Elon Musk and Jeff Bezos are in a Twitter argument about rockets

Usually those multi-million dollar rockets are good for one flight.

Musk also pointed out that there have already been rockets that went to the edge of outer space and landed on runways so they could be reused.

Owned by Amazon founder Jeff Bezos, Blue Origin’s goal is to bring customers into sub-orbital space with their rocket, jettisoning a manned capsule at the apex of each flight to afford space tourists a few precious minutes of weightlessness before they are reclaimed by Earth’s gravitational pull.

The launch ended with the spacecraft safely parachuting down to the ground at Blue Origin’s test site near the town of Van Horn, Texas.

Rival rocket business SpaceX, which was started by Tesla Motors CEO Elon Musk, has been trying to land rockets upright as well. Blue Origins’ New Shepard meanwhile, is made up of two components – the crew capsule that carries the astronauts, and the reusable rocket booster that draws power from the BE-3 liquid hydrogen – liquid oxygen engine, which delivers 110,000 pounds of thrust at lift-off.

“Blue Origin’s reusable New Shepard space vehicle flew a flawless mission”. Musk’s company has attempted to land its Falcon 9 rocket on a barge after launch.

On Monday, Blue Origin launched its New Shepard rocket 329,839 feet, or 100.5 kilometers, above its launch site in West Texas, reaching just above the 100-kilometer altitude that is considered the beginning of outer space. “Not anymore”, Bezos said in a statement.

Bezos recorded the event via Twitter, in a style much like Elon Musk. You can watch all of the test flights and landings on YouTube.

Blue Origin, a company owned by Jeff Bezos of Amazon.com earlier said that it would be moving the launch preparation, launch operations and its manufacturing to Cape Canaveral in Florida.

Of course, landing a reusable rocket is still far from easy.

Like another upstart rocket company, Space Exploration Technologies, or SpaceX, Bezos and Blue Origin are betting that reusable rockets can greatly reduce the cost of getting to space.

The technical challenges remain daunting: A vertical touchdown means ensuring that a rocket can survive the heat of re-entering Earth’s atmosphere, navigate toward the landing zone and then decelerate from traveling thousands of miles per hour so it settles in softly – and undamaged.

“It is… important to clear up the difference between “space” and ‘orbit, ‘” he tweeted.
