CAPE CANAVERAL, Fla. (AP) -- Blue Origin launched its massive new rocket on its first test flight Thursday, sending up a prototype satellite to orbit thousands of miles above Earth.

Named after the first American to orbit Earth, the New Glenn rocket blasted off from Florida, soaring from the same pad used to launch NASA's Mariner and Pioneer spacecraft a half-century ago.

Years in the making with heavy funding by Amazon founder Jeff Bezos, the 320-foot (98-meter) rocket carried an an experimental platform designed to host satellites or release them into their proper orbits. All seven main engines fired at liftoff as the rocket blazed through the predawn sky, drawing cheers from spectators lining the nearby beaches. Company employees erupted in shouts and frenzied applause once the craft successfully orbit 13 minutes later, a feat that drew quick praise from SpaceX's Elon Musk.

Bezos -- taking part in the launch from Mission Control -- declined to disclose his personal investment in the program. He said he does not see Blue Origin in a competition with Elon Musk's SpaceX, long the rocket-launching dominator.

He stood much of the time at his seat in Mission Control, looking anxious and happy at the same time.

"Congratulations on reaching orbit on the first attempt!" Musk said via X.

For this test, the satellite was expected to remain inside the second stage while circling Earth. The mission was expected to last six hours, with the second stage then placed in a safe condition to stay in a high, out-of-the-way orbit in accordance with NASA's practices for minimizing space junk.

The first-stage booster missed its landing on a barge in the Atlantic minutes after liftoff so it could be recycled, but the company stressed that the more important goal was for the test satellite to reach orbit. Bezos said before the flight it was "a little crazy" to even try to land the booster on the first try.

"What a fantastic day," Blue Origin's launch commentator Ariane Cornell, said.

New Glenn was supposed to fly before dawn Monday, but ice buildup in critical plumbing caused a delay. The rocket is built to haul spacecraft and eventually astronauts to orbit and also the moon.

Founded 25 years ago by Bezos, Blue Origin has been launching paying passengers to the edge of space since 2021, including himself. The short hops from Texas use smaller rockets named after the first American in space, Alan Shepard. New Glenn, which honors John Glenn, is five times taller.

Blue Origin poured more than $1 billion into New Glenn's launch site, rebuilding historic Complex 36 at Cape Canaveral Space Force Station. The pad is 9 miles (14 kilometers) from the company's control centers and rocket factory, outside the gates of NASA's Kennedy Space Center.

Blue Origin envisions six to eight New Glenn flights this year, if everything goes well, with the next one coming up this spring.

"There's room for lots of winners" Bezos said from the rocket factory over the weekend, adding that this was the "very, very beginning of this new phase of the space age, where we're all going to work together as an industry ... to lower the cost of access to space."

New Glenn is the latest in a series of big, new rockets to launch in recent years, including United Launch Alliance's Vulcan, Europe's upgraded Ariane 6 and NASA's Space Launch System or SLS, the space agency's successor to the Saturn V for sending astronauts to the moon.

The biggest rocket of all, at approximately 400 feet (123 meters), is SpaceX's Starship. Musk said the seventh test flight of the full rocket could occur later Thursday from Texas. He hopes to repeat what he pulled off in October, catching the returning booster at the launch pad with giant mechanical arms.

Starship is what NASA plans to use to land astronauts on the moon later this decade. The first two moon landings under the space agency's Artemis program, which follows the Apollo missions of the 1960s and 1970s, will see crews descending from lunar orbit to the surface in Starships.

Blue Origin's lander, dubbed Blue Moon, will make its debut on the third lunar touchdown by astronauts.

NASA Administrator Bill Nelson pushed for competing moon landers similar to the strategy to hire two companies to ferry astronauts to and from the International Space Station. Nelson will step down when President-elect Donald Trump takes office on Monday.

Trump has tapped tech billionaire Jared Isaacman to run NASA. Isaacman, who has twice rocketed into orbit on his own privately financed SpaceX flights, must be approved by the Senate.

New Glenn's debut was supposed to send twin spacecraft to Mars for NASA. But the space agency pulled them from last October's planned flight when it became clear the rocket wouldn't be ready in time. They will still fly on a New Glenn rocket, but not until spring at the earliest. The two small spacecraft, named Escapade, are meant to study the Martian atmosphere and magnetic environment while orbiting the red planet.
