DARPA releases cause of hypersonic glider anomaly

April 22, 2012 1:46 pm | by John Antczak, Associated Press | News | Comments

Launched from an air base in California last summer, DARPA’s unmanned glider Hypersonic Technology Vehicle-2, achieve stable, controlled flight at speeds of Mach 20 for about three minutes before its flight system forced the craft into the ocean. The agency says it now knows the probable cause of the premature end to the flight.

Lunar Reconnaissance Orbiter brings “Earthrise” to everyone

April 20, 2012 7:20 am | News | Comments

On December 24, 1968, the astronauts aboard Apollo 8 were conducting an extensive photographic survey of the moon’s surface. When they paused to take a navigation sighting, they were shocked to see the Earth “rising” above the lunar surface. Using modern imagery, NASA’s Lunar Reconnaissance Orbiter has recreated the moment, shortly before the first real photograph was taken.

Particular attention was called to Small Business Innovation Research grant beneficiaries, some of whom shared their success stories at the briefing.

Nanosatellite makes first-ever measurements of auroral turbulence

March 22, 2012 7:24 am | News | Comments

The largest solar flare in the past five years triggered a major geomagnetic storm over Alaska on March 8. The same day, a nanosatellite operated by researchers from SRI International and the University of Michigan took a measurement of naturally occurring auroral turbulence. The data was the first-ever recorded using a nanosatellite radar receiver.

A biplane to break the sound barrier

March 19, 2012 4:32 am | by Jennifer Chu, MIT News Office | News | Comments

For 27 years, the Concorde provides its passengers with a rare luxury: time saved. However, on Nov. 26, 2003, the Concorde retired from service due to high fuel costs and noise disruption form the jet's sonic boom. Since then, a number of groups have been working on designs for the next generation of supersonic jets. A Massachusetts Institute of Technology researcher has come up with a concept that may solve many of the problems that grounded the Concorde.

Solid-rocket motor tests material for space launch system

March 18, 2012 7:27 pm | News | Comments

A sub-scale solid rocket motor designed to mimic NASA's Space Launch System, or SLS, booster design successfully was tested recently by engineers at NASA's Marshall Space Flight Center in Huntsville, Ala. The 20-second firing tested new insulation materials.

GM, NASA jointly developing robotic gloves for human use

March 14, 2012 6:27 am | News | Comments

General Motors (GM) and NASA are jointly developing a robotic glove that automotive workers and astronauts can wear to help do their respective jobs better while potentially reducing the risk of repetitive stress injuries.

A new approach to predicting spacecraft re-entry

March 12, 2012 4:12 am | News | Comments

In mid-December 2011, Lawrence Livermore National Laboratory received a call from the Air Force Joint Space Operations Center (JSpOC). At the time, laboratory scientists were working with JSpOC to upgrade their command and control software. But this call was about something very different.

President proposes national network for manufacturing innovation

March 10, 2012 6:49 am | News | Comments

After touring the Rolls-Royce Crosspointe jet engine disc manufacturing facility in Prince George, Va., on March 9, President Obama announced his intention to build a network of up to 15 manufacturing innovation institutes to serve as regional hubs of manufacturing excellence. The move is intended to make U.S. manufacturers more competitive and encourage investment.

Researchers seek cheaper, nimbler satellites

February 28, 2012 5:04 am | News | Comments

A new research program at Rensselaer Polytechnic Institute seeks to define the next generation of low-orbit satellites that are more maneuverable, cheaper to launch, easier to hide, and longer lived. Additionally, this research holds the promise of guiding dead satellites and other space debris more safely to the Earth's surface.

Mysterious electron acceleration explained

February 27, 2012 2:48 am | by David L. Chandler, MIT News Office | News | Comments

A mysterious phenomenon detected by space probes has finally been explained, thanks to a massive computer simulation that was able to precisely align with details of spacecraft observations. The finding could not only solve an astrophysical puzzle, but might also lead to a better ability to predict high-energy electron streams in space that could damage satellites.

When (and where) work disappears

February 24, 2012 7:11 am | by Peter Dizikes, MIT News Office | News | Comments

A new study from Massachusetts Institute of Technology shows that the rapid rise in low-wage manufacturing industries overseas has had a significant impact on the United States. The disappearance of U.S. manufacturing jobs frequently leaves workers unemployed for years, if not permanently, while creating a drag on local economies and raising the amount of taxpayer-borne social insurance necessary to keep workers and their families afloat.

Aircraft of the future could capture and re-use their own power

February 23, 2012 9:09 am | News | Comments

Tomorrow's aircraft could contribute to their power needs by harnessing energy from the wheel rotation of their landing gear to generate electricity. They could use this to power their taxiing to and from airport buildings, reducing the need to use their jet engines. This would save on aviation fuel, cut emissions, and reduce noise pollution at airports.
