This image was taken on a day when MAHLI and other instruments and tools on the turret were being inspected using the rover's Mastcams and Navcams.

The MAHLI cover was in the closed position in order to inspect the dust cover to ensure that the cover, its hinge, and the volume it sweeps when it opens are clear of debris.

Orion will be the most advanced spacecraft ever flown, and its parachutes have been designed with a return from exploration missions in mind.

The spacecraft will weigh more than 21,000 pounds as it descends through the air. Each of the main chutes only weighs 300 pounds, so it is quite a feat of engineering that they are able to catch the heavy weight of the spacecraft underneath them.

NASA has begun its latest hurricane science field campaign by flying an unmanned Global Hawk aircraft over Hurricane Leslie in the Atlantic Ocean during a day-long flight from California to Virginia. With the Hurricane and Severe Storm Sentinel (HS3) mission, NASA for the first time will be flying Global Hawks from the U.S. East Coast.

NASA's Aqua satellite flew over Tropical Storm Leslie on Sept. 5 during a picture perfect moment, just as it was being re-classified as a hurricane, and captured two images of the storm.

Leslie is forecast to pass east of Bermuda on Sunday, Sept. 9 as a hurricane.
