| космическая башня (A space tower is a tower that would reach outer space. To avoid an immediate need for a vehicle launched at orbital velocity to raise its perigee, a tower would have to extend above the edge of space (above the 100 km Kármán line),[22] but a far lower tower height could reduce atmospheric drag losses during ascent.
