British planetary scientist Colin Pillinger, best known for his 2003 attempt to land a spacecraft on Mars, has died aged 70, his family have said.

Prof Pillinger was at his home in Cambridge when he suffered a brain haemorrhage and fell into a deep coma.

His family said he later died at Addenbrooke's Hospital without regaining consciousness.

His death was "devastating and unbelievable", they said in a statement.
