Is Your Brain Ready for Mars?

The video discusses the challenges astronauts face during interplanetary travel, including microgravity, radiation, and sleep issues. Microgravity affects fluid distribution, leading to conditions like Spaceflight Associated Neuroocular Syndrome (SANS), which impacts vision and brain function. Radiation in deep space poses significant health risks, necessitating effective shielding solutions. Sleep disturbances arise from the lack of natural light cycles, affecting circadian rhythms. Addressing these issues is crucial for the success of future Mars missions.

What happens to astronauts' appearance when they first reach space due to fluid distribution changes?

• They appear taller.

• They seem puffier in the face.

• Their skin becomes darker.

• Their hair grows faster.

What is the condition called that affects astronauts' vision and brain due to microgravity?

• Spaceflight Associated Neuroocular Syndrome

• Interplanetary Vision Syndrome

• Microgravity Vision Disorder

• Spaceflight Induced Vision Syndrome

How does deep space radiation affect the brain?

• It leads to the formation of plaques similar to those seen in dementia.

• It improves brain connectivity.

• It causes neurons to work more efficiently.

• It enhances memory and learning.

What materials are being explored for shielding against deep space radiation?

• Iron and nickel

• Aluminum and titanium

• Hydrogen and boron

• Lead and copper

What is a major cause of sleep disturbances for astronauts traveling to Mars?

• Lack of exercise

• Inadequate food supply

• Absence of natural light cycles

• Excessive noise in the spacecraft

What type of lighting system has been installed on the ISS to help astronauts with their sleep cycles?

• Halogen lights

• LED lights simulating different times of day

• Incandescent lights

• Fluorescent lights

What is the average amount of sleep astronauts get despite having 8.5 hours set aside for it?

• 5 hours

• 7 hours

• 6 hours

• 4 hours
