Here is how big of a crater was left.

This is European space agency Mars Express, image of a crater on Mars and in the middle of the crater we have liquid water, we have ice.

Mars has the largest impact crater in the solar system, Hellas Basin.

Some of the bluest water in the world is found in Crater Lake.

So, this is called Victoria Crater, which is about a few football fields in size.

So, specifically what we are doing now is that Rover is going down in that crater.

We know it was that big because of the impact it had and the crater it left.

There is a median point between tiny rock and gigantic rock, and in fact, if any of you have ever been to near Winslow, Arizona, there is a crater in the desert there that is so iconic that it is actually called Meteor Crater.

In Meteor Crater it was made of metal, and metal is much tougher, so it made it to the ground.

(d) The seat of the explosion (the resulting crater) was flooded with water in the days following the explosion after the local authorities Police had failed to prevent water from being turned on and released into the crater through the fractured pipes at the scene, thereby damaging or even eliminating vital evidence

The Lebanese security forces have recovered small parts of a Mitsubishi truck from the crater, and from the surrounding area of the explosion.

Lake Manicouagan, a ring shaped lake in Quebec, Canada, is all that remains of a crater from a massive impact over 200 million years ago.

And the most amazing thing that came out of that mission was a strong hydrogen signature at Shackleton crater on the south pole of the moon.

For example, the lidar system compiled a complete map of lunar elevations, discovering a 12 kilometer deep impact crater at the lunar south pole in the process.

This, we later found out, is, in fact, a crater, but there are very few craters on the surface of Titan, meaning it's a very young surface.

The purpose was to make a crater to excavate the material and see what was underneath the surface of this comet, which we learned quite a bit about.

The Mission recovered a piece of metal from the crater resembling metal used in truck parts and bearing evidence that supports the theory of a surface overground explosion.

And the first paper is a standard scientific paper presenting evidence, Iridium Layer at the K T Boundary, Potassium Argon Dated Crater in Yucatan, Indicate That an Asteroid Killed the Dinosaurs.

The analysis of the fragments caused by the explosion and of the shape and form of the crater gives indicators equally supportive of hypotheses of a surface and a subterranean explosion.

This is one very large crater. Geologists love craters, because craters are like digging a big hole in the ground without really working at it, and you can see what's below the surface.

(c) The Mission can say with certainty that parts of a truck were brought to the scene of the explosion by a member of the security forces some time after the assassination and were placed in the crater and subsequently photographed in the crater by members of the security forces, thus creating serious suspicion and doubt about the actual involvement of this truck in the assassination and seriously damaging the credibility of the main line of investigation.

The National Center for Disaster Prevention warned Mexicans on Saturday to stay away from the volcano after activity picked up in the crater and it registered 183 emissions of gas and ash over 24 hours.

(e) Parts of a pickup truck were brought to the scene by members of the security services, some time after the incident, and were placed in the crater and subsequently photographed and labelled as evidence

Now, this is not a 200 mile wide crater, but then again you can see the rock which is sitting right here, about the size of a football, that hit that car and did that damage.

We can do it by jump starting with an industrial Lewis and Clark expedition to Shackleton crater, to mine the moon for resources, and demonstrate they can form the basis for a profitable business on orbit.

So what you are seeing here are the layers on the wall of that crater, and the Rover is going down now, measuring, you know, the properties and analyzing the rocks as it's going down, you know, that canyon.

The American dollar soared, the Japanese yen went into orbit, the euro fell to earth, and the British pound crashed, leaving a giant crater. Emerging market currencies were hammered, as were commodity currencies such as the Canadian, Australian, and New Zealand dollars, and the South African rand.

Sancho, which would retreat to a safe distance before the impact, would then return to a close orbit to determine the changes in the asteroid's orbit and state of rotation, as well as in its shape, and (optionally) to collect samples of the fresh subsurface material exposed by the crater formation.

Its view on the nature and type of the explosion is based on its experts' interpretation of four main elements (a) the dispersion, size and shape of fragments resulting from the explosion (b) the size and shape of the crater created by the explosion (c) ballistics interpretations and (d) interpretations of the damage to the buildings in and around the area of the explosion.

It was huge. To give you a sense of the scale, okay, there you go. The scale here is 50 miles on top, a hundred kilometers on the bottom. This thing was 300 kilometers across 200 miles an enormous crater that excavated out vast amounts of earth that splashed around the globe and set fires all over the planet, threw up enough dust to block out the sun.
