My thoughts on mission Voyager

Hi,
as the title suggests I will be talking about the mission Voyager 1 and 2. I never mentioned them in separate post until today. It is also connected with my presentation I had on the contest.


What are those missions anyway?

Those are two space missions that had quests to check out furthest planets of our Solar System. Because of rare occasion, Voyager 2 was able to check out 4 planets (+ Earth).

Right now both Voyager 1 and 2 are still capable of transmitting signal because their battery working on radioactive materials is still ok, it is not much though, not pictures or something like that.

Voyagers are twins.

Both were launched in the year of 1977 and are about 19 billion kilometers away from they Earth.


The thing is that both missions are very cool and they collected lot of data but they also have this “Voyager golden record”. It is record of “The sounds of Earth” which are voices  from various languages and also the plate contains some information on how to play it and where in Universe it was launched from.

I know that this was not the main reason for the mission to be launched but at the same time it was not really well made up.

Above you can see the information on how to play the record. How could anyone in the hell know what is this supposed to do? I mean, how can we know that aliens have similar technology like us and that five pictograms can explain how to use it!

There are also images on this thing! There is image of woman in supermarket, photo of Jupites and so on (you can check it out here).

The left circle explains in binary how fast it should be playing. Than the wave is typical frequency of the sound that should come out and under it is something called “scan triggering” (wut?). The boxes under it represent how the image is made and the circle is the first picture that should appear. The lines represent the position of Sun compared to 14 brightest pulsars out there and the two circles represent two hydrogen atoms.

Though this whole thing seems a bit dumb to me, I at least like that they included piece of uranium so that “alien” can know how long it is flying (via radioactive decay).
