===Earth–Moon===
Earth–Moon {{L1|nolink=yes}} allows comparatively easy access to lunar and Earth orbits with minimal change in velocity and this has as an advantage to position a habitable [[space station]] intended to help transport cargo and personnel to the Moon and back. The [[SMART-1]] mission <ref>[http://www.moontoday.net/news/viewsr.html?pid=14345 SMART-1: On Course for Lunar Capture | Moon Today – Your Daily Source of Moon News<!-- Bot generated title -->] {{webarchive|url=https://web.archive.org/web/20051102120549/http://www.moontoday.net/news/viewsr.html?pid=14345 |date=2 November 2005 }}</ref> passed through the L<sub>1</sub> Lagrangian Point on 11 November 2004 and passed into the area dominated by the Moon's [[gravity|gravitational]] influence.

Earth–Moon {{L2|nolink=yes}} has been used for a [[communications satellite]] covering the Moon's far side, for example, [[Queqiao relay satellite|Queqiao]], launched in 2018,<ref name="magpie-earth-moon-l2">{{cite magazine |last=Jones |first=Andrew |title=Chang'e-4 relay satellite enters halo orbit around Earth-Moon L2, microsatellite in lunar orbit |url=https://spacenews.com/change-4-relay-satellite-enters-halo-orbit-around-earth-moon-l2-microsatellite-in-lunar-orbit/ |magazine=SpaceNews |date=14 June 2018}}</ref> and would be "an ideal location" for a [[propellant depot]] as part of the proposed depot-based space transportation architecture.<ref name="aiaa20100902_p4">{{cite web |last1=Zegler |first1=Frank |title=Evolving to a Depot-Based Space Transportation Architecture |url=http://www.ulalaunch.com/uploads/docs/Published_Papers/Exploration/DepotBasedTransportationArchitecture2010.pdf |work=AIAA SPACE 2010 Conference & Exposition |publisher=AIAA |access-date=25 January 2011 |first2=Bernard |last2=Kutter |date=2 September 2010 |page=4 |quote=L<sub>2</sub> is in deep space far away from any planetary surface and hence the thermal, micrometeoroid, and atomic oxygen environments are vastly superior to those in LEO. Thermodynamic stasis and extended hardware life are far easier to obtain without these punishing conditions seen in LEO. L<sub>2</sub> is not just a great gateway—it is a great place to store propellants. ...&nbsp;L<sub>2</sub> 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 suppressing their size and effectively minimizing the near-Earth boiloff penalties. |archive-url=https://web.archive.org/web/20140624125633/http://www.ulalaunch.com/uploads/docs/Published_Papers/Exploration/DepotBasedTransportationArchitecture2010.pdf |archive-date=24 June 2014 |url-status=dead }}</ref>
