problem statement: your task is to create a program that allows a user to undertake a journey through the solar system, visiting different planets.
Requirements:
use a while loop to keep the expedition going until the user decides to return to earth.
include details about each planet as the user approaches it.
Add space travel challenges that the user must solve to continue the journey (e.g., fuel management, navigation through asteroid fields).
Sample output:
Welcome to the space expedition tracker!
Your journey through the solar system awaits.
Current location: Earth
Next destination: Mars (Enter 'go' to continue or 'return' to go back to earth): go
Approaching Mars...
Beware of a small asteroid field ahead! Navigating...
Successfully reached Mars! Here's a view of Olympus Mons, the largest volcano in the solar system.
Returning to Earth...
Thank you for exploring the solar system with us!
