Live coverage: Soyuz MS-14 docks at space station

Check out a pictorial retrospective on Friday’s launch of three new space station crew members from Kazakhstan, riding an iconic Soyuz booster to orbit and arriving at the 250-mile-high research complex less than six hours later.

Loaded with investigations into chemotherapy drugs with reduced side effects and radiation detectors for homeland security, a plant-growing chamber to promote future food harvesting in space and a technology demonstration for sample-return capsules, a commercial Cygnus cargo vessel will be sent to the International Space Station next week.

With one last task to carry out, a space station Cygnus cargo ship loaded with trash and no-longer-needed equipment fell back to Earth Wednesday, hitting the discernible atmosphere 60 miles or so above the Pacific Ocean at nearly 5 miles per second.
