NASA sends a "message in a bottle" to the moon of Jupiter - including one word in Hebrew. The "Clipper Europa" probe will be launched later this year, and the preparations are in full swing.

Europa is the sixth moon of the planet Jupiter and the second of the Galilean moons. Its diameter is about 3,000 km, slightly smaller than the Earth's moon. The existence of such an ocean raises the possibility of life on Europa, making it one of the most fascinating destinations for space exploration.
