Saturn transiting the Sun as seen from Neptune in 2061, and David Letterman's first Shuttle launch

Monday, May 24, 2010

Crazy cat day here is finally over (MB's hurt toe is a bit gangrenous but the vets think they should be able to keep him from losing half of it by keeping him there for a week and Windy is back to normal after freaking out at the new cat in the apartment), so let's wrap it up with a quick two videos to share.

The first is this one, showing Saturn transiting the Sun in 2061 as seen from Neptune. Transits are opportunities that you never want to miss since they're free data about the atmospheric makeup of a planet or body as the Sun begins to become obscured by the atmosphere first, but not so valuable that one would want to send a probe to somewhere like Neptune just because of it. But if we have a probe around Neptune at the time, this is what we'll see:

A much sooner transit is the 2012 transit of Venus, as seen from Earth.

And in This Week in Space for this week (which I haven't watched yet), the most interesting parts seem to be David Letterman recounting his first Shuttle launch watched in person, and an interview with Elon Musk.
