UPCOMING LAUNCH Starship's Seventh Flight Test
The seventh flight test of Starship is preparing to launch Wednesday, January 15. The 60-minute launch window will open at 4:00 p.m. CT.
A live webcast of the flight test will begin about 35 minutes before liftoff, which you can watch here and on X @SpaceX. You can also watch the webcast on the new X TV app. As is the case with all developmental testing, the schedule is dynamic and likely to change, so be sure to check in here and stay tuned to our X account for updates.
The upcoming flight test will launch a new generation ship with significant upgrades, attempt Starship’s first payload deployment test, fly multiple reentry experiments geared towards ship catch and reuse, and launch and return the Super Heavy booster.
A block of planned upgrades to the Starship upper stage will debut on this flight test, bringing major improvements to reliability and performance. The vehicle’s forward flaps have been reduced in size and shifted towards the vehicle tip and away from the heat shield, significantly reducing their exposure to reentry heating while simplifying the underlying mechanisms and protective tiling. Redesigns to the propulsion system, including a 25 percent increase in propellant volume, the vacuum jacketing of feedlines, a new fuel feedline system for the vehicle’s Raptor vacuum engines, and an improved propulsion avionics module controlling vehicle valves and reading sensors, all add additional vehicle performance and the ability to fly longer missions. The ship’s heat shield will also use the latest generation tiles and includes a backup layer to protect from missing or damaged tiles.
The vehicle’s avionics underwent a complete redesign, adding additional capability and redundancy for increasingly complex missions like propellant transfer and ship return to launch site. Avionics upgrades include a more powerful flight computer, integrated antennas which combine Starlink, GNSS, and backup RF communication functions into each unit, redesigned inertial navigation and star tracking sensors, integrated smart batteries and power units that distribute data and 2.7MW of power across the ship to 24 high-voltage actuators, and an increase to more than 30 vehicle cameras giving engineers insight into hardware performance across the vehicle during flight. With Starlink, the vehicle is capable of streaming more than 120 Mbps of real-time high-definition video and telemetry in every phase of flight, providing invaluable engineering data to rapidly iterate across all systems.
While in space, Starship will deploy 10 Starlink simulators, similar in size and weight to next-generation Starlink satellites as the first exercise of a satellite deploy mission. The Starlink simulators will be on the same suborbital trajectory as Starship, with splashdown targeted in the Indian Ocean. A relight of a single Raptor engine while in space is also planned.
The flight test will include several experiments focused on ship return to launch site and catch. On Starship’s upper stage, a significant number of tiles will be removed to stress-test vulnerable areas across the vehicle. Multiple metallic tile options, including one with active cooling, will test alternative materials for protecting Starship during reentry. On the sides of the vehicle, non-structural versions of ship catch fittings are installed to test the fittings’ thermal performance, along with a smoothed and tapered edge of the tile line to address hot spots observed during reentry on Starship’s sixth flight test. The ship’s reentry profile is being designed to intentionally stress the structural limits of the flaps while at the point of maximum entry dynamic pressure. Finally, several radar sensors will be tested on the tower chopsticks with the goal of increasing the accuracy when measuring distances between the chopsticks and a returning vehicle during catch.
