Cue the ultimate low orbit satellite > It is undesirable to have a definition that will change with improving technology, so one might argue
that the correct way to define space is to pick the lowest altitude at which any satellite can remain in orbit,
and thus the lowest ballistic coefficent possible should be adopted - a ten-meter-diameter solid sphere of
pure osmium, perhaps, which would have B of 8×10^−6 m^2/kg and an effective Karman line of z(-4) at the
tropopause from https://arxiv.org/abs/1807.07894 |
