Koch and crewmates back on Earth
Christina Koch, veteran of six spacewalks outside the International Space Station -- including the first all-female excursion -- joined a Russian commander and an Italian flight engineer for a fiery plunge to landing in frigid Kazakhstan early Thursday, setting a new record for the longest single flight by a female.
Koch heads home after record-setting mission
Christina Koch, veteran of six spacewalks outside the International Space Station -- including the first all-female excursion -- will join a Russian commander and an Italian flight engineer for a fiery plunge back to Earth early Thursday, setting a new world record for the longest single flight by a female astronaut.
Astronauts finish repairs to space station cosmic ray detector
During a fourth spacewalk Saturday to wrap up repairs of the coolant system in a $2 billion cosmic ray detector, Italian astronaut Luca Parmitano and Drew Morgan discovered a leak in one of eight coolant lines that were spliced into a new pump module during three earlier excursions. But Parmitano was able to tighten a fitting on the line and the astronauts were able to complete the repair work, setting the stage for the instrument to resume science operations.
Spacewalkers complete another round of solar array battery replacements
It took NASA more than 50 years to stage its first all-female spacewalk last October. It took three months before the second on Jan. 15 and just five days more for the third on Monday, a successful six-hour 58-minute excursion to finish installing a set of new solar array batteries aboard the International Space Station.
Koch, Meir continue space station battery replacements on successful spacewalk
Astronauts Christina Koch and Jessica Meir floated back outside the International Space Station Wednesday for history's second all-female spacewalk, installing two powerful new lithium-ion batteries on the far left end of the lab's solar power truss.
Koch marks record stay in space for female astronaut
Astronaut Christina Koch, launched to the International Space Station in March, marks her 289th day in space Saturday, breaking retired astronaut Peggy Whitson's world record for the longest single spaceflight by a female.
NASA, Boeing clear Starliner for Friday launch
Boeing's Starliner capsule, carrying an instrumented astronaut test dummy nicknamed "Rosie," is on track for launch Friday on an unpiloted test flight to the International Space Station, mission managers said Tuesday. The flight is a major milestone in NASA's push to resume launching U.S. crews from American soil.
Astronauts perform third spacewalk to fix cosmic ray detector
After prepping their patient -- a $2 billion cosmic ray detector -- during two earlier spacewalks, two space station astronauts ventured back outside for a third outing Monday to carry out what amounted to transplant surgery, installing replacement coolant pumps in a bid to revive the costly instrument and extend its life.
Spacewalkers continue repair of cosmic ray detector
In a complex bit of orbital surgery, two spacewalking astronauts cut into a $2 billion cosmic ray detector Friday, venting away life-sustaining carbon dioxide refrigerant and then snipping eight coolant lines the size of soda straws to prepare the high-tech "patient" for a coolant pump transplant.
Astronauts complete bonus objectives in first in series of AMS repair spacewalks
Two astronauts ventured outside the International Space Station Friday for the first of four spacewalks to repair a $2 billion cosmic ray detector, breezing through work to prep the device for invasive surgery to splice in new coolant pumps and extend the instrument's life probing the composition of the universe.
