Mcginnis and today you will hear an update from nasa leadership following the scrub of the artemis one launch this morning after the team encountered an issue heading one of the four engines to the proper temperature for lift off. Earlier in the countdown, the teams were able to troubleshoot another issue. And the rocket remained in a safe configuration as teams assess the next step. Here to talk about todays operations and the path forward are our nasa administrator, the Artemis Mission manager and the associate administrator for the Systems Development mission directorate, jim pre jim. We will also hold a teleconference tomorrow to keep you updated. We will take questions from those of you in the room and on the phone and if you are joining us on the phone, please press star one to join the queue. I am very proud of this launch team. They have solved several problems along the way and they got to one that needed time to be solved. I am very grateful to you all for your patience. This is a brandnew rocket. It is not going to fly until it is ready. There are millions of s of this rocket and its systems, and needless to say, the complexity is daunting when you bring it all into the focus of a countdown. You all, no doubt, have been up for some period of time. Our remarks will be short and then we will open up for your questions. I want to say, the Vice President was here. She was pumped the entire time. She is very bullish on our Space Program and on this particular program of going back to the moon and going to mars. We had her meet with assembled guests. We had her meet with members of congress who were here. She toured the omc building, saw the artemis hardware there for the future. Overall, she had a very productive visit, and i would expect that you will see her at a future launch. I want to say, understand that scrubs are just a part of this program. The space flight that i participated in, the commander, 36. 5 years ago, we scrubbed four times on the pad. It was the better part of a month. Looking back, had we got off to a Perfect Mission after the fifth try, it would not have been a good day if we launched on any one of those four scrubs. When you are dealing with a high risk business and spaceflight is risky that is what you do. You buy down that risk, you make it as safe as possible, and of course, that is the whole reason for this test flight, to test it, stress it, make sure it is as safe as possible when artemis 2, when we put humans into the spacecraft. For the details, let me turn it over to mike serafin. Mike good afternoon. It has been a very dynamic 48 hours since i was last here to talk to you. The technical issues the team has worked through, they have overcome a number of them but we ran into one that we need more time to look at. But the american spaceport has been dynamic. We launched a space control center, new spacecraft, and we watched a new rocket come to life. We watched the media show up, thousands of videos theres visitors show up. It has been a dynamic 48 hours. Since we had our launch minus two day Mission Management meeting, a lot control center entered their launch countdown saturday morning. Saturday afternoon, we had a couple of lightning strikes on the pad. We have a 32story rocket out there and there were lightning strikes on towers one and two. Our technical teams quickly resolved and there were no issues with the vehicle through timely analysis and timely data assessment. Saturday afternoon, we also closed out an action from the launch minus two day Mission Management which was to rear verify our communications covered associated with some weight changes that we had with the rocket and spacecraft. The team got comfortable with the communications plan. Sunday was largely a day of rest, data preparation for the team. Sunday evening, a subset of the team came in for the tanking meeting. Myself, charlie blackwellthompson, other elements came in at 10 50 the prior evening, reassessed the readiness to load the vehicle with cryogenic oxygen, cryogenic fuel. We were a go for that. We had a go Weather Forecast was 20 chance of lightning, 40 chance of precipitation through the cryo loading period. During that time the team encountered an issue with the verification on the Orion Software. It had about 20 minutes for a man to verify the flight software. It was a simple misconfiguration. One of the command and control modules was not activated. The team quickly resolved that. Once they configured it, they quickly worked through the software verification. There were no concerns at that point with the Orion Software verification. The tanking meeting itself was very clean. We were done in 30 minutes, gave the go for tanking. Shortly after, the Kennedy Space center went into a lightning alert. Tanking was delayed for about one hour. Once the cyro loading started, we started loading of the hydrogen. The team quickly encountered a Hydrogen Leak at the eightinch Quick Disconnect, our fill in drain. That happened when they went into the fast fill stage. They had to slow down the loading operation, chill down the interface, managed to work their way through the full cyro loading operation of the core stage and upper stage successfully. Once we got through the propellant loading on the rocket, both the core stage in the upper stage, they started the engine bleed. We talked and our flight readiness review about the engine bleed, we knew that was a risk cutting into this launch campaign, the first time demonstrating that successfully. We did encounter an issue chilling down into number three. We needed the engine to be at the cryogenically cooled to temperatures such that when it starts it is not shocked with all of the cold fuel that flows through it, so we needed extra time to assess that. When the team started working on that, they also sign issue with a vent valve at the inner tank. The combination of not being able to get engine to reach chill down, the vent valve issue that they saw on