ULA launches 10th WGS comms satellite for U.S. military

Science
March 15 (UPI) -- United Launch Alliance launched a communications satellite for the United States Air Force on Friday evening at 8:26 p.m. EST. ULA's Delta IV rocket had a successful launch and jettisoned its liquid rocket motors on time as it entered the atmosphere. Just a few minutes after liftoff, the first and second stages separated. The rocket's second stage executed a series of engine burns to properly position the payload. After a technical glitch delayed proceedings, ULA released a new liftoff target of 7:52 p.m. Just minutes later, ULA announced a problem with NASA's Tracking and Data Relay Satellite System "will delay liftoff beyond our new ... launch time." The sun is rising over the #DeltaIV with #WGS10 on the launch pad this morning. Liftoff planned for today, March 15 at ...

Ten spacecraft have launched from California to complete the $ 3bn refurbishment of the original satellite phone system, Iridium. A SpaceX Falcon rocket carried the platforms aloft. They will go live in the network in the coming weeks.The original Iridium constellation was put up in the late 90s to link calls to any location on the planet. This function will continue, but the new satellites carry some add-ons to support additional services.One is monitoring technology to surveil the movements of planes.The UK's air traffic management company, NATS, and its Canadian equivalent, NAV CANADA, plan to use the new capability to transform the routing of aircraft across the North Atlantic.

Scientists use satellite images to measure household poverty

Scientists use satellite images to measure household poverty

Science
Jan. 7 (UPI) -- To more strategically allocate resources, set agenda priorities and track the progress of economic initiatives in the developing world, the United Nations is turning to satellite imagery. Researchers at Aarhus University in Denmark have developed methods for quantifying economic living conditions at the household level using high resolution satellite images. "Based on high-resolution satellite images, we can very precisely assess the status of poverty at household level in rural areas in developing countries," Jens-Christian Svenning, a professor and researcher at Aarhus, said in a news release. Using satellite images of portions of rural Kenya as a proof-of-concept test, scientists used several factors to estimate economic living conditions on local farms. Researchers ide...
ULA scrubs second spy satellite launch attempt 7 seconds before liftoff

ULA scrubs second spy satellite launch attempt 7 seconds before liftoff

Science
Dec. 8 (UPI) -- Another day, another scrub. United Launch Alliance once again called off the launch of its Delta 4-Heavy rocket, this time with just 7 seconds to go on the countdown. In an update, ULA said they called off the launch due to an "unexpected condition during terminal count." The mission delay marks the second scrubbed launch in as many days. The company's most powerful rocket was originally scheduled to carry a spy satellite into space on Friday, but a communications error forced ULA to delay the liftoff until Saturday evening. ULA hasn't yet announced when attempt three will take place. During Friday's preflight checks, engineers discovered a "redundant communication link between the control center and the launch site," according to a statement released by ULA. The rocket's...
