NASA recalibrating new T-0 for Artemis 1 moist gown rehearsal

NASA is recalibrating the T-0 for its Artemis 1 moist gown rehearsal after failing in an try to repair a hydrogen leak in a “quick disconnect” line within the Space Launch System rocket’s core stage, company officers mentioned in an replace this afternoon (June 20).

Technicians tried warming up after which cooling down the fast disconnect, hoping that will reseat the {hardware} and seal the leak. But it did not work, so Artemis 1 staff members are “putting their heads together and seeing if they can come up with any other options to seal that leak,” NASA spokesperson Derrol Nail mentioned this afternoon in the course of the company’s webcast of the moist gown rehearsal. 

Nail added that the staff can be attempting to provide you with a brand new T-0 , the milestone that may wrap up the moist gown rehearsal. The present T-0 is 4:38 p.m. EDT (2038 GMT), nevertheless it’s been obvious for a while now that Artemis 1 wouldn’t hit that mark.

Three of 4 SLS propellant tanks now crammed

Three of the 4 propellant tanks on the Artemis 1 Space Launch System rocket are actually crammed, and the fourth may very well be tanked up quickly, NASA officers in a Twitter update this afternoon (opens in new tab) (June 20). 

“Liquid oxygen is currently at fast fill for upper stage. Team is working a plan to reseal at the hydrogen leak,” the tweet reads, partially. That leak was noticed earlier at present at a “quick disconnect” on the SLS core stage.

2022-06-20T19:21:07.902Z

Teams at NASA’s Kennedy Space Center in Florida proceed troubleshooting the hydrogen leak on the core stage fast disconnect of the Space Launch System rocket, which stopped the fueling operation of the Artemis 1 moist gown rehearsal check earlier at present. 

Teams from Boeing in addition to NASA are on website attempting to seal the leak, hoping to have the ability to proceed with the check, though it is unlikely that T-0 will happen at 4:38 p.m. EDT (2038 GMT) as nonetheless formally deliberate. 

“Team is working to manually adjust the LOX pressure in upper stage to get back into tanking,” NASA said on Twitter (opens in new tab).

The fueling of the rocket’s higher stage has been accomplished.

Hydrogen leak troubleshooting ongoing throughout Artemis 1 tanking

Artemis 1 groups are at the moment troubleshooting the leak on the core stage fast disconnect. 

“This includes manually configuring valves to reduce the pressure on the upper stage,” spokesperson Derrol Nail mentioned on NASA Television. 

Whilst troubleshooting continues, there isn’t a plan to intervene with the small grass fireplace that’s burning close to the hydrogen flare stack, in keeping with Nail. 

As the grass is burning in the direction of a mud highway the idea by the launch staff is that it’s going to burn out as soon as it will get to the highway. 

“It would be more risky to send a team out there to put it out,” Nail mentioned.  

It continues to be unclear what impacts these points would have, if any, on the deliberate T-0 in the course of the moist gown rehearsal, at the moment set for 4:38 p.m. EDT (2038 GMT).

2022-06-20T18:14:36.750Z

Hydrogen leak, grass fireplace found throughout Artemis 1 tanking

NASA says Artemis 1 groups are “working on an issue with the liquid hydrogen” throughout tanking operations of the core stage, amongst different points.

“They are getting some data that says there’s a leak, a liquid hydrogen leak, in the quick disconnect that takes the bleed for the engines,” spokesperson Derrol Nail mentioned on NASA Television round 2:07 p.m. EDT (1807 GMT).

“The team is currently evaluating that situation,” Nail mentioned. “Of course, any leak of liquid hydrogen is something … to be concerned about for the launch team. This is a hazardous gas. They want to understand the situation fully before they take any action.”

Nail added there are extra points forthcoming: there seems to have been a strain restrict exceeded throughout fueling within the liquid oxygen for the higher stage, and a small grass fireplace has emerged close by the launch pad. 

It is unclear what the grass fireplace was brought on by, and company officers have their cameras on the realm to observe the smoke popping out of the grass.  

It is unclear what impacts these points would have, if any, to the deliberate T-0 in the course of the moist gown rehearsal, at the moment set for 4:38 p.m. EDT (2038 GMT).

