Space is big. 
Space is dark.
It's hard to find
a place to park.

We'll discuss any of the topics that I listed in Tuesday's notes ... or anything else that seems related. ;)

• Kepler v Newton ... with code & graphics ;)
• wikipedia: non-rocket space launch ... mass driver, space elevator, and all that.
• if the moon were one pixel ... the solar system to scale
• wikipedia: geosynchronous orbit
• stuffin.space - lots of satellites ...
