SpaceX’s rocket just exploded. Here’s why that’s such a big deal.

An unmanned SpaceX Falcon 9 rocket bound for the International Space Station exploded a couple of minutes after liftoff Sunday morning. It was the third cargo mission to the space station to be lost in recent months.

Elon Musk, SpaceX's founder tweeted that "there was an overpressure event in the upper stage liquid oxygen tank." He added: "That's all we can say with confidence right now. Will have more to say following a thorough" analysis.

NASA officials said it was not clear what caused the explosion. During an afternoon press conference William Gerstenmaier, NASA's associate administrator for human exploration and operations, said there was "no negligence here."

The three failures from three different launch providers show "the challenges facing engineering and the challenges facing space flight in general."

The rocket took off from Cape Canaveral, Fla., at 10:21 a.m., and everything seemed fine until 2 minutes at 19 seconds. Then video of the launch showed harrowing, if now familiar, images of a rocket exploding into a plume of smoke. The Falcon 9 was carrying more than 4,000 pounds of food and supplies to the space station, where American Scott Kelly is spending a year. There were no astronauts onboard.


The explosion also lost many student experiments and a water filtration system. Also onboard was a piece of hardware that would be used to help two new crew vehicles dock to the station.

SpaceX, Boeing on Track to Take Astronauts to Space Station by 2017

The agency will use the partnership to end dependency on Russia

SpaceX has completed the first certification milestone in its CCP commitment, and will spend much of 2015 testing abort solutions for its formerly cargo-only Dragon capsule. (Abort procedures are more critical in crewed missions.) A launchpad abort will be tested in the next two months at Cape Canaveral, and an in-flight abort test will follow "later this year," according to SpaceX President and COO Gwynne Shotwell. Uncrewed missions to the ISS with the new capsule will start in 2016, and the company is still working out the makeup of its first test flight crew.

"I DON'T EVER WANT TO HAVE TO WRITE ANOTHER CHECK TO ROSCOSMOS."

The company is also working on outfitting its Dragon capsule with propulsive landing, Shotwell said, which could improve reusability by dispensing with the need to splash down in water. Instead, the capsule would land right at Johnson Space Center, using rockets on the bottom to help control the descent. That's not the only new technology the company is working on. It hopes to outfit its Falcon 9 rockets with wings and retrorockets so they can land on autonomous barges in the ocean.

Boeing has completed the first two certification milestones for its CST-100 spacecraft. NASA has signed off on parts of its commercial crew operation, including designs for the control center, training systems, flight simulators, and software. Boeing has also started building its crew access tower on the Atlas V launchpad, and that construction will continue in between uncrewed Atlas V launches.

The CST-100 will undergo a critical design review in March, and if approved, will let the company launch "full-bore" into manufacturing, according to VP and General Manager of Boeing Space Exploration John Elbon. Boeing's spacecraft can fit up to seven crew members, and is also being designed with reusability in mind. According to Elbon, the plan is for the capsule to be recovered, refurbished, and reused up to 10 times.

When asked how this all fits in with the 2016 budget, Bolden said he's "very optimistic." "Congress has, I think, kind of started to understand the critical importance of commercial crew and cargo. They've seen, as a result of the performance of our providers, that this is not a hoax. It's not a myth. It's not a dream," he said. "It's something that really is happening."
