Provide in-situ measurements of plasma density, 3D ion drift, as well as ion and neutral composition.


Study density irregularities in the mid and low-latitude ionosphere. Ion-Neutral Mass Spectrometer, or INMS — the world’s smallest mass spectrometer. Gridded Retarding Ion Drift Sensor.

petitSat is a GSFC 6U CubeSat led by Principal Investigator Dr. Jeffrey Klenzing. The mission is funded by the NASA Science Mission Directorate Heliophysics Division. It is a collaboration that includes Utah State University, Virginia Polytechnic Institute and State University, and Boston University.

petitSat will also be incorporating a technology demonstration of an impulse control system utilizing ion thrusters that was developed internally at GSFC. This demonstration will be conducted once the mission's science objectives have been met.


Marked as Failure in the NASA SmallSat/CubeSat Fleet Missions Database.
