Not Quite As Reliable As You Might Expect

Mark Eby — 12/28/2004 2:44:17 AM (archived)

In-Situ utilization is based on sending the factories before humans and not sending humans until fuel production is complete. Zubrin's plan includes a second factory to produce an entire second batch of fuel while the mission occurs. If not used, it fuels the next return mission. Extreme reliability comes from planning rather than equipment in this scenario. Of course we need to be pretty sure it will work before spending monry on sending it. I sure don't like the idea of going their to stay on the first try as some propose. As a ChemE I think the process is a piece of cake compared to many current industrial processes. Of course it needs to be to be operated totally automatically. It should not however be hard to build or test.

Happy Holidays,
Mark
