| Small impactors deliver meteorites, while large ones infrequently wreak global devastation. |
| Similar to the effects of a thick atmosphere, a vertical column of water would also inhibit the formation of impact craters from smaller impactors. |
| The close dates of the major impact basins suggested that the Moon experienced a late, heavy bombardment of large impactors around 3.8 to 4 billion years ago. |
| Python is a small scale and highly portable system using Vertical Shaft Impactors and pressure jigs to extract the material. |
| Applications include components for implantable devices, bone screws, bone saws, osteotomes, impactors, patella reamers and other orthopedic and spinal instrumentation. |
| Most impactors were around 10 centimeters in diameter and traveled at speeds of up to 72 kilometers per second, Bouley says. |
