“…Real‐time monitoring of the Van Allen Probes dynamic radiation dose and dose rate near the location of sensitive electronics has been reported in the earlier Engineering Radiation Monitor (ERM) and solar monitor results (Maurer et al, , after 260 days; Holmes‐Siedle et al, , after 365 days; and Maurer & Goldsten, , after 971 days).…”

“…The charge monitors can handle large current density (∼3,000 fA/cm 2 ) with sufficient sensitivity (∼0.1 fA/cm 2 ) to characterize quiescent conditions. High time resolution (5 s) monitoring allows detection of rapid changes in flux (Maurer et al, ).…”

The Engineering Radiation Monitor measures dose, dose rate, and charging currents on the Van Allen Probes mission to study the dynamics of Earth's Van Allen radiation belts. Over 5 years, results from this monitor show a variation in dose rates with time, a correlation between the dosimeter and charging current data, and a comparison of cumulative dose to prelaunch modeling. Solar cell degradation monitor patches track the decrease in solar array output as displacement damage accumulates. The Solar Cell Monitor shows~33% cumulative degradation in maximum power after 5.1 years of the mission. The desire to extend the mission to~2,500 days from 800 days created increased requirements for the ionizing radiation hardness of spacecraft and science instrument electronics. We describe the investigations that insured compliance with these enhanced requirements.

“…The mass is 1.5 kg; the power 0.2 watts when operating; the dimensions are 18 X 18 X 6 cm. A detailed description of the ERM, its operation and early results can be found in [7,8,9]. Designed to take the place of a spacecraft balance mass, the ERM contains an array of eight dosimeters and two buried conductive plates.…”

The Van Allen probes team has been successful in monitoring and trending the performance of the mission to date. However, operating two spacecraft in the Van Allen radiation belts poses a number of challenges and requires careful monitoring of spacecraft performance due to the high radiation environment and potential impact on the mostly single string electronics architecture.Spacecraft and instrument telemetry trending is tracked with internal peer reviews conducted twice a year by the operations and engineering teams. On board radiation monitoring sensors are used to evaluate total dose accumulated on board the spacecraft and to assess potential impacts. Single event upsets are tracked and high activity events are logged and analyzed. Anomalous data is compared to radiation and solar event activity to determine if there is correlation. Solar array degradation is monitored in real time using a dedicated monitored solar cell and performance is compared to predicted degradation rates. Examples of the effects of radiation on various subsystems and instruments will be given and the impacts discussed as the Van Allen probes team prepares to take on the challenge of an extended mission of continued operations in the radiation belt.

Cube Satellites (CubeSats) are rapidly increasing in utility and have moved from primarily an education tool to a highly capable platform for scientific research. In-situ (Crew et al., 2016;Li et al., 2013) as well as remote sensing (Mason et al., 2016) measurements from CubeSat platforms have led to significant advances in space sciences. As the number of CubeSats launching into orbit increases rapidly each year (Swartwout, 2018), this platform will continue to serve as a test-bed for innovative technologies and observing constellations (
