? If you're under the age of about 25, it's
possible you've never seen or used one of these: it's an LP record - the
way most people listened to music before music CDs and MP3s came along.
In the 1970s, NASA launched two spacecraft called Voyager 1 and Voyager
2 to explore remote parts of the solar system. Onboard, they were
carrying golden LP records with various soun
ds
recorded on Earth for aliens to listen to and (probably) laugh at....
including greetings in 60 Earth languages and music tracks by Mozart and
Chuck Berry! Now aliens might well like Mozart, but what would they
make of this very primitive way of recording sound? You can just imagine
some green-eyed Martian blob wondering how to fit this thing into his
or her iPod. Interestingly, the Voyager spacecraft are still blasting
through space. In June 2012, NASA revealed that Voyager 1 is close to
leaving our solar system. It now holds the record for the furthest
human-built object from Earth!
