Question 2:
What role did the Apollo missions play in the exploration of the Moon?

The Apollo astronauts returned Moon rocks to Earth. Over the past 30 years, scientists have studied these rocks to learn about the Moon. Some of these rocks contain titanium oxides. These oxides can be used to produce oxygen gas.

Scientists used the Hubble Space Telescope to study the ultraviolet (UV) light reflected from minerals at the Apollo landing sites where these rocks were found. Scientists compared the UV light from the Apollo landing sites with the UV light from other areas of the Moon. If the light from all of these areas is the same, then the same minerals are most likely present in each region.
