00:00Once we get through today's activities, then the focus really is going to shift to entry.
00:05And I think the first graphic is important to show up here for some of those critical events.
00:11You know, the first one that we're really going to have to keep our eye on is crew module and
00:17service module separation.
00:18That's going to happen about 20 minutes before entry interface.
00:22Once we get through the separation of the service module, we're going to do one final burn.
00:27It's called our crew module raise burn.
00:30This is typically not a burn that's going to be required, but it's our final opportunity to fine-tune our
00:36flight path angle before entry interface.
00:39So we'll perform that about 16 and a half minutes before entry interface.
00:43Once that burn is complete, the spacecraft is going to make a couple of roll maneuvers.
00:48This will provide additional separation between the service module, which is headed for a destructive entry in the Earth's atmosphere,
00:55from the crew module, which obviously contains our four astronauts.
01:00Once those rolls are complete, the crew will go visors down, and then they will be in an isolated environment
01:06in their launch and entry suit until after splashdown.
01:10We'll hit entry interface at 400,000 feet, about 1,950 miles away from our landing site.
01:2124 seconds after entry interface will hit our blackout, which is the point at which the plasma has built up
01:29around the spacecraft such that it interferes with our ability for the transmitters on Orion to transmit telemetry.
01:37This is nominal.
01:38This is nominal.
01:39It will last six minutes.
01:41Once that six-minute blackout is done, Orion is going to be at about 150,000 feet, so still falling
01:47pretty quickly.
01:48We're going to be within a couple tens of miles of the landing site by that point.
01:53And then our focus is going to shift to deploying the parachutes.
01:57We've got two drogue parachutes that will deploy.
02:00It will be about 22,000 feet.
02:03That will slow us down to about 200 miles an hour.
02:05And then we'll deploy the three main parachutes.
02:08Those are the orange parachutes you see in the image.
02:10That will happen about 6,000 feet altitude, which will slow the spacecraft and her four inhabitants down to a
02:18gentle 20-mile-an-hour splashdown in the Pacific Ocean.
02:21We'll get the spacecraft powered down about 15 minutes after splashdown, and then I'm going to hand over to Lily
02:28Villarreal, our recovery director, for mission authority.
02:32Let's go to the next graphic, which has a little bit more detail on some of those events.
02:36Here's a plot of what entry is going to look like.
02:39You can see it's only 13 minutes from entry interface until splashdown.
02:42So it's going to happen pretty quick.
02:44And the flight control team here in Houston, we're going to be without comms with the flight crew for six
02:49of those minutes.
02:51So it's going to start quickly, and it's going to be over even faster.
02:58Next page.
03:01And then for a graphic of all the parachutes that are going to deploy, the first thing before we deploy
03:06the drogue parachutes,
03:08we have to jettison something called the forward bay cover.
03:11It provides the protection for all the parachutes, and that's what's going to get jettisoned at about 35,000 feet.
03:19There's a window for the jettison of the forward bay cover, so if it doesn't happen at 35,000, it
03:24can happen lower, as low as 24.
03:28And nominally, we actually expect it to happen closer to 24,000 feet.
03:34Next page.
03:36And then if you're looking for a little bit of insight on our approach trajectory, we're going to have entry
03:42interface a little bit southeast of Hawaii.
03:45And after we fly 1,957 miles over the surface of the Pacific Ocean, we'll be landing in our targeted
03:55landing site off the coast of California.
03:57Second graphic I have is a few days ago I showed you some imagery of the crew module images we
04:04got down from our first external survey that was right after the TLI burn.
04:08So we actually do another external survey on the way home.
04:12This is our inbound external inspection.
04:14So I think we've got the next slide.
04:17Yeah, so this is kind of two different views of the spacecraft.
04:21Again, did a comprehensive review of all the imagery that we were getting down off the crew module.
04:27No concerns, no issues seen that would make us have any pause for the reentry phase.
04:34Everything is in excellent condition for that entry.
04:37So that's our pretty crew module.
04:39I think we have a couple pictures of the service module as well.
04:41Yeah, so we obviously don't bring the service module home.
04:44As we mentioned, that gets separated, you know, about 40 minutes before we splash down.
04:49But we did get some nice imagery.
04:50And the next one I thought was interesting.
04:51It's a picture of the solar arrays, but it's actually the backside of the solar array, which we don't normally
04:56see.
