As NASA shifts focus to Mars, will private companies look to the moon?

Speaking at the SpaceCom Expo in Houston, NASA Administrator Charles Bolden predicted that private businesses will 'assume a lead role' in returning humans to the moon.

Charles Bolden, NASA's administrator, addresses a crowd at the first annual SpaceCom expo. Bolden spoke about the important role that private and commercial space companies will play in helping NASA send humans to distant space locations.

Work needs to be done by commercial companies to take up the responsibility of supporting science and human astronauts in low-Earth orbit and beyond, according to NASA Administrator Charles Bolden.

Speaking yesterday (Nov. 17) at the first annual SpaceCom Expo here, Bolden talked about the need for a marketplace in low-Earth orbit where "NASA is not the only customer." This could potentially include maintaining the American side of the International Space Station, which serves as a one of a kind microgravity laboratory and testing ground for human trips into deep space. And Bolden doesn't imagine the work of private companies will stop there. 

In reference to the commercial space market that has already begun to blossom, Bolden said, "Now that the doors have been kicked open, I'm looking forward to new ideas about what we do next and how we keep that market humming. Who has a plan for non-NASA astronauts to conduct low-Earth orbit ops? That's my question." [Building the International Space Station (Photos)]

Looking even further into the future, Bolden added, "As we focus on sending humans to Mars, it will likely be commercial companies and international partners who assume a lead role in taking humans back to the surface of the moon. And I'm all for that."

Bolden was not the only speaker at SpaceCom discussing the need for commercial companies to take over more responsibilities on the station, or to create new orbiting laboratories to replace it. NASA is committed to maintaining its portion of the station through 2024, but as Bolden said, the agency would like to dedicate its resources to more ambitious goals, like sending humans to Mars. But, as was noted by commercial spaceflight leaders at another recent conference, a human presence in low-Earth orbit provides information and training for human journeys to more distant space locations, and many leaders advocate for maintaining a human presence in low-Earth orbit while pursuing human trips to the moon or Mars.

The space station is also an invaluable scientific resource. The weightless environment provides a unique variable for testing all kinds of physical, chemical and biological processes. Currently, scientists must apply to NASA to have their experiments taken to the orbiting laboratory, but some commercial companies are beginning to change that. NanoRacks allows customers to send small experiments to the station, and Made In Space, the company that sent the first 3D printer into microgravity, can use its machine for commercial purposes. Companies with more capital can also pay to have scientific payloads launched on top of commercial rockets, but there is currently no option to put an experiment in space for a long duration.

Bolden noted that commercial spaceflight companies will be filling a larger role in NASA's human spaceflight program than ever before, when private companies begin delivering NASA astronauts to the International Space Station as part of the Commercial Crew Program. NASA has now officially ordered a CST-100 space taxi from Boeing. SpaceX was also awarded a contract to support the construction of its Dragon crew capsule, although NASA has not yet ordered one of the vehicles. Currently, NASA astronauts are launched to the space station aboard the Russian Soyuz capsule.

"If all goes well and we get full support from Congress, my hope is we will fly the first commercial crew capsules in late 2017, early 2018," Bolden said. "For the first time in quite some time we will no longer be dependent on any other nation to get our crews into space, and for us in this day and age that is critically important."

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.
