Planet Labs Taps Astroscale Partnership to Study How Satellites Reenter Earth’s Atmosphere

Planet Labs PBC (NYSE: PL) is stepping into a new kind of sustainability work, joining Astroscale Holdings Inc. and the University of Southampton in a first‑of‑its‑kind initiative to study how spacecraft reentry affects Earth’s atmosphere. The collaboration, called the Atmospheric Impact of Reentered Spacecraft (AIRS) initiative, aims to build better scientific models of what actually happens when satellites burn up or fragment as they fall back to Earth.

What the AIRS initiative will do

Astroscale, a leader in orbital‑debris removal and satellite servicing, convened the AIRS initiative as an industry‑academia collaboration focused on the atmospheric impact of reentering spacecraft. The project brings together space operators and researchers to analyze chemical compounds and material byproducts released during reentry fragmentation and vaporization, an area that has seen limited real‑world data to date.

Planet and Astroscale plan to share non‑proprietary manufacturing information—such as material compositions and approximate mass breakdowns—with researchers at the University of Southampton under controlled agreements. That data will be used to refine atmospheric models, reduce uncertainty around how reentry events behave, and move the field from purely simulated assumptions to more evidence‑based understanding.

Why Planet is involved

Planet brings extensive experience in designing, building, and operating large constellations of Earth‑observation satellites, which gives it a practical perspective on how spacecraft are constructed and eventually deorbited. The company’s chief space officer framed the move as part of Planet’s broader responsibility to the space environment, aligning its mission to “make global change visible” with a duty to understand and minimize the impact of its own industry.

For investors in PL, participation in AIRS underscores Planet’s positioning as a “responsible” space operator and thought leader on orbital sustainability, at a time when regulators and customers are paying closer attention to debris, reentry practices, and the environmental footprint of low‑Earth‑orbit mega‑constellations. While the initiative itself is research‑oriented and not a direct revenue driver, it can strengthen Planet’s brand with governments, multilateral organizations, and ESG‑focused clients.
