Why SpaceX is delaying its first human crewed flight

The commercial spaceflight company, SpaceX, plans to send humans into space in 2018, months after the launch was originally scheduled.

The private spaceflight company SpaceX confirmed plans to delay the launch of its crewed spacecraft from 2017 to 2018, just months after a launchpad explosion destroyed an uncrewed craft and its cargo. 

The company, which is known for its unconventional approaches to rocketry and its plans to take humans to Mars, expressed caution at a meeting of the NASA Advisory Council’s human exploration and operations committee in November. This week, NASA announced and SpaceX confirmed their plans to delay both crewed and uncrewed test flights using the Crew Dragon craft.

“We are carefully assessing our designs, systems, and processes taking into account the lessons learned and corrective actions identified,” SpaceX said in a statement. “Our schedule reflects the additional time needed for this assessment and implementation.”

September’s launch pad explosion of a Falcon 9 rocket was a shock for SpaceX. The company has spent the months since the explosion reconsidering their procedures and designs.

A joint investigation conducted by SpaceX, NASA, the US Air Force, and the Federal Aviation Administration attributed the explosion to a problem with SpaceX’s fueling process. Unlike other spaceflight companies, SpaceX uses a cryogenic propellant, a super-chilled mixture of liquid oxygen and kerosene that is intended to provide rockets with more boost than a less dense fuel could.

After the launchpad explosion, The Christian Science Monitor’s Joseph Dussault reported that some experts have expressed concern in the past about SpaceX’s launch timeframe. Dussault writes:

SpaceX has attributed the malfunction to an “anomaly” on the launch pad. Some industry experts, such as former NASA official Scott Pace, expressed concern after the company’s failed launch.

“SpaceX is running a punishing schedule,” Pace, who is now the director of the Space Policy Institute at George Washington University, told The New York Times. “There is probably some human factor involved here. To what extent was human error part of this? And if so, why? Are you running your people too hard? What are your safety requirements?”

But NASA and other experts have stressed that, given the scope of the company’s work, scattered mishaps are normal. Even after Thursday’s explosion, SpaceX’s success rate hovers near the mid-90 percent range.

Although the first crewed flight in a Crew Dragon craft was originally scheduled for late 2017, SpaceX now says that it expects to run an uncrewed test in November 2017. The first crewed launch is now expected to take place in May, 2018.

There are currently two companies working with NASA on its Commercial Crew program, through which commercial spaceflight companies will eventually send astronauts into space.

The other company involved in the program, Boeing, has also delayed its own flights twice, and is now expected to first send humans into space in August, 2018.

Dear Reader,

About a year ago, I happened upon this statement about the Monitor in the Harvard Business Review – under the charming heading of “do things that don’t interest you”:

“Many things that end up” being meaningful, writes social scientist Joseph Grenny, “have come from conference workshops, articles, or online videos that began as a chore and ended with an insight. My work in Kenya, for example, was heavily influenced by a Christian Science Monitor article I had forced myself to read 10 years earlier. Sometimes, we call things ‘boring’ simply because they lie outside the box we are currently in.”

If you were to come up with a punchline to a joke about the Monitor, that would probably be it. We’re seen as being global, fair, insightful, and perhaps a bit too earnest. We’re the bran muffin of journalism.

But you know what? We change lives. And I’m going to argue that we change lives precisely because we force open that too-small box that most human beings think they live in.

The Monitor is a peculiar little publication that’s hard for the world to figure out. We’re run by a church, but we’re not only for church members and we’re not about converting people. We’re known as being fair even as the world becomes as polarized as at any time since the newspaper’s founding in 1908.

We have a mission beyond circulation, we want to bridge divides. We’re about kicking down the door of thought everywhere and saying, “You are bigger and more capable than you realize. And we can prove it.”

If you’re looking for bran muffin journalism, you can subscribe to the Monitor for $15. You’ll get the Monitor Weekly magazine, the Monitor Daily email, and unlimited access to CSMonitor.com.
