Bbc Inside Science

The Cassini-Huygens mission has been monumental for science. For thirteen years the probe has gathered data on Saturn, revealing more about the gas giant than we have ever known before. But now, Cassini is running out of fuel. Adam Rutherford talks to Professor Michele Dougherty of Imperial College about the plans for Cassini's spectacular end, which will be to burn up in Saturn's atmosphere later this year. The descent begins this week and Cassini will collect exciting new data until the end. Next week, Theresa May will unveil her plans to kerb air pollution and it is believed that some diesel drivers could be paid up to £2,000 to trade in their vehicles. Diesel cars emit nitrogen oxides - a pollutant that has been linked to nearly 12,000 UK deaths in 2013. This is the second highest in Europe after Italy. However, this isn't the first scrappage scheme to be brought in. Philippa Oldham from the Institution of Mechanical Engineers and Adam discuss the merits and pitfalls of an initiative like this.
