CSPAN NASA Briefing On Artemis Mission To The Moon August 6, 2022

See a crowd of this size here. You will notice most of the day today has and most of your experience has been looking at artemis as a whole in the future Artemis One Mission will bring us very soon. At this time in our media, we are going to bring the a panel of experts to discuss the Artemis One Mission in more detail. We will discuss the mission operations, recovery, the capitol, European Service module and astronaut training preparing for artemis to and beyond. Joining us to provide marks and answer questions we have here the space center, rick, lead artemis director, artemis one entry flight director, debbie course, deputy manager and read wiseman, chief astronaut. Joining us remotely from the Kennedy Space center in florida, Melissa Jones, artemis one recovery director and joining us from the European Space agency in the netherlands, Service Model program manager. Thank you all for being here. We will start with a short presentation from each of our briefs before opening up for questions. We will take questions on our phone bridge as well as here in the room. Please raise your hand high so we can see you and to run the microphone over to you and ask the question when you have a microphone. For those on the phone, press star one so we can get to you and ask your questions. Well start with our experts here and ill hit it over rick and jed. Thank you and my name is rick, lead flight director for the Artemis One Mission. Before we start with our Mission Overview i want to take a moment and thank you all for taking out today. Our teams have been working hard for a very long time and this is special, we are excited and we want to make sure the public feels our excitement and heres our story and we realized we are relying on you completely to do that so thank you for coming out today and showing an interest in our mission so we will pick up with an overview of the mission and handed over to start the first part. The artemis one first plan will be august 29 october 10. Charlie and her team Launch Control center we will and over vehicle once they launch the vehicle launch 8. 8 Million Pounds we will our journey. We can have a graphic there. Once we start liftoff and the vehicle clears the tower we will start the program to bring the capitol headdown position much like we did and shuttle. About a minute in, who will experience maximum dynamic pressure so the engines for that. About two minutes into the flight, the rocket booster motor and an attached from the court stage in the atlantic. We continue to another three and a half minutes or so, the Service Module panel along with the logical system will expose the Service Model and capitol continuing on further throughout the flight, about eight and a half minutes where we have main engine, and then we will separate court stage from the combined orion and upper stage or interim control upper stage, that will continue on. Then about 18 minutes we will deploy the solar rays where i parse the batteries and it will take about 12 minutes to deploy. We will continue to our first burn performed by upper stage called the raise maneuver. Court stage puts us in orbit 16 nautical miles by 975 orbit so if we did nothing at that time to correct the small side and 16 orbit, the whole capitol would come back to the earth just like the course they just going to do in the pacific. We will perform that maneuver to 100 nautical miles approximately 51 minutes into the mission. The whole time upper stage will be in control of the stack. In the interim it will do several maneuvers to get to a solar friendly attitude to the spacecraft and some maneuvers to make sure the whole vehicle is thermally conditioned. Pressing on forward, once we have obtained safe orbit, it will continue on and final maneuver by upper stage would be the trans injection orbit maneuver by the upper stage, approximately an hour and 20, 30 minutes into the flight. About 18 minutes burn and will send us to the moon approximately quarter million miles away. Once we complete the injection maneuver and separate upper stage from the ryan spacecraft and my team will hand over to rick and he will start the majority of the mission there. If we could go to the next chart please. Theres no time to catch our breath, we really hit the ground running. On this first chart after we separate from the upper stage, it does a disposal burn which sends it contradictory to the moon, they will swing around the moon toward the sun. On his way to the moon, it will deploy a handful, secondary payloads. We have no interaction with those payloads. The thing we are concerned with his trajectories for their deployed so we can do an assessment on the potential recontact. We should have no concerns but we need to make sure its what we expect so with that, i want to get away from this chart. Lets go to the next chart take off the icp as part. Im going to talk through this, its 42 days and try to do it in a handful of minutes. By all means there will be plenty of times to ask questions after we are finished here. We hit first day hit the ground running. One of the first things we will do is a test of guidance and navigation control system, a set of gains used and the way they fire thrusters, normal attitude control and we need to make sure gains are set such that we dont damage solar rays. Thats one of the first things we do once we separate and then the first thing we are also going to the first of a handful of trajectory correction burned. This very first one we are going to check out orbital maneuvering system, a big engine we use. We want to check that out because the engine we use when we do big burn on the outbound power flyby and ill talk about that shortly but the first burn is a check out and it will get us moving ahead of the upper stage and satellites so we should get to the moon