A half-century-plus after Sputnik, the swirling mass of operational spacecraft and space junk that has grown up around the planet is overwhelming mankind's ability to keep track of it, much less clean it up. Some of the world's biggest commercial satellite operators have teamed up to help each other with their space situational awareness (SSA), spurred by the 2009 collision between an active Iridium low-Earth-orbit (LEO) spacecraft and a defunct Russian military bird.

Boeing's Wideband Global Satcom began merely as a gapfiller project to provide communications for the U.S. military, but 11 years later the WGS satellites have become the backbone for shuttling the Pentagon's wideband data. And at a time when the Pentagon is planning to cut $487 billion over 10 years, WGS is being hailed as an example of an efficient satellite procurement.

China's new medium space launcher, the Long March 7, should fly late next year, entering service in an initial version capable of lifting 13.5 metric tons (30,000 lb.) to low Earth orbit, making it significantly larger than current Chinese rockets. The launcher will have four boosters, says Shen Lin, the principal engineer at manufacturer CALT, adding that China is also planning new upper stages.

Engineers say money is flowing for family of vehicles that will include a super-heavy launcher....

Planetary scientists in the U.S. and Europe are smarting from a $226.2 million cut in NASA's requested funding for robotic Mars exploration. That drives the final nail in the coffin of a joint Mars effort with the European Space Agency and obscures the future of Mars exploration in general.

The promise that high-bandwidth satellites can bring fast, cheap Internet to the masses will be put to the test in 2012 as a new generation of Ka-band spacecraft enters service in the U.S. and Europe, with plans to expand into Russia, Australia and Latin America.
