TLDRs
- SpaceX aborted its Starship V3 launch after multiple engines failed to ignite properly.
- Elon Musk said two engines will be replaced before another launch attempt next week.
- The failed mission sent SpaceX shares down more than 4% in after-hours trading.
- The test was meant to deploy next-generation Starlink satellites and advance future ambitions.
SpaceX shares fell more than 4% in after-hours trading on Thursday after the company’s second attempt to launch its upgraded Starship V3 rocket ended in an automatic abort moments before liftoff.
The setback came just as the launch sequence reached ignition at SpaceX’s Starbase facility in South Texas. While the Super Heavy booster began firing its engines, the launch was halted automatically after multiple engines failed to start correctly, preventing the vehicle from leaving the pad.
The failed test marked another hurdle for the aerospace company as it continues developing Starship, the world’s largest rocket system, which is expected to play a central role in future satellite deployments, lunar missions, and eventually human missions to Mars.

Engine Failure Halts Countdown
Following the aborted launch, SpaceX CEO Elon Musk confirmed that the automatic safety system canceled the mission after detecting engine startup issues.
According to Musk, several engines did not ignite as expected, prompting the onboard system to terminate the launch sequence. He added that the company plans to replace two engines before making another launch attempt, which is now expected sometime next week.
Broadcast footage showed the countdown progressing normally after a brief hold approximately one minute before liftoff. Once the countdown resumed, the launchpad’s water suppression system activated and the booster appeared to begin ignition before shutting down almost immediately.
Graphics displayed during the livestream suggested that four of the upgraded Raptor engines failed to ignite, although SpaceX has not yet released a detailed technical assessment.
Stock Reacts To Launch Setback
Investors responded quickly to the unsuccessful mission.
SpaceX shares, which had already closed below their initial public offering price of $135 earlier in the day, declined by more than 4% in after-hours trading following news of the launch abort.
The company only recently entered the public markets after completing what became the largest IPO in history in June, raising more than $85 billion. Although investor enthusiasm initially pushed the company’s valuation to levels comparable with some of the world’s largest technology firms, the stock has experienced persistent selling pressure over the past month.
Thursday’s failed launch added to investor concerns as markets continue evaluating the pace of Starship’s development alongside the company’s long-term commercial ambitions.
Mission Carried Strategic Importance
The flight represented more than another routine test.
SpaceX intended to use the mission to deploy the first third-generation Starlink satellites, a key milestone for expanding its satellite internet network. While the satellites were expected to burn up roughly 20 minutes after deployment because Starship has yet to demonstrate a successful orbital mission, the test would have provided valuable performance data for both the upgraded rocket and the new satellite design.
Starlink remains the company’s primary revenue source and its only consistently profitable business segment. Successive improvements to both the launch system and satellite network are viewed as essential for supporting SpaceX’s broader strategy, including plans to build orbital infrastructure capable of supporting future space-based computing and communications services.
The company has repeatedly emphasized that rapid testing remains central to Starship’s development philosophy, with each mission designed to gather engineering data regardless of whether every objective is achieved.
Recovery Efforts Already Underway
Thursday’s launch attempt followed the inaugural Starship V3 flight in May, which delivered mixed results.
Although the upgraded rocket successfully lifted off and deployed Starlink simulator payloads, the Super Heavy booster experienced a malfunction before completing its planned splashdown demonstration in the Gulf of Mexico. The incident prompted a Federal Aviation Administration review, though regulators cleared Starship for another flight earlier this week after SpaceX implemented corrective measures.
The upper stage also experienced an engine loss during the May mission but still managed to complete its planned controlled descent over water.
Following Thursday’s aborted attempt, SpaceX engineers must first safely drain propellant from both the Super Heavy booster and Starship upper stage before conducting a detailed investigation into the engine startup failure.
With another launch already targeted for next week, the company hopes the setback will prove to be a temporary delay rather than a major obstacle in advancing one of the world’s most ambitious spaceflight programs.
