Patrick Loehrer: 

Hi, I'm Patrick Loehrer. I'm Director of Global Oncology and Health Equities at Indiana University.

Dave Johnson:

My name's Dave Johnson. I'm at UT Southwestern in Dallas. Patrick, we're excited to be back for another segment of ASCO's Educational Podcast, Oncology, Etc. We have two very special guests today, Drs. Ellen Baker and Robert Satcher, oncologist and former astronauts. So I predict this will be an out of this world segment.

Patrick Loehrer:

It's starting out pretty slow right now, with that one. Thank you though. 

Dave Johnson: 

Well, listen, this should be a great segment. But before we get started, do you have a favorite astronaut book? 

Patrick Loehrer: 

Well, the one I read this summer was called American Moonshot by Douglas Brinkley, and it basically took the story of John F. Kennedy and how the space race happened from 1960 and actually earlier than that, into getting onto the moon. It was really, I thought very extraordinary. 

Dave Johnson: 

So, I haven't read that yet. My favorite would be Rocket Boys by Homer Hickam. I thought that was a fantastic book about his life growing up in West Virginia and ultimately, becoming a NASA engineer and rocket scientist. So that was really great.

Patrick Loehrer: 

I read that several years ago after you recommended it. They made a movie out of that. 

Dave Johnson: 

Yeah, I think October Sky was the name of the movie. Yeah.

>Patrick Loehrer:

Yeah, it's a terrific book.

Dave Johnson:

Well, why don't we introduce our guests? You want to start with Dr. Baker? 

Patrick Loehrer:

Oh, sure. It's my pleasure to introduce Dr. Ellen Baker. I have known Ellen over the years through interactions in global oncology. She was born in Fayetteville, North Carolina, graduated from Bayside High School in New York, got a bachelor of arts degree in geology from the State University at Buffalo. A doctorate in medicine for Cornell, masters in public health at UT Public Health, and then trained in internal medicine at UT San Antonio.

And during her residency, she decided to join in the NASA program as a medical officer. And it was actually, she did a residency around the same time I did, and I remember the space call for astronauts at that time. She was selected as an astronaut in may of 1984, had a variety of jobs. She's logged more than 680 hours in space and has been a mission specialist. She retired from NASA in 2011 and is Director of the MD Anderson project, Echo Program in which he does projects in rural Texas, as well as Zambia, Mozambique, in Central and South America. It's such a great pleasure to have you here today, Ellen. 

Dr. Ellen Baker: 

Thank you, Patrick. 

Dave Johnson: 

Our other guest is Dr. Robert Satcher, currently an Associate Professor in the Department of Orthopedic Oncology Division of Surgery at MD Anderson, as well. Dr. Satcher grew up in Hampton, Virginia. He's the son of a university professor and English teacher, so I'm sure they made him do all of his homework. He received a bachelor degree, as well as a PhD in chemical engineering from the Massachusetts Institute of Technology and received his MD degree from Harvard. By the way Patrick, Dr. Satcher enrolled at MIT at age 16 and graduated at the top of his class. Later, we'll find out what you were doing at age 16?

Patrick Loehrer:

I do have to interject that I was a mechanical engineer at Purdue, and it's like being in high school compared to chemical engineers.

Dave Johnson:

Yeah, there's a hierarchy in the engineering world for sure. Dr. Satcher's medical degree was followed by internship and residency in orthopedic surgery at the University of California, San Francisco. In addition, he did a post doc research fellowship again at MIT and University of California, Berkeley. And completed a fellowship in muscular skeletal oncology at the University of Florida, before joining the faculty at Northwestern in Chicago. You guys have a lot of connections it seems? Not satisfied with that massive amount of education and training, Dr. Satcher went on to NASA to train as an astronaut, culminating in a flight aboard the space shuttle Atlantis in November of 2009.

Apparently, he got a little bored cooped up in the shuttle because he took a couple of space walks, which I'd like to know more about. In fact, I read on NASA's website that he did some lubricating on one of his walks. I'm not sure what that's about, but I assume there's not a lot of gas stations in space. I also read that he repaired one of the robotic arms, which seems perfect appropriate for an orthopedic surgeon. You'll have to tell us more. Anyway, while these achievements would be enough for most people, it only begins to scratch the surface of the many accomplishments of Dr. Satcher's career to date. 

