HOUSTON — President Obama’s proposed 2013 NASA budget of $17.771 billion, just $59 million below this year’s spending plan, has many at the agency’s Johnson Space Center in Houston relieved they were spared deep cuts. Yet there is a simmering concern of an imbalance between investments in commercial crew systems intended to ferry astronauts to low Earth orbit and the agency’s own Orion/Space Launch System for future deep-space destinations.

The FCC is indefinitely suspending LightSquared’s conditional waiver to operate its proposed 4G voice and data network in bands adjacent to those used by GPS, citing concerns that potential interference with GPS units could pose aviation safety risks. “The commission clearly stated from the outset that harmful interference to GPS would not be permitted,” the FCC says. “Consequently, the commission will not lift the prohibition on LightSquared.”

Risk reduction for the advanced strap-on boosters that will be needed to give NASA’s planned Space Launch System (SLS) the 130-metric-ton lift capability to low Earth orbit ordered by Congress will cost as much as $200 million over a 30-month period. The U.S. space agency on Feb. 14 released its expected NASA Research Announcement (NRA) for the advanced-booster risk mitigation, saying that it will make “multiple awards” for analysis and hardware demonstrations “and anticipates $200 million total funding.”

Faced with a cut in its fiscal 2013 aeronautics budget, NASA plans to reduce its hypersonics research, but maintain spending on technologies for subsonic and supersonic fixed- and rotary-wing aircraft. NASA is requesting $551.5 million for aeronautics research in 2013, down from $569.4 million in 2012. “The budget is very tight. We got $18 million less than we requested,” says Jaiwon Shin, associate administrator for aeronautics.

THE PENTAGON — The U.S. Missile Defense Agency’s fiscal 2013 funding request of $7.75 billion includes a major departure for the agency’s testing regime: shelving the massive Raytheon Sea-Based X-Band (SBX) radar. MDA has long used the radar, which is mounted on a large, floating platform, for providing targeting and discrimination data during flight tests in the Pacific region.

New programs to continue research into boost-glide hypersonic weapons for tactical and global precision strike are included in the U.S. Defense Advanced Research Projects Agency’s (Darpa) $2.82 billion budget request for fiscal 2013.

PARIS — Europe’s new Vega rocket lifted off like a streak from its launch pad at the Guiana Space Center in Kourou during a flawless Feb. 13 debut that carried nine satellites to orbit: the Lares laser relativity satellite, Italy’s Almasat-1 and seven cubesats developed by European universities.
