Life in space
Astronauts in space maintain a strict routine to take care of their hygiene and health. They use a dry shampoo, similar to what is used in hospitals, as they cannot shower. They carry personal hygiene kits that include their preferred products. The toothpaste is edible to avoid the need to spit, and wet wipes are used to keep the mouth clean.
For the bathroom, they use toilets that function like vacuums, connected to waste tanks. Each astronaut has a personal urinal in the form of a funnel connected to a hose.
Regarding food, astronauts consume three meals a day designed by nutritionists to ensure the proper intake of vitamins and minerals according to their individual needs. They have options of radiation-sterilized meat, fruits, nuts, sweets, coffee, tea, juices, and lemonade.
Due to the lack of gravity, astronauts can sleep lying down or standing up, but it is essential to secure themselves to avoid floating freely and bumping into things. Generally, they rest in sleeping bags in individual cabins and follow schedules that allow them to sleep a full eight hours after a day of work.
Maintaining their physical health is crucial in space, so astronauts engage in approximately two hours of daily exercise. Exercise equipment is specifically designed to function in microgravity, making lifting heavy objects easier than on Earth.

An object that orbits around a planet. In our solar system, there are hundreds of natural satellites, known as moons.
In addition to these, since 1957, humans have launched thousands of artificial satellites into space. These serve a variety of functions, such as capturing images of the Sun, Earth, and other planets, exploring space to study black holes, stars, and distant galaxies, and enabling global communications.
They also include weather satellites that monitor the climate and the International Space Station, where astronauts work and conduct experiments in Earth's orbit.
The first artificial satellite, known as Sputnik 1, was launched in 1957. Despite its simplicity, consisting of an aluminum sphere the size of a beach ball equipped with four long antennas and powered by batteries, it had a significant impact. Inside, it housed radio transmitters that emitted a distinctive intermittent beep, detectable worldwide.
Artificial satellites are classified into different types based on their orbits. The choice of orbit depends on the satellite's purpose and the services it offers, as well as considerations of cost, coverage, and feasibility.
The five main types of satellites based on their orbits:
- Low Earth Orbit (LEO): Positioned at relatively close altitudes to Earth, they are used for Earth observation and short-distance communications. - Medium Earth Orbit (MEO): Located at intermediate altitudes, they are common in navigation systems like GPS. - Geostationary Orbit (GEO): Positioned at a fixed altitude above the Earth's equator, ideal for telecommunications services. - Sun-Synchronous Orbit (SSO): Allows for periodic Earth imaging and is used in Earth observation and mapping. - Geostationary Transfer Orbit (GTO): Used as an intermediate stage to move satellites from low Earth orbit to geostationary orbit.
These different orbit types allow satellites to fulfill a variety of missions, from Earth observation to space communications and navigation, contributing to a wide range of practical applications today.

While space exploration used to focus on distant destinations, a new race is emerging in the extraction of minerals from the Moon to drive key technologies in our future, such as smartphones, solar panels, and even the possibility of establishing a lunar colony.
China has announced the discovery of a lunar mineral called Changesite-(Y), becoming the third country to identify an unknown mineral on the Moon, after the United States and Russia. This mineral holds the potential to become a future energy source thanks to its helium-3 content, a promising fuel for nuclear fusion, a scarce resource on Earth but relatively common on the Moon. This positions the Moon as an attractive target for helium-3 extraction in preparation for future energy needs.
Lunar exploitation will require the use of key resources such as water, crucial for growing food and potentially as rocket fuel, in addition to helium-3 and rare earth elements to power high-end technologies.
The manufacturing of necessary robots and equipment could take place on the Moon through 3-D printers, leveraging local helium-3 for their power. Over time, this mining activity could lead to exponential growth, similar to historical advancements on Earth such as agriculture and the steam engine.
Robots, along with a handful of astronauts, could establish the foundations for a lunar mining complex that supports our future in space.
