SpaceX Targets July 16 for Starship Flight 13, Aiming to Fix Booster Anomalies and Deploy Functional Starlink V3 Satellites

Core Event
SpaceX plans to launch the thirteenth integrated test of its Starship system on Thursday, July 16 2026 from Starbase, Texas. A 90-minute launch window opens at 6:45 p.m. ET (2245 UTC). The flight, designated Flight 13, will repeat the 65-minute sub-orbital profile of Flight 12, attempt a controlled boost-back burn of the Super Heavy booster, and deploy 20 operational Starlink V3 satellites from the upper stage.
Background & Context
Flight 12 on May 22 2026 was the first flight of the upgraded Version 3 (V3) Starship and Super Heavy. While the upper stage reached its sub-orbital trajectory, the booster failed to execute a “soft” splashdown in the Gulf of Mexico. SpaceX traced the mishap to engine-startup timing during hot-staging, which caused the booster’s directional flip to be off by roughly 90 degrees, and to the failure of five of the booster’s 33 Raptor engines to relight. The U.S. Federal Aviation Administration (FAA) subsequently required a mishap investigation. On July 13 2026 the FAA closed the review, citing heat effects on propulsion components and erroneous engine-alarm system settings as probable root causes, and accepted four corrective actions from SpaceX.
Key Figures & Groups
- Elon Musk, CEO of SpaceX, who characterizes the company’s iterative approach as “rapid unscheduled disassembly.”
- Gwynne Shotwell, President and COO, who has spoken of a target monthly flight cadence.
- SpaceX engineering team, responsible for hardware and software modifications to the booster and upper stage.
- FAA, the regulator that cleared the flight after reviewing SpaceX’s corrective plan.
- NASA, which plans to use a Starship variant as a lunar lander for the Artemis program.
Data & Statistics
- Super Heavy: 33 Raptor 3 engines; five failed to relight on Flight 12.
- Starlink V3 payload: 20 satellites, each offering 1 Tbps downlink and 160 Gbps uplink—over ten times the downlink capacity of earlier V2 Mini satellites.
- Six satellites carry cameras to image the heat-shield tiles during re-entry.
- The sub-orbital flight will last just over one hour from liftoff to final splashdown.
Why It Matters / Impact
Successful execution of Flight 13 would validate the booster-flip and engine-re-light fixes, clearing the path for the first orbital Starship launch on the subsequent mission. Achieving a reliable in-space Raptor relight is a prerequisite for NASA’s Artemis III/IV lunar lander and for in-orbit propellant transfer—key steps toward crewed lunar missions and eventual Mars exploration. Deploying functional Starlink V3 satellites demonstrates Starship’s unique capability to launch payloads too large for Falcon 9, accelerating the expansion of SpaceX’s broadband constellation, which now serves roughly 10.3 million users via more than 9,600 operational satellites.
Official Statements & Responses
SpaceX announced that the startup sequence has been modified to tolerate timing variability and to “more reliably flip in the desired direction,” adding hardware upgrades to improve booster relight reliability and updating engine-alarm and abort logic for multi-engine conditions. The company also noted that “several hardware and operational modifications have been made to address the interconnected causes,” with further Raptor reliability improvements planned. The FAA’s final statement confirmed that the investigation identified heat effects and erroneous alarm settings as the most probable causes and that SpaceX’s four corrective actions satisfy regulatory requirements.
Criticism & Opposition
No formal criticism appears in the sourced material; the FAA’s investigation itself reflects regulatory caution, but the agency ultimately granted clearance after reviewing SpaceX’s corrective plan.
Conflicting Reports & Gaps
Sources differ on the primary cause of the booster failure: SpaceX emphasizes engine-startup timing leading to a 90-degree flip, while the FAA highlights heat damage and engine-alarm mis-settings. Neither source provides a detailed mechanistic explanation of how these factors interacted, leaving a technical gap pending post-flight analysis.
Verbatim Quotes
- “At stage separation on Flight 12, slight differences in engine startup on the ship caused the directional flip of the booster to be off by approximately 90 degrees,” — SpaceX
- “The startup sequence has been modified to be more robust to timing variability and more reliably flip in the desired direction, which is done to increase overall performance,” — SpaceX
- “Several hardware and operational modifications have been made to address the interconnected causes, with additional reliability improvements planned in upcoming versions of the Raptor engine,” — SpaceX
- “rapid unscheduled disassembly.” — Elon Musk, CEO
- “erroneous engine alarm system settings.” — Federal Aviation Administration
What’s Next
If Flight 13 succeeds, SpaceX intends to attempt the first orbital Starship launch on Flight 14, a step required for full-scale Starlink V3 deployment and for meeting NASA’s Artemis lunar-lander requirements.
