Question 7
What type of mission collects information about multiple planets?
Sample returns.
Rovers.
Flybys.
Atmospheric probes.
Question 8
Why are neutrinos so difficult to detect?
There are very few of them, so collecting enough to study takes a long time.
They are theoretical and may not exist.
They move so fast they pass right through the telescope.
They don't interact strongly with matter, so they will not cause a reaction on a CCD imager.
