Yes and no. I think space exploration is worth the money and worth pursuing, but I'm not sure in an economy and with a government that is so loose with the purse strings that now is the time to explore Mars and some of the other expendatures we're floating out there. Our politicians (regardless of party) have the financial sense of a pre-teen. Its kinda like having irresponsible kids, giving them an allowance, watching them blow it but leaving the credit card out to spend more on fun stuff like remote control cars and planes when their money is gone. Makes no sense.
NASA's budget hit is right around .5% For every $1 spent on on NASA our government spends $98 on social programs. One B-2 bomber costs 3x more than the price tag of the New Horizons mission to Pluto. The London Olympics cost just about $15 billion dollars. In 9 years the Mars Curiosity rover has cost roughly $2.5 billion. The interest on our national debt is annually 24 times the cost of the budget of NASA.
I think its worth it.
There would be little or no sound, as we experience it, in space. What we call sound is how the association cortex of our temporal lobes interpret & make sense of wavelengths from about 20hz to 20khz (if you have incredible hearing)that hit our ear drums and then pass through our auditory system. I don't know how much is going on in space in that narrow frequency range though they do sometimes take much higher frequencies and divide them down to the range of human hearing.

What the prof is telling you is that sound doesn't exist in space. Sound is dependent on the vibration of molecules. In the vacuum of space, there are none so no sound. What is recorded is most likely the electronic interference that the magnetic fields pick up. Possibly creation of electromagnetic energy in the radiofrequency range, but not raw sound.