I really can't cover it all, but our audience should know that Dr. Satcher's has been involved in a number of community activities, as well, ranging from his involvement in Big Brother for Youths at Risk, counseling program, to serving as a lay minister in his church. He's also undertaken a number of medical mission trips to underserved areas in countries, such as Nicaragua, Venezuela, Nigeria, and Gabon, where he once served as a Schweitzer fellow at the Albert Schweitzer Hospital in Lambaréné. Dr. Satcher, welcome to Oncology, Etc., we very much appreciate your joining us.

Dr. Robert Satcher:

Thanks Dave. Glad to be here.

Dave Johnson:

Perhaps I'll start by asking the two of you, if you could give us just a little bit about your background, other than what we've stated and what got you interested in medicine and how you got interested in space? Dr. Baker, maybe we'll start with you?

Dr. Ellen Baker:

I've always been interested in space. I was a child of the '60s, and I think one of the very memorable parts of the '60s was the US Space Program. It was a fairly tumultuous decade in the US, I think otherwise, and the space program was really literally a shining star. However, there were no girls in the space program at that time. Right? There were no girl astronauts and so I thought about it, but it didn't seem like it was even possible. I come from a family of medical people. My mother was a nurse, my father was a doctor, my brother is a doctor, and so that had a lot of influence, I think, in my choosing to go into medicine. And in fact, my brother is an oncologist and though I am actually not an oncologist, I've been hanging around with him long enough that some people think I'm an oncologist. So I think that's what got me pointed in that direction.

Dave Johnson:

Your brother is Larry Schulman, by the way, right? Humanitarian of the Year Award from ASCO, a couple years ago.

Dr. Ellen Baker:

It is, yes, and he is a great humanitarian. I was actually at my last year of medical school when I saw a little article in the New York Times that NASA was selecting new astronauts and women and minorities were urged to apply. And I kind of filed that away and went off to do my medicine residency and at the end of my residency, I applied to work for NASA as a physician. And that's how I got to Houston and to Johnson Space Center.

Dave Johnson:

Dr. Satcher, what about yourself?

Dr. Robert Satcher:

I got interested in space and being an astronaut when I was a kid too, and I was watching astronauts land on the moon. And I was sitting there listening what Ellen was saying and yeah, it was a time where all the astronauts were of course, white males and I didn't see myself there walking on the moon, but I knew it was something that I would really like to do, but didn't really see a way either, at the time. So it really was with the shuttle era that women, people from underrepresented groups finally had the opportunity to become astronauts.

And right around the same time too, was when I was starting as an undergraduate at MIT and had the good fortune of meeting Ron McNair, who got his PhD from MIT. And that was the first time I ever saw someone who looked like me, who was an astronaut and that planted the seed that maybe I could do that one day. I also come from, as you mentioned, a family that values education and we've got a number of physicians in our family. Most famously my uncle, Dr. David Satcher, who was Surgeon General of the Clinton Administration. And I always remember, this is a funny story I like to tell if he's listening.

When I was going around getting advice on whether or not I should stick with medicine or think about applying to become an astronaut, he advised me just to stick with medicine. So didn't take his advice, this is the one time I didn't, but I did take his advice, in terms of going to medical school. And I wound up applying to become an astronaut, right actually, before the Columbia accident and so they actually paused taking astronauts for a number of years. And in those years, actually that's when I went to Northwestern and was on faculty there. So they opened it up again and that's when I submitted my application and I was in Chicago and was selected from there.

Dave Johnson:

There's a number of questions that spill off from that. You guys may know David Wolf, who's an astronaut, who's from Indiana University. I had him in my clinic when he was a medical student and as I always do, I basically say, "What do you want to do when you grow up?" And he said, "I want to be an astronaut." And I just smiled and I don't think I ever went back in the room with him, I just figured, "This guy is a flake, what's going on with him?" And I think he's logged more space miles than just about anybody, he's an incredible human being. And again, if he's listening, you're terrific. David.

