2. Introduction Modeling and simulation (M&S) has become an essential tool in the design and verification of space systems. Applied judiciously from conception to operation of a system lifecycle, it can provide better, cheaper, and safer solutions for stakeholders.

3. Although some kind of M&S has been used for developing spacecraft since the dawn of the space age, its use has been expressively increasing in recent years. This can be correlated to the advent of faster computers, user-friendly software modeling tools, and an increasing confidence that simulation can replace hardware in many activities related to the verification and validation process of spacecraft.

4. Modelling and Analysis for Mission Success When planning for the complexities of space missions, state-of-the-art mission modelling is paramount to proper preparation.  Satellites form a critical part of our global telecommunication infrastructure, robots carry out simple tasks on the international space station, and spacecraft manning. The complexity and technical nature of these space missions is astounding - relying on the very best tools, technology, and minds to succeed. As the space mission capabilities advance, so do their complexities. Testing and validating mission concepts and systems using the technology of yesterday is becoming increasingly more difficult.  Space Mission modelling using simulation  is developing rapidly alongside the complex challenges of today and tomorrow’s space missions. This technology has vast applications when it comes to space mission rehearsal, training, and sensor modelling

5. Satellite Modelling Satellites are essential tools for meteorology, defence , navigation, communication, and space exploration. Their ability to operate effectively and safely is absolutely paramount to operations around the world. The installation and maintenance of these satellites have to be handled with extreme care, caution, and thorough planning. Satellite modelling is a critical component of  mission preparation . Their main aim is to evaluate performance at a system level. They also help with budget control as the price can easily build up in space missions. Mission support teams rely on modelling tools to provide realistic environmental boundaries as a basis for these tweaks and changes. Sensor geometry, satellite orbit, and altitude variations also need to be carefully considered, along with Earth’s rotation, and relief. Satellite modelling must be able to compensate for distortions and complex interactions between all these areas and many other conflicting factors.

7. Modelling Toolkits Scientists and engineers have a number of modelling tools at their disposal, all forming a vital toolkit for successful space operations:   ● Orbit determination tools give detailed orbit analysis support for the lifecycle of a satellite and its tracking system.   ● Conjunction analysis tools determine how the launch of an object into space is affected by other orbiting objects.  

8. ● Space environment and effects tools to evaluate the effects of the space environment on a spacecraft. These effects include the high levels of debris that are now in orbit. Failure to consider their trajectories could lead to severe mission complications. Equipped with detailed data and analysis from satellite modelling, space mission teams can rest assured every factor and scenario has been through rigorous testing before launch.

9. Role of Simulation Software and Satellite Modelling Simulation software gives engineers and various other mission support members further tools for satellite modelling. They can help in power and fuel budgeting, satellite orbit and constellation analysis, and manoeuvre planning, along with analysing and visualising complex systems with dynamic datasets in 4D.

10. Space Station based Education Game The ISS 3-D Teaching Tool is a tool in which students work their way through several mission scenarios, related to the European curricula. This product is a multilingual, pedagogical tool for teaching space-related topics to pupils aged 12-18

11. Spaceflight Challenge Spaceflight Challenge is an interactive game in which students work their way through several mission scenarios around the International Space Station, completing tasks related to the European curricula. It provides teachers with a multilingual, pedagogical tool for teaching space-related topics to pupils aged 12-18. The product is translated into the 12 ESA Member State languages and comes complete with a Teacher's Guide and a User's Guide.  

12. Future of simulation and modelling in space exploration Simulation technology and ambitious mission objectives continue to propel innovation in space science, exploration and discovery. As simulation capabilities have improved so has the scope of outer space missions. These technologies are showing no signs of slowing down. As they continue to be refined and developed, space missions can be even more ambitious and safe for those operating them. Together with better modelling, analysis and simulation tools, operations, and support can explore outer space in ways once unimaginable. Effective modelling has given engineers, scientists, astronauts, and other team members the opportunity to refine the systems required for ambitious missions, along with developing the skills needed to operate and maintain them. 

13. By maximising familiarity and minimising the chances of unknown factors interfering with a mission, chances of safety and success are vastly improved. The cost-effectiveness of a thorough system and mission preparation can help manage budgets and channel vital resources. Simulation and modelling provide the sector with vast tools to understand and refine the complex systems needed for mission success..
