And my kids can't find their cell phones

NASA's Dawn spacecraft is on track to begin the first extended visit to a large asteroid. After traveling nearly four years and 1.7 billion miles, Dawn is now approximately 48,000 miles away from 330-miles-diameter Vesta, the second largest asteroid in the solar system. When Vesta captures Dawn into its orbit on July 16, there will be approximately 9,900 miles between them. When orbit is achieved, they will be approximately 117 million miles away from Earth. During the initial reconnaissance orbit, at approximately 1,700 miles, the spacecraft will get a broad overview of Vesta with color pictures and data in different wavelengths of reflected light. Dawn then will move even closer, to a low-altitude mapping orbit approximately 120 miles above the surface. Dawn spacecraft launched from Cape Canaveral Air Force Station, Fla., on Sept. 27, 2007. It will continue observations of Vesta until July, 2012, then be moved to observe Ceres, the largest, 590-mile-diameter asteroid, from Feb. to July, 2015.

I found this an amazing report.

And NASA's future is what?

Thanks for the report. I wish more of this type of event were going on.

Things like this should be much more advertised than some of the BS that is covered by the media today. I didn't know anything about this. Thanks for the update...

After reading this I can kinda understand My Willa when she gets mad at me for not ''hitting'' the commode when I go tinkle. She says that if scientist can make a devise that can go that far and be that accurate over that length of time that surely they could invent a ''devise'' to attach to a mans ''thingie'' that would enable him to accurately ''point'' this ''thingie'' at a relatively large object like a commode opening and re leave himself in such a manner that most, if not all of the liquid, would be transferred to the receptacle without any ''dribble'' on the floor.
I told her that I could resolve the problem very simply.
I could just ''tinkle'' in the tub..............OOPS....
She hit me with the commode brush........lol.....

Aint life grand ............

Salute our troops ........

Seajay...What is REALLY amazing in all this, is NASA did all the calculations with one of THESE. Maybe one could help calculate your proper 'angle of dangle' for the correct trajectory. Bob
