How Did the Milky Way Get Its Spiral?

The video discusses the presence and impact of microbes on the International Space Station (ISS). Since 2000, astronauts have brought microbes, including bacteria and fungi, into space. These microbes can pose threats to both astronauts and equipment. Studies have shown that astronauts are the primary source of these microbes. Some species have adapted to survive on surfaces that would typically kill them. The video also highlights the challenges of maintaining cleanliness in space and the potential risks of microbial infections due to a weakened immune system in space. Cleaning methods similar to those on Earth are used, and new technologies are being explored to reduce microbial habitation on the ISS.

What is the primary source of microbes on the International Space Station?

• Equipment and supplies

• Astronauts

• Space debris

• Air filters

Why are scientists concerned about microbes on the ISS?

• They can make astronauts sick

• They can interfere with communication systems

• They might evolve into new species

• They can cause mechanical blockages

How do microbes potentially affect the health of astronauts?

• By causing infections due to decreased immune response

• By improving mental health

• By enhancing their immune system

• By providing essential nutrients

What cleaning method is used on the ISS to prevent microbial growth?

• Using ultraviolet light

• Using sound waves

• Applying disinfectant wipes

• Boiling water

What materials are being tested to reduce microbial habitation on the ISS?

• Wood and plastic

• Paper and cloth

• Glass and rubber

• Silver and copper alloys
