Glossary term: Cohete
Description: Un cohete es un dispositivo que se utiliza habitualmente para lanzar naves espaciales desde la superficie terrestre al espacio exterior. Para ello, un cohete está compuesto por motores de cohete y depósitos de combustible. Los motores de cohete también se utilizan para controlar el movimiento de las naves espaciales en el espacio exterior, modificando la velocidad o realizando correcciones de rumbo. El principio básico de un motor de cohete es producir un chorro de partículas a alta velocidad, normalmente mediante la combustión de combustible para cohetes. Cuando dicho chorro se dirige en una dirección concreta, el motor del cohete se acelera en la dirección opuesta, como consecuencia de una ley fundamental de la física conocida como conservación del momento. Cabe señalar que el chorro de partículas no necesita empujar contra nada para que se produzca este efecto: los cohetes funcionan perfectamente incluso en el casi vacío del espacio exterior.

The Speed of Spacecraft
Caption: This infographic is part of the "Simplifying Astronomy for Arabic Speakers" project, aiming to present scientific concepts in a simple and accessible way. The design focuses on the speed of spacecraft during the various stages of their launch, illustrating how velocity changes as the spacecraft progresses to reach the desired orbit.
Details of the Stages:
Stage One (Launch):
The spacecraft begins its journey by launching from the launch pad with an increasing speed. The velocity in this stage is influenced by Earth's gravity and atmospheric resistance.
After One Minute:
The spacecraft reaches a speed of approximately 1,600 kilometers per hour (km/h), reflecting a rapid acceleration powered by its engines.
After Two and a Half Minutes:
The rocket boosters are jettisoned, allowing the spacecraft to reach a speed of about 4,800 km/h. At this point, the spacecraft becomes lighter, enabling it to accelerate more efficiently.
Final Stage:
By the end of the ascent phase, the spacecraft achieves its final speed of approximately 28,000 km/h, allowing it to enter the desired orbit around Earth.
Through educational designs like this, the project provides enthusiasts with an opportunity to understand the intricate details of space missions in an engaging and simplified manner.
