Planet Labs, a leading provider of daily data and insights about change on Earth, announced its role as a founding participant in the Atmospheric Impact of Reentered Spacecraft (AIRS) initiative. Convened by Astroscale Holdings, the AIRS initiative is a first-of-its-kind industry-academia collaboration designed to improve scientific understanding of the effects of spacecraft reentry on Earth’s atmosphere.

As activity in low Earth orbit (LEO) accelerates, the number of satellites reentering the atmosphere is expected to rise significantly. While historical efforts have focused on orbital debris, the AIRS initiative addresses the underexplored research area of chemical compounds released during reentry fragmentation and vaporization. By sharing non-proprietary manufacturing data and material compositions, Planet and Astroscale will empower academic researchers at the University of Southampton to build high-fidelity atmospheric models.

"Our mission to make global change visible starts with a deep responsibility for the space environment in which we operate," said James Mason, Chief Space Officer at Planet. "Sustainable space operations must account for a satellite’s entire lifecycle, including its eventual reentry. By providing data to the AIRS initiative, we are helping the scientific community move past simulations and toward a factual, data-driven understanding of our industry’s atmospheric footprint."

“Spacecraft reentry has long been treated as an optimal mission endpoint, but it is increasingly clear that we need a deeper scientific understanding of what happens during this phase,” said Mike Lindsay, Chief Technology Officer at Astroscale. “By enabling industry to contribute real-world data in a trusted way, AIRS removes critical barriers for atmospheric research and ensures space sustainability is guided with the most accurate and up-to-date information.”

Planet’s participation demonstrates its commitment to Agile Aerospace and transparency – extending that transparency from the Earth’s surface to the very atmosphere that protects it. By contributing data from the world's largest Earth observation fleet, Planet is helping to ensure that the future of LEO is guided by evidence-based science.
