NIAC Award: Gravity Observation and Dark Energy Detection Explorer

Illustration of the proposed mission concept – a tetrahedral constellation of spacecraft carrying atomic drag-free reference sensors is flying in the Solar system through special regions of interest. Differential force measurements are performed among all pairs of spacecraft to detection non-zero trace value of the local field force gradient tensor. A detection of a non-zero trace, and its modulations through space, signifies the existence of new force field of dark energy as a scalar field and shines light on the nature of dark energy.

We propose further develop and mature the mission concept for direct detection of dark energy, the cause of the accelerating expansion of the universe, using the solar system as a laboratory.
