Discovery of Pluto
Pluto is so far away, and has never been explored. Questions to answer about Pluto include the following:
- What are the geologic features of the surface? (pictures of the surface)
- If there are bare spots, what minerals can be found there?
- What is the nature of the atmosphere?
- Are there clouds in the atmosphere?
- What is the character of the winds?
- Is the interior of the planet active?
- What is the temperature of the planet?
and about Charon
- Is there an atmosphere?
- Is there a magnetic field?
Since Pluto's atmosphere should disappear by the year 2000, as it crosses the orbit of Neptune on its 248 year journey around the sun, the time to explore Pluto is now.
