With two lucky 150-meter jumps in the bag for SpaceX, Starship’s tests are to enter the next phase.The Starship SN6’s 150-meter good fortune followed only a few weeks after SN5’s good fortune.
The good luck of the SN6 test will have increased confidence in many elements of the Starship prototype, ranging from structures to propulsion and control capability.
Chief designer Elon Musk said the re-testing would allow engineers to adjust the way they launch and land vehicles, comparisons already observed with the Starhopper flight, the inaugural launch of SN5 and then SN6.
The processing improvements surrounding the test are also improving, with SN6 simply acting as a cryoprotection test and a static Raptor SN29 Fire before you can continue with the jump.
While weather situations canceled attempts to open the launch window, SN6 jumped off the launch pad Thursday without any disruption before an exact landing on the adjacent platform.
Although SN6 was slightly bent on post-landing images, the spacecraft’s legs have the ability to cushion an additional cargo landing, as was probably the case with SN6 returning under the force of a single Raptor (SN29) in a staggered placement engine..

Despite thunderstorms in the local domain on Saturday, engineers worked all weekend to prepare the SN6 for a return to production facilities.
SN7.1:
The next prototype to accommodate Starhopper, the permanent resident of the release site, will be the SN7.1 verification tank.
SN7.1 follows the SN7, which is also a control tank and deliberately driven to the point of bursting.The SN7.1 is a larger control tank made of 304L series stainless metal (or at least one variant of this alloy).
Although it is not the “final” alloy that SpaceX expects to use on spacecraft and is long-term super-weighed, all previous spacecraft have been manufactured with the 301 series alloy, while SN7, SN7.1 and all are long-term spacecraft.are made of 304L.
As such, SN7.1 will provide an important understanding of the stress the tank can face before it breaks, knowledge that will be incorporated into the SN8 verification program.
Work on the final touch of the SN7.1 control tank at the production plant is close to the final touch, so it’s imaginable to travel to the launch site next week.
With two release mounts available, it remains to be noted whether SN7.1 will settle on the normal Starship mount, or at the time of mount verification, or transfer between the two.before being driven to the breaking point.
SN5:
The SN5 spacecraft is expected to jump at least once more, prosecuting it at the production facility for deployment on the platform after SN7.1 has finished the journey.
SN5 most likely sticks to SN6’s subtle verification regimen of a cryoprotection check, a static chimney check, with the tip of the feet in a 150-meter jump.
Currently, SN5 remains located outside Mid Bay, acting as a purter of High Bay’s structure efforts that now dominate it.
It is known whether SN5 still hosts, or will reuse, Raptor SN27 for the time being.
SN8:
Starship SN8 will mark the next phase as the first prototype to fly with 3 Raptor engines, a nose cone and aerodynamic surfaces.
While SN5 is making way for the latest SN8 stacking operations in Mid Bay, this new vessel is now waiting to be tested.
Currently, SN8 checks will have to wait until SpaceX has completed burst checking targets with SN7.1 and even the possible momentary hop with SN5.
Several new and attractive elements will be used in the SN8 current, such as the most likely deployment of the nose cone separately, to mate with the SN8 tank at the release site.
SN8 will mark the first time 3 Raptor engines will be fired on a spacecraft.
The initial altitude target for check release has still been confirmed.
With a 20km launch option, SN8 can be initially introduced at decreasing altitude, with incremental testing as Starship makes its first horizontal drop to launch before the Raptors push vertically back for a landing.
SN9:
Once SN8 leaves the intermediate bay, sections for SN9 will begin to accumulate.The meeting of this long-running shipment is known thanks to photographs of the sections lately in the last outdoor preparation of the production buildings of “Big Tent” through the watchman Mary (@bocachicagal), NSF photojournalist in Boca Chica and long-time resident.
The most recent milestone was the coating of the SN9 Thrust Dome and a stack of five sedimented rings, which will attach the segment of the SN9 tank to the nose, seen outdoors.
The role of SN9 is potentially for dating between SN5 and SN6, safeguarding SN8 for the complex control regime.
SN10 and long-distance vehicles:
With devices such as thrust washers, descents and contact legs arriving almost every two weeks, as well as various walls and welding rings inside the “big tents”, more boats are likely to be born.
The confirmation came by observing the arrival of classified SN10 to Boca Chica last week.
While there may be speculation about the testing regime to which the SN10 will be subjected, this confirms SpaceX Boca Chica’s increasing production rate.
Although curtains labeled Super Heavy have not yet been noticed in the wild, a lot of metal rings are being assembled in Boca Chica, which can turn out to be the metal that will be used to create the rings of what will be the first of all will be a double Raptor thruster.
This first Super Heavy booster will be stacked inside the new high bay, which is waiting for its roof section, and then head to the support below the structure at orbital launch for its own jump test.
Initial verification of super-heavy vehicle prototypes will pave the way for additional innovations in the full battery amplifier, which, probably thanks to the impressive verification effects in SpaceX McGregor, is now expected to fit 28 Raptor engines of 31.
