Heading into space is in.

Space has become an increasingly hot investment opportunity, and the news coming out of Blue Origin, Amazon (AMZN) CEO Jeff Bezos' space exploration company, has only added fuel to the flame.

The company's senior vice president Rob Meyerson told listeners at an Amazon-backed summit Sunday that Blue Origin expects to start selling tickets for commercial flights in 2019, according to a SpaceNews report.

Meyerson might have just put Blue Origin on an accelerated timetable to get its New Shepard sub-orbital rockets ready for commercial use, but interest across the board has increased for companies like Blue Orbital, Virgin Galactic and Tesla (TSLA) CEO Elon Musk's SpaceX as the private sector has taken the reigns on trying to profit off of space.

For example, Boeing (BA) shares have been on fire the past year in part because of its efforts to help the U.S. back into space. 

President Trump has also added to the space-exploration fervor with his call last week for the creation of a sixth branch of the U.S. armed forces, which he affectionately dubbed "Space Force." The president's directive for the Pentagon to pour more resources toward this new force prompted Morgan Stanley to give their support in the plan from an investment standpoint.

The bank values space as the next trillion-dollar industry and anticipates it will enhance the U.S.'s technology capabilities in the future as well as providing more security for the country's national defense, according to a research note.

Morgan Stanley plans on monitoring over 100 private companies that deal in some aspect of the space industry for investment opportunities going forward, according to the note.
