• After testing NASA018 for one week, reported battery voltage was significantly lower than normal. Paul and I decided to switch the black box with NASA019's to isolate whether the issue lies in the solar panel or the circuitry. NASA019 will be located on the Wallops Island test site (37.93706, -75.47349) until troubleshooting has been resolved.
