Great celestial bodies populate the solar system. For an untrained eye staring at the heavens, the starlight spectacles and endless seas of blackness are nothing short of a miracle. Researchers, however, have developed mathematical equations that may help us understand such mysteries of the universe. From Isaac Newton’s Law of Universal Gravitation to Albert Einstein’s General Theory of Relativity, the scientific community has paved the way for a greater understanding of the great beyond.
Craig Kluever’s dream was born as he found himself awestruck in front of a grainy black-and-white television screen watching Apollo 11 land on the moon. He was in kindergarten. As he puts it, “that just made a big impact on me. Of course, the first thing I wanted to be was an astronaut.” Those early dreams of becoming an astronaut turned instead into a pursuit of the science behind the rockets. Today, the MU Professor of Mechanical and Aerospace Engineering works behind the scenes to solve the kind of problems involved in designing space travel—such as how to take off, how to reach a target, and, more importantly, how to return safely to Earth.
Chicone discusses his recent work on the velocity of particles moving near a black hole. Based on his research, particles moving faster than 70% of the speed of light that travel along the black hole’s axis decelerate, but objects moving perpendicular to that axis accelerate. These findings defy Newton’s Laws and obey Einstein’s Laws of General Relativity.
Craig Kluever’s childhood dream of becoming an astronaut turned instead into the pursuit of the science behind the rockets. Today, the Professor of Mechanical and Aerospace Engineering seeks to solve the kind of problems involved in space missions—like how to take off, and most importantly, how to return safely to Earth. Kluever came to this area of research in graduate school when he had a fellowship with NASA, developing computer programs to help solve problems involved with mission designs that use electric propulsion (as opposed to chemical propulsion). At the time, Kluever recalls, electric propulsion was a brand new technology, and NASA needed predictive computer models to calculate missions, for example to map a trajectory from Earth to Mars using electric propulsion.
