Title: Week 2 Discussion
Course: ASTRON103: The Evolving Universe: Stars, Galaxies, and Cosmology (001) DHH SU18 > Section: Week 2

There are currently around 1,100 artificial satellites in orbit around the Earth. In this discussion, we want you to address the following general questions:

- What are the various purposes of these satellites?
- Which satellites benefit you, personally, here on Earth — and how?
- What are some of the oldest satellites still in orbit?
- What new satellites have space industries, such as Space X, recently launched? What is their purpose?
- How much of a problem is "space junk", and what steps might be taken to reduce or eliminate it?

Note: You must make your own, original response first in order to see other students responses. You can then comment on various responses throughout the week.
