Linda Spuler, emergency manager at NASA’s Johnson Space Center in Houston, believes that everyone has a story. “Our stories highlight what we have in common, but they also make us each unique,” she said.
Spuler has worked at Johnson for over 32 years, spending most of her career in Center Operations. Her story has involved helping to coordinate emergency response teams at Johnson in preparation for natural disasters. “Since Johnson is situated on the coast, a good portion of my job revolves around planning for hurricanes,” she said.
Spuler has dealt with natural disasters at Johnson from Tropical Storm Allison in 2001 to Hurricane Beryl in 2024, but none had a greater personal impact than Hurricane Ike, which wrought havoc in Texas in September 2008. “Participating in the response to Hurricane Ike was a proud moment for me,” she said. “We worked from sunup to sundown restoring the center. Civil servants and contractors from various organizations came together, and for those two weeks, our differences didn’t matter.”

Spuler’s journey at NASA began as a dream not originally her own. Her path was shaped by the aspirations of her mother, who was born on an Ojibwe (Chippewa) reservation in Ashland, Wisconsin.
“Although my grandmother lived in Chicago, she returned to the reservation to have her children. My mom is still a voting member of the Bad River Tribe,” said Spuler.
“My mom was studying aerospace engineering at the University of Chicago when she met my dad, a fun-loving electrical engineering major who traced his lineage back to Davy Crockett on his father’s side and Ireland on his mother’s,” said Spuler. “She chose to abandon aerospace to marry my dad, whose degree and love for space brought him to work at Johnson.”
Linda Spuler accepts the Thirty-Year Service Award from Johnson Director Vanessa Wyche to commemorate her service at NASA. NASA/David DeHoyos Spuler said her mother was very proud that her father worked for NASA. “She was very happy when I chose to work here, too,” she said. “She taught me the value and reward of working hard. My mom is proud of her heritage but she is cautious of sharing her story.”

She also represents her culture and pride through her work, honoring the legacy of those who came before her and sharing the story of her mother, her father, and now herself.
Linda Spuler receives the 2019 Furlough Heroes Awards alongside her son, Logan. NASA/James Blair “I celebrate the unique story that makes me part Ojibwe, part Polish, part Texas revolutionary, part Irish, part English, and all me,” she said.

Sols 4362-4363: Plates and Polygons
NASA’s Mars rover Curiosity acquired this image using its Mars Hand Lens Imager (MAHLI) on Nov. 11, 2024 – sol 4360, or Martian day 4,360 of the Mars Science Laboratory Mission – at 00:06:13 UTC. NASA/JPL-Caltech/MSSS Earth planning date: Monday, Nov. 11, 2024
After a successful 23-meter (about 75 feet) drive today in pre-planning we found ourselves in front of some rocks with a curious dark, platy topping. This is similar to material we have seen previously including over the weekend where MAHLI imaged “Buttress Tree.” This beautiful hand-lens image is shown above, where you can see this more resistant platy texture at the top of the layered rock. Unfortunately it was deemed too unsafe to move the arm today, so no contact science observations were made on this dark material, but a plethora of remote science made up for it!
A curious curved fracture along a rock in the workspace became the target of our ChemCam LIBS laser shots called “Pioneer Basin.” ChemCam will then take a long-distance RMI looking back at Gediz Vallis channel, which we have been driving away from. Mastcam is focusing on taking two mosaics of areas of rocks that exhibit light- and dark-toned bands from orbit. We previously drove across these bands in January before we crossed the Gediz Vallis channel. Now that we are over the channel, we are about to drive on the dark, banded material once again. Mastcam is also imaging some interesting polygonal textures we see in a few rocks around the rover. To keep it simple, the science team named all four targets of polygonal rocks “Acrodectes Peak.”
As Curiosity drives further away from the Gediz Vallis channel, the exploration of the sulfate unit continues. Although the driving is tough at times, the beautiful discoveries and amazing geology make the tough times worth it. Let’s hope we can get some contact science activities safe and sound in the next plan.

