NASA astronaut Victor Glover tests collection methods for ISS External Microorganisms in the Neutral Buoyancy Lab at Johnson Space Center.NASA Astronauts are scheduled to venture outside the International Space Station to collect microbiological samples during crew spacewalks for the ISS External Microorganisms experiment. This investigation focuses on sampling at sites near life support system vents to examine whether the spacecraft releases microorganisms, how many, and how far they may travel.
This experiment could help researchers understand whether and how these microorganisms survive and reproduce in the harsh space environment and how they may perform at planetary destinations such as the Moon and Mars. Extremophiles, or microorganisms that can survive harsh environments, are also of interest to industries on Earth such as pharmaceuticals and agriculture.
Spacecrafts and spacesuits are thoroughly sterilized before missions; however, humans carry their own microbiomes and continuously regenerate microbial communities. It’s important to understand and address how well current designs and processes prevent or limit the spread of human contamination. The data could help determine whether changes are needed to crewed spacecraft, including spacesuits, that are used to explore destinations where life may exist now or in the past.

Astronaut Set to Patch NASA’s X-ray Telescope Aboard Space Station
NASA astronaut Nick Hague will install patches to the agency’s NICER (Neutron star Interior Composition Explorer) X-ray telescope on the International Space Station as part of a spacewalk scheduled for Jan. 16. Hague, along with astronaut Suni Williams, will also complete other tasks during the outing.
NICER will be the first NASA observatory repaired on-orbit since the last servicing mission for the Hubble Space Telescope in 2009.
Hague and other astronauts, including Don Pettit, who is also currently on the space station, rehearsed the NICER patch procedures in the NBL (Neutral Buoyancy Laboratory), a 6.2-million-gallon indoor pool at NASA’s Johnson Space Center in Houston, in 2024.
NASA astronaut Nick Hague holds a patch for NICER (Neutron star Interior Composition Explorer) at the end of a T-handle tool during a training exercise on May 16, 2024, in the NBL (Neutral Buoyancy Laboratory) at NASA’s Johnson Space Center in Houston. NASA/NBL Dive Team Astronaut Nick Hague removes a patch from the caddy using a T-handle tool during a training exercise in the NBL at NASA Johnson on May 16, 2024. The booklet on his wrist has a schematic of the NICER telescope and where the patches will go.NASA/NBL Dive Team “We use the NBL to mimic, as much as possible, the conditions astronauts will experience while preforming a task during a spacewalk,” said Lucas Widner, a flight controller at KBR and NASA Johnson who ran the NICER NBL sessions. “Most projects outside the station focus on maintenance and upgrades to components like solar panels. It’s been exciting for all of us to be part of getting a science mission back to normal operations.”
From its perch near the space station’s starboard solar array, NICER studies the X-ray sky, including erupting galaxies, black holes, superdense stellar remnants called neutron stars, and even comets in our solar system.
But in May 2023, NICER developed a “light leak.” Sunlight began entering the telescope through several small, damaged areas in the telescope’s thin thermal shields. During the station’s daytime, the light reaches the X-ray detectors, saturating sensors and interfering with NICER’s measurements of cosmic objects. The mission team altered their daytime observing strategy to mitigate the effect.
UAE (United Arab Emirates) astronaut Sultan Alneyadi captured this view of NICER from a window in the space station’s Poisk Mini-Research Module 2 in July 2023. Photos like this one helped the NICER team map the damage to the telescope’s thermal shields.NASA/Sultan Alneyadi Some of NICER’s damaged thermal shields (circled) are visible in this photograph.NASA/Sultan Alneyadi The team also developed a plan to cover the largest areas of damage using wedge-shaped patches. Hague will slide the patches into the telescope’s sunshades and lock them into place.
“We designed the patches so they could be installed either robotically or by an astronaut,” said Steve Kenyon, NICER’s mechanical engineering lead at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “They’re installed using a tool called a T-handle that the astronauts are already familiar with.”
The NBL contains life-size mockups of sections of the space station. Under the supervision of a swarm of scuba divers, a pair of astronauts rehearse exiting and returning through an airlock, traversing the outside of the station, and completing tasks.
For the NICER repair, the NBL team created a full-scale model of NICER and its surroundings near the starboard solar array. Hague, Pettit, and other astronauts practiced taking the patches out of their caddy, inserting them into the sunshades, locking them into place, and verifying they were secure.
The task took just under an hour each time, which included the time astronauts needed to travel to NICER, set up their tools, survey the telescope for previously undetected damage, complete the repair, and clean up their tools.
Practice runs also provided opportunities for the astronauts to troubleshoot how to position themselves so they could reach NICER without touching it too often and for flight controllers to identify safety concerns around the repair.

Members of the NICER team, including Kenyon and the mission’s principal investigator, Keith Gendreau at NASA Goddard, supported the NBL practice runs. They helped answer questions about the physical aspects of the telescope, as well as science questions from the astronauts and flight controllers. NICER is the leading source of science results on the space station.
