Lunar Plasma Transporter

We can start building a Lunar Base now. Current spaceships are capable of achieving this goal. I propose we deploy a Lunar Plasma Transporter (LPT) in LEO. It can be assembled in space in 4 sections: 

1. Plasma Thrusters and solar panels (also the controller), 

2. Fuel reserve (can be split into two sections), 

3. Lunar Plasma Ascender / Descender (LPAD)

4. Lunar payload

The LPT will utilize plasma thrusters. The fuel can be any gas (CO₂ can be used to clean our skies) and will be powered by solar panels. Much higher specific impulse than the liquid rockets, no need for an oxidizer. Even oxygen generated from oxidized metals on the lunar soil can be used to power the rocket. 

Once the LPT is fully assembled in LEO, it would increase its speed using its plasma thrusters and the Suns energy. As the speed increases LPT's distance from Earth would increase and at critical point trans-lunar injection would be triggered. Once the LPT reaches the Moon, it would start orbiting the Moon. It would than release the LPAD, which would safely descent the lunar payload on the Moon's surface. The initial payloads should contain setup to extract gas (can be oxygen or another gas) from the Lunar surface.

The LPT after deploying the LPAD would return Earth. Once LPT is close to the Earth, it would use its plasma thrusters to slow it down to LEO orbiting speed. Then the LPT is refueled in orbit and a new Lunar payload is assembled. The gas generation setup on the moon may require many payloads to be deployed. Therefore, LPAD may need to be refueled by the Lunar Plasma Transporter when it ascents from the lunar surface to retrieve the payload. Once the lunar gas generation is active it would refuel the LPAD on the Moon.
