NASA's Dawn Defines Vesta's Role in Solar System History

During a NASA Television Science briefing, scientists discussed the findings of the first global analysis of the giant asteroid Vesta by NASA's Dawn spacecraft. The Dawn mission has confirmed Vesta's status as a special fossil of the early solar system and revealed a more varied, diverse world than originally thought. Dawn has shown Vesta is the only known intact, layered planetary building block with an iron core surviving from the earliest days of the solar system. It therefore more closely resembles a small planet or Earth's moon, not another asteroid.

Very interesting. Thank you so much for doing these briefings!

This is an awesome video; speaking of asteroids being a popular subject, I am looking forward to Planetary Resources and how it contributes to our knowledge in aerospace technology as well as affecting our economy.

Ah, I too fell asleep, it's very late, but then I go back to where I fell asleep and replay the parts I missed :-)

Actually, this is an excellent presentation.

Short answer: No.

Slightly longer answer: Objects large enough to behave in the classical manner we're used to interact mostly via magneto-repulsive forces and gravity rather than electric and magnetic forces, nor do they possess properties like spatial/timelike indeterminacy, the ability to quantum tunnel, quantization, "spin" as used by quantum theory, or entanglement.

It's tempting to think there are similarities because of the false resemblance of the Bohr atom model to the solar system.

thank you N.A.S.A. for the up date of the DAWN mission :) Nicole

I;m also waiting.I;m trying to stay awake, a black screen, nasa needs to present, what they advertise, better, keep things interesting, and keep the public onlooker interested.

As are most celestial bodies, the celestial human, some riding horses are seen and a biological flight craft was noticed a s pleasant surprise. You were very good about discussing everything except that which we would like to hear about. Boring, but good graphics. Most celestials have a tendancy to inhabit much smaller bodies found in our solar system than is Vesta's size.

If it was going to hit us, they would never tell us anyway

Man, you gotta cut down on the punctuation :-)

[Tass]

NASA, you really need to work on your presentation.
You managed to take a very interesting topic and almost made me fall asleep two times.

These Pressconferences have to go. seriously!
you can do better.

[dennisarnold]

Wake your cat up, maybe, something will, show up!.

[Adexter]

You have had pieces of Vesta for over 10 years now. Where is the absolute proof of that.

[LordSlag]

You are ignoring my caveat: I SPECIFICALLY said "..."spin" as used by quantum theory...". That sort of spin does NOT refer to angular momentum possessed by subatomic particles. I can tell by your post and high density of misused terms that you don't know anything about science, or what you're talking about....AT ALL. Gravity is not radiation, in any scientific sense of that word. The Archimedean Spiral has nothing to do with subatomic particles and the Bohr model doesn't describe nature.

That will be u two trust and believed 4:47 4:48 4:49
