This time, Jeffrey P. Bezos’ rocket went up — and it came down in one piece.

Mr. Bezos, the founder of Amazon, has been investing some of his wealth in space dreams, establishing a rocket company called Blue Origin. On Monday, Blue Origin launched its New Shepard rocket, named after Alan Shepard, the first American to reach space in a similar suborbital flight in 1961.

The rocket lofted a capsule that is to eventually carry paying passengers on suborbital jaunts to a height of 329,839 feet, or 100.5 kilometers, above its launch site near Van Horn in West Texas. That is just above the 100-kilometer altitude that is considered the beginning of outer space.

The capsule descended to the ground under parachutes 11 minutes after blasting off. The rocket itself turned around and, firing its engines again, set back down at the launchpad at 4.4 miles per hour — faster than a person strolling, but gentle enough to prevent damage. It landed less than five feet from its target.

“It was a totally nominal flight,” Mr. Bezos said in an interview. “We’re walking on cloud nine. There wasn’t a dry eye in the house.”
