Despite blowing up an experimental upgrade to its go-to rocket engines, SpaceX says it can continue its record-setting year.
The aerospace company, founded by llionaire tech mogul Elon Musk, has pulled off 16 rocket launches in 2017. That’s double SpaceX’s launch count from last year and a frequency rivaling that of its ggest competitors.
What’s more, SpaceX hopes to lift off three more of its Falcon 9 rockets — a reusable launch vehicle that’s poised to significantly lower the cost of access to space (and maybe save humankind) — before the year’s end.
But as Christian Davenport reported for the Washington Post on Wednesday, an explosion rocked SpaceX’s development facility in McGregor, Texas, over the weekend.
The blast occurred in one of two bays the company uses to test Merlin rocket engines — nine of which line the bottom of every reusable Falcon 9 booster.
“No one was injured and all safety protocols were followed during the time of this incident,” a SpaceX spokesper t Business Insider in a statement. “We are now conducting a tho and fully transparent investigation of the root cause. SpaceX is committed to our current manifest and we do not expect this to have any impact on our launch cadence.”
That doesn’t mean the company doesn’t have a problem or delays to deal with, though.

SpaceX was testing an experimental version of its Merlin rocket engine at the time of the blast, a company source who is familiar with the matter t Business Insider.
All Falcon 9 rockets launched today use a gn called block-four — a kind of ” year” for the rocket system. Saturday’s test was to qualify a more powerful block-five system, which SpaceX has not yet said when it is releasing. (Block-five will help the company launch heavier payloads into higher orts around Eh while being able to land and reuse its boosters, which are the most expensive p of a rocket.)
Surprisingly, the engine was not being purposefully ignited when it exploded: According to the company source, the blast occurred during a “lox drop,” in which liquid oxygen is pumped into a rocket engine to see if it leaks.
“The computers were showing data we didn’t like during that test,” the source said — and shortly after this the explosion happened. “We’re going to investigate what led to that ignition. What does the video show? What do the pos show? What do the computers show?”
Whatever the cause, the testing bay in which the Merlin engine was attached to did not fare well. “It’s a two- to four-week repair ,” the source said.
A nearby testing bay, which is also used to qualify Merlin engines before flight, was also damaged from the explosion — perhaps by flying metal, concrete, or liquid-oxygen-fueled flames.

Yet that repair will take only “two or three days,” according to the source, and block-four testing will soon resume.
“This isn’t going to have any impact on our launches this year or next year. We can make all the block-fours we want,” the source said.
However, SpaceX is pausing development of its block-five Merlin engines not only to investigate the blast, but also make room to keep block-four Merlin engines qualified for flight. This will delay the roll-out of that program until both the investigation closes and the badly damaged bay is repaired.
The company source compared this problem to Toyota delaying the year of its Camry with a “a gger backseat and engine”: Most customers won’t mind, the source said, since last year’s s fine — and the version doesn’t even have a release date.
“But the Toyota Camry fans who trick out their s? They are going to be super-ed about the delay,” the source said.
The last major explosion SpaceX suffered was in September 2016, when a pressure vessel failed and caused a Falcon 9 rocket to blow up during a launch-pad test, destroying a satellite payload on top. The company also lost a payload in 2015, and failed to ferry a “Star Trek” actor’s ashes to space in 2008.
Musk has said he eventually hopes to phase out all of his company’s rocket systems, including the upcoming Falcon Heavy rocket, by building a totally reusable “Big F—ing Rocket” system gned to coze Mars.
