Spacecrafts are huge machines that are used to travel in space. There are different types of spacecraft, each designed in a different way for a different purpose. It is a very risky job to travel in space as don’t have enough information about the climate, pressure, and gravity on other planets about objects in space. So, we don’t know how our body will react in unknown conditions. Hence, scientists cannot always send an astronaut in space.
Sometimes small, robotic spacecraft are sent to explore planets, moons, comets, and asteroids in our Solar System. These machines are sent without astronaute and are called space probes. There are many types of space probes such as, landers and rovers.
So, what do we call a spacecraft that takes astronauts into the space? It is called a space shuttle. A space shuttle lands on a planet. It does not just carry astronauts but also space probes that can be left in the space while the space shuttle comes back to Earth.
