The International Space Station has a crew of six again, following launch and docking of Russia's Soyuz TMA-04M capsule with two cosmonauts and a NASA astronaut on board. The May 17 linkup restored the station to six-person operations for the first time since April 27, when a crew of three U.S. and Russian fliers descended to Earth after 5.5 months in orbit. Cosmonauts Gennady Padalka and Sergei Revin and NASA's Joseph Acaba (seen in this photo taken in the Russian space agency control room) lifted off from the Baikonur Cosmodrome in Kazakhstan on May 15.

Scientific and industrial research investments have yet to pay off.

Three Apollo commanders put their weight behind legislation that would force NASA to move quickly to choose a single commercial crew vehicle to elicit public support. Neil Armstrong, Eugene Cernan and James Lovell, commanders of Apollo 11, 17 and 13, respectively, told Rep. Frank Wolf (R-Va.), chairman of the House appropriations subcommittee that funds the space agency, that they endorse his panel's approach to commercial crew vehicle development that passed the House last week.

The big nuclear-powered Mars rover is NASA's last chance to drive scientific instruments around on the Martian surface in this decade.

As the U.S. looks for ways to reduce an immense budget deficit, planners in the military and intelligence communities appear to be questioning whether they really need two commercial imagery providers to supplement the super-capable government spacecraft. And that has set off a messy dance between two publicly traded satellite operators, DigitalGlobe and GeoEye, about whether they should merge and on what terms.

For most air travelers, access to high-speed Internet at 30,000 ft. is neither easy nor cheap. It's not that inflight broadband is unavailable to commercial and business jet passengers—a number of airlines are gradually adding connectivity options to their fleets. But despite the uptick in broadband-enabled tablets and smartphones in recent years, WiFi in the sky has been slow to gain traction in the broader airline community, where it can be sluggish, spotty and expensive.

Contenders for NASA's commercial crew program are revealing complete concepts and new teammates.

Congress and the White House are headed for a funding brawl over the expensive robotic spacecraft known as flagship planetary-science missions. Flagship missions are rare, because they cost $2-3 billion, and they may become rarer. In its spending request for fiscal 2013, NASA pulled back from work on a peer-reviewed flagship mission to return samples from the surface of Mars, and left it unclear if there will be any more flagship flights to explore elsewhere in the Solar System.
