Default NASA New Horizons web site

Saw this on NASAs New Horizons web site -

"What would a human see on Pluto?

An astronaut (Plutonaut?) stepping from their spaceship onto Pluto's surface would quickly notice many unusual qualities of this alien environment ... thousands of stars are visible, even in daytime." (Ref: http://pluto.jhuapl.edu/overview/faqs.php)

Is it just me, or is that, at least, incredibly misleading?

According to http://ask.metafilter.com/23197/Dark...e-edge-of-town, "direct sunlight on Pluto is still a bit brighter than twilight on earth", which surely rules out seeing "thousands" of stars (unless, of course, you take precautions to hide the reflected light from the terrain (plutain?) entering your eyes). Pluto has the advantage of not having any atmosphere to speak of, but the adaptation of the eyes to the ambient light level must surely rule out seeing "thousands" of stars.

The other problem I see with that web site is their insistence on calling Pluto a planet -

"Pluto is the only planet in our solar system, unexplored by space probes".
"Pluto's gravity is weak so that it takes a large amount of fuel to go into orbit around the planet".
" ... making daytime on the distant planet much darker than a cloudy, stormy day here at home".
"Depending on which part of the planet the astronaut landed".
etc.

This is in spite of the fact that the site has evidently been updated since the redefinition of "planet".
