Since ancient times, humans have looked to the stars with a desire for exploration and discovery. In the 21st century, that view has become a reality thanks to the space shuttles, ships that have revolutionized our way of interacting with the infinite cosmos. In this article, we embark on a sensational, yet objective and truthful journey to discover the world's space shuttles, their advantages and disadvantages, and the price of reaching the stars.

Advantages: Beyond Earth's Atmosphere

The space shuttles are the pinnacle of aerospace engineering, designed to be reusable, which has allowed a significant reduction in the costs of accessing space1. These spacecraft have facilitated crucial missions to understand our universe and conduct cutting-edge scientific research. Their ability to carry heavy loads and crews, as well as serve as microgravity laboratories, has opened a new horizon of possibilities.

Disadvantages: The Price of Ambition

Despite their achievements, the space shuttles are not without disadvantages. The space shuttle program turned out to be much more expensive than anticipated, with each launch costing around $450 million. Additionally, space exploration carries significant risks, from the possibility of asteroid impacts to the introduction of new diseases to our planet.

The Cost of Dreaming about the Stars

The reusability of the space shuttles has been a major advance compared to expendable launch systems, allowing multiple flights and contributing to greater efficiency. However, the development and maintenance of these ships require considerable investment, reflecting the complexity and advanced technology they contain.

The space shuttle Columbia (NASA designation: OV-102) was the first of NASA's space shuttles to accomplish missions outside of Earth. It was launched for the first time on April 12, 1981, and ended its existence when it was destroyed upon re-entry into the atmosphere on February 1, 2003, taking its seven crew members with it. This historic flight marked the beginning of a new era in space exploration, as Columbia was the first fully reusable space shuttle flight. Over the following decades, NASA operated a fleet of space shuttles, including Columbia, Challenger, Discovery, Atlantis, and Endeavor. These spacecraft were used to transport large loads to various orbits, supply and place orbital modules on the International Space Station (ISS), and maintenance missions, such as the Hubble Space Telescope. Although it was initially anticipated that the shuttles could also bring satellites back to Earth for repairs, this function was not carried out until the existence of the ISS, at which time large loads were brought back with the shuttle, something that the Soyuz could not do due to their more limited capacity. The space shuttle program began in the late 1960s and became a top priority for NASA in the 1970s. Despite challenges and tragic accidents, the space shuttles left an indelible mark on the history of exploration. space.

How Space Shuttle Reuse Worked

The space shuttles were a marvel of aerospace engineering, designed to transport cargo and crew to Earth's orbit and return to Earth safely. Their most notable feature was their reusability, which differentiated them from the Apollo missions, where most components were discarded after a single use.

Here's how reusing the shuttles worked:

Launch: The shuttle was launched from Earth on a rocket. This rocket was powered by solid and liquid fuel engines. Once in space, the shuttle separated from the rocket and began its mission.
Orbit: Once in space, the shuttle entered orbit around the Earth. The orbit continued a curved path around our planet. It traveled at a speed of approximately 28,000 kilometers per hour and took about 90 minutes to make a complete revolution around the Earth.
Mission: The shuttle could perform a variety of missions in space:
Placing satellites in orbit: Shuttles were used to place communication, Earth observation and scientific satellites into orbit.
Repair and maintenance: They carried out maintenance missions, such as repairing the Hubble Space Telescope.
Scientific research: The shuttles also served as microgravity laboratories for scientific experiments.
Transportation of astronauts and cargo: They carried crew and supplies to the International Space Station (ISS).
Return to Earth: After completing its mission, the shuttle began its return to Earth. It landed on a runway similar to that of a conventional airplane. Reusability allowed the same shuttle to be used on future missions.

In short, the space shuttles were a combination of advanced technology, precise logistics, and human bravery. Their ability to travel to space and return to Earth has been fundamental to the exploration and study of our universe. Although the space shuttle program came to an end in 2011, its legacy continues to inspire future generations of space explorers.

Conclusion: Navigating between Reality and Fiction

The space shuttles have captured the imagination of the entire world, offering a reusable means of transportation beyond the confines of Earth's atmosphere. They are a testament to our independent spirit and our ability to overcome challenges. As we continue to explore space, these vehicles will continue to be an essential tool in our quest for knowledge and adventure, reminding us that, despite the costs and risks, the sky is no longer the limit.
