Study shows how to keep a Mars tumbleweed rover moving on rocky terrain
New research from North Carolina State University shows that a wind-driven "tumbleweed" Mars rover would be capable of moving across rocky Martian terrain - findings that could also help the National Aeronautics and Space Administration (NASA) design the best possible vehicle.

Return of the vacuum tube
Vacuum tubes have been retro for decades. They almost completely disappeared from the electronics scene when consumers exchanged their old cathode ray tube monitors for flat screen TVs. View More (2012-05-21)
You're beautiful, Vesta
When UCLA's Christopher T. Russell looks at the images of the protoplanet Vesta produced by NASA's Dawn mission, he talks about beauty as much as he talks about science. View More (2012-05-11)
IBEX Reveals a Missing Boundary At the Edge Of the Solar System
For the last few decades, space scientists have generally accepted that the bubble of gas and magnetic fields generated by the sun - known as the heliosphere - moves through space, creating three distinct boundary layers that culminate in an outermost bow shock. View More (2012-05-11)
TDRS-4 Mission Complete; Spacecraft Retired From Active Service
The Tracking and Data Relay Satellite 4 (TDRS-4) recently completed almost 23 years of operations support and successfully completed end-of-mission de-orbit and decommissioning activities. View More (2012-05-09)
Looking for Earths by looking for Jupiters
In the search for Earth-like planets, it is helpful to look for clues and patterns that can help scientist narrow down the types of systems where potentially habitable planets are likely to be discovered. View More (2012-05-08)
Science nugget: Lightning signature could help reveal the solar system's origins
Every second, lightning flashes some 50 times on Earth. Together these discharges coalesce and get stronger, creating electromagnetic waves circling around Earth, to create a beating pulse between the ground and the lower ionosphere, about 60 miles up in the atmosphere. View More (2012-05-04)
Report warns of rapid decline in US Earth observation capabilities; next-generation missions hindered by budget shortfalls, launch failures
A new National Research Council report says that budget shortfalls, cost-estimate growth, launch failures, and changes in mission design and scope have left U.S. earth observation systems in a more precarious position than they were five years ago. View More (2012-05-03)
Black Hole Caught Red-Handed in a Stellar Homicide
Astronomers have gathered the most direct evidence yet of a supermassive black hole shredding a star that wandered too close. NASA's Galaxy Evolution Explorer, a space-based observatory, and the Pan-STARRS1 telescope on the summit of Haleakala in Hawaii were among the first to help identify the stellar remains.

NASA's Chandra sees remarkable outburst from old black hole
An extraordinary outburst produced by a black hole in a nearby galaxy has provided direct evidence for a population of old, volatile stellar black holes. View More (2012-05-01)
Boron-Nitride Nanotubes Show Potential in Cancer Treatment
A new study has shown that adding boron-nitride nanotubes to the surface of cancer cells can double the effectiveness of Irreversible Electroporation, a minimally invasive treatment for soft tissue tumors in the liver, lung, prostate, head and neck, kidney and pancreas. View More (2012-04-27)
Warm Ocean Currents Cause Majority of Ice Loss from Antarctica
Warm ocean currents attacking the underside of ice shelves are the dominant cause of recent ice loss from Antarctica, a new study using measurements from NASA's Ice, Cloud, and land Elevation Satellite (ICESat) revealed. View More (2012-04-26)
Cassini sees new objects blazing trails in Saturn ring
Queen Mary scientists working with images from NASA's Cassini spacecraft have discovered strange half-mile-sized objects punching through parts of Saturn's F ring, leaving glittering trails behind them. View More (2012-04-25)
NASA's Lunar Reconnaissance Orbiter brings 'earthrise' to everyone
Imagine yourself in orbit, your spacecraft flying backward with its small window facing down toward the surface of the moon. You peer out, scouring the ash-colored contours of the cratered landscape for traces of ancient volcanic activity. View More (2012-04-20)
Webb Telescope spinoff technologies already seen in some industries
A critical component of the James Webb Space Telescope is its new technology. Much of the technology for the Webb had to be conceived, designed and built specifically to enable it to see farther back in time. View More (2012-04-19)
NASA satellite movie shows Great Plains tornado outbreak from space
Satellite data gives forecasters a leg up on severe weather. NASA has just released an animation of visible and infrared satellite data showing the development and movement of the Great Plains tornado outbreak, using data from NOAA's GOES-13 satellite. View More (2012-04-18)
Hubble's panoramic view of a turbulent star-making region
Several million young stars are vying for attention in a new NASA Hubble Space Telescope image of a raucous stellar breeding ground in 30 Doradus, a star-forming complex located in the heart of the Tarantula nebula. View More (2012-04-18)
Hubble's panoramic view of a turbulent star-making region
30 Doradus is the brightest star-forming region in our galactic neighbourhood and home to the most massive stars ever seen. The nebula resides 170 000 light-years away in the Large Magellanic Cloud, a small, satellite galaxy of our Milky Way. No known star-forming region in our galaxy is as large or as prolific as 30 Doradus. View More (2012-04-17)
Teamwork: IBEX and TWINS Observe a Solar Storm
On April 5, 2010, the sun spewed a two million-mile-per-hour stream of charged particles toward the invisible magnetic fields surrounding Earth, known as the magnetosphere. View More (2012-04-13)
