Curiosity Mission in Pictures, Part 3: Launch Prepare & Take Off

On April 2004, the United States National Aeronautics and Space Administration (NASA) called for scientific experiments and instruments proposals for a planned Mars Science Laboratory rover mission. Launch was proposed for September 2009. Eight proposals were selected, including instruments from Russia and Spain. Testing of components also began in late 2004, including Aerojet's monopropellant engine with the ability to throttle from 15–100 percent thrust with a fixed propellant inlet pressure.


By November 2008 most hardware and software development was complete, and testing continued. At this point, cost overruns were approximately $400 million. On Decemer 2008, lift-off delayed to November 2011 due to insufficient time for testing and integration. Between March 23–29, 2009, the general public ranked nine finalist rover names (Adventure, Amelia, Journey, Perception, Pursuit, Sunrise, Vision, Wonder, and Curiosity) through a public poll on the NASA website. On May 27, 2009, the winning name was announced to be Curiosity. The name had been submitted in an essay contest by Clara Ma, a then sixth-grader from Kansas.

The blocks on the interior of the fairing are components of the fairing acoustic protection (FAP) system, designed to protect the payload by dampening the sound created by the rocket during liftoff. The two halves of the fairing will come together, protecting the spacecraft from the impact of aerodynamic pressure and heating during ascent. (NASA/Jim Grossmann).

(Right) On October 10, 2011, at NASA's Kennedy Space Center in Florida, the fairing acoustic protection (FAP) system lines the inside of the Atlas V payload fairing (the outer shell that will sit atop the rocket), for NASA's Mars Science Laboratory mission. This half of the fairing has been uncovered and laid on its side during preparations to clean it to meet NASA's planetary protection requirements. The FAP protects the payload by dampening the sound created by the rocket during liftoff. The fairing will protect the spacecraft from the impact of aerodynamic pressure and heating during ascent. Although jettisoned once the spacecraft is outside the Earth's atmosphere, the fairing must be cleaned to the same exacting standards as the laboratory to avoid the possibility of contaminating it.

(Up) A sequence of photos, showing the encapsulated spacecraft being lifted onto the rocket, you can see a dangling white hose attached toward the top of the fairing. That will also carry conditioned air, which will cool the spacecraft and also maintain positive air pressure inside the fairing, preventing microbes and contamination from Florida's moist air from reaching the spacecraft. NASA / Kim Shiflett.

(RightThe "Launch Vehicle" provides the velocity needed by a spacecraft to escape Earth's gravity and set it on its course for Mars. When mission planners are considering different launch vehicles, what they take into consideration is how much mass each launch vehicle can lift into space. A two-stage Atlas V-541 launch vehicle chosen to lift the Mars Science Laboratory spacecraft from Launch Complex 41 at Cape Canaveral Air Force Station, Fla. The vehicle was provided by United Launch Alliance, a joint venture of Boeing Co. and Lockheed Martin Corp.The Atlas V-541 vehicle was selected for the Mars Science Laboratory mission because it has the right liftoff capability for the heavy weight requirements and rockets in the same family have successfully lifted NASA's Mars Reconnaissance Orbiter and New Horizons missions.
Atlas V rockets are expendable launch vehicles (ELVs), which means they are only used once. The three numbers in the 541 designation signify a payload fairing, or nose cone, that is approximately 5 meters (16.4 feet) in diameter; four solid-rocket boosters fastened alongside the central common core booster; and a one-engine Centaur upper stage. The total length of the launch rocket was 191 feet (58 meters), the mass, fully fueled, with spacecraft on top was 1.17 million pounds (531,000 kilograms). Credit: NASA JPL.

The generator was lifted up to the top of the rocket and installed on the MSL spacecraft, encapsulated within the payload fairing. The MMRTG will generate the power needed for the mission from the natural decay of plutonium-238, a non-weapons-grade form of the radioisotope. (NASA/Dimitri Gerondidakis).

The fuel inside the LH2 (liquid hydrogen) tank is held at -420 F and requires insulation because the heat transfer rate is very high (large delta T across the tank wall to ambient temperature).
