Photos: EchoStar 19 launch as seen from press site

Launch of a SpaceX Crew Dragon capsule carrying four astronauts to the International Space Station has been delayed 24 hours to Friday because of bad weather in the Atlantic Ocean where the crew could be forced to ditch in an emergency, NASA announced Wednesday.

With the SpaceX scrub earlier this week and the time needed to convert the Eastern Range over to the Delta 4, liftoff of that rocket carrying an internationally-purchased military communications satellite for the Air Force has been bumped to Saturday evening.

When the first Delta 2 rocket took off on Valentine’s Day 1989, ideas like navigating by smartphone and driving robots on Mars were science fiction. More than 150 launches over the last 30 years helped change all that.
