4 min read NASA Scientific Balloons Ready for Flights Over Antarctica A scientific balloon payload is being prepared for launch in McMurdo Station, Antarctica. NASA’s Wallops Flight Facility NASA kicks off its annual Antarctic Long Duration Balloon Campaign around Dec. 1, which includes three scientific balloon flights planned for launch from the long-duration balloon (LDB) Camp near McMurdo Station, Antarctica. NASA’s stadium-sized, zero-pressure balloons will support a total of five missions on the long-duration flights with one mission vying to break NASA’s heavy-lift, long-duration balloon flight record, which stands at 55 days, 1 hour, and 34 minutes. “The annual Antarctic long-duration balloon campaign is the program’s flagship event for long-duration missions,” said Andrew Hamilton, acting chief of NASA’s Balloon Program Office (BPO). “The environment and stratospheric wind conditions provide a unique and valuable opportunity to fly missions in a near-space environment for days or weeks at a time. The BPO team is excited to provide support to all our missions this year.” Headlining this year’s campaign is the Galactic/Extragalactic ULDB Spectroscopic Terahertz Observatory (GUSTO) mission. This Astrophysics mission is managed by NASA’s Explorers Program Office at Goddard Space Flight Center. The mission is led by principal investigator Christopher Walker from the University of Arizona with support from the Johns Hopkins University Applied Physics Laboratory. GUSTO will aim for 55-plus days in flight above the southernmost hemisphere’s skies to map a large part of the Milky Way galaxy, including the galactic center, and the nearby Large Magellanic Cloud. The GUSTO telescope is equipped with very sensitive detectors for carbon, oxygen, and nitrogen emission lines. Measuring these emission lines will give the GUSTO team deep insight into the full lifecycle of the interstellar medium, the cosmic material found between stars. GUSTO’s science observations will be performed from Antarctica to allow for enough observation time aloft, access to astronomical objects, and solar power provided by the austral summer in the polar region. Additional missions set to fly during the Antarctic LDB campaign include: Anti-Electron Sub-Orbital Payload (AESOP-Lite): The mission, led by a team from the University of Delaware and University of California Santa Cruz, will measure cosmic-ray electrons and positrons. These electron measurements will be compared to Voyager I and II, which reached interstellar space and have been measuring cosmic ray electrons since 2012 and 2018, respectively. AESOP-Lite will fly on a 60 million cubic feet balloon, a test flight set to qualify the balloon for reaching altitudes greater than 150,000 feet, which is higher than NASA’s current stratospheric inventory. Long durAtion evalUation solaR hand LAunch (LAURA): This engineering test flight, led by NASA’s Columbia Scientific Balloon Facility, will utilize solar panels to extend the science capability of the hand launch platform from a few days in flight to long-duration flights. Hand-launched balloons are about 40 times smaller in volume than the heavy-lift balloons and have limited time aloft due to the amount and weight of batteries used for powering the science and balloon instruments. Anihala (Antarctic Infrasound Hand Launch): This piggyback payload on the AESOP-Lite launch, a cooperative mission between the Swedish Institute of Space Physics and Sandia National Lab, aims to measure natural background sound in the stratosphere over a continent where human-generated sound is largely absent. Zero-pressure balloons feature open ducts that allow gas to escape and prevent an increase in pressure from inside the balloon. Gas expansion occurs as it heats during the balloon’s rise above Earth’s surface or by temperature increases from a rising Sun. These balloons, which typically have a shorter flight duration due to the loss of gas from the cycle of day to night, can only fly long-duration missions during the constant daylight of summer in polar regions, where the balloon stays in constant sunlight. NASA’s Wallops Flight Facility in Virginia manages the agency’s scientific balloon flight program with 10 to 15 flights each year from launch sites worldwide. Peraton, which operates NASA’s Columbia Scientific Balloon Facility (CSBF) in Texas, provides mission planning, engineering services, and field operations for NASA’s scientific balloon program. The CSBF team has launched more than 1,700 scientific balloons over some 40 years of operations. NASA’s balloons are fabricated by Aerostar.

  Preparations for Next Moonwalk Simulations Underway (and Underwater)
  When most people think of NASA, they picture rockets, astronauts, and the Moon. But behind the scenes, a group of inventors is quietly rewriting the rules of what’s possible — on Earth, in orbit, and beyond. Their groundbreaking inventions eventually become technology available for industry, helping to shape new products and services that improve life around the globe. For their contributions to NASA technology, we welcome four new inductees into the 2024-2025 NASA Inventors Hall of Fame
  
  A robot for space and the workplace
  
  Myron (Ron) Diftler led the team behind Robonaut 2 (R2), a humanoid robot developed with General Motors. The goal was to create a robot that could help humans both in space and on the factory floor. The R2 robot became the first humanoid robot in space aboard the International Space Station, and part of its technology was licensed for use on Earth, leading to a grip-strengthening robotic glove to help humans with strenuous, repetitive tasks. From factories to space exploration, Diftler’s work has real-world impact.
  
