So, I think I'm ready for me and my girls to go to Mars. I'm not super familiar with RFTools so what I've done is made 2 each of the dialer, the matter transmitter, and matter receiver. I placed one of each on the moon and named it moon base (named the receiver). I plan to use the super giant star/harvester/container as my initial power source on Mars to operate the oxygen generation machines and the rftools machines once we get there. Is this going to work? Thank you!
Should work, but my suggestion would be to try the complete setup on the moon first. You probably want to add also a Dimensional Anchors (chunk loaders) on both sides. They are really cheap to make in this pack.
Also fairly cheap is a Basic Capacitor Bank, always better to have some energy buffer.
And there is a really simple way to have access to oxygen anywhere and anytime: One of the quests is to make a Dimensional Chest and it gives you a second chest as reward. Place a chest next to the Oxygen Compressor and connect it to the bottom of the compressor using a Refined Relocation tube. Put an Extractor module into both sides of the tube and set them to extract a single item every 2-3 seconds. Craft a few empty canisters and drop them into the chest. It will take an empty oxygen canister out of the chest, place it in the compressor and then put the full canister back into the chest.
Take the other chest to Mars, this will give you an unlimited supply of oxygen there. (At least as long as the collector and compressor on the moon are chunkloaded.) Or, going one step further, take also an oxygen decompressor and bubble generator/sealer to Mars. The decompressor can take the tanks out of the chest, use them and put the empty tanks back. The compressor on the other side will fill them back up.
At T2 replace the Refined Relocation tubes with EnderIO itemducts and both sides set to In/Out. Cheaper and works just as well.
