PROBA (Project for On-Board Autonomy), renamed PROBA-1, is a Belgian
visible light at 5 m resolution.[5]
With an initial lifetime of one to two years, the satellite celebrated its 20th year of operations in 2021.ERS-2 as ESA's longest operated Earth observation mission of all time.[6] ESA aims to deorbit the satellite through the ClearSpace-1 mission in 2026.[7]
Series of satellites
PROBA is also the name of the series of satellites starting with PROBA-1. The name is also used to refer to the bus of the satellites.
The second satellite in the PROBA series,
SMOS
satellite.
The third satellite to be launched was PROBA-V (PROBA-Vegetation), on 7 May 2013.
The fourth satelite in the program is the formation flying demonstration mission PROBA-3 launched on 5 December 2024.[8]
