Live coverage: SpaceX resupply mission arrives at space station

Taking another step toward flying space tourists to the edge of space, Jeff Bezos’s space company Blue Origin again flew its New Shepard suborbital booster Thursday with a package of microgravity research experiments.

A SpaceX Falcon 9 rocket ignited its nine kerosene-fueled Merlin engines on the launch pad at Cape Canaveral on Tuesday evening in a critical milestone before liftoff with a commercial Thai communications satellite later in the week.

The three newest residents of the International Space Station sped into orbit Wednesday aboard a Soyuz launcher after liftoff into an overcast sky over the Baikonur Cosmodrome in Kazakhstan. These photos show the crew putting on their spacesuits and their mid-afternoon launch.
