Separation! Crew Dragon, SpaceX Demo-2 Crew Arrive in Orbit

SpaceX’s Crew Dragon spacecraft separates from the second stage of the Falcon 9 rocket, carrying NASA astronauts Robert Behnken and Douglas Hurley to the International Space Station on the agency’s SpaceX Demo-2 mission.

Twelve minutes into the flight of the SpaceX Crew Dragon carrying NASA astronauts Robert Behnken and Douglas Hurley, the spacecraft separated from the Falcon 9 rocket’s second stage, signaling the end of the climb to space. NASA’s SpaceX Demo-2 mission, a final end-to-end flight test of the company’s crew transportation system, is underway with the return of human spaceflight capability to U.S. soil.

The Crew Dragon, Behnken and Hurley are embarking on a 19-hour pursuit of the International Space Station.

“Thanks for flying on Falcon 9 today – we hope you enjoy the mission,” said SpaceX Chief Engineer Bala Ramamurthy.

“It was incredible. Appreciate all the hard work. Thanks for the great ride to space,” the crew responded.

The Crew Dragon’s nosecone is opening. This rounded cover at the top of the spacecraft protects the docking system and the guidance, navigation and control system. The spacecraft’s environmental control and life support system is running as well.

Second-Stage Engine Cutoff, First Stage Begins Descent Toward Drone Ship

SECO! The SpaceX Falcon 9 rocket’s second-stage Merlin engine shut down as planned. Separation of the Crew Dragon spacecraft from the second stage is coming up just over three minutes from now.

The Falcon 9 rocket’s first stage is descending toward SpaceX’s drone ship, “Of Course I Still Love You,” waiting in the Atlantic Ocean.

Main Engine Cutoff; Second Stage Continues the Flight

MECO! Main engine cutoff. The nine Merlin engines powering the Falcon 9 rocket’s first stage shut down as expected, followed by separation of the first stage from the second stage. The second stage’s single Merlin engine has taken over the task of delivering the Crew Dragon spacecraft, carrying NASA astronauts Robert Behnken and Douglas Hurley, safely to orbit. This second-stage burn will last approximately six minutes.

LIFTOFF! NASA’s SpaceX Demo-2 Launches the Commercial Crew Era

Liftoff! The SpaceX Falcon 9 rocket carrying NASA astronauts Robert Behnken and Douglas Hurley aboard the company’s Crew Dragon spacecraft launched from Kennedy Space Center’s historic Launch Pad 39A at 3:22 p.m. EDT, kicking off a critical final flight test of the SpaceX crew transportation system. The commercial crew era has officially begun with this launch of American astronauts on an American spacecraft from American soil.

Control of the flight has been transferred from the SpaceX launch control team at Kennedy to the mission control team at the company’s headquarters in Hawthorne, California.

The nine Merlin engines on the Falcon rocket’s first stage are generating more than 1.7 million pounds of thrust as the vehicle climbs away from Florida’s Space Coast. At about one minute into the flight, the rocket will pass through Max Q, the point of peak mechanical stress on the rocket.

NASA’s SpaceX Demo-2: Launch Minutes Away

NASA’s SpaceX Demo-2 mission is minutes away from liftoff at 3:22 p.m. EDT from the agency’s Kennedy Space Center in Florida.

The crew’s displays inside the Crew Dragon spacecraft are configured for flight.

“Have an amazing flight and enjoy those views of our beautiful planet,” the SpaceX CORE said to astronauts Robert Behnken and Douglas Hurley.

The crew answered, “It is absolutely our honor to be part of this huge effort to get the United States back” in the business of human spaceflight.

Here’s a look at the major milestones to come during the climb to space. (Times are shown in “L+time” – minutes and seconds after launch.)

Less than 20 Minutes Until Launch

Liftoff of the SpaceX Falcon 9 rocket and Crew Dragon spacecraft on NASA’s SpaceX Demo-2 mission to the International Space Station remains on schedule for 3:22 p.m. EDT from Kennedy Space Center’s Launch Complex 39A. Propellant loading operations continue as expected. Crew members Douglas Hurley and Robert Behnken are strapped in and have closed their visors.
