For almost five years, the Copernicus Sentinel 1-B satellite monitored and photographed our planet from above.

But 8 months ago, the satellite stopped working properly.

After trying and failing to fix this set of eyes in the sky, the European Space Agency announced that the satellite has been shut down.

Sentinel-1B stopped transmitting data back to Earth in 2021.

Meanwhile, its identical counterpart, Sentinel-1A, still collects data for maps and images of the planet.

Sentinel-1B will soon be replaced by a new satellite, Sentinel-1C.

Before Sentinel-1B stopped transmitting, it spent years mapping the globe using radar alongside Sentinel-1A.

The pair captured views of the Earth quite distinct from satellites that see in the visual spectrum.

Radar vision let the satellites peer through clouds to observe changing croplands, oil spills, drifting icebergs, and more.

Here are 9 stunning images captured during Sentinel-1B’s prime years:

9. The Barents Sea and a bit of the Svalbard archipelago were among first targets imaged by Sentinel-1B after its launch in 2016.

8. In 2018, Sentinel 1-B studied Northeast Ethiopia to produce this false-color image. Yellow represents higher elevations, while blue present are lower lands.

7. The mighty Amazon River, captured by the Sentinel-1 satellites in 2019.

6. When the Ever Given cargo ship got stuck in the Suez Canal in March 2021, the Sentinel-1 satellites spotted the traffic jam from space.

5. Oil spills are sometimes large enough to see from space. Here’s one spreading in the Mediterranean Sea in 2018 over 37 miles long.

4. The satellites began imaging the Mackenzie River in Canada in 2019, and completed this image in 2020.

3. A huge iceberg broke off Antarctica’s Brunt Ice Shelf in 2021. The satellites captured it drifting over nine days in August.

2. The satellites also watched croplands worldwide to spot changes over time.

In this timelapse, they show a year’s worth of changes in Seville, Spain through 2017.

1. Currents in the Bering Strait, captured in 2019, show less ice during winter than the region typically expects.
