We have chosen a shape from nature, that provides space for everything the expedition
could ever need. The centre has two floors – one on the surface, that works as an entrance and
storage for essentials to survive outside, and the lower floor works as a control centre as well as a
space for rest and leisure. From this underground floor lead five chambers. The use of these capsules
and the placement of necessities, like bedchambers, working out area, laboratory or restroom, is
movable and easily interchangeable.
This complex is dug underground for one single reason: when we move underground, many
dangers are thereby vanishing, like the high probability of a meteor hitting the accommodation, the
Moon’s surface shields from deadly rays and the temperature control underground is easier.

After careful evaluations we have decided that our base will be located on one of the poles, due to near constant sunlight and more stable heat conditions between 0 degC and -50degC. One of the most likely candidates is the rim of Peary crater on the north pole. Researches have indicated the presence of lava tubes, which after some additional exploration might prove as future base locations due to their nearly friendly temperatures of around -20 degC and the protection they could provide against meteorites and solar radiations. Also the presence of ice on the pole would prove useful, as it can be separated to hydrogen (fuel) and oxygen (vital for survival). The main part of the base is located underground to ensure the maximum protection of the astronauts from meteorites and the deadly solar radiations.

We have long disputed about what shape and form will our accommodation take. We have
contemplated modules in the shape of a honeycomb or a large system of tunnels, however this shape with
five branches is a natural one and it is easily replicable and functional. But you may have the question
of how we aspire to create this elaborate, yet simple shape underground? On Earth, there are many
machines that dig tunnels. Why couldn’t we modify one of these machines to conditions of the
Moon’s soil? These robots would be operated from Earth and The Daisy would be finished, with the
use of 3D printing and digging, before the astronauts’ arrival. As it is possible to 3D print regolith, the main structural construction will be done with a big 3D printer, fully controlable from Earth.

Water is stored in a water tank, which then via canalisation transfers the water into an underground reservoir. The water is kept drinkable by an UV light which disinfects
the water. The urine of astronauts will also be recycled into drinkable water, the same way as it is on the ISS.

One of the modules contains two greenhouses, to provide sustenance and air filtration. Dried foods are
stored in the storage capsule.

Without electricity none of it could work. We have decided to choose two power-providing
systems. One of them is solar energy, from solar panels on the moon’s surface. The other one would
be a small nuclear plant under the surface of the moon. These two systems complete each other and
are almost fool-proof against power shortages or complete blackouts. We always want to have a source of power, even if the other one fails, or even if the solar panels get crushed by a unfortunate meteorite.

We will purify the the air the same way the ISS uses it’s air filtration. Additionally the greenhouses will help in the air filtration.
If the base will be met with a excessive amount of water, spirulina algae could be placed in a water tank to produce not only breathable air, but also nourishment as spirulina is eatable.

In a dangerous situation, just one exit might seem not enough. And it is not. For this sole reason, the
Daisy has a second, emergency exit. Per contra, the possibility of a problem that would need
evacuation is tiny, considering all the capsules can be easily separated by fire proof doors.
The water reservoir as well as the power generator and battery are stored underground too,
for maximum protection. Safety was the main portion of what we kept in mind.

The astronaut crew made up of 6 brave people will be responsible for The Daisy’s functionality. The solar panels will be fully autonomous and will constanly be channeling power into the batteries. The nuclear plant will transfer it’s power via underground cables, but it will need someone’s supervision. There will be people in the laboratory doing research and communicating with Earth. The module dedicated to leisure will consist of a gym needed for the astronauts to stay in shape and other necessities for human life. The individual modules will be connected via tubes, which will provide transportation via an elevator and a emergency ladder, that could also be used normally to save power as it is easier to move around on the Moon with it’s smaller gravitational force. The geodesic module above the surface will serve as a garage for smaller robots (and foldable ones) and as a storage compartment for exploration necessities, which the crew will use daily.
