The Berlin Wall

A view of the East side of the Berlin Wall, taken in 1990 (after the border was opened). The graffiti seen in the photo would date from after the border was opened. Most sections of the Berlin Wall were damaged by both local residents and tourists during the period after the wall was opened,

Berlin Wall From Wikipedia, the free encyclopedia

The Berlin Wall (German: Berliner Mauer, Russian: Берли́нская стена́, Berlinskaya stena), known in the Soviet Union and in East Germany as the "Anti-Fascist Protective Rampart," was a separation barrier between West and East Germany.

An iconic symbol of the Cold War, the wall divided East and West Berlin for 28 years, from the day construction began on August 13, 1961 until it was dismantled in 1989. During this period around 1000 people were killed trying to escape to the West.

When the East German government announced on November 9, 1989, after several weeks of civil unrest, that entering West Berlin would be permitted, crowds of East Germans climbed onto and crossed the wall, joined by West Germans on the other side in a celebratory atmosphere. Over the next few weeks, parts of the wall were chipped away by a euphoric public and by souvenir hunters; industrial equipment was later used to remove the rest of it.

The fall of the Berlin wall paved the way for German reunification, which was formally concluded on October 3, 1990.

The Lunar Roving Vehicle (LRV) was an electric vehicle designed to operate in the low-gravity vacuum of the Moon and to be capable of traversing the lunar surface, allowing the Apollo astronauts to extend the range of their surface extravehicular activities. Three LRVs were driven on the Moon, one on Apollo 15 by astronauts David Scott and Jim Irwin, one on Apollo 16 by John Young and Charles Duke, and one on Apollo 17 by Gene Cernan and Harrison Schmitt.

Each rover was used on three traverses, one per day over the three day course of each mission. On Apollo 15 the LRV was driven a total of 27.8 km in 3 hours, 2 minutes of driving time. The longest single traverse was 12.5 km and the maximum range from the LM was 5.0 km. On Apollo 16 the vehicle traversed 26.7 km in 3 hours 26 minutes of driving. The longest traverse was 11.6 km and the LRV reached a distance of 4.5 km from the LM. On Apollo 17 the rover went 35.9 km in 4 hours 26 minutes total drive time. The longest traverse was 20.1 km and the greatest range from the LM was 7.6 km. The Apollo Lunar Roving Vehicle
