Possible Meteorite Imaged By Opportunity Rover 82
Matt_dk writes "The Opportunity rover has eyed an odd-shaped, dark rock, about 0.6 meters (2 feet) across on the surface of Mars, which may be a meteorite. The team spotted the rock called 'Block Island,' on July 18, 2009, in the opposite direction from which it was driving. The rover then backtracked some 250 meters (820 feet) to study it closer. Scientists will be testing the rock with the alpha particle X-ray spectrometer to get composition measurements and to confirm if indeed it is a meteorite."

Less than you'd think - the biggest damage is not caused by the impact, but by the supersonic shock wave of superheated air preceding the meteor. In a thin atmosphere like Mars, there's a much less pronounced shock wave.

Well, in the picture there's no crater at all. The thing is sitting on the surface. That's certainly "less than I'd think".

Conservation of energy. Less atmosphere, less shock wave; greater velocity and impact force.

No, the moon has virtually no atmosphere unlike Mars which has a thin wind, causing erosive effects. The moon is like a museum until something hits it.
At which point it continues to be a museum, just with a hole in it.

What!?!?! Do you have any technical qualifications to make that statement? Because from a scientific standpoint, it is complete bullshit.
No way. I completely disagree with you. That's like saying that a bullet doesn't hurt you that much, but the shock it drives in the air ahead of it does all the damage. Think about the impedance mismatch between the shocked air and the solid ground... it makes no sense.
While you are correct that there is less of a shock in a thinner atmosphere, you have your dama
Re: (Score:2)
You need to consider the relative energy contained in the shock wave versus the kinetic energy of the moving solid object. The solid object driving the shock wins every time... and by a massive margin. That's why it is driving the shock wave in the atmosphere.
Clearly you have not yet seen the elusive Martian Stork Feather Meteorite.
I accept your apology, sir.

I know nothing either, but maybe a big meteorite landed some distance away and made a crater and exploded flinging decent sized fragments out in all directions, this then bounced and rolled to a stop without ending up sitting in a crater.

There probably is one, somewhere. This may be a smaller piece of a much larger impact - I'd expect bits of the meteorite to bounce and land some distance from the main impact site.

Because it stood out from the other rocks in the area. It's easy to imagine that they had Slashdot nitpickers in mind when they wrote that. "How could they tell it wasn't just a rock that's been sitting there for ages and ages?"

Look, Earthlings don't have a monopoly on flubbing rover landings or making unit conversion screw-ups. Fortunately we still have a monopoly on working Mars rovers! They though that since Mar's atmosphere is so weak they could completely ignore air friction and make the thing out of really light and cheap materials, and that melted hunk of slab is all that's left of their rover.
On the other hand, the Euporans are way ahead of us on exploring Neptune.
