NASA’s Enhanced Tandem Beacon Experiment (E-TBEx) is made up of twin cube satellites. They have successfully deployed from the rocket at 3:08 a.m. and 3:13 a.m. EDT. E-TBEx will measure the disruption of radio signals from natural-forming bubbles in the Earth’s upper atmosphere. Understanding these disruptions and how to overcome them ultimately will improve the reliability of radio and GPS signals, which we rely on every day.
