> However, even a catastrophic Kessler scenario at LEO would pose minimal risk for launches continuing past LEO, or satellites travelling at medium Earth orbit (MEO) or geosynchronous orbit (GEO). The catastrophic scenarios predict an increase in the number of collisions per year, as opposed to a physically impassable barrier to space exploration that occurs in higher orbits.

Kessler Syndrome has always struck me as a problem that, should it become an actual issue, we should be able to solve. There is even mention of a couple potential solutions on the Wikipedia page.