around two and a half hours before satellites and upper stage two so thats why theres no concern of recontact. On our way to the moon, we will do a series of outbound corrections, they are very small are designed to be small if we have dispersions because they bring didnt go as planned, we will make it up in a subsequent burn. We have four on the way to the moon and they set us up for outbound power flyby. That is the burn that will move orion and send it up to the retrograde orbit so when we do that burn and we go by the moon, we are going to be about 60 miles off the surface of the moon, it will be spectacular. We will be holding our breath. To that note, when it actually executes, orion will be on the other side of the moon and we wont have time with it so well be praying and holding our breath but confident all will go well. After that burn, a census up to the retrograde orbit. A couple days after the burn, will do what we call insurgent burn, retrograde orbit insertion and we will use the big engine to enter the retrograde orbit and once we are in that orbit, we will spend a little over two weeks there. Youve heard us talk about long past missions and short Class Missions, the only difference in those two types of missions are linked to state and the retrograde orbit. For short Class Missions, we just do a half laugh and we had court back. In the long grass we do it. And a half, a little over two weeks. While in the district retrograde orbit, we will do what we call orbit maintenance, smoke burned to keep orbit in sync. We will do that in the next two weeks and then distant retrograde departure burn, another large burn using engine that will send us back to the moon and on our way back we do what we call return trajectory corrections and we will do a series of those all the way back to earth. We have a couple of those and it sets us up for the return flyby, are most critical burn on the mission. If something happens with that and we dont execute it, then its a loss of the ryan capitol. We have to do that one but we plan accordingly and we can talk about that if you have questions. We do rps which sets up the inter interface, the area when we enter the atmosphere several days later and said the are splashdown off the coast of california. On the return trip back to the earth we do a series of correction burned i talked about and its all to make sure we hit the entry interface target as designed. Ive gone through the mission very quickly. Just so you know on those days we coast to the moon, we are doing a lot of activities, about mental flight test objectives to basically test the onboard systems. We are doing Public Affairs outreach everyday, maneuver, a selfie of orion with the moon in the background and some days try to catch earth rise, thats a spectacular image. Theres a couple milestones throughout the mission we enter this sphere of influence of the lunar taking effect. Its a milestone we will capture the Public Affairs imagery. When we get to the furthest away any human rated spacecraft has ever been as far as vehicles, we want to capture that at a Public Affairs event so we will be busy the whole mission. Its really quick but once we get back to earth we do rtc which sets up the entry interface and he can take you to the rest of us. As rick mentioned, the return power flyby maneuver is essentially orbit burn way back at the moon about a week before we enter the earths atmosphere. About 20 minutes before we enter the interface, we will separate you can go to the slide there that we have next slide. We will separate from the Service Model and once we perform that, we will get into proper orientation, command module for entry. We will do set burn after command module and Service Model separation, thats the shallow, the angle the command module is entering so it provides more separation from the Service Model which will dispose in the pacific ocean. We will start entry interface and we are doing a skip entry profile so we will hit entry interface at 400,000 feet and then immediately start to control the factor of the capitol such that we dip a little bit in the atmosphere and come back up out of the atmosphere a bit and then come back and so will have two blackout. Due to the plasma heating of the capitol. Once we get out of the second. , we will continue our journey toward splashdown site in san diego off the coast of san diego. We have the four they covered and i think the next slide is a better picture to show you the secrets. Once we get further down into the atmosphere, about 35000 feet the jettison brings out the drove shoes deployed around 24000 feet followed by 6800 feet in between 6800 and 5600 feet and we will continue down to 1500 feet where the orion capsule will do landing reorientation maneuver such that it will roll the capsule so we hit the waves of the ocean at the proper angle. Once we splashdown, we will leave the vehicle powered for about two hours and do some testing there, thermal testing to make sure we have adequate cooling for astronauts when we do eventually have them on board waiting to be picked up by the recovery crew. After that two hour period, we will powerdown the vehicle and hand over the vehicle to jones and her team, the Recovery Team on navy boats. I headed back to you. Thank you. Fortytwo day mission in 15 minutes, fantastic. Thanks for the detailed Mission Overview, lets go to debbie. Good morning and thank you for being here, its great to see a room full of people and the excitement about this mission. Exciting time for nasa and orion, been working on this for a long time and we look forward to where we are going to go on this mission 24 days from now heading back to the moon so its amazing. Lets go to the next animation, we got a graphic here to explain the pieces of the vehicle. Its made up of three main elements. Is there an animation we can show . Thank you. Its made up