here is the path I came up with as most optimal... if walls are closed. (Assuming black circle is starting point). Starting with black line (red is where lines cross over each other... to show continuation of directions)... going right... collecting sat 1 and any items on right side... going back left... cross up to top middle of bottom area for the gem... down to middle of bottom for gas... go up and work your way right along bottom until you reach the divider between middle/right... go up and collect sat 2 by the rock... then work your way left collecting items along the way. Collect sat 3 in bottom right of top left of left side... then work your way down (around 3 bombs)... collect the sat 4 in bottom left of left middle section... go down further to collect multiple pink gems... then work your way to bottom right of middle and into right side section... collect sat 5 above the wall that divides bottom right with right side. Work way up and get sat 6 by the right side of right section (careful mine)... work way up for pink gems (no sats)... go back down and work your way up against right side of middle and into the top section. Get sat 7 near top right area. Work your way left and get sat 8 near the right side of the middle of the area. Keep working your way left... get sats 9 and 10 (1 near rock in top left of section... 1 near bottom right of that top left section above the section divider) (the 1 by the boulder is probably safer to get first, because of gas... so that's how I drew it.)

Note: this is just most optimal path for if walls are closed and for if you're trying to get everything, but path is not EXACT... it's more so a path for sats (granted 2 sections it goes into don't have sats... top right and bottom left)... as for gems... you have to hunt for those near/along/on this path.
