Take Two And Call Me In The Morning

Aspirin has been used for hundreds of years to relieve pain and reduce inflammation. It belongs to a group of chemicals called salicylates and was originally derived from the bark of the willow tree. But how does aspirin work? When you fall down and scrape your knees, how does it know that it needs to go down to your legs? When you bruise an elbow, ...

NASA's First Historic Challenge

NASAsFirstHistoricChallengeIn a time of uncertainty at home and abroad, an American president proposes bold new steps in the exploration of space. He calls for 'longer strides' which 'may hold the key to our future here on Earth.' He touts the potential of 'even more exciting and ambitious exploration of space, perhaps beyond the moon, perhaps to the very end of the solar system itself.' The year is 1961. The president is John F. Kennedy. But the words ring true today, as NASA aims for new frontiers with a new Vision for Space Exploration. Kennedy's 'Special Message to Congress on Urgent National Needs' came on May 25, just three weeks after Mercury astronaut Alan B. Shepard became the first American in space. Delivered at the height of the Cold War with the Soviet Union, the speech is best known for Kennedy's audacious challenge to NASA and America. 'I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the moon and returning him safely to Earth.'

NASA fulfilled that goal on July 20, 1969, when Apollo 11's lunar module Eagle touched down in the Sea of Tranquility, with Neil Armstrong and Buzz Aldrin aboard. A dozen men would walk on the moon before the Apollo program ended. The last of those men, Gene Cernan, left the desolate lunar surface with these words: 'We leave as we came and, God willing, as we shall return, with peace and hope for all mankind.' Now, NASA is indeed looking to return to the moon, as well as planning new journeys to Mars and beyond. Much has changed in the 43 years since Kennedy's speech. Our Cold War Soviet rivals are now our Russian partners on the International Space Station. And the technological feats Kennedy helped initiate have spawned countless tangible benefits on Earth. Medical technologies, weather forecasting, computer technology and telecommunications can all trace their origins to the space program.

What hasn't changed is the spirit of exploration and discovery. Announcing NASA's new initiative in January 2004, President Bush put it this way: 'Mankind is drawn to the heavens for the same reason we were once drawn into unknown lands and across the open sea. We choose to explore space because doing so improves our lives, and lifts our national spirit.' Chris Cassidy, a member of NASA's 2004 astronaut class, puts the need to explore in more personal terms. 'I hope to be the next guy on the moon.'
