Lilemong tsa bo-1990, Setsi sa Wisconsin sa Space Automation & Robotics se ile sa sebelisana 'moho le Quantum Devices Inc. ho nts'etsapele mohloli oa leseli o sebetsang haholoanyane. Ba sebelisitse li-diode tse ntšang leseli (li-LED) tlhahisong ea bona, Astroculture3. Astroculture3 ke kamore ea kholo ea limela, e sebelisang mabone a LED, ao NASA e a sebelisitseng ka katleho mesebetsing e 'maloa ea Space Shuttle.
Kapele, NASA e ile ea sibolla lits'ebetso tse ka bang teng tsa leseli la LED eseng feela bakeng sa bophelo bo botle ba limela, empa le bakeng sa bo-rasaense ka bobona. Ho phela maemong a tlase a khoheli, lisele tsa batho ha li tsosolose kapele, 'me bo-rasaense ba na le tahlehelo ea masapo le mesifa. Kahoo NASA e ile ea retelehela ho phekolo ea photobiomodulation (PBMT). Kalafo ea photobiomodulation e hlalosoa e le mofuta oa phekolo ea leseli o sebelisang mehloli ea leseli e seng ea ionizing, ho kenyeletsoa le lasers, diode tse ntšang leseli, le/kapa leseli la broadband, ho spectrum ea electromagnetic e bonahalang (400 - 700 nm) le haufi le infrared (700 - 1100 nm). Ke ts'ebetso e seng ea mocheso e kenyeletsang li-chromophores tsa tlhaho tse hlahisang liketsahalo tsa photophysical (ke hore, linear le nonlinear) le photochemical maemong a fapaneng a baeloji.
