Video: 4K video replay of SpaceX’s CRS-21 launch (members only)

A Soyuz rocket carrying a Russian commander, a NASA co-pilot and a United Arab Emirates guest cosmonaut blasted off from Kazakhstan Wednesday, chased down the International Space Station and glided in for a picture-perfect docking, kicking off an unprecedented end-of-year schedule that includes up to a dozen spacewalks.

Days after SpaceX opened preorders for Starlink internet service, two more Falcon 9 rockets are set to launch from Florida’s Space Coast as soon as Sunday night and Wednesday morning — weather permitting — to help push the network closer to commercial operations.

Ending months of speculation, Blue Origin, a company owned by Amazon-founder Jeff Bezos, has won a milestone contract to provide first-stage rocket engines for a powerful new booster being designed by United Launch Alliance to replace its current fleet of Atlas and Delta launchers, the companies announced Thursday.
