Nasa has selected 10 candidates for a low-cost Mars Scout mission that could be launched in 2007. Concepts include a martian atmospheric sample return mission, science orbiters, reconnaissance gliders, surface rovers and weather stations. Each should cost less than $300 million. The 10 will receive up to $150,000 funding for six months of continued study. NASA plans to initiate a competition to select a Scout mission next year.
