Moon dust, scaled in plastic bottles, has arrived at Harvard from NASA's Lunar Receiving Laboratory in Houston...
Four researchers here have started or will soon begin detailed analysis of the lunar soil collected on last July's Apollo 11 mission. Their research will provide a much clearer picture of lunar surface geology and a possible answer to the question of life on the moon...
...From a distance, the lunar soil samples look like light coal dust, but "half or more of the loose stuff is broken-up shards of glass," Frondel said yesterday. Individual pieces are actually white, green, brown or colorless. Besides these fagged particles, the researchers have found smooth beads of glass, shaped like dumbells, baseballs, and gelatin capsules, roughly a millimeter longer...
This glass was probably formed from meteor impacts that splattered molten rock across huge distances, Frondel said. These impacts may also send shock waves comparable to those from an atom bomb blast through the lunar soil, melting some particles into a glass...
...weeks after the Mariner pictures were transmitted, scientists at Pasadena's Jet Propulsion Laboratory were also getting a far clearer look at the red planet itself. In the first fast playback of the 200 TV images radioed by the two probes, they saw a very rough and lunar-like surface. But after considerable electronic enhancement of the pictures, a slow process that increases contrasts and eliminates random "noise" in the radio signals, the scientists have now produced a portfolio of photographs that show three distinctly different types of Martian topography. Besides cratered regions, there are huge, flat, featureless areas...
