NASA tracks large space debris and used to publish a monthly (as I recall) list of all the space junk orbiting the earth. You don’t want to send a rocket up only to have the payload collide with something. In order to stay in orbit, the spacecraft/satellite needs to be moving very fast or its orbit will gradually deteriorate. Satellites have boosters to keep them in the right spot and there is some evidence of satellite refueling missions.
Without a faster than light drive, I think mankind will be staying on earth. And even if a breakthrough occurred tomorrow which would allow us to travel to the nearest star system or habitable planet in hours, it would be wise to do an unmanned recon first.
