If he want rare things on any planet he must have bigger ship from the next system. It is the only way. In theory he can shoot, but results of that will be catastrophic, because he is same system tech as Mantis so he will get pod many times, lose many cryo. So, first things first.
1. Explore every planet map
2. Go to prelude.myzen.co.uk/PG/ (The only accurate webpage about PG) and on subpage Blueprints see which Mantis and where you must shoot for blue BPs you need.
3. When you obtain all BPs you need with or without help of your buddies or clan, then you farm to buy them or level up to buy them.
4. When you install those BPs in your ship, not colonial ship, but normal ship Vega 2000, with 6 tech slots (tank, storm, shock or engineer) then finish all story missions, also with or without buddies.
5. Go to next system, and do steps 1-3 on that system too, and when you are about to buy things with new ship, then you can but I suggest not, sell old Vega ship.
6. Go back to Aurora with Antares ship with antares best blue weapons and then search for rare bps (Gold Vega).
Thats the way you do in order to become pro player. If you do this steps this way you will be respected in any clan. Also, these steps cannot be changed, but there is also a faster way to get what you need, by finding a person who have big ship and will to help you from some Clan. But then you will not have respect, and you will be marked as noob.
