Hmm,
the cosmic exposure ages of iron meteorites are much much higher than these
of the HEDs.
So that I as layman wouldn't think, that they stem from the same impact
event/parent body.
(And anyway the iron meteorites stem from a variety of parent bodies, see
the different types)

Betreff: [meteorite-list] Irons from Vesta?

An bit of an interesting article on Space.com come about Dawn arriving at
Vesta entitled "NASA Gears Up for Big Asteroid Encounter"

What caught my eye was in the comments section where montylc2001 wrote:

 "my prediction: we will find that Vesta has been shattered by an impact.
The "mountain" inside the large crater at the south pole is actually Vesta's
exposed iron core, Vesta will be tagged as the source for the rare
iron/nickel meteorites that fall to Earth....."

No doubt this has already been proposed, but anyone care to agree or
disagree?
