The 3G-like capability that will eventually be available to warfighters from the U.S. Navy’s Mobile User Objective System (MUOS) is U.S.-only for now, but the spacecraft’s legacy UHF payload will remain available for allied use, according to U.S. Strategic Command. The Lockheed Martin-built MUOS satellites feature both the Wideband Code Division Multiple Access (WCDMA) payload and Boeing’s legacy UHF payload flying on the military’s existing Ultra High-Frequency Follow-On (UFO) satellites.

The 19-meter meteor that exploded over Chelyabinsk, Russia, was a fragment from a main-belt asteroid that broke up long ago and was too faint for detection by existing asteroid surveys, according to a new analysis of the Feb. 15 event.

FLOCKing BIRDS: An average of 115 satellites will be launched annually worldwide over the next 10 years (2013-2022), according to a new report from Euroconsult. “Revenues from the manufacture and launch of these 1,150 satellites over the decade will be worth $236 billion, up 26% from those generated by the 810 satellites launched in the past ten years (2003-2012),” Euroconsult says in a statement. Governments will be responsible for two-thirds of the 1,150 satellites to be launched and nearly three-quarters of the expected revenues.

CAMBRIDGE, Mass. — NASA astronaut Mike Hopkins started a series of on-orbit tests Monday that could lead to large “sparse arrays” of satellites in space maintaining their relative position using electromagnetic fields generated by superconducting coils.

Observations from Japan’s Suzaku X-ray astronomy satellite indicate that iron and other heavy elements that make life possible were spread throughout the universe during a violent period of stellar explosions and super-massive black hole outbursts 10 billion years ago. The findings come from a U.S.-Japanese research team that bases its conclusions on observations of the massive Perseus galaxy cluster.
