Who’s going the distance in the private sector space race

While Russia struggles to make up ground following a dozen-plus 2011 launch problems and the American Space Launch System sinks in Capitol Hill quicksand, the commercial space sector is racing to fill the gap — and to open new markets in space taxis, trucks and tourism. Since you can’t tell the players without a program, here are the . . .

Who doesn’t love a story about the little guy who makes it big, or the underdog that overcomes? Take these five mighty mites. What they lack in geographical size they make up for in strong economies and supersized space aspirations. As the new space race heats up, and as the airless reaches cease to be the sole province of superpowers, who knows how far their ambitions will carry them?

While Russian launches fail by the dozen, threatening operations aboard the International Space Station, and the American space program stalls amid political wrangling, China is building its own space laboratory, growing its satellite network, expanding its crewed space program, upgrading its launch facilities, improving its lift vehicles and laying the foundations for a moon shot. Are we witnessing the dawn of Chinese dominance in space?

On Aug. 6, 2012, a new rover will touch down on Mars — bigger, badder and bristling with more gear than a spelunker convention. Although rocking the same suspension system and basic design, Curiosity, aka the “monster truck of science,” is so much heftier than its predecessors that NASA and JPL had to invent an entirely new way to land it: one part HALO jump, one part rocket-hovering sky crane. Its mission: investigate if the right conditions exist, or ever have, to support microbial life.

NASA is planning its most powerful rocket to date, a jack-of-all-trades vehicle intended to carry the American space program through a dizzying array of potential  missions. Inheriting parts from the now-defunct space shuttle, its stillborn successor, Constellation, and the Saturn V workhorse that launched Americans to the moon, this modular monster is Senate-mandated to meet the requirements of any mission NASA dreams up, from  near-Earth milk runs to  massive undertakings like Mars exploration.

Can a single vehicle serve so many masters in so many ways, or will this phoenix turn out to be a turkey? Find out below – and then test your knowledge in the Big, Bad Space Launch System quiz.
