| Oneliner |
Studies dynamic changes in Earth's neutral/ionosphere density in the ~140 km - 290 km altitude region. |
| Description |
Studies dynamic changes in Earth's neutral/ionosphere density in the ~140 km - 290 km altitude region. The wide spatial and temporal distribution of the data provided by DAILI over the course of its mission will improve the accuracy of operational models for both the neutral density and the ionosphere, and will help further the study of wave propagation and transport processes in the lower thermosphere. |
| Results |
Marked as Failure in the NASA SmallSat/CubeSat Fleet Missions Database. DAILI operated for 5 months; Data was successfully collected; all technical developments worked as designed especially the new and unique earthshade; data was collected of this phenomenology, including during two geomagnetic storms; the data from the storms showed unusual atmospheric density changes that currently the subject of continued scientific investigation; a bus RW failure stopped the mission. |
| Failure cause | Reaction wheel failure after 5 months. |
