Starship Flight 13 Tries Again Today: Prediction Markets Reveal Launch Odds After Engine Abort and Weather Delay
SpaceX is preparing for another attempt to launch Starship Flight 13 after separate technical and weather problems prevented the enormous rocket from leaving its launch pad. The closely watched test represents another major step in Elon Musk’s effort to turn Starship into a reusable transportation system capable of carrying satellites, cargo and eventually people beyond Earth.
The latest launch window is scheduled to open at 5:45 p.m. Central Time on Friday, July 24, at SpaceX’s Starbase facility in South Texas. The window is expected to remain open for approximately 90 minutes, allowing the company some flexibility to respond to changing weather or technical conditions. Viewers can follow the attempt through the official SpaceX Flight 13 mission page, where the webcast is expected to begin roughly 30 minutes before liftoff.
Flight 13 was originally expected to launch on July 16, but the attempt ended during the final moments of the countdown when several Super Heavy Raptor engines did not ignite correctly. The rocket’s automated systems detected the problem and stopped the launch before the vehicle could leave the pad.
SpaceX later replaced and tested multiple engines before preparing the rocket for another attempt. A rescheduled launch planned for July 23 was then abandoned because of poor weather associated with Tropical Storm Bertha. The company subsequently moved the mission to July 24, creating another opportunity for the most powerful rocket system ever developed to demonstrate its capabilities.
Why the Engine Abort Was Important
A launch abort may appear to be a failure, but an automatic shutdown before liftoff can also demonstrate that the rocket’s safety systems are performing as designed. Starship’s Super Heavy booster uses 33 Raptor engines, creating an extremely complex ignition sequence that must be completed within seconds.
When several engines failed to start properly during the earlier attempt, onboard systems prevented the booster from committing to flight. That decision protected the launch site, surrounding equipment and vehicle from a potentially more serious event.
SpaceX has also modified the booster’s hardware and software following problems experienced on Flight 12. According to the company’s official Starship programme information, the launch system is being designed to carry more than 100 metric tonnes to orbit in a fully reusable configuration. Achieving that goal requires SpaceX to identify weaknesses during testing and apply the resulting lessons to later vehicles.
The Flight 13 abort therefore provided valuable information before the rocket even moved. Engineers were able to examine the ignition sequence, replace suspected engines and conduct additional testing without losing the entire vehicle.
What Prediction Markets Say About the Launch Date
Prediction-market traders have been closely following each Starship delay. On the latest available snapshot from the Polymarket Starship Flight 13 market, traders assigned a 76% probability to the rocket launching by the end of July 24.
The probability increased to 83% for a launch by July 25, 87% by July 26 and 88% by July 27. The market placed the probability of a launch by July 31 at 93%, while the chance of Flight 13 leaving the pad by the end of August stood at 99%. Those figures indicate that traders largely expected Starship to launch soon, even though they remained less certain that the July 24 attempt would proceed without another delay.
Prediction-market prices should not be treated as official launch forecasts. They represent the collective expectations of traders reacting to public information, weather reports, company announcements and previous Starship performance.
The difference between the July 24 and July 31 probabilities is particularly revealing. Traders appeared confident that SpaceX would eventually launch Flight 13, but they continued to price in the possibility of another short postponement caused by weather, hardware or operational constraints.
Markets Expect a Difficult Booster Test
Polymarket participants were considerably more cautious about the performance of the Super Heavy booster. The market showed an 80% probability that the booster would experience an explosion during the test period covered by its resolution rules.
That percentage requires context. The market defines an explosion broadly and includes a catastrophic event occurring from the beginning of fueling until 60 minutes after the booster contacts Earth. A deliberate termination or destruction following an ocean landing could therefore satisfy the market’s conditions. The figure does not necessarily mean traders expect the booster to explode during ascent.
Flight 13 is not expected to attempt a tower catch of Super Heavy. Instead, the booster is scheduled to conduct ascent, stage separation, a boostback burn and a landing burn toward an offshore splashdown point. That mission profile helps explain why the market assigned only about a 1% probability to the booster being caught by the launch tower’s mechanical arms.
The booster’s performance will nevertheless be one of the most important parts of the test. Flight 12’s Super Heavy vehicle failed to complete its planned controlled return, prompting SpaceX to introduce hardware and software changes for the next mission. Flight 13 will reveal whether those modifications improve engine reliability during the booster’s return sequence.
Starship Splashdown Odds Remain More Optimistic
Traders showed greater confidence in the Starship upper stage than in the booster. The prediction market assigned approximately a 68% probability to Starship completing a controlled ocean splashdown.
Under the market’s rules, the upper stage must survive atmospheric re-entry, remain intact during descent and enter the water without breaking apart or exploding on impact. This creates a more demanding standard than simply reaching space or completing the ascent burn.
The complete mission is expected to last slightly more than 65 minutes. After separating from Super Heavy, Starship will continue along a suborbital trajectory before re-entering the atmosphere and targeting a splashdown in the Indian Ocean. SpaceX will use the flight to collect additional information about heat-shield performance, vehicle control and structural behaviour under demanding re-entry conditions.
Flight 13 Will Test Starlink V3 Deployment
One of the mission’s most significant objectives involves the deployment of 20 Starlink V3 satellites. Starship is expected to release the spacecraft during its suborbital flight, demonstrating the vehicle’s satellite-dispensing system and testing communication capabilities between the satellites and the existing Starlink network.
Because Flight 13 is following a suborbital trajectory rather than entering a stable orbit, the satellites are expected to re-enter Earth’s atmosphere and burn up after the demonstration. The test is therefore focused on deployment technology rather than permanently expanding the Starlink constellation.
The demonstration matters because future Starlink V3 satellites are substantially larger than earlier generations. SpaceX needs Starship’s greater payload capacity to deploy them efficiently. A successful test would provide evidence that the rocket can eventually support routine operational satellite missions rather than functioning only as an experimental vehicle.

Why Flight 13 Matters Beyond One Launch
Starship is central to several of SpaceX’s long-term ambitions. The system is being developed to carry heavy payloads into orbit, deploy next-generation Starlink satellites and support missions to the Moon and Mars.
NASA has also selected a modified version of Starship as a lunar landing system for future Artemis missions. Before the vehicle can support crewed operations, SpaceX must complete additional flight tests, orbital demonstrations, propellant-transfer experiments and landing trials. Flight 13 will not complete that entire development journey, but it could provide important evidence that the latest vehicle upgrades are moving the programme forward.
The repeated delays also illustrate the difficulty of developing a fully reusable super-heavy launch system. Weather can interrupt even a technically prepared mission, while a small ignition irregularity can stop a rocket containing millions of pounds of propellant.
Prediction markets currently suggest that most traders expect Flight 13 to launch soon. They remain less certain about whether every stage of the mission will work as intended. That distinction captures the central question surrounding Starship: leaving the pad is becoming increasingly expected, but achieving reliable, repeatable and fully reusable operations remains the much larger challenge.
