On 16 February an ESA satellite called Sentinel-3 will blast up into orbit around Earth! Sentinel-3 is the latest in a fleet of advanced satellites whose mission is to study our planet\u2019s land, oceans, and atmosphere.<\/p>\n<\/div>\n

Sentinel-3\u2019s focus will be our oceans. Covering 70% of the planet, monitoring oceans is a way for us to check how healthy the Earth is. What happens in the seas impacts us no matter where we live. Our planet\u2019s water is an important resource, and one we need to protect.<\/p>\n

Sentinel-3 will orbit over 800km above Earth\u2019s surface \u2013 that\u2019s even further from the Earth than the International Space Station, which orbits our planet at around 400 km. From this vantage point the satellite will measure the temperature, colour, and height of the sea surface, as well as the thickness of sea ice. These measurements are really important because we can use them to track how the sea level is changing, how much pollution is present, and how healthy sea life is.<\/p>\n

When not monitoring the ocean, Sentinel-3 will help its fellow satellite Sentinel-2 by watching the Earth\u2019s land. It will measure the heights of lakes and rivers, and even track dangerous wildfires.<\/p>\n

There are already two Sentinel satellites in orbit, and four more are planned after Sentinel-3. Each satellite will work for at least seven years. Mission scientists are hopeful that they will work for even longer though, and have supplied enough fuel to keep the satellites going for 12 years of constant operation!<\/p>\n

Ciekawostka:<\/b> The rocket that will take Sentinel-3 into orbit is a modified SS-19 intercontinental ballistic missile. This was originally designed as a weapon of war, but has been converted to peaceful purposes. This is very fitting given Sentinel-3\u2019s mission to protect Earth!<\/p>","protected":false},"excerpt":{"rendered":"
