Farah Al Fulfulee was just four years old when she started climbing onto the roof of her family’s house in Iraq to gaze at the stars.
“It scared me how vast and quiet the sky was, but it made me very curious. I grew a deep passion for the stars and constellations and what they might represent,” she said.
Her father noticed her interest and began bringing home books and magazines about space. Al Fulfulee first read about NASA in those pages and was fascinated by the agency’s mission to explore the cosmos for the benefit of all humanity.
“Right then I knew I had to be an astronaut! I must go to space myself and get a closer look,” she said. “I knew I must find a way to go and work for NASA and fulfill my dream, working with other people like me who had a passion to explore the universe.”

Her dedication to schoolwork and excellence in science and math earned her a spot at the University of Baghdad College of Engineering. She completed a degree in electronic and communication engineering — similar to American electrical and computer engineering programs — and graduated as one of the top 10 students in her class. “We had a graduation party where you dress up as what you want to be in the future,” she recalled. “I wore a spacesuit.”

Image courtesy of Farah Al Fulfulee Al Fulfulee was ready to launch her career, but Iraq did not have a developed space industry and finding work as a female engineer was a challenge. She accepted a project engineer position with a prominent Iraqi engineering firm in the information technology sector and spent four years working for the company in Iraq, Turkey, and Jordan, but she was disappointed to discover that her role involved very little engineering. “I was the only female on the team,” she said. “It was not common for a woman to work in the field or with customers, so I was always left behind to do office work. The job was not fulfilling.”
Still determined to join NASA, Al Fulfulee kept looking for her chance to come to the United States and finally found one in 2016, when she moved to Oklahoma to be near her sister. A new challenge soon rose: Without a degree from an American school or previous work experience in the United States, engineering opportunities were hard to come by. Al Fulfulee spent the next six years working in quality assurance for a human resources software company while she completed a MicroMasters program in software verification and management from the University of Maryland and honed her English and leadership skills.
Her big break came in 2022, when she landed a job with Boeing Defense, Space, and Security as a software quality engineer. “I was so excited,” she said. “I knew I was much closer to my dream since Boeing worked in the space industry and I would be able to apply internally to work on a space program.”

Image courtesy of Farah Al Fulfulee Less than one year later, Al Fulfulee became a system design and analysis engineer for the International Space Station Program and joined the Station Management and Control Team at NASA’s Johnson Space Center in Houston. She helps develop requirements, monitors performance, and validates testing for electrical systems and software supporting space station payloads. She also designs hardware, software, and interface specifications for those systems. Al Fulfulee has served as the team’s point of contact, delivering verification assessment and data assessment reports for NASA’s SpaceX Crew-9 and Crew-10 missions, as well as the upcoming Axiom Mission 4 flight. She is currently working to support testing and verification for NASA’s SpaceX Crew-11.
“I could not be happier,” she declared.
She is also not stopping. “I won’t quit until I wear the blue suit.”

She is pursuing a master’s degree in Space Operations Engineering from the University of Colorado, Colorado Springs. She is an avid gardener and learning how to grow produce indoors as a volunteer experimental botanist with the Backyard Produce Project, noting that such knowledge might come in handy on Mars.
She is also helping to inspire the next generation. Earlier this year, Al Fulfulee was a guest speaker at the Women in Tech & Business Summit in Iraq – an event designed to encourage Iraqi women to pursue technology careers. “I was the only person representing women in space,” she said. “It was a really moving experience.” Al Fulfulee provided practical advice on breaking barriers in aerospace and shared her story with the crowd.
“I know my path is long and across the continents,” she said, “but I am enjoying my journey.”

