Lunar Transporter

The Spaceship will not land on the moon to transfer its cargo. Instead, there will be a Lunar Transporter.  The Lunar Transporter will be a much bigger version of the Lunar Descent module used on Apollo program. It will be able to descent on and ascent from the Moon. The Spaceship after reaching the Moon will circle on an orbit like Apollo’s Service Module. In the first mission the Lunar Transporter carrying the construction robots will be deployed. The second time the Spaceship brings cargo from Earth Lunar Transporter will ascent from the Moon service with no load. The Lunar Transporter will than reach the orbit where Spaceship circles and land on the Spaceship where a hatch will be opened like in a ship and after Lunar Transporter lands it will close. Inside the Spaceship the Lunar Transporter will be refueled and the cargo from Earth will be placed on the Lunar Transporter. The Lunar Transporter will utilize a similar rocket engine used in the Spaceship. The fuel will be LNG and oxidizer will be LOX. After refueling and cargo loading the hatch will open and the Lunar Transporter will be released which will ascent on the Moon. The Spaceship later will return to Earth. The Spaceship will land on the airfield it took off from. It will have to consume fuel during landing to reduce its speed. The surface of the Spaceship should not heat much which improves reliability.
