Mission Space Public API
Space weather data and atmospheric model API providing solar wind, geomagnetic indices, and models.
⚠️ API Under Construction
This API is currently in development. Endpoints and data formats are subject to change. Production availability coming soon.
Data Overview
- Kp Index: 3-hourly geomagnetic activity (0-9 scale)
- Magnetic Field: Solar wind Bx/By/Bz from DSCOVR L1
- Solar Wind: Speed, density, temperature, pressure from DSCOVR L1
- Proton Flux: Energy channels >0.5-100 MeV from GOES
- X-Ray Flux: GOES classification (A/B/C/M/X-class)
- Satellite Data: POES high-latitude and GOES geostationary measurements
- Events: Coronal mass ejections
- Models: JB2008 and MSIS atmospheric density/temperature calculations