“It was awesome to watch the training sessions and be able to debrief with the astronauts afterward,” Gendreau said. “There isn’t usually a lot of crossover between astrophysics science missions and human spaceflight. NICER will be the first X-ray telescope serviced by astronauts. It’s been an exciting experience, and we’re all looking forward to the spacewalk where it will all come together.”
The NICER telescope is an Astrophysics Mission of Opportunity within NASA’s Explorers Program, which provides frequent flight opportunities for world-class scientific investigations from space utilizing innovative, streamlined, and efficient management approaches within the heliophysics and astrophysics science areas. NASA’s Space Technology Mission Directorate supported the SEXTANT component of the mission, demonstrating pulsar-based spacecraft navigation.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
As the program manager for people, culture and equity, “people whisperer” Edward Victor Gonzales helps ensure people’s wellbeing, comfort, and safety.
Name: Edward Victor Gonzales
Title: Program Manager for People, Culture, and Equity
Organization: Heliophysics Division, Science and Exploration Directorate (Code 670)
Eddie Gonzales is the program manager for People, Culture, and Equity for the Heliophysics Division at NASA’s Goddard Space Flight Center in Greenbelt, Md.NASA What do you do and what is most interesting about your role here at Goddard?
As the program manager for people, culture, and equity officer for heliophysics, I am responsible for people’s wellbeing, comfort, and safety. What is most interesting to me is the vast diversity across Goddard.
How did you come to Goddard?
I went to college late in life, but never graduated. After high school, I started at Mount San Antonio Community College in Walnut, California, but had to work full time when my then-girlfriend became pregnant. I started in the mail room of an international law firm, gradually working my way into director of the support staff. I worked there for 15 years, often staying overnight. I could not attend night school and there were no online learning options at the time.
In 2001, Warren Christopher, who was the managing partner at the law firm and later became secretary of state in the Clinton administration, wrote me a recommendation that helped me get a job at NASA’s Jet Propulsion Laboratory in Southern California as a business administrator. Apollo 13 inspired me to want to work for NASA. After obtaining the job at NASA JPL, I took a few classes at Pasadena Community College.
In 2009, I was detailed to NASA Headquarters to work in the Office of STEM Education. After two years, I returned to JPL to work on minority-serving programs.
In 2014, I returned to Headquarters for a fellowship to work in the Minority University Research Educational Programs. After a year and a half, I returned to JPL to manage underserved, underrepresented undergraduate programs.
In 2018, I came to Goddard to do outreach for NASA Goddard’s heliophysics division. Three years later, I became the diversity, equity, inclusion, and accessibility officer for heliophysics and now, my current role as people, culture, and equity officer.
As the people, culture, and equity officer, what are your responsibilities?
First, I observe. There are a lot of cues and things that happen in the world that others, including leadership, can sometimes miss. We need to be conscious of these things. We need to be respectful and kind — always.
When something happens in the world that impacts a colleague, I make sure to check in with them daily. On a broader scale, when something happens in the world that affects a particular culture, I check in with that particular group.
I also go to underserved, underrepresented national conferences across the country. At the American Indian Science and Engineering Society conference, I talked about employment opportunities at NASA. It was important for those students to see someone who looked like them. I am half Native American and half Latinx [a gender-neutral term for those with Latin American heritage].
“I was labeled a troublemaker. Teachers wouldn’t help me. My career counselor said I would do amazing work at a car wash and that’s what I should consider doing and not to continue my education. But I didn’t listen.” — Edward Gonzales, Diversity, Equity, Inclusion, and Accessibility Lead, Goddard Space Flight CenterNASA/Taylor Mickal In August 2024, the NASA administrator appointed you to the NASA Advisory Council. What do your duties there entail?
The council has five committees: aeronautics, human exploration, science, STEM, and technology. I am a member of the science committee. My plan is to discuss the cultural role we all play at NASA.
What skills do you use in speaking with underserved, underrepresented communities?
I test the waters and the temperature of leadership. I am very active with the employees. I have an open-door policy.
In addition, I think I am highly culturally aware overall. At conferences, I try to dress, speak, and act approachably for the students who attend.
Most importantly, my cell phone is never to be seen. When interacting with someone, I am very observant of the other person’s body language overall, which helps me understand the other person better. Sometimes body language rather than words will tell you what you need to hear. My wife calls me a “people whisperer.”
What does cultural awareness mean to you?
Know your audience. I do not think about how I do things: I focus on how the next generation will do things. I try to speak their language. And listen, very important to listen.
Typically, when I go to a national conference, students will approach me with a résumé. But at a Native American national conference, the elders may approach me with a student and a résumé. It is important to address the elder first and ask permission to speak to the student. Also, you would say that the student could bring knowledge learned at Goddard back to their reservation instead of saying that the student could leave their reservation. I also always acknowledge the tribe associated with where I am speaking.