Bone cellsNASA Malcolm O’Malley and his mom sat nervously in the doctor’s office awaiting the results of his bloodwork. This was no ordinary check-up. In fact, this appointment was more urgent and important than the SATs the seventeen-year-old, college hopeful had spent months preparing for and was now missing in order to understand his symptoms.
But when the doctor shared the results – he had off-the-charts levels of antibodies making him deathly allergic to shellfish – O’Malley realized he had more questions than answers. Like: Why is my immune system doing this? How is it working? Why is it reacting so severely and so suddenly (he’d enjoyed shrimp less than a year ago)? And why does the only treatment – an injection of epinephrine – have nothing to do with the immune system, when allergies appear to be an immune system problem? Years later, O’Malley would look to answer some of these questions while interning in the Space Biosciences Research Branch at NASA’s Ames Research Center in California’s Silicon Valley.
“Anaphylaxis is super deadly and the only treatment for it is epinephrine; and I remember thinking, ‘how is this the best we have?’ because epinephrine does not actually treat the immune system at all – it’s just adrenaline,” said O’Malley, who recently returned to his studies as a Ph.D. student of Biomedical Engineering at the University of Virginia (UVA) in Charlottesville. “And there’s a thousand side effects, like heart attacks and stroke – I remember thinking ‘these are worse than the allergy!’”
O’Malley’s curiosity and desire to better understand the mechanisms and connections between what triggers different immune system reactions combined with his interest in integrating datasets into biological insights inspired him to shift his major from computer science to biomedical engineering as an undergraduate student. With his recent allergy diagnosis and a lifelong connection to his aunt who worked at the UVA Heart and Vascular Center, O’Malley began to build a bridge between the immune system and heart health. By the time he was a senior in college, he had joined the Cardiac Systems Biology Lab, and had chosen to focus his capstone project on better understanding the role of neutrophils, a specific type of immune cell making up 50 to 70% of the immune system, that are involved in cardiac inflammation in high blood pressure and after heart attacks.
jsc2022e083018 (10/26/2022) — A preflight image of beating cardiac spheroid composed of iPSC-derived cardiomyocytes (CMs), endothelial cells (ECs), and cardiac fibroblasts (CFs). These cells are incubated and put under the microscope in space as part of the Effect of Microgravity on Drug Responses Using Heart Organoids (Cardinal Heart 2.0) investigation. Image courtesy of Drs. Joseph Wu, Dilip Thomas and Xu Cao, Stanford Cardiovascular Institute “The immune system is involved in everything,” O’Malley says. “Anytime there’s an injury – a paper cut, a heart attack, you’re sick – the immune system is going to be the first to respond; and neutrophils are the first responders.”
O’Malley’s work to determine what regulates the immune system’s interrelated responses – like how one cell could affect other cells or immune processes downstream – provided a unique opportunity for him to support multiple interdisciplinary NASA biological and physical sciences research projects during his 10-week internship at NASA Ames over the summer of 2024. O’Malley applied machine learning techniques to the large datasets the researchers were using from experiments and specimens collected over many years to help identify possible causes of inflammation seen in the heart, brain, and blood, as well as changes seen in bones, metabolism, the immune system, and more when humans or other model organisms are exposed to decreased gravity, social isolation, and increased radiation. These areas are of keen interest to NASA due to the risks to human health inherent in space exploration and the agency’s plans to send humans on long-duration missions to the Moon, Mars, and beyond.
“It’s exciting that we just never know what’s going to happen, how the immune system is going to react until it’s already been activated or challenged in some way,” said O’Malley. “I’m particularly interested in the adaptive immune system because it’s always evolving to meet new challenges; whether it’s a pandemic-level virus, bacteria or something on a mission to Mars, our bodies are going to have some kind of adaptive immune response.”
During his NASA internship, O’Malley applied a statistical analysis techniques to plot and make more sense of the massive amounts of life sciences data. From there, researchers could find out which proteins, out of hundreds, or attributes – like differences in sex – are related to which behaviors or outcomes. For example, through O’Malley’s analysis, researchers were able to better pinpoint the proteins involved in inflammation of the brain that may play a protective role in spatial memory and motor control during and after exposure to radiation – and how we might be able to prevent or mitigate those impacts during future space missions and even here on Earth.
As someone who’s both black and white, representation is important to me. It’s inspiring to think there will be people like me on the Moon – and that I’m playing a role in making this happen
Malcolm o'malley
Former NASA Intern
“I had this moment where I realized that since my internship supports NASA’s Human Research Program that means the work I’m doing directly applies to Artemis, which is sending the first woman and person of color to the Moon,” reflected O’Malley. “As someone who’s both black and white, representation is important to me. It’s inspiring to think there will be people like me on the Moon – and that I’m playing a role in making this happen.”
Artist conception of a future Artemis Base Camp on the lunar surface NASA When O’Malley wasn’t exploring the mysteries of the immune system for the benefit of all at NASA Ames, he taught himself how to ride a bike and started to surf in the nearby waters of the Pacific Ocean. O’Malley considers Palmyra, Virginia, his hometown and he enjoys playing sports – especially volleyball, water polo, and tennis – reading science fiction and giving guest lectures to local high school students hoping to spark their curiosity.
O’Malley’s vision for the future of biomedical engineering reflects his passion for innovation. “I believe that by harnessing the unique immune properties of other species, we can achieve groundbreaking advancements in limb regeneration, revolutionize cancer therapy, and develop potent antimicrobials that are considered science fiction today,” he said.

