Sentences with phrase «craters near the moon»

Not exact matches

Since the 1960's scientists thought that only in permanently shadowed areas in craters near the lunar poles was it cold enough to accumulate this volatile material, but recent observations by a number of spacecraft, including LRO, suggest that hydrogen on the moon is more widespread.

In craters near the south pole of the moon, NASA's Lunar Reconnaissance Orbiter found some bright areas and some very cold areas.

Water on the moon, if it exists at all, is probably confined to frozen deposits in a few shadowed craters near its poles.

Brilliant streaks on the crater walls suggest that even the feeble gravity of this moon is strong enough to erode loose material; bluish regions near the crater rim may be younger exposed surfaces.

LRO's early results have already caused a stir: The Diviner Lunar Radiometer Experiment sent back the first global temperature maps of the moon, revealing ultracold pockets in permanently shadowed portions of craters near the south pole.

And a mission to return a sample from the moon's largest impact crater would have been some comfort to lunar scientists still smarting from Obama's decision to redirect NASA's crewed space exploration from the moon to near - Earth asteroids.

The seismographs left on the moon's surface by the Apollo astronauts and the gravity measurements of the 1998 Lunar Prospector probe have provided enough data to explain why there are many more craters on the moon's far side than on the near side.

The impact that formed a large basin known as Orientale in the western area of the moon's near side, which the group investigated in detail, obliterated all prior craters within the basin itself, an area of nearly 700,000 square kilometers.

Dr. Chapman has been the Principal Investigator of many NASA and NSF grants and has been P.I. of research concerning the Late Heavy Bombardment of the Moon (and inner solar system), astronomical observations of very young asteroid families, analysis of NEAR Shoemaker images of Eros, studies of secondary cratering on Mars, and investigations of the cratering records of the Galilean satellites.

The record of history, as written in the many impact craters on Earth and the moon, demonstrate that it is just a matter of time before astronomers discover a near Earth object (NEO) headed toward a collision with Earth.
