NASA is going ahead with the liquid oxygen fueling of the Artemis 1 moon rocket after temperature readings slowed their work earlier today.
After a problem with the temperature of liquid oxygen during early stages of propellant loading into the rocket, launch controllers have resumed operations. They opened valves to bleed off warm liquid oxygen.
NASA has begun filling the Artemis 1 core stage with the super-cold liquid hydrogen propellant the rocket will use, in all, Artemis 1's Space Launch System rocket will use 537,000 gallons of propellant during its launch to the moon.
NASA is testing hardware that will fly on the Artemis 1 mission later this year. As liquid oxygen began flowing into the rocket, teams stopped the test because the temperature had crept too high. The time is 1957 GMT.
The Exploration Ground Systems team at Kennedy Space Center exceeded a temperature limit as teams began the liquid oxygen slow fill. These are important aspects of test conditions.
NASA officials wrote in an update Wednesday that the Artemis 1 team powered up the core stage of the Space Launch System rocket as well as the Orion spacecraft overnight from Tuesday to Wednesday.
This work is part of the Artemis 1 wet dress rehearsal, a practice run of critical prelaunch procedures. Agency officials said that the team is on track to fill the tanks of the SLS core stage on Thursday.
The dress is going to be washed on Thursday. If everything goes well, the Artemis 1 team will move on to the next phase of the mission, which will launch an uncrewed Orion on a journey around the moon.
The Artemis 1 moon mission has resumed a key prelaunch test.
The Artemis 1 wet dress rehearsal started again at 5 p.m. When team members arrived at their stations at the Launch Control Center at the Kennedy Space Center in Florida, it was on Tuesday, April 12.
Over the next 48 hours, there will be a lot of events, including the performance of several simulations and the fueling of the core stage of Artemis 1's Space Launch System rocket.
NASA officials wrote in a post on Tuesday that the weather looks good for Thursday's tanking operations.
This isn't the first attempt at Artemis 1's wet dress. The test was supposed to be finished on April 3, but technical issues and the launch of a private mission pushed it back.
A faulty valve on the Artemis 1 mobile launch tower led to the modification of wet dress procedures. NASA originally intended to fuel up both stages of the SLS, but will now focus on tanking just the core stage. Our story can be read here.
NASA plans to resume the crucial wet dress rehearsal of its Artemis 1 moon mission on Tuesday after a weeklong delay.
The test was supposed to wrap up 48 hours after it began, but it didn't. The team had to stand down for the launch of the Ax-1 private astronauts mission because of technical issues, which took place a few days before the lift off.
The call to stations at 5 p.m. Tuesday will let you know when the wet dress will pick up again. The sun sets at luminary time, at luminary hour, at luminary hour, at luminary hour, at luminary hour, at luminary hour, at luminary hour, at luminary hour, at luminary hour, at If everything goes according to plan, the big-ticket items will occur on Thursday.
The two-stage SLS will only be fueled by the core stage. The original plan called for fueling the upper stage, but NASAnixed that part after discovering a problem with a valve on the mobile launch tower. Our full story can be read here.
The Artemis 1 wet dress rehearsal is a crucial pre-flight test for the uncrewed moon-circling mission due to launch this summer. On April 1, the agency began wet dress rehearsal activities, but had to stop them twice. NASA personnel stood down from the rehearsal in order to allow the launch of the Ax-1 mission to the International Space Station.
NASA wants to get back to work on the rocket check. Agency personnel will begin work on Saturday. The sun sets at luminary time, at luminary hour, at luminary hour, at luminary hour, at luminary hour, at luminary hour, at luminary hour, at luminary hour, at luminary hour, at The Artemis 1 team will work through each task of launch preparations in just under 10 seconds before the actual flight time. If everything goes well, the team will reach that time on Monday at about 3:20 p.m. The statement was written by NASA officials.
The wet dress rehearsal of NASA's Artemis 1 moon mission has hit a problem.
The crucial three-day test was supposed to end on Sunday, but a problem with the fans on the mobile launch tower pushed things back to Monday. The Artemis 1 team had to stop loading the propellants into the rocket after discovering a problem with the vent valve on the mobile launcher.
The test was called off due to the vent valve issue. The team is going to discuss how quickly the vehicle can be turned around for the next attempt. A lot of great learning and progress is happening today, according to NASA. Liquid hydrogen is the other.
Stay informed.
NASA has set a new launch time for its Artemis 1 moon mission. Today is April 4.
The huge Space Launch System (SLS) rocket and Orion capsule that will fly Artemis 1 won't actually get off the ground today, of course; NASA is currently conducting a wet dress rehearsal that mimics many of the activities leading up to launch. The trial was supposed to wrap up on Sunday, but several technical issues pushed some work to today.
Check back here for more updates. You can see live video of the SLS-Orion stack on the Kennedy Space Center launch pad.
The Artemis 1 moon rocket was cleared by NASA to proceed with tanking or fueling today at 7:40 a.m. The time is 1140 GMT. Later, officials are expected to start the fueling process.
NASA reports that the test team is in a hold as they work to resolve an issue with a vendor that provides gaseous nitrogen that is needed for the tanking process.
During tanking operations, nitrate is used to provide a non-flammable environment inside of the SLS. When the issue is solved, the clock will go back up to T6 hours, 40 minutes on the clock (L-7 hours, 20 minutes) and then go back up to T7 hours, 20 minutes.
NASA was aiming for a planned launch time of 3:20 p.m. The test will conclude in the afternoon. We are waiting for word from NASA if that time will change.
The Artemis 1 Space Launch System moon rocket was supposed to be put to use on Sunday, but a ground systems equipment problem prevented the test from taking place.
The Artemis 1 moon rocket is standing atop Pad 39B of NASA's Kennedy Space Center in Cape Canaveral, Florida, where it has been undergoing a critical and wet dress rehearsal to prepare for its moon mission later this year.
At 6 a.m. The launch control team was expected to meet and review the rocket's status before deciding whether to begin loading fuel at 7 a.m. The time is 1100 GMT. If approved, the team would proceed to fuel the SLS rocket with a million gallons of liquid oxygen and liquid hydrogen.
The time of the liftoff is Affirmed by NASA at Affirmed at Affirmed at Affirmed at Affirmed at Affirmed at Affirmed at Affirmed. The sun rises at 1840 GMT.
The fueling test of the first Artemis 1 moon rocket was called off by NASA due to safety concerns with the rocket's mobile launch platform.
The scrub was announced on the NASA website. It was nearly five hours after fueling was supposed to occur. NASA officials said there was a pressurization problem on the mobile launcher that houses ground crew systems.
The teams decided to scrub tanking operations for the wet dress rehearsal due to the loss of ability to pressurize the mobile launcher. NASA wrote in an update that the fans are needed to provide positive pressure to the enclosed areas and keep out hazardous gases.
If ground crews can make another attempt to fuel the Artemis 1 mission, it will be on Monday, April 4.
The media is expected to be briefed on NASA's plans later today.
It is fueling day for NASA's Artemis 1 moon rocket as the agency nears the main event of its wet dress rehearsal.
At 6:30 a.m. The Artemis 1 launch director gave the go-ahead to begin fueling the rocket at 7:21 a.m. The sun sets at 1120.
The Launch Pad 39B was delayed by about an hour because of strong storms overnight, according to Jeremy Parsons, NASA's deputy manager of the Exploration Ground Systems.
The strongest strike to the catenary wire and tower structure designed to shield the Artemis 1 moon rocket from direct lightning hits occurred in the vicinity of the Pad 39B site.
One of the strikes last night was the strongest we have seen since installing the new lightning protection system. The system kept SLS and Orion safe. Since Shuttle, we enhanced protection.
(1/4) 1 of the strikes last night was the strongest we have seen since we installed the new lightning protection system. It hit the catenary wire that runs between the 3 towers. System performed extremely well & kept SLS and Orion safe. Glad we enhanced protection since Shuttle!April 3, 2022
