While descending from orbit can the air be thin enough for a glider type blimp to slowly shed speed?
Could a blimp skim the atmosphere around a planet, slowly decreasing air speed, without the need of a traditional heat shield?
Like a hydroplaning ship on water, the glider-like blimp would be using the air under it to skip most upper atmosphere during orbital entry. I don't think this has been attempted yet, or does this have a name other than 'skip reentry'?
It would look like the picture below, but with more skips at smaller angles of attack, and more orbits.
