The book cover for the 2025 edition of the Microgravity Materials Research Researcher’s Guide June 2025 Edition
Most materials are formed from a partially or totally fluid sample, and the transport of heat and mass from the fluid into the solid during solidification inherently influences the formation of the material and its resultant properties. The ISS provides a long-duration microgravity environment for conducting experiments that enables researchers to examine the effects of heat and mass transport on materials processes in the near-absence of gravity-driven forces. The microgravity environment greatly reduces buoyancy-driven convection, hydrostatic pressure, and sedimentation. It can also be advantageous for designing experiments with reduced container interactions. The reduction in these gravity-related sources of heat and mass transport may be taken advantage of to determine how material processes and microstructure formation are affected by gravity-driven and gravity independent sources of heat and mass transfer.
Materials science experiments on the ISS have yielded broad and significant scientific advancements, including contributing to the development of improved mathematical models for predicting material properties during processing on Earth and enabling a better understanding of microstructure formation during solidification towards controlling the material properties of various alloys.
This researcher’s guide provides information on the acceleration environment of the space station and describes facilities available for materials research. Examples of previous microgravity materials research and descriptions of planned research are also provided.

Shape-Shifting Materials are advanced, adaptive materials capable of changing their physical form, embedding sensors and circuits directly into their structure, and even storing energy, all without traditional wiring. Lockheed Martin is at the forefront of developing these futuristic materials, raising questions about the possible extraterrestrial origin of this technology.
In a previous article, we discussed why suppressed exotic technologies are suddenly being disclosed. One company that frequently comes up in this conversation is Lockheed Martin, the American defense and aerospace giant known for pushing the boundaries of aviation and space innovation.
Imagine an aircraft that can grow its own skin, embed sensors into its body, store energy without wires, and even shift its shape mid-flight to adapt to changing conditions. This isn’t science fiction anymore, Lockheed Martin’s cutting-edge research is turning these futuristic concepts into reality.
But where is all this coming from?
The rapid development and creativity behind Lockheed Martin’s projects raise intriguing questions. Whistleblowers like David Grusch have recently alleged that Lockheed Martin has had access to recovered UFO materials for decades. Supporting this, Don Phillips, a former Lockheed engineer, confirmed years ago that exotic materials have been held and studied by the company since at least the 1950s.
This suggests that for over half a century, Lockheed has secretly been engaged in researching and reverse-engineering off-world technologies. It's possible that the breakthroughs we’re seeing today are the result of this hidden legacy. Ben Rich, former head of Lockheed’s Skunk Works division, famously hinted at this when he said, "We now have the technology to take ET home."
One particularly stunning development involves "smart" materials that behave almost like muscles, allowing aircraft structures to morph in real-time. These materials enable a craft to fine-tune its aerodynamics on the fly, adjusting instantly to turbulence, speed shifts, or mission-specific demands.
Lockheed’s innovations go even further. By embedding carbon nanotubes, extremely strong and highly conductive microscopic structure, directly into the material, they have created surfaces that can transfer information and power without traditional wiring. In these next-generation aircraft, the "skin" itself acts as the nervous system, the energy grid, and the sensor network all at once.
You can only imagine the kinds of technologies that have been developed over the years through the reverse engineering of exotic materials and recovered extraterrestrial craft. Yet, governments and space agencies remain tight-lipped about the existence of advanced alien civilizations, who likely introduced these techniques to Earth unintentionally.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
A super pressure balloon with the EUSO-2 payload is prepared for launch from Wānaka, New Zealand, during NASA’s campaign in 2023.NASA/Bill Rodman NASA’s Scientific Balloon Program has returned to Wānaka, New Zealand, for two scheduled flights to test and qualify the agency’s super pressure balloon technology. These stadium-sized, heavy-lift balloons will travel the Southern Hemisphere’s mid-latitudes for planned missions of 100 days or more.