Whenever we send a team to a national conference, we send people who are culturally aware of that particular group’s culture.
I also conduct cultural awareness training at Goddard.
What are your hopes for Godard’s DEIA programs?
I want to continue to create a pipeline of future employees that is more diverse, filled with great ideas and solutions, with a safe and welcoming environment for them.
What advice do you give students?
The path to NASA is not linear. You have to find your path.
Eddie Gonzales looks out for colleagues wellbeing, comfort, and safety within NASA Goddard’s diverse workforce. Courtesy of Eddie Gonzales You’ve mentioned that DEIA is essentially about kindness. How do you define kindness? How do you teach it?
Kindness in my humble opinion is about grace, integrity and understanding. And the willingness to learn about others and their cultures. To agree to disagree and have a polite conversation, to create that understanding.
Teaching starts in the home, bad behavior, lack of understanding and racism are taught traits. We must do better and lead by example. To treat others how we want to be treated.
Who are your mentors?
One is Christopher Gardner, whose life was portrayed in “The Pursuit of Happyness.” I recently brought Christopher Gardner to Goddard to do a keynote speech and he even stayed with me. I met him because I saw his movie, read his book, and contacted him.
I teach this lesson to students: Everyone is interested when you take the time to learn what is important to them. If there is someone you want to meet, network to try to meet them. All you have to do is ask. But first, research them so that you can talk to them about themselves and their work. If they say no, then you can move on to the next person.
Gardner told me to focus on my plan A because plan B is not good. If you know that you have a plan B, then you won’t put everything you have into plan A. Tread forward as if there is nothing that you can fall back on.
Another mentor is José Hernández, the first Hispanic astronaut. I proposed to my wife while staying at his condo. He told me to find my “yes” and to never give up. He applied to the astronaut program 13 times before he was finally selected.
What are the next big things on your bucket list?
I want to see the Northern Lights and continue to travel. I just lost 70 pounds and want to lose 20 more. I gave up meat for about six months and now eat chicken and turkey, but no longer eat red meat. I also exercise and now feel great.
I want to continue to attend concerts around the country.

A 3D simulation showing the evolution of turbulent flows in the upper layers of the Sun. The more saturated and bright reds represent the most vigorous upward or downward twisting motions. Clear areas represent areas where there is only relatively slow up-flows, with very little twisting.NASA/Irina Kitiashvili and Timothy A. Sandstrom NASA supercomputers are shedding light on what causes some of the Sun’s most complex behaviors. Using data from the suite of active Sun-watching spacecraft currently observing the star at the heart of our solar system, researchers can explore solar dynamics like never before.
The animation shows the strength of the turbulent motions of the Sun’s inner layers as materials twist into its atmosphere, resembling a roiling pot of boiling water or a flurry of schooling fish sending material bubbling up to the surface or diving it further down below.
“Our simulations use what we call a realistic approach, which means we include as much as we know to-date about solar plasma to reproduce different phenomena observed with NASA space missions,” said Irina Kitiashvili, a scientist at NASA’s Ames Research Center in California’s Silicon Valley who helped lead the study.
Using modern computational capabilities, the team was able, for the first time to reproduce the fine structures of the subsurface layer observed with NASA’s Solar Dynamics Observatory.
“Right now, we don’t have the computational capabilities to create realistic global models of the entire Sun due to the complexity,” said Kitiashvili. “Therefore, we create models of smaller areas or layers, which can show us structures of the solar surface and atmosphere – like shock waves or tornado-like features measuring only a few miles in size; that’s much finer detail than any one spacecraft can resolve.”
Scientists seek to better understand the Sun and what phenomena drive the patterns of its activity. The connection and interactions between the Sun and Earth drive the seasons, ocean currents, weather, climate, radiation belts, auroras and many other phenomena. Space weather predictions are critical for exploration of space, supporting the spacecraft and astronauts of NASA’s Artemis campaign. Surveying this space environment is a vital part of understanding and mitigating astronaut exposure to space radiation and keeping our spacecraft and instruments safe.
This has been a big year for our special star, studded with events like the annular eclipse, a total eclipse, and the Sun reaching its solar maximum period. In December 2024, NASA’s Parker Solar Probe mission – which is helping researchers to understand space weather right at the source – will make its closest-ever approach to the Sun and beat its own record of being the closest human-made object to reach the Sun.
The Sun keeps surprising us. We are looking forward to seeing what kind of exciting events will be organized by the Sun."
Irina Kitiashvili
NASA Scientist
“The Sun keeps surprising us,” said Kitiashvili. “We are looking forward to seeing what kind of exciting events will be organized by the Sun.”
These simulations were run on the Pleaides supercomputer at the NASA Advanced Supercomputing facility at NASA Ames over several weeks of runtime, generating terabytes of data.
NASA is showcasing 29 of the agency’s computational achievements at SC24, the international supercomputing conference, Nov. 17-22, 2023, in Atlanta, Georgia. For more technical information, visit:
