Giant rocket explosion also took out asteroid mining spacecraft

Aboard the Antares rocket that exploded spectacularly moments after liftoff was a tiny demonstration spacecraft built by Planetary Resources, an asteroid mining firm.

The rocket explosion that destroyed a cargo vessel bound for the International Space Station Tuesday (Oct. 28) also took out an asteroid-mining company's first spacecraft.

Orbital Sciences Corp.'s Antares rocket exploded in a huge fireball just seconds after launching from NASA's Wallops Flight Facility in Virginia Tuesday evening. The crash caused no injuries but destroyed Orbital's unmanned Cygnus capsule, which was toting 5,000 lbs. (2,268 kilograms) of food, supplies and other gear to the International Space Station for NASA.

The plan was to deploy Arkyd 3 (also known as A3), which measured just 12 by 4 by 4 inches (30 by 10 by 10 centimeters), from the space station into free-flying low-Earth orbit, where it would test out avionics, control and other systems for future asteroid-prospecting spacecraft.

Planetary Resources is taking the loss of A3 in stride.

"While we are saddened about the unfortunate consequences of this launch failure, our own development schedule, budget and plan are practically unaffected," Planetary Resources President Chris Lewicki wrote in a blog post today (Oct. 29).

"In fact, we are already hard at work developing our next test vehicle, the Arkyd 6, which is planned for launch in Q3 2015," he added. "It will build on the learnings from our development of the A3 and iterate to our next level of design. Multiple spacecraft and safety in numbers is part of our strategy, and we will continue with it for just these occasions."

Representatives of the Washington state-based firm, which counts Google execs Larry Page and Eric Schmidt among its investors, have said they hope to launch asteroid-hunting "Arkyd 100" scouts to low-Earth orbit in the next few years. Further down the road, Planetary Resources plans to launch other robotic probes to investigate potential mining targets up close, in deep space.

Eventually, the company aims to extract and sell asteroid resources, starting with water. Asteroid water can be split into oxygen and hydrogen — chief components of rocket fuel — allowing voyaging spaceships to top up their tanks without returning to Earth, mining advocates say.

Editor's Note: NASA officials are urging residents of the area around Wallops Flight Facility to stay away from any pieces of rocket debris that might wash up on shore or be found on land. If you think you may have found pieces of the rocket, please call the incident response team at (757) 824-1295.

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.