the inner tank caused us tos today and we felt like we needed a little more time. There was also a series of weather issues throughout the window. We have been nogo early in the window due to precipitation, and then later ,nogo because of lightning within the launchpad area. The team worked through a number of issues today. The team was tired at the end of the day. We decided it would be best to knock it off and reconvene tomorrow. We have a Mission Management team meeting tomorrow at 3 00 eastern. We will give the time to rest and then come back fresh tomorrow and reassess what we learned today, then develop a series of options. It is too early to say what the options are. As jackie said earlier, we will come back and talk about where we stand tomorrow evening with all of you. Again, it is an incredibly hard business that we have. In spite of the challenges that we have as well as some other constraints the team had to work through, set up for. For example, we had 42 collision cutouts that we had to manage over the course of the twohour window. Most of those are couple seconds long, some about a minute long. When you think about the type of mission we are flying, it helps you understand how unique and how complex the space launch system is, the orion and the Artemis Program is. We have this upper stage, the propulsion stage that lost the spacecraft to a 900 nautical mile insertion along with the sos core stage. With that we need the performance of it but we also fly through a orbital debris field. One orbit later, we commit to the point of translator check. As we fly down to lower earth orbit, we have to know where all of these objects are. That explains those 42 cutouts. That is something that our Operations Team were paired to do today, we just didnt get to the launch window. A number of challenges. We were ready for some of them. The technical challenges we encountered on the engine bleed, vent valve, those are things that we mean to look at today, tomorrow after we get smarter and get rested. With that, i will pass it over to jim. Jim good afternoon. The administrator and mike covered a lot of things. A few things from me. I sit in a different Vantage Point from mike. His is a lot more fun. We are in the lcc. I found some things in the team today. This was an important attempt for us. We talked about that after what transpired, questions about should we have rolled back, try to do another test . We still feel like going for today was the right thing to do. And that comes in a few ways. Our launch team was really pushed today. They were working a lot of issues, looking at a compressed timeline with that hold at the beginning. We were filling all four tanks at the same time at one point, pushing our team through a timeline. The weather. Mike talked about the weather. Lightning was coming in and out. We were not able to go at the beginning of the window like we thought. There was a lot of coms from the launch weather officer. The hydrogen that mike talked about, when we went to Manual Control, that is something that we did on the locks, when we had issues loading the locks the first time. Going to Manual Control to me is learning. Getting through the first Hydrogen Leak that we had, the same week that we had on the same line to the same level. When we started to do the manual fast fill, honestly, it kept climbing and i thought we would never get out of this, but that got us out of it. To me, what we pushed the team through and i know we can get talking about the team too much. But we continue to learn. That is what we do. Bob said it, we are testing the people and the processes. We put ourselves through a compressed timeline. We will get some shorter launch windows that we have to deal with where these skills will help us. You heard from charlie about extending our timeline about one hour earlier to give us time to work things. I think that helps us today to work things. Frankly, engine three that mike talked about, we didnt get down to the temperature that we wanted. But the other four were not as low as we would like to. There are some things going on. The team needs to look at the data and understand how this is different from what we did during the green run. Then figure out a path forward, which is where we ultimately want to go. We will not have all the data and the implications today. I will reiterate what mike said. But we felt we owed it to you to share everything that we know. I can assure you that there was no other group of folks, not just the folks that worked last night, the folks that started the countdown, no other folks wanted to get this countdown started more than those people. I will turn it over to jackie. Jackie for those of you joining us on the phone come up press star want to get into the queue. First, we will take some questions in the room. Associated press. Probably for you, mike or jim. Is friday or monday even feasible because you are dealing with an engine . Might you need to replace this engine . Is this a problem unique to this . You said you didnt get the temperatures on any of them that you were looking for. What could be the worst case here . Mike friday is definitely in play. We just need a little bit of time to look at the data but the team is setting up for a 96hour recycle. They are Still Holding in the launch council figuration and preserving the option for friday, replenishing commodities out at Launch Complex 39b. You will see those activities starting tomorrow. Right now the indications dont point to an engine problem. It is in the bleed system, that thermally conditions the engines. We did change the diameter of that, where we did the green run testing to hear. To here. We never fully got into the engine bleed configuration through the prior wet dress attempts, and that is something that we talked about at the Agency Flight Readiness review, a known risk to our launch campaign. At the time we said we would not launch until we got through a demonstration of