Source-derived summary

THEOS, also known as Thaichote, 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 funds the program.

THEOS was launched from Dombarovskiy at 06:37 UTC on 1 October 2008, by a Dnepr rocket. The satellite was initially planned for a 2007 launch using the space vehicle Rokot of Eurockot Launch Services . The contract was however canceled when Eurockot faced a parts shortage.

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. The objects have not yet been identified as debris.

Editorial summary

Begin with the source’s own compact description: “THEOS (satellite)” is thai Earth observation satellite launched in 2008. The dossier treats that line as a proposition to test through THEOS, satellite and Thai, not as a finished interpretation.

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current lead gives the account dated anchors—2004, 2008, 2007, 2014—that can be checked directly. The selected authority fields contribute no independent date. For this dossier, THEOS, satellite and Thai is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “thai Earth observation satellite launched in 2008” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Oct 10, 2025. The linked authority identifier is Q2036857. None of the 2 selected statements returned an explicit reference. The first chronological checks are 2004, 2008, 2007 and 2014.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