Preparations for Next Moonwalk Simulations Underway (and Underwater)
How do we do research in zero gravity?
Actually when astronauts do experiments on the International Space Station, for instance, to environment on organisms, that environment is actually technically called microgravity. That is, things feel weightless, but we’re still under the influence of Earth’s gravity.
Now, the very microgravity that we’re trying to study up there can make experiments actually really kind of difficult for a bunch of different reasons.
First of all, stuff floats. So losing things in the ISS is a very real possibility. For example,
there was a set of tomatoes that was harvested in 2022 put it in a bag and it floated away and we couldn’t find it for eight months.
So to prevent this kind of thing from happening, we use a lot of different methods, such as using enclosed experiment spaces like glove boxes and glove bags. We use a lot of Velcro to stick stuff to.
Another issue is bubbles in liquids. So, on Earth, bubbles float up, in space they don’t float up, they’ll interfere with optical measurements or stop up your microfluidics. So space experiment equipment often includes contraptions for stopping or blocking or trapping bubbles.
A third issue is convection. So on Earth, gravity drives a process of gas mixing called convection and that helps circulate air. But without that in microgravity we worry about some of our experimental organisms and whether they’re going to get the fresh air that they need. So we might do things like adding a fan to their habitat, or if we can’t, we’ll take their habitat and put it somewhere where there might already be a fan on the ISS or in a corridor where we think they are going to be a lot of astronauts moving around and circulating the air.
Yet another issue is the fact that a lot of the laboratory instruments we use on Earth are not designed for microgravity. So to ensure that gravity doesn’t play a factor in how they work, we might do experiments on the ground where we turn them on their side or upside down, or rotate them on a rotisserie to make sure that they keep working.
So, as you can tell, for every experiment that we do on the International Space Station, there’s a whole team of scientists on the ground that has spent years developing the experiment design. And so I guess the answer to how we do research in microgravity is with a lot of practice and preparation.

Preparations for Next Moonwalk Simulations Underway (and Underwater)

University of Maryland, College Park
The proposed investigation will address key technological challenges associated with a previously funded NIAC Phase I award titled “On-Orbit, Collision-Free Mapping of Small Orbital Debris”. Sub-cm orbital debris in LEO is not detectable or trackable using conventional technologies and poses a major hazard to crewed and un-crewed spacecraft. Orbital debris is a concern to NASA, as well as commercial and DoD satellite providers. In recent years, beginning with our NIAC Phase I award, we have been developing the idea that the sub-cm orbital debris environment may be monitored by detecting the plasma signature of the debris, rather than optical or radar observations of the debris itself. Our prior work has shown that sub-cm orbital debris may produce plasma solitons, which are a type of wave in the ionosphere plasma that do not disperse as readily as traditional waves. Debris may produce solitons that are co-located with the debris (called pinned solitons) or that travel ahead of the debris (called precursor solitons). We have developed computational models to predict the characteristics of the plasma solitons generated by a given piece of debris. These solitons may be detectable by 12U smallsats outfitted with multi-needle Langmuir probes.
In this Phase II NIAC award, we will address two key technical challenges that significantly effect the value of soliton-based debris detection: 1. Develop an algorithm to constrain debris size and speed based on observed soliton characteristics. Our prior investigations have produced predictions of soliton characteristics as a function of debris characteristics. However, the inverse problem is not analytically solvable. We will develop machine learning algorithms to address this challenge. 2. Evaluate the feasibility and value of detecting soliton velocity. Multiple observations of the same soliton may allow us to constrain the distance that the soliton has traveled from the debris. When combined with the other characteristics of the soliton and knowledge of the local plasma environment, back propagation of the soliton in plasma simulations may allow us to extract the position and velocity vectors of the debris. If it is possible to determine debris size, position and velocity from soliton observations, this would provide a breakthrough in space situational awareness for debris that is currently undetectable using conventional technology. However, even if only debris size and speed can be inferred from soliton detections, this technology is still a revolutionary improvement on existing methods of characterizing the debris flux, which provide data only on a multi-year cadence. This proposed investigation will answer key technological questions about how much information can be extracted from observed soliton signals and trade mission architectures for complexity and returned data value. Additionally, we will develop a roadmap to continue to advance this technology.

