There is already news about the tough competition that Jeff Bezos' company Blue Origin is giving to Virgin Galactic wherein it was mentioned that Blue Origin is a vertical rocket and has more window space as compared to VSS Unity. It was also stated that Blue Origin's ticket is lesser as compared to Virgin's. However, Virgin Galactic stands unaffected and anticipates to launch almost 400 spaceflights each year to the privileged few who can afford them. 

But there is more to the space race. Besides the news-making spaceflights of the two space trailblazers and billionaires, the space race throne is been divided among three billionaires, with Elon Musk being the third space enthusiast. Elon Musk's company SpaceX is also a highly successful venture and has already delivered a few astronauts to the International Space Station. 

However, the space race seems to be a highly burdening ambition for the Earth's atmosphere and climate. During launch, rockets can emit between 4 to 10 times more nitrogen oxides than Drax, the largest thermal power plant in the UK, over the same time period. CO2 emissions on a spaceflight will be between 50 and 100 times more than the one to three tonnes of emissions that are generated per passenger on a long-haul airplane flight.

With this, it can only be concluded that the technology must improve into a more sustainable technology which can be utilized by the rockets. International regulators also need to keep up with this nascent yet highly damaging industry that is burgeoning rapidly with billionaire entrepreneurs pouring their money into the lucrative industry.
