| Astronauts G. David Low (left), Marsha Ivins (center), and Bonnie Dunbar (right) perform medical tests using an echocardiograph onboard the space shuttle Columbia. An echocardiograph uses high-frequency sound waves to take pictures of the heart. One of the main objectives of the space-shuttle program is to determine the effects of weightlessness on the human body. | ||||||
