NORUSCA II Camera Examines Auroras
2012-11-29 19:36:55

Lee Rannals for redOrbit.com — Your Universe Online Space-weather researchers joined forces to design and build NORUSCA II in order to help expand the understanding of auroras and other atmospheric events. NORUSCA II is a new camera with the capabilities of simultaneously imaging multiple spectral bands. The camera was tested at the Kjell Henriksen Observatory (KHO) in Svalbard, Norway. The camera produced the first-ever hyper spectral images of auroras and may have already...

Cassini Shows Titan Glow In The Dark On Halloween
2012-11-01 06:21:22

NASA/Jet Propulsion Laboratory A literal shot in the dark by imaging cameras on NASA's Cassini spacecraft has yielded an image of a visible glow from Titan, emanating not just from the top of Titan's atmosphere, but also - surprisingly - from deep in the atmosphere through the moon's haze. A person in a balloon in Titan's haze layer wouldn't see the glow because it's too faint - something like a millionth of a watt. Scientists were able to detect it with Cassini because the spacecraft's...

By Kim Gudeman, University of Illinois Researchers at the University of Illinois have become the first to record an airglow signature in the upper atmosphere produced by a tsunami using a camera system based in Maui, Hawaii. The signature, caused by the March 11 earthquake that devastated Japan, was observed in an airglow layer 250 kilometers above the earth's surface. It preceded the tsunami by one hour, suggesting that the technology could be used as an early-warning system in the future....

Data products from the Special Sensor Ultraviolet Limb Imager (SSULI) developed by the NRL Spacecraft Engineering Department and Space Science Division were officially transitioned for use in operational systems at the Air Force Weather Agency (AFWA) on June 9, 2011. After extensive validation of the SSULI sensor software and derived atmospheric specification, the Air Force Weather Agency received a formal letter from the Defense Weather Systems Directorate (DWSD) at the Air Force Space and...

The Special Sensor Ultraviolet Limb Imager (SSULI) developed by NRL's Spacecraft Engineering Department and Space Science Division, launched October 18, 2009 on the U.S. Air Force Defense Meteorological Satellite Program (DMSP) F18 (flight 18) satellite, observed first light on December 1, 2009. In a sample airglow profile the spectral emission features in the data are clean and show no anomalies. "The SSULI team is very excited to continue with early orbit testing and begin the calibration...

Launched from Vandenberg Air Force Base, Calif., aboard an United Launch Alliance Atlas V launch vehicle, Oct. 18, 2009, the Special Sensor Ultraviolet Limb Imager (SSULI) developed by NRL's Space Science Division and Spacecraft Engineering Department offers a first of its kind technique for remote sensing of the ionosphere and thermosphere from space. Flying on-orbit the U.S. Air Force Defense Meteorological Satellite Program (DMSP) F18 (flight 18) satellite, SSULI's characterization of the...

The Indian launcher Polar Space Launch Vehicle took off at 8:22 a.m. - Swiss time. Twenty minutes later, the SwissCube was ejected from the nose cone of the rocket at an altitude of around 720 kilometers. At 9:37 a.m. the first ever signals sent from a Swiss satellite in space were picked up from Stanford (California). Mission accomplished. Students and professors have been working very hard during the last three and a half years in order to send the concentrated cube of high technology into...

ESA's Venus Express spacecraft has observed an eerie glow in the night-time atmosphere of Venus. This infrared light comes from nitric oxide and is showing scientists that the atmosphere of Earth's nearest neighbor is a temperamental place of high winds and turbulence. Unfortunately, the glow on Venus cannot be seen with the naked eye because it occurs at the invisible wavelengths of infrared. ESA's Venus Express, however, is equipped with the Visible and Infrared Thermal Imaging Spectrometer...

Data from Venus Express, which has been revealing new and crucial details about our closest planetary neighbour, will now be augmented by synoptic data from a coordinated ground-based observation campaign. This campaign will contribute to the growing body of information on the nature of Venus's atmosphere and will help put the spacecraft's observations into a broader context. Between 23 May and 9 June, scientists working at a dozen telescopes and observatories spread all over the world will...

One year has passed since April 11, 2006, when Venus Express, Europe's first mission to Venus and the only spacecraft now in orbit around the planet, reached its destination. Since then, this advanced probe, born to explore one of the most mysterious planetary bodies in the Solar System, has been revealing planetary details never caught before. Intensively visited by several Russian and American probes from the 60s to the early 90s, Venus has always represented a puzzling target for...
