Q&A with John Elbon, VP and general manager of Boeing’s space exploration division

The 200th Atlas-Centaur rocket, history some 52 years in the making, will blast off Tuesday from Cape Canaveral to deliver a U.S. Navy mobile communications satellite into orbit.

In the home stretch of nearly a half-year on the International Space Station, four astronauts suited up and rode their SpaceX-owned Crew Dragon “Resilience” spaceship to a new docking port outside the orbiting research lab Monday, a first-of-its kind maneuver for the new generation of commercial crew spaceships.

NASA and SpaceX have delayed the launch of the Crew Dragon “Resilience” spacecraft from the Kennedy Space Center until 7:27 p.m. EST Sunday (0027 GMT Monday) to wait for improved downrange weather and sea conditions, and better onshore winds at the launch site.
