We have a plan…or do we?

On Thursday NASA released a plan for getting humans to Mars, the 36 page Journey to Mars: Pioneering Next Steps in Space Exploration.

journeytomars-coverThe document is definitely much more of a PR brochure than an actual mission plan, but of course this is for public consumption.

It includes three phases:  “Earth Reliant” (ISS-based), “Proving Ground” (cis-Lunar) and “Earth Independent” (Mars and vicinity), “each with increasing challenges as humans move farther from Earth.”

It is positive to hear NASA publicly proclaim, “Like the Apollo Program, we embark on this journey for all humanity. Unlike Apollo, we will be going to stay.”  It’s quite a reversal from a few years ago where even mentioning Mars seemed to be a taboo.

Unfortunately, this “plan” does differ from Apollo in other key areas: it lacks the political mandate, budget and timeframe to provide a reasonable chance at success, at least in our lifetime.  This isn’t NASA’s fault, of course; it’s a political reality that must be overcome.

Other problems include the plan’s attempt to justify past expenditures and accommodate other, irrelevant initiatives.  The role of ISS is certainly larger than it needs to be, asteroid capture is unnecessarily included, and apparently Solar Electric Propulsion will be playing a role.  Too many things that don’t have a lot to do with getting to Mars.

There’s also no mention of a Mars fly-by mission.  Such a mission would be achievable within NASA’s current budget and more importantly within two presidential terms.  It would also significantly advance and provide a real “proving ground” for many of the critical technologies mentioned in this document.  Maybe more important, it would likely boost the political and public support for a full blown Mars landing and settlement program in our lifetimes.  Hopefully a future version of this plan will move in that direction.
