Zegler, Frank. Evolving to a Depot-Based Space Transportation Architecture(нявызн.)(недаступная спасылка). AIAA SPACE 2010 Conference & Exposition. AIAA (2 верасня 2010). — «L2 is in deep space far away from any planetary surface and hence the thermal, micrometeoroid, and atomic oxygen environments are vastly suberior to those in LEO. Thermodynamic stasis and extended hardware life are far easier to obtain without these punishing conditions seen in LEO. L2 is not just a great gateway- it is a great place to store propellants.... L2 is an ideal location to store propellants and cargos: it is close, high energy, and cold. More importantly, it allows the continuous onward movement of propellants from LEO depots thus subpressing their size and effectively minimizing the near-earth boiloff penalties» Архівавана з першакрыніцы 24 жніўня 2011.
