What is Proba-1?
Proba-1 is a technology demonstrator turned operational Earth observation mission - ESA's smallest, less than a cubic metre in volume. Proba-1's main instrument is the Compact High Resolution Imaging Spectrometer (CHRIS), acquiring 13 square km scenes at 17 m spatial resolution in 18 user-selected visible and near-infrared wavelengths. This agile satellite can also deliver up to five different viewing angles. Nearly 20,000 environmental science images have been acquired.

About this Mission
The Project for On-Board Autonomy (Proba) was originally a technology demonstration mission of the European Space Agency, started in mid-1998 and funded within the frame of ESA's General Support Technology Programme.
Intended as a one-year mission, Proba-1 has provided data successfully ever since its launch on 22nd Oct 2001. Hosting two Earth Observation instruments CHRIS and HRC, Proba-1 has been managed, since 2004, by ESA's Ground Segment Department within the Directorate of Earth Observation at ESA/ESRIN.
