Space X to resupply the International Space Station

This past week the world enjoyed images of the retired space shuttle Enterprise headed for New York city.  It was a nice finish to that long program, but also a reminder of coming changes in how Earth conducts space missions.

Space Exploration Technologies, better known as SpaceX, will test fire its Falcon 9 rocket's engines on 30 April.  Then on 7 May it will attempt to launch into space, and then possibly dock with the International Space Station (ISS).  The Dragon vehicle on top of the Falcon rocket will carry a load of supplies for the ISS, in case the docking maneuver is successful.  If it all works, the Earth will enter a new era in space where private companies may replace government programs.

Right now, the ISS relies on Russian, European and Japanese vehicles for resupply.  Having three options is a good thing, but the costs per mission are high, and none of the three vehicles are re-useable.  The advantage of SpaceX's Dragon vehicle is that it is re-useable, and less expensive.  For instance, the European ATV cargo ship costs 300 million USD to build, while SpaceX will charge NASA only 133 million per resupply run.  If the Falcon can dock with the ISS, SpaceX is slated to carry out 12 of these missions, designated Commercial Resupply Services (CRS).

What's particularly remarkable is that SpaceX only formed their company ten years ago, back in March 2002.  In 2010, they became the first private company to launch a vehicle into orbit and then return it safely to Earth.  This fast-paced development makes one wonder what they can do in the next decade, and if private companies can work in space more efficiently than government programs.   

There are a lot of 'ifs' here.  If the Falcon can dock with the ISS and unload its supplies, it will mean the ISS won't have to rely on the Russian, European and Japanese vehicles.  The bigger picture is that space exploration may transition from a government-only arena to a partnership between private companies and governments.  Will this lead to private corporations dominating space? Or will governments always think that national security interests force them to remain involved? A lot of interesting questions will be answered.

[On 30 April, will feature a webcast of the engine tests on the Falcon 9 rocket at 2:30pm ET.]

  1. National security vs. will be interesting to see this unfold. The scary thing is that if private companies start dominating space, it's highly likely they will not be American companies. Is the 1st Intergalagtic Free Trade Agreement in our near future? ;)

  2. Akopp, I wonder about trade in space, too. I think when someone first mines an asteroid or reaches a moon with precious metals, we'll have to start making agreements. Probably the first part they should do is make it like the oceans here, where if another ship is in danger, you have to help them if possible.

    Thanks for commenting!

  3. Success! The capture was successful an hour ago.

    Responding to the comments; private companies already have a huge presence in space. Satellites are launched several times a month and more than half of them are from private companies. Certainly no private company has intentionally launched anything out of our earth's gravitational orbit. That realm still lies with NASA and its counterparts. I'm guessing the military is out there as well.
    I can see how non government sponsored activities are a bit disconcerting. What is to prevent Space Taliban from hijacking the ISS? (Pretend they have the resources, the technology, and our government ignores them while they make preparations over a period of several years.)

    Certainly if SpaceX was not welcome at the ISS our government would have shut them down a long time ago. Rogue launches by private organizations are likely several decades away but we've already seen government sponsored rogue activities targeting space activities by both China and North Korea. Akopp is right to bring up the point that we should be thinking of this stuff now.

  4. Torger, thanks for following up on this story. I've been waiting to see if the launch and docking were successful. I believe the Dragon vehicle is carrying 1,000 lbs of supplies to unload. Then it'll have to survive re-entry and landing. Very cool.

    The ISS's robot arm will capture the robot Dragon vehicle, which makes me think that robots are the future of space travel and space work. Until we can better withstand the conditions and distances involved, I don't know how big a role humans will have in space.
