CURIOSITY: Big Mars Rover for Big Mars Science! Artist’s Concept. NASA/JPL-Caltech
NASA’s Mars Rover Curiosity launched from Cape Canaveral in Florida. NASA/JPL-Caltech
Curiosity launched on an Atlas V-541, the largest rocket for launching to a planet. It is propelled toward Mars by a Centaur upper stage. Artist’s Concept. NASA/JPL-Caltech
Curiosity is headed to Gale Crater. You can see where other Mars landers and rovers have successfully landed on Mars too. NASA/JPL-Caltech
Gale Crater is about 96 miles wide. It has many rock layers for Curiosity to explore, from canyons to channels, all in one place! NASA/JPL-Caltech
Curiosity is targeted to land within the yellow ellipse, on flat terrain near Gale’s central mound. Central Mound NASAJPL-Caltech/ASU/UA
Curiosity is twice the size of Mars rovers Spirit and Opportunity and five times as heavy. NASA/JPL-Caltech
To fit all these tools on the rover, the team had to supersize everything, from the capsule that holds the rover, to the parachute that slows it down before landing. NASA/JPL-Caltech
To get to Mars, Curiosity will travel safely tucked inside a protective shell. Cruise Stage Back Shell Descent Stage Rover Heat Shield NASAJPL-Caltech
The trip will take over eight months.The rover will travel about 354 million miles (570 million kilometers). Artist’s Concept. NASA/JPL-Caltech

The spacecraft enters the Martian atmosphere 78 miles above the planet. The rover will take approximately seven minutes to reach the ground. Artist’s Concept. NASA/JPL-Caltech
This spacecraft can steer its way through the turbulent atmosphere so it can land more accurately. Artist’s Concept. NASA/JPL-Caltech
The friction of the atmosphere slows the spacecraft from 13,000 mph to about 900 mph. The heat shield may reach 3,800 degrees Fahrenheit! Artist’s Concept. NASA/JPL-Caltech
A supersonic parachute slows the spacecraft from about 900 mph to 180 mph, the speed of a Formula One race car. Artist’s Concept. NASA/JPL-Caltech
While slowing down using the parachute, the heat shield is popped off, exposing the rover to the Martian atmosphere. The rover’s descent camera begins taking a movie of the remaining five-mile flight to the ground. Artist’s Concept. NASA/JPL-Caltech
The engines on the descent stage roar to life and fly the rover down the last mile to the surface. As it descends, the rover uses radar to measure its speed and altitude, which it uses to land safely. Artist’s Concept. NASA/JPL-Caltech
The descent stage lowers the rover on three nylon ropes called bridle. Coiled electronics and communications cables also unspool from the descent stage. This configuration is known as the “Sky Crane.” Artist’s Concept. NASA/JPL-Caltech
By the time Curiosity touches down, the rover is going about two miles per hour. Less than seven minutes before, it was traveling at 13,000 miles per hour! Artist’s Concept. NASA/JPL-Caltech
When the sky crane “senses” that Curiosity has touched down, the cables are cut. The sky crane flies a safe distance away from the rover before crash-landing. Artist’s Concept. NASA/JPL-Caltech
For the first time, a Mars rover will land with wheels touching down first, instead of airbags. Artist’s Concept. NASA/JPL-Caltech
Curiosity will start exploring Mars after raising its “head” and doing a “self-check” to make sure all systems are go. Driving could take several days to a few weeks after landing. Artist’s Concept. NASA/JPL-Caltech
Curiosity is expected to work for one Martian year, or about two Earth years. Don’t miss the adventure on Mars, beginning August 2012! Artist’s Concept. NASAJ/PL-Caltech
