NASA/United Launch Alliance
Mars Phoenix is currently being prepared to land on the Red Planet in 2008. The Phoenix will be used to study the soil in the northern arctic region of Mars.
The rovers are caught in the worst storms scientists have ever seen on Mars. Swirling dust threatens to cover the solar panels on the long-running Mars rovers, choking off their energy supply. Also, guests discuss a new Mars mission, Mars Phoenix, set to launch next week.
