TBEx A, B (Helio 3)

TBEx [SRI]

The TBEx (Tandem Beacon Experiment) will consist of a tandem pair of 3U CubeSat , each carrying tri-frequency radio beacons, in near-identical, low-inclination orbits, and a cluster of diagnostic sensors on five islands in the Central Pacific sector.

TBEx will address a scientific challenge in 2012 NRC Decadal Survey: Understand how forcing from lower atmosphere acts through plasma-neutral coupling processes to give rise to local, regional, and global-scale structures and dynamics in the atmosphere-ionosphere-magnetosphere system. It will monitor the response of bottomside F-layer to wavelike disturbances from below, with sampling intervals less than orbital period, and the development of equatorial plasma structure, including equatorial plasma bubbles (EPBs). The TBEx mission is expected to provide a better understanding of the physics that controls the day-to-day variability in development of EPBs (space weather).

It was selected in 2014 by NASA as part of the Science Mission Directorate's Cubesat Initiative. TBEx was selected in 2015 by NASA to be launched as part of the ELaNa program.
