The European Space Agency (ESA) is watching the skies on Wednesday, with European Remote Sensing satellite tv for pc ERS-2 due to descend to Earth on February 21.

The ERS-2 was launched in 1995, following on from its sister satellite tv for pc, ERS-1, which had been launched 4 years earlier.

At their time of launch, the 2 ERS satellites have been essentially the most refined Earth remark satellites ever developed.

In 2011, the ESA retired ERS-2 and started the method of deorbiting.

After 13 years of orbital decay, primarily pushed by photo voltaic exercise, the satellite tv for pc will naturally re-enter Earth’s environment.

During re-entry, the satellite tv for pc will break up into items.

Most of the ERS-2 will deplete on re-entry, however the ESA continues to be monitoring its landfall, which is predicted to happen someplace over the east coast of central Africa.

Any items that survive making landfall shall be unfold out over a floor observe on common lots of of kilometres lengthy and some tens of kilometres vast, so the related dangers are deemed very low.

According to knowledge acquired on February 20, the ESA’s Space Debris Office predicts the ERS-2 satellite tv for pc re-entry will happen round 15:32 GMT.

The ESA’s Space Debris Office did warn their prediction could also be out by roughly 4 and a half hours earlier than or after that point thanks to the affect of unpredictable photo voltaic exercise, which impacts the density of Earth’s environment and, due to this fact, the drag skilled by the satellite tv for pc.

Throughout its 16-year working life, the ERS-2 returned a wealth of data that revolutionised our perspective of Earth and understanding of local weather change.

It collected knowledge on Earth’s diminishing polar ice, altering land surfaces, rising sea ranges, warming oceans, and atmospheric chemistry.

In addition, the ERS-2 was known as upon to monitor pure disasters, equivalent to extreme floods and earthquakes, in distant components of the world.
