Artemis II Lifts Off for Historic Lunar Mission
NASAs Artemis II mission launched successfully on April 5, 2026, at 12:34 PM EDT from Launch Complex 39B at Kennedy Space Center in Florida, sending four astronauts on a trajectory to orbit the Moon. The mission marks humanitys first crewed journey beyond low Earth orbit since Apollo 17 in December 1972 — a gap of more than 53 years.
The Space Launch System (SLS) rocket, the most powerful rocket ever launched by NASA, performed flawlessly during its ascent, delivering the Orion spacecraft into a precise trans-lunar injection orbit approximately two hours after liftoff.
Meet the Crew
The four-person Artemis II crew represents a milestone in diversity and international cooperation:
- Commander Reid Wiseman (NASA) — U.S. Navy Captain, veteran of ISS Expedition 41, making his second spaceflight
- Pilot Victor Glover (NASA) — U.S. Navy Captain, who will become the first Black astronaut to fly beyond low Earth orbit
- Mission Specialist Christina Koch (NASA) — Record holder for the longest single spaceflight by a woman (328 days on ISS)
- Mission Specialist Jeremy Hansen (CSA) — Royal Canadian Air Force Colonel, the first Canadian to fly to the Moon
“Today we open a new chapter in human exploration. This crew represents the best of what America and our international partners can achieve together. We are going back to the Moon, and this time we are going to stay.” — NASA Administrator Bill Nelson
Mission Profile
Artemis II is a 10-day mission that will take the Orion spacecraft around the far side of the Moon and back to Earth. Unlike the Artemis I uncrewed test flight in 2022, this mission will carry humans but will not enter lunar orbit or land on the surface. The mission objectives include:
- Testing life support systems with a full crew complement
- Validating navigation and communication systems in deep space
- Conducting a close flyby of the lunar surface at approximately 6,400 miles altitude
- Testing the Orion heat shield during high-speed Earth re-entry at 25,000 mph
Technical Milestones
The SLS rockets core stage and twin solid rocket boosters generated 8.8 million pounds of thrust at liftoff, making it the most powerful rocket ever to carry humans. Several technical improvements were made following the Artemis I mission:
- Upgraded Orion heat shield with redesigned ablation material
- Improved life support CO2 scrubbing system
- Enhanced communication relay system for far-side lunar operations
- New radiation monitoring equipment for deep space environment assessment
Path to Artemis III
Artemis II is a critical precursor to Artemis III, the mission that will return humans to the lunar surface for the first time since 1972. That mission, currently scheduled for late 2027, will use SpaceXs Starship Human Landing System to transport two crew members from lunar orbit to the surface near the Moons south pole.
NASA Administrator Bill Nelson emphasized that Artemis IIs success is essential for validating the systems and procedures needed for lunar surface operations. Data gathered during this mission will directly inform mission planning for Artemis III and subsequent missions.
Public Enthusiasm
The launch drew an estimated 250,000 spectators to the Space Coast area, the largest crowd for a NASA launch since the Space Shuttle era. Television viewership peaked at approximately 28 million viewers across multiple networks, reflecting strong public interest in the return to the Moon.
The crew is expected to reach the Moons vicinity on April 9 and return to Earth with a Pacific Ocean splashdown on April 15. NASA TV will provide continuous coverage of major mission milestones throughout the 10-day journey.