Launch operations are scheduled to begin in late March from Wānaka Airport, NASA’s dedicated launch site for mid-latitude, ultra long-duration balloon missions.
“We are very excited to return to New Zealand for this campaign to officially flight qualify the balloon vehicle for future science investigations,” said Gabriel Garde, chief of NASA’s Balloon Program Office at the agency’s Wallops Flight Facility in Virginia. “Our dedicated team both in the field and at home has spent years in preparation for this opportunity, and it has been through their hard work, fortitude, and passion that we are back and fully ready for the upcoming campaign.”
While the primary flight objective is to test and qualify the super pressure balloon technology, the flights will also host science missions and technology demonstrations. The High-altitude Interferometer Wind Observation (HIWIND), led by High Altitude Observatory, National Center for Atmospheric Research in Boulder, Colorado, will fly as a mission of opportunity on the first flight. The HIWIND payload will measure neutral wind in the part of Earth’s atmosphere called the thermosphere. Understanding these winds will help scientists predict changes in the ionosphere, which can affect communication and navigation systems. The second flight will support several piggyback missions of opportunity, or smaller payloads, including:
Compact Multichannel Imaging Camera (CoMIC), led by University of Massachusetts Lowell, will study and measure how Earth’s atmosphere scatters light at high altitudes and will measure airglow, specifically the red and green emissions. High-altitude Infrasound from Geophysical Sources (HIGS), led by NASA’s Jet Propulsion Laboratory and Sandia National Laboratories, will measure atmospheric pressure to collect signals of geophysical events on Earth such as earthquakes and volcanic eruptions. These signals will help NASA as it develops the ability to measure seismic activity on Venus from high-altitude balloons. Measuring Ocean Acoustics North of Antarctica (MOANA), led by Sandia National Laboratories and Swedish Institute of Space Physics, aims to capture sound waves in Earth’s stratosphere with frequencies below the limit of human hearing. NASA’s Balloon Program Office at the agency’s Wallops Flight Facility is leading two technology demonstrations on the flight. The INterim Dynamics Instrumentation for Gondolas (INDIGO) is a data recorder meant to measure the shock of the gondola during the launch, termination, and landing phases of flight. The Sensor Package for Attitude, Rotation, and Relative Observable Winds – 7 (SPARROW-7), will demonstrate relative wind measurements using an ultrasonic device designed for the balloon float environment that measures wind speed and direction. NASA’s 18.8-million-cubic-foot (532,000-cubic-meter) helium-filled super pressure balloon, when fully inflated, is roughly the size of Forsyth-Barr Stadium in Dunedin, New Zealand, which has a seating capacity of more than 35,000. The balloon will float at an altitude of around 110,000 feet (33.5 kilometers), more than twice the altitude of a commercial airplane. Its flight path is determined by the speed and direction of wind at its float altitude.
The balloon is a closed system design to prevent gas release. It offers greater stability at float altitude with minimum altitude fluctuations during the day to night cycle compared to a zero pressure balloon. This capability will enable future missions to affordably access the near-space environment for long-duration science and technology research from the Southern Hemisphere’s mid-latitudes, including nighttime observations.
The public is encouraged to follow real-time tracking of the balloons’ paths as they circle the globe on the agency’s Columbia Scientific Balloon Facility website. Launch and tracking information will be shared across NASA’s social media platforms and the NASA Wallops blog.
NASA’s return to Wānaka marks the sixth super pressure balloon campaign held in New Zealand since the agency began balloon operations there in 2015. The launches are conducted in collaboration with the Queenstown Airport Corporation, Queenstown Lake District Council, New Zealand Space Agency, and Airways New Zealand.
“We are especially grateful to our local hosts, partners, and collaborators who have been with us from the beginning and are critical to the success of these missions and this campaign,” said Garde.
