Curiosity Mars Rover Almost Complete

NASA's massive

'Curiosity' rover

is almost ready to begin the first leg of its long trek to the

surface of the Red Planet

. Engineers at

NASA's

Jet Propulsion Laboratory in California are nearly finished with assembling and testing all the components of the

Mars

Science Laboratory (MSL) mission (see photos above and below).

The MSL team plans to ship

Curiosity

as well as the cruise stage, descent stage and back shell to the

Kennedy Space Center

(KSC) in May and June. After arriving at KSC, all the pieces will be integrated together and tested during final assembly in a clean room. The

rover

will then be installed inside a 5 meter diameter nose cone, shipped the short distance to Cape Canaveral and then bolted atop an

Atlas V

rocket

(photo below).

The launch window for

Curiosity

extends from Nov. 25 to Dec. 18, 2011. The first stage of the

powerful

Atlas V

rocket will be augmented with four solid rocket boosters. The Atlas V has previously launched two planetary missions; the Mars Reconnaissance Orbiter (MRO) and the New Horizons mission to Pluto.

Take a long gander at the 3 meter long

rover

because its appearance is now very much how it will look while it's roving along

intriguing martian landscapes

for at least two earth years after landing in August 2012.

The mini-Cooper sized

Curiosity rover

is equipped with 10

science instruments

to

investigate Martian soil

and rock samples in far greater detail than ever before. Curiosity's science payload weighs ten times more than any prior

Mars rover

mission.

The goal is to search for clues to environmental conditions favorable for microbial life and for preserving evidence about whether

Martian life

ever existed in the past or today.

NASA

is scrutinizing a list of four potential landing sites for the best chance of finding a

habitable zone

.
