The requirements that an anchored lunar satellite must satisfy are examined, with emphasis on two questions: (1) whether a taut tether which connects the lunar surface with a satellite at the L2 (or L1) equilibrium point can have a stable equilibrium position; and (2) whether a tether of such length (65,000 km) can withstand the stresses that are entailed and meet the necessary technical requirements. Tethers made of different materials (glass, boron, quartz, and Kevlar) are examined, and it is concluded that the above-mentioned requirements are not impossible to satisfy. In particular, it is found that a station with a mass of 2.5 thousand tons can be held by a tether 100-thousand kilometers long with a mass of 100 tons and a cross section of 0.3 mm.
