Good morning, Space Fans!
Today is Saturday, Jan. 31 and tonight NASA is gearing up to to begin its first fueling test for the the Artemis 2 Space Launch System moon rocket for a so-called “wet dress rehearsal.” That’s NASA-speak for let’s gas up the rocket and see if it is working right.
While the fueling test is actually scheduled for Monday, Feb. 2, the work actually begins tonight at about 8 p.m. ET (0100 Feb. 1 GMT). That’s because launch flight controllers and pad engineers need to begin taking their stations 49 hours BEFORE the fueling test’s planned T-0 “launch” time of 9 p.m. ET on Monday.
The Artemis 2 fueling test is being conducted at Launch Pad 39A of NASA’s Kennedy Space Center in Florida, where the towering 322-foot rocket was rolled out earlier this month.
The fueling test has seesawed a bit back and forth. It was originally scheduled for Feb. 2, then moved up to Jan. 31, then pushed back to Feb. 2 due to freezing temperatures at the Kennedy Space Center this weekend.
The Artemis 2 launch date will depend on the results of this fueling test. Currently, Artemis 2 is scheduled to launch 4 astronauts to the moon no earlier than Feb. 8.

Artemis 2 moon launch may delay ISS Crew-12 mission
NASA’s plan to launch its Artemis 2 astronauts around the moon around Feb. 8 has cast doubt on whether the next U.S. crew launch to the International Space Station will lift off on time.
Artemis 2 is currently scheduled to launch four astronauts around the moon late in the evening on Feb. 8 from Launch Pad 39B at the Kennedy Space Center in Florida. NASA’s Crew-12 mission to the ISS was scheduled to launch on a SpaceX Dragon capsule and Falcon 9 rocket from a nearby pad at the Cape Canaveral Space Force Station.
But if Artemis 2 launches on time, or anytime during its launch window of Feb. 8 to Feb. 11, NASA will wait to launch Crew-12 to the International Space Station until at leas Feb. 19, after the Artemis 2 astronauts return home from their 10-day mission, NASA officials said in a press conference today.

NASA delays Artemis 2 fueling test back to Feb. 2
Happy Friday, Space Fans! It is Jan. 30 and this morning, NASA pushed back its planned “wet dress rehearsal” test of the Artemis 2 moon rocket to no earlier than Feb. 2 (it’s original date) due to freezing temperatures at its Launch Pad 39B pad at the Kennedy Space Center in Florida.
Here’s our latest update from writer Josh Dinner:
Notice anything about that headline? If you said the launch date, you get a prize.
With the wet dress rehearsal, essentially a critical fueling test of the Artemis 2 Space Launch System moon rocket, now back on Feb. 2, NASA said in a statement that it can no longer target Feb. 6 or Feb. 7, the first two days of its launch window. The Artemis 2 launch window originally ran from Feb. 6 to Feb. 10.
NASA does have opportunities to launch the mission on Feb. 8, Feb. 10 and Feb. 11. A Feb. 8 launch would lift off at 11:20 p.m. ET (0429 GMT), NASA has said.

NASA beginning wet dress rehearsal operations Thursday evening
Artemis 2 mission operators at NASA are preparing the Space Launch System (SLS) rocket for it’s last critical test before launch.
The SLS wet dress rehearsal will simulate a mission countdown for ground teams to power on and fuel the rocket as a final qualifying check before Artemis 2 launches to the moon.
NASA is targeting a call to stations as early as 8:00 p.m. EST (2000 GMT) on Thursday (Jan. 29), about 49 hours before a simulated liftoff time on Saturday, at 9:00 p.m. EST (0200 GMT, Feb. 1).
If the test goes smoothly, NASA could choose to proceed toward the February launch window for Artemis 2, which opens Feb. 6-10.

