'''SPADEX''' or Space Docking Experiment is a twin spacecraft mission being developed by [[Indian Space Research Organisation]] to mature technologies related to orbital [[Space rendezvous|rendezvous]], [[Spacecraft Docking and Berthing Mechanisms|docking]], [[formation flying]] and remote [[robotic arm]] operations, with scope of applications in human spaceflight, in-space satellite servicing and other proximity operations.<ref name=":0">{{Cite web|url=https://www.isro.gov.in/sites/default/files/annualreport2018-19.pdf|title=Department of Space Annual Report 2018-19|last=|first=|date=27 May 2019|website=|url-status=live|archive-url=https://web.archive.org/web/20190527183016/https://www.isro.gov.in/sites/default/files/annualreport2018-19.pdf|archive-date=27 May 2019|access-date=2 October 2019}}</ref>
