Mars fascinates scientists because of its similarity to Earth, and it fascinates the public because our myth of "Martians" is a vision of life beyond Earth. The Mars【C1】______ continues with the launch of a robot vehicle by UK scientists. It’s part of a project to build an "autonomous robotic scientist" to【C2】______ the Martian surface and is key to the European Space Agency’s 2011 ExoMars【C3】______ .
The six-wheeled vehicle housing a myriad of scientific【C4】______ and detectors is the Mars rover, nicknamed "Bridget". Astrium, an EADS company, are【C5】______ the ExoMars rover prototype and coordinating its【C6】______ with other UK-based institutions.

Taking【C10】______ to twenty minutes for radio signals to reach Earth demands a powerful【C11】______ system to allow the rover to operate【C12】______ so they are also developing next generation computer software【C13】______ .
The rover will land on Mars packed to capacity【C14】______ scientific gadgets designed to be as light and as small as possible. The【C15】______ development time is essential for rigorous testing, as Waugh explains," 【C16】______ we put things in space we have to make sure that they’ll【C17】 ______ the radiation environment, the【C18】______ of heat and cold. Our science【C19】______ is crucial, and malfunctions may affect that. The more science we get back the betterC1【C20】______ there is for spending more money on planetary exploration." [br] 【C20】
