Mindwebs: The Sentinel

The Sentinel

This is a Clarke, one originally published in 1948; some hint of the age may be seen in the hopelessly outdated geology of the Moon. This story was the starting point for the movie and the book 2001: A Space Odyssey, although only the barest details survived the transformation.

One quibble: when the narrator frets (spoilers)

that humans will not have long to wait until the aliens turn up to see what broke their machine, I think he makes two errors:

The first is there's no evidence the aliens are in fact interested in intelligent life. That's just an idea that comes to the narrator and there is, I think, evidence he and the other astronauts are obsessed with finding intelligent life.

Secondly, these are beings who carry out plans that apparently last billions of years. What is "not long" for them may be very long for us.

I think "planetary science" is winning these days.

But wouldn't "planetary science" cover more than "planetary geology" -- meteorology, oceanography, ecology all fit the label too.

That is exactly why it's so popular: it covers the astronomical aspects and the geological aspects of studying solar-system bodies, and the atmospheres, chemistry, etc. can be thrown in, too.

Many universities group this stuff under the even more vague "space science." Often the names are expressed as departments of "Earth and Space Sciences" or "Earth and Planetary Science."

Strictly speaking, any term such as "areology" "selenology" also have the same problem as "planetary science", as they just mean "[astronomical body], the study of", which obviously incorporates everything about the body in question and not just the lithology of it.

However, "Planetary Science" as a term for this sort of study has the additional problem that it doesn't actually apply to the study of the lithology of fakey non-planets like Pluto or Ceres, nor moons like The Moon or Titan, as none of those are planets by any currently accepted scientific standard.

...it doesn't actually apply to the study of the lithology of fakey non-planets like Pluto or Ceres...

If this is your objection, I'll point out that "astronomy" never has been limited to the study of stars.

Yep, Planetary Scientist is usually used for people working on extraterrestrial bodies (and connected stuff like impacts).
