Voyager is old, but still can dance!
posted March 14 2011 22:48.17 by Giorgos Lazaridis




You may not be amazed when you read that Voyager managed a 70 degree roll maneuver... But think of this: Try to find one single electronic device that you own, and works flawlessly for the last 33 years without ANY maintenance at all! Not amazed yet? Well, take also into account that Voyager operates in some 400 degrees below zero! And also, do not forget that it was made in the era that Atari was the ultimate gadget of all times!

Last month, Voyager managed a 70-degree roll with the help of its gyroscopes with full success. Last time it had done such a maneuver was back in 1990. The whole operation took about 16 hours to be performed, and another 16 hours to be confirmed. 16 hours? Hmmmmm. A typical communication delay from Mars to Earth varies from 3 to 22 minutes. Now imagine how far is voyager, that takes 16 hours for the radio signal to reach earth (11 billion miles away!)

    • sure Bob. I am talking about Fahrenheit degrees. -400F are actually -240C. Absolute zero is at 0 Kelvin, which is -273.15C (-459.67K).
      The actual temperature in space (according to NASA), is 3 degrees above absolute zero, which is 3 Kelvin, or -454.27 F or -270.15 C. These are the numbers that i should have put instead of "some 400", to be scientifically correct :D...

      Thanks for noticing it and giving me the chance to update.

    • Can you please clarify "some 400 degrees below zero...?. It could not be Celsius, I venture to say. Absolute zero is, if I remember correctly, -274 degrees Celsius. So, is it Kelvin or Fahrenheit?
