ESA’s cubic-metre-sized Proba-V minisatellite will soon end its nearly seven-year global mission to monitor the daily growth of all Earth’s vegetation. As Copernicus Sentinel-3 takes on this task instead, Proba-V will be free to perform experimental monitoring over Europe and Africa – including co-observations with new companion missions.
“There is a precedent for such an arrangement,” adds Roberto, “with predecessor mission Proba-1, launched back in 2001, hosting a hyperspectral camera. Having passed through such a period of orbital darkness it is still observing to this day.”
The next in the series of Proba technology-testing missions will be Proba-3, a double satellite mission to demonstrate precision formation flying while studying the surrounding corona of the Sun, due to fly in 2022.

Proba-V satellite
In the past Proba-V made such lunar acquisitions on a monthly basis. Now the minisatellite will increase them, experimenting with changing frequencies and view angles for the benefit of future Earth-observing missions.
In addition, the plan is to launch in 2021 an additional tiny satellite carrying a single telescope version of the same Vegetation imager aboard Proba-V. This mission is being developed through ESA's General Support Technology Programme, backing advanced technologies for space testing, which also supported the development of Proba-V itself.
