MAVEN is NASA’s next mission to Mars

NASA’s Mars Science Laboratory hasn’t even reached the red planet yet and NASA already has another Mars mission waiting in the wings, because that’s how it should be done. Just a barrage of awesome space missions. The next one is called MAVEN, the the Mars Atmosphere and Volatile Evolutio…N orbiter.

“MAVEN is just starting to come together in the clean room,” James Crocker, Lockheed Martin’s vice president and general manager for sensing and exploration systems, told reporters during a recent site tour here.

The large tank is more than 6 feet tall (1.83 meters), and is designed to hold 450 gallons of toxic hydrazine propellant.

Some of that fuel will be used to properly position the robotic spacecraft after it is captured into orbit around the Red Planet. With a technique called aerobraking, MAVEN will use the friction in Mars’ thin atmosphere to place itself in its so-called science orbit.

The MAVEN mission will be the first to investigate Mars’ upper atmosphere, in an attempt to understand what caused the Martian atmosphere to be lost into space. The spacecraft will also collect observations to help scientists piece together how this atmospheric loss has affected the planet’s climate over time. [7 Biggest Mysteries of Mars]

The $500 million mission is scheduled to launch in November 2013, and will reach Mars in 2014.

“MAVEN is trying to understand what happened to the atmosphere,” Crocker said. “Where did it go? It will help us understand how the gases in the atmosphere escape Mars.”

MAVEN will examine how much atmospheric gas is escaping into space, Lockheed Martin officials said. Once the current rate of atmospheric loss is determined, scientists can then use these figures to paint a picture of what occurred in the past.

These measurements will help researchers see how the Martian climate has become increasingly inhospitable to life, NASA officials have said.

So far, work on the MAVEN spacecraft has been on budget and on schedule, Lockheed Martin officials said. The spacecraft is expected to be delivered to NASA’s Kennedy Space Center in Cape Canaveral, Fla. next August.
