Washington, D.C. – For more than three decades NASA has focused its space-faring skills and science chops CSI-like on an elusive global killer. Later this month, that pursuit takes us to East Asia. In a few years, part way to the moon.
We are getting close.
Air pollution causes an estimated 152,000 deaths a year across the Americas and more than 2 million deaths in the Western Pacific, according to the United Nations. Some parts of the world have a detailed view of local air quality from ground sensor networks and forecast models that generate public alerts. But for much of the world this type of information and warning are not available.

Pasadena, CA – Levels of “background ozone” — ozone pollution present in a region but not originating from local, human-produced sources — are high enough in Northern California and Nevada that they leave little room for local ozone production under proposed stricter U.S. ground-level ozone standards, finds a new NASA-led study.
The researchers, led by Min Huang of George Mason University, Fairfax, Virginia, used a novel technique that combined data acquired from two instruments on NASA’s Aura spacecraft in the summer of 2008.

Pasadena, CA – The LDSD launch support team is go to report to stations tonight at 9:00pm HST to begin preparations for a Monday, June 8th, 7:30am HST (1:30pm EDT) launch attempt from the U.S. Navy Pacific Missile Range Facility on Kauai, Hawaii.
NASA Television and JPL’s Ustream channel will carry live coverage of the launch beginning at 7:00am HST (1:00pm EDT).

Pasadena, CA – NASA scientists have identified an unexpected high-altitude methane ice cloud on Saturn’s moon Titan that is similar to exotic clouds found far above Earth’s poles.
This lofty cloud, imaged by NASA’s Cassini spacecraft, was part of the winter cap of condensation over Titan’s north pole. Now, eight years after spotting this mysterious bit of atmospheric fluff, researchers have determined that it contains methane ice, which produces a much denser cloud than the ethane ice previously identified there.

Pasadena, CA – The balloon launch occurred at 8:45am HST (11:45am PDT/3:45pm CDT) from the U.S. Navy’s Pacific Missile Range Facility in Kauai, Hawaii. At 11:05am HST (2:05pm PDT/6:05pm CDT), the test vehicle dropped away from the balloon (as planned), and powered flight began.
The balloon and test vehicle were about 120,000 feet over the Pacific Ocean at the time of the drop. The vehicle splashed down in the ocean at approximately 11:35am HST (2:35pm PDT/6:35pm CDT), after the engineering test flight concluded.

Pasadena, CA – A saucer-shaped vehicle designed to test interplanetary landing devices hangs on a tower in preparation for launch at the U.S. Navy’s Pacific Missile Range Facility in Kauai, Hawaii.
The saucer, which is part of NASA’s Low-Density Supersonic Decelerator (LDSD) project, will test two devices for landing heavy payloads on Mars: an inflatable tube and an enormous parachute.

Pasadena, CA – NASA’s Low-Density Supersonic Decelerator (LDSD) project, a rocket-powered, saucer-shaped test vehicle, has completed final assembly at the U.S. Navy’s Pacific Missile Range Facility in Kauai, Hawaii.
This experimental flight test is designed to investigate breakthrough technologies that will benefit future Mars missions, including those involving human exploration. Three weeks of testing, simulations and rehearsals are planned before the first launch opportunity on the morning of June 3rd. LDSD was built at NASA’s Jet Propulsion Laboratory, Pasadena, California, and shipped to Kauai for final assembly and preparations.

Pasadena, CA – New NASA research on natural ozone cycles suggests ozone levels in the lowest part of Earth’s atmosphere probably won’t be affected much by projected future strengthening of the circulating winds that transport ozone between Earth’s two lowest atmospheric layers.
The finding is good news, since human and plant health are harmed by exposure to ozone near the ground. Significant increases in ozone in Earth’s lowest atmospheric layer, the troposphere, would also lead to additional climate warming because ozone is a greenhouse gas.
NASA’s AIM spacecraft data shows Teleconnections in Earth’s Atmosphere linking Climate and Weather across the Globe

Washington, D.C. – Earth’s poles are separated by four oceans, six continents and more than 12,000 nautical miles.
Turns out, that’s not so far apart.
New data from NASA’s AIM spacecraft have revealed “teleconnections” in Earth’s atmosphere that stretch all the way from the North Pole to the South Pole and back again, linking weather and climate more closely than simple geography would suggest.

Mountain View, CA – NASA’s Global Hawk research aircraft returned to its base at NASA’s Armstrong Flight Research Center at Edwards Air Force Base, CA, early Friday morning March 14th, marking the completion of flights in support of this year’s Airborne Tropical Tropopause Experiment (ATTREX), a multi-year NASA airborne science campaign.
On February 13th, the autonomously operated aircraft began conducting science flights from Andersen Air Force Base on Guam in the western Pacific region on a mission to track changes in the upper atmosphere and help researchers understand how these changes affect Earth’s climate.
