Watch live: Northrop Grumman to launch NASA's ICON satellite

Science
Nov. 7 (UPI) -- Northrop Grumman will launch NASA's Ionospheric Connection Explorer satellite just after 3:00 a.m. EST on Wednesday aboard it's air-launched Pegasus XL rocket. Pegasus will be carried by and launch from Northrop Grumman's Stargazer L-1011 airplane from Cape Canaveral Air Force Station. The launch, which will be streamed live on NASA TV, carries the ICON satellite -- the 44th launch for Pegasus. NASA announced Tuesday that the weather forecast carries a 90 percent chance for favorable launch conditions. ICON will study the dynamic zone high in Earth's atmosphere where terrestrial weather meets space phenomena. The satellite will monitor the physics of near-Earth space and provide data for stopping its negative effects on technology and communications systems. ICON is based ...
Satellite data offers enhanced view of Earth's tectonic structures

Satellite data offers enhanced view of Earth's tectonic structures

Science
Nov. 5 (UPI) -- New satellite surveys and fresh gravity datasets are helping scientists image tectonic structures, revealing links between Antarctica and the rest of Earth's continents. Using data collected by the European Space Station's GOCE mission -- short for Gravity Field and Steady-State Ocean Circulation Explorer -- scientists have begun to identify the lithosphere structures that define the movement and evolution of the planet's continents. The insights made possible by the newly analyzed GOCE data offer a view of Earth's tectonics distinct from seismic surveys. Until now, detailed images of Antarctica's underlying tectonic structures have been hard to come by. By analyzing gradients in the gravity data collected by ESA's GOCE satellites, scientists were able to produce "curvatur...
Two Milky Way satellite galaxies collide

Two Milky Way satellite galaxies collide

Science
Oct. 26 (UPI) -- Two Milky Way satellite galaxies, Small Magellanic Cloud and the Large Magellanic Cloud, collided a few millions years ago, according to a new study by University of Michigan astronomers. Using new images collected by a powerful, orbiting telescope, University of Michigan astronomers noticed the southeast region, or "wing," of the Small Magellanic Cloud breaking off from its dwarf galaxy. Sally Oey, University of Michigan professor of astronomy, and undergraduate researcher Johnny Dorigo Jones worked with an international team of researchers to examine chunks of stars called "runaways" that had been ejected within SMC. This data came from Gaia, an orbiting telescope launched by the European Space Agency. "It's really interesting that Gaia obtained the proper motions of th...
ULA launches military comms satellite on Atlas V rocket

ULA launches military comms satellite on Atlas V rocket

Science
Oct. 16 (UPI) -- United Launch Alliance launched the fourth Advanced Extremely High Frequency satellite into space for the U.S. Air Force a little after midnight on Wednesday morning. AEHF-4 launched atop an Atlas V rocket from Cape Canaveral Air Force Station in Florida at 12:15 a.m. EDT. The rocket was rolled out to the launch pad Monday afternoon, preparing the 197-foot rocket for take-off. The Atlas V 551 variant was used for the launch, ULA said, which includes a kerosene-fueled common core booster and five solid rocket motors strapped on, as well as the Centaur upper stage and five-meter-diameter payload fairing. The first three AEHF satellites were launched in 2010, 2012 and 2013, with the system being declared at initial operational capability in 2015. The AEHF system is intended ...

Oct. 16 (UPI) -- If weather permits, United Launch Alliance will launch the fourth Advanced Extremely High Frequency satellite into space for the U.S. Air Force a little after midnight. AEHF-4 is scheduled to launch atop an Atlas V rocket early Wednesday morning from Cape Canaveral Air Force Station in Florida. The launch window opens at 12:15 a.m. EDT, with ULA giving the launch an 80 percent chance of happening on schedule.
