INTERSTELLAR surprises are in store, say managers at the Eden Project, as its Journey into Space programme reaches its final weekend (September 2 to 3).

A supersize Eden astronaut who has been touring Cornwall over the summer is set to make a special appearance by the Biomes on Saturday and Sunday.

Prizes will be given out for the best pictures taken of the giant space traveller.

There is a chance to go on a Mission to Mars with Maddie Moate, children’s presenter of Cbeebies Do You Know? and YouTuber, who is doing two shows a day this weekend featuring rockets, robotics and the smells of space.

Part of the Meet the Experts programme, Maddie’s talks are included in admission and are first come first served.
