LOS ANGELES - NASA's next-generation rover to the surface of Mars, already over budget and behind schedule, may need more money to meet its November launch date, auditors have found.
The grim news was outlined in a report released Wednesday by NASA's inspector general.
Though project managers have solved most of the problems that caused the mission to be delayed by two years, auditors found significant hurdles remained before liftoff.
The mobile Mars Science Laboratory is intended to be the most sophisticated rover sent to the Martian surface. From the outset, the mission managed by the Jet Propulsion Laboratory has been plagued by development woes that have put it behind schedule and driven up costs. The price tag has ballooned to $2.5 billion from $1.6 billion.
