Launched on May 7, 2013, the European Space Agency’s minisatellite Proba-V monitors Earth’s plants, covering the entire planet every two days. At the end of the month, after a year in orbit, this little bundle of sensors will be taking over the job of a series of satellites that have been tracking the health of the planet’s vegetation for 16 years. The ESA’s Spot-4 satellite stopped working in 2013, and Spot-5 is on its last legs.

Not only is Proba-V the size of a washing machine, it looks a little like one too. The minisatellite has a huge, 1,400-mile-wide field of view — enough to cover most continents in a single shot. In order to get the best information about Earth’s flora, the satellite’s Vegetation instrument detects light in the blue, red, near-infrared and mid-infrared wavebands. The instrument has a 1,150-foot resolution.
Accounting for cloud cover, the satellite collects enough data for a nearly cloud-free global map every 10 days.
In addition to keeping track of vegetation growth, the little satellite’s data makes beautiful images. Here are some of its best views of Earth from its first year in orbit.
