MH-60S Seahawk helicopters

ATLANTIC OCEAN (Aug. 6, 2012) MH-60S Seahawk helicopters assigned to the Golden Falcons of Helicopter Sea Combat Squadron (HSC) 12 fire flares during an air power demonstration above the Nimitz-class aircraft carrier USS Abraham Lincoln (CVN 72) during an air power demonstration. Lincoln is returning to the United States after the completion of an eight-month change-of-homeport deployment during which it operated in the U.S. 5th, 6th and 7th Fleet areas of responsibility.

Curiosity

This image is from a series of test images to calibrate the 34-millimeter Mast Camera on NASA's Curiosity rover. It was taken on Aug. 23, 2012 and looks south-southwest from the rover's landing site.

The gravelly area around Curiosity's landing site is visible in the foreground. Farther away, about a third of the way up from the bottom of the image, the terrain falls off into a depression (a swale). Beyond the swale, in the middle of the image, is the boulder-strewn, red-brown rim of a moderately-sized impact crater. Father off in the distance, there are dark dunes and then the layered rock at the base of Mount Sharp. Some haze obscures the view, but the top ridge, depicted in this image, is 10 miles (16.2 kilometers) away. 

Shuttles

CAPE CANAVERAL, Fla. – The space shuttle Endeavour, left, meets sister shuttle Atlantis for a brief photo opportunity at NASA's Kennedy Space Center in Florida. Endeavour moved from Bay 2 of the Orbiter Processing Facility OPF to switch places with Atlantis, which had been in Vehicle Assembly Building. In the OPF, Atlantis will undergo final preparations for its transfer to the Kennedy Space Center Visitor Complex, targeted for November. The work is part of Transition and Retirement of the remaining space shuttles, Atlantis and Endeavour. Atlantis is being prepared for public display at Kennedy's Visitor Complex. Over the course of its 26-year career, Atlantis spent 293 days in space during 33 missions. For more information, visit http://www.nasa.gov/transition Photo credit: NASA/Kim Shiflett

SACRAMENTO, Calif. (July 22, 2012) Lt. j.g. Daniel Glenn receives a baseball from a robot maneuvered by members of Explosive Ordnance Disposal Mobile Unit (EODMU) 3 before throwing out the ceremonial first pitch at Raley Field in Sacramento during Sacramento Navy Week. Sacramento Navy Week is one of 15 Navy weeks planned across America for 2012. Navy weeks are designed to show the investment Americans have made in their Navy and increase awareness in cities that do not have a significant Navy presence.

Curiosity's New Home

These are the first two full-resolution images of the Martian surface from the Navigation cameras on NASA's Curiosity rover, which are located on the rover's "head" or mast. The rim of Gale Crater can be seen in the distance beyond the pebbly ground. 

The topography of the rim is very mountainous due to erosion. The ground seen in the middle shows low-relief scarps and plains. The foreground shows two distinct zones of excavation likely carved out by blasts from the rover's descent stage thrusters.

Kennedy Space Center’s Shuttle Landing Facility

CAPE CANAVERAL, Fla. – This aerial view shows the north end of the Kennedy Space Center’s Shuttle Landing Facility. At the end of the runway, in the upper right, a rock and crater-filled planetary scape has been built so engineers can test the Autonomous Landing and Hazard Avoidance Technology, or ALHAT system on the Project Morpheus lander. Testing will demonstrate ALHAT’s ability to provide required navigation data negotiating the Morpheus lander away from risks during descent. Checkout of the prototype lander has been ongoing at NASA’s Johnson Space Center in Houston in preparation for its first free flight. The SLF site will provide the lander with the kind of field necessary for realistic testing. Project Morpheus is one of 20 small projects comprising the Advanced Exploration Systems, or AES, program in NASA’s Human Exploration and Operations Mission Directorate. AES projects pioneer new approaches for rapidly developing prototype systems, demonstrating key capabilities and validating operational concepts for future human missions beyond Earth orbit.

NASA's Morpheus lander

CAPE CANAVERAL, Fla. - At the north end of the Shuttle Landing Facility, or SLF, at the Kennedy Space Center in Florida, technicians check out NASA's Morpheus lander, a vertical test bed vehicle. A rock and crater-filled planetary scape, has been built so engineers can test the Autonomous Landing and Hazard Avoidance Technology, or ALHAT, system on the Project Morpheus lander. Checkout of the prototype lander has been ongoing at NASA’s Johnson Space Center in Houston in preparation for its first free flight. The SLF site will provide the lander with the kind of field necessary for realistic testing.

F-35

PATUXENT RIVER, Md. (June 27, 2012) Navy test pilot Lt. Christopher Tabert pilots the first external stores flight of the F-35C Lightning II Joint Strike Fighter test aircraft. The F-35C is distinct from the F-35A and F-35B variants with larger wing surfaces and reinforced landing gear for greater control when operating in the demanding carrier take-off and landing environment.
