first humans in space, first space shuttle flights, first humans on the moon

Answer 1

To determine the correct chronological order of the key events regarding space exploration, let's identify the dates of each event:

1. First humans in space: Yuri Gagarin became the first human in space on April 12, 1961.
2. First humans on the Moon: Neil Armstrong and Buzz Aldrin landed on the Moon on July 20, 1969.
3. First space shuttle flight: The Space Shuttle Columbia launched on April 12, 1981.
4. Hubble Space Telescope launch: Launched on April 24, 1990.
5. Last humans on the Moon: The last Apollo mission, Apollo 17, occurred in December 1972.
6. First lander on Mars: Viking 1 landed on Mars on July 20, 1976.
7. First humans on Mars: This has not yet occurred as of my last knowledge update in October 2023.
8. Launching of the International Space Station: The first module, Zarya, was launched on November 20, 1998.

Now let's evaluate the provided responses:

1. first humans on the moon, first lander on Mars, first space shuttle flight

   • Incorrect order.

2. first humans on the Moon, first humans on Mars, launching of the International Space Station

   • Incorrect order (humans have not yet landed on Mars).

3. first space shuttle flight, Hubble Space telescope launch, last humans on the moon

   • Incorrect order (first humans on the Moon came before the first shuttle flight).

4. first humans in space, first space shuttle flights, first humans on the moon

   • Correct order.

The correct order is: first humans in space, first space shuttle flights, first humans on the moon.
