The first earthling to orbit our planet was just two years old. Her name was Laika, and she was picked up in the streets of Mosc
ow in 1957, just a few days before the launch of Sputnik 2. Laika was a terrier mutt, and her flight aboard Sputnik 2 paved the way for space exploration during a time when scientists weren’t sure if spaceflight was safe for living organisms. Since then, humans have orbited Earth and even walked on the moon. Currently NASA is planning a mission to send astronauts to a nearby asteroid, and commercial companies are planning civilian missions to the moon. Unmanned space probes have traveled past Neptune and Pluto to the outer edge of our solar system and entered interstellar space. Space travel has come a long way since Laika, but there are still many celestial bodies waiting to be explored. What do you think will be the biggest space mission of the twenty-first century? What challenges do you anticipate that the humans or space probes will experience on this journey? What specific accommodations or technological advancements will be needed to make the mission successful?
i think since we have gone as far as our solar system boundaries the next big thing to achieve is to actually travel to another solar system, the challenge that would face anyone trying to reach another solar system is the distance, the distance is too long to cut with a speed slower than the speed of light in fact even the speed of light is not convenient for someone to travel and reach the other side before he dies and nothing can reach or exceed the speed of light because then they would lose their mass to energy, two proposed technologies to get past that is hibernation which is keeping the body alive in a sleeping state using a break through technology the other would be using a wormhole but we don't know of any in the moment
There are three domains of life: Bacteria (also known as Eubacteria), Archaea, and Eukarya.

Here are other major differences between the three domains.
