REDONDO BEACH, Calif. -
A cool thing about space: cryogenic refrigerators from Northrop Grumman Corporation (NYSE:NOC) that chill satellite sensors to hundreds of degrees below zero Fahrenheit (°F) for maximum sensitivity.
A new NASA satellite with infrared sensors provides the most recent example. The space agency launched Orbiting Carbon Observatory-2 into space on July 2. Its mission is to make the clearest and most complete measurements ever of atmospheric carbon dioxide near the Earth's surface.
A chemical used in dry cleaning and fire extinguishers may have been phased out in recent years but NASA said Wednesday that carbon tetrachloride (CCl4) is still being spewed into the atmosphere from an unknown source.
The world agreed to stop using CC14 as part of the Vienna Convention on Protection of the Ozone Layer and its Montreal Protocol, which attained universal ratification in 2009.
"Parties to the Montreal Protocol reported zero new CCl4 emissions between 2007-2012,&quo...
LOGAN, Utah -
Utah State University's Space Dynamics Laboratory announced today that the U.S. Patent and Trademark Office has issued it a patent for a new invention by SDL research scientist Erik Syrstad .
Syrstad's invention, known as the Imaging Dispersive Energy Analyzer (IDEA), will allow next-generation measurements of the space environment from orbiting satellites.
"IDEA will sample gas and plasma particles in a region of space lying closest to Earth's atmosphere that is not ...
Lift-off for Galileo satellites 5 and 6 is set for Thursday, 21 August, at 12:31 GMT (14:31 CEST) on a Soyuz rocket from the Guiana Space Centre, French Guiana.
Just 9 minutes and 23 seconds later, the Fregat upper stage carrying the payload will separate from the Soyuz third stage, and conduct a pair of engine burns separated by an approximately three-hour ballistic coast phase.
Three hours and 47 minutes after launch, the Galileo satellites will separate into free-flight orbit, 23 5...
The Galileo satellites’ integration with Soyuz is shown in this series of photos, beginning with the upper composite’s transfer to the dedicated launch complex in French Guiana for this medium-lift launcher (left). At center, the upper composite is hoisted inside the mobile gantry, where it is integrated with Soyuz (right) to complete the launcher build-up for Arianespace’s Flight VS09.
