NASA's space probe that is currently at asteroid Bennu and will return a sample in 2023 is called Osiris-REx.
Osiris-REx -- Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer
The words just were strung together characteristics separated by a comma. And "Security?" Really?
NASA's latest Mars Lander is InSight:
InSight -- Interior Exploration using Seismic Investigations, Geodesy and Heat Transport
They conveniently skipped the "E". And it might be a bit of a stretch to say that InSight is engaging in Geodesy; it is investigating Mars' rotation, which is more of an effect of planetary geodesy rather than an aspect of it.
One of my favorites from NASA is the "EPOXI" mission, which is the follow-up mission to NASA's Deep Impact. They re-targeted an old spacecraft that sent a projectile into a comet (the original Deep Impact Mission) so it would flyby yet another comet to observe it. Additionally, a whole separate mission using the same spacecraft used the camera onboard the craft to investigate extrasolar planets. EPOXI itself is not an acronym for the mission, but is a mash-up of two other acronyms EPOch and DIXI
EPOCh is the Extrasolar Planet Observation and Characterization
DIXI is the Deep Impact eXtended Investigation
