How to watch the historic SpaceX/NASA launch today!

Today, a SpaceX Falcon 9 rocket and Crew Dragon capsule is scheduled to shuttle two NASA astronauts to the International Space Station. This will be the first time humans will launch to space from the United States since 2011 and the first time a private company will take humans offworld. Intrepid science journalist Nadia Drake is at the launchpad reporting on the mission for National Geographic and ABC News. Tune in above for Nadia's live reporting. Liftoff is set for 4:33pm ET, weather and technology permitting. From Nadia's coverage at National Geographic:

The Demo-2 mission is slated to lift off from Kennedy Space Centers Launch Complex 39Athe same pad in Florida that hosted Apollo 11 and STS-135, the last flight of a space shuttle. However, next week's mission represents a new way of getting humans to orbit, in which agencies including NASA purchase rides to space from private companies.For astronauts [Doug] Hurley, 53, and [Bob] Behnken, 49, the Demo-2 flight also presents a rare opportunity: to be the first people to fly in a new type of spacecraft. Behnken and Hurley were specially selected for NASAs commercial crew program back in 2015. Both men are former military test pilotsHurley in the Marines and Behnken in the Air Force. Both are married to fellow astronauts, and the two have been colleagues since joining NASA in 2000 as part of Astronaut Group 18.

Its probably a dream of every test pilot school student to have the opportunity to fly on a brand-new spaceship, and Im lucky enough to get that opportunity with my good friend here, Behnken said recently at a press conference with Hurley.
