which list gives key events regarding the exploration of space in the correct order, beginning, with the earliest?

Question

First humans on the moon, first lander on mars, first space shuttle flight.

First humans on the moon, first humans on mars, first launching of the international space station

First space shuttle flight, Hubble space telescope, last humans on the moon

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

Answer 1

To order the key events regarding the exploration of space chronologically, we need to 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 space shuttle flight: The first space shuttle, Columbia (STS-1), flew on April 12, 1981.
3. First humans on the moon: Neil Armstrong and Buzz Aldrin landed on the moon during Apollo 11 on July 20, 1969.
4. First lander on Mars: Viking 1 successfully landed on Mars on July 20, 1976.
5. Hubble Space Telescope: Launched on April 24, 1990.
6. First humans on Mars: As of my last knowledge update in October 2023, this event has not yet taken place.
7. Launching of the International Space Station: The first module, Zarya, was launched on November 20, 1998.
8. Last humans on the moon: The last crewed Apollo mission was Apollo 17 in December 1972.

With this information, we can analyze the lists:

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, first launching of the international space station (Incorrect order)
3. First space shuttle flight, Hubble space telescope, last humans on the moon (Incorrect order)
4. First humans in space, first space shuttle flights, first humans on the moon (Correct order)

So, the correct chronological order is found in the fourth list:

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