LiftPort has a clock counting down to 27 October 2031 on their website. The US-based company believes that, on this date, they will achieve the construction of a space elevator.
The concept was first considered in 1895 when Russian scientist Konstantin Tsiolkovsky proposed using the Eiffel Tower in Paris as the base of a tower that would reach from the ground up to an altitude of 35,790 kilometres above sea level. This is the altitude necessary to achieve geostationary orbit in which a satellite remains fixed over a point on the earth below.
