Preparations for Next Moonwalk Simulations Underway (and Underwater)
Research into phase-change material (PCM) options for NASA helped one of the researchers find the ideal material to use in a mug that maintains the ideal temperature of a hot beverage for hours. ThermAvant International now offers mugs and tumblers.Credit: ThermAvant International LLC Dr. Hongbin Ma was tired of drinking coffee that had gone cold. Fortunately, Ma, the CEO of ThermAvant Technologies LLC in Columbia, Missouri, was working on a NASA-funded study of phase-change materials, which are used to hold a steady temperature. Materials absorb or release more heat as they transition from solid to liquid or vice versa than they do before or after this phase change.
NASA has long used phase-changing materials to manage temperature extremes in space. The Apollo lunar rover, International Space Station, Orion capsule, and headlights on the newest spacesuit design all utilize phase-change material. As part of his NASA-funded research, Ma tested and recommended a phase-change material that could be used in a spacesuit-cooling system, a modified version of those used in spacecraft.
A phase-change material needs to transition at the desired temperature, but it also needs to be safe. Paraffin wax and refrigerants are effective but are toxic to humans, which would make a leak hazardous. Ma’s team ultimately recommended a bio-based option for spacesuits.
Bio-based waxes also proved to be the perfect solution for maintaining optimal temperature for coffee. In this case, it was a beeswax-like soy substance. Ma’s company, ThermAvant Technologies, took the opportunity to infuse the bio-based waxes into a product on Earth.
A phase-change heat exchanger like this one uses uses a PCM that will help maintain a comfortable temperature in the Orion spacecraft. NASA-funded research into spacesuit material alternatives helped ThermAvant International LLC develop the Burnout thermal mug for coffee. Credit: NASA Released in 2018, the Burnout Mug is vacuum insulated with the wax called HeatZorb, sealed between the inner and outer shells. The wax is formulated to maintain the ideal temperature for hot drinks over time. As soon as hot liquid goes in, the wax absorbs excess heat and melts, resulting in a drinkable temperature in just a few moments. As the coffee starts to cool, that stored heat is released back into it.
The company is developing other uses for the same technology to meet unique needs in the medical field. Two in development are a small insulin container and a donor organ transportation box – both of which rely on specific, controlled temperatures. From hot beverages to life-saving medical equipment, NASA’s research continues to drive innovation across industries.

Pioneer of Change: America Reyes Wang Makes NASA Space Biology More Open
America Reyes Wang, the lead of the the Space Biology Biospecimen Sharing Program at NASA’s Ames Research Center in California’s Silicon Valley, stands beside a spacesuit display. Photo courtesy of America Reyes Wang As humans return to the Moon and push on toward Mars, scientists are ramping up research into the effects of space on the body to make sure astronauts stay healthy on longer missions. This research often involves spaceflight studies of rodents, insects, and other models in orbiting laboratories such as the International Space Station. However, space-related biological samples are difficult to get, meaning that researchers who want to study space biology are frequently out of luck.
America Reyes Wang, a KBR employee and the lead of the Space Biology Biospecimen Sharing Program at NASA’s Ames Research Center in California’s Silicon Valley, oversees the team that has changed that. Birthed from an initiative first pioneered in the 1960s, the Biospecimen Sharing Program collects samples and data from NASA non-human space biology studies and makes them available in the public, open NASA Open Science Data Repository (OSDR).
To derive the most benefit from the precious few biology studies taking place in space, Reyes Wang arranges collaborations on space biology dissections with NASA-funded researchers so that her team can collect and preserve unutilized biospecimens for others to use. Outside researchers can request the samples to study in person by writing and submitting proposals. Once analyzed, researchers share their data back with the NASA OSDR for other investigators to access and study.
The ethos of open science is central to Reyes Wang’s approach to her work. “The samples that we work with are so precious,” she said. “To me, it’s a no-brainer — why not share what we can share?”
America Reyes Wang wears personal protective equipment (PPE) while working on an activity for NASA’s Biospecimen Sharing Program. Photo courtesy of America Reyes Wang Reyes Wang aspired to work in the scientific or medical field from a young age, driven by her desire to help people. Her father, who was born in El Salvador and dreamed of being an astronaut after watching the 1969 Moon landing, inspired Reyes Wang to fall in love with space. She also credited her Salvadoran and Mexican family with teaching her the value of understanding different experiences.
“To me, being Hispanic, especially as a Latina in STEM, means recognizing and building upon the hard work and sacrifices of those who came before me, as well as extending a helping hand to those around me for the betterment of us all,” Reyes Wang said. “It also means enjoying and sharing our vibrant cultures.”
As a student at Stanford University, Reyes Wang conducted neurobiology research with rodents, but assumed she would have to choose her love of biology over her love of space. The field of space biology allowed her to combine those interests. Having quietly dreamed of working for NASA for years, she was also thrilled to find that she could work on NASA missions as a space biologist.
If we want to keep up with the pace of humanity’s aspirations to travel further and for longer … open science is one of the best tools we have for achieving those dreams.
America Reyes Wang
Biospecimen Sharing Program Lead
Reyes Wang first found a role supporting NASA as an experiment support scientist for the agency’s Rodent Research Program. While she no longer facilitates research on the International Space Station in her current position, she uses her scientific expertise and collaborative outlook to guide the Biospecimen Sharing Program in a direction that will most help advance science.
Despite space biology’s status as a relatively niche field, Reyes Wang has noted its tremendous impact on the biological sciences, medicine, and technology as a whole. For example, spaceflown biological samples are often used to investigate diseases that affect people on Earth. Reyes Wang’s involvement in accelerating these studies captures her long-held desire to help people.
“Open science gives the world an opportunity to get these important answers much more quickly,” Reyes Wang said. “If we want to keep up with the pace of humanity’s aspirations to travel further and for longer, we need to pick up the pace when it comes to getting the answers, and I think open science is one of the best tools we have for achieving those dreams.”

