📅 Launch Timeline and Windows
The path to launch has been meticulously planned, with NASA teams working around the clock at Kennedy Space Center in Cape Canaveral, Florida. While an exact launch date hasn't been locked in, the space agency has identified specific launch windows when the orbital mechanics align perfectly for the mission.
Current Mission Status (January 2026)
As of January 27, 2026, the massive SLS rocket and Orion spacecraft are positioned on Launch Pad 39B—the same historic pad that launched many Space Shuttle missions. Engineers are preparing for a critical test called the "wet dress rehearsal," currently scheduled for as early as January 31, 2026, at 9:00 PM ET.
The wet dress rehearsal is essentially a full launch simulation where teams will:
- Load the rocket with its super-cold liquid hydrogen and liquid oxygen propellants
- Run through a complete countdown sequence
- Practice launch-day procedures without actually igniting the engines
- Identify and resolve any technical issues before the actual launch attempt
According to NASA Launch Director Charlie Blackwell-Thompson, if the wet dress rehearsal proceeds without significant issues, February launch opportunities remain achievable. However, NASA emphasizes they will "fly when ready," prioritizing mission success and crew safety over arbitrary deadlines.
Official Launch Windows
NASA has released the following launch windows for Artemis II. Each window is two hours long (except where noted), providing flexibility for countdown holds and last-minute troubleshooting:

If preparations extend beyond April, NASA has additional short launch windows available in subsequent months, though those dates haven't been publicly released yet. The space agency maintains flexibility in the schedule to ensure all systems are thoroughly tested and validated before committing to launch.
🛰️ The 10-Day Mission Profile
The Artemis II mission follows a carefully choreographed sequence of events spanning approximately 10 days from launch to splashdown. Here's what the crew will experience during their historic journey:
Launch Day (Day 0): Liftoff and Trans-Lunar Injection
The mission begins with the thunderous ignition of the SLS rocket. Within seconds, 8.8 million pounds of thrust will propel the spacecraft off Launch Pad 39B, accelerating the crew from zero to over 17,000 miles per hour in just eight minutes.
The solid rocket boosters burn for approximately two minutes before separating and falling back to the Atlantic Ocean. The core stage continues burning for about eight minutes total, pushing Orion into Earth orbit. After reaching a stable parking orbit, the Interim Cryogenic Propulsion Stage (ICPS) fires to perform the trans-lunar injection—the critical burn that sends Orion on its path toward the Moon.
Days 1-3: Outbound Coast to the Moon
For several days, the crew travels the approximately 240,000 miles between Earth and the Moon. During this phase, the astronauts will:
- Conduct comprehensive systems checks of all Orion spacecraft systems
- Test communication links with NASA's Deep Space Network ground stations
- Monitor life support systems including oxygen generation, carbon dioxide removal, and temperature control
- Perform navigational updates and trajectory adjustments using Orion's reaction control thrusters
- Document their experience through photos, videos, and mission logs
- Communicate with mission control in Houston and share their experience with the public
Milestone Alert: During the outbound journey, the crew will pass the altitude record currently held by Apollo 13 astronauts, potentially becoming the humans who have traveled farthest from Earth in history.
Day 4-5: Lunar Flyby
The highlight of the mission occurs when Orion reaches the Moon. Unlike Apollo missions that entered lunar orbit, Artemis II will perform a free-return trajectory—essentially using the Moon's gravity as a gravitational slingshot to redirect the spacecraft back toward Earth.
At closest approach, Orion will pass approximately 6,500 miles above the lunar surface. The crew will have unprecedented views of the Moon, including the far side—the hemisphere that's never visible from Earth due to tidal locking. This will be the first time humans have seen the far side of the Moon with their own eyes since Apollo 17 in 1972.
During the lunar flyby, the crew will:
- Capture high-resolution photographs and video of the lunar surface
- Test navigation and optical sensors at lunar distances
- Validate communication system performance when Earth appears as a distant blue marble
- Monitor radiation exposure in the deep space environment beyond Earth's protective magnetic field
- Experience the psychological aspects of being farther from Earth than any humans in over 50 years
Days 6-9: Return Journey to Earth
After whipping around the Moon, Orion begins its journey back to Earth. The spacecraft coasts homeward while the crew continues testing systems and preparing for the mission's most dangerous phase: reentry.
As Earth grows larger in Orion's windows, the crew will conduct final systems checks, stow equipment, and prepare the spacecraft for splashdown. Mission control continuously monitors the trajectory, making small adjustments as needed to target the precise landing zone in the Pacific Ocean.
Day 10: Reentry and Splashdown
The mission culminates with one of the most challenging maneuvers in spaceflight: atmospheric reentry. Orion will slam into Earth's atmosphere at approximately 25,000 miles per hour—about 32 times the speed of sound. The spacecraft's heat shield, the largest ever built, will experience temperatures reaching 5,000°F as atmospheric friction slows the capsule.
Orion performs a unique "skip entry" technique, bouncing off the upper atmosphere before diving back in, which helps reduce g-forces on the crew and improves landing accuracy. A series of parachutes deploy to further slow the descent, culminating in a splashdown in the Pacific Ocean.
NASA recovery teams, already positioned nearby on naval vessels, will secure the spacecraft and extract the crew within hours of splashdown, bringing the historic mission to a successful conclusion.
Safety First: Orion is designed with multiple redundant systems for every critical function. If any system fails, backup systems automatically engage to ensure crew safety throughout the mission.
