From Earth a message in 103 languages for a moon of Jupiter - Space and Astronomy. The message, a triangular tantalum plate 18 centimeters long and just one millimeter thick, is destined for NASA's Europa Clipper mission, scheduled to launch in October 2024.
The plaque will be affixed to the outside of the probe, which is expected to arrive in Europa's orbit in April 2030. The messages, transcribed as a wave trace, also contain the representation of the spectroscopic signature of water.
