Shape

by The Lander / Design Pane / 1

The overall design of The Lander©® was inspired by the VW microbus of the 60's, using a rectangular shape as an optimal use of available space for a vehicle. The exterior shell is made of boron-carbide, titanium, polyamide-imide, with or without refractory carbon plating.

Structure

by The Lander / Design Pane / 2

The overall structure is 12M in length and 5.5M in diameter; and is made of 5 layers or decks. The structure is made mostly of titanium alloy, welded as monobody frames. The empty weight (OEW) goal is 6 metric tons, or less, and a total weight of 30+MT.

Cockpit

by The Lander / Design Pane / 3

The 5+M cockpit has enough space for 8 to 15 astronauts, plus commander and pilot. There are also 2 lavatories, and 2 or 4 storage spaces. Docking is in the top center of the cockpit. Control panels are covered with plastics, and OLED screens play the role of cockpit window.

Cargo Bay

by The Lander / Design Pane / 3

The cargo bay is 6M in length, and can accomodate several metric tons of cargo. It is large enough for a moon buggy 3.5M in length and 2.5M in width. It also has 2.5 meter cube of upper cabinet storage space. The cargo bay door is deployable up to 10 meters.

Propulsion

by The Lander / Design Pane / 4

Propulsion is provided by eight toroidal aerospikes. They each fit within a one meter square box, underneath the Lander. Thrust is 25±KN per spike. The main engine pumps are located on top of the aerospike assemblies.

Foam & Coatings

by The Lander / Design Pane / 5

The entire structure is coated with a layer of silica areogel. Battery casings and carbon-fiber electrical conduits are filled with foam areogel to prevent electrical fires. Aerogel panels are used where the available space allows it, for both sound and thermal proofing.

Propellant

by The Lander / Design Pane / 7

The propellant is Aerozine50/LOX or Ethanol/LOX. The tanks can hold around 5+MT of aerozine50 or Ethanol, and 11+M of liquid oxygen. The propellant tanks arrangement may differ, depending on the version of the Lander, e.g. pontoon, wheeled, or legged. The propellant section's overall blast-deflecting design adds a margin of safety.

Power

by The Lander / Design Pane / 8

Power is provided by a pair of solar concentrators on top of the Lander. A set of Hydrogen fuel-cell packs are used for backup power in case of emergency. The solar concentrators can provide up to 10+KW/h each.

Lower Deck

by The Lander / Design Pane / 4

All the storage space required for tanks, propulsion, and landing gear is located in the lower and upper decks. The landing legs are powered by hydraulics, and have cupolas or seabirds palmed-feet made of titanium sheets, at the endings. The mobile versions have either wheels or spider-like legs.

Mid Deck

by The Lander / Design Pane / 5

All the storage space required for cockpit and cargo bay is located in the mid deck. The sub-layer of the mid-deck is where all the main fuel pumps are located, alongside Nitrogen, Hydrazine, Halon and Helium tanks, cryocoolers, and heaters.

Upper deck

by The Lander / Design Pane / 7

Water tanks, scrubbers, electrical power generators, etc. are housed in the upper deck. A microwave and LASER dish are used for COMM links back to Earth. A live feed of the entire trip could be relayed back to Earth using a one Gigabit+ bandwidth.

Re-Entry

by The Lander / Design Pane / 7

Re-entry on Earth is done with spoilers deployed and with the help of deceleration parachutes. A circular gliding trajectory is followed until subsonic speed is reached, to be able to right the Lander for vertical landing with thrusters or/and parachutes.