Patrick Loehrer:

I just have to ask this as a boyhood thing, because I did contemplate being an astronaut because I was an engineer and MD just like you were Ellen and so were you Bobby. But it hit me, one is, you have not to be afraid of heights, I think. And then, you have to be willing to go around in a circle a thousand times a minute and not throw up. But in the training there, did any of that stuff bother you or was this no big deal?

Dr. Ellen Baker:

That sounds a little like Hollywood and not so much like the real thing, actually. In the early days of the space program, they did put astronauts in rotating chairs. I'm not exactly sure why? But we don't do that anymore. I would say that the training is rigorous, but it's not unreasonable. I don't know what you think, Bobby? It's fairly predictable. And I will put a little shout out for Purdue, which maybe has one of the highest number of astronauts of any university outside the military academies. I don't know if that's true now, but 10 or 15 years ago, we just had a large number of engineers from Purdue who were in the astronaut office.

Dr. Robert Satcher:

I agree, the training is not quite how it's portrayed sometimes in the media. The question I get asked from my doctor friends a lot, "I guess you can't be claustrophobic going into space because you're in the space capsule." And that really does deter a significant number of people, probably more than myself or Ellen appreciate because I'm always surprised when I get that question.

Dave Johnson:

But I'm 100% sure I couldn't be an astronaut if claustrophobia is an issue because I can't stand to be in an elevator.

Dr. Ellen Baker:

Let me step back a little, I don't want anybody to get discouraged. But you'd be surprised at how many pilots have a fear of heights if they're not encased in an airplane. So fear of heights is not necessarily something that you might worry about if you're an astronaut. And I disagree with you Bobby, I don't think space vehicles are claustrophobic. It's not like being in a submarine, which I would find very claustrophobic. Particularly in the shuttle because we actually had great windows and great views and we didn't feel confined. I don't know what you think Bobby, but I didn't think it was like being in a cave or closet or a submarine.

Dr. Robert Satcher:

Yeah, I definitely agree with that, the views are spectacular.

Patrick Loehrer:

So William Shatner just went up and had a brief stint in space and is now considered an astronaut, but he came back with such a sense of awe. Can you describe a little bit what it's like, the view from up there and how does it leave you, particularly your first time up in space?

Dr. Robert Satcher:

The words don't completely capture it. The colors are so vivid, the view is so breathtaking. It's really impressive seeing the Earth, not only at daytime, but at nighttime and it goes beyond. It's one of a few things I always tell people, that really exceeded my expectation, in terms of what my preconceived notion of what it would be. And ever since going, that's what's so addictive about going into space, it makes you want to go back just to see that again and experience it again. The closest that I've come to seeing anything like that is, they have these new virtual reality experiences, where they actually got footage that they shot in high-def on the space station, outside the space station. It comes close, in terms of the look but it still doesn't fully capture it because the colors and everything, aren't as clear and crisp as it is when you're there. Because you're in the vacuum of space and there's nothing interfering with it and it's just spectacular.

Dr. Ellen Baker:

Yeah. I'll jump in here too and I absolutely agree with Bobby. And the other thing is, you orbit the Earth every 90 minutes, so you cover a lot of ground and you see a lot of the planet and in that one orbit, you get a sunrise and a sunset. So you orbit the Earth 16 times a day and get 16 sunrises and sunsets, so every 45 minutes the sun is either coming up or going down. It's really hard to know what time of day it is, in terms of your work day in orbit, but it's just magnificent. And it did give me a sense that we're all from the same planet and of course, it makes me wonder why we can't all get along better?

Patrick Loehrer:

I think people our age remember a few things, we remember the day Kennedy was shot. We remember the landing on the moon with Neil Armstrong. We also sadly, also remember the Challenger disaster and where we all were at that point in time. Ellen, you were an astronaut at that time.

Dr. Ellen Baker:

I was.

Patrick Loehrer:>

Can you reflect a little bit about that, if you can? I'm not sure I could do it without getting emotional, if I was there.

