The Lander structure is made up of beams and sheets constructed of a "composite" material. Fiberglass composites are constructed of strong fibers or textiles that are strengthened using glue, or "matrix." The fiberglass in the Lander's structural members provides strength where it is needed most - right at the point where two different materials meet- reducing the need for large, heavy components.
The Lander uses an airbag system to protect its crew should the vehicle hit something on the surface of Mars. Should this happen, the bags will inflate with gas to create a protective shell around the occupants. There are two types of airbags used by the Lander: one for the commander and one for the pilot. Each bag takes about 10 minutes to prepare before use, and can be activated from inside the Lander by either the commander or the pilot.
When building your own Lander, it is important to consider how you will protect your crew should an accident occur. An airbag system is optional equipment and not all Lander crews will use them. However, if you do decide to include airbags in your design, it is important to select the correct type for your environment. The Lander team recommends including this safety feature for any mission to Mars.
The lander is a sturdy, lightweight construction made up of a base and three tetrahedron-shaped side "petals" (pyramid-shaped). The matrix can be either resin-based or metal-based. Resin-based materials become more flexible as they warm from the sun but will not break down under lunar conditions. Metal alloys are designed to withstand high temperatures while being light weight.
Fiberglass composites are very strong yet light weight, which is important for sending back scientific data. They also resist damage from extreme temperatures, which is helpful for maintaining instruments during lunar nights when temperatures plummet to -180 degrees F.
The Lander component parts are assembled on Earth before being sent to the Moon. Once there, the components are bonded together with heat, or cold, depending on the type of composite used. This process creates a solid, durable machine that can stand up to the harsh environment of space.
Scientists have said that if humans were to go to Mars, the best choice of propulsion system would be one that uses fuel cells. Fuel cells use an electrochemical reaction to produce electricity from hydrogen (or other fuels) and oxygen. They are efficient and clean, making them good candidates for space travel.
The majority of the building in this region is mud and bricks, and the majority of the residential structures are composed of timber beams with moisture and heat insulation, clay and straw thatched roofing, and clay and brick walls.

It is worth noting here that, with the introduction of iron beams and bricks into the construction industry, as well as a change to a more durable material for roofs and walls, this type of house came to be considered outdated by modern standards.
However, these houses remain popular among villagers because of their low cost and ability to withstand earthquakes and other natural disasters.
In addition to mud and bamboo buildings, there are also stone houses in this region. The majority of these buildings are temples or monasteries.
There are three main types of stone used for building in China: sandstone, limestone, and granite. Sandstone is hard and heavy, which is good for keeping out heat and cold. Limestone is soft and light, so it can be worked with ease, but it will decay over time unless properly maintained.
Cladding is usually constructed of wood, metal, plastic (vinyl), brickwork, or a variety of composite materials. To avoid condensation and enable water vapour to escape, it can be fastened directly to the frame or to an intermediary layer of battens or spacers. The word comes from the French cloison, meaning "wall," because that is what it does—it walls off one floor of a building from another.
It may be necessary to clad a wall when there is no access to the top floor or when the roof is being replaced. Access floors are used where various types of facilities need to be provided for a number of floors above ground level. These include utility rooms, storage areas, and other such facilities. They are generally constructed on a module system, with each module being the size required to provide the desired function. These modules are then placed in line with each other on the floor above, with an opening left between each one to allow passage of people or equipment. Access floors can also be built using full-size panels, but these are generally only used where there is no risk of any debris falling onto the floor below. They are also useful in providing a uniform appearance to part of a floor space, while giving easy access to all the other parts.
House cladding is available in a wide range of materials and styles. The choice of material should be based on how the finished product is going to be used.
