New Materials Designed To Deal With Hypersonic And Supersonic Hot StuffBrisbane, Australia (SPX) Dec 28, 2009 University of Queensland researchers are testing new materials to withstand the extreme heat experienced by hypersonic vehicles in flight so they can fly for substantially longer. Previous Australian experimental flight tests of scramjets, a type of very fast jet engine, have not lasted longer than five seconds. The tests, conducted at Woomera in South Australia over the past eight years, have used scramjet engines made of conventional materials which have problems with extreme heat including melting, and are not designed for re-use. ... read more |

Washington (AFP) Dec 24, 2009Twitter not only wants to know what you're doing it wants to know where you are.

Washington (UPI) Dec 26, 2009 Three space missions in 2010 aim to learn more about the sun, and the climate and the oceans of Earth, NASA officials said. Two of the missions will examine the concentration of salt in oceans and the presence of aerosol particles, such as soot, in the atmosphere. "They are extraordinary timely," said Michael Freilich, head of NASA's Earth-science division, noting the results li ... more

Garching, Germany (SPX) Dec 28, 2009Using the NASA/ESA Hubble Space Telescope, astronomers have uncovered two distinct kinds of "rejuvenated" stars in the globular cluster Messier 30. A new study shows that both stellar collisions and a process sometimes called vampirism are behind this cosmic "face lift". The scientists also uncover evidence that both sorts of blue stragglers were produced during a critical dynamical event (known ... more 
Madison WI (SPX) Dec 28, 2009For almost 50 years, astronomers have puzzled over the youthful appearance of stars known as blue stragglers. Blue stragglers are the timeworn Hollywood starlets of the cosmos: They shine brightly, they are older than they appear, and they have, disconcertingly, gained mass at a late stage of life. "These blue, luminous stars should have used up their hydrogen fuel and flamed out long ago, ... more 
Guildford, UK (SPX) Dec 28, 2009Surrey Satellite Technology Ltd (SSTL) is today celebrating the 4th anniversary of the launch of its historic GIOVE-A satellite - the first step in Europe's visionary Galileo satellite navigation programme - on December 28th 2005. During the past 4 years, SSTL and GIOVE-A have contributed significantly to the testing and validation of technologies vital to the now imminent operational constellat ... more |