04:56So anyway, poured over all this imagery, and everything looks really good for the return.
05:02Operations-wise, there's a few other things going on in the cabin.
05:05You know, one interesting test that we're doing today is when you pressurize the cabin, the panels and things that
05:11are connecting there, you know, kind of shift around a little bit.
05:14And so we're having a demonstration of can you actually remove some fasteners in those panels and put them back
05:19in?
05:19Do the structures still line up enough that you can do that?
05:22This is to help us prove out if we needed to do any kind of maintenance or contingency access to,
05:28like, our ECLA system.
05:29So we'll be looking at that today to see if that demonstration works out well.
05:34We're also doing some demonstration what's called 20 by 20 degree dead banding.
05:39This is pointing the spacecraft a little bit different throughout the day to test thermal responsiveness of the systems externally
05:46to see if we can expand our operating envelope for future missions.
05:51So, I guess some other things, we've collected a lot of data on this mission, we'll be getting a lot
05:55of that data back when it comes back, but did want to mention a couple things.
05:59We've consumed 2,964 pounds of fuel in the service module.
06:03We have 4,285 to go.
06:05So, clearly, we had put a lot of margin into this mission to make sure we could fly it properly.
06:129,855 commands have been uplinked.
06:14So, we've been busy for the flight control team and the MER team doing all of that.
06:19And then we mentioned the optical comm and how effective that has been in getting data down.
06:24122 gigabytes of data downloaded.
06:26That was a record.
06:27That was in a single day.
06:28That was today.
06:29And a total of over 312 gigabytes of data coming down on that optical comm system.
06:33So, that's been really helpful for us getting down to some of this beautiful imagery.
06:37Cabin is currently at a 76 Fahrenheit degree, so the crew is quite comfortable.
06:42Everything looks really well.
06:44And I think that's probably it for me.
06:48Spacecrafts continue to operate nominally, and we are hard at work monitoring it until it gets home.
06:53So, with that, I will hand it over to Lily.
06:55Okay, great.
06:57Thank you for joining us today.
06:58I'm currently at sea aboard the USS John P. Murtha with a joint NASA and military team who are ready
07:05to safely recover the crew once they splash down off the coast of California.
07:09The ship departed from Naval Base San Diego on time, and we are currently maneuvering the ship to the landing
07:15zone.
07:15Over the past couple of days, we have been completing final preparations on the ship, including training with the joint
07:22NASA and military team to refresh the skills and procedures that we've been practicing during underway recovery tests.
07:29I want to quickly walk you, however, through the process of how we will safely recover the Artemis II crew
07:35and the Orion spacecraft once they return from their trip around the moon.
07:39The ship and the small boats will be positioned at a safe distance at Splashdown until the team has determined
07:46that their path of travel will be clear of any of the jettison hardware that Rick talked about.
07:53At Splashdown, the crew in Houston will follow their post-landing procedures, while our divers maintain a distance of about
08:02120 yards to the capsule once we're cleared to go to the capsule.
08:05After handover from the flight director to the landing recovery director, the divers will approach Orion, and they will conduct
08:13assessments of the air and water surrounding the capsule, just to make sure that it's safe to approach and help
08:19the crew exit Orion.
08:21After ensuring the area is safe, they're going to go ahead and open the Orion hatch and help the astronauts
08:26from their seats to a large inflatable raft that we call the front porch.
08:31Once all four astronauts are on the front porch, we will tow the capsule away from the front porch, and
08:37the team will wait, pick up from Navy helicopters, which are deployed from the recovery vessel.
08:42Two helicopters are going to rotate, picking up all four crew members before they return to the recovery ship within
08:49a few minutes of each other.
08:51Once the crew has exited the helicopters, it will proceed to the ship's medical bay to undergo routine post-flight
08:57medical checkups.
08:59We expect to recover the crew and deliver them to the medical bay within two hours of Splashdown.
09:04With the crew safely out of the capsule and in tandem to the recovery, teams will work on towing Orion
09:12into the well deck of the ship,
09:13using procedures that were very similar to those that were used on Artemis 1.
09:17Once we have Orion safely inside and all the small boats are back on the ship, we will start making
09:24our return to Naval Base San Diego.
09:26Depending on our distance, by then, the Artemis 2 crew will fly off the ship back to shore, we anticipate,
09:34within 24 hours post-splashdown.