The fifth anniversary of the first all-female spacewalk by NASA astronauts Christina H. Koch and Jessica U. Meir seems like a good time to tell the story of women spacewalkers. Since the first woman stepped outside a spacecraft in 1984, 23 women from four nationalities have participated in 61 spacewalks. These women made significant contributions to their national and international programs, conducting pioneering work during their spacewalks. Their accomplishments include servicing of satellites, assembly and maintenance of space stations, conducting research, and testing new spacesuits. Since the first spacewalk performed by a woman in 1984, women have displayed their contributions in performing extravehicular activities and there has even been four all women spacewalks since then.
Table listing women with spacewalk experience.
As of Oct. 18, 2024, 79 women have flown in space, and 23 of them have donned spacesuits of different designs and stepped outside the relative comfort of their spacecraft to work in the harsh environment of open space. The various spacesuits, Russian Orlan, American Extravehicular Mobility Unit, Chinese Feitian-2, and SpaceX’s new design, all provide protection from the harsh environment, essentially turning the astronauts into individual spaceships. They all provide the crew members with the ability to carry out complicated tasks in open space.

Soviet cosmonaut Svetlana Y. Savitskaya made history on July 17, 1984, as the first woman to make a second trip into space, on her second visit to the Salyut 7 space station. Savitskaya made history again on July 25 as the first woman to participate in a spacewalk. During the 3-hour 35-minute excursion, Savitskaya tested a multipurpose tool for electron beam cutting, welding, soldering, and brazing.
Less than three months later, on Oct. 11, NASA astronaut Kathryn D. Sullivan completed the first spacewalk by an American woman from space shuttle Challenger during the STS-41G mission. Sullivan helped test the in-orbit transfer of hydrazine using the Orbital Refueling System. With Sally K. Ride as one of Sullivan’s crewmates, the flight marked the first time a space crew included two women.
NASA astronaut Kathryn C. Thornton completed her first spacewalk in 1992 during STS-49, the second American woman to walk in space. During this excursion, Thornton tested assembly techniques for the future space station. Thornton earned the recognition as the first woman to make more than one spacewalk when she completed two spacewalks on STS-61, the first mission to service the Hubble Space Telescope.

Jernigan, the first woman to perform a spacewalk at the International Space Station during STS-96. Middle right: Expedition 2 NASA astronaut Susan J. Helms, the first female long-duration crew member to conduct a spacewalk during the STS-102 docked phase. Right: Godwin during STS-108, the first woman to complete spacewalks at Mir and the space station.
NASA astronaut Linda M. Godwin has the distinction as the first woman of any nationality to conduct a spacewalk at Mir. As a member of the STS-76 crew, on March 27, 1996, she took part in a 6-hour 2-minute spacewalk to install handrails and four space exposure experiments onto Mir’s Docking Module. Godwin returned to space on STS-108, and on Dec. 10, 2001, took part in a spacewalk lasting 4 hours 12 minutes to install insulation blankets on the space station, earning the title as the first woman to conduct spacewalks at both Mir and the space station.
NASA astronaut Tamara E. Jernigan conducted the first spacewalk by a woman at the embryonic International Space Station. On May 29, 1999, during STS-96, the second space station assembly flight, Jernigan participated in a 7-hour 55-minute spacewalk to install U.S. and Russian cargo cranes, foot restraints, and tool bags.
Expedition 2 NASA astronaut Susan J. Helms performed a spacewalk on March 11, 2001, during the STS-102 docked phase to relocate the Pressurized Mating Adaptor-3 (PMA-3) from Node 1’s nadir port to a berth on its port side, to enable the berthing of the Leonardo Multi-Purpose Logistics Module. This marked the first time a woman long-duration crew member performed a spacewalk. Its 8-hour 56-minute duration makes it the longest spacewalk in history.

