Non-essential personnel cleared from launchpad ahead of SLS fueling
With the sun rising on the second day of the Artemis 2 wet dress rehearsal, NASA is preparing the SLS for the test’s most critical phase: Fueling.
Following NASA’s countdown timeline, all non-essential personnel were scheduled to be cleared from Launch Complex-39B this morning (Feb. 2), ahead of operations to begin fueling SLS with cryogenic propellants.
The fueling portion of the wet dress rehearsal will begin around 11 a.m. EST (1600 GMT), and encompass the remaining 10 hours of testing. NASA is targeting a simulated T-0 of 9 p.m. EST (0200 GMT, Feb. 3), which they say could extend to early Tuesday morning (Feb. 3) at 1 a.m. EST (0600 GMT).

Artemis 2 moon rocket powered up for test
NASA engineers have powered up the huge core stage of the Artemis 2 Space Launch System rocket that will take four astronuts to the moon later this month, but only if the mega booster passes a critical fueling test on Monday, Feb. 2 at its Pad 39B launch pad at the Kennedy Space Center in Florida.
NASA began the 49-hour countdown toward the fueling test (which reaches a simulated launch time at 9 p.m. EST on Monday) on Saturday night, with the clock started at 8:13 p.m. EST (2313 GMT). If all goes well, the Artemis 2 mission could launch astronauts to the moon as early as Feb. 8.
Overnight, NASA powered up the second stage of the rocket and earlier today the massive core stage of the 322-foot Space Launch System booster was powered on, NASA said.
“Early this morning, at approximately L-39 hours and 30 minutes, teams powered up the rocket’s core stage, which soon will be loaded with more than 700,000 gallons of liquid oxygen and liquid hydrogen during the tanking phase of the countdown. This will occur over a series of different propellant loading milestones to fill, top off, and replenish the tanks. The interim cryogenic propulsion stage was powered up overnight,” NASA wrote in an update.
“Orion has remained powered over the last several days due to cold temperatures in Florida. Engineers are preparing to charge Orion’s flight batteries and soon will begin core stage battery charge,” the agency said.

Countdown begins for Artemis 2 fueling test
Good morning, space fans! Happy Sunday.
NASA officially began the countdown last night for its upcomiong Artemis 2 fueling test as it works toward a Feb. 8 launch target for the first astronaut trip around the moon in over 50 years.
The countdown began at 8:13 p.m. EST (2313 GMT), which marked the L-48 hours, 40-minute mark to a “simulated” launch time on Monday, Feb. 2 at 9 p.m. EST (0200 Feb. 3). The so-called wet dress rehearsal will run through about 1 a.m. EST (0600 GMT) on Feb. 3, NASA has said.

“This test will run the launch team, as well as supporting teams in the Mission Control Center at NASA’s Johnson Space Center in Houston and other supporting NASA centers, through a full range of operations, including loading cryogenic liquid propellant into the SLS (Space Launch System) rocket’s tanks, conducting a launch countdown, demonstrating the ability to recycle the countdown clock, and draining the tanks to practice scrub procedures,” NASA wrote in an update. “These steps ensure the team is fully prepared for launch day.”
The Artemis 2 mission will last about 10 days and send four astronauts around the moon on an Orion spacecraft atop NASA’s giant Space Launch System megarocket. The launch window this month runs from Feb. 8 to Feb. 11, with additional windows in March and April.

Artemis 2 fueling test to begin preps tonight
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:
NASA delays critical Artemis 2 rocket fueling test due to below-freezing temperatures, launch no earlier than Feb. 8
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.
