SIMOC Presets

The Presets are provided to give users a sense of the various levels of complexity, and the challenges in relatively simple configurations. None of the four presets are perfectly configured, meaning each has room for improvement, some more dire than another.

You can run the Presets from the SIMOC server or more quickly download the Presets and run locally.

One Human

SIMOC Preset 1 Human

Location: Mars
Duration Length: 10 Days
Inhabitants: 1
Food: 100
Crew Quarters: Small
Greenhouse: None
Solar PV Array: 30
Batteries: 1000
ECLSS: 1

This Preset presents the simplest case: a single astronaut in the small crew quarters. The single Environmental Control and Life Support (ECLSS) rack provides adequate atmosphere and water recycling and waste processing. Food rations sustain the astronaut for the duration of 30 days.

  • Take note of the regularity of ECLSS, power consumption, and day/night power cycles.
  • Despite the solar panels, the battery is gradually running low. How can this be remedied?

 

One Human and a whole bunch of Radishes

SIMOC Preset Radish

Location: Mars
Duration: 30 Days
Inhabitants: 1
Food: 100
Crew Quarters: Small
Greenhouse: Small
Solar PV Array: 70
Batteries: 1000
ECLSS: 1

As with the first Preset, we are back to just one human and one ECLSS rack. However, now we have added 40 square meters (4m x 10m) of radish plants and additional solar panels to power the greenhouse lights. Mark Watney had potatoes. We prefer something a bit spicier.

  • Compare the CO2 levels of the 1 Human and Radish simulations. What do you notice?
  • While we are consuming more power, what happens to the battery level from start to finish?
  • What happens to Food at time step 599?

 

Four Humans

SIMOC Preset 4 Humans

Location: Mars
Duration: 10 Days
Inhabitants: 4
Food: 100
Crew Quarters: Small
Greenhouse: None
Solar PV Array: 30
Batteries: 1000
ECLSS: 1

This Preset is similar to One Human but with four astronauts instead of one. However, it appears someone forgot the pre-flight checklist as they yet retain a single ECLSS rack which is designed for a maximum of 3 people. Clearly, this is not a good situation.

  • Which mission critical systems are failing?
  • What would need to be modified for this mission to succeed?

 

Full Garden

SIMOC Preset Full Garden

Location: Mars
Duration: 100 Days
Inhabitants: 4
Food: 1200
Crew Quarters: Medium
Greenhouse: Small
Solar PV Array: 400
Batteries: 2000
ECLSS: 1

This is the most complex of the Presets as it includes 4 astronauts, a much larger solar PV array, twice as much battery storage, and again just one ECLSS rack designed to support a maximum of 3 humans. as with the Four Humans preset. However, this time around we have a garden with a variety of plants that conduct their own carbon dioxide sequestration. But plants need CO2 to produce oxygen. Will they have enough given just four humans as their sole supply?

  • Notice how the CO2 level rises and falls again. Why?
  • Why does the CO2 sequestration go into a chaotic pattern during the mission?

 

Custom Preset

SIMOC Custom Preset

As soon as you make just one adjustment to any of the Presets, the Custom Preset option becomes visible. You can save your custom preset within SIMOC, or download it from the Main menu, to be reloaded for a future run.
