In an open letter, Apollo 9 astronaut Russell Schweickart questions whether a non-nuclear option for asteroid deflection isn't the more prudent path.

Makes sense, given that a lot of worries are now to do with smaller NEOs - maybe 100m and down - for which it should be easier to develop such technologies - rather than objects like Toutatis. At those sizes, maybe we could even put them somewhere that might be useful later, like L1 or L2.

Of course, there is the old 'you can solve any problem with a Honking Great Nuke' mindset to contend with...

NEO Tugboats may be a good option if you have decades to move it out of the way. But what if the warning time is short. Do you really want to limit your options?

We have no options if the timeframe is short.

Think out of the box. The other side of the equation is evacuation or sheltering. An expediant shelter could be constructed in approximately 24 hours that if constructed properly could protect individuals to approximately the 50 psi overpressure level. That is almost at the jagged edge of infinity.

Think out of the box [...]

Think ecosystem.
