Operation of the High Energy Rocket Engine Research Facility (B-1), left, and Nuclear Rocket Dynamics and Control Facility (B-3) at the National Aeronautics and Space Administration’s (NASA) Plum Brook Station in Sandusky, Ohio. The test stands were constructed in the early 1960s to test full-scale liquid hydrogen fuel systems in simulated altitude conditions. Over the next decade each stand was used for two major series of liquid hydrogen rocket tests: the Nuclear Engine for Rocket Vehicle Application (NERVA) and the Centaur second-stage rocket program. The different components of these rocket engines could be studied under flight conditions and adjusted without having to fire the engine. Once the preliminary studies were complete, the entire engine could be fired in larger facilities. The test stands were vertical towers with cryogenic fuel and steam ejector systems. B-1 was 135 feet tall, and B-3 was 210 feet tall. Each test stand had several levels, a test section, and ground floor shop areas. The test stands relied on an array of support buildings to conduct their tests, including a control building, steam exhaust system, and fuel storage and pumping facilities. A large steam-powered altitude exhaust system reduced the pressure at the exhaust nozzle exit of each test stand. This allowed B-1 and B-3 to test turbopump performance in conditions that matched the altitudes of space.

The Nuclear Engine for Rocket Vehicle Applications (NERVA) was a joint NASA and Atomic Energy Commission (AEC) endeavor to develop a nuclear-powered rocket for both long-range missions to Mars and as a possible upper-stage for the Apollo Program. The early portion of the program consisted of basic reactor and fuel system research. This was followed by a series of Kiwi reactors built to test basic nuclear rocket principles in a non-flying nuclear engine. The next phase, NERVA, would create an entire flyable engine. The final phase of the program, called Reactor-In-Flight-Test, would be an actual launch test. The AEC was responsible for designing the nuclear reactor and overall engine. NASA Lewis was responsible for developing the liquid-hydrogen fuel system. The turbopump, which pumped the fuels from the storage tanks to the engine, was the primary tool for restarting the engine. The NERVA had to be able to restart in space on its own using a safe preprogrammed startup system. Lewis researchers endeavored to design and test this system. This non-nuclear Kiwi engine, seen here, was being prepared for tests at Lewis’ High Energy Rocket Engine Research Facility (B-1) located at Plum Brook Station. The tests were designed to start an unfueled Kiwi B-1-B reactor and its Aerojet Mark IX turbopump without any external power.

In the center foreground of this 1953 hangar photo is the YF-84A (NACA 134/Air Force 45-59490) used for vortex generator research. It arrived on November 28, 1949, and departed on April 21, 1954. Beside it is the third D-558-1 aircraft (NACA 142/Navy 37972). This aircraft was used for a total of 78 transonic research flights from April 1949 to June 1954. It replaced the second D-558-1, lost in the crash which killed Howard Lilly. Just visible on the left edge is the nose of the first D-558-2 (NACA 143/Navy 37973). Douglas turned the aircraft over to NACA on August 31, 1951, after the contractor had completed its initial test flights. NACA only made a single flight with the aircraft, on September 17, 1956, before the program was cancelled. In the center of the photo is the B-47A (NACA 150/Air Force 49-1900). The B-47 jet bomber, with its thin, swept-back wings, and six podded engines, represented the state of the art in aircraft design in the early 1950s. The aircraft undertook a number of research activities between May 1953 and its 78th and final research flight on November 22, 1957. The tests showed that the aircraft had a buffeting problem at speeds above Mach 0.8. Among the pilots who flew the B-47 were later X-15 pilots Joe Walker, A. Scott Crossfield, John B. McKay, and Neil A. Armstrong. On the right side of the B-47 is NACA's X-1 (Air Force 46-063). The second XS-1 aircraft built, it was fitted with a thicker wing than that on the first aircraft, which had exceeded Mach 1 on October 14, 1947. Flight research by NACA pilots indicated that this thicker wing produced 30 percent more drag at transonic speeds compared to the thinner wing on the first X-1. After a final flight on October 23, 1951, the aircraft was grounded due to the possibility of fatigue failure of the nitrogen spheres used to pressurize the fuel tanks. At the time of this photo, in 1953, the aircraft was in storage. In 1955, the aircraft was extensively modified, becoming the X-1E. In front o

Not one, but two nodosaurs passed through the Goddard campus 110 to 112 million years ago, a USGS paleontologist confirmed. Pictured here the second track, overlapping the first, looks to be a young version of the same creature, perhaps following and sniffing along after, said Rob Weems, emeritus paleontologist and stratigrapher with the USGS. “It’s definitely a track.” To read more go to: <a href="http://1.usa.gov/P9NYg7" rel="nofollow">1.usa.gov/P9NYg7</a> Credit: NASA/GSFC/Rebecca Roth <b><a href="http://www.nasa.gov/audience/formedia/features/MP_Photo_Guidelines.html" rel="nofollow">NASA image use policy.</a></b> <b><a href="http://www.nasa.gov/centers/goddard/home/index.html" rel="nofollow">NASA Goddard Space Flight Center</a></b> enables NASA’s mission through four scientific endeavors: Earth Science, Heliophysics, Solar System Exploration, and Astrophysics.

More than 9,000 years ago, a catastrophic volcanic eruption created a huge caldera on the southern end of Onekotan Island, one of the Kuril Islands, located off the southern tip of Russia’s Kamchatka Peninsula. Today, the ancient Tao-Rusyr Caldera is filled by the deep blue waters of Kal’tsevoe Lake. The Advanced Land Imager (ALI) on NASA’s Earth Observing-1 (EO-1) satellite acquired this true-color image of southern Onekotan on June 10, 2009. In this late-spring shot, snow or ice lingers on the land, forming white streaks on a brown-and-green land surface. In the northwest quadrant of the caldera is Krenitzyn Peak, which rises to a height of 1,325 meters (4,347 feet). Like the other Kuril Islands, Onekotan lies along the Pacific “Ring of Fire.” The Kuril Island volcanoes are fueled by magma generated by the subduction of the Pacific Plate under the Eurasian Plate, which takes place along a deep trench about 200 kilometers (120 miles) to the islands’ east. The only historical eruption at Krenitzyn Peak occurred in 1952, a week after a magnitude 9.0 earthquake along the subduction fault.

The islands and coral atolls of French Polynesia, located in the southern Pacific Ocean, epitomize the idea of tropical paradise: white sandy beaches, turquoise lagoons, and palm trees. Even from the distance of space, the view of these atolls is beautiful. This image from the Advanced Land Imager on NASA’s Earth Observing-1 (EO-1) satellite shows the southern part of Tikehau Atoll, one of the 78 coral atolls that make up the Tuamotu Archipelago. Patches of coral make star-like spots across the turquoise expanse of the lagoon. A line of tree-covered islets encircles the lagoon. At the southernmost tip of the atoll, a large islet accommodates a small village and an air strip. NASA image created by Jesse Allen, using EO-1 ALI data provided courtesy of the NASA EO-1 Team.
