Research payoffs from the out-of-this-world Meteor Crater are ongoing.
Researcher David Kring of the Lunar and Planetary Institute .What's the true age of the crater itself?"Actually, the uncertainty is growing," Kring said. Earlier, three independent methods produced the same number, pegging it at 50,000 years old.
Similarly, the bearing of the impactor is still unclear."I can make the case for nearly any direction, although I think most of the evidence is pointing north to south. The angle is probably on the order of 45 degrees, plus or minus a little bit, to produce a nearly circular or symmetrically-shaped crater. And that's what we have," Kring said.Over the years, Kring has trained active and candidate astronauts at Meteor Crater.
Kring said that as stunning as Meteor Crater is in the first place, he advises future moonwalkers to stand on its rim and gape, but then tells everybody to turn around and imagine another crater just to the left, and a third crater just to the right.