NASA’s Hubble Finds that a Black Hole Beam Promotes Stellar Eruptions
This is an artist’s concept looking down into the core of the giant elliptical galaxy M87. A supermassive black hole ejects a 3,000-light-year-long jet of plasma, traveling at nearly the speed of light. In the foreground, to the right is a binary star system. The system is far from the black hole, but in the vicinity of the jet. In the system an aging, swelled-up, normal star spills hydrogen onto a burned-out white dwarf companion star. As the hydrogen accumulates on the surface of the dwarf, it reaches a tipping point where it explodes like a hydrogen bomb. Novae frequently pop-off throughout the giant galaxy of 1 trillion stars, but those near the jet seem to explode more frequently. So far, it’s anybody’s guess why black hole jets enhance the rate of nova eruptions. NASA, ESA, Joseph Olmsted (STScI)

In a surprise finding, astronomers using NASA’s Hubble Space Telescope have discovered that the blowtorch-like jet from a supermassive black hole at the core of a huge galaxy seems to cause stars to erupt along its trajectory. The stars, called novae, are not caught inside the jet, but apparently in a dangerous neighborhood nearby.
The finding is confounding researchers searching for an explanation. “We don’t know what’s going on, but it’s just a very exciting finding,” said lead author Alec Lessing of Stanford University. “This means there’s something missing from our understanding of how black hole jets interact with their surroundings.”
A nova erupts in a double-star system where an aging, swelled-up, normal star spills hydrogen onto a burned-out white dwarf companion star. When the dwarf has tanked up a mile-deep surface layer of hydrogen that layer explodes like a giant nuclear bomb. The white dwarf isn’t destroyed by the nova eruption, which ejects its surface layer and then goes back to siphoning fuel from its companion, and the nova-outburst cycle starts over again.
Hubble found twice as many novae going off near the jet as elsewhere in the giant galaxy during the surveyed time period. The jet is launched by a 6.5-billion-solar-mass central black hole surrounded by a disk of swirling matter. The black hole, engorged with infalling matter, launches a 3,000-light-year-long jet of plasma blazing through space at nearly the speed of light. Anything caught in the energetic beam would be sizzled. But being near its blistering outflow is apparently also risky, according to the new Hubble findings.
A Hubble Space Telescope image of the giant galaxy M87 shows a 3,000-light-year-long jet of plasma blasting from the galaxy’s 6.5-billion-solar-mass central black hole. The blowtorch-like jet seems to cause stars to erupt along its trajectory. These novae are not caught inside the jet, but are apparently in a dangerous neighborhood nearby. During a recent 9-month survey, astronomers using Hubble found twice as many of these novae going off near the jet as elsewhere in the galaxy. The galaxy is the home of several trillion stars and thousands of star-like globular star clusters.