As an Expedition 5 flight engineer, NASA astronaut Peggy A. Whitson participated in her first spacewalk on Aug. 16, 2002. Clad in an Orlan spacesuit and using the Pirs module airlock, she assisted in the installation of six debris shield panels on the Zvezda Service Module. Whitson completed her next five spacewalks, wearing Extravehicular Mobility Units and using the Quest airlock, as commander of Expedition 16, one of the busiest assembly and reconfiguration periods at the space station. The primary objectives for the first three of these spacewalks, conducted on Nov. 9, Nov. 20, and Nov. 24, involved relocating the Harmony Node 2 module and PMA-2 to the front of Destiny and preparing Harmony for the arrival of the Columbus module. Work during the fourth and fifth excursions on Dec. 18 and Jan. 30, 2008, had Whitson conduct inspections and maintenance on the station’s solar array joints. During her next mission to the space station, a 289-day stay that set a new record as the longest single flight by a woman, she completed a further four spacewalks. During Expedition 50, on Jan. 6, 2017, she upgraded the station’s power system by installing three new lithium-ion batteries, and on March 30 installed electrical connections to the PMA-3 recently relocated to Harmony’s top-facing port.
During Expedition 51, as station commander once again, Whitson stepped outside on May 12 to replace an avionics package on an external logistics carrier and installed a protective shield on PMA-3. Her 10th and final excursion involved a contingency spacewalk to replace a backup data converter unit that failed three days earlier. With her 10 excursions, Whitson shares a seven-way second place tie for most spacewalks; only one person has conducted more. And with regard to total spacewalk time, she places sixth overall, having spent a total of 60 hours, 21 minutes outside the station.

Williams after the conclusion of the first of her seven career spacewalks. Right: Expedition 20 NASA astronaut Nicole P. Stott during her STS-128 spacewalk.
During STS-115, NASA astronaut Heidemarie M. Stefanyshyn-Piper participated in two of the mission’s three spacewalks. The primary tasks of the excursions on Sept. 12 and 15, 2006, involved the addition of the P3/P4 truss segment including a pair of solar arrays to the station. During her second visit to the space station on STS-126, Stefanyshyn-Piper completed three more spacewalks on Nov. 18, 20, and 22, 2008. Tasks accomplished during these excursions included performing maintenance on one of the solar array joints, replacing a nitrogen tank, and relocating two equipment carts.
During Expedition 14, NASA astronaut Sunita L. Williams completed four spacewalks. During the first excursion during the STS-116 docked phase on Dec. 16, 2006, the primary task involved the reconfiguration of the station’s power system. The primary tasks for Williams’ three Expedition 14 spacewalks on Jan. 31, Feb. 4, and Feb. 8, 2007, involved completing the reconfiguration of the station’s cooling system. As a flight engineer during Expedition 32, Williams conducted spacewalks on Aug. 30, 2012, to replace a faulty power routing unit and prepare the station for the arrival of the Nauka module, and on Sept. 5, 2012, to install a spare power unit. During Expedition 33, Williams assumed command of the station, only the second woman to do so, and during a spacewalk on Nov. 1, 2012, repaired an ammonia leak. Across her seven spacewalks, Williams spent 50 hours 40 minutes outside the station.
Expedition 20 NASA astronaut Nicole P. Stott completed her one and only spacewalk on Sept. 1, 2009, during the STS-128 docked phase. The objectives of the 6-hour 35-minute excursion involved preparing for the replacement of an empty ammonia tank and retrieving American and European experiments from the Columbus module.

