The Curiosity is not just a pre-programed robot but is Man’s first representative on the red planet and, on the assumption that there could be intelligent life on the red planet, NASA has set in motion various methods to pass on messages of goodwill to the inhabitants, if any.
One of these is the words JPL – the acronym of Jet Propulsion Laboratory.
These three letters are embedded in the tyres of Curiosity in Morse Code via holes in the tyres and, whenever the Mars rover moves it leaves clear impressions of JPL on the Martian soil.
This has been reported in dailymail.co.uk of dated 24th of August 2012.
The sundial on Curiosity has the words ‘Mars’ written in 16 languages. Also, engraved on it are the words ‘To Mars, To Explore’.
There is also a chip onboard Curiosity which contains 1.24-million names of persons who had been interested in the project – these names had been received through on-line submissions.
Apart from these there is also a list of 20,000 visitors to the JPL and the Kennedy Space Center.
All these names have been etched on silicon chips using an electron-beam microscope and stored on the rover.
