VideoAstronauts return to US side of space station after leak scare
Concern about a possible ammonia coolant leak Wednesday prompted astronauts on the International Space Station to evacuate the U.S. segment of the complex and shelter in the Russian portion of the outpost while flight controllers scrambled to untangle initially confusing telemetry.
SpaceX launch scrubbed by steering system problem
Launch of a SpaceX Falcon 9 rocket carrying a Dragon cargo ship loaded with more than 5,100 pounds of equipment and supplies bound for the International Space Station was called off Tuesday less than two minutes before liftoff because of apparent problems with the second stage engine steering system.
Kelly, Kornienko eager for launch on one-year mission
NASA astronaut Scott Kelly and Russian cosmonaut Mikhail Kornienko are gearing up for launch March 27 to kick off a record one-year stay aboard the International Space Station, an orbital marathon both men say is crucial for planning future flights beyond Earth orbit and, eventually, to Mars.
International crew set for launch to space station Sunday
Soyuz TMA-15M commander Anton Shkaplerov, flanked on the left by flight engineer Samantha Cristoforetti and on the right by NASA astronaut Terry Virts, are scheduled for liftoff from complex 31 at the Baikonur Cosmodrome in Kazakhstan on Sunday.
VideoSoyuz lands in Kazakhstan with station crew
A veteran cosmonaut, a German volcanologist and a Navy test pilot-turned-astronaut undocked from the International Space Station and returned to Earth, descending through low clouds to a jarring touchdown on the frigid steppe of Kazakhstan to close out a 165-day stay in orbit.
Station trio set for return to Earth
A veteran cosmonaut, a German volcanologist and a Navy test pilot-turned-astronaut whose mastery of social media earned him -- and NASA -- a global following, bid their space station crewmates farewell and sealed the hatch of their Soyuz ferry craft, setting the stage for undocking and a fiery trip back to Earth to close out a 165-day stay aboard the International Space Station.
Station astronaut calls private spaceflight ‘next breakthrough’
Space station astronaut Reid Wiseman, preparing to return to Earth this weekend after 165 days in orbit, said commercial spaceflight represents the "next breakthrough" in aerospace technology, and that he hopes Virgin Galactic can ultimately turn that dream into reality despite the fatal crash of the company's SpaceShipTwo rocket plane.
Orbital Sciences rocket, station cargo ship, lost in spectacular launch mishap
An Orbital Sciences Antares rocket exploded seconds after launch from the Virginia coast Tuesday, erupting in a spectacular fireball and destroying the company's third operational Cygnus cargo ship in a disheartening failure for NASA's commercial space station resupply program.
Russian cosmonauts wrap up successful spacewalk
Two cosmonauts ventured outside the International Space Station, jettisoning three no-longer-needed components and carrying out a photo survey of the Russian segment of the lab complex in the seventh and final spacewalk planned by the station crew this year.
Spacewalk achieves all major objectives
Astronauts Reid Wiseman and Barry "Butch" Wilmore floated outside the International Space Station and, after a bit of trouble with a balky bolt, replaced a broken voltage regulator in one of eight solar power channels to restore the lab's electrical grid to normal operation.
