CryoSat still cool at 10
08 April 2020
Today marks 10 years since a Dnepr rocket blasted off from an underground silo in the remote desert steppe of Kazakhstan, launching one of ESA's most remarkable Earth-observing satellites into orbit.
Tucked safely within the rocket fairing, CryoSat had a tough job ahead: to measure variations in the height of Earth's ice and reveal how climate change is affecting the polar regions. Carrying novel technology, this extraordinary mission has led to a wealth of scientific discoveries that go far beyond its primary objectives to measure polar ice. And, even at 10 years old, this incredible mission continues to surpass expectations.
The launch of a satellite is always a time to hold your breath, but CryoSat's liftoff on 8 April 2010 was arguably more tense than most as it came less than five years after the original satellite was lost owing to a rocket malfunction.
So important was the need to understand what was happening to Earth's ice, the decision to rebuild was taken quickly – and thankfully, this day 10 years ago heralded the beginning of a mission that was set to advance polar science like no other.
