Since the first human set foot on the Moon, space exploration has come a long way. From satellites orbiting the Earth to machines sent to investigate objects in the Solar System, space probes have been launched to explore the universe. In this article, we will discuss the three types of space probes: interplanetary probes, orbiters and landers. The space race began with the launch of Sputnik in 1957, which caused panic among American politicians and scientists.
This spurred a decades-long effort to develop and execute space programs around the world. The technology and precision needed to put these satellites into orbit are the result of this research. In 1961, Yuri Gagarin became the first human to travel to space, when he orbited the Earth in the Vostok 1 capsule. Since then, hundreds of satellites have been launched to orbit the Earth and hundreds of people have traveled to space in many different types of spaceships.
Interplanetary ProbesInterplanetary probes are unmanned spacecraft sent to explore objects in our Solar System. They are designed to travel long distances and collect data from planets, moons and other celestial bodies. Since 2000, there have been 10 unmanned expeditions to Mars, including placing spacecraft in orbit around Mars and landing machines called explorers to explore the surface.
OrbitersOrbiters are spacecraft that are sent into orbit around a planet or moon.
They are used to observe and study a planet or moon from a distance. For example, NASA's Curiosity rover was sent to Mars to search for signs of life.
LandersLanders are spacecraft that are designed to land on a planet or moon's surface. They are used to collect samples from the surface and study its composition.
The Apollo 11 mission was an example of a lander mission; Neil Armstrong and Buzz Aldrin became the first humans to set foot on the Moon.
Benefits of Space ExplorationSpace exploration has led to many discoveries that have impacted human life; it is responsible for improvements in telecommunications, meteorology, navigation and many other things that today's society takes for granted. Space exploration can also be a unifying force for cultures around the world, as it can be considered the collective heritage of all humanity. In addition, many medical experiments conducted in space conditions have helped doctors to better understand the human body.
Astronauts are subject to microgravity and a relatively sedentary lifestyle, so space missions have led to advances in research into cardiovascular diseases, diabetes and bone disorders.
