National Aeronautics and Space Administration zipụrụ ozi ahụ na Altimeter Laser Ọnwa site na nkwukọrịta laser. Agencylọ ọrụ ahụ na-enyocha LRO site na iji teknụzụ ndị sitere na laser kemgbe 2006. E zigara pulses laser mgbe niile n'etiti LOLA na ụlọ ọrụ ohere, mana nke a bụ oge mbụ mmadụ jisiri ike mezuo nkwukọrịta otu ụzọ.

NASA ga-eburu n'uche ikuku ụwa mezie njehie ọ bụla, na-eji otu usoro eji edozi CD na DVD. N'oge a niile LRO gara n'ihu na ọrụ ya kwa ụbọchị, nke gụnyere ịkọwa ọnwa.

Nkwukọrịta laser ga-enwe nnukwu mmetụta na teknụzụ nkwukọrịta n'ọdịnihu

N'ọdịnihu dị anya, nkwukọrịta laser ga-ekwe nnyefe data na bitrates dị elu karịa nkwukọrịta redio, kwuru LOLA onye ọkà mmụta sayensị, David Smith. N'oge na-adịghị anya, a ga-eji teknụzụ dị otú ahụ mee ihe ndabere maka nkwukọrịta redio, kwukwara Smith.
