PEP-8 does cover this (at least partially):
Note: When using abbreviations in CapWords, capitalize all the letters of the abbreviation. Thus
HTTPServerErroris better thanHttpServerError.
Which I would read to mean that NASAJPL() is the recommended name according to PEP-8.
Personally I’d find NasaJpl() the easiest to scan since the upper case letters easily mark word boundaries and give the name a distinctive shape.
