SpaceFlight Insider continues its update of recent developments with NASAs Orion spacecraft; more specifically, public outreach efforts that the U.S. space agency is undertaking to prepare the nation for its return to exploring deep spacean undertaking it has not attempted since the historic Apollo 17 mission, which concluded in December 1972. During a recent event held at the AMRO Fabricating Facility in South El Monte, California, NASA astronaut Lee Morin had a chance to review progress being madeand to thank those who are working on these flight systems. <\/p>\n
When it comes to inspiring people about the U.S. efforts to explore the deep reaches of the Solar System, few people can inspire like an astronaut. SpaceFlight Insider spoke with NASA astronaut Lee Morin about what the space agency had him doing to provide not just an understanding of space but also an excitement for what awaits. <\/p>\n

SFI: For starters, youre at an event at the AMRO facilities right now, correct? <\/p>\n
Morin:Yes. <\/p>\n
SFI: How are you using this event to inform the public or maybe just the space community about NASAs new crew-rated spacecraft, Orion? <\/p>\n
Morin: We have a whole system of subcontractors, suppliers, and subcontractor supplier management at NASA, as you may know. And we have small businesses, suppliers, all over the country. And so as they are delivering our hardware, we generally have people that, you know, come and visit them. We take these opportunities to come and thank the team for their hard work, their craftsmanship, and we invite the media out and the local congressionals, mayors, the city people in El Monte; were here in South El Monte. Its a way to shine a light on the businesses doing this great work. It helps the employees. They have a sense of pride, I think, and theyre very proud to work on this program. So its a strategy we use to thank all the people that are helping us get to deep space. <\/p>\n
SFI: So lets talk a bit about that, then. Whats been the reaction of some of the people that youve met there today, Lee, in terms of meeting you and their work on Orion? How are they responding to being able to be involved with NASAs new crew-rated spacecraft? <\/p>\n
Morin: Everyone heres been very excited. You can see their faces light up. The fact that they get to go out and talk to an astronaut and have their picture taken in front of the hardware theyve built that one of my colleagues will be flying out beyond the Moon is very exciting. By my coming, it sort of puts a face on it for them in terms of their ultimate customer, and people that betting their lives on their handiwork and craftsmanship. <\/p>\n
I personally have an interest in machining. I was an amateur machinist, so I was treated to sort of a behind-the-scenes look and getting to look at some of the machines and talk to some of the people on the line that operate those machines. So for me, that was an exciting trip. But I know that having someone from NASA come out and have an interest in their contribution and what theyre doing means a lot to them as well. <\/p>\n
SFI: As much as youre inspiring the folks, I remember that Gus Grissom did a tour back in the Apollo days, and Gus was known for being a competent engineer, but not much of a spokesman. And he basically looked at the engineers and said, Do good work. What have they taught you? I know that any time you interact with folks, its always a two-way street. They get to be inspired by seeing the people who are going to fly on these exciting new spacecraft, but what have you personally taken away from this experience today? <\/p>\n
Morin:Well, I always get invigorated talking to the public, whether thats at a school or at a plant like this. I can just see the enthusiasm of the people. In their day-to-day lives theyre doing their jobs, but what theyre doing in the case here is something that culminates in an important milestone for the country. I think [Barbara Zelon] and her team do a great job conveying that to them: that their role is very important. And traditionally that outreach has been very important because that helps keep the quality up. <\/p>\n
If you have that human face on the parts, it really motivates the entire team to, as Gus said, Do good work. But it puts a personal face on it and it makes it a lot more real to them in terms of what their role is. Of course, the part that theyre building today, which is this window panel, this very recognizable panel to many people because its the contour of the windows that you can see from the outside so its a very, very visible part. Of course, theyre building a lot of other parts, which are less visible but are just as important. <\/p>\n
SFI: So you saw where the windows being worked on. Could you tell us about some of the other elements that you got a chance to review today? <\/p>\n
Morin:This companys specialty is making very large, very complicated aluminum panels, which are these curved sections. And it starts out with a big slab of metal, in some cases, its as much as six inches thick. Some of the panels they showed us today weighed as much as seven tonsyou know, these big pieces of metaland this company has this process where they remove a lot of that metal. <\/p>\n
In other words, you might end up starting with [a] 5,000-pound piece of aluminum, and after youve removed all of the metal, when youre done, the part might only weigh 300 pounds. So its a very subtractive process. What they do is they both remove metal, but then they also have to shape it and bend it in a very precise way back and forth, so its real craftsmanship, a real art form to be able to do that. And this company actually does it better than anybody else. And these panels are very important. <\/p>\n
