Commercial space exploration can advance at the fast pace of Internet commerce only if the cost is reduced through advances in reusable rockets, Inc. Chief Executive Officer Jeff Bezos said.

The e-commerce pioneer drew comparisons between the growth of his online retail business over the past 20 years and his investments in space exploration with his company Blue Origin LLC.

Amazon grew so quickly because key infrastructure was already in place, such as delivery through the postal service, phone lines for Internet access and credit card payments. The missing piece for space travel is low-cost launches, which will only happen when rockets can be reused like airplanes, Bezos said Tuesday in his first address at the annual Space Symposium in Colorado Springs, Colorado.

“What’s important to me is lowering the cost of getting to space,” he said. “I want to see millions of people living and working in space.”

Beyond Tourism

Blue Origin has successfully launched and landed the same rocket three times as it seeks to challenge billionaire Elon Musk’s Space Exploration Technologies Corp. Musk has dismissed some of Bezos’s accomplishments as old news. The annual space symposium, which draws thousands of worldwide enthusiasts, gave Bezos a chance to highlight his accomplishments and emphasize that Blue Origin’s mission is to become more than a space tourism company.

Bezos and Musk are not the only billionaires attracted to space exploration. Yuri Milner, the Russian investor who has backed various space ventures, said Tuesday at an event in New York that he would give $100 million to Breakthrough Starshot, a research project that will try to develop tiny, unmanned spaceships to search the universe for intelligent life over the next decade.

Beyond its rocket program, Blue Origin is joining with United Launch Alliance to create a domestically built BE-4 engine capable of launching rockets by 2019, highlighting its position as a contender in the commercial space race, said Paul Kostek, a systems engineer with GE Aviation.

“This project will expand their reach from just a niche tourism company to major player in future system development,” Kostek said. “Success is success and this shows they have become a major engineering and manufacturing company.”
