 images which were stored in the rover's memory. The data was transferred to the ESA's operations centre in Germany, and then passed along to NASA's JPL in Pasadena. This communication was possible because the rovers and Mars Express use the same communication protocols.
