SpaceX is scheduled to launch its 13th integrated Starship test flight from its Starbase facility in South Texas today, July 16, 2026. The mission, utilizing a new Version 3 vehicle, aims to test critical engine relight capabilities and deploy 20 Starlink satellites, marking a significant step toward achieving orbital readiness for NASA’s Artemis III mission.
Flight 13 Mission Objectives and Starlink Deployment
SpaceX is targeting a 90-minute launch window for the 13th test flight of its Starship megarocket, opening at 5:45 p.m. CDT (6:45 p.m. EDT / 2245 UTC) today. Unlike previous test flights, this mission includes the deployment of 20 production Starlink V3 satellites.

While the mission remains suborbital, SpaceX intends to demonstrate the vehicle’s ability to communicate with the broader Starlink network. According to a pre-flight update from SpaceX, the satellites will extend solar arrays and antennas and will attempt to connect with the larger Starlink constellation via high-capacity lasers. The satellites are expected to demise upon reentry approximately 20 minutes after deployment.
Addressing Flight 12 Anomalies and Hardware Upgrades
The current mission follows a 52-day mandatory stand-down period required by the Federal Aviation Administration (FAA) following the May 22 Flight 12 anomaly.
To mitigate these risks for today’s flight, SpaceX has implemented four specific corrective actions. The startup sequence for the Raptor engines has been modified to be more tolerant of timing variability, which should prevent the directional flip errors that plagued the previous mission. Furthermore, the company has updated its engine abort logic to better reflect the conditions that occur during multi-engine flight environment.
The Path to Artemis III and Orbital Refueling
The stakes for today’s test extend beyond mere hardware validation. NASA has contracted SpaceX to develop a lunar lander configuration for the Artemis III mission, slated for 2027. A central requirement for that mission is the ability to perform orbital propellant transfers, a maneuver that hinges on the successful in-space reignition of Raptor Vacuum engines.
“SDA leverages spiral development to deploy and proliferate new capability into a new generation of the PWSA every two years, called a ‘tranche,’ to continually increase capability used by the warfighter.”

While Starship undergoes testing in Texas, SpaceX is simultaneously supporting broader U.S. military space objectives. Earlier today, Space reported that a Falcon 9 rocket launched 21 satellites for the Space Development Agency’s “Tranche 1 Transport Layer.” This constellation is designed to provide global communications access and deliver persistent regional encrypted connectivity in support of warfighter missions around the globe, underscoring the company’s dual focus on commercial launch dominance and national security infrastructure.
The company continues to iterate on its heat shield design, incorporating load-sensing tiles on Ship 40 to gather data as the vehicle experiences higher dynamic pressure on ascent. These tests are intended to refine the vehicle’s thermal protection system, a prerequisite for the rapid, full reusability that Elon Musk envisions for future Mars-bound missions.
As the countdown proceeds today, engineers will be monitoring the Raptor Vacuum engine relight test closely. Failure to execute this maneuver successfully would delay the demonstration of orbital capability, potentially impacting the timeline for the upcoming lunar missions.