Dr. Ellen Baker:

Yeah, I was actually at work of course, and watching the launch and it was just devastating. Obviously, I knew everybody on board, I knew their families very well. And I have to say, we knew flying in space was risky, but we were still pretty unprepared for Challenger and for Columbia. It is something that I still think about. As weird as it might sound, I actually rescued the plant from Dick Scobee's office. He was the Commander of Challenger and I still have it growing. So it's a reminder that he was a good friend and a good colleague, it was a terrible blow, as was the Columbia accident. In that same tradition, I have African violets by my sink that were in Laurel Clark's office and Laurel was a physician who was aboard the Columbia, as well as Dave Brown, who was also a physician on the Columbia.

Dave Johnson:

That's an amazing tribute to both of your colleagues. It's very touching to hear that. I wonder if the two of you could share with us, what you actually did on your missions scientifically? How did you use your medical knowledge, if at all? And Robert, what about your oncologic knowledge, was that useful at all?

Dr. Robert Satcher:

Fortunately, no use for the oncology training in space. I got to use the orthopedic training. One of the most common problems is back pain the first few days when you're in space. We attribute it to, you're going into weightlessness and all of a sudden, there's these fluid shifts, you get more fluid in your inner discs, everybody gets taller.

Dave Johnson:

Well, let's send Patrick to space.

Patrick Loehrer:

We need to get up there soon, Dave.

Dr. Robert Satcher:

Yeah. Actually, during our visit, we measured everybody's height just so that we know what that change was and we did do a experiment actually, that my background came very useful for. We were looking at the effects of bisphosphonate on bone loss. So bisphosphonates, well, everybody knows, this is ASCO, a class of drugs, anti-absorptives, used in patients with bone metastasis. It was actually being tested in rats, thinking about countermeasures for keeping people from losing bone in long duration, space trips. Unfortunately, bisphosphonates come with a lot of effects.

But it did seem to work, in terms of the bone mass, which is induced by weightlessness in rats. And then finally, I was the crew medical officer for my group because I was the only MD up there in our crew. Ellen probably was the same in hers. So, what that involves is, NASA was one of the first places to pioneer use of telemedicine. So, you're basically, communicating with the flight surgeons on the ground every day, talking about what sort of medical issues there are with the crew and getting their recommendations for dealing with whatever it is. So yeah, being a doctor actually came very much handy.

Dave Johnson:

I was going to ask both of you. During your flights, did you encounter any medical emergencies without violating HIPAA? I mean, did you have to do an appendectomy?

Dr. Ellen Baker:

No appendectomies and fortunately, no emergencies, astronauts are pretty well scrutinized and examined before flights. And I think the best insurance against a medical problem in space is to send crews that are really fit and really healthy. And of course, there's always the risk of things like trauma, but the risk is actually fairly low. So no emergencies on my flight.

Patrick Loehrer:

There's no RVUs up there are there, that you have to worry about billing or no?

Dr. Robert Satcher:

No, we didn't have to deal with third-party payers.

Patrick Loehrer:

This is looking more and more like a job I want to pursue here, I'm going to be taller and there's no billing. This is great.

Dave Johnson:

I want to hear from Ellen, what sort of experiments she was involved in and how her medical background helped her assist with that?

Dr. Ellen Baker:

Yeah. People think, "Gee, if you're a doctor and you're an astronaut, they selected you to be a doctor in space." But in fact, astronauts are selected sort of generically. So once you come into the office, you're trained as an astronaut and Bobby and I were both mission specialists, as opposed to astronaut pilots. And so we received training on all sorts of different things. Bobby did a space walk. I trained for space walks, but never did one. We trained on the remote arm. We trained how to fix things when they were broken. I was actually a flight engineer on one of my flights.

But that aside, I was also the crew medical officer and on every flight astronauts participate in medical experiments, because we are trying to gather lots of information from very few people on the physiologic effects of space flight, particularly looking towards longer flights, perhaps back to the moon or to Mars. So I did participate as a subject, I was an operator in a few medical experiments, but the bulk of my responsibilities actually were not medical. And I think Bobby, maybe you would agree with that? We did have some flights that were designated as what I would call, space life sciences flights, but there was only a handful of them and I was not a crew member on any of those flights.

Patrick Loehrer:

Boy, I could spend another three hours on this and would love to hear more stories.
