Earth, and the possibility that we could wreck our environment.
Greetings, fellow sky watchers! As October ends, we have another exciting week in astronomy for you. This week's highlight is a total eclipse of the Moon! On October 27/28 our "nearest astronomical neighbor" will slide quietly into the Earth's dark cone of shadow called the umbra, providing most of us from Europe through North America with an inspiring view - but that's not all. There will also be many other great things to explore this week such as lunar features Tycho, Grimaldi, Langrenus, Mare Crisium and Hercules. We'll locate the 12th brightest star in the sky and do a "double take" as we learn about Albireo. Rich star cluster, M45 is waiting on you to explore with binoculars, Telescopes - or just your eyes and imagination. There's a little history here and a lot of fun. Now it's time to mark your calendars...
Because here's what's up!
Last week, Mark Mortimer reviewed Dennis Wingo's new book, Moonrush - Improving Life on Earth with the Moon's Resources, about the prospects of getting our future materials from space. Well, we had a few more questions for Wingo, about property rights, related projects here on Earth, and the possibility that we could wreck our environment so badly that getting into space is totally out of reach. Read on for this bonus interview with Dennis Wingo.
NASA's Cassini spacecraft will make its first close approach tomorrow to Titan, Saturn's largest moon. The spacecraft will skim within only 1,200 km (745 miles) of the moon's atmosphere, which should allow its radar to penetrate through its thick methane atmosphere and reveal details about its surface. scientists have theories, but they really have no idea exactly what Cassini is going to discover; whether it's covered in ancient craters, or there are ongoing geologic processes that are reshaping its surface continuously. Cassini will also gather data about Huygens' potential landing site when it arrives at the Moon in a couple of months.
