Nasa is preparing its Mars orbiters for a ‘duck and cover’ manoeuvre hours before comet Siding Spring is due to hurtle by Mars, in a once-in-a-million years event. Siding Spring comes from the Oort Cloud - material left over from the formation of the solar system. Astronomers say the comet has traveled many billions of miles to reach Mars. Siding Springs nucleus will miss Mars by about 87,000 miles on Sunday, flying by at a speed of about 126,000 miles per hour. independent.co.uk/news/science/siding-spring-how-to-watch-comets-encounter-with-mars-live-9803981.html
