# The role of the background in past and future X-ray missions

## TL;DR

This paper reviews how background noise has impacted past X-ray missions and discusses strategies to mitigate these issues in future missions to enhance scientific data analysis.

## Contribution

It provides a comprehensive review of past X-ray missions' background challenges and explores future solutions to overcome background limitations.

## Key findings

- Background noise has historically limited data analysis in X-ray astronomy.
- Lessons from past missions can inform future background mitigation strategies.
- Future X-ray missions can significantly improve data quality with better background management.

## Abstract

Background has played an important role in X-ray missions, limiting the exploitation of science data in several and sometimes unexpected ways. In this presentation I review past X-ray missions focusing on some important lessons we can learn from them. I then go on discussing prospects for overcoming background related limitations in future ones.
