In the 1980s, scientists discovered a gaping hole in Earth's ozone layer, caused by humanmade chemicals. But thanks to the historical Montreal Protocol, the world came together to take bold action to save our planet. Decades later, we can see the steady recovery of the ozone hole. How did we do it? And what does space have to do with it? Join us as we explore the journey of the ozone hole, from its alarming discovery to the incredible strides made to fix it, and how satellites are helping us track its recovery.

Over the last few months, ESA’s Earth Explorer Biomass satellite has been going through a punishing series of tests to make sure that it will survive the unavoidable blasts of noise and shuddering during liftoff. Engineers have now also tested that it will unfold its solar wing in the correct sequence. Coming through all of this with flying colours, Biomass is a few steps closer to its mission in orbit: to deliver completely new information on our precious forests and the carbon they store.

As Perseverance celebrates its second anniversary on Mars, our team is reflecting on the rover's remarkable journey so far. In the past two years, Perseverance has collected 18 Martian samples, traversed over 9 miles, transmitted over 200,000 images to Earth, supported the Ingenuity helicopter with its 42 flights, and much more. Now, after spending nearly 6 weeks creating the Three Forks s
