Kudos to SpaceX for Flight 13

After a last-second automatic abort on the 16th,  and a bad weather delay Thursday,  SpaceX was able to launch its Starship/Superheavy vehicle successfully on Friday (24 July 2026).  This was Flight 13,  called by some “Lucky 13”,  the second flight for the new version 3 vehicle,  which is bigger,  and uses a new,  upgraded version of the rocket engines. 

Unlike the previous test flight,  nearly everything about this flight appeared to work perfectly.  Kudos to SpaceX for a job very well done!  Very well indeed!

The upper stage Starship vehicle flew perfectly,  with all its engines working,  and re-lighting just fine.  It deployed some 20 examples of the latest version Starlink satellites,  performed the in-space re-light of an engine (which proved not possible on the previous Flight 12),  re-entered the lower atmosphere without any problems over the Indian Ocean near Australia,  descended to low altitude,  re-ignited its engines,  made its flip to nose-up,  and a very soft splashdown landing in the sea.  

It even survived toppling over into the water without exploding!  So,  it might even be towed to Australia for direct inspection,  a real bonus for evaluating the heat shield performance!

The Superheavy booster flew most of its intended flight plan quite well,  excepting the final touchdown burn into the sea,  just off the SpaceX launch site near Brownsville,  Texas.  The “hot staging” seemed to work fine,  with 3 of the 33 booster engines keeping the propellants settled in free fall,  inside the tanks during its flip-around,  so that 13 engines could be ignited to perform the boost-back burn. 

This failed on Flight 12,  due to multiple lost engines,  but it worked just fine this time on “Lucky 13”.  There was something wrong about that Flight 12 flip-around maneuver,  which may have in some way induced those failures-to-ignite.  It occurred in the wrong plane,  for one thing,  according to reports.

The coasting booster then arced over,  back toward the launch site,  and fell into the lower atmosphere,  stabilized tail-first by its grid fins,  toward a low altitude touch-down burn event.  This last burn is where the trouble happened!  Instead of igniting the intended 13 engines to slow down its very supersonic speed,  a handful of engines failed to ignite!  The booster descended stably,  but did not decelerate adequately on too-few engines,  and so it struck the sea at something still near the speed of sound!  That intended soft booster splashdown was the only failed objective in this entire test flight,  as near as I can tell.

We did not see quite so many engine ignition failures in the version 2 Starship/Superheavy test flights that happened before Flight 12 (which was the very first version-3 flight).  Something is going on with version 3 that will have to be found and fixed,  before SpaceX can risk attempting to catch the booster with the arms on the launch tower.  They did that catch  successfully more than once,  with version 2 in the earlier flights.  A truly spectacular thing to watch,  too!

But a failure to decelerate to a slow hover would end up destroying both the booster and the launch-and-catch tower!  And right now,  there is only one of those facilities in existence that is compatible with the version 3 booster!  They have to solve this engine ignition problem with version 3,  before they risk attempting another booster catch.

The upper stage Starship is another story entirely,  now after its complete success during “Lucky 13”,  and near-complete success during Flight 12!  It would be a reasonable bet that they might attempt a ship catch,  on the next flight.  Musk himself even hints at that,  on social media. If they do attempt this feat,  that would be the very first recovery of a Starship that has been into space at near-orbital speeds.  Such would be invaluable,  both for heat shield evaluations and improvements,  and for eventually demonstrating the readiness of this vehicle to actually do real orbital missions.

There will be tension within SpaceX over this.  Some will want to see another Starship upper stage water landing success,  before risking the catch facility.  Others will want to forge ahead as fast as possible.  That is normal.  We will soon hear what they decide to do next. 

I wish them success,  especially since doing spaceflight successfully,  really is a very,  very hard thing for any outfit to do.  And once again,  kudos to SpaceX for a flight test that was almost entirely successful!