  Some of the toughest electronic chips on and off Earth
  
  Technology developed to one day explore the surface of Venus has to be tough enough to survive the planet where temperatures hit 860°F and the atmosphere is akin to battery acid. Philip Neudeck’s silicon carbide integrated circuits don’t just work — they ran for over 60 days in simulated Venus-like conditions. On Earth, these chips can boost efficiency in wireless communication systems, help make drilling for oil safer, and enable more practical electric vehicles.
  From developing harder chip materials to unlocking new planetary missions, Neudeck is proving that the future of electronics isn’t just about speed — it’s about survival.
  
  Hydrogen sensors that could go the distance on other worlds
  
  Gary Hunter helped develop a hydrogen sensor so advanced it’s being considered for a future mission to Titan, Saturn’s icy moon. These and a range of other sensors he’s helped developed have applications that go beyond space exploration, such as factory floors here on Earth.
  With new missions on the horizon and smarter sensors in development, Hunter is still pushing the boundaries of what NASA technology can do. Whether it’s Titan, the surface of Venus, or somewhere we haven’t dreamed of yet, this work could help shape the way to get there.
  
  Advanced materials research to make travel safer
  
  Advanced materials, such as foams and composites, are key to unlocking the next generation of manufacturing. From space exploration to industry, Erik Weiser spent years contributing his expertise to the development of polymers, ceramics, metals, nanomaterials, and more. He is named on more than 20 patents. During this time, he provided his foam expertise to the Space Shuttle Columbia accident investigation, the Shuttle Discovery Return-to-Flight Investigation and numerous teams geared toward improving the safety of the shuttle.
  Today, Weiser serves as director of the Facilities and Real Estate Division at NASA Headquarters, overseeing the foundation of NASA’s missions. Whether it’s advancing research or optimizing real estate across the agency, he’s helping launch the future, one facility at a time.

- NASA Study Reveals Venus Crust Surprise
  By NASA

  NASA Study Reveals Venus Crust Surprise
  This global view of the surface of Venus is centered at 180 degrees east longitude. Magellan synthetic aperture radar mosaics from the first cycle of Magellan mapping are mapped onto a computer-simulated globe to create this image. Data gaps are filled with Pioneer Venus Orbiter data, or a constant mid-range value. Simulated color is used to enhance small-scale structure. The simulated hues are based on color images recorded by the Soviet Venera 13 and 14 spacecraft. NASA/JPL-Caltech New details about the crust on Venus include some surprises about the geology of Earth’s hotter twin, according to new NASA-funded research that describes movements of the planet’s crust.
  Scientists expected the outermost layer of Venus’ crust would grow thicker and thicker over time given its apparent lack of forces that would drive the crust back into the planet’s interior. But the paper, published in Nature Communications, proposes a crust metamorphism process based on rock density and melting cycles.
  Earth’s rocky crust is made up of massive plates that slowly move, forming folds and faults in a process known as plate tectonics. For example, when two plates collide, the lighter plate slides on top of the denser one, forcing it downward into the layer beneath it, the mantle. This process, known as subduction, helps control the thickness of Earth’s crust. The rocks making up the bottom plate experience changes caused by increasing temperature and pressure as it sinks deeper into the interior of the planet. Those changes are known as metamorphism, which is one cause of volcanic activity.
  In contrast, Venus has a crust that is all one piece, with no evidence for subduction caused by plate tectonics like on Earth, explained Justin Filiberto, deputy chief of NASA’s Astromaterials Research and Exploration Science Division at NASA’s Johnson Space Center in Houston and a co-author on the paper. The paper used modeling to determine that its crust is about 25 miles (40 kilometers) thick on average and at most 40 miles (65 kilometers) thick.
  “That is surprisingly thin, given conditions on the planet,” said Filiberto. “It turns out that, according to our models, as the crust grows thicker, the bottom of it becomes so dense that it either breaks off and becomes part of the mantle or gets hot enough to melt.” So, while Venus has no moving plates, its crust does experience metamorphism. This finding is an important step toward understanding geological processes and evolution of the planet.
  “This breaking off or melting can put water and elements back into the planet’s interior and help drive volcanic activity,” added Filiberto. “This gives us a new model for how material returns to the interior of the planet and another way to make lava and spur volcanic eruptions. It resets the playing field for how the geology, crust, and atmosphere on Venus work together.”
  The next step, he added, is to gather direct data about Venus’ crust to test and refine these models. Several upcoming missions, including NASA’s DAVINCI (Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging) and VERITAS (Venus Emissivity, Radio Science, InSAR, Topography, and Spectroscopy) and, in partnership with ESA (European Space Agency), Envision, aim to study the planet’s surface and atmosphere in greater detail. These efforts could help confirm whether processes like metamorphism and recycling are actively shaping the Venusian crust today—and reveal how such activity may be tied to volcanic and atmospheric evolution.
  “We don’t actually know how much volcanic activity is on Venus,” Filiberto said. “We assume there is a lot, and research says there should be, but we’d need more data to know for sure.”
