The U.S. space project that provided astronauts with practice in piloting spacecraft and working in space was the Gemini program. Conducted between 1962 and 1966, Gemini included a series of missions that focused on developing techniques for space travel, including rendezvous and docking, long-duration flights, and extravehicular activities (spacewalks). This program was crucial in preparing astronauts for the Apollo missions that ultimately aimed to land humans on the Moon.

Astronauts wear gloves in space primarily to protect their hands from extreme temperatures, micrometeoroids, and harmful radiation. The gloves also provide dexterity and grip for handling tools and equipment while ensuring a secure seal with the suit to maintain life-support functions. Additionally, they help prevent contamination of sensitive instruments and surfaces in the spacecraft or during extravehicular activities.

Astronauts study subtraction as part of their training to enhance their problem-solving and critical thinking skills, which are essential for navigating complex situations in space. Subtraction helps them manage resources, such as fuel and supplies, and perform calculations necessary for mission success. Additionally, understanding mathematical concepts allows astronauts to communicate effectively with ground control and make quick decisions during emergencies. Overall, mastering subtraction contributes to their overall preparedness for the challenges of space missions.

The Apollo 13 mission, launched in April 1970, faced a critical situation when an oxygen tank exploded en route to the Moon. The astronauts—Jim Lovell, Jack Swigert, and Fred Haise—managed to work with mission control to develop a strategy for safely returning to Earth despite limited resources and life support challenges. They successfully splashed down in the Pacific Ocean on April 17, 1970, demonstrating remarkable problem-solving and teamwork under extreme pressure.

After Apollo 11 left Earth's orbit, it took Buzz Aldrin and Neil Armstrong about 76 hours to reach the Moon. They launched on July 16, 1969, and entered lunar orbit on July 19. The lunar module then descended to the Moon's surface on July 20.

American astronauts typically travel to the International Space Station (ISS) aboard spacecraft launched by NASA or commercial partners. Since the retirement of the Space Shuttle in 2011, astronauts have primarily used SpaceX's Crew Dragon and Boeing's CST-100 Starliner, both part of NASA's Commercial Crew Program. These spacecraft are launched atop rockets, such as SpaceX's Falcon 9, and follow a carefully planned trajectory to dock with the ISS. Once docked, astronauts transfer to the station to conduct their missions.

An astronaut needs strong problem-solving skills to navigate unexpected challenges in space. They must possess excellent teamwork and communication abilities, as collaboration is crucial in confined environments. Physical fitness and adaptability are essential to handle the rigors of space travel and varying conditions. Additionally, a solid foundation in science and technology is vital for operating complex equipment and conducting experiments.

Marc Garneau was influenced by several factors in his journey to becoming an astronaut, particularly his fascination with space and science from a young age. His interest was further fueled by the Apollo moon missions, which inspired him to pursue a career in aerospace. Additionally, his educational background in engineering and his experience as a naval officer and test pilot contributed to his qualifications and passion for space exploration.

The blended word of "astronaut" is "astro" (meaning star) and "naut" (derived from the Greek word "nautes," meaning sailor). Together, they create a term that refers to a person trained for travel in space, essentially a "star sailor."
