The International Space Station is humanity’s home in space and a research station orbiting about 250 miles above the Earth. NASA and its international partners have maintained a continuous human presence aboard the space station for more than 24 years, conducting research that is not possible on Earth.
The people living and working aboard the microgravity laboratory also are part of the research being conducted, helping to address complex human health issues on Earth and prepare humanity for travel farther than ever before, including the Moon and Mars.
Here are a few frequently asked questions about how NASA and its team of medical physicians, psychologists, nutritionists, exercise scientists, and other specialized caretakers ensure astronauts’ health and fitness aboard the orbiting laboratory.
How long is a typical stay aboard the International Space Station?
A typical mission to the International Space Station lasts about six months, but can vary based on visiting spacecraft schedules, mission priorities, and other factors. NASA astronauts also have remained aboard the space station for longer periods of time. These are known as long-duration missions, and previous missions have given NASA volumes of data about long-term spaceflight and its effects on the human body, which the agency applies to any crewed mission.
During long-duration missions, NASA’s team of medical professionals focus on optimizing astronauts’ physical and behavioral health and their performance to help ensure mission success. These efforts also are helping NASA prepare for future human missions to the Moon, Mars, and beyond.
How does NASA keep astronauts healthy while in space?
NASA has a team of medical doctors, psychologists, and others on the ground dedicated to supporting the health and well-being of astronauts before, during, and after each space mission. NASA assigns physicians with specialized training in space medicine, called flight surgeons, to each crew once named to a mission. Flight surgeons oversee the health care and medical training as crew members prepare for their mission, and they monitor the crew’s health before, during, and after their mission to the space station.
How does NASA support its astronauts’ mental and emotional well-being while in space?
The NASA behavioral health team provides individually determined psychological support services for crew members and their families during each mission. Ensuring astronauts can thrive in extreme environments starts as early as the astronaut selection process, in which applicants are evaluated on competencies such as adaptability and resilience. Astronauts receive extensive training to help them use self-assessment tools and treatments to manage their behavioral health. NASA also provides training in expeditionary skills to prepare every astronaut for missions on important competencies, such as self-care and team care, communication, and leadership and followership skills.
To help maintain motivation and morale aboard the space station, astronauts can email, call, and video conference with their family and friends, receive crew care packages aboard NASA’s cargo resupply missions, and teleconference with a psychologist, if needed.
How does microgravity affect astronaut physical health?
In microgravity, without the continuous load of Earth’s gravity, there are many changes to the human body. NASA understands many of the human system responses to the space environment, including adaptations to bone density, muscle, sensory-motor, and cardiovascular health, but there is still much to learn. These spaceflight effects vary from astronaut to astronaut, so NASA flight surgeons regularly monitor each crew member’s health during a mission and individualize diet and fitness routines to prioritize health and fitness while in space.
Why do astronauts exercise in space?
Each astronaut aboard the orbiting laboratory engages in specifically designed, Earth-like exercise plans. To maintain their strength and endurance, crew members are scheduled for two and a half hours of daily exercise to support muscle, bone, aerobic, and sensorimotor health. Current equipment onboard the space station includes the ARED (Advanced Resistive Exercise Device), which mimics weightlifting; a treadmill, called T2; and the CEVIS (Cycle Ergometer with Vibration Isolation and Stabilization System) for cardiovascular exercise.
What roles do food and nutrition play in supporting astronaut health?
Nutrition plays a critical role in maintaining an astronaut’s health and optimal performance before, during, and after their mission. Food also plays a psychosocial role during an astronaut’s long-duration stay aboard the space station. Experts working in NASA’s Space Food Systems Laboratory at the agency’s Johnson Space Center in Houston develop foods that are nutritious and appetizing. Crew members also have the opportunity to supplement the menu with personal favorites and off-the-shelf items, which can provide a taste of home.

NASA’s nutritional biochemistry dietitians and scientists determine the nutrients (vitamins, minerals, calories) the astronauts require while in space. This team tracks what each crew member eats through a tablet-based tracking program, which each astronaut completes daily. The data from the app is sent to the dietitians weekly to monitor dietary intake. Analyzing astronaut blood and urine samples taken before, during, and after space missions is a crucial part of studying how their bodies respond to the unique conditions of spaceflight. These samples provide valuable insight into how each astronaut adapts to microgravity, radiation, and other factors that affect human physiology in space.
How do astronauts train to work together while in space?
In addition to technical training, astronauts participate in team skills training. They learn effective group living skills and how to look out for and support one another. Due to its remote and isolated nature, long-duration spaceflight can make teamwork difficult. Astronauts must maintain situational awareness and implement the flight program in an ever-changing environment. Therefore, effective communication is critical when working as a team aboard station and with multiple support teams on the ground. Astronauts also need to be able to communicate complex information to people with different professional backgrounds. Ultimately, astronauts are people living and working together aboard the station and must be able to do a highly technical job and resolve any interpersonal issues that might arise.
What happens if there is a medical emergency on the space station?
All astronauts undergo medical training and have regular contact with a team of doctors closely monitoring their health on the ground. NASA also maintains a robust pharmacy and a suite of medical equipment onboard the space station to treat various conditions and injuries. If a medical emergency requires a return to Earth, the crew will return in the spacecraft they launched aboard to receive urgent medical care on the ground.

