A new massive blimp-like aircraft was recently hovering just a dozen feet off a military hangar floor during flight testing south of Los Angeles. The fact that the hulking Aeroscraft could fly for just a few minutes represents a step forward in aviation, according to the engineers who developed it. According to the Department of Defense and NASA, their prototype could one day carry more cargo than any other aircraft to disaster zones and forward military bases.
Young engineers who weren't even born when the last Saturn V rocket took off for the moon are testing a vintage engine from the Apollo program. The engine, known to NASA engineers as No. F-6049, was grounded because of a glitch during a test in Mississippi and later sent to the Smithsonian Institution. Now, NASA engineers are using to get ideas on how to develop the next generation of rockets for future missions to the moon and beyond.
New information coming from researchers analyzing spectrometer data from NASA's Mars Reconnaissance Orbiter (MRO), which looked down on the floor of McLaughlin Crater on the Red Planet’s surface, suggests the formation of the carbonates and clay in a groundwater-fed lake within the closed basin of the crater. The depth of the crater may have helped allow the lake to form.
NASA is partnering with a commercial space company in a bid to replace the cumbersome "metal cans" that now serve as astronauts' homes in space with inflatable bounce-house-like habitats that can be deployed on the cheap. A $17.8 million test project will send to the International Space Station an inflatable room that can be compressed into a 7-foot tube for delivery.
Engineers working on NASA's James Webb Space Telescope have recently concluded performance testing on the observatory's aft-optics subsystem at Ball Aerospace & Technologies Corp's facilities in Boulder, Colo. This is significant because it means all of the telescope's mirror systems are ready for integration and testing.
NASA scientists and engineers are working now to lay the groundwork for the Aerosol-Cloud-Ecosystem (ACE) mission, which will change what we can learn about clouds and aerosols. To that end, the Polarimeter Definition Experiment (PODEX) in Southern California will soon commence, testing a new class of polarimeters that are especially suited for finding the type, shape, and size of particles in the upper atmosphere.
About nine years ago, when astronomers first saw Apophis, they thought there was a 2.7% chance that it would smack into our planet. Later, they lowered the chances to an even more unlikely 1 in 250,000. Now it's never mind, they say, as the 1,060-foot wide rock will approach to within 20,000 miles.
The quest for a twin Earth is heating up. Using NASA's Kepler spacecraft, astronomers are beginning to find Earth-sized planets orbiting distant stars. A new analysis of Kepler data shows that about 17% of stars have an Earth-sized planet in an orbit closer than Mercury.
After imaging during the holidays, NASA's Mars rover Curiosity resumed driving Jan. 3 and pulled within arm's reach of a sinuous rock feature called "Snake River." Snake River is a thin curving line of darker rock cutting through flatter rocks and jutting above sand. Curiosity's science team plans to get a closer look at it before proceeding to other nearby rocks.
In the past week, researchers with the West Antarctic Ice Sheet Divide (WAIS) project, the Whillans Ice Stream Subglacial Access Research Drilling (WISSARD) project and the Pine Island Glacier (PIG) project each announced they had achieved these various milestones. In each case, the successes were based on innovative drilling technologies and promise to open new scientific vistas for Antarctic research.
Just in time for the holidays, NASA's Cassini spacecraft, in orbit around Saturn for more than eight years now, has delivered another glorious, backlit view of the planet Saturn and its rings.On Oct. 17, 2012, during its 174th orbit around the gas giant, Cassini was deliberately positioned within Saturn's shadow, a perfect location from which to look in the direction of the sun and take a backlit view of the rings and the dark side of the planet.
A new study indicates that clay minerals, rocks that usually form when water is present for long periods of time, cover a larger portion of Mars than previously thought. In fact, the research team say clays were in some of the rocks studied by Opportunity when it landed at Eagle crater in 2004. But Opportunity doesn’t have the capability any longer to detect these clays, which were found using spectroscopic analysis from the Mars Reconnaissance Observer.
Meteorites that had fallen from an asteroid impact that lit up the skies over California and Nevada in April were quickly recovered by scientists and recent studies report that this space rock is an unusual example from a rare group known as carbonaceous chondrites, which contain some of the oldest material in the solar system. It is also complex, containing molecules such as water and amino acids.
The Mars Science Laboratory is more than the biggest rolling science laboratory ever put on another planet. It's a systems engineering—and product development—triumph.
Changes in the R&D environment are driving research managers to look at different ways to support and grow their organizations.
On Friday, engineers are turning off the science instruments in preparation for Monday's big finale. After nearly a year circling the moon, NASA's Ebb and Flow will meet their demise when they crash—on purpose—into the lunar surface. Just don't expect to see celestial fireworks as it will happen on the dark side of the moon.
A galaxy that was once thought to be the oldest known has regained its lost title after a record-long series of exposures by the Hubble Space Telescope revealed that it is in fact 13.3 billion years old, 100 million years older than previously thought. The study, which looked back to when the universe was just 4% of its present age, found six other similarly ancient galaxies.
The military's small, top-secret version of the space shuttle rocketed into orbit Tuesday for a repeat mystery mission, two years after making the first flight of its kind. The X-37B is about one-quarter the size of the original NASA space shuttle and can land automatically. The purpose of this mission remains a secret: Launch commentary ended 17 minutes into the flight.
A new NASA-funded prototype system developed by the National Center for Atmospheric Research now is providing weather forecasts that can help flights avoid major storms as they travel over remote ocean regions. The eight-hour forecasts of potentially dangerous atmospheric conditions are designed for pilots, air traffic controllers and others involved in transoceanic flights.
Eugene A. Cernan, a Purdue University alumnus and the most recent person to walk on the moon, stepped out of the lunar lander 40 years ago Tuesday. Commander of Apollo 17, Cernan made three moonwalks, explored the barren landscape in a lunar rover, collected about 250 pounds of soil samples and moon rocks, and took scientific measurements.
Results presented Wednesday at the meeting of the American Geophysical Union meeting in San Francisco show that the moon took a beating in its early days, far more than previously believed. Detailed gravity mapping by NASA’s Ebb and Flow spacecraft show the extent to which the moon was broken up and shattered from bombardment by asteroids and comets.
NASA's Van Allen Probes have been exploring the hostile radiation belts surrounding Earth for just three months. But already measurements in unprecedented detail have been taken. Scientists said Tuesday these waves can provide an energy boost to radiation belt particles, somewhat like ocean waves can propel a surfer on Earth. What's more, these so-called chorus waves operate in the same frequency as human hearing so they can be heard.
The space agency on Tuesday announced plans to launch another mega-rover to the red planet in 2020 that will be modeled after the wildly popular Curiosity. To keep costs down, engineers will borrow Curiosity's blueprints, recycle spare parts where possible and use proven technology including the novel landing gear that delivered the car-size rover inside an ancient crater in August.
A jet of X-rays from a supermassive black hole 12.4 billion light years from Earth has been detected by NASA’s Chandra X-ray Observatory. This is the most distant X-ray jet ever observed and gives astronomers a glimpse into the explosive activity associated with the growth of supermassive black holes in the early universe.
A team of researchers have built a new type of nuclear reactor that is reliable enough to be used on space flights. The prototype, which has been used to generate 24 W of electricity, relies on heat pipe technology developed at Los Alamos National Laboratory in 1983. The fluid-based cooling system requires no moving parts and the reactor itself is based on a simply closed-loop Stirling engine.
