On Wednesday, April 1, 2026, at 22:35:12 UTC (Thursday, April 2, at 00:35:12 Polish time), a heavy-lift SLS (Space Launch System) Block 1 rocket lifted off from Launch Complex 39B at the Kennedy Space Center in Florida with four astronauts aboard the Lockheed Martin Orion MPCV (Multi-Purpose Crew Vehicle) spacecraft, bearing the proper name CM-003 Integrity, on the 10-day Artemis II mission, whose destination is lunar orbit.

The two-hour launch window opened at 22:24 UTC (00:24 Polish time). During the countdown, an issue arose with the Flight Termination System, but the countdown was not halted and, after diagnostics were carried out, launch clearance was granted.
This was the first crewed flight toward the Moon since December 1972, when Apollo 17, the sixth and final lunar landing mission of the Apollo program, landed on the surface of the Moon.
Liftoff.
The Artemis II mission launched from @NASAKennedy at 6:35pm ET (2235 UTC), propelling four astronauts on a journey around the Moon.

“Today’s launch marks a defining moment for our nation and for all who believe in exploration. Artemis II builds on the vision set by President Donald J. Trump, returning humanity to the Moon for the first time in more than 50 years and opening the next chapter of lunar exploration beyond Apollo. Aboard Orion are four remarkable explorers preparing for the first crewed flight of this rocket and spacecraft, a true test mission that will carry them farther and faster than any humans in a generation,” said NASA Administrator Jared Isaacman. “Artemis II is the start of something bigger than any one mission. It marks our return to the Moon, not just to visit, but to eventually stay on our Moon Base, and lays the foundation for the next giant leaps ahead.” (Ignition: NASA announces new lunar policy)
The successful launch marks the beginning of an approximately 10-day mission for NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, along with Canadian Space Agency (CSA) astronaut Jeremy Hansen. As NASA’s first crewed Artemis mission, one of its objectives is to demonstrate the life-support systems for the first time in flight and to lay the groundwork for a sustained presence on the Moon ahead of future missions to Mars.
After reaching space, at about the 49th minute of flight, the upper stage of the SLS Block 1 rocket released the Orion MPCV spacecraft, placing it into an elliptical Earth orbit. The spacecraft then deployed its four solar arrays, activating its own power supply, while the crew and engineers on Earth immediately began the transition from launch operations to in-flight operations in order to start checking key systems.
It is worth adding that a crucial role for the Orion spacecraft is played by the ESM-2 (European Service Module), supplied by Airbus Defence and Space. It provides propulsion consisting of 33 maneuvering thrusters as well as onboard power.

Next, the spacecraft will be boosted into a high Earth orbit extending about 74,000 km (46,000 miles) above Earth, and, at a safe distance from Orion, the rocket’s upper stage will deploy four CubeSats from Argentina’s Comisión Nacional de Actividades Espaciales, the German Aerospace Center (DLR), the Korea AeroSpace Administration (KASA), and the Saudi Space Agency (SSA) to conduct scientific research and technology demonstrations.
The spacecraft will remain in high Earth orbit throughout today, during which the crew will carry out a manual piloting operation to test Orion’s capabilities. The astronauts, together with the teams at Mission Control at NASA’s Johnson Space Center in Houston, will continue checking the spacecraft’s systems.
If all systems are operating properly, mission controllers will command the ESM-2 module to perform the trans-lunar injection maneuver on Thursday, April 2. This will be an engine burn of about six minutes, sending the spacecraft onto a trajectory in which the crew will fly around the Moon, after which the Moon’s gravity will act like a slingshot, sending them back toward Earth.
During the planned multi-hour flyby of the Moon on Monday, April 6, the astronauts will take photographs and observe the lunar surface as the first humans to view some areas on the far side of the Moon. Although the far side will be only partially illuminated during the flyby, conditions should create shadows stretching across the surface, enhancing the topography and revealing depth, ridges, slopes, and crater rims that are often difficult to detect under full illumination. The crew’s observations and other scientific research on human health during the mission, such as AVATAR, will help form the scientific basis for future missions to the Moon.
After the successful lunar flyby, the astronauts will return to Earth and splash down in the Pacific Ocean.
