It's amazing the physics behind space travel. Most don't understand it. I have found it amazing since the mid 60's when they actually taught us about it in grade school. We also were herded into the gymnasium to watch Apollo launches and splash down events. It was a huge deal.
Looks like this latest comet craft is ultimately a failure

Quite a Remarkable Achievement imo...
I watched a special about it on TV late last nite on the Science channel....The group responsible for the mission were giddy all over the place..

Seen lots and lots of $$$ wasted in several ventures of late. I'm an old astronomy buff from my childhood years, still own my first telescope and a newer more expensive model with a 9 inch mirror.
My views have shifted a lot however from spending money in space vs. here on earth. That is if the money is properly appropriated of course.
I'm not so sure anymore that whatever technology we gather from space will be processed and used in time to make any difference here on Earth at the rate we're going.

I don't know what they are celebrating. At least not now. It's dead. Ten years down the drain after a few days of pictures

If you read the article that DJofSD posted, it mentions that, "The probe managed to complete over 80% of its planned primary science campaign on the surface", before falling silent. And there's a chance it might reactivate later as it nears the sun.
Just because things haven't gone perfectly doesn't mean it's a failure.

They are massaging the truth in saying that. The reality is that the meaty experiments that prove out the mission's value did NOT get completed.

Comet Ison -- no mas!
http://www.esa.int/spaceinimages/Ima..._disintegrates
Quote:
Comet ISON appeared to survive the close approach, emerging on the other side of the Sun. Some still hoped for a bright display in the night skies. But they were to be disappointed. Quickly, the comet began to disappear. A recent analysis of SOHO data showed that the nucleus had indeed disintegrated just before closest approach to the Sun. Nothing appreciable was left of it, just a lot of dust and vapour.

Oh well.

Orion is a waste of money. And just to be clear, I am in favor of manned space exploration.

you guys are a tough crowd. they hit that thing after a 10 year flight. If nothing else their planning and landing skills leave no doubt.

Have you ever noticed that those who do not have a pot to piss in nor a window to throw it out of always seem to know how to handle the money of those who do.

Fix things on Earth and return to space later. The money being spent/wasted should be used to try and right the ship here. The world is a major mess !!
