Live coverage: Launch readiness review gives approval for final Atlas 5 flight preps
United Launch Alliance and Boeing teams worked through the weekend on closeouts of the Starliner crew capsule, inspections and final outfitting of the Atlas 5 rocket. A launch readiness review Tuesday approved the continuation of final preparations for liftoff from Cape Canaveral Friday of the first Starliner spacecraft on an unpiloted test flight to the International Space Station.
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.
SpaceX fires up Crew Dragon thrusters in key test after April explosion
SpaceX test-fired the Crew Dragon spacecraft's eight SuperDraco abort engines Wednesday at Cape Canaveral, paving the way for a high-altitude rocket escape test and demonstrating engineers have apparently fixed the problem that triggered an explosion during a similar ground firing in April.
Video: Crew Dragon tests abort thrusters at Cape Canaveral
SpaceX conducted a static fire test of the SuperDraco abort thrusters on the company's Crew Dragon spacecraft Wednesday afternoon at Cape Canaveral Air Force Station.
Next three-man Soyuz crew training to have space station to themselves
The next three-man crew to launch on a Soyuz rocket -- comprising two Russian cosmonauts and a veteran NASA astronaut -- is training to have the International Space Station to themselves after their arrival at the orbiting research outpost in April, at least until new U.S. commercial crew ships enter service.
VideoBoeing identifies cause of chute malfunction, preps for Starliner launch
Boeing specialists working inside a former space shuttle hangar in Florida started fueling the company's first spaceflight-ready Starliner capsule this week ahead of the ship's rollout to its launch pad later this month. The fueling milestone is a major step in the Starliner launch campaign, and comes after engineers concluded that human error led to a parachute deployment malfunction during a crew capsule abort test Monday.
