How do people travel in an international space station?

Options

A. By floating in air
B. By walking in air
C. By seating in air
D. None of these

Answer

### Step-by-Step Solution:

1. **Understanding the International Space Station (ISS)**:
- The International Space Station (ISS) is a large spacecraft that orbits Earth. It serves as a home and workplace for astronauts from various countries.

**Hint**: Remember that the ISS is a collaborative project involving multiple countries and serves as a research facility in space.

2. **Gravity in Space**:
- In space, especially at the altitude of the ISS, there is microgravity. This means that the force of gravity is much weaker than on Earth, but it is not completely absent.

**Hint**: Think about how gravity affects objects on Earth compared to how it affects them in space.

3. **Movement Inside the ISS**:
- Due to the microgravity environment, astronauts do not walk as they do on Earth. Instead, they float and can move by pushing off surfaces. They can also use handrails and footholds to stabilize themselves while working.

**Hint**: Visualize how astronauts move around in a zero-gravity environment; they glide rather than walk.

4. **Traveling to and from the ISS**:
- Astronauts travel to the ISS using specially designed spacecraft, such as the SpaceX Crew Dragon or Russian Soyuz. These spacecraft launch from Earth and dock with the ISS to allow astronauts to enter.

**Hint**: Consider the technology and vehicles used for space travel and how they are different from regular airplanes.

5. **Living and Working in the ISS**:
- Once aboard the ISS, astronauts conduct scientific experiments, perform maintenance, and exercise to counteract the effects of microgravity on their bodies. They have to adapt to living in a confined space with limited resources.

**Hint**: Think about the daily routines of astronauts and how they manage their health and work in a unique environment.

### Summary:
People travel in the International Space Station by floating in a microgravity environment, moving using handrails and footholds, and arriving via specialized spacecraft. They adapt to living and working in space through various routines and practices.