What are the key steps in the Artemis 2 SLS wet dress rehearsal?
Artemis 2 SLS Wet Dress Rehearsal: Latest Updates on Moon Rocket Fueling Tests
The Space Launch System (SLS) for the artemis 2 mission is gearing up for a crucial wet dress rehearsal,a critical step in preparing for the first crewed lunar mission in over 50 years. This comprehensive test simulates the entire fueling process, from propellant loading to final countdown sequences, without actually launching the rocket. Here’s a breakdown of the latest news and what it means for the future of lunar exploration.
What is a Wet Dress Rehearsal and Why is it Important?
A wet dress rehearsal isn’t just about filling the SLS with liquid hydrogen and liquid oxygen; it’s a full systems integration check. It validates:
* Propellant Loading Procedures: Ensuring the safe and efficient loading of cryogenic propellants.
* Countdown Sequence: Verifying the automated and manual procedures leading up to launch.
* Systems Integration: Confirming all SLS components, the Orion spacecraft, and ground support equipment work seamlessly together.
* Emergency Procedures: Testing responses to potential anomalies during fueling and countdown.
Successfully completing this rehearsal is paramount. It identifies potential issues before astronauts are onboard, minimizing risk and maximizing the chances of a successful Artemis 2 launch. Any problems discovered now allow engineers time to troubleshoot and implement solutions without delaying the mission substantially.
Artemis II Mission Objectives & The Role of Orion
The Artemis II mission itself is a pivotal moment. It will send four astronauts – Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen – on a lunar flyby, testing the Orion spacecraft’s life support systems and capabilities in deep space.
According to NASA, one of the first objectives for the Artemis II crew will be to manually pilot their Orion capsule, named Integrity. This demonstrates a crucial capability for future missions, allowing astronauts to take control if necessary.The SLS rocket is specifically designed to deliver Orion beyond Earth orbit,setting the stage for this critical test.
Current Status of the Wet Dress Rehearsal
As of January 31, 2026, NASA is preparing to take stations for the upcoming SLS fueling test. This involves:
* Final System Checks: Engineers are meticulously inspecting all SLS hardware, including the core stage, boosters, and Orion interface.
* Propellant supply Readiness: Ensuring sufficient quantities of liquid hydrogen and liquid oxygen are available and chilled to the required cryogenic temperatures.
* Range Safety Coordination: Collaborating with the U.S. Space Force to establish a safe launch zone and monitor the test.
* Weather Monitoring: Closely tracking weather conditions, as lightning or strong winds can pose a risk during cryogenic operations.
the exact timing of the wet dress rehearsal is dependent on these factors, but NASA is aiming to complete it within the next few weeks.
Lessons Learned from Previous Wet Dress Rehearsals
The Artemis 1 mission, an uncrewed test flight, also underwent multiple wet dress rehearsals. These earlier tests revealed valuable insights:
* Valve Issues: Initial rehearsals encountered challenges with valves responsible for controlling propellant flow. These were addressed through hardware modifications and software updates.
* Hydrogen Leakage: Minor hydrogen leaks were detected, prompting improvements to sealing mechanisms.
* Countdown Synchronization: Refining the synchronization between ground control systems and the SLS flight computer.
These lessons have been directly incorporated into the preparations for the Artemis 2 wet dress rehearsal, increasing confidence in the system’s reliability.
Benefits of the artemis Program & Lunar Exploration
The Artemis program isn’t just about returning to the Moon; it’s about establishing a lasting presence and using the Moon as a stepping stone for future missions to Mars. Key benefits include:
* Scientific Discovery: unlocking new insights into the Moon’s formation, history, and potential resources.
* Technological Advancement: Driving innovation in areas like robotics, life support systems, and propulsion.
* Economic Growth: Creating new opportunities in the space industry and related fields.
* International Collaboration: Fostering partnerships with space agencies around the world.
What to Expect After the Wet Dress Rehearsal
Following the successful completion of the wet dress rehearsal, the SLS will be rolled back to the Vehicle Assembly Building (VAB) for final checkouts and integration with the orion spacecraft. The launch date for Artemis 2 is currently targeted for late 2026, but this is subject to change based on the results of the wet dress rehearsal and any unforeseen issues.