our ability to thermally condition the engines. We need that in order to start the engines and run them successfully. We just did not get there today. Again this really points toward an engine bleed issue on the core stage side, not on the engine or interface side. Jim, i dont know if you have anything to add. Jim we actually stayed loaded longer to try to figure it out, so that we were trying to save as much, as many cycles on the tank as we can. I think we tried to run it to ground as fast as we could. Once we were outside seeing we could launch, the way the pressure in the tank was going, ok, it is better to stop and regroup, stay in the 96hour that mike talked about and figure it out. So you did make it bigger. Jim we also did it, and you will hear from John Honeycutt, where we did the test in the flow. A little bit different. All of those decisions were made hoping for the benefit of physics that went with all of that, from the experts opinion. That is what we have to figure out. Jackie reuters. Thanks. Question for mike or jim. I know you said friday is in play. Given the magnitude of the issues, the combo of things you have to look at, likely that you launch on friday, unlikely . Can you give some clarification on whether you think this is related to the Quick Disconnect issue that you saw in the wet dress rehearsals . Mike you are asking about the likelihood of friday . Do we go on friday . Mike there is a nonzero chance that we will have a large opportunity on friday. [laughter] mike we really need time to look at all the information, data. We are going to play all nine innings here. Not ready to give up yet. Clarify a little bit whether this is related to what you were looking at in the wet dress rehearsals with the Quick Disconnect leak issue. Related, independent . Mike this is probably a question better answered by John Honeycutt, but during the wet dress rehearsal, we saw issues at both the fourinch and eightinch qd, in terms of our ability to retain enough pressure to properly seal those such that we didnt have a Hydrogen Leak. We never got to the engine bleed itself during the wet dress. We need that. So the qd problems that we saw during wet dress have largely been mitigated. In fact, the eightinch today was the issue. A little bit of leakage on that they managed to work through by slowing the fill and chilling it down, and that properly sealed it. We got a full load. We were not able to get a full load in our three wet dress attempts. The fourinch qd that we previously had problems with i think on wet dress four, worked just fine today. I would say that the qds really had no Material Impact on the hydrogen bleed set up. Jim, i dont know if you have anything to add. Jim exactly right, what i was trying to say earlier. We work to the eightinch problem, work that out. Fourinch, we could not pressurize because it was leaking. We did that today. I think we are in good shape. Jackie michael, cnbc. My question is for mike. Im curious to get more learnings on the others of things, the possibility of a rollback. Given the data you have seen so far, how likely does that seem . If you were to roll it back to the pad, where does that reset the timeline in terms of your guyss next launch opportunity . Mike that is getting ahead of our data reviews. We need the team to get rested and come back tomorrow. We will see what the data tells us. I will recycle a line from earlier. There is a nonzero chance. But we will do our best to see where the data leads us. If we can resolve this operationally on the pad, there will be no need for that. If we can resolve this operationally on the pad in the next 48, 72 hours, friday is definitely in play. We need to see what the art of the possible is. We need to team to digest what we have learned, and we will take it from there. Jackie ken with the new york times. This is for mr. Serafin. I wonder if you could give us a primer on the bleed work. Coming from the Hydrogen Tank to the engines, what was changed, why . Did anything like this occur during green run at stennis . Mike i will do for that one to John Honeycutt tomorrow. I know we increased the diameter of the bleed that is used to increase the flow of the engines. Beyond that, it would be getting out of my experience to talk about what other changes there were. If you could ask that to john tomorrow. Jackie jeff with space news. For Mike Sarah Finn you also mentioned an inner tank valve issue. Could you provide more details on what that is . If you didnt have the problem with the engine bleed on engine three, would that have been a constraint to launch alone . Mike we are still trying to understand what happened with the inner tank event but it was clear there was a leak at that valve. The challenge that that created, we want to increase the pressure in the tank in order to establish the hydrogen bleed. The vent was not cooperating with us. It was a delicate balance of maintaining the pressure to establish the bleed on all four engines. Engine three was not seeing the temperatures it needed. The vent valve complicated that. That is the point where the team thought it was appropriate to declare the scrub because we were just not going to make the twohour window. It was one of those situations where we knew we needed more time. Jackie thanks, mike. They are keeping you busy. Kristin with cnn. Rachel crane, cnn. Mike, you mentioned earlier you didnt see temperatures with all four engines you were anticipating. We heard a lot about engine three. Can you tell us about the temperatures you were sitting with the other engines, what the issue was . Mike the other engines were meeting the temperature range, were on trend to achieve what we would need to have a proper start. It was just engine three that was, for some reason, not getting to the proper temperature range. Jackie the fun we have Chris Davenport with washington post. Thank you so much. I guess for mike, what is the temperature that you need the rs 25 to be a
