The difference between this mission and previous ones is that it is comprised of only four civilians or space tourists, who have dreamed of this moment for years. The rocket's takeoff was streamed on YouTube. It will now remain there for approximately three days, meaning that during this time it will orbit the Earth approximately 50 times before returning.
As for the special design with which the Dragon Crew was built, a glass dome was added so that astronauts could see the Earth from almost 600 kilometers high. This adds to one of the achievements of Elon Musk's company, in addition to reusing rockets as much as possible as a way to save costs.
