These essays are aimed at summarizing the basics of cosmologic investigations and the issues still lingering in our understanding. We also discuss how to address them through high technological developments both laboratory experiments and theoretical approaches.

We will also list & discuss some useful fallout of these developments for applications in understanding & improving planetary (Earth) environment.

These are planned as chapters which are layered approximately like :

Chapter #01: Modern investigations to understand universe

Chapter # 02: Origin of Universe and evolution of universe

Chapter # 03: Deep space technologies to understand galactic and interstellar spaces

Chapter #06: Space based High Technologies for understanding and support earth’s ecosystem
