title: Mars exploration. Plan for two rovers squeezes NASA budget.
abstract: NASA's decision last week to send two rovers to Mars in 2003 is being hailed by researchers as affirming the agency's commitment to exploring the Red Planet. But once the applause dies down, cash-strapped space science managers will be forced to make tough decisions about how to shoulder the added $200 million cost of a second mission, starting with $96 million that must come out of NASA's 2001 budget.