The finding of twice as many novae near the jet implies that there are twice as many nova-forming double-star systems near the jet or that these systems erupt twice as often as similar systems elsewhere in the galaxy.
“There’s something that the jet is doing to the star systems that wander into the surrounding neighborhood. Maybe the jet somehow snowplows hydrogen fuel onto the white dwarfs, causing them to erupt more frequently,” said Lessing. “But it’s not clear that it’s a physical pushing. It could be the effect of the pressure of the light emanating from the jet. When you deliver hydrogen faster, you get eruptions faster. Something might be doubling the mass transfer rate onto the white dwarfs near the jet.” Another idea the researchers considered is that the jet is heating the dwarf’s companion star, causing it to overflow further and dump more hydrogen onto the dwarf. However, the researchers calculated that this heating is not nearly large enough to have this effect.
“We’re not the first people who’ve said that it looks like there’s more activity going on around the M87 jet,” said co-investigator Michael Shara of the American Museum of Natural History in New York City. “But Hubble has shown this enhanced activity with far more examples and statistical significance than we ever had before.”
Shortly after Hubble’s launch in 1990, astronomers used its first-generation Faint Object Camera (FOC) to peer into the center of M87 where the monster black hole lurks. They noted that unusual things were happening around the black hole. Almost every time Hubble looked, astronomers saw bluish “transient events” that could be evidence for novae popping off like camera flashes from nearby paparazzi. But the FOC’s view was so narrow that Hubble astronomers couldn’t look away from the jet to compare with the near-jet region. For over two decades, the results remained mysteriously tantalizing.
Compelling evidence for the jet’s influence on the stars of the host galaxy was collected over a nine-month interval of Hubble observing with newer, wider-view cameras to count the erupting novae. This was a challenge for the telescope’s observing schedule because it required revisiting M87 precisely every five days for another snapshot. Adding up all of the M87 images led to the deepest images of M87 that have ever been taken.
In a surprise finding, astronomers, using NASA’s Hubble Space Telescope have discovered that the jet from a supermassive black hole at the core of M87, a huge galaxy 54 million light years away, seems to cause stars to erupt along its trajectory.
NASA’s Goddard Space Flight Center; Lead Producer: Paul Morris Hubble found 94 novae in the one-third of M87 that its camera can encompass. “The jet was not the only thing that we were looking at — we were looking at the entire inner galaxy. Once you plotted all known novae on top of M87 you didn’t need statistics to convince yourself that there is an excess of novae along the jet. This is not rocket science. We made the discovery simply by looking at the images. And while we were really surprised, our statistical analyses of the data confirmed what we clearly saw,” said Shara.
This accomplishment is entirely due to Hubble’s unique capabilities. Ground-based telescope images do not have the clarity to see novae deep inside M87. They cannot resolve stars or stellar eruptions close to the galaxy’s core because the black hole’s surroundings are far too bright. Only Hubble can detect novae against the bright M87 background.
Novae are remarkably common in the universe. One nova erupts somewhere in M87 every day. But since there are at least 100 billion galaxies throughout the visible universe, around 1 million novae erupt every second somewhere out there.
The Hubble Space Telescope has been operating for over three decades and continues to make ground-breaking discoveries that shape our fundamental understanding of the universe. Hubble is a project of international cooperation between NASA and ESA (European Space Agency). NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the telescope and mission operations. Lockheed Martin Space, based in Denver, Colorado, also supports mission operations at Goddard. The Space Telescope Science Institute in Baltimore, Maryland, which is operated by the Association of Universities for Research in Astronomy, conducts Hubble science operations for NASA.

On Sept. 9 and 10, scientists and engineers tested NASA’s LEMS (Lunar Environment Monitoring Station) instrument suite in a “sandbox” of simulated Moon regolith at the Florida Space Institute’s Exolith Lab at the University of Central Florida in Orlando.
Lunar regolith is a dusty, soil-like material that coats the Moon’s surface, and researchers wanted to observe how the material would interact with LEMS’s hardware, which is being developed to fly to the Moon with Artemis III astronauts in late 2026.
Designed and built at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, LEMS is one of three science payloads chosen for development for Artemis III, which will be the first mission to land astronauts on the lunar surface since 1972.
The LEMS instrument package can operate both day and night. It will carry two University of Arizona-built seismometers to the surface to perform long-term monitoring for moonquakes and meteorite impacts.
