NASA and satellite company team up to explore asteroid

NASA and a Palo Alto-based satellite manufacturer are working to get a spacecraft to an asteroid before one gets to us. Asteroid exploration has become one of NASA's top goals, and Space Systems Loral will play a key role in an upcoming mission that will allow scientists to get research equipment to a unique asteroid to study its composition. It's the company's first major foray into the world of deep-space exploration.

Technique improves particle warnings and protect astronauts

Our sun sometimes erupts with bursts of light, solar material, or ultra-fast energised particles—collectively, these events contribute to space weather. In a study published in Space Weather, scientists from NASA and the National Center for Atmospheric Research, or NCAR, in Boulder, Colorado, have shown that the warning signs of one type of space weather event can be detected tens of minutes earlier than with current forecasting techni...

This is no fairy tale - TRAPPIST-1 and the seven planets

Once upon a time there lived, Snow White and the seven dwarfs. But now, NASA may have discovered the real-life version - TRAPPIST-1 and the seven planets. It turns out that life may have been discovered 39 light years away, as this week NASA has made the announcement that seven new earth size planets have been discovered. Previously scientists have only found a tiny number of ‘exoplanets’ which are believed to have the qualities ...

Researchers develop first image of a black hole

A team of researchers from around the world is getting ready to create what might be the first image of a black hole. The project is the result of collaboration between teams manning radio receivers around the world and a team at MIT that will assemble the data from the other teams and hopefully create an image. The project has been ongoing for approximately 20 years as project members have sought to piece together what has now become known ...

Lasers could give space research its 'broadband' moment

Thought your Internet speeds were slow? Try being a space scientist for a day. The vast distances involved will throttle data rates to a trickle. You're lucky if a spacecraft can send more than a few Mbps—a pittance even by dial-up standards. But we might be on the cusp of a change. Just as going from dial-up to broadband revolutionised the Internet and made high-resolution photos and streaming video a given, NASA may be ready to ...

NASA and MIT develop quantum-dot spectrometer

A NASA technologist has teamed with the inventor of a nanotechnology that could transform the way space scientists build spectrometers, the all-important device used by virtually all scientific disciplines to measure the properties of light emanating from astronomical objects, including Earth itself.

Chemistry method enhances search for life on other planets

A simple chemistry method could vastly enhance how scientists search for signs of life on other planets. The test uses a liquid-based technique known as capillary electrophoresis to separate a mixture of organic molecules into its components. It was designed specifically to analyse for amino acids, the structural building blocks of all life on Earth.

Communication system is next 'giant leap for mankind'

As with most scientific advancements, a stroke of brilliant genius usually revolutionises status quo and opens doors for new discoveries. Something similar happened to Keith Gendreau, an astrophysicist at NASA’s Goddard Space Flight Centre in Maryland. NASA was thinking of using X-rays on its proposed Black Hole Imager.

Astronauts upgrade station with latest batteries

Spacewalking astronauts hooked up batteries Friday on the International Space Station's sprawling power grid. NASA reported that all three lithium-ion batteries were up and running, a successful start to the space agency's long-term effort to upgrade the aging solar power system. Before venturing out, Commander Shane Kimbrough and Peggy Whitson got a hand from a robot that took care of most of the grunt work—Dextre, a hulking mach...

NASA supercomputer shows CO2 in the atmosphere

A NASA supercomputer project builds on the agency's satellite measurements of carbon dioxide and combines them with a sophisticated Earth system model to provide one of the most realistic views yet of how this critical greenhouse gas moves through the atmosphere. Scientists have tracked the rising concentration of heat-trapping carbon dioxide for decades using ground-based sensors in a few places.

Metallic glass gears make for graceful robots

At NASA's Jet Propulsion Laboratory in Pasadena, California, technologist Douglas Hofmann and his collaborators are building a better gear. Hofmann is the lead author of two recent papers on gears made from bulk metallic glass (BMG), a specially crafted alloy with properties that make it ideal for robotics. "Although BMGs have been explored for a long time, understanding how to design and implement them into structural hardware has proven el...

NASA Social focusses on advanced weather satellite mission

A NASA Social was one of several media events at NASA’s Kennedy Space Center focused on GOES-R - the first spacecraft in a series of NASA-built advanced geostationary weather satellites that will provide images of weather patterns and severe storms as regularly as every five minutes or as frequently as every 30 seconds.

NavCube supports X-ray communications demonstration in space

Two proven technologies have been combined to create a promising new technology that could meet future navigational challenges in deep space. It also may help demonstrate -- for the first time -- X-ray communications in space, a capability that would allow the transmission of gigabits per second throughout the solar system. The new technology, called NavCube, combines NASA's SpaceCube, a reconfigurable and fast flight computing platform, wit...

Ensuring you get your 5-a-day on Mars

Around this time of year the farmers down on earth will be planting away their crops ready for harvest, and so are the Astronauts up in space. In particularly the Astronauts aboard the International Space Station are planting their third on-orbit crop of red romaine lettuce. The Veg-03 experiment was initiated by NASA astronaut Shane Kimbrough, one of his first science assignments as a new crew member aboard the orbiting laboratory.

Possible water plumes erupted on Europa

Astronomers using NASA’s Hubble Space Telescope have imaged what may be water vapor plumes erupting off the surface of Jupiter’s moon Europa. This finding bolsters other Hubble observations suggesting the icy moon erupts with high-altitude water vapour plumes. The observation increases the possibility that missions to Europa may be able to sample Europa’s ocean without having to drill through miles of ice.