Rubins takes the first of her four career spacewalks. Right: Expedition 59 NASA astronaut Anne C. McClain on the first of her two spacewalks.
On July 24, 2010, during Expedition 24, one of the station’s ammonia pump modules failed. The loss of coolant forced controllers to shut down several critical station systems although neither the vehicle nor the crew were ever in danger. The failure resulted in two of the Expedition crew members including NASA astronaut Tracy C. Dyson performing three contingency spacewalks on Aug. 7, 11, and 16, 2010, to replace the pump module. The repairs took nearly 23 hours of spacewalking time. During her next mission, Expedition 71, Dyson began a spacewalk on June 24, 2024, but a leak in her suit forced the cancellation of the excursion after 31 minutes.
NASA astronaut Kathleen H. Rubins completed two spacewalks during Expedition 48. During the first, on Aug. 19, 2016, she helped to install the first of two international docking adapters (IDA) to PMA-2 located at the forward end of Harmony. The IDA allows commercial spacecraft to dock autonomously to the space station. During the second excursion on Sept. 1, she retracted a thermal radiator, tightened struts on a solar array joint, and installed high-definition cameras on the outside of the station. Rubins conducted two more spacewalks during her second mission, Expedition 64. On Feb. 28, 2021, she began to assemble and install modification kits for upcoming solar array upgrades, completing the tasks during the next spacewalk on March 5.
During her first spacewalk on March 22, 2019, Expedition 59 NASA astronaut Anne C. McClain replaced older nickel hydrogen batteries with newer and more efficient lithium-ion batteries. McClain ventured out for her second spacewalk on April 8 to install a redundant power circuit for the station’s Canadarm robotic arm and cables for more expansive wireless coverage outside the station.
Left: Expedition 59 NASA astronaut Christina H. Koch during the first of her six career spacewalks. Right: NASA astronauts Jessica U. Meir, left, and Koch, assisted by their Expedition 61 crewmates, prepare for the first all-woman spacewalk.
During Expedition 59, Koch conducted her first spacewalk on March 29. She helped to install three newer lithium-ion batteries to replace six older nickel hydrogen batteries. The Expedition 61 crew conducted a record nine spacewalks between October 2019 and January 2020, and women participated in five of them. Koch’s second and third spacewalks on Oct 6 and 11 continued the work of replacing the station’s batteries.
Koch and fellow NASA astronaut Jessica U. Meir made history on Oct. 18 when they floated outside the space station to carry out the first all-woman spacewalk, one of several excursions to replace the station’s batteries. The capsule communicator (capcom), the person in the Mission Control Center at NASA’s Johnson Space Center in Houston who communicates with the astronauts in space, for this historic spacewalk was three-time space shuttle veteran Stephanie D. Wilson.
“As much as it’s worth celebrating the first spacewalk with an all-female team, I think many of us are looking forward to it just being normal,” astronaut Dyson said during live coverage of the spacewalk.
Koch and Meir conducted two more all-woman spacewalks on Jan. 15 and 20, 2020, continuing the battery replacement tasks. During her six spacewalks, Koch spent 44 hours 15 minutes outside. In addition to her spacewalk accomplishments, Koch set a new record of 328 days for a single spaceflight by a woman.

During her second trip into space, People’s Republic of China astronaut Wang Yaping launched aboard the Shenzhou 13 spacecraft as part of the second resident crew to live aboard China’s Tiangong space station. On Nov. 7, 2021, she stepped outside the space station, the first Chinese woman to do so, wearing a Feitian-2 spacesuit. She spent 6 hours 25 minutes installing a grapple fixture for the facility’s robotic arm.
During Expedition 66, NASA astronaut Kayla S. Barron completed two spacewalks. During the first one, on Dec. 2, 2021, Barron replaced a faulty communications antenna. On March 15, 2022, during the second spacewalk, she assembled and installed modification kits required for future solar array upgrades.
Italian astronaut Samantha Cristoforetti conducted the first spacewalk by a female European Space Agency astronaut. For the excursion on July 21, 2022, she wore an Orlan spacesuit and used the Poisk module airlock. Objectives of the spacewalk included deploying 10 nanosatellites, working to install the European robotic arm on the Nauka module, and reconfiguring cargo booms.
