What will Elon Musk and Richard Branson do about Jeff Bezos flying into space?
 Istock  Jeff Bezos , the founder of Amazon and the CEO of the space launch company Blue Origin, caused a social media sensation when he made the following announcement of Instagram:  Ever since I was five years old, Ive dreamed of traveling to space. On July 20th, I will take that journey with my brother. The greatest adventure, with my best friend.  Bezos proposes to achieve several things besides fulfilling a childhood dream shared by uncounted people on planet Earth. He will prove the safety of the New Shepard rocket ship by betting his and his brothers lives on it. The Amazon founder will change his personal brand from that of a monopolist into a private astronaut pushing back the envelope of the final frontier. Finally, Bezos will show up his rival, Elon Musk, whose rockets regularly go into orbit, but who has not yet personally flown into space. However, Virgin Galactics Richard Branson may steal a march on Bezos. The New Shepard rocket, which has flown unpiloted over a dozen times in the skies over Texas, is due to make its first flight with humans on board on the anniversary of the Apollo 11 moon landing. One of the seats will be occupied by the winner of an auction, the proceeds to which will go to charity. Bezos and his brother will occupy two of the other seats. The New Shepard passengers will fly just past the edge of space to experience a few minutes of microgravity and the greatest view of Earth ever before descending back to soft land on Earth. Bezos will not be the first rich guy to fly into space on his own dime. Dennis Tito has that honor, thanks to a flight in 2001 to the ISS arranged by Space Adventures on board a Russian Soyuz. Since then, a number of the well-heeled and adventurous, including Iranian American businesswoman Anousheh Ansari and computer gaming magnate Richard Garriott, have taken similar rides. But Bezos will be the first to ride in a rocket ship he developed and owns. The bitter rivalry between the two space entrepreneurs is no secret. Thus far, Musk has been beating Bezos hands down on both business and personal branding. SpaceX rockets regularly take both cargo and people into low Earth orbit. Musk has won the NASA contract to build the first crewed lunar lander in over 50 years. Musk has proven to be pretty endearing and cool with his recent stint as a Saturday Night Live guest host. Musk has used the Crew Dragon to start a space tourism service. A fundraising flight, called Inspiration 4, will be the first off the launch pad. Meanwhile, Axiom has arranged for four private space flights to the International Space Station on board the Crew Dragon. A few minutes suborbital hop is one thing. A week-long or longer voyage to the International Space Station (ISS) is quite another. In theory, Musk could grab a seat on one of those flights and thus do Bezos one better in the rich space adventurer game. He is, after all, running both a space launch company and an electric car company, among other enterprises. Then again, Musk also has harbored dreams of space flight from childhood. He plans to build a Mars colony and spend his later years there. Musk is building a rocket called the Starship that will fulfill that ambition. Perhaps a ride to-and-from the ISS will be a practice run for the months-long interplanetary voyage to Mars, followed by the rest of his life on the Red Planet. Musk cannot pull such a flight off before Bezos. However, Richard Branson might, perhaps on July 4.
