The Year-Long Twin Astronauts Experiment

The video discusses the challenges of space travel, focusing on the effects of weightlessness, radiation, and isolation on the human body. It highlights NASA's research mission with astronaut Scott Kelly, who will spend a year in space, allowing scientists to study the effects of space on the human body using his identical twin brother, Mark, as a control. Key research areas include the immune system, fluid dynamics, genomic changes, and bacterial studies. The goal is to understand these changes to make future long-term space missions safer.

What is one of the unusual effects of burping in space?

• It leads to a loss of appetite.

• It comes with a liquid component.

• It causes hiccups.

• It makes you feel dizzy.

Why is Scott Kelly's mission to the International Space Station significant?

• He will be the first person to walk on Mars.

• He will be the first to study the effects of space on plants.

• He will be the first to travel to the moon and back.

• He will be in space for an entire year, a record-breaking mission.

How will researchers study the immune system changes in space?

• By monitoring sleep patterns.

• By giving flu shots before, during, and after the mission.

• By analyzing dietary changes.

• By measuring bone density.

What is the purpose of analyzing the twins' genomes during the mission?

• To determine the best diet for astronauts.

• To study the impact of space on memory.

• To find out how space affects hair growth.

• To understand the epigenetic effects of spaceflight.

What is one of the goals of studying bacteria in the twins' digestive systems?

• To improve astronauts' sleep quality.

• To create a new type of space food.

• To understand how space travel affects them.

• To develop new antibiotics.
