It contains oxygen for breathing, a cooling system to regulate body temperature, and equipment for communication. Additionally, it houses a waste management system and other necessary tools for extravehicular activities (EVAs), ensuring that astronauts can safely operate in the harsh environment of space.

The U.S. space project that provided astronauts with practice piloting was the Space Shuttle program. Astronauts underwent extensive training in simulators that replicated the shuttle’s cockpit and systems, allowing them to practice various scenarios, including launches, landings, and emergency procedures. This hands-on experience was crucial for preparing them for real missions in space. The program ran from 1981 to 2011, successfully completing 135 missions.

Inside a rocket, astronauts perform a variety of tasks essential for the mission, including conducting pre-launch checks, monitoring systems, and communicating with mission control. During launch, they secure themselves in their seats and manage any necessary adjustments to ensure safety. Once in space, they engage in scientific experiments, maintenance tasks, and physical training, all while adhering to strict schedules to maximize their productivity and ensure mission success.

Astronauts in spacecraft are primarily protected from radiation by the vehicle's structure and materials, which can help attenuate some forms of radiation, especially high-energy particles. Additionally, spacecraft are designed with shielding materials, such as aluminum and polyethylene, which are effective at reducing exposure to cosmic rays and solar particle events. When traveling beyond low Earth orbit, mission planners also time spacewalks and activities to minimize radiation exposure during solar events. Finally, spacecraft may incorporate active radiation monitoring systems to provide real-time data on radiation levels.

Astronauts wear specialized space suits known as Extravehicular Mobility Units (EMUs) to protect themselves from the harsh conditions of space. These suits provide life support, temperature regulation, and radiation protection while ensuring mobility during extravehicular activities (spacewalks). The suits are equipped with multiple layers of materials that shield against micrometeoroids and extreme temperatures. Additionally, they feature a helmet with a visor to protect the eyes from solar radiation and a communication system to maintain contact with mission control.

Before lift-off, astronauts undergo extensive training that includes simulations of launch, in-flight scenarios, and emergency procedures. They also participate in physical fitness programs to ensure their bodies can withstand the stresses of space travel. Additionally, astronauts familiarize themselves with the spacecraft systems and equipment they will be operating. Finally, pre-launch medical evaluations ensure they are physically and mentally fit for the mission.

Astronauts bring compressed oxygen to breathe in space, as it allows them to have a reliable supply of breathable air in the vacuum of space where there is no atmosphere. This choice is effective because oxygen can be stored in high-pressure tanks, ensuring that astronauts have enough to sustain them during missions. Additionally, systems like the Environmental Control and Life Support System (ECLSS) recycle carbon dioxide back into oxygen, making it a sustainable option for long-duration missions.

Orbiting spacecraft appear weightless because they are in free fall towards Earth while simultaneously moving forward at a high velocity. This state of free fall creates a condition known as microgravity, where both the spacecraft and its occupants are falling together at the same rate, resulting in the sensation of weightlessness. Essentially, they are continuously falling around the Earth rather than straight down, creating the illusion of floating.

The original Mercury Seven astronauts were pivotal in the early years of the United States space program, symbolizing the nation's commitment to space exploration during the Cold War.
