Step 1
First start off with the size of the image that is suitable I recommend sizes of 200 PX x 200 PX

Then fill the color of the background to black

Step 2
Get a suitable space image with stars I used this one (feel free to use it yourself)



Then get a picture of a satellite

I used this one below (also free feel to rip)



Step 3

Shrink this to size and add it to your image

Step 4

Go to Filter > Render > Lens Flare and make sure you have the background layer selected.
You may need to experiment to get a good look.

You may want to add a few lighting effects or maybe duplicate the layer and add a soft light or something

Step 5
Here’s my finished Result Below
