Ad Astra Cargo Rocket [Unofficial] by SHB2

Cargo rockets can move items between dimensions, and the fuel and cryo fuel tanks on a rocket can be filled from a launchpad through pipes connected to its bottom face. Fluid pipes on the top side of the launchpad carry cargo liquids. Hoppers placed next to a launchpad can insert into and extract from the rocket's inventory directly. The rocket's own tanks and inventory are accessible through the launchpad's faces while the rocket is grounded on the pad.

The author notes that pipes and hoppers now stay in real-time sync with the rocket, and that fluid cargo no longer disappears on landing. Collision detection for descending rockets and the launchpad energy bar in its inventory screen were also fixed. It works with the Forge-compatible Unofficial ChiyahaRe build and is used together with CC:Tweaked for interplanetary item automation.

The 1.3 build is published for Forge only, for 1.20.1 alone. Client and server both need it, so a multiplayer server and every player must run the same build.
