This essay will delve into the multifaceted contributions of Don Pettit, examining his early life and education, his groundbreaking inventions in space, his participation in multiple spaceflights and research expeditions, and his lasting impact on the field of space exploration.
Born and raised in Silverton, Oregon, Pettit’s early life provided a fertile ground for his budding scientific curiosity. His involvement in the Boy Scouts, achieving the rank of Eagle Scout, instilled in him leadership skills and a commitment to exploration. This early inclination towards scientific pursuits led him to pursue a rigorous academic path. He earned a Bachelor of Science in chemical engineering from Oregon State University in 1978, followed by a Ph.D. in chemical engineering from the University of Arizona in 1983. His doctoral studies honed his analytical and problem-solving skills, preparing him for the challenges that awaited him in the field of space exploration. Before joining NASA, Pettit worked as a scientist at the Los Alamos National Laboratory from 1984 to 1996. This experience provided him with invaluable practical experience in scientific research and development, further solidifying his expertise in chemical engineering and related fields. It was this unique combination of academic excellence, practical experience, and an unwavering passion for space exploration that ultimately led to his selection as a NASA astronaut candidate in 1996.
Pettit’s journey to space began in 2002 as a flight engineer on Expedition 6 aboard the International Space Station (ISS). His selection for this mission, even as a last-minute replacement for another astronaut, highlighted the trust and confidence that NASA placed in his abilities. During his time on the ISS, Pettit proved his mettle by conducting two extravehicular activities (EVAs), demonstrating his proficiency in performing complex tasks in the challenging environment of space. He also actively participated in vital scientific experiments, contributing to our understanding of various phenomena in microgravity. One of the most notable aspects of his first mission was the creation of his popular “Saturday Morning Science” series, where he conducted engaging demonstrations of fluid behavior in microgravity. These videos not only entertained audiences but also served as valuable educational tools, illustrating fundamental scientific principles in a visually compelling way. Even the circumstances of his return to Earth were noteworthy, as the Soyuz landing exposed him to extreme G-forces, further highlighting the inherent risks and challenges of space travel.
Beyond his contributions to scientific research, Pettit is also renowned for his technological innovations in space. His most famous invention, the Zero G Cup, is a testament to his ingenuity and his ability to identify and solve practical problems in the unique environment of microgravity. The Zero G Cup eliminated the need for straws by utilizing the surface tension of fluids to carry liquids along a crease, making it easier to drink in zero gravity. This invention not only received widespread media attention but also earned Pettit the distinction of being the first person to receive a patent for an object created in space. This achievement was even featured in National Geographic magazine in 2009, further solidifying Pettit's reputation as an innovator and a problem-solver. In addition to the Zero G Cup, Pettit also designed and constructed a barn door tracker during Expedition 6. This device enabled him to capture high-resolution photographs of Earth’s surface, including stunning images of city lights at night. This invention showcased Pettit’s resourcefulness and his ability to utilize available materials to overcome technical challenges in space.
Pettit’s career is marked by multiple spaceflights, each contributing significantly to our understanding of space and the universe. His second mission, STS-126 in 2008, was a short-duration mission aboard the Space Shuttle Endeavour, where he delivered essential supplies and equipment to the ISS. During this mission, Pettit conducted groundbreaking experiments on the clumping of solid particles in microgravity, advancing our knowledge of planetary formation. This research provided valuable insights into the processes that led to the formation of planets and other celestial bodies. His third mission, Expedition 30/31 (2011-2012), was particularly significant as Pettit played a key role in capturing the first-ever commercial spacecraft, the SpaceX Dragon. This mission marked a historic milestone in the use of commercial spaceflight for resupply missions to the ISS, paving the way for a new era of collaboration between government agencies and private companies in space exploration. Pettit’s famous quip, “Houston, Station, we've got us a dragon by the tail,” perfectly captured the excitement and significance of this momentous event.
Pettit's commitment to public outreach extends beyond his “Saturday Morning Science” series. He actively sought opportunities to engage with the public and inspire the next generation of scientists and engineers. One notable example is his collaboration with Rovio Entertainment to promote educational videos featuring the Angry Birds franchise. In these videos, Pettit demonstrated basic physics principles in space using the popular Angry Birds characters, making complex scientific concepts more accessible and engaging for young audiences. This innovative approach to science education demonstrates Pettit's understanding of the importance of reaching out to the public and inspiring them to pursue careers in science and technology.
Beyond his spaceflights, Pettit also participated in a fascinating expedition to Antarctica as part of the Antarctic Search for Meteorites (ANSMET) program. During his six weeks in Antarctica, he collected meteorite samples, including a lunar meteorite, and conducted scientific experiments in the extreme environment of the South Pole. This experience provided him with a unique perspective on the interconnectedness of Earth and the solar system. He also demonstrated his resourcefulness and adaptability by performing emergency electrical repairs and dental surgery, showcasing his ability to handle unexpected challenges in remote and isolated environments. Even in Antarctica, Pettit continued his “Saturday Morning Science” series, conducting unique experiments on glacial ice and micrometeorites, further demonstrating his commitment to science education and outreach.
