Checking arXiv.org, I notice that SeeSat participant Jonathan McDowell has produced a paper reexamining the "edge of space" question: https://arxiv.org/pdf/1807.07894.pdf The Edge of Space: Revisiting the Karman Line Jonathan C. McDowell Harvard-Smithsonian Center for Astrophysics, 60 Garden St, Cambridge, MA 02138, USA Abstract In this paper I revisit proposed definitions of the boundary between the Earth’s atmosphere and outer space, considering orbital and suborbital trajectories used by space vehicles. In particular, I investigate the inner edge of outer space from historical, physical and technological viewpoints and propose 80 kilometers as a more appropriate boundary than the currently popular 100 km Von Karman line. _______________________________________________ Seesat-l mailing list http://mailman.satobs.org/mailman/listinfo/seesat-lReceived on Tue Jul 24 2018 - 11:43:45 UTC
