Washington, D.C. "To detect life on Mars, we have to devise instruments to recognize it and design them in such a way to get them to the Red Planet most efficiently," said Dr. Andrew Steele of the Carnegie Institution's Geophysical Laboratory, a member of an international team designing devices and techniques to find life on Mars. "We've passed a major milestone. We successfully tested an integrated Mars life-detection strategy for the first time and showed that if life on Mars resembles life on Earth at all, we'll be able to find even a single-cell," he remarked.
