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.

NASA/Sara Lowthian-Hanna The phases of the lunar eclipse are visible in this time-lapse image of the Moon above the Space Environments Complex at NASA’s Neil Armstrong Test Facility in Sandusky, OH on March 14, 2025.
Toward the middle of the Moon’s track through the sky, it appears red – this is the Blood Moon. One meaning of a “Blood Moon” is based on its red glow. This blood moon occurs during a total lunar eclipse. During a total lunar eclipse, Earth lines up between the Moon and the Sun, hiding the Moon from sunlight. When this happens, the only light that reaches the Moon’s surface is from the edges of the Earth’s atmosphere. The air molecules from Earth’s atmosphere scatter out most of the blue light. The remaining light reflects onto the Moon’s surface with a red glow, making the Moon appear red in the night sky.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
The space shuttle Endeavour is seen on launch pad 39a as a storm passes by prior to the rollback of the Rotating Service Structure (RSS), Thursday, April 28, 2011, at Kennedy Space Center in Cape Canaveral, Fla. During the 14-day mission, Endeavour and the STS-134 crew will deliver the Alpha Magnetic Spectrometer (AMS) and spare parts including two S-band communications antennas, a high-pressure gas tank and additional spare parts for Dextre. Launch is targeted for Friday, April 29 at 3:47 p.m. EDT.NASA It is important to protect humans from unintended electrical current flow during spaceflight. The thresholds for contact electrical shock are well established, and standards and requirements exist that minimize the probability of contact electrical shock. Current thresholds were chosen (vs. voltage thresholds) because body impedance varies depending on conditions such as wet/dry, AC/DC, voltage level, large/small contact area, but current thresholds and physiological effects do not change. By addressing electrical thresholds, engineering teams are able to provide the appropriate hazard controls, usually through additional isolation (beyond the body’s impedance), current limiters, and/or modifying the voltage levels. Risk assessment determined that the probability of an event was extremely low, and the most serious consequence is expected to be involuntary muscle contraction.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Astronauts Michael R. (Rich) Clifford and Linda M. Godwin, the assigned space-walking mission specialists for STS-76, go through a “pre-breathing” period on the Space Shuttle Atlantis’ middeck. This practice is normal procedure for space-walkers in preparation for their Extravehicular Activity (EVA) and the wearing of their Extravehicular Mobility Units (EMU). The photograph was taken with a 35mm camera by one of the crew members. Human exploration missions will require robust, flexible Extravehicular Activity (EVA) architecture protocols that include the use of a reduced-pressure cabin atmosphere enabling staged denitrogenation. Use of this atmosphere could result in compromised health and performance to the crewmember due to exposure to mild hypobaric hypoxia; of most concern are the potential effects on the increased intracranial pressure, visual impairment, cognitive performance, sensorimotor dysfunction, oxidative damage, and sleep quality. In addition to hypobaric hypoxia associated with staged denitrogenation, there are additional factors that can result in hypoxic exposure to the crewmember, such as cabin depressurization, Environmental Control, and Life Support System (ECLSS) failure, toxic exposure, or crewmember illness/injury.
Jan Zysko (left) and Rich Mizell (right) test a Personal Cabin Pressure Altitude Monitor in an altitude chamber at Tyndall Air Force Base in Florida. Zysko invented the pager-sized monitor that alerts wearers of a potentially dangerous or deteriorating cabin pressure altitude condition, which can lead to life-threatening hypoxia. Zysko is chief of the KSC Spaceport Engineering and Technology directorate’s data and electronic systems branch. Mizell is a Shuttle processing engineer. The monitor, which has drawn the interest of such organizations as the Federal Aviation Administration for use in commercial airliners and private aircraft, was originally designed to offer Space Shuttle and Space Station crew members added independent notification about any depressurizationNASA Directed Acyclic Graph Files
