China Aims To Catch Rockets With Wires In Reusable Rocket Push

China's space ambitions are taking a unique turn with their plan to utilize constricting wires to snag returning rocket stages, according to a report by Space.com. The China Aerospace Science and Technology Corporation (CASC), the country's main space contractor, aims to debut this technique with reusable rockets launching in 2025 and 2026.

This approach deviates from the currently popular method employed by SpaceX's Falcon 9 rockets, which rely on landing legs after a propulsive descent. Instead, CASC plans to equip their rockets with hooks that will snag on high-tension wires as they descend, presumably over a sea platform.

While details are scarce, a video released by Chinese state media showcased a human-rated Long March 10 rocket deploying these hooks and undergoing a controlled re-entry. This method, if successful, could offer several advantages. It eliminates the need for complex landing leg mechanisms, potentially reducing weight and cost. Additionally, catching the rockets over water could be safer than land-based pad returns, especially for densely populated areas.

However, concerns remain. The successful deployment and precise control of the wires during descent will be crucial for a safe capture. The immense forces involved during rocket retrieval also raise questions about the structural integrity of the wires and the captured rocket stage.

Only time will tell if China's "celestial snare" proves to be a viable alternative in the growing field of reusable rockets. Their 2025 and 2026 launch windows will be a key test for this ambitious endeavor.
