Philip M. Condit is Chairman and Chief Executive Officer of The Boeing Company, the largest aerospace business in the world. In 1997 Financial World named him "Chief Executive Officer of the Year." Always fascinated by airplanes and flight, he first earned his flying license at age 18. he first joined Boeing as an aerodynamics engineer in 1965 and worked his way up through the ranks, playing major roles in the development of the 757 and 777 aircraft. He is only the seventh man to lead Boeing in its 80-year history. As the world's largest manufacturer of both military and commercial aircraft, the company generates more than $48 billion in annual revenues.

Daniel Goldin is the Administrator of NASA, the National Aeronautics and Space Administration. After years of research on electric propulsion systems for human interplanetary travel, he led a team of engineers working on the Strategic Defense Intitiative. In 1992 he was appointed by President Bush to direct America's space program. He led the agency through a period of dramatic revcovery, streamlining its operation to work more swiftly and economically without compromising safety. Under his leadership, NASA has developed two all-new space vehicles and completed the automated Pathfinder mission to Mars. His redesign of the Space Station program succeeded in winning funding for the project from Congress by a 123-vote margin.

Leon Lederman is recognized as the world's foremost experimental physicist, one of the very small group who revolutionized our understanding of the subatomic world. In the late 1950s and early '60s, he participated in the discovery of the K-meson particle and the non-conservation of parity during muon decay. In 1962, with Melvin Schwartz and Jack Steinberger, he designed and performed an experiment that proved the existence of the muon neutrino, an effort that eventually earned the three scientists the Nobel Prize in Physics. He led the efforts which found the first anti-matter particle in 1965 and the bottom quark in 1977. As Director of the Fermi National Accelerator Laboratory in Batavia, Illinois he laid the groundwork for discovery of the mysterious top quark. Since stepping down as director, he has continued to write and teach, and has campaigned vigorously to improve science education in the United States.

Story Musgrave, M.D. is the oldest astronaut in the U.S. space program. He has logged more than 850 hours in space, and has more Space Shuttle missions to his credit than any other astronaut. He was the first to perform a space walk from the Shuttle and gained widespread fame when he performed three spectacular space walks to repair the Hubble Space Telescope. Besides his medical degree from Columbia University, Story Musgrave has bachelor's degrees in mathematics and chemistry, and master's degrees in business, computer programming, biophysics and literature. It should surprise no one to learn that, in his seventh decade, Story Musgrave is studying for yet another graduate degree, and preparing for further missions in space.

Donna Shirley first began work on Mars exploration at the Jet Propulsion Laboratory in 1966. Since then she has commanded a wide range of projects for NASA, including exploration studies, automation and robotics, space station programs, mission design and system engineering. She won international recognition as Manager of NASA's Mars Exploration Program. She led the team that built the Sojourner Rover vehicle which explored Mars as part of the 1997 Pathfinder mission.

CURRENT EVENT EXPLORATION (Web lesson)

John Glenn and the Science of Aging

John Glenn, Mercury astronaut and revered hero of the United States space program, was given another chance to experience space travel. The Space Shuttle Discovery took off with Glenn and six other crew members on October 29, 1998, for an eight-day mission.

In this lesson, you will explore the Web to find out more about John Glenn's mission and its role in contributing to our understanding of the science of aging.

Question for Exploration

How will the results of this mission impact future studies of the aging process?

PROCEDURE

1. Collect background information. In order to formulate an answer to the "Question for Exploration", you'll need to conduct some research to gather pertinent information and data about the topics. Some suggested areas for research are listed below, but you may find that you need to answer additional questions to make an informed response. A list of Web sites is provided, at the end of the procedure section, to help jump-start your search. If you need to gather information from additional resources, be sure to evaluate their validity. Government and university sites generally have more reliable information than personal or commercial sites. Keep a record of the information you've collected, as well as the source of that material. Include both the Web site name and URL address.

  • How does the aging process impact the body?
  • How does space travel impact the body?
  • How does space travel mimic the aging process?
  • What aging experiments were conducted on Glenn's mission?
  • What information will researchers gain from these experiments?
  • Are there additional experiments that need to be conducted in space to research the aging process?
  • Are the results of these experiments applicable to the general population?

2. Synthesize the information that you've collected to develop a response to the "Question for Exploration". The format for that response, (written, oral, Web-based, etc.) will be decided upon by your teacher.
