Outer Space Adventure - Part 5 - Solving Sudden Meteor showers and Space Debris Problem

So yeah, today, we are going to look into space rocks and debris problemo~
Lets just make a new term "Space Obstacles" for space rocks and debris since we are going to treat them the same out there. Evade or destroy.

Outside there, yeah there is countless twinkle twinkle bling bling stars out there but there is much more of these Space Obstacles floating out there and yep, if we are going to crash onto these things, no matter how many times we shout "Houston Houston~ bla bla bla" it's game over for us and we are going to be part of those Space Obstacles :D

Alright. Look at the picture above. This is the only picture I can get closest to describe this Space Obstacles. Look at the those rocks with the planet directly behind it, what we can see? Pitch Black.
So, what if the background is nothing? We see nothing, yeah, nothing, total darkness, like walking around blindfolded. That is outer space traveling. So how do we solve these problem?

Lets consider:
Idea #1: Attaching spotlights all around the spaceship, making the spaceship looks like a moving concert vessel and try to use camera to detect these Space Obstacles and Pew Pew them off with something.
Problem:
- Those spotlights bulb/LED/etc etc will expire, and need to be exchanged when it expires.
- Extensive Vision Inspection Algorithm will needed to be created to perform this live checking
- When we facing some extreme photon(light) source, lets say some other Sun out there at near range, the Space obstacle will be invisible due to photon(light) bending when passing through the space obstacle.
- The spaceship looks super lame

Idea #2: Using some EM(Photon) wave generator & receiver of some specific frequency (lower than visible light) and generate some pattern, when same pattern is being reflected, we can pinpoint the position of any nearby Space Obstacles and destroy them. Good idea
Problem:
- Will expire also at some point but can be replaced.
Risk:
- Possibility of extensive space EM(Photon) wave interference causing extensive noises.

Idea #3: Using Idea #2, we deploy more of these EM(Photon) wave generator & receiver of different frequencies to reduce the noise using results from all of them combined together to pinpoint location of these Space Obstacles.

I propose Idea #3 to solve this problem.
