Lost to space

Once on location, MAVEN will undergo five and a half weeks of a "transition phase" to set up for the start of scientific work, Jakosky said.
Armed with science instruments, MAVEN is prepared to, among other investigations, find out how much of the atmosphere of Mars and volatiles have been lost to space over time. Studying the current state of the planet's upper atmosphere, ionosphere and interactions with the solar wind is also high on the agenda.
"It's the simultaneity of measurements that's really the key to the MAVEN analysis," Jakosky said. No doubt, there's lots oPutting on his astrobiological hat, Jakosky said that by assaying the processes through which the top of the Martian atmosphere can be lost to space, scientists could better understand the changes in the climate of Mars over the last 4 billion years. That, in turn, means MAVEN might deliver insight into whether microbes could have survived on Mars in the pastf room for surprise findings, he added.

The Mars Science Laboratory and its rover centerpiece, Curiosity, is the most ambitious Mars mission yet flown by NASA. The rover's primary mission is to find out if Mars is, or was, suitable for life. Another objective is to learn more about the red planet's environment.

Curiosity's extensive size allows it to carry a host of scientific experiments that will be able to zap, analyze and take pictures of any rock within reach of its 7-foot (2 meters) arm. Curiosity is about the size of a small SUV. It is 9 feet 10 inches long by 9 feet 1 inch wide (3 m by 2.8 m) and about 7 feet high (2.1 m). It weighs 2,000 pounds (900 kilograms). Curiosity's wheels have a 20-inch (50.8 cm) diameter.
