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.
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.
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.
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.
By combining the power of the Hubble Space Telescope, NASA’s Spitzer Space Telescope and one of nature’s zoom lenses, astronomers have found what is probably the most distant galaxy yet seen in the universe. The object offers a peek back into a time when the Universe was only 3% of its present age of 13.7 billion years.
A pinch of fine dust and sand from a patch of windblown material called “Rocknest” became the first sample of soil examined by the Mars Science Laboratory’s suite of laboratory instruments, called Sample Analysis at Mars. The sample was delivered on Nov. 9, allowing the mass spectrometry, gas chromatography, and laser spectrometry instruments to study the sample. Researchers are poring through the data now.
A California judge has tentatively ruled in favor of NASA's Jet Propulsion Laboratory in a wrongful termination lawsuit brought by a former computer specialist who alleged he was singled out in part because of his belief in intelligent design.
A set of instruments aboard the rover has ingested and analyzed samples of the atmosphere collected near the "Rocknest" site in Gale Crater where the Curiosity rover is stopped for research. With these initial sniffs of Martian atmosphere, preliminary results reveal little to no methane. Methane is of interest as a simple precursor chemical for life.
A new study based on data from European Space Agency’s Cluster mission shows that it is easier for the solar wind to penetrate Earth’s magnetic environment, the magnetosphere, than had previously been thought. Scientists have, for the first time, directly observed the presence of certain waves that show Earth’s atmosphere behaving more like a sieve than a barrier.
A new NASA study shows that from 1978 to 2010 the total extent of sea ice surrounding Antarctica in the Southern Ocean grew by roughly 6,600 square miles every year, an area larger than the state of Connecticut. However, this growth rate is not nearly as large as the decrease in the Arctic, which has scientists questioning the reasons for the growth. Atmospheric circulation may be one cause.
Southwest Research Institute (SwRI) has received funding from NASA to build a miniature, portable solar observatory for developing and testing innovative instrumentation in suborbital flight. The SwRI Solar Instrument Pointing Platform will fly on new, commercial manned suborbital craft to enable spaceborne science and instrument development at a fraction of the cost of unmanned sounding rockets.
An astronaut departing this week for the International Space Station said Monday that the bulk of the scientific benefits from the orbiting laboratory will be seen over the coming decade, amid questions on whether the estimated $100 billion spent in last 12 years is worth the effort. Portland, Indiana-born Kevin Ford said the station is just now entering the phase where the bulk of science being conducted there will come to fruition.
Predicted by Albert Einstein's general theory of relativity, the waves occur when massive celestial objects move and disrupt the fabric of space-time. But by the time these waves reach Earth, they are so weak that the planet expands and contracts less than an atom in response. No instrument or observatory has ever directly detected them. A pioneering technology capable of atomic-level precision is now being developed to detect what so far has remained imperceptible.
