## Resource

The Space Show Presents Dr. Siamak Hesar and Araz Feyzi on the Shenzhou-20 Debris Scare, Tuesday, 2-20-26. Quick Summary: The Space Show hosted a discussion on the orbital debris problem, focusing on the recent Shenzhou 20 debris scare and its implications for space safety. Araz Feyzi and Siamak Hesar from Kayhan Space explained the challenges of tracking and mitigating space debris, highlighting the need for better coordination between satellite operators and advancements in debris removal technology. They discussed Kayhan Space’s role in providing space traffic coordination services and their recent collaboration with SpaceX’s Stargaze system to enhance debris tracking capabilities. The conversation also touched on the potential risks of Kessler syndrome and the importance of responsible satellite behavior to prevent further debris generation. Detailed Summary: The meeting began with introductions and a discussion focusing on the Shenzhou debris scare in low Earth orbit but is not limited to that topic. Our guest Araz explained the orbital debris problem. We addressed the risks and concerns associated with space debris, particularly in the context of recent Chinese human spaceflight missions. The conversation also touched on the business of Kayhan Space and how it relates to addressing these space debris issues. Araz discussed the rapid growth in satellite launches over the past decade, highlighting the shift from large, expensive government satellites to smaller, affordable commercial ones. He explained the increasing threat of orbital debris, estimating over a million pieces larger than 1 centimeter in diameter, and described a recent incident involving a crack in a Chinese space station caused by debris. David asked about the risks to astronauts during spacewalks…
