Melissa Harris’ official NASA portrait. NASA/Robert Markowitz With over 25 years of experience in human spaceflight programs, Melissa Harris has contributed to numerous programs and projects during key moments in NASA’s history. As the life cycle lead and Independent Review Team review manager for the Commercial Low Earth Orbit Development Program, she guides the agency through development initiatives leading to a new era of space exploration.
Harris grew up near NASA’s Johnson Space Center in Houston and spent time exploring the center and trying on astronaut helmets. She later earned her bachelor’s degree in legal studies from the University of Houston, master and subject matter expert certifications in configuration management, and ISO 9001 Lead Auditors Certification. When the opportunity arose, she jumped at the chance to join the International Space Station Program.

Other areas of support included the International Space Station Mission Evaluation Room and the EVA Crew Systems and Robotics Division managing changes for the acquisition and building of mockups in the Neutral Buoyancy Laboratory and Space Vehicle Mockup Facility in Houston. She then took a leap to join the Constellation Program, developing and overseeing program and project office processes and procedures. Harris then transitioned to the Extravehicular Activity (EVA) Project Office where she was a member of the EVA 23 quality audit team tasked with reviewing data to determine the cause of an in-orbit failure. She also contributed to the Orion Program and Artemis campaign. After spending two years at Axiom Space, Harris returned to NASA and joined the commercial low Earth orbit team.
Harris said the biggest lesson she has learned during her career is that “there are always ups and downs and not everything works out, but if you just keep going and at the end of the day see that the hard work and dedication has paid off, it is always the proudest moment.”
Her dedication led to a nomination for the Stellar Award by the Rotary National Award for Space Achievement Foundation.

Looking forward, she anticipates witnessing the vision and execution of a self-sustaining commercial market in low Earth orbit come to fruition.
Outside of work, Harris enjoys being with family, whether cooking on the back porch, over a campfire, or traveling both in and out of the country. She has been married for 26 years to her high school sweetheart, Steve, and has one son, Tyler. Her identical twin sister, Yvonne, also works at Johnson.

NASA’s SpaceX Crew-11 mission is set to launch a four-person crew to the International Space Station later this summer. Some of the crew have volunteered to participate in a series of experiments to address health challenges astronauts may face on deep space missions during NASA’s Artemis campaign and future human expeditions to Mars.
The research during Crew-11 includes simulated lunar landings, tactics to safeguard vision, and other human physiology studies led by NASA’s Human Research Program.
Select crew members will participate in a series of simulated Moon landings, before, during, and after their flight. Using a handheld controller and multiple screens, the astronauts will fly through simulated scenarios created to resemble the lunar South Pole region that Artemis crews plan to visit. This experiment allows researchers to evaluate how different gravitational forces may disorient astronauts and affect their ability to pilot a spacecraft, like a lunar lander.
“Even though many landing tasks are automated, astronauts must still know how to monitor the controls and know when to take over to ensure a safe landing,” said Scott Wood, a neuroscientist at NASA’s Johnson Space Center in Houston coordinating the scientific investigation. “Our study assesses exactly how changes in gravity affect spatial awareness and piloting skills that are important for navigating these scenarios.”
A ground control group completing the same tasks over a similar timeframe will help scientists better understand gravitational effects on human performance. The experiment’s results could inform the pilot training needed for future Artemis crews.
“Experiencing weightlessness for months and then feeling greater levels of gravity on a planet like Mars, for example, may increase the risk of disorientation,” said Wood. “Our goal is to help astronauts adapt to any gravitational change, whether it’s to the Moon, a new planet, or landing back on Earth.”
Other studies during the mission will explore possible ways to treat or prevent a group of eye and brain changes that can occur during long-duration space travel, called spaceflight associated neuro-ocular syndrome (SANS).
Some researchers suspect the redistribution of bodily fluids in constant weightlessness may increase pressure in the head and contribute to SANS. One study will investigate fluid pressure on the brain while another will examine how the body processes B vitamins and whether supplements can affect how astronauts respond to bodily fluid shifts. Participating crew members will test whether a daily B vitamin supplement can eliminate or ease symptoms of SANS. Specific crew members also will wear thigh cuffs to keep bodily fluids from traveling headward.
Crew members also will complete another set of experiments, called CIPHER (Complement of Integrated Protocols for Human Exploration Research), which measures how multiple systems within the human body change in space. The study includes vision assessments, MRI scans, and other medical exams to provide a complete overview of the whole body’s response to long-duration spaceflight.
Several other studies involving human health and performance are also a part of Crew-11’s science portfolio. Crew members will contribute to a core set of measurements called Spaceflight Standard Measures, which collects physical data and biological samples from astronauts and stores them for other comparative studies. Participants will supply biological samples, such as blood and urine, for a study characterizing how spaceflight alters astronauts’ genetic makeup. In addition, volunteers will test different exercise regimens to help scientists explore what activities remain essential for long-duration journeys.
After landing, participating crew members will complete surveys to track any discomfort, such as scrapes or bruises, acquired from re-entry. The data will help clarify whether mission length increases injury risks and could help NASA design landing systems on future spacecraft as NASA prepares to travel to the Moon, Mars, and beyond.
NASA’s Human Research Program pursues methods and technologies to support safe, productive human space travel. Through science conducted in laboratories, ground-based analogs, and aboard the International Space Station, the program investigates how spaceflight affects human bodies and behaviors. Such research drives NASA’s quest to innovate ways that keep astronauts healthy and mission-ready.
