Engineering Planetary Protection into a Spacecraft
on: October 27, 2013, 06:19

I was an intern in the Planetary Protection (PP) Division at the Jet Propulsion Laboratory in Pasadena, CA. I'd like to do research on this topic. Specifically with this thread, I would like to address ways in which engineering controls could be used to keep the spacecraft sterilized as much as possible.

For example, my advisor found that hydrazine, a common spacecraft fuel, is free of bacterial spores (paper attached). Using materials and chemicals/fuels that are free of microbial spores or whose processes can be modified to minimize bacterial contamination will help meet our planetary protection requirements which will be more stringent than anything NASA, the ESA, or Roscosmos had to deal up to this point just because we're dealing with an ocean and possible extant organisms.

At JPL, the division was more closely associated with the engineering divisions instead of the life sciences sections. Indeed, we'll have to closely watch what is being posted in the design and engineering threads on this forum to make sure we remain relevant and consistent.

I'll start posting more about PP and some possible engineering controls we could use once I go through the engineering sections. Please feel free to add your own input right now if you have any.

Is hydrazine toxic to the interiors of the spacecraft like they showed in the film?
