SpaceX abort test serves as practice run for astronauts, rescue teams
A SpaceX Falcon 9 rocket and Crew Dragon capsule were raised vertical at launch pad 39A in Florida late Thursday, setting the stage for a launch day dress rehearsal Friday with NASA astronauts Doug Hurley and Bob Behnken -- the veteran space fliers assigned to the Crew Dragon's first piloted mission later this year -- before a critical in-flight test of the ship's emergency escape system Saturday.
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.
VideoLive coverage: Starliner lands in New Mexico
Boeing's Starliner crew capsule accomplished an early at White Sands Space Harbor in New Mexico at 7:58 a.m. EST (5:58 a.m. MST; 1258 GMT) Sunday to conclude an abbreviated two-day unpiloted test flight after a timing error on the spacecraft shortly after launch prevented it from linking up with the International Space Station as planned.
After redesigns, the finish line is in sight for SpaceX’s Crew Dragon spaceship
Five-and-a-half years ago, SpaceX founder Elon Musk revealed SpaceX's Crew Dragon spacecraft, a sleek-looking human-rated spaceship with 3D-printed engines, a roomy stylized interior and touchscreen controls. Now SpaceX's first ship to ferry astronauts -- with numerous design changes introduced since 2014 -- is about to leave the company's factory for final testing before launching early next year.
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.
After quiet autumn, SpaceX preps for busy December launch schedule
After a lull in launch activity this fall, SpaceX teams at Cape Canaveral are preparing for up to four Falcon 9 missions in December to close out 2019 with a surge of launches.
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.
Complex spacewalk repair work begins Friday
After four years of brainstorming, custom tool development and training, two astronauts plan to venture outside the International Space Station Friday for the first of four spacewalks to repair a $2 billion cosmic ray detector. The excursions are considered the most challenging since work to service the Hubble Space Telescope.