Unable to render the provided source NASA invites the public to virtually sail along with the Advanced Composite Solar Sail System‘s space journey using NASA’s “Eyes on the Solar System” visualization tool, a digital model of the solar system. This simulation shows the real-time positions of the planets, moons, and spacecraft – including NASA’s Advanced Composite Solar Sail System.
Solar sails use the pressure of sunlight for propulsion, angling toward or away from the Sun so that photons bounce off the reflective sail to push a spacecraft. This eliminates the need for heavy propulsion systems and could enable longer duration and lower cost missions. The results from this technology demonstration – including the test of the sail’s composite boom system – will advance future space exploration to expand our understanding of our Sun and solar system.
The Advanced Composite Solar Sail System, which launched in April 2024, and deployed its reflective sail in August, is currently orbiting approximately 600 miles (1,000 kilometers) above Earth and is frequently visible in the night sky to observers in the Northern Hemisphere. Fans of the spacecraft can look for the sail in the night sky using a new feature in the NASA mobile app. Visibility may be intermittent, and the spacecraft could appear at variable levels of brightness as it moves in orbit.
For more mission updates, follow NASA’s Small Satellite Missions blog.
NASA’s Ames Research Center in California’s Silicon Valley, manages the Advanced Composite Solar Sail System project and designed and built the onboard camera diagnostic system. NASA Langley designed and built the deployable composite booms and solar sail system. NASA’s Small Spacecraft Technology (SST) program office based at NASA Ames and led by the agency’s Space Technology Mission Directorate (STMD), funds and manages the mission. NASA STMD’s Game Changing Development program funded the development of the deployable composite boom technology.

Many unusual phenomena are witnessed in the sky, ranging from UFOs and mysterious orbs to figures from parallel universes. One notable incident occurred during a recent thunderstorm from an unknown location when amidst the raging storm, a powerful flash of lightning illuminates the night sky, revealing the haunting silhouette of a demon, caught mid-air.
While this eerie vision was likely a result of the lightning itself, some claim it resembled Raijin, the Shinto god of lightning and thunder, a chaotic being born of death who brings the world vital rains as well as chaos and destruction .
Regardless of the true nature of this event, it serves as a reminder that countless mysterious phenomena exist on and around our planet. Whether tied to the afterlife, parallel universes, intelligent extraterrestrial life, or folklore with roots in truth, most of these occurrences remain unexplained.

Reports of alien abductions first became widespread during the 1960s and 70s. Alleged abductees frequently described undergoing experimental procedures performed by extraterrestrial beings. Some even claimed that these aliens had inserted unknown objects into their bodies.
In many cases, these so-called "alien implants" are metallic and have been reported to emit radio frequency waves. Often, they are found attached to nerve endings within the body.
One of the most prominent figures in this field of research was Dr. Roger Leir, who passed away on March 14, 2014. Along with his surgical team, Dr. Leir performed 17 surgeries on individuals who claimed to have been abducted by aliens, removing 13 distinct objects suspected to be alien implants.
These objects were subjected to scientific analysis by prestigious laboratories, including Los Alamos National Labs, New Mexico Tech, and the University of California at San Diego. The findings have been puzzling, with some comparisons made to meteorite samples, and isotopic ratios in some tests suggesting materials not of Earthly origin.
One such case is that of Terry Lovelace, a former Air Force medic, who kept a disturbing secret for 40 years. In 2012, a routine x-ray revealed a small square object about the size of a fingernail which was buried deep in Terry's right leg the doctor had never see anything like it.
Then Terry suddenly remembered the terrifying experience he had tried to forget - an event during a camping trip at Devil's Den State Park that he had never spoken of, knowing no one would believe him without proof. Yet the evidence had always been there: a strange metal object embedded in his leg, something that was not man-made.
In 1977, Terry and a friend had an extraordinary encounter at Devil's Den State Park, where they witnessed a massive triangular craft. This experience resulted in missing time and unexplained injuries. Years later, Terry was faced with a difficult choice: reveal his story of alien contact or remain silent. His decision led him into conflict with powerful forces and uncovered a conspiracy that extended beyond our world.
While some remain skeptical, believing these implants are man-made and part of a secretive human agenda, Dr. Leir’s work, along with Terry Lovelace's experience at Devil’s Den and the mysterious object found in his leg, suggests that 'alien' implants may not be mere fiction.

