00:00Impulsada por el Space Launch System, el cohete más potente de la NASA, con más de 39 meganewtons de empuje,
00:09la misión Artemis II logró llevar a su tripulación más allá de la órbita terrestre.
00:13Con casi 100 metros de altura y tecnología heredada del transbordador espacial,
00:19el SLS concentra décadas de innovación aeroespacial.
00:23Cada fase de su operación, desde el encendido de sus motores hasta la separación de sus propulsores,
00:29fue clave para alcanzar la trayectoria correcta.
00:35NASA's Artemis II is the first crewed lunar mission in over 50 years.
00:41Four astronauts will venture around the moon, preparing humanity for a long-term lunar presence,
00:46for scientific discovery and exploration.
00:51The 10-day test flight will demonstrate a range of deep space exploration capabilities with crew.
00:57The mission will prove the Orion spacecraft is ready to keep astronauts alive in deep space
01:03and allow the crew and ground teams to practice operations essential to the success of future missions.
01:13On launch day, the Artemis II crew suits up, undergoes final checks,
01:17and rides in the crew transportation vehicles to Launch Pad 39B at NASA's Kennedy Space Center in Florida.
01:25Stacked on the mobile launcher, NASA's 322-foot-tall SLS, or Space Launch System, rocket with the Orion spacecraft awaits
01:32the crew,
01:33having made its four-mile journey from the vehicle assembly building on the crawler transporter to the pad.
01:39The launch team fills the SLS propellant tanks with over 700,000 gallons of liquid oxygen and liquid hydrogen
01:46and verifies guidance, communications, and avionics.
01:49At 12 seconds before liftoff, the hydrogen burn-off igniters fire.
01:54About six seconds later, the rocket's four RS-25 engines ignite.
01:58When the countdown reaches zero, the umbilicals retract, giving SLS and the crew in Orion the clearance to begin the
02:05journey.
02:10The six-million-pound moon rocket produces 8.8 million pounds of thrust to accelerate towards space.
02:1775% of this power comes from the two 17-story solid rocket boosters, each producing 3.6 million pounds
02:25of thrust.
02:31About two minutes in, the boosters are released, their solid propellant consumed.
02:35The core stage and its RS-25 engines continue to propel Orion and the crew to space.
02:45After three minutes, the protective fairings surrounding Orion's service module are ejected, exposing its solar arrays.
02:52Six seconds later, the launch-abort system is ejected from Orion.
02:55The crew has safely reached Earth orbit, though they could still abort using service module engines.
03:02About eight minutes after launch, the SLS core stage engines shut down and the interim cryogenic propulsion stage, or ICPS,
03:10and Orion separate from the core stage.
03:12Orion and the ICPS are now flying free.
03:24Orion's four solar arrays deploy, powering the spacecraft and charging its batteries for when it moves out of direct sunlight
03:31during the journey to the moon and back.
03:36After a 90-minute orbit, the engine of the rocket's upper stage, or ICPS, ignites to raise Orion to a
03:43high Earth orbit.
03:45The Artemis 2 crew and mission control in Houston then begin a nearly 24-hour systems check while the astronauts
03:51are still relatively close to Earth, familiarizing themselves with their new home for the next several days.
04:11Once in high Earth orbit, Orion separates from the upper stage.
04:15The expended ICPS and Orion stage adapter serve as a target for a manual handling test called the Proximity Operations
04:23Demonstration, preparing future crews for rendezvous, docking, and undocking with other spacecraft.
04:30During the demonstration, Artemis 2 astronauts use cameras and line of sight through Orion's windows to pilot the spacecraft as
04:37they approach and back away, assessing Orion's handling qualities, hardware, and software.
04:48Following the demonstration, spacecraft data is collected to verify system performance, such as life support, communications, and navigation, ensuring Orion
04:57and the crew are ready for the voyage ahead.
05:06About 23 hours later, Orion's service module performs the Translunar Injection Burn, or TLI, pushing Orion out of Earth orbit
05:14and on an approximately four-day trip to the moon.
05:17Ultimately, the crew's figure-eight flight path extends more than 230,000 miles from Earth.
05:24During the trip, the astronauts continue to evaluate the spacecraft's systems and practice emergency procedures, like testing the radiation shelter.
05:35The Artemis 2 crew travels about 4,600 miles beyond the moon, becoming the first humans to lay eyes on
05:42the lunar far side in over 50 years.
05:45Their observations will help us prepare for future missions at the moon.
05:49During this period, there will be an anticipated communication blackout between mission control and the spacecraft.
05:56As the crew returns from the far side of the moon, Orion is drawn home by Earth's gravity in a
06:01free-return trajectory, ensuring a fuel-efficient four-day trip.
06:16Before entering the atmosphere, Orion's crew module separates from the service module.
06:23Twelve thrusters ensure Orion is properly oriented at an altitude of about 75 miles from Earth's surface.
06:37Orion and the crew enter Earth's atmosphere at a speed of nearly 25,000 miles per hour.
06:42Decelerating at a rate up to four times the force of gravity, the crew will feel four times heavier than
06:47they do on Earth.
06:49Orion's heat shield protects the spacecraft from temperatures of about 5,000 degrees Fahrenheit, about half as hot as the
06:55surface of the sun.
06:58To slow its descent, Orion begins a precise deployment sequence of 11 parachutes.
07:04Three forward bay cover parachutes first separate the protective thermal cover that sits over the chutes.
07:11Two drogues slow and stabilize the crew module, then cut free.
07:15Three pilot chutes lift the three main parachutes, deployed at an altitude of 9,000 feet and traveling 130 miles
07:22per hour.
07:22These chutes slow the crew module to a speed of less than 20 miles per hour.
07:29After traveling more than 595,000 nautical miles, Orion splashes down in the Pacific Ocean, about 50 nautical miles from
07:37the California coast, just 16 minutes after entering Earth's atmosphere.
07:42After splashdown, a recovery team that includes the U.S. Navy, Air Force, and NASA approaches Orion.
07:48The team ensures it's safe for the crew to exit before divers help the astronauts onto an inflatable front porch,
07:54hoist them into helicopters, and fly to the recovery ship.
07:58Orion is towed into the ship for its return to Kennedy Space Center.
08:01Their mission complete, the crew is flown back to land and step on solid ground for the first time in
08:0710 days.
08:08We'll see you next time.