of three main modules, crew, launch a work surface and the service. You heard group module referred to as the command module, the civil capitol there. The services are actually made up about 1300 silica miles, similar to the bottom of the shuttle during shuttle days. Its covered in aluminum tape to help with thermal production so that is what you see on the outside. On the bottom you will see the heat shall we talk about being a primary test, 16 and a half feet in diameter, the biggest weve ever built. The group module has its own small system, several reaction control system that perform those type of maneuvers on the reentry when we have to orient to the right orientation for landing. Parachutes, 11 total parachutes you saw pictures of that deployed in a sequence time sequence to slope the vehicle down from about 350 miles an hour down to less than 20 when we hit the water. You will be happy we are hitting at that speed. We talk about the large abort system and Service Model when youre done using these vices to help separate and make the separations. When you go inside the cabin, he got Environmental Control and life support systems so everything that controls pressure, temperature and humidity inside the volume, that module is designed to hold for members for 21 days and this is our test flight so expect to learn a lot how these systems work. Inside the vehicle theres avionics systems, Guidance Navigation control Medication Systems which are a lot different than the gps you probably you. To get here today, it doesnt work outside of where we are going such a deep base network kind of system for communications and several payloads we are flying on this flight, several of which are in the crews seat, we wont be flying through, is assimilated human tissue and organs looking at Radiation Protection and environment, acceleration of the vehicle and how it affects the human body because our goal is for the crews flight and artemis for future flights will be this mission but we will add in Waste Management system and exercise equipment crew health and comfort and safety during the mission. Next slide. This is the crew module and Service Model located in our factory, this is before we install the launch abort system so artemis one, we are Testing Systems and capabilities and this will be the configuration and the vehicle available mostly during the mission we are talking. One of the Main Objectives youve heard is the heat shield, it is the vehicle comes back in about 25000 miles an hour and we end up but temperatures about 5000 fahrenheit, about half the temperature of the surface of the sun so very high temperatures. We have a block designed made up of these blocks adhering to skin and skeleton and we will test as the Main Objective then you would talk about the other objectives and you can see solar rays up against the vehicle. We do a survey wants deployed in looking how they respond to different engine firings to handle the vibration and lows throughout the profile, checking out guidance and navigation and control and the parachute systems as we come back in. Next slide. The next picture is the vehicle as it came into the vehicle, vertical Assembly Building here so is a lot different now. We got the group module and Service Module and launch abort system on top. Launch abort system didnt talk about that previously, its the designed to pull the crew capsule away in cases of emergency on the launch pad or during the absent phase so its made up of three rocket motors, first is abort and not hold the crewmember away. Very powerful zero to 400 miles an hour in two seconds so very quick. Really trying to outrun as outlets that might have an issue during lunch. At the top of the system is the attitude control motor and it separated from the hazardous, the crew module away and allows to get is so safe location. This would get the launch abort system. Artemis one, the motor is the only active order, we dont and on using other functions, we didnt put the motors on the vehicle but the just and water works every flight so either eventually you take it off whether in a normal white or emergency situation. Next slide. This is a picture rolling out for a wet dress rehearsal. Before we got here, every component and every system, every module on the spacecraft has been thoroughly tested. Weve done over 48 engine test between ox engines and main engine we talked about to make sure we have robust propulsion system, the parachute system which showed, 25 different drop tests we did, capsules and darts at the back of military aircraft making sure we can handle every parameter, things that shoot out or different wind conditions, looking at all of that in the program, literally thousands of hours of avionics offer testing in the laboratory here where the contractor is located we took the spacecraft to a thermal chamber about Glenn Research center, the armstrong test facility, its been over 47 days not Chamber Bring it out because in every aspect of the temperatures, the backing and pressures, acoustics, its a lot of time testing this component at the module level. If you been following artemis for a while, you know we did three flight test, who done to complete flight test of launch abort system, looking at performance from the pad and one was the abort, looking at it during the dynamic phase. Finally we had the flight test one that happened a few years ago that tested out most of the group module systems and without our Service Module. Here we are on the pad, this was the last picture we took before we roll back in. I love this photo, the moon in the background, our destination calling to us, a huge amount of collaboration and testing and energy and effort has gone into putting this together. We had id say three to 4000 suppliers every state of the United States so huge effort across the country. Also a Strong Partnership with our european on
