According to their study, this crater
is about 75 miles wide.
Speaking about it, William Bottke, an asteroid expert at the Southwest Research Institute in Boulder, Colorado and a co-author of the paper said, "The only obstacle to doing this has been finding an accurate way to date large craters
on the Moon."
I have walked around and down into the crater
on several occasions--it lies only 40 kilometers (25 miles) north of Pretoria, where I live.
The METCRAX II field investigation of downslope windstorm-type flows in Arizona's Meteor Crater
is described along with first results from the analyses of the extensive dataset.
The researchers admit that there could be colossal craters
that we haven't discovered, Sumner says.
Summary: TEHRAN (FNA)- Lunar Reconnaissance Orbiter (LRO) spacecraft returned data that indicate ice may make up as much as 22 percent of the surface material in a crater
located on the moon's south pole.
Contaminants that exist in or on top of the paint cause craters
by a different mechanism.
Previous estimates suggested that the 800-metre wide, 200 metre-deep Ubehebe Crater
(above) was around 6,000 years old.

Current exploitation plans call for the use of directional drilling to tap into the near-surface reservoirs beneath the craters
. The ministry's technicians are also investigating the water-gas contact within the sub-strata of each crater
, and are looking into the possibility of re-entering suspended wells near Darvaza.
As the straight segment occurs between two craters
, we might examine rim morphology where craters
The first thing most people think of when it comes to the Moon is craters
. These circular depressions range in size from microscopic pits to impressive structures spanning hundreds of miles.
When large asteroids hit the ground, they produce high temperatures and pressures, carving out bowl-shaped features called craters
Pass out small pieces of black construction paper and refer to Step 4 to guide the students in practicing drawing and shading craters
. Explain the different parts of a picture: foreground, and background.
The mission was to repair three road craters
on a corps main supply route.
