TLDR
- On August 5, a discarded SpaceX Falcon 9 upper stage collided with the lunar surface, forming an 18-meter-wide crater
- High-resolution photographs from NASA’s Lunar Reconnaissance Orbiter reveal the impact site in unprecedented detail
- The rocket stage had been tumbling through space for more than 12 months following its January 15 launch
- According to SpaceX, executing a controlled reentry wasn’t feasible given the energy requirements of lunar missions
- Trading at $142.23 on Wednesday, SpaceX shares declined 0.8% as market attention shifts to an impending share unlock and upcoming Starship launch
An abandoned upper stage from a SpaceX Falcon 9 rocket collided with the moon’s surface on August 5, carving out a crater approximately 60 feet across. NASA has just published the most detailed photographs of the collision site to date.
NASA’s Lunar Reconnaissance Orbiter, traveling at approximately one mile per second at an altitude of 60 miles above the moon, captured these remarkable images. Mission engineers carefully adjusted the spacecraft’s camera orientation to photograph the crater during each orbital pass.
According to scientific analysis, the impact zone measures approximately 18 meters in diameter with a depth of less than three meters. The collision released energy equivalent to roughly three tons of explosive material.
What Caused the Lunar Collision?
Launched on January 15 with lunar landers as its payload, the Falcon 9 second stage couldn’t be safely deorbited following mission completion. SpaceX explained that lunar missions demand significantly more propellant than standard orbital launches, making controlled reentry unfeasible.
“We typically schedule controlled deorbits for our Falcon second stages, ensuring they reenter safely over oceanic regions,” SpaceX stated in an X platform post. During the intervening year, gravitational forces and solar radiation gradually altered the rocket stage’s trajectory until it eventually struck the moon.
SpaceX emphasized its commitment to “actively works to be as responsible as possible with hardware left in space.”
Orbital Congestion Becomes a Concern
This incident has drawn attention to the increasingly congested environment beyond Earth’s atmosphere. SpaceX’s Starlink network now comprises over 10,000 active satellites providing broadband connectivity to more than 12 million customers worldwide.
Amazon and China’s Qianfan satellite system are preparing to deploy thousands of additional spacecraft. The proliferation of orbital objects inevitably generates more space debris, prompting discussions about sustainable space traffic control.
Proposed solutions range from enhanced debris monitoring systems to active removal technologies, along with spacecraft designs that ensure complete atmospheric burnup during decommissioning.
SpaceX’s upcoming Starship vehicle features full reusability. Both the booster and upper stage will return to Earth intact, eliminating the possibility of abandoned hardware drifting toward celestial bodies.
The fourteenth Starship demonstration flight is scheduled for later this month, drawing significant investor interest.
Market Performance and Share Price
The lunar impact incident hasn’t influenced SpaceX’s market valuation. Following its June public offering at $135 per share, the stock climbed to just above $143 before experiencing Wednesday’s modest decline to $142.23.
Approximately 319 million shares currently held by founding investors will enter the market on August 20. This pending share unlock previously created downward pressure on the stock price before positive second-quarter financial results sparked a rebound.
On Wednesday, the S&P 500 index gained 0.4% while the Dow Jones Industrial Average advanced 0.2%.
