The Canadian Space Agency is vying to contribute robotic expertise for NASA’s upcoming mission to Mars. Scientists want to satisfy their curiosity by looking for signs of life on the Red Planet. Since Viking first landed on the planet 25 years ago, American, Russian, Japanese and European missions have all tried to learn from Mars. “Mars is really the next big frontier to get to and the international community will go to Mars with or without Canada,” says Alain Berinstain of the Canadian Space Agency. “So it’s up to us to decide where this fits into our priorities.”
