GTFO Get To Freaking Orbit (standard version)

The GTFO is a minimal but capable large grid miner, designed to achieve a foothold in orbit as quickly as possible.

Filling the two small hydrogen tanks requires ~36,000 kg of ice. Using throttle controls, you can escape an Earth-like planet using only ~20% of your fuel (assuming no cargo).

The spaceframe was designed so that it can be built immediately as a ground base (see core pic,because you can't build a projector until you have large tubes), then detached and launched immediately as a rudimentary mobile base of operation while establishing a larger facility or mothership in space. The GTFO has abundant free ports for customization and upgrading.

Major functional elements:
2x drills
6x small cargo
1x basic refinery
1x basic assembler
1x survival kit
1x connector
1x O2/H2 generator
2x small H2 tanks
2x batteries
2x solar panels
1x ore detector
1x gyrocope
2x parachute hatch

Note 1: Lacking on-board oxygen storage, you must bring along extra personal O2 tanks and/or ice reserves to avoid suffocation.

Note 2: She's a fragile craft with exposed parts, so mine very cautiously at first and consider only building one forward thruster. Bump into things and you'll find yourself stranded.
