Astronomy Picture of the Day -- MESSENGER's First Day
NASA ^ | October 08, 2011 | (see photo credit)

Posted on 10/08/2011 8:06:16 AM PDT by SunkenCiv

Explanation: One solar day on a planet is the length of time from noon to noon. A solar day lasts 24 hours on planet Earth. On Mercury a solar day is about 176 Earth days long. And during its first Mercury solar day in orbit the MESSENGER spacecraft has imaged nearly the entire surface of the innermost planet to generate a global monochrome map at 250 meters per pixel resolution and a 1 kilometer per pixel resolution color map. Examples of the maps, mosaics constructed from thousands of images made under uniform lighting conditions, are shown (monochrome at left), both centered along the planet's 75 degrees East longitude meridian. The MESSENGER spacecraft's second Mercury solar day will likely include more high resolution targeted observations of the planet's surface features. (Editor's note: Due to Mercury's 3:2 spin-orbit resonance, a Mercury solar day is 2 Mercury years long.)

:’) What will happen is, a startup company will get $600 million to build the timeshares, build one, and be unable to account for the rest of the money. Zero’s fault.

As long as it’s used there, I’m okay with that. :’)

If there were something that could be made into fuel using electricity on the Moon, and delivered in the same way as the titanium, it might even be an export. :’)

Whoops. This made much more sense when I thought I was in a different topic. [blush]

That’s not a Buick.

The car (especially the grill) reminded me of the illustration of the car on the cover of "From a Buick 8" by Stephen King.
