00:00NASA's Artemis II is the first crewed lunar mission in over 50 years.
00:08Four astronauts will venture around the moon, preparing humanity for a long-term lunar presence
00:13for scientific discovery and exploration.
00:19The 10-day test flight will demonstrate a range of deep space exploration capabilities
00:24with crew.
00:25The mission will prove the Orion spacecraft is ready to keep astronauts alive in deep
00:30space and allow the crew and ground teams to practice operations essential to the success
00:36of future missions.
00:41On launch day, the Artemis II crew suits up, undergoes final checks, and rides in the crew
00:46transportation vehicles to Launch Pad 39B at NASA's Kennedy Space Center in Florida.
00:52Stacked on the mobile launcher, NASA's 322-foot-tall SLS, or Space Launch System, rocket with the
00:58Orion spacecraft awaits the crew, having made its four-mile journey from the Vehicle Assembly
01:03Building on the crawler-transporter to the pad.
01:07The launch team fills the SLS propellant tanks with over 700,000 gallons of liquid oxygen
01:13and liquid hydrogen and verifies guidance, communications, and avionics.
01:18At 12 seconds before liftoff, the hydrogen burn-off igniters fire.
01:22Six seconds later, the rocket's four RS-25 engines ignite.
01:26When the countdown reaches zero, the umbilicals retract, giving SLS and the crew in Orion
01:31the clearance to begin the journey.
01:38The six-million-pound moon rocket produces 8.8 million pounds of thrust to accelerate
01:43towards space.
01:4475 percent of this power comes from the two 17-story solid rocket boosters, each producing
01:503.6 million pounds of thrust.
01:59About two minutes in, the boosters are released, their solid propellant consumed.
02:03The core stage and its RS-25 engines continue to propel Orion and the crew to space.
02:12After three minutes, the protective fairings surrounding Orion's service module are ejected,
02:17exposing its solar arrays.
02:19Six seconds later, the launch abort system is ejected from Orion.
02:23The crew has safely reached Earth orbit, though they could still abort using service module
02:27engines.
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.
02:52Orion's four solar arrays deploy, powering the spacecraft and charging its batteries
02:56for when it moves out of direct sunlight during the journey to the moon and back.
03:04After a 90-minute orbit, the engine of the rocket's upper stage, or ICPS, ignites to
03:09raise Orion to a high-Earth orbit.
03:13The Artemis II crew and mission control in Houston then begin a nearly 24-hour systems
03:17check while the astronauts are still relatively close to Earth, familiarizing themselves with
03:22their new home for the next several days.
03:39Once in high-Earth orbit, Orion separates from the upper stage.
03:43The expended ICPS and Orion stage adapter serve as a target for a manual handling test
03:49called the Proximity Operations Demonstration, preparing future crews for rendezvous, docking,
03:54and undocking with other spacecraft.
03:58During the demonstration, Artemis II astronauts use cameras and line-of-sight through Orion's
04:03windows to pilot the spacecraft as they approach and back away, assessing Orion's handling
04:08qualities, hardware, and software.
04:16Following the demonstration, spacecraft data is collected to verify system performance,
04:20such as life support, communications, and navigation, ensuring Orion and the crew are
04:25ready for the voyage ahead.
04:34About 23 hours later, Orion's service module performs the Translunar Injection Burn, or
04:39TLI, pushing Orion out of Earth orbit and on an approximately four-day trip to the moon.
04:44Ultimately, the crew's figure-eight flight path extends more than 230,000 miles from
04:50Earth.
04:52During the trip, the astronauts continue to evaluate the spacecraft's systems and practice
04:56emergency procedures like testing the radiation shelter.
05:03The Artemis II crew travels about 4,600 miles beyond the moon, becoming the first humans
05:09to lay eyes on the lunar far side in over 50 years.
05:13Their observations will help us prepare for future missions at the moon.
05:17During this period, there will be an anticipated communication blackout between mission control
05:22and the spacecraft.
05:24As the crew returns from the far side of the moon, Orion is drawn home by Earth's gravity
05:28in a free-return trajectory, ensuring a fuel-efficient four-day trip.
05:43Before entering the atmosphere, Orion's crew module separates from the service module.
05:51Twelve thrusters ensure Orion is properly oriented at an altitude of about 75 miles
05:56from Earth's surface.
06:04Orion and the crew enter Earth's atmosphere at a speed of nearly 25,000 mph, decelerating
06:10at a rate up to four times the force of gravity, the crew will feel four times heavier than
06:14they do on Earth.
06:17Orion's heat shield protects the spacecraft from temperatures of about 5,000 degrees Fahrenheit,
06:21about half as hot as the surface of the sun.
06:26To slow its descent, Orion begins a precise deployment sequence of 11 parachutes.
06:31Three forward bay cover parachutes first separate the protective thermal cover that sits over
06:36the chutes.
06:38Two drogues slow and stabilize the crew module, then cut free.
06:43Three pilot chutes lift the three main parachutes, deployed at an altitude of 9,000 feet and
06:47traveling 130 mph.
06:50These chutes slow the crew module to a speed of less than 20 mph.
06:57After traveling more than 595,000 nautical miles, Orion splashes down in the Pacific
07:03Ocean, about 50 nautical miles from the California coast, just 16 minutes after entering Earth's
07:08atmosphere.
07:10After splashdown, a recovery team that includes the U.S. Navy, Air Force, and NASA approaches
07:14Orion.
07:15The team ensures it's safe for the crew to exit before divers help the astronauts onto
07:19an inflatable front porch, hoist them into helicopters, and fly to the recovery ship.
07:25Orion is towed into the ship for its return to Kennedy Space Center.
07:29Their mission complete, the crew is flown back to land and step on solid ground for
07:33the first time in 10 days.
07:36This is Artemis II.
