As humanity expands its presence in space, the safety of our growing network of satellites and future off-world infrastructure is increasingly at risk from meteoroid storms and other celestial hazards. This pressing issue has led to a new proposal that has earned researchers Brian Murphy and Richard Cannon from the University of Edinburgh this year’s Schweickart Prize, named after Apollo 9 astronaut Rusty Schweickart, a strong advocate for planetary defense.
In a recent announcement, Schweickart emphasized the urgency of addressing these emerging threats: “As human activity and vital interests rapidly expand into regions beyond the protective shield of our atmosphere, the number of passing objects capable of causing serious damage to both life and critical infrastructure increases dramatically.”
Proposal Overview
Murphy and Cannon’s winning proposal focuses on the potential dangers posed by streams of space debris and smaller meteoroids, which, while they may burn up upon entering Earth’s atmosphere, can inflict significant damage in the vacuum of space. They advocate for the establishment of an international commission to assess these threats, proposing a coordinating body named WARDEN, which stands for Warning Network for Asset Resilience From Dusts, Ejecta and NEOs.
Historical Context and Current Risks
The researchers highlighted that the risk to satellites has escalated dramatically, with the number of operational satellites increasing from fewer than 1,000 to over 17,000 since 2009, largely due to the expansion of SpaceX’s Starlink constellation. They estimate that exposure to meteoroids has increased by a factor of 10 to 100, raising concerns about potential damages that could reach into the billions. Murphy noted, “Even when we had a hundredth of the assets in space, there was still damage that was in the $1.2 billion range.”
Future Steps and Timeline
Murphy and Cannon plan to utilize their $10,000 award to convene meetings aimed at forming the International Commission on Space Infrastructure Resilience (ICSIR). Their first meeting is scheduled to take place at the University of Edinburgh, with subsequent gatherings planned every six months. They have also identified specific meteoroid storms in 2028, 2033, and 2034 that could pose significant risks to spacecraft, particularly during the Perseid and Leonid meteor showers.
As they move forward, Murphy expressed the importance of evolving planetary defense strategies to protect the critical infrastructure that will support humanity’s future in space. “We’re about to expand into the final frontier, further than we’ve ever gone before, and bring with us the critical infrastructure for our civilization,” he stated.
