NASA's Aeronomy of Ice in the Mesosphere (AIM) satellite has captured five complete polar seasons of noctilucent (NLC) or "night-shining" clouds with an unprecedented horizontal resolution of 3 miles by 3 miles. Results show that the cloud season turns on and off like a "geophysical light bulb" and they reveal evidence that high altitude mesospheric "weather" may follow similar patterns as our ever-changing weather near the Earth's surface. These findings were unveiled Dec. 15 at the Fall...

The STPSat-1, built for the Department of Defense (DoD) Space Test Program (STP) and operated by the DoD STP for the first year then transitioned to NRL for the last 16 months, was decommissioned on October 7th after completing almost 2 ½ years of successful on-orbit operation. The satellite's two payloads, both designed and built by the Naval Research Laboratory (NRL), provided unique measurements of middle atmospheric hydroxyl, polar mesospheric clouds and the low...

A NASA rocket launched to study clouds spooked dozens of people along the U.S. East Coast, some worried about aliens landing, officials said. Exhaust particles from the rocket launched Saturday night at Wallops Flight Center in Virginia illuminated the sky with a cone-shape light that could be seen as far north as Massachusetts, NASA spokesman Keith Koehler said. CNN affiliate stations and NASA officials reported dozens of calls from people who saw the light, including some worried about...

WALLOPS ISLAND, Va., Sept. 9 /PRNewswire-USNewswire/ -- A rocket experiment that may shed light on the highest clouds in the Earth's atmosphere will be conducted Sept. 15 from NASA's Wallops Flight Facility in Virginia. (Logo: http://www.newscom.com/cgi-bin/prnh/20081007/38461LOGO) The Charged Aerosol Release Experiment (CARE) will be conducted by the Naval Research Laboratory and the Department of Defense Space Test Program using a NASA four-stage Black Brant XII suborbital sounding...

U.S. scientists say research involving the exhaust plume from a NASA space shuttle launch suggests the 1908 Tunguska explosion was caused by a comet The mysterious explosion leveled 830 square miles of Siberian forest and a cause has never been determined. But Cornell University researchers say findings from their study indicated the explosion was nearly certainly caused by a comet entering the Earth's atmosphere. It's almost like putting together a 100-year-old murder mystery, said Professor...

The mysterious 1908 Tunguska explosion that leveled 830 square miles of Siberian forest was almost certainly caused by a comet entering the Earth's atmosphere, says new Cornell University research. The conclusion is supported by an unlikely source: the exhaust plume from the NASA space shuttle launched a century later. The research, accepted for publication (June 24, 2009) by the journal Geophysical Research Letters, published by the American Geophysical Union, connects the two events by what...

The Naval Research Laboratory's Spatial Heterodyne Imager for Mesospheric Radicals (SHIMMER) has successfully observed a second northern season of Polar Mesospheric Clouds (PMCs), which are the Earth's highest clouds. This successful observation fulfills the primary goal of the Space Test Program Satellite-1 (STPSat-1) Extended Mission. SHIMMER was originally launched as the primary payload of STPSat-1 on March 8, 2007, with the objective to demonstrate the novel optical technique of Spatial...

When in space, keep an eye on the window. You never know what you might see.Last month, astronauts on board the International Space Station (ISS) witnessed a beautiful display of noctilucent or "night-shining" clouds. The station was located about 340 km over western Mongolia on July 22nd when the crew snapped this picture.Atmospheric scientist Gary Thomas of the University of Colorado has seen thousands of noctilucent cloud (NLC) photos, and he ranks this one among the best. "It's lovely,"...

Until now, Mars has generally been regarded as a desert world, where a visiting astronaut would be surprised to see clouds scudding across the orange sky. However, new results show that the arid planet possesses high-level clouds that are sufficiently dense to cast a shadow on the surface. The results were obtained by the OMEGA Visible and Infrared Mineralogical Mapping Spectrometer instrument on board ESA's Mars Express. Mars is not entirely a haven for Sun worshippers. Clouds of water ice...

barratry
  • The offense of persistently instigating lawsuits, typically groundless ones.
  • An unlawful breach of duty on the part of a ship's master or crew resulting in injury to the ship's owner.
