THEOS, also known as Thaichote,[2][3] is an Earth observation mission of Thailand, developed at EADS Astrium SAS, Toulouse, France. In July 2004, EADS Astrium SAS signed a contract for delivery of THEOS with GISTDA (Geo-Informatics and Space Technology Development Agency) of Bangkok, Thailand. GISTDA is Thailand's leading national organization (i.e., space agency) in the field of space activities and applications. The Thai Ministry of Science and Technology is funding the program.

It was launched from Dombarovskiy at 06:37 GMT on 1 October 2008, by a Dnepr rocket.[1] The launch had been delayed several times after clearance for the flight was revoked by down-range countries.[4]

On 24 March 2014, THEOS captured images showing some 300 objects in close proximity to the suspected crash site of Malaysia Airlines Flight MH370, in the Indian Ocean. The discovery was reported by GISTDA on 27 March 2014.[5] The objects have not yet been identified as debris.
