TOBIAS (Tethered Balloon Imaging and Atmospheric Sampling)
TOBIAS (Tethered Balloon Imaging and Atmospheric Sampling) This illustration shows TOBIAS, or Tethered Balloon Imaging and Atmospheric Sampling, a concept presented at the 2025 NASA Innovative Advanced Concepts (NIAC) Symposium. The proposed mission would suspend a basketball-sized instrument package beneath a high-altitude balloon in Venus’s atmosphere, using a long tether to capture detailed images of the planet’s surface and analyze its atmosphere. By harnessing wind power and innovative cooling systems, TOBIAS could provide a stable, long-term platform for studying Venus’s geology and climate from within its clouds. NASA / Ben Hockman
