Heading east, the rocket will surpass the pace of sound in just a little over a minute. After hovering by way of the stratosphere, New Glenn will shut down its seven booster engines and shed its first stage just a little greater than 3 minutes into the flight. Twin BE-3U engines, burning liquid hydrogen, will ignite to complete the job of sending the ESCAPADE satellites towards deep area. The rocket's trajectory will ship the satellites towards a gravitationally-stable location past the Moon, referred to as the L2 Lagrange level, the place it is going to swing right into a loosely-bound loiter orbit to attend for the fitting time to go for Mars.
In the meantime, the New Glenn booster, itself measuring practically 20 tales tall, will start maneuvers to go towards Blue Origin's restoration ship floating a number of hundred miles downrange within the Atlantic Ocean. The ultimate a part of the descent will embody a touchdown burn utilizing three of the BE-4 engines, then downshifting to a single engine to regulate the booster's landing on the touchdown platform, dubbed “Jacklyn” in honor of Bezos' late mom.
The launch timeline for New Glenn's second mission.

Blue Origin
New Glenn's inaugural launch initially of this 12 months was successful, however the booster's descent didn't go properly. The rocket was unable to restart its engines, and it crashed into the ocean.
“We've integrated quite a lot of adjustments to our propellant administration system, some minor {hardware} adjustments as properly, to extend our probability of touchdown that booster on this mission,” mentioned Laura Maginnis, Blue Origin's vice chairman of New Glenn mission administration. “That was the first schedule driver that sort of took us from from January to the place we're immediately.”
Blue Origin officers are hopeful they will land the booster this time. The corporate's optimism is sufficient for officers to have penciled in a reflight of this explicit booster on the very subsequent New Glenn launch, slated for the early months of subsequent 12 months. That launch is because of ship Blue Origin's first Blue Moon cargo lander to the Moon.
“Our No. 1 goal is to ship ESCAPADE safely and efficiently on its approach to L2, after which finally on to Mars,” Maginnis mentioned in a press convention Saturday. “We are also planning and eager to land our booster. If we don't land the booster, that's OK. Now we have a number of extra autos in manufacturing. We're excited to see how the mission performs out tomorrow.”
Tracing a kidney bean
ESCAPADE's path by way of area, relative to the Earth, has the peculiar form of a kidney bean. On the earth of astrodynamics, that is referred to as a staging or libration orbit. It's a approach to maintain the spacecraft on a steady trajectory to attend for the chance to go to Mars late subsequent 12 months.
