NASA is sending a 'message in a bottle' towards Jupiter. Here's how you can add your name to it

The US National Aeronautics and Space Administration (NASA) is getting ready to launch a spacecraft to Europa, one of Jupiter's many moons, next October. 

It's far from a passenger ship, so you can't buy a seat aboard but you can have your name in it — for free. 

Aboard the spacecraft will be a microchip bearing a poem by US Poet Laureate Ada Limón.
