Unveil how NASA’s Scientific Balloon Program revolutionizes space research with eight daring missions from Fort Sumner, New Mexico. Discover the future of exploration
Introduction
NASA’s Scientific Balloon Program is soaring to new heights, literally and figuratively, as it prepares to launch eight scientific balloons from Fort Sumner, New Mexico. This annual fall campaign is not just a routine event; it’s a pivotal part of NASA’s efforts to push the boundaries of scientific research in astrophysics, heliophysics, and atmospheric studies. These balloon missions are more than just high-altitude adventures—they’re critical components of NASA’s broader mission to understand our universe.
Key Points
As the cornerstone of NASA’s balloon operations, the Fort Sumner campaign is set to support 16 diverse missions over two months, from mid-August to mid-October. These missions range from studying exoplanet atmospheres to testing cutting-edge cooling systems in near-space environments. The variety and ambition of these missions underscore NASA’s commitment to using innovative methods to explore space and Earth science.
Mission Details
One of the standout missions in this year’s campaign is the EXCITE (Exoplanet Climate Infrared Telescope) mission, led by Peter Nagler from NASA’s Goddard Space Flight Center. EXCITE aims to probe the atmospheric properties of Jupiter-like exoplanets, providing invaluable data for understanding these distant worlds. After a weather delay in 2023, the EXCITE team is eager to launch from Fort Sumner, with plans to conduct a long-duration flight from Antarctica eventually.

How NASA’s Scientific Balloons Work
NASA’s scientific balloons are marvels of engineering, capable of lifting payloads weighing up to 8,000 pounds to the edge of space. These balloons come in two primary types: zero-pressure balloons and super-pressure balloons. Zero-pressure balloons are typically used for shorter flights, where gas escapes through ducts to maintain stability. In contrast, super-pressure balloons, known for their “pumpkin” shape, are sealed, allowing them to maintain altitude for extended periods—sometimes up to 100 days—by minimizing gas loss.
The balloons, made from thin polyethylene film similar to plastic wrap, are inflated with helium gas and can expand to a volume of 40 million cubic feet—enough to fit a football stadium inside. Once launched, they float at altitudes around 120,000 feet, more than twice as high as commercial airliners, carrying instruments that can observe the universe or gather data about Earth’s atmosphere.
Why NASA is Launching 8 Balloons
The eight balloons launching from Fort Sumner are part of a broader strategy to test and refine technologies that will be used in future long-duration flights from polar regions like Antarctica and Sweden. These short, domestic flights provide an ideal proving ground for the more ambitious missions to come. Moreover, the campaign serves as an invaluable training opportunity for students and early-career scientists and engineers, who are involved in many of the payloads and mission designs.
How NASA Makes Balloons for This Mission
Creating a scientific balloon is a complex process that involves meticulous planning and cutting-edge materials. Aerostar, a leader in high-altitude balloon technology, designed and fabricated the balloons. Each balloon is tailored to its specific mission, considering factors like payload weight, desired flight duration, and the mission’s scientific goals. The zero-pressure balloons used in this campaign are particularly suited for short, domestic flights due to their robust design, which allows them to adapt to the thermal changes experienced during the day-night cycle.
Mission Launch Locations
The Fort Sumner launch facility in New Mexico is a critical site for NASA’s balloon missions. Situated at the Fort Sumner Municipal Airport, the facility includes a World War II-era hangar, payload processing facilities, and a launch pad. This site has been a hub for scientific balloon launches for decades, providing a reliable and well-equipped environment for preparing and launching these high-altitude balloons.
In addition to Fort Sumner, NASA conducts balloon launches from several other locations worldwide, including McMurdo Station in Antarctica, Esrange in Sweden, Alice Springs in Australia, and Wanaka in New Zealand. Each area is selected based on mission-specific needs, including flight duration, safety, cost, and the scientific data to be collected.
Conclusion
NASA’s 2024 Scientific Balloon Program is more than a series of launches—it’s a gateway to discoveries about our planet, our solar system, and the universe beyond. With eight balloons set to take to the skies from New Mexico, carrying diverse scientific instruments, this year’s campaign promises to be a milestone in space research. Whether it’s studying distant exoplanets, testing innovative technologies, or training the next generation of scientists, these missions are a testament to NASA’s enduring commitment to exploration and discovery.
