Let us take a look at billionaires eyeing space as the next entrepreneurial frontier.
The first space race was between the USA and USSR amid the cold war as both sides looked at space as the final frontier. The US emerged victorious after it successfully landed its astronauts on the moon.
The current round of competition sees various parties vying to become the first agency to land a human on Mars.
There is also an ongoing competition between Asian powerhouses of India, China and Japan.
Another interesting race is shaping up in the west that sees billionaires and entrepreneurs trying to outdo each other with various space missions.
A key player in this race of billionaires is Elon Musk. The SpaceX founder has already announced his intention to send tourists into space by the end of this year.
Jeff Bezos who founded Blue Origin is planning to send a vehicle to space next month itself. The billionaire has already announced that he along with his brother will be part of the first-ever suborbital sightseeing trip.
Richard Branson, who founded Virgin Galactic, had earlier claimed that they would send the first tourist to space in 2009 itself.
Google co-founder Sergey Brin spent a fortune back in 2008 to book a ticket on a private space flight.
The race between these private space companies can revolutionise the way we look at space exploration.
