Mejean Cline, Software Engineer and Configuration Management Analyst 

Mejean works on the Station Support Computing team, which updates and supports all of the computer systems on the International Space Station. 

She has a B.S. in computer engineering from the University of Houston. Growing up, she loved everything about technology and space but put off attending school to focus on making ends meet. Motherhood inspired Mejean to pursue her lifelong dream of being a part of NASA. Now, her message to women is, "Being a mom, having kids, having a family, doesn’t make you any less. In a sense, it makes you even more equipped.”

 

What is the most exciting part about your job?

The most exciting part of my job is being a part of the ISS Program. I have been in love with space exploration since I was a child, and I was always someone who wanted to understand how everything works. To have inside experience with the inner workings of software and equipment that is bound for the International Space Station and to see my own work contribute to that is something that excites me every day!

 

What motivates you? 

The people around me motivate me the most. My family, friends, and my wonderful colleagues who have become friends and family. They make me want to put my best foot forward in everything I do so I will make them proud.

 

What is a current project that you are looking forward to?

I am looking forward to our coming advances in automation! I have been here almost five years, and I have already seen the strides we have made to improve our system and our processes. I can see places where we can further streamline system builds and software development, and I can’t wait to see it realized!

 

Favorite podcast?

My favorite podcast is “In Search of Black History with Bonnie Greer.” It is a beautifully emotional and informative listen!

Dr. Diane Craig Davis, Mission Design Lead for Gateway Systems Engineering and Integration

Dr. Davis is an astrodynamicist in the Flight Mechanics and Trajectory Design branch. Currently, she designs spacecraft orbits with the Gateway Mission Design team at Johnson.

She is an expert on Gateway’s trajectory and can answer any questions pertaining to the spacecraft’s orbit. Dr. Davis previously worked at NASA's Jet Propulsion Laboratory, navigating spacecraft to Mars and performing ground-based radiometric orbit determination

 

What is the most exciting part about your job?

Identifying and solving the new challenges associated with the complicated cislunar dynamical regime is incredibly exciting. The Gateway orbit is really interesting; simultaneously affected by the Earth and the Moon, our near rectilinear halo orbit (NRHO) serves as an efficient staging location for missions to both the lunar surface and beyond cislunar space. I’m lucky to work with a fantastic team, and collaborating to uncover the secrets of NRHO dynamics is always fascinating, motivating, and a ton of fun. I’m excited to see the Gateway serve as the jumping-off point as our astronauts explore beyond Earth orbit.

 

What motivates you?

I’m motivated by finding patterns and solving puzzles, by getting to the bottom of mysteries, and by following unexpected paths to their roots and to new understanding. I’m motivated by spaceflight- we’ve barely scratched the surface of exploration. The better we understand the dynamics of bodies in the solar system, the better we’ll be able to get from one place to another, no matter where in space we are trying to go. I’m motivated by contributing to that knowledge and understanding.

 

What is a current project that you are looking forward to?

I am looking forward to the launch of the first Gateway elements, the Power and Propulsion Element, and the Habitation and Logistics Outpost, and seeing their low-thrust transit to the Moon via solar electric propulsion.

 

Favorite book?

The Lord of the Rings is my favorite book.

Dr. Sara R. Zwart, Deputy Manager for Nutritional Biochemistry Human Health and Performance

Dr. Zwart joined the Nutritional Biochemistry Laboratory in 2003. The group is charged with optimizing nutrition to improve astronaut health and safety on extended-duration space missions. To that end, operational activities include the evaluation of crew nutritional status before, during, and after flight, as well as conducting research to better understand the role of nutrition in human health during exposure to microgravity. Dr. Zwart has researched the effects of spaceflight on bone and muscle loss, iron metabolism, and ocular changes in astronauts. She has also led research efforts to understand the role of nutrition in ground-based analog studies – used to simulate aspects of space travel – including rotating cell culture, long-duration bed rest, undersea missions, and Antarctic winters.

Dr. Zwart received a B.S. in Biological Sciences from the University of Notre Dame and a Ph.D. in Nutritional Sciences from the University of Florida. She, her husband, and four children live in the Clear Lake area. 

 

What is the most exciting part about your job?

The most exciting part of my job is definitely when I get to look at data from our research studies.  It’s exciting to piece together the data at the end of a study, almost like putting a jigsaw puzzle together because there are so many pieces. The fun part is then to figure out how these pieces fit together and what picture the data tells us in the end. I’m motivated by the amazing team of people around me, and by our operations and research work that is ultimately focused on keeping astronauts healthy in space.  

 

What is a current project that you are looking forward to?

I’m looking forward to our new flight study, Flight B Complex, which will fly later this year. The concept of the study is based on over ten years of research, and we will be testing a countermeasure for spaceflight-associated neuro-ocular syndrome in astronauts. 

 

What motivates you?

I’m motivated by the amazing team of people around me, and by our operations and research work that is ultimately focused on keeping astronauts healthy in space.

 

Favorite free-time activity?

Spending time with my family, wool felting, and working with silver metal clay.
