SpaceX to Launch 1st Reused Dragon Spacecraft Today: Watch It Live

SpaceX is right on track to launch a reused Dragon spacecraft for the first time today (June 1), and you can watch the momentous mission live.


Seated atop a SpaceX Falcon 9 rocket, the Dragon will lift off from the historic Pad 39-A at NASA’s Kennedy Space Center in Florida at 5:55 p.m. EDT (2155 GMT), beginning its three-day journey to deliver cargo to the International Space Station.

The last time this particular vessel flew to space was with the CRS-4 cargo mission in 2014. That mission was one of the 12 that SpaceX has agreed to fly for NASA, to deliver supplies and science experiments to the International Space Station. Thursday’s flight, titled CRS-11, will be the 11th, carrying about 6,000 lbs. (2,700 kilograms) of cargo. [6 Fun Facts About SpaceX]

SpaceX’s robotic Dragon capsule is seen docked to the International Space Station shortly after arriving on Sept. 23, 2014. This same Dragon is poised to launch to the orbiting lab again on June 1, 2017.

After they undock from the space station, Dragon spacecraft have always returned to Earth by splashing down in the ocean. But never before has one of these capsules been retrieved, refurbished and reflown.

In another historic first, SpaceX launched and landed a used Falcon 9 rocket in March. With Thursday’s flight, the private spaceflight company aims to move one giant leap closer to full reusability of its launch vehicles — a lofty goal, but one that would help the spaceflight industry to spare the cost of continuing to build non-reusable rockets in the future.


Once SpaceX has demonstrated the reusability of both its first-stage rocket booster and the Dragon capsule, the next big step is to make the second-stage rocket booster and payload fairing reusable as well, Hans Koenigsmann, vice president of flight reliability at SpaceX, said during a news conference on Wednesday (May 31).

“I’m not sure how long it will take until we refly [payload] fairings, but I would expect us to take some time, similar to the first stage,” Koenigsmann added.


After the CRS-11 first stage separates, it will return to Cape Canaveral Air Force Station in Florida for what will be SpaceX’s fifth rocket landing on land. SpaceX has also landed six Falcon 9 rocket boosters on drone ships, having recovered a total of 10 boosters so far.
