Susan Schuh: Supporting the Humans in Human Spaceflight
Susan Schuh has dedicated her career to helping humans adapt to life beyond Earth.
As the Flight Crew Integration Operational Habitability (OpsHab) team lead in NASA’s Human Health and Performance Directorate at Johnson Space Center in Houston, Schuh leads efforts to understand what it is really like to live and work in space. She turns that information into progress by documenting astronauts’ feedback to improve current and future spaceflight missions.

Her work not only supports crews aboard the International Space Station, but also provides critical information for NASA’s preparations to explore more of the lunar surface than ever before through Artemis missions.
Her team supports astronaut inflight and postflight debriefs, capturing and analyzing feedback to help NASA apply lessons learned. They also manage one of NASA’s most valuable habitability tools, the Crew Comments Database. With more than 115,000 entries spanning 25 years of International Space Station missions, it is the only comprehensive and searchable record of crew feedback in existence. Every comment, from how astronauts sleep to how they organize supplies, becomes part of NASA’s collective learning.
“The Crew Comments Database is my work pride and joy,” Schuh said. “It’s been an invaluable resource for operations and development and continues to lend itself to future exploration.”
Schuh’s path to NASA began with a mentor who saw her potential early on. While studying psychology at Flagler College in St. Augustine, Florida, she was introduced to human factors research by Dr. Gerald Gamache, whose work on the effects of the Chernobyl reactor explosion helped shape her understanding of how people function in complex environments.
While completing her master’s degree in human factors and systems at Embry-Riddle Aeronautical University in Daytona Beach, Florida, Schuh began her first internship at NASA in 2000. “Even from the first days of my internship at Johnson, I knew I was meant to be a part of this community supporting humans living and working in space,” she said.
Schuh left Johnson briefly to support human systems integration for the Navy and Air Force but returned in 2006. Since then, she has continued to shape how astronauts experience living and working in space.

Her mentor’s influence extended beyond Schuh’s technical work. “Dr. Gamache was also a community builder outside of his professional life, and I’d like to think some of that rubbed off on me,” she said. That inspiration led her to found the Johnson Parenting community in 2020, which now includes more than 600 members who share support and resources for working parents across the center.
Schuh has learned that her work is about more than data—it is about people. “Being purposeful in taking time to listen and be willing to learn and collaborate has made all the difference for me,” she said. “Over time, I’ve learned a lot about perseverance. This work has required it, encouraging folks to utilize the Crew Comments Database and keeping the feedback process empowered and robust.”

She is most proud of her family, known as Team Schuh—her husband, Scott, who works on the Orion Ascent Abort Mode Team, and their three daughters, Wilhelmina, Lorelei, and Franny. “They’re the reason I keep striving to balance work, family, and everything in between,” she said.
Finding that balance has been an ongoing struggle for her. “One of my biggest professional challenges, especially in the last 14 years since my oldest daughter was born, has been finding work-life balance,” she said. “I often struggle with creating boundaries and calling it a day at a reasonable time. I won’t pretend I have the secret recipe, but I’m working on it for sure.” Schuh credits the Johnson Parenting community for helping her and others along the way.

Outside of work, Schuh finds peace in the water and in nature. Her father, who worked in underwater engineering, taught her to scuba dive when she was 11. “We’ve taken some amazing multi-day trips together, including multiple visits to Cay Sal Bank,” she said. “He’s my favorite dive buddy, and I look forward to many more dive trips with him.”
Looking ahead, Schuh hopes to pass on that same sense of purpose she has found at NASA to the next generation. “Make connections and nurture them. It’s always cool to be kind,” she said. “Stay true to yourself and your values. Tell the people you admire how and why they inspire you.”

This System Reveals How Super-Earths Are Born
One of the best things about being able to see thousands of exoplanetary systems is that we’re able to track them in different stages of development. Scientists still have so many questions about how planets form, and comparing notes between systems of different ages is one way to answer them. A new paper recently published in Nature by John Livingston of the National Astronomical Observatory of Japan and his co-authors details one particularly interesting system, known as V1298, which is only around 30 million years old, and hosts an array of four “cotton candy” planets, which represent some of the earliest stages of planet formation yet seen.

