    NASA Completes Latest Scientific Balloon Campaign From Antarctica

    A white scientific balloon rises into the bright blue sky above snowy Antarctica. The sky and the balloon take up most of the image, with the ground only being a small white stripe at the bottom of the photo. The balloon has a long white "tail" with orange and black portions.

    NASA’s Scientific Balloon Program has completed four successful Antarctica flights during a long-duration campaign that began in early December. The balloons launched from the agency’s facility located near the U.S. National Science Foundation’s McMurdo Station on the Ross Ice Shelf.   The General AntiParticle Spectrometer (GAPS) balloon lifted off Dec. 15. The GAPS payload is an experiment designed to detect anti-matter particles entering Earth’s atmosphere to help reveal the origin of dark matter — an invisible […]

    Two NASA Scientific Balloon Launches Planned From Antarctica

    A large scientific balloon payload is being lifted by a black crane against a bright blue Antarctic sky. The payload consists of multiple tiers of white protective panels or covers arranged in a cylindrical configuration, with solar panels visible on the top section and various antennas protruding upward. The equipment is suspended by cables and positioned over a wheeled transport cart on the snow-covered ground. A technician in a bright yellow safety vest operates the crane from an elevated platform on the left side of the image

    NASA’s Scientific Balloon Program is back in Antarctica for another long-duration scientific balloon campaign, with two launches planned from the icy surface. Launch operations will begin early December from the agency’s facility located near the U.S. National Science Foundation’s McMurdo Station on the Ross Ice Shelf. To follow the missions, visit NASA’s Columbia Scientific Balloon […]

    New Mexico Scientific Balloon Campaign Update – Sept. 15

    The Electron Losses driven by VLF EmissionS (ELVES) mission launched at 10:04 a.m. EDT (8:04 a.m. MDT) on Sept. 15, 2025. The balloon and payload reached a float altitude of 125,000 feet and flew for 8 hours, 12 minutes. The experiment includes multiple detection methods for both Very Low Frequency (VLF) emissions and electron precipitation, including magnetometers, x-ray detectors, and cosmic noise absorption measurements, advancing our understanding of radiation belt dynamics and ionospheric interactions.

    To follow the missions in the 2025 Fort Sumner campaign, visit NASA’s Columbia Scientific Balloon Facility website for real-time updates of balloons’ altitudes and locations during flight.

    New Mexico Scientific Balloon Campaign Update – Sept. 14

    NASA launched two scientific balloon missions from the agency’s Fort Sumner, New Mexico, launch facility Sunday, Sept. 14, 2025. This marks the first time two scientific balloons were launched on the same day since 2011.

    The JPL-Remote mission launched at 10:12 a.m. EDT (8:12 a.m. MDT) Sept. 14, 2025. The balloon and payload reached a float altitude of 127,000 feet and flew for 12 hours, 58 minutes. The mission’s main goal is to measure how different gases are layered in Earth’s atmosphere to check satellite data and track long-term changes since 1989.

    The Cosmic Dust Collection Project (CDCP) mission launched at 12:10 p.m. EDT (10:10 a.m. MDT). The balloon and payload reached a float altitude of 125,000 feet and flew for 8 hours, 36 minutes. The mission’s aimed to capture cosmic dust at different altitudes in Earth’s atmosphere to study how much of this dust has contaminated the stratosphere.

    To follow the missions in the 2025 Fort Sumner campaign, visit NASA’s Columbia Scientific Balloon Facility website for real-time updates of balloons’ altitudes and locations during flight.

    New Mexico Scientific Balloon Campaign Update- Sept. 4

    The High-Altitude Student Platform 2 (HASP2) successfully launched at 8:28 a.m. MDT (10:28 a.m. EDT) Thursday, Sept. 4 and reached a float altitude of nearly 122,000 feet. HASP remained in flight for a total of 11 hours,40 minutes. Science reports a successful flight. The balloon and payload have safely landed, and recovery efforts are underway.

    The HASP2 program is a collaborative effort between Louisiana Space Grant Consortium at Louisiana State University (LaSPACE - LSU), NASA SMD: Astrophysics Division, NASA Balloon Program Office (BPO) and the Columbia Scientific Balloon Facility (CSBF) to develop and operate an inexpensive platform that can be used to flight test compact satellites, prototypes and other small payloads designed and built by students. The High Altitude Student Platform 2 (HASP2) is designed to carry up to twenty-four (24) student payloads at a time to an altitude of about 110,000 feet with flight durations of 15 to 20 hours.

    Student Payloads and Organizations for 2025 include:

    • Big Red Sat 1.5 – The University of Nebraska Lincoln
    • STRAINS 4.0 – Sint-Pieters College Jett
    • Bat Sat – University of Colorado, Colorado Springs
    • FLC Ionizing Radiation vs Solar Insolation (IRSI) Experiment – Fort Lewis College

    New Mexico Scientific Balloon Campaign Update- Aug. 21

    Aug. 21, 2025: The Salter Test Flight launched at 9:21 a.m. EDT (7:21 a.m. MDT) Thursday, Aug. 21 from the agency’s balloon launch facility, marking the first successful balloon flight of the campaign. The balloon and payload reached a float altitude of 124,000 feet, and flew for a total of 5 hours, 4 minutes. The hardware test flight reported a healthy balloon and flight systems, and requirements were met before successful termination. Several smaller payloads, or piggyback missions, rode along to support science and technology development, including numerous student experiments. Recovery efforts are underway.
