Well, that's still more likely than an American saying "There's no substitute for cubic centimeters."

"Yes... yes. This is a fertile land, and we will thrive. We will rule over all this land, and we will call it... This Land."
And when it arrives, you should scan it, so that you can archive an electronic copy as a backup. That way, if you ever need to replace it, you can just 3D print the whole thing.
The spacecraft is powered by a radioisotope thermoelectic generator (RTG), but that's not a reactor. The power comes from heat produced by the decay of Plutonium, but there is no sustained nuclear chain reaction involved.
Yes, it is.
I'm pretty sure the color movie is made of MVIC images. LORRI doesn't do color, but has much higher resolution. The LORRI images (and this movie) can all be found here.
Ferengi? Don't compare us to those socialists!
I really liked him as Death in the animated adaptations of the Discworld novels Soul Music and Wyrd Sisters. He could actually speak in all caps.
Given that it's in a 375-mile orbit, Hubble was also (and still is) a pretty lousy paperweight.
FROM THE OUTSIDE, IT'S BLUE.
(Yes, that needs to be in all caps.)
Tidal dissipation occurs when the tidal forces vary with time, generally due to the orbit of the secondary being eccentric. That brings it alternately closer to and farther from the primary, stretching and squeezing the interior.
However, the orbit of Charon about Pluto is circular (Buie et al., 2012), so the tidal bulge is constant. There's no time-varying deformation and no dissipation.
The solar wind never gets anywhere near Jupiter's atmosphere. Jupiter has an absurdly strong magnetic field. The magnetopause is between 50 about 100 Jupiter radii from the planet, and the solar wind is deflected around it (Khurana et al., 2004). The jovian aurorae are powered by currents entirely within the magnetosphere (Jupiter's rotation and Io's plasma).
So, no water, no salt.
I highly recommend Good Omens, co-authored with Neil Gaiman.
