Collision Course? A Comet Heads for Mars

yeah, I saw it too -- but it's only a 1 in 2000 chance. It sounded so much more interesting than that. :)

Martian auroras sounded pretty interesting ... don't forget to vote in the photo of the year contest (see previous link) -- it's down to the final four ...

Come Fly With the Newest Landsat

//earthobservatory.nasa.gov/Features/LDCMLongSwath/?src=eoa-features

Satellites don't take videos; they capture still images. But in a new mosaic, 56 stills have been stitched together to present a seamless video flyover of what LDCM saw one day in April 2013.

NASA just gave a grant to an inventor that has invented a food replicator. (a 3d printer that can print food)

For some reason I've always had trouble making a decent pie crust -- maybe this is the answer!

I'm guessing (if it's real) it has to do with a potential Mars mission, with a goal of assembling shelf-stable ingredients into something resembling a food item more appetizing than paste ... and anyway, it seems like a tastier use for a printer than making a handgun ... ;-)

What's more impressive (to me) is the progress being made in getting those printers to use cells to print transplantable organs.

Or a glass of cold beer ...

I think I heard that pizza (an almost 2-D food anyway) might be the first target ...

Oooh!! Thanks for the reminder! I have to go look up the time. I think I put it on my calendar...

Ok -- 5:40PM eastern time.

It should be a speed challenge!! 24 hour speed challenge, and your camera time must fall in the 15 minute window where Cassini will be photographing you!

Thanks for keeping this thread current, Gen. Do you think ordinary binoculars will be enough to see Saturn?

If you can hold them steady enough, binoculars may resolve Saturn to a small (flattened) disk, but I don't think you can see the ring structure without a small telescope. At the time of the photo-op, Saturn will still be lost in daylight (near the eastern horizon) from North America, and so not visible at all for several more hours.
