The rover for NASA's Mars Science Laboratory mission, named Curiosity, is about 3 meters (10 feet) long, not counting the additional length that the rover's arm can be extended forward. The front of the rover is on the left in this side view. The arm is partially raised but not extended. Rising from the rover deck just behind the front wheels is the remote sensing mast.

Curiosity Mars Rover Almost Complete

8 Apr , 2011 by


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.

My head would’a split wide open if I’d’a seen this when I was 10, back in ’76. My Zod, how far it’s come…

What an exciting mix of instruments! Good to see Atlas V’s track record, too.
Too bad we couldn’t build two like this!