For every NASA astronaut who serves as a public face of human spaceflight, there are thousands of people working behind the scenes to make the agency’s missions a success. Even the smallest tasks impact NASA’s ability to explore and innovate for the benefit of humanity.
The team of administrative assistants and secretaries who work at the Johnson Space Center in Houston are acutely aware of this fact.
Whether they are coordinating meetings, arranging travel, or preparing materials and information for Johnson’s leaders, this team of over 90 individuals takes pride in providing critical support for the agency’s programs and managers. “We work hand-in-hand with management to get them where they need to go and ensure they have what they need to continue doing their important work,” said Carla Burnett, an executive assistant in the Center Director’s Office who is also the lead for all of Johnson’s administrative staff.
Carla Burnett participates in NASA’s celebration of the 60th anniversary of President John F. Kennedy’s historic Moon speech, held at Rice Stadium in Houston on Sept. 12, 2022. Image courtesy of Carla Burnett Burnett has turned her long-standing passion for administrative work into a 41-year career at Johnson. She was just a youngster when she started working in the Astronaut Office mailroom – an opportunity that came through her high school’s Office Education Program. “Being a meek and mild high school student, sitting there with the astronauts, going through all of their fan mail – I was in awe! It was an absolute honor,” she said. That experience and earning recognition as her high school’s Office Education Student of the Year confirmed for Burnett that administrative work was the right career path for her. She said that fidelity and perseverance launched her from the Astronaut Office mailroom to a position as a crew secretary for two space shuttle flights. “Being a servant and helping others is what I really love about administrative work,” she said.
Today, Burnett supports Johnson’s senior executives and serves as a central resource for the rest of the administrative team. “They are all very self-sufficient and work within their own organizations,” she explained, but she may coordinate team-wide meetings, celebrations, or trainings, and she is always available to help answer questions. “We work consistently as a cohesive team. We are knowledgeable and, may I add, exceptional at what we do because we do it for the benefit and success of our Johnson family, NASA, and a plethora of communities!”
Burnett’s dedication to service is reflected across the administrative team, as is a commitment to caring for others. Edwina Gaines, administrative assistant for the Extravehicular Activity and Human Surface Mobility Program, said that being an instrument of team success and the opportunity to build long-lasting friendships are the most rewarding parts of her job. “That connection to people is important,” she said. “It’s important for me to know who I’m supporting or working with.”
Edwina Gaines snaps a selfie during a professional development event for administrative professionals in 2023. Gaines joined the Johnson team as a contractor nearly 20 years ago thanks to an opportunity that arose from her volunteer work at church. A church partner, the Houston Area Urban League, was helping a NASA subcontractor fill a secretarial position through the Small Business Administration’s HUBZone Program. Gaines got the job.
Since then, she has supported four programs and two institutional organizations, getting to know several agency leaders quite well. Gaines said she paid attention to little details – like which managers preferred printed materials over presentations, how they organized their offices, and when they typically stopped for coffee or something to eat – and worked to stay one step ahead of them. She recalled one occasion when she realized a manager had not taken a break in five hours and brought her something to drink. “It’s about taking care of the people who are doing the mission. If you don’t take care of yourself, you can’t complete the mission,” she said.
Rick Pettis, the administrative officer for the Center Operations Directorate, appreciates being part of a great team. Pettis has worked at Johnson since 2014, when he retired from the U.S. Navy after 23 years. “I enjoy helping people with problem solving,” he said. “Every day there will be someone who calls me to ask, ‘How do I get this done?’”

He was so nice – he shook my hand and took the time to talk to me.”
Workman has been a civil servant for 52 years and 29 of those have been spent at Johnson. “My career has taken me all over the United States and Germany,” she said. “When my son was in the military and stationed at Ft. Sam Houston in San Antonio he said, ‘Mom, why don’t you move to Texas?’ I didn’t have a good reason to say no, so here I am!”

Outside of meeting and interacting with astronauts, Workman said being able to share NASA with her family and friends is her favorite part of working at Johnson. “It is always exciting to see their reaction,” she said.
Burnett is thankful for a united team that understands the value of their work. “I’m grateful to work with a group of professionals who know the significance of propelling today’s men and women into the next generation of deep space for years to come,” she said. “We are Artemis proud!”
