CAPE CANAVERAL, Fla. (Associated Press) - NASA launched a telescope Wednesday to scout out elusive, super high-energy gamma rays lurking in the universe. Glast - a NASA acronym standing for Gamma-ray Large Area Space Telescope - began its five- to 10-year Earth-orbiting mission with a midday blastoff aboard a Delta rocket.
The $690 million telescope, supported by six countries, will pick up where NASA's Compton Gamma Ray Observatory left off before its deliberate destruction in 2000, but in a bigger and better way.
With superior new technology and insight gained from Compton and other telescopes, Glast will be able to do in three hours, or two orbits of Earth - survey the entire sky - what Compton took 15 months to do. What's more, Glast and its particle detectors are much more sensitive and precise, and should provide an unprecedented view into the high-energy universe from a 345-mile-high orbit.

PODCAST & VIDEO: Engineering Around Extreme Events
Extreme events, such as super floods and hurricanes, are becoming more common, so civil engineers are trying to adapt civil infrastructure such as bridges to these unpredictable and sometimes devastating meteorological events. Engineer Ana Barros discusses how engineering can prepare us for extreme weather events, but also how changing climate and population conditions can affect the ability of infrastructure to hold up over time.