NASA’s Wallops Flight Facility in Virginia manages the agency’s scientific balloon flight program with 10 to 16 flights each year from launch sites worldwide. Peraton, which operates NASA’s Columbia Scientific Balloon Facility in Palestine, Texas, provides mission planning, sustaining engineering services, and field operations for NASA’s scientific balloon program. The Columbia team has launched more than 1,700 scientific balloons over some 40 years of operations. NASA’s balloons are fabricated by Aerostar. The NASA Scientific Balloon Program is funded by the NASA Headquarters Science Mission Directorate Astrophysics Division.

Artist’s rendering of a potentially habitable super-Earth orbiting a star called HD 20794. Illustration credit: Gabriel Pérez Díaz, SMM (IAC) The Discovery
A possible “super-Earth” orbits a relatively close, Sun-like star, and could be a habitable world – but one of extreme temperature swings, from scorching heat to deep freeze.
Key Facts
The newly confirmed planet is the outermost of three detected so far around a star called HD 20794, just 20 light-years from Earth. Its 647-day orbit is comparable to Mars in our solar system. But this planet’s orbit is highly eccentric, stretched into an oval shape. That brings the planet close enough to the star to experience runaway heating for part of its year, then carries it far enough away to freeze any potential water on its surface. The planet has been bouncing between these extremes roughly every 300 days – perhaps for billions of years.
Details
The planet spends a good chunk of its year in the “habitable zone” around its star, the orbital distance that would allow liquid water to form on the surface under the right atmospheric conditions. But because of its eccentric orbit, it moves to a distance interior to the inner edge of the habitable zone when closest to the star, and outside the outer edge when farthest away. At its closest, the planet’s distance from the star is comparable to Venus’s distance from the Sun; at its farthest point, it is nearly twice the distance from Earth to the Sun. The planet is possibly rocky, like Earth, but could be a heftier version – about six times as massive as our home planet.
Star HD 20794 and its posse of possible planets have been extensively studied, but the international team of astronomers that confirmed the outer planet, led by Nicola Nari of Light Bridges S.L. and the Instituto de Astrofisica de Canarias, examined more than 20 years worth of data to pin down all three planets’ orbits and likely masses.
The scientists relied on data from two ground-based, precision instruments: HARPS, the High Accuracy Radial velocity Planet Searcher in La Silla, Chile, and ESPRESSO, the Echelle Spectrograph for Rocky Exoplanets and Stable Spectroscopic Observations in Paranal, Chile. Both instruments, connected to powerful telescopes, measure tiny shifts in the light spectrum of stars, caused by the gravity of planets tugging the star back and forth as they orbit.
But such tiny shifts in the star’s spectrum also can be caused by imposters – spots, flares, or other activity on the star’s surface, carried along as the star rotates and masquerading as orbiting planets. The science team spent years painstakingly analyzing the spectrum shifts, or “radial velocity” data, for any sign of background noise or even jitters from the instruments themselves. They confirmed the reputation of HD 20794 as a fairly quiet star, not prone to outbursts that might be confused for signs of orbiting planets.
Fun Facts
The elliptically orbiting super-Earth appears to be an ideal target for future space-based telescopes designed to search for habitable worlds, seeking possible signs of life. High on the list is NASA’s Habitable Worlds Observatory, which will someday examine the atmospheres of Earth-sized planets around Sun-like stars. When launched in the decades ahead, the observatory would spread the light from such planets into a spectrum to determine which gases are present – including those that might reveal some form of life. The relative closeness of HD 20974, only 20 light-years away, its brightness, and its low level of surface activity – not to mention the third planet’s wild temperature swings – could make this system a prime candidate for scrutiny by HWO.
The Discoverers
The international science team that confirmed the eccentric super-Earth was led by researcher Nicola Nari of the Light Bridges S.L. and the Instituto de Astrofisica de Canarias, and included Dr. Michael Cretignier of the University of Oxford, who first picked up the potential planet’s signal in 2022. Their paper, “Revisiting the multi-planet system of the nearby star HD 20794,” was published online by the journal, Astronomy and Astrophysics, in January 2025.
