NASA site mentions following facts about Voyager.
Did you know that the record is a 30-cm gold-plated copper disc? Together with a needle and playing instructions, it is mounted on the body casing and on it are recorded natural Earth sounds, 90 min of music, 115 pictures, and greetings in 60 languages.
Voyager 1 will remain within the confines of the solar system until it emerges from the Oort cloud in another 14,000 to 28,000 years
Thinking about the time span 14,000+ years to go just to get out from Oort cloud, it would take millions of years to reach another solar system.
- Aren't we endangering our future generations by sending out such a record to unknown aliens?
- Knowing that these crafts will take thousands of years just to get out of solar system these golden records concept seems like a publicity stunt by someone at NASA. What was the real need for this?
