Hiroshima Anniversary: Atomic Bomb Attack Remembered On 67th Anniversary

 Japan marked the 67th anniversary of the world's first atomic bomb attack with a ceremony Monday that was attended by a grandson of Harry Truman, the U.S. president who ordered the bomb dropped on Hiroshima.

About 50,000 people gathered in Hiroshima's peace park near the epicenter of the 1945 blast that destroyed most of the city and killed as many as 140,000 people. A second atomic bombing Aug. 9 that year in Nagasaki killed tens of thousands more and prompted Japan to surrender to the World War II Allies.

The ceremony, attended by representatives of about 70 countries, began with the ringing of a temple bell and a moment of silence. Flowers were placed before Hiroshima's eternal flame, which is the park's centerpiece.

NASA's Mars Science Laboratory mission is the most ambitious, complex mission in the history of robotic space exploration

NASA's Mars Science Laboratory mission is the most ambitious, complex mission in the history of robotic space exploration. On August 5/6, 2012, the mission will set down a large, mobile laboratory - the dune buggy-sized Curiosity rover - using a new form of precision landing technology that makes many of Mars' most intriguing regions viable destinations for the first time.

During the 23 months after landing, Curiosity will analyze dozens of samples drilled from rocks or scooped from the ground as it explores with greater range than any previous Mars rover.

Curiosity will carry the most advanced payload of scientific gear ever used on Mars' surface, a payload more than 10 times as massive as those of earlier Mars rovers.Its assignment: Investigate whether conditions have been favorable for microbial life and for preserving clues in the rocks about possible past life.
