# NASA's Artemis II mission successfully launched from Kennedy Space Center’s Launch Complex 39B in Florida at 6:35 p.m. EDT. *aerospace · news · 2026-04-01 · The Economic Times* ## Key points - NASA's Artemis II is the first crewed mission to deep space in over 50 years. - The Orion spacecraft, named Integrity, carries three NASA astronauts and one Canadian astronaut. - Artemis II's launch used over 8.8 million pounds of thrust from four RS-25 engines and boosters. - Mission procedures included super-cold propellant conditioning and fairing jettison before translunar injection. - The Interim Cryogenic Propulsion Stage will propel Orion on its path beyond Earth's orbit toward the Moon. Synopsis Artemis launch live: NASA's Artemis II mission successfully launched from Florida, marking the first crewed flight of the Artemis program and humanity's return to deep space in over 50 years. The Orion spacecraft, carrying four astronauts, embarked on a roughly 10-day journey around the Moon and back, testing critical systems for future lunar exploration. Artemis launch live: NASA’s Artemis II mission successfully launched from Kennedy Space Center’s Launch Complex 39B in Florida at 6:35 p.m. EDT, marking the first crewed flight of the Artemis program. Artemis Launch Live: NASA's First Crewed Moon Mission in Over 50 Years The Orion spacecraft, named Integrity, carried NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, along with Canadian Space Agency astronaut Jeremy Hansen, on a roughly 10-day journey around the Moon and back. Rocket Launch Today Live: How Artemis II Lifted Off The mission began with the twin solid rocket boosters igniting, generating over 8.8 million pounds of thrust with the support of the four RS-25 engines, as per a NASA report. This immense power lifted the 5.75-million-pound rocket off the pad, beginning its historic trek beyond Earth’s atmosphere. Shuttle Launch to the Moon: Orion’s Journey As Orion climbed, umbilicals detached, and protective fairings jettisoned, revealing the spacecraft to the vast expanse of space. The booster separation soon followed, reducing weight and allowing the SLS core stage to continue propelling Orion toward orbit, as per the NASA report. NASA Launch Live: Countdown and Preparations Explained The Artemis II crew’s day began hours earlier with traditional NASA rituals and meticulous preparations. After a wake-up call at 9:25 a.m., the astronauts donned their Orion Crew Survival System suits, performed leak and communication checks, and boarded Orion with the aid of the closeout crew.

The crew even took part in a pre-launch card game, a time-honored tradition intended to bring good luck, as per the NASA report. Launch to the Moon: Artemis II Flight Overview Engineers and flight teams orchestrated a careful countdown, managing fueling, pressurization, and system checks to ensure every stage of the rocket was flight-ready. From liquid hydrogen and oxygen chilldowns to topping and replenish operations for the SLS core and interim cryogenic propulsion stages, teams maintained precise conditions for the super-cold propellants essential for liftoff and translunar injection, as per the NASA report. As Orion soared above the densest layers of Earth’s atmosphere, protective structures jettisoned, signaling that the spacecraft was fully exposed and ready to continue its journey. The next milestone, core stage separation and ignition of the Interim Cryogenic Propulsion Stage, will further propel Artemis II on its trajectory toward the Moon, testing systems and operations for humanity’s next steps in space exploration, as per the NASA report. Live Rocket Launch: Artemis II Journey Begins This launch not only marks a monumental achievement in NASA’s Artemis program but also the first time in over five decades that humans have left low Earth orbit to venture toward deep space, setting the stage for future lunar exploration and missions to Mars.
