The issues we’d be facing in space range from getting lost to running our of power. We’d need to have a way to grow food in space, prolong human life for space travel, or make traveling much faster. Then we’d have to solve the issues of communications, we would have to call back home to Earth no matter how far away we are. Finally, we would need a force field. This seems pointless, however, space is a very hostile place with rays to space rockets hitting your craft. We would have to A find a way to protect the ship or B have a 24/7 mechanic.
