Deutsch: Cluster / Español: Grupo / Português: Aglomerado / Français: Grappe / Italiano: Gruppo /

A cluster refers to a group or arrangement of objects or systems that are connected or related in some way. Clusters may be used in a variety of aerospace applications, depending on the specific needs and requirements of the system or mission.

There are many different types of clusters that may be used in the aerospace industry, each with its own specific characteristics and capabilities. Some common types of clusters include:

1. Rocket clusters: A rocket cluster refers to a group of rocket engines or other propulsion systems that are arranged together and used to power an aerospace vehicle. Rocket clusters may be used to provide additional thrust or lift for a given mission, or to enable the operation of an aerospace vehicle in different environments or conditions.

2. Cluster missions: A cluster mission refers to a space exploration or scientific mission that involves the use of multiple spacecraft or other aerospace systems that are coordinated or connected in some way. Cluster missions may be used to study a particular scientific phenomenon or to explore a specific region of space.

3. Clustered systems: Clustered systems refer to groups of aerospace systems or components that are connected or coordinated in some way in order to achieve a specific objective. Clustered systems may be used to provide additional capabilities or to enable the operation of an aerospace system in different environments or conditions.

Collimation refers to the process of aligning or adjusting optical components, such as lenses, mirrors, or other optical devices, so that light rays or other electromagnetic waves remain parallel as they pass through or reflect off these components. The primary goal of collimation is to ensure that light or radiation remains focused and does not diverge or converge unnecessarily.

In physics, a collision is any event in which two or more bodies exert forces on each other in a relatively short time. Although the most common use of the word collision refers to incidents in which two or more objects collide with great force, the scientific use of the term implies nothing about the magnitude of the force.
