Boeing said Tuesday it is “making excellent progress” toward launching a second unpiloted test flight of its Starliner crew capsule to the International Space Station by the end of this year or in early January, setting the stage for the first Starliner demonstration mission with astronauts in mid-2021.

The next three-person crew will launch to the International Space Station sometime between July 23 and July 25 after a two-month delay triggered by the failure of an unmanned Progress resupply mission in April, Russian officials said Tuesday.

SpaceX’s Falcon 9 rocket launched from Cape Canaveral on Monday after a 49-minute weather hold to wait for clouds to thin out overhead. The rocket finally lifted off into an overcast sky with a communications satellite built for Turkmenistan.
