Ozone Suite On Suomi NPP Continues More Than 30 Years Of Ozone Data
2012-02-24 04:33:51

A new satellite instrument suite is now sending back detailed information about the health of the Earth's ozone layer, the shield that protects the world´s population from harmful levels of the sun's ultraviolet radiation. The Ozone Mapper and Profiler Suite, or OMPS, is one of five new instruments flying aboard NASA's Suomi National Polar-orbiting Partnership satellite (NPP), which was launched on Oct. 28, 2011. Suomi NPP is the result of a partnership between NASA, the National...

North America Safe From Impact Of Satellite

  NASA said on Friday that its Upper Atmosphere Research Satellite (UARS) will most likely miss North America. Scientists have still not pinpointed exactly where the 13,000-pound satellite is going to end up. The space agency said the odds of a piece of debris striking a person are about 1-in-3,200.  Scientists predict 26 pieces of debris will survive Earth's atmosphere, weighing a total of 1,100 pounds. UARS will re-enter Earth's atmosphere sometime Friday afternoon,...

Satellite Crashing Into Earth In T-Minus ???

  NASA said there is a 1-in-3,200 risk that a person who is minding their own business might find themselves being chased down by a defunct satellite the size of a tour bus traveling at 17,500-miles-per-hour. Of course, the odds of that exact scenario are higher, but the space agency did warn of the potential risk of being hit by falling debris from its Upper Atmosphere Research Satellite (UARS). According to estimates, the satellite will arrive back into Earth's atmosphere...

A new NASA study of Earth's polar ozone layer reinforces scientists' understanding of how human-produced chlorine chemicals involved in the destruction of ozone interact with each other. A team of scientists led by Michelle Santee of NASA's Jet Propulsion Laboratory, Pasadena, Calif., examined how nighttime temperatures affect chlorine monoxide, a key chemical involved in ozone destruction. Combining NASA satellite measurements with a state-of-the-art chemical model, they found this...

A NASA and university study of ozone and carbon monoxide pollution in Earth's atmosphere is providing unique insights into the sources of these pollutants and how they are transported around the world. For the first time, NASA and university researchers used simultaneous observations of carbon monoxide and ozone from space to differentiate between ozone produced from human activity and ozone produced from natural sources. Ozone is an important pollutant and a major component of smog. At high...

NASA -- Despite near-record levels of chemical ozone destruction in the Arctic this winter, observations from NASA's Aura spacecraft showed that other atmospheric processes restored ozone amounts to near average and stopped high levels of harmful ultraviolet radiation from reaching Earth's surface. Analyses from Aura's Microwave Limb Sounder indicated Arctic chemical ozone destruction this past winter peaked at near 50 percent in some regions of the stratosphere, a region of Earth's...

NASA -- Take a deep breath. On Earth the air is easy to take for granted. It's everywhere. But if you take a rocket into space the Earth's atmosphere falls away. Astronauts understand this at an instinctive level. Unlike just about every other career in the world, astronauts must bring their own atmosphere to work. It is this essential nature about the atmosphere that generated such high expectations for NASA's Aura satellite. Launched in July of 2004, this powerful research platform is...


Word of the Day
monteith
  • A large punch-bowl of the eighteenth century, usually of silver and with a movable rim, and decorated with flutings and a scalloped edge. It was also used for cooling and carrying wine-glasses.
  • A kind of cotton handkerchief having white spots on a colored ground, the spots being produced by a chemical which discharges the color.
This word is possibly named after Monteith (Monteigh), 'an eccentric 17th-century Scotsman who wore a cloak scalloped at the hem.'