NASA’s NICER Maps Debris From Recurring Cosmic Crashes
Lee esta nota de prensa en español aquí.
For the first time, astronomers have probed the physical environment of repeating X-ray outbursts near monster black holes thanks to data from NASA’s NICER (Neutron star Interior Composition Explorer) and other missions.
Scientists have only recently encountered this class of X-ray flares, called QPEs, or quasi-periodic eruptions. A system astronomers have nicknamed Ansky is the eighth QPE source discovered, and it produces the most energetic outbursts seen to date. Ansky also sets records in terms of timing and duration, with eruptions every 4.5 days or so that last approximately 1.5 days.
“These QPEs are mysterious and intensely interesting phenomena,” said Joheen Chakraborty, a graduate student at the Massachusetts Institute of Technology in Cambridge. “One of the most intriguing aspects is their quasi-periodic nature. We’re still developing the methodologies and frameworks we need to understand what causes QPEs, and Ansky’s unusual properties are helping us improve those tools.”
Watch how astronomers used data from NASA’s NICER (Neutron star Interior Composition Explorer) to study a mysterious cosmic phenomenon called a quasi-periodic eruption, or QPE.
NASA’s Goddard Space Flight Center Ansky’s name comes from ZTF19acnskyy, the moniker of a visible-light outburst seen in 2019. It was located in a galaxy about 300 million light-years away in the constellation Virgo. This event was the first indication that something unusual might be happening.
A paper about Ansky, led by Chakraborty, was published Tuesday in The Astrophysical Journal.
A leading theory suggests that QPEs occur in systems where a relatively low-mass object passes through the disk of gas surrounding a supermassive black hole that holds hundreds of thousands to billions of times the Sun’s mass.
When the lower-mass object punches through the disk, its passage drives out expanding clouds of hot gas that we observe as QPEs in X-rays.
Scientists think the eruptions’ quasi-periodicity occurs because the smaller object’s orbit is not perfectly circular and spirals toward the black hole over time. Also, the extreme gravity close to the black hole warps the fabric of space-time, altering the object’s orbits so they don’t close on themselves with each cycle. Scientists’ current understanding suggests the eruptions repeat until the disk disappears or the orbiting object disintegrates, which may take up to a few years.
A system astronomers call Ansky, in the galaxy at the center of this image, is home to a recently discovered series of quasi-periodic eruptions. Sloan Digital Sky Survey “Ansky’s extreme properties may be due to the nature of the disk around its supermassive black hole,” said Lorena Hernández-García, an astrophysicist at the Millennium Nucleus on Transversal Research and Technology to Explore Supermassive Black Holes, the Millennium Institute of Astrophysics, and University of Valparaíso in Chile. “In most QPE systems the supermassive black hole likely shreds a passing star, creating a small disk very close to itself. In Ansky’s case, we think the disk is much larger and can involve objects farther away, creating the longer timescales we observe.”
Hernández-García, in addition to being a co-author on Chakraborty’s paper, led the study that discovered Ansky’s QPEs, which was published in April in Nature Astronomy and used data from NICER, NASA’s Neil Gehrels Swift Observatory and Chandra X-ray Observatory, as well as ESA’s (European Space Agency’s) XMM-Newton space telescope.
NICER’s position on the International Space Station allowed it to observe Ansky about 16 times every day from May to July 2024. The frequency of the observations was critical in detecting the X-ray fluctuations that revealed Ansky produces QPEs.
Chakraborty’s team used data from NICER and XMM-Newton to map the rapid evolution of the ejected material driving the observed QPEs in unprecedented detail by studying variations in X-ray intensity during the rise and fall of each eruption.
The researchers found that each impact resulted in about a Jupiter’s worth of mass reaching expansion velocities around 15% of the speed of light.
The NICER (Neutron star Interior Composition Explorer) X-ray telescope is reflected on NASA astronaut and Expedition 72 flight engineer Nick Hague’s spacesuit helmet visor in this high-flying “space-selfie” taken during a spacewalk on Jan. 16, 2025. NASA/Nick Hague The NICER telescope’s ability to frequently observe Ansky from the space station and its unique measurement capabilities also made it possible for the team to measure the size and temperature of the roughly spherical bubble of debris as it expanded.
“All NICER’s Ansky observations used in these papers were collected after the instrument experienced a ‘light leak’ in May 2023,” said Zaven Arzoumanian, the mission’s science lead at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “Even though the leak – which was patched in January – affected the telescope’s observing strategy, NICER was still able to make vital contributions to time domain astronomy, or the study of changes in the cosmos on timescales we can see.”
After the repair, NICER continued observing Ansky to explore how the outbursts have evolved over time. A paper about these results, led by Hernández-García and co-authored by Chakraborty, is under review.
Observational studies of QPEs like Chakraborty’s will also play a key role in preparing the science community for a new era of multimessenger astronomy, which combines measurements using light, elementary particles, and space-time ripples called gravitational waves to better understand objects and events in the universe.
One goal of ESA’s future LISA (Laser Interferometer Space Antenna) mission, in which NASA is a partner, is to study extreme mass-ratio inspirals — or systems where a low-mass object orbits a much more massive one, like Ansky. These systems should emit gravitational waves that are not observable with current facilities. Electromagnetic studies of QPEs will help improve models of those systems ahead of LISA’s anticipated launch in the mid-2030s.
“We’re going to keep observing Ansky for as long as we can,” Chakraborty said. “We’re still in the infancy of understanding QPEs. It’s such an exciting time because there’s so much to learn.”