Core stage nearly accomplished on tanking; higher stage ‘a little bit behind’

The core stage of the Space Launch System is sort of accomplished tanking. Liquid hydrogen is totally tanked, whereas liquid oxygen is at 90%, NASA spokesperson Derrol Nail mentioned throughout a Monday (June 20) replace at 1 p.m. EDT (1700 GMT) on NASA Television.

The higher stage entered chilldown of its fuel strains at 1:03 p.m. EDT (1703 GMT) to arrange it for entry of the cryogenic fuel, Nail added.

“We’re running a little behind on the tanking for the upper stage, probably about a half hour or so,” Nail added. “Tweaking of an upper stage skid took a little longer than expected.”

So far, the T-0 within the moist gown rehearsal countdown stays at 4:38 p.m. EDT (2038 GMT) following now-resolved delays from early within the morning EDT. Preparations for the check have been working for almost two days since a name to stations at 5 p.m. EDT (2100 GMT) on Saturday (June 18).

Liquid hydrogen enters ‘quick fill’

Liquid hydrogen tanking is now getting into a ‘quick fill’ part as engineering groups work to get the Space Launch System megarocket tanked for the moist gown rehearsal of Artemis 1 later at present, NASA officers mentioned in an replace round 11:30 a.m. EDT (1530 GMT).

Liquid oxygen and liquid hydrogen are being tanked on the similar time, however the flows on every fuel are being adjusted. Hydrogen is flowing a bit sooner and oxygen is flowing a bit slower, defined spokesperson Derrol Nail within the replace on NASA Television.

The purpose is to keep away from an “aft strut constraint”, Nail mentioned. Aft struts are horizontal attachment factors between the strong rocket boosters on both facet of the core stage of SLS.

“The vehicle moves during fueling. It’s very much alive. As the super-chilled propellants go into that tank, it [the vehicle] becomes heavier,” Nail mentioned. 

The steel on the tanks additionally shrinks barely as a result of cryogenic temperatures of the hydrogen and oxygen, he added. “For that reason, the propellants are put in in proportion to each other.”

The liquid hydrogen tank, at 537,000 gallons (2.4 million liters), is predicted to complete earlier than the liquid oxygen tank at 196,000 gallons (roughly 740,000 liters), Nail mentioned. Liquid hydrogen is way much less dense than liquid oxygen. 

The oxygen tank is roughly 38% crammed as of the replace time, whereas the hydrogen tank stands at lower than 5%; the oxygen tank will not be allowed to exceed 49% crammed till the hydrogen tank will get to at the least 5%, in keeping with NASA.

2022-06-20T15:21:18.794Z

Artemis 1 groups modify liquid oxygen and hydrogen stream

Liquid hydrogen is now flowing in the course of the Artemis 1 moist gown rehearsal, NASA officers mentioned round 11:10 a.m. EDT (1500 GMT) on Monday (June 20), confirming that announcement in an company tweet (opens in new tab).

As liquid hydrogen tanking proceeds within the Space Launch System megarocket, the hydrogen’s stream price will probably be barely accelerated in gentle of liquid oxygen tanking operations, which have been ongoing for about an hour.

The liquid hydrogen staff anticipates they are going to barely speed up their stream of fuel, whereas the liquid oxygen staff plans to decelerate their price, NASA spokesperson Derrol Nail mentioned throughout a NASA Television replace.

That’s as a result of liquid hydrogen should be crammed as much as at the least 5% within the SLS tank earlier than liquid oxygen loading is permitted past 49% ranges, Nail mentioned. (Current ranges are at 15% for liquid oxygen, he famous, so slowing down the oxygen stream is a precaution.)

Teams seem like fastidiously adjusting these oxygen-hydrogen flows to cut back hundreds on the SLS throughout tanking, though NASA Television didn’t immediately affirm that. The process is named an “aft strut constraint.” The SLS has 4 struts securing the core stage to the boosters when the megarocket is stacked on the cell launcher, in keeping with NASA documentation (opens in new tab).

Artemis 1 begins sluggish fill of hydrogen

NASA has given the go for Artemis 1 to start “slow fill” of liquid hydrogen in preparation for the moist gown rehearsal, the company mentioned on NASA Television Monday (June 20) round 10:42 a.m. EDT (1442 GMT).

Liquid hydrogen will then be licensed for a “fast fill”, offering that tanking operations proceed as deliberate. The milestone was confirmed on the company’s Exploration Ground Systems Twitter account in a brief tweet (opens in new tab).

“The reason for that [slow fill] is to properly condition the vehicle,” spokesperson Derrol Nail mentioned on NASA Television. “The engineers are trying to prevent thermal shock to the system by flowing too much super-chilled propellant too fast.”

NASA provides ‘go’ for liquid hydrogen tank filling

Engineers have a “go” to proceed for liquid hydrogen tank filling, NASA Television mentioned in an replace Monday (June 20) round 10:30 a.m. EDT (1430 GMT). 

The milestone was confirmed on the company’s Exploration Ground Systems Twitter account (opens in new tab) at 10:33 a.m. EDT (1433 GMT).

“This is a major milestone,” spokesperson Derrol Nail mentioned on NASA TV. “As you may recall from previous wet dress rehearsals, there was a leak …the umbilical leak was fixed, so this is a big moment for the team.”

NASA had made a number of makes an attempt to carry out the moist gown rehearsal in April, however finally pulled the Space Launch System and Orion spacecraft stack again to NASA’s Kennedy Space Center’s Vehicle Assembly Building to deal with the hydrogen leak situation.

Tanking operations are ongoing. Liquid oxygen entered a “fast fill” part earlier within the hour, and liquid hydrogen strains are actually being pre-chilled in preparation for tanking.

The cryogenic cooling was anticipated to start at 9:05 a.m. EDT (1305 GMT) as NASA officers proceed with the check, which is a key milestone in assessing the Space Launch System megarocket and Orion spacecraft for his or her readiness to carry out a round-the-moon mission.

Jeremy Graeber, assistant launch director, instructed listeners on NASA Television that the gaseous nitrogen situation holding up tanking operations earlier within the morning EDT has been resolved. Both the gaseous nitrogen valve and the controller, which had been troublesome, are actually working correctly following beforehand disclosed engineering fixes.

“The team did a great job identifying the problem and resolving it, and so we’re in really good shape,” Graeber mentioned. “That problem has been cleared and we’re at a good configuration to pick up with cryo loading [and] no longer constrained.”

Engineers have additionally picked up a problem with the left strong rocket booster, exhibiting that the resistance was decrease than anticipated, Graeber mentioned. But given the constant historical past of the booster’s efficiency, the groups determined to proceed and to not declare it a constraint to the moist gown rehearsal.

The resistance check was exhibiting a price of twenty-two.4, in comparison with a nominal studying of between 24.4 and 37.4, Graeber mentioned. 

“The value we’re seeing now is consistent with what we’ve been seeing over the last several weeks,” he added. “So although it is outside of our nominal range, we understand that it’s consistently here. So we believe that’s a valid number.”

Weather is predicted to stay good for tanking operations regardless of T-0 (the simulated liftoff) being pushed again about two hours to 4:30 p.m. EDT (2030 GMT), Graeber added.

“It would not close,” NASA’s Derrol Nail, a communications consultant, mentioned throughout a broadcast on NASA Television. “Not sure about what caused the failure at this time, but the teams have been working on it and have replaced the valve. The manual retest of that valve is working well, according to the team that’s out there.”

Teams are actually centered on an computerized controller for the backup gaseous nitrogen line, performing checks to see if that may work correctly, Nail mentioned. Provided they get the controller working, engineers have additionally determined to maneuver the troublesome gaseous nitrogen as the first supply for the rocket’s check. (There are two sources; it was the redundant one inflicting points, however the prime one was working simply effective.)

“The launch team, meanwhile, has been moving forward configuring the launch vehicle for tanking,” Nail continued. “They have cycled the valves for liquid oxygen tank in the upper stage, and then began proceeding with cycling the valves on the liquid oxygen stage.”

NASA is offering updates roughly each half hour on its live broadcast (opens in new tab) as tanking operations proceed for the moist gown rehearsal, which can happen later at present (Monday) if all goes to plan. Exact rescheduled timing for testing procedures haven’t been launched but, because the troubleshooting is ongoing; the nominal plan had put the primary anticipated terminal countdown at 2:30 p.m. EDT (1830 GMT).
