We've got a giant radar in the payload bay, bubbles in the water, and we're ready to learn about somebody's favorite type of lizard. It's time for STS-59!   Errata: Around two minutes into the episode I use the term "frequency" multiple times when "wavelength" is correct. Really, since the wavelength is just the speed of light divided by the frequency if you know one you know the other, but still, I used the wrong term.
