The US government in the past has used its satellite network to identify heat signatures linked to exploding aircraft but in this case, nothing was found, according to US officials, who spoke on condition of anonymity.
The absence of evidence of any mid-air explosion has added to the mystery surrounding the fate of Malaysia Airlines flight MH370, which disappeared at about 1730 GMT Friday after taking off from Kuala Lumpur bound for Beijing.
NBC News first reported the lack of satellite results.
