The JPL Ethics Office

Commercial and Political Endorsements

An endorsement or testimonial is a written or spoken statement, extolling the virtue of a thing, product or service.


JPL's image and success in competing for public funding requires a clear perception of impartiality in the dealings with the general and business public. Therefore, JPL employees shall refrain from any action that could reasonably be perceived or implied as an endorsement or official preference by the Laboratory, Caltech, or NASA. Prohibited actions include written, oral, and electronic correspondence, either from the Laboratory or with any Laboratory identification.
