00:00NASA's Artemis II is the first
00:05crewed lunar mission in over 50 years.
00:08Four astronauts will venture a
00:10around the moon, preparing humanity
00:12for a long-term lunar presence for
00:14scientific discovery.
00:15The 10-day
00:20test flight will demonstrate a range of
00:22deep space exploration capabilities with
00:24crew.
00:25The mission will prove the Orion
00:27spacecraft is ready to keep astronauts
00:29alive.
00:30In deep space and allow the crew and
00:32ground teams to practice operations
00:35is essential to the success of future
00:37missions.
00:41On launch day, the Artemis II crew
00:43suits up, undergoes final checks
00:45and rides in the crew transportation
00:47vehicles to Launch Pad 39B at NASA's
00:49Kennedy Space Station.
00:50Center in Florida.
00:52Stacked on the mobile launcher, NASA's
00:5522-foot-tall SLS or Space Launch System

01:00the crew.
01:01Having made its four-mile journey from
01:02the Vehicle Assembly Building on the
01:04Crawler Trans...
01:05The launch team fills the SLS propellant
01:10tanks...
01:10with over 700,000 gallons of liquid oxygen
01:13and liquid hydrogen and verifies
01:15guidance, communications, and avionics.
01:18At 12 seconds before liftoff, the hydrogen
01:20burn off igniters fire.
01:22About six seconds later, the rocket's
01:23four RS-25...
01:25engines ignite.
01:26When the countdown reaches zero, the
01:28umbilicals retract, giving SLS...
01:30and the crew in Orion the clearance to
01:32begin the journey.
01:35the six-million-pound moon rocket
01:40produces 8.8 million pounds of thrust to
01:42accelerate towards space.
01:4575% of this power comes from the two 17-story
01:48solid rocket boosters.
01:50each producing 3.6 million pounds of thrust.
01:55about two minutes in, the...
02:00boosters are released, their solid propellant
02:02consumed.
02:03The core stage and its RS-25...
02:05engines continue to propel Orion and the crew to space.
02:10after three minutes, the protective fairings surround
02:15Orion's service module are ejected, exposing its solar arrays.
02:20three seconds later, the launch abort system is ejected from Orion.
02:23The crew has safely reached Earth orbit...
02:25though they could still abort using service module engines.
02:30about eight minutes after launch, the SLS core stage engines shut down and the interim
02:35cryogenic propulsion stage or ICPS and Orion separate from the core stage.
02:40Orion and the ICPS are now flying free.
02:45and a second chance to the O.S.
02:46pilot pilot aquilo in the air.
02:48The started off my run,
02:49the SLS core stage is so good on doing it
02:50in the air.
02:51I'm so excited, I'm looking forward to it.
02:52while I'm on and I'm on.
02:53Lots of speed running,
02:54and I'm getting to go on and I'm trying to go on.
02:55and you know it's all about the coming stage,
02:56you know, the last time on our list is set to get on the air.
02:57and the next time on our list of us,
02:58we'll find your astronomerade out.
02:59along the upper list of us,
03:01we'll find it at the end of our list of all of the medals.
03:04and on our list of the medals of the medals we've tested,
03:06we know it's like a new one that's done and
03:08not been there,

04:59The Artemis 2 crew traveled
05:04about 4,600 miles
05:06beyond the moon, becoming the first humans
05:09to lay eyes on
05:09the lunar far side in over 50 years.
05:12Their observations will help
05:14us prepare for
05:14future missions at the moon.
05:17During this period, there will be
05:18an anticipated communication
05:19blackout between mission control
05:21and the spacecraft.
05:23As the crew returns

05:44Before entering the atmosphere, Orion's crew module separates from the service module.
05:4912 thrusters ensure Orion is properly oriented at an altitude of
05:54about 75 miles from Earth's surface.
05:5912.
06:00Orion and
06:04As a crew, enter Earth's atmosphere at a speed of nearly 25,000 mph.
06:09Accelerando a rate up to four times the force of gravity,
06:13the crew will feel four times heavier than they expected.

06:16Orion's heat shield protects the spacecraft from temperatures of about 5,000...
06:19...degrees Fahrenheit, about half as hot as the surface of the sun.
