LIFE SUPPORT
Congratulations, you have been chosen as the Life Support (LS) officer for this important mission. Your job is to maintain the critical life support systems onboard the spacecraft. Without this system, the astronauts cannot survive in space.
Your objectives for this mission are:
- Track vital humidity, air pressure, and oxygen systems onboard the Marius, and
- Keep the Mission Commander safe
You will need to follow every step in these TASK CARDS, without skipping a single step. If you find at any point that the readings from the spacecraft are not safe, you must inform the crew! Do not begin the first step until told to do so by the Mission Commander.
If you need assistance at any point during the mission, send am essage to “Help Desk” in the call software CHAT. They are there to answer your questions and provide help for the duration of the mission.
HUMIDITY RESEARCH
Follow these directions for researching RELATIVE HUMIDITY:
- Read the notes from the previous Life Support officer by clicking on the box labeled NOTES.
NOTES
Relative humidity is a measure of how much water is in the air, relative to how much water the air can hold. Relative humidity is written as a percentage. If the relative humidity is too high or too low, then equipment onboard the Spacecraft may not operate properly. The instrument used to measure relative humidity is called a hygrometer.

HUMIDITY DATA
Follow these directions for collecting data on RELATIVE HUMIDITY:
1. Answer the RELATIVE HUMIDITY RESEARCH questions in the HUMIDITY DATA LOG by clicking here.
2. Locate the CHAT in your call software.
3. Select “COM” from the drop-down menu.
4. Type the following message:
This is Life Support. Please use the ________ to send the relative humidity onboard the Spacecraft as soon as possible.
5. Once you have typed it in the CHAT, make sure to hit SEND or hit ENTER so that the COM officer can read it and deliver it to the Mission Commander.
6. Read the information on safe humidity levels by clicking on the box labeled SAFETY.
SAFETY
The humidity in the spacecraft is controlled by the Life Support System, labeled LS 1-3 inside the vehicle. Astronauts use approximately 93% of the water they produce. That includes breath, sweat and urine (pee). This keeps the humidity on the station down. It also helps maintain the station’s water supply.
The relative humidity must stay below 70%. If it gets higher, microorganisms may start to grow in the spacecraft and make the astronauts sick and clog other life support systems. High humidity may also damage electronic equipment.

HUMIDITY DATA ANALYSIS
Follow these directions for analyzing RELATIVE HUMIDITY:
1. Compare the hygrometer reading onboard the Spacecraft to your research to decide if the humidity reading is normal.
2. Click “yes” or “no” to indicate if the relative humidity is normal or not, then click “Submit”. If not normal, click here: EMERGENCY.
3. If you answered “yes”, locate the CHAT in your call software.
4. Select “COM” from the drop-down menu.
5. Type the following message:
This is Life Support. The relative humidity onboard the Spacecraft is normal.
6. Once you have typed it in the CHAT, make sure to hit SEND or hit ENTER so that the COM officer can read it and deliver it to the Mission Commander.
7. Once this is completed, continue to the section labeled “AIR PRESSURE RESEARCH” and follow the task cards.
AIR PRESSURE RESEARCH
- Read the notes from the previous Life Support officer by clicking on the box labeled NOTES.
NOTES
The air pressure at sea level on Earth is 1040 millibars, or 30.7 inches of mercury. Although humans can survive in slightly lower or higher air pressures, the equipment onboard the spacecraft cannot. To maintain a safe environment, air pressure must remain consistent onboard the spacecraft during the mission. A normal change in air pressure is -/+ 17 millibars.
2. Answer the AIR PRESSURE RESEARCH questions in the AIR PRESSURE RESEARCH DATA LOG below. Click “Submit” when you’ve answered the questions.

AIR PRESSURE DATA
Follow these directions for collecting data on AIR PRESSURE:
1. Locate the CHAT in your call software.
2. Select “COM” from the drop-down menu.
3. Type the following message:
This is Life Support. Please send the air pressure onboard the Spacecraft in inches of mercury.
4. Once you have typed it in the CHAT, make sure to hit SEND or hit ENTER so that the COM officer can read it and deliver it to the Mission Commander.
5. Read the information on how to convert inches of mercury to millibars by clicking on the box labeled CONVERT.
CONVERT
Multiply the air pressure value in inches of mercury by 34 to convert the value to millibars.
6. When the Mission Commander sends you the reading for air pressure, open the AIR PRESSURE DATA LOG to record the data.

AIR PRESSURE ANALYSIS
Follow these directions for analyzing AIR PRESSURE:
1. Compare the reading onboard the Spacecraft to your research to decide if the change in the air pressure is within normal range.
2. Click “yes” or “no” to indicate if the air pressure change is normal or not, then click “Submit”. If not normal, click here: EMERGENCY.
3. If you answered “yes”, locate the CHAT in your call software.
4. Select “COM” from the drop-down menu.
5. Type the following message:
This is Life Support. The air pressure onboard the Spacecraft is normal. Please check again in 15 minutes.
6. Once you have typed it in the CHAT, make sure to hit SEND or hit ENTER so that the COM officer can read it and deliver it to the Mission Commander.
7. Once this is completed, continue to the section labeled “OXYGEN SYSTEM RESEARCH” and follow the task cards.
OXYGEN SYSTEM RESEARCH
Follow these directions for researching the OXYGEN levels on the spacecraft:
- Read the notes from the previous Life Support officer by clicking on the box labeled NOTES.
NOTES
In the spacecraft, oxygen is created by running electricity through water. For the oxygen to arrive at the cabin of the spacecraft, it runs through a bypass valve system. Each bypass valve is labeled with a number, such as BV-1 or BV-2. Open valves have a green color light, while closed valves have a red color light. For the valve system to be operational, it must be set in this configuration below:

7. The MICROPHONE button will have two states: on and off. To test that it works, say the entirety of the following message to Mission Commander:
This is Life Support to Spacecraft. Do you read me, over?
8. Wait for a response from the Mission Commander. If there is no response, press or click the MICROPHONE button to ensure you are not muted, and then resend the message. If you get a response from the Mission Commander, that means the communication system is working, and you may continue to the next step.
