Video: SpaceX launches first mission of 2020 (members only)

A refurbished SpaceX Crew Dragon spaceship linked up with the International Space Station early Saturday more than 260 miles above Earth, delivering four veteran astronauts to the orbiting research complex and temporarily raising the lab’s crew complement to 11.

The launch of a NASA satellite to study the behavior of plasma in Earth’s ionosphere has been delayed to early next year, giving engineers time to resolve concerns with the separation system on its air-launched Pegasus XL booster.

Vice President Mike Pence plans to travel to the Kennedy Space Center on May 27 for the first launch of astronauts from a U.S. spaceport since 2011.