Final Steps Underway for NASA’s First Crewed Artemis Moon Mission
As NASA moves closer to launch of the Artemis II test flight, the agency soon will roll its SLS (Space Launch System) rocket and Orion spacecraft to the launch pad for the first time at the agency’s Kennedy Space Center in Florida to begin final integration, testing, and launch rehearsals.
NASA is targeting no earlier than Saturday, Jan. 17, to begin the multi-hour trek from the Vehicle Assembly Building to Launch Pad 39B. The four-mile journey on the crawler-transporter-2 will take up to 12 hours. Teams are working around the clock to close out all tasks ahead of rollout. However, this target date is subject to change if additional time is needed for technical preparations or weather.
“We are moving closer to Artemis II, with rollout just around the corner,” said Lori Glaze, acting associate administrator for NASA’s Exploration Systems Development Mission Directorate. “We have important steps remaining on our path to launch and crew safety will remain our top priority at every turn, as we near humanity’s return to the Moon.”
As with all new developments of complex systems, engineers have been troubleshooting several items in recent days and weeks. During final checkouts before rollout, technicians found a cable involved in the flight termination system was bent out of specifications. Teams are replacing it and will test the new cable over the weekend. Additionally, a valve associated with Orion’s hatch pressurization exhibited issues leading up to a Dec. 20 countdown demonstration test. On Jan. 5, the team successfully replaced and tested it. Engineers also worked to resolve leaky ground support hardware required to load gaseous oxygen into Orion for breathing air.
Rollout
Once the integrated rocket and spacecraft reach the launch pad, NASA will immediately begin a long checklist of launch pad preparations, including connecting ground support equipment such as electrical lines, fuel environmental control system ducts, and cryogenic propellant feeds. Teams will power up all integrated systems at the pad for the first time to ensure flight hardware components are functioning properly with each other, the mobile launcher, and ground infrastructure systems.
Once complete, the Artemis II astronauts, NASA’s Reid Wiseman, Victor Glover, and Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen, will conduct a final walkdown at the pad.
Wet dress rehearsal, tanking
At the end of January, NASA will conduct a wet dress rehearsal, which is a prelaunch test to fuel the rocket. During wet dress, teams demonstrate the ability to load more than 700,000 gallons of cryogenic propellants into the rocket, conduct a launch countdown, and practice safely removing propellant from the rocket without astronauts onsite.
During launch, a closeout crew will be responsible for securing astronauts in Orion and closing its hatches. The closeout crew also will use this rehearsal to practice their procedures safely without astronauts aboard the spacecraft.
The wet dress rehearsal will include several “runs” to demonstrate the launch team’s ability to hold, resume, and recycle to several different times in the final 10 minutes of the countdown, known as terminal count.
The first run will begin approximately 49 hours before launch when launch teams are called to their stations, to 1 minute 30 seconds before launch, followed by a planned three-minute hold and then countdown resumption to 33 seconds before launch – the point at which the rocket’s automatic launch sequencer will control the final seconds of the countdown. Teams then will recycle back to T-10 minutes and hold, then resume down to 30 seconds before launch as part of a second run.
While NASA has integrated lessons learned from Artemis I into the launch countdown procedures, the agency will pause to address any issues during the test or at any other point should technical challenges arise. Engineers will have a close eye on propellant loading of liquid hydrogen and liquid oxygen into the rocket, after challenges encountered with liquid hydrogen loading during Artemis I wet dress rehearsals. Teams also will pay close attention to the effectiveness of recently updated procedures to limit how much gaseous nitrogen accumulates in the space between Orion’s crew module and launch abort system hatches, which could pose an issue for the closeout crew.
Additional wet dress rehearsals may be required to ensure the vehicle is completely checked out and ready for flight.
If needed, NASA may rollback SLS and Orion to the Vehicle Assembly Building for additional work ahead of launch after the wet dress rehearsal.
Next steps toward launch
Following a successful wet dress rehearsal, NASA will convene a flight readiness review where the mission management team will assess the readiness of all systems, including flight hardware, infrastructure, and launch, flight, and recovery teams before committing to a launch date.
While the Artemis II launch window opens as early as Friday, Feb. 6, the mission management team will assess flight readiness after the wet dress rehearsal across the spacecraft, launch infrastructure, and the crew and operations teams before selecting a launch date.
To determine potential launch dates, engineers identified key constraints required to accomplish the mission and keep the crew inside Orion safe. The resulting launch periods are the days or weeks where the spacecraft and rocket can meet mission objectives. These launch periods account for the complex orbital mechanics involved in launching on a precise trajectory toward the Moon while the Earth is rotating on its axis and the Moon is orbiting Earth each month in its lunar cycle. This results in a pattern of approximately one week of launch opportunities, followed by three weeks without launch opportunities.
There are several primary parameters that dictate launch availability within these periods. Because of its unique trajectory relative to subsequent lunar landing missions, these key constraints are unique to the Artemis II test flight.
- The launch day and time must allow SLS to be able to deliver Orion into a high Earth orbit where the crew and ground teams will evaluate the spacecraft’s life support systems before the crew ventures to the Moon.
- Orion also must be in the proper alignment with the Earth and Moon at the time of the trans-lunar injection burn. The Artemis II trans-lunar injection burn places Orion on course to flyby the Moon, and also sets it on a free return trajectory, in which the spacecraft uses the Moon’s gravity to send the spacecraft back to Earth without additional major propulsive maneuvers.
- The trajectory for a given day must ensure Orion is not in darkness for more than 90 minutes at a time so that the solar array wings can receive and convert sunlight to electricity, and the spacecraft can maintain an optimal temperature range. Mission planners eliminate potential launch dates that would send Orion into extended eclipses during the flight.
- The launch date must support a trajectory that allows for the proper entry profile planned during Orion’s return to Earth.
The periods below show launch availability through April 2026. Mission planners refine the periods based on updated analysis approximately two months before they begin and are subject to change.
Launch Period Jan. 31 – Feb. 14
- Launch opportunities February 6, 7, 8, 10, and 11
Launch Period Feb. 28 – March 13
- Launch opportunities March 6, 7, 8, 9, 11
Launch Period March 27 – April 10
- Launch opportunities April 1, 3, 4, 5, 6
In addition to the launch opportunities based on orbital mechanics and performance requirements, there are also limitations on which days within a launch period can be viable based on commodity replenishment, weather, and other users on the Eastern Range schedule. As a general rule, up to four launch attempts may be attempted within the approximate week of opportunities that exist within a launch period.
As the agency prepares for its first crewed mission beyond Earth orbit in more than 50 years, NASA expects to learn along the way, both on the ground and in flight, and will let the readiness and performance of its systems dictate when the agency is ready to launch.
As part of a Golden Age of innovation and exploration, the approximately 10-day Artemis II test flight is the first crewed flight under NASA’s Artemis campaign. It is another step toward new U.S.-crewed missions to the Moon’s surface, leading to a sustained presence on the Moon that will help the agency prepare to send the first astronauts – Americans – to Mars.
