NASA estimates SpaceX Falcon 9 upper stage created 60-foot-wide lunar crater

NASA’s Lunar Reconnaissance Orbiter has provided the first detailed images of a lunar crater created by a discarded SpaceX Falcon 9 upper stage. The stage, part of a 2025 mission carrying payloads for Firefly and ispace, was on a collision course with the moon after delivering its cargo. The resulting crater, estimated at 60 feet wide and 10 feet deep, offers a rare opportunity to study the effects of high-velocity impacts on the lunar surface. The images also reveal fresh material excavated from beneath the surface, contrasting with the darker, weathered regolith around it.

For engineers, this event underscores the challenges of managing space debris, particularly in cislunar space. The trajectory of the discarded stage was predictable, but its impact highlights the need for better disposal strategies to avoid unintended collisions. The data from this crater could improve models for predicting how discarded hardware behaves upon impact, which is critical for planning future lunar missions. The event also raises questions about the long-term sustainability of commercial lunar operations, where multiple payloads are often launched on a single vehicle.

The Falcon 9 upper stage was not the only SpaceX hardware to make headlines recently. A Starship from the 13th test flight was recovered near Christmas Island, Australia, for post-flight analysis. While the two events are unrelated, they collectively illustrate the growing footprint of commercial spaceflight. The lunar crater serves as a reminder that even well-planned missions can leave lasting marks on celestial bodies, while the Starship recovery demonstrates the logistical challenges of retrieving hardware from remote locations.

The images from NASA’s LRO provide a unique dataset for planetary scientists studying lunar geology. The fresh material exposed by the impact offers insights into the composition of the moon’s subsurface, which has been altered over time by solar wind and micrometeorite impacts. For engineers, the event is a case study in the unintended consequences of spaceflight, where even a discarded upper stage can become a scientific opportunity. The data could inform future mission planning, particularly for lunar landers and orbiters that must navigate an increasingly crowded cislunar environment.
