Answer 1

Answer: develop technology and resources capable of sending the general population into space on a regular basis

Step-by-step explanation:

At the present moment, humanity lacks the capacity to send just about anyone into space on a regular basis. Space missions are quite expensive and require a high degree of expertise from the people who pilot the vessels going into space.

Hopefully this will change in the near future as companies like SpaceX aim to make space travel considerably cheaper and easier so that regular people can be able to go to space.
