LRO Shows Ice May Make Up As Much As 22 Percent Of Shackleton Crater Floor
NASA's Lunar Reconnaissance Orbiter (LRO) spacecraft has returned data that indicate ice may make up as much as 22 percent of the surface material in a crater located on the moon's south pole. The team of NASA and university scientists using laser light from LRO's laser altimeter examined the floor of Shackleton crater.
Trials Will Include First Autonomous, Vision-Based Weather-Avoidance Routing
A Jetstream aircraft known as ‘The Flying Test Bed’, which can fly as if it were a UAV, is undergoing a series of flight trials in preparation for the first maiden flight of a surrogate UAV in UK shared airspace later this year.
Brazilian Planemaker Now Has Chinese Orders For 159 Commercial And Executive Jets
A deal for 10 Legacy 650 executive jets, consisting of five firm orders and five options, has been signed between ICBC Financial Leasing Co. and Harbin Embraer Aircraft Industry Co., Embraer’s joint-venture with Aviation Industry Corporation of China (AVIC).

Highly skilled Civil Air Patrol cadets from across America have gathered in Dayton, Ohio, this week for the 2012 National Cadet Competition, a prestigious CAP inspection and drill event that originated in 1947.
Honor Bestowed By The John Glenn School Of Public Affairs
NASA Administrator Charles Bolden was presented the Excellence in Public Service Award Thursday by former Senator and astronaut John Glenn on behalf of the John Glenn School of Public Affairs at The Ohio State University.
Las Vegas Police Helicopter Rotors Touched A Wall In Red Rock Canyon
A Bell HH-1H "Huey" helicopter operated by the Las Vegas police was on a training mission May 18th when a gust of wind pushed it too close to the walls of Red Rock Canyon, causing the main rotor blades to touch the rockface. The pilots landed the aircraft safely with no injuries to any of the five people on board.
Aero Linx: Michigan Business Aviation Association (MBAA)
The Michigan Business Aviation Association (MBAA) was founded in 1998 and represents businesses and individuals with a common interest of working towards the preservation and development of an air transportation system including an airport infrastructure and other aviation issues affecting the State of Michigan. The Association is dedicated to the promotion and advocacy of the importance of business air travel to the state’s economy and the importance of sufficient funding to preserve, develop and assure safety at Michigan airports. The Association recognizes the need to improve the understanding and importance of aviation by state and local officials. The
A small motion in the Earth's rotation axis relative to the surface, discovered by American astronomer Seth Carlo Chandler in 1891. Its amplitude is about 0.7 arcseconds (about 15 meters on the surface) with a period of 433 days. It combines with another wobble with a period of one year, so the total polar motion varies with a period of about 7 years. The Chandler wobble is an example of free nutation for a spinning non-spherical object.
"The brightness measurements have been puzzling us since two summers ago... While the distribution of brightness was not exactly what we had expected, practically every measurement related to ice and other volatile compounds on the moon is surprising, given the cosmically cold temperatures inside its polar craters."
