SpaceX successfully launches used Dragon spacecraft for first time ever

SpaceX reached another historic milestone Saturday evening by sending a used Dragon spacecraft into orbit.

The launch — which happened at 5:07 pm ET from Kennedy Space Center in Florida — came after a two-day delay. Liftoff was originally scheduled for Thursday evening, but that plan was scrubbed due to a lightning storm.

The pioneering company, headed by Tesla CEO Elon Musk, has proven it can reuse a first-stage rocket booster, which blasts the spacecraft toward orbit. This was the first time it’s reused the craft that actually goes into orbit.

The Dragon spacecraft sits at the very top of SpaceX’s Falcon 9 rocket and is designed to detach from the rocket once in space. It then ferries the cargo to the orbiting space station. The craft that will be used in this mission was previously flown in a September 2014 trip to the space station.

SpaceX has completed 10 resupply missions to the ISS since 2012, and, so far, it’s used a different Dragon each time.

Reusing a spacecraft isn’t new. The NASA space shuttles, for example, made multiple trips to orbit.

But the endeavor is a landmark for the growing commercial space industry. Traditionally, space travel has been the work of governments, because corporations have been averse to the daunting risks and astronomical costs involved in space travel. But over the past decade-plus, SpaceX — and a few other competing private space companies like Blue Origin, United Launch Alliance and Orbital ATK — have upended that notion.

The Dragon will whisk through orbit until it nears the space station on June 4. Then, a giant robotic arm attached to the space station will swing out to capture the Dragon. It can then dock with the station, where crew members on board can harvest its supplies.

On this trip, the Dragon will deliver nearly 6,000 pounds of supplies — everything from food for the crew to fruit flies and rodents that will be used in various experiments.

The space station currently has three astronauts on board: two from the United States, and one from Russia. Two people — cosmonaut Oleg Novitskiy of Russia and French astronaut Thomas Pesquet of the European Space Agency — recently left the station and returned to Earth on Friday. They spent 194 days on board.

The Dragon will stay docked for about a month, and it will be loaded with lab results and garbage before it heads home. The Dragon will then make a splash landing in the ocean, where it can be recovered by SpaceX.

Reusing a spacecraft marks another huge step forward in SpaceX’s efforts to bring down the cost of spaceflight.

In March, SpaceX became the first company to launch, land and then reuse the first stage of an orbital-class rocket. Musk also said the company recovered at least a portion of the rocket’s fairing — a rocket add-on that can house satellites — after that launch.

The first-stage booster is the most expensive piece of the rocket, according to Musk, accounting for up to 60% of the rocket’s $62 million sticker price.

SpaceX does not publicly say how much the Dragon spacecraft is worth. But considering NASA pays SpaceX about $133 million for each mission, and that price would include the cost of the rocket and the Dragon, the spacecraft is likely worth tens of millions of dollars.

It’s not clear how much SpaceX had to spend to refurbish the Dragon. But the company will undoubtedly save a significant chunk of cash by reusing it.

SpaceX’s Hans Koenigsmann said at a press conference Wednesday that the company is looking to make back some of the money it has poured into technology development.

“We’ve invested a significant amount of money that we need to recover,” Koenigsmann said.

The CRS-11 mission Thursday will not use a pre-flown rocket. NASA tends to be extra cautious about taking on added risks, though NASA ISS program manager Kirk Shireman said NASA is “working on” approving flights with used rockets.

The next SpaceX launch with a used rocket will be a June 15 mission for BulgariaSat.