In addition to this panel that is the structural member that holds the windows, so it has the cavities where the windows will be mounted, they also have panels for the tanks of the Space Launch System booster, which will be the largest rocket ever built. Thats the tanks that hold the liquid hydrogen. <\/p>\n
Very similar process: they start with a large slab of aluminum, mill rectangular depressions in it so that they remove most of the weight but keep a lot of the strength, then they roll that into a section and then a number of those are welded together down in New Orleansthey actually finish the tank. So thats basically what we saw, basically aluminum plates that were very intricately machined and shaped to these conical and cylindrical sections that are later joined to form spacecraft. <\/p>\n
SFI: Youve obviously had a lot of experience seeing a lot of this hardware produced. Could you provide our readers with some of the differences that youve noticed when youre looking at Orion compared to the stuff you saw produced for Shuttle and other programs? <\/p>\n
Morin:One of the things thats important to realize is Orion has been a very evolutionary process in terms of the production of the components. The particular piece that we were looking at [had]originally consisted of 37 separate parts. The initial prototypes were built in that way. By building those prototypes and studying them, they found out how not only to remove thousands of pounds of metal (so it went from 4,000 to 2,000 pounds), they also went from 37 separate pieces to, I believe, its six pieces. <\/p>\n
So now those six pieces can be welded together. And the process they did here with these parts [makes it] so that theyre much closer to final assembly, whereas the earlier partsthe companies here would make the parts and that part would require a lot more finishing or coatings and so forth would have to be done later. <\/p>\n

Lockheeds worked with its suppliers to optimize the part in terms of complexity and manufacturability and optimize the part to have more of the process done further up the supply chain, and very importantly, to minimize the weight. So the part does the same job, but it takes only half as much weight, which is so important when youre talking about these deep-space missions because the energy to get something to the Moon and back [makes weight] critical. If you can save some weight, you really got a lot of leverage out of that. <\/p>\n
Its an incremental use of a lot of modern machining methods, which are very intensively computer-based, and lots of new materials, and lots of incremental improvements where each little improvement doesnt seem like that big a deal in itself, but when you put dozens and hundreds of them together, it really adds up to a really significant advance in these components. <\/p>\n
SFI: If theres one thing that your experiences todaychecking out the work thats being done on Orionhas most intrigued you or the public should be made most aware of, what would it be? <\/p>\n
Morin:I think it was that the employees here presented me with a panel that they 3-D printed, which was a miniature (I think about 1:25 scale) model of the part that is on display in front of the auditorium here. The key point of that is that 3-D printing technology is infusing its way into every phase of manufacturing. Not that the panel itself is 3-D printed, but that more and more 3-D printing is being used as an aid to improve the design or to check parts for fit before you commit to a very costly part. Of course, were using 3-D printing a lot ourselves. <\/p>\n
My role is building the cockpit of Orion. We do 3-D printing because we make working models of the display system that the crews interact with. We built a lot of those prototypes with 3-D printing. This is a company that machines metal, and they are using 3-D printing in a big way, and the employees presented this panel to me today, which is a great memento. <\/p>\n
SFI: Lee, thank you for taking the time to speak with Spaceflight Insider today. <\/p>\n
Morin: It was fun, thanks! <\/p>\n
Morin spoke with the teams at AMRO Fabricating Corporation located in South El Monte, California. While there, he had the opportunity to review finished structural test article hardware panels. These had been arranged in order for each section of NASAs new super-heavy-lift rocketthe Space Launch System, or, as it is more commonly called, SLS. The SLS is the chosen launch vehicle that the space agency hopes will restore American independence of launching its astronauts into space when used in tandem with the Orion spacecraft, which is being produced by Lockheed Martin and Airbus. <\/p>\n
As is the case with any major initiative, a number of companies and agencies have been tasked with the production of both the SLS and Orion. One of these partners is AMRO, which ishelping to build panels for SLS core stage, the rockets launch vehicle stage adapter (LVSA) and the Orion spacecraft. <\/p>\n
Companies and agencies are made up of people, and people are aided in their efforts when they are inspired. NASA astronauts, perhaps better than any other agency official, help to get the word out to those manufacturing these vehicles as to how important their work is, considering that these astronauts are planning on one day using what those firmsproduce to get NASA back into the business of crewed space exploration. <\/p>\n<\/p>\n
