SpaceX has not skilled a lot success with the Block 2 model of Starship since its introduction earlier this 12 months.
What was meant to usher in a brand new period for this system, together with a potential ship catch in 2025, has as an alternative devolved into SpaceX repeatedly making an attempt to realize the identical goals that had been focused throughout a number of consecutive flights. Ship 37 goals to interrupt this streak throughout Flight 10, which is about to launch no sooner than August 24 at 6:30 p.m. Central Daylight Time.

Block 2 Flights So Far
This journey began with Ship 33 and Booster 14 for Flight 7 on January 16, 2025. The complete stack lifted off, and Booster 14 carried out completely, changing into the second booster to be caught.
This might be the one vivid spot on this mission, as shortly after the catch, SpaceX misplaced communication with Ship 33 as fires raged in its attic and engine part. This led to a extremely energetic explosion of the ship and a diversion of many industrial flights as a result of particles space over the Caribbean. The leaks that brought about these fires had been as a consequence of harmonic vibrations within the ship.

The second Block 2 ship to fly was Ship 34 paired with Booster 15. Flight 8 lifted off on March 6. This turned a repeat of Flight 7, the place the booster got here again for catch, however the ship was once more misplaced earlier than Second Stage Engine Cutoff (SECO). As soon as once more, the ship had fires within the engine bay, however these had been a results of potential preloading points with the Raptor engine mounts.
Preloading refers back to the quantity of torque utilized to the mounting bolts for set up. This led to propellant leaking into the attic and engine bay and ultimately brought about a middle raptor to blow up, taking different engines with it. Ship 34 then spun uncontrolled and exploded.
The newest flight, Flight 9, was Ship 35 paired with Booster 14-2 as SpaceX makes an attempt to reuse a booster. This flight had at the least one constructive end result for the ship: Ship 35 made it previous SECO however misplaced management through the coast part as a result of the methane tank pressurization line that enters the highest of the ahead dome failed on the diffuser. This brought about a pressurization drawback within the payload bay and within the methane tank.
Because of this problem, Ship 35 reentered in an uncontrolled method and was misplaced with out finishing any main goals. Booster 14, nonetheless, accomplished an ideal ascent as a reused booster, however was misplaced through the extremely experimental part of flight that SpaceX was conducting on the glide again and touchdown burn.

Then there’s Ship 36, which didn’t fly, however actually made a reputation for itself. With being round 10 days away from flight and making an attempt to finish its six-engine static hearth, it skilled an anomaly on June 18, which resulted within the lack of the ship on the Masseys static hearth check stand.
The trigger was a nitrogen Composite Overwrapped Strain Vessel (COPV) shedding integrity and exploding; the ensuing explosion ruptured the propellant header tank switch traces and combined the Liquid Oxygen (LOX) and Liquid Methane (LCH4).
This then resulted within the ship utterly unzipping after which exploding, ensuing within the destruction of the ship, main injury to the Masseys Methane tank farm, the static hearth stand, and its flame deflector. Masseys continues to be present process a redesign and restore.

Booster 16 and Ship 37
Booster 16 was static hearth examined on June 6, when it was slated to fly with Ship 36. Nevertheless, as a consequence of Ship 36’s anomaly, it needed to wait to fly till Ship 37 was prepared.
Nothing has actually modified with the booster throughout that point, at the least externally, in comparison with the previous few boosters. The one distinction is 2 units of exterior stringers on the prime of the chines, at totally different ranges. It’s unknown why SpaceX put in these on the booster, because it’s the one booster that sports activities them.
Booster 16’s second companion, Ship 37, had an fascinating testing journey. The cryogenic proof checks went nominal at Masseys; nonetheless, the engine testing was fascinating to say the least. With the anomaly of Ship 36 and injury to Masseys, SpaceX had no option to static hearth ships till the whole lot was fastened.
So, as an alternative of ready, and in typical SpaceX style, groups fabricated a makeshift stand to combine with Pad 1 (A)’s launch mount.

This setup included a modified ship transport stand together with a makeshift ship umbilical that tapped into the booster fast disconnect traces. This was used to static hearth the ship twice: a single-engine static hearth and a six-engine static hearth. Nevertheless, crews needed to check Ship 37 once more with a spin prime as a consequence of swapping out a Raptor Vacuum engine.
As for adjustments, SpaceX has applied upgrades to forestall the problems that occurred on Ship 35 and Ship 36. These embrace strengthening the diffuser on the prime of the methane tank, which spreads the pressurization gasoline, in addition to bettering procedures concerning the dealing with and loading of COPVs. Externally, there are not any adjustments of word.

Mission Aims, Timeline, and Launch Home windows
The mission goals for Ship 37 are the identical as these of the final three ships which have flown. Get by way of ascent, have a managed coast part, carry out an in-space burn, try to deploy dummy Starlinks, and have a managed reentry. As a part of the reentry testing, SpaceX is as soon as once more attempting to check metallic tiles, an actively cooled tile, and tiles lacking in a number of places to emphasize check the ship.
SpaceX has not been capable of get any managed reentry information on Block 2 by way of three flights, so groups are hoping that the fourth time is the allure.
Timeline-wise, propellant loading of the ship is now 1 minute and 23 seconds longer; this could possibly be due to the change to COPV loading. The remainder of the timeline earlier than launch stays unchanged. As for post-launch, most instances are the identical with a one-second variation on some occasions.

The one vital distinction is that Booster 16 could have a lift again burn that’s 10 seconds longer in comparison with Flight 9. This period is about the identical as with Booster 13 when it accomplished its offshore divert throughout Flight 6. As for trajectory, this can as soon as once more be a suborbital ballistic trajectory with Ship 37 set to splashdown within the Indian Ocean.
Starship Flight 10 is presently set for no sooner than Aug 24 at 6:30 pm Central Daylight Time with a one-hour launch window. Cameron County has backup seashore closures that run from 11:00 am to 10:00 pm on Aug 25 and 26, and a lot of the notices have alternatives going into September.
So much is driving on this launch as SpaceX might use a win with ship testing earlier than all the Block 2 autos are flown. There is just one extra alternative to fly a Block 2 ship with Ship 38 on Flight 11, earlier than SpaceX transitions to Block 3.
