Ashitey Trebi-Ollenu: The Ghanaian Scientist Investigating Beneath Mars’ Surface

Dr Ashitry Trebi-Ollennu

As a child in Ghana, Dr Ashitey Trebi-Ollenu watched planes take off and was inspired by the possibility of autonomous aircraft.

Now, he’s the innovator robotically deploying and installing landers autonomously on other planets.

Dr Ashitey Trebi-Ollennu is the Product Delivery Manager, for the InSight Mars Mission Instrument Deployment System, Instrument Deployment System operations Team Chief and a technical group lead in the Robotic Manipulation & Sampling group at NASA Jet Propulsion Laboratory, California Institute of Technology, where he has been since 1999.
