Oh, Paul, please:

With launch costs of thousands of dollars per pound (and unlikely to come down significantly for the foreseeable future)

They are likely to come down to hundreds, or tens of dollars per pound within a decade, now that we have some actual competition and innovation happening in the industry.

Hazardous Asteroids

may be more common than we thought:

The scientific orthodoxy said that a Chelyabinsk-size event ought to happen every 140 years or so, but Brown saw several such events in the historical record.

Famously, a large object exploded over the Tunguska region of Siberia in 1908. But there have been less-heralded impacts, including one on Aug. 3, 1963, when an asteroid created a powerful airburst off the coast of South Africa.

“Any one of these taken separately I think you can dismiss as a one-off. But now when we look at it as a whole, over a hundred years, we see these large impactors more frequently than we would expect,” said Brown, whose paper appeared in Nature.

But our response, and actions to become a space-faring civilization, remains pathetic.
