Asked how much passengers would pay, Mr. Bezos said he did not know yet, but he predicted ticket prices would decline as spaceflight became more common. (Hundreds of people have already put down deposits to reserve places on similar commercial trips on Virgin Galactic that could cost $250,000 a ticket, although that company’s spaceplane has yet to take anyone up.)

New Shepard is a modest start for Mr. Bezos’s ambitions to tap into the nascent space tourism market. It is a single-stage booster with a capsule on top that is designed to carry six passengers at a time on trips of about 10 to 11 minutes.

There will not be a Blue Origin crew on the spacecraft. Passengers wearing sleek jumpsuits will be able to peer out what the company says will be the largest windows in space, taking up about one-third of the surface area of the dome.

About 12 feet in diameter, the passenger capsule holds six black seats that resemble recliners, with panels offering details about altitude and other features of a trip.

The engine that powers the booster produces up to about 110,000 pounds of thrust.

On ascent, passengers will experience forces of about 3 Gs, about three times the normal force of gravity that humans experience on earth. When the booster reaches a certain altitude, the capsule will detach and coast above the Karman line, which is 62 miles above sea level, officially entering into space.

There, the passengers will experience about four to five minutes of weightlessness. They can unbuckle their harnesses and do somersaults, if desired, in the padded-dome interior.
