NASA Landing nuclear powered rover on Mars using a Sky Crane
Mars Science Laboratory represents the first use of a "soft-landing" technique employed at Mars.
The sheer mass of Mars Science Laboratory prevents engineers from using
the familiar airbags to deliver their rover safely to the martian
surface. As rovers become more capable and carry more instruments, they
become larger. So, in order to accommodate this advanced mission,
engineers designed a sky-crane method that will lower the rover to the
surface. The Mars science lab mission landing will be in 3.5 days. (5:31
am UTC August 6, 2012).
