Internet sleuths have uncovered a hidden message left by NASA on the inside of the parachute that landed Perseverance on Mars - it says 'Dare Mighty Things' in binary.
The code was written into the lining of the parachute, made from a custom material crafted in Devon, and kept under wraps until it was deployed on February 18.
Nobody outside a core group within NASA knew what the message was until it was unveiled to the public when the agency shared new images and a video showing the 'seven minutes of terror' landing, including a view of the inside of the parachute.
