SpaceX has rolled out Ship 30 to finish its engine testing marketing campaign and has accomplished Booster 13’s cryogenic proof testing. In the meantime, upgrades and preparations proceed forward of Flight 4, which may occur by the top of Could.
Ship 30 Engine Testing
Ship 30, which is slated to fly on Flight 5 with Booster 12, has been rolled out to Suborbital Pad B to start its engine take a look at marketing campaign. For this testing, it’s anticipated that Ship 30 will carry out the identical checks as Ship 29: a Spin Prime, six-engine Static hearth, and a single-engine static hearth. There are highway closures for this testing which can be from 8am to 8pm CDT on Could 7, 8, and 9.
Notably, Ship 30 rolled out with engine covers, the primary for a ship. The primary Booster to try this was Booster 10, which skipped a Spin Prime. Now, with the mix of utilizing the brand new enclosed engine set up stand and having engine covers, SpaceX might begin skipping spin primes on ships.

With Ship 30 on the pad, a couple of adjustments have been seen. First, two new roll thrusters have been added simply above the ahead dome. These are subsequent to the brand new radio antenna, which is an improve over Ship 29 and replaces the six tile-like antennas that was on the nosecone.
One other fascinating addition is a brand new Liquid Oxygen (LOX) vent on the prime of the LOX tank. This vent appears to be like to have a sensor with some sense strains going into the tank and possibly a brand new strain reduction valve.
Masseys and Booster 13
Booster 13 was rolled out to Masseys for cryo-proofing after being absolutely stacked on Feb. 2nd, 2024.
Throughout the rollout, SpaceX confirmed off the brand new booster cap for boosters and not using a Scorching Stage Ring. This cover will assist maintain out water and contaminants whereas the car is exterior the Bay. Together with the cap, Booster 13 additionally had grid fin covers, because it has not acquired its grid fins but.
Some fascinating issues to notice about Booster 13 are that it has two new LOX vents, one on either side; these look like the identical kind that has appeared on Ship. Booster 13 additionally already has the brand new giant baffles put in on the engine part, similar to Booster 10 had.
As soon as at Masseys, Booster 13 accomplished two cryo-proof checks: one full Methane tank and one full LOX tank. These are the identical checks that Booster 11 and Booster 12 acquired at Masseys and appear to be the plan for boosters going ahead. As soon as these have been accomplished, Booster 13 was rolled again to Mega Bay 1 and positioned on the middle work stand.

SpaceX continues working onerous to arrange the brand new Ship static hearth stand. All the items of the flame bucket have been lifted into the ditch for set up. Venting has been occurring from the brand new Methane tank farm, so SpaceX could also be fairly near getting this new take a look at stand operational.
With all these milestones, Ship 30 could possibly be the ultimate ship to static hearth on Pad B, which might finish an period. However it will even be the start of SpaceX simplifying testing to 1 space away from the place there might be two Orbital Launch Pads.
Orbital Launch Pad 2
SpaceX has gone full steam forward with groundwork for the second Orbital Launch Pad at Starbase, beginning with putting in piling and rebar cages. These will assist help and safe the various constructions groups will construct over the following 18 to 24 months.
SpaceX has stuffed within the land simply in entrance of the Gateway to Mars signal to enhance entry to this web site for heavy equipment and a staging space.

A portion of the wall that that signal is on has additionally been destroyed to permit entry in order that heavy equipment doesn’t must undergo the launch web site entrance. That is solely the beginning of what’s a really lengthy strategy of constructing a full orbital launch pad.
Orbital Launch Website Adjustments
After months of pipework to hook within the new 9 horizontal tanks, SpaceX has now examined and begun filling them with LOX and Liquid Nitrogen (LN2). With these operational, SpaceX now not wants the vertical tanks, and to go along with that, the entire welds for the Cryo Shell lifting factors have been inspected earlier than being eliminated.

Thus far, SpaceX has began eradicating the perlite from one of many LN2 tanks and is setting as much as do the identical to the second LN2 and the three LOX tanks. Now, SpaceX might solely take away a minimum of yet another tank earlier than Flight 4, however by Flight 5, the entire unique vertical tanks is perhaps gone.
Persevering with with upgrades to the Launch Website, SpaceX has upgraded the left chopstick arm with a brand new and upgraded actuator to permit for the next movement fee into the actuator. This, together with SpaceX both upgrading or growing the output of the chopstick hydraulic system, has drastically elevated the velocity of the arm for opening and shutting.
Together with a sooner arm SpaceX has been including conduit for the wiring and including padding again on the sticks forward of a possible booster catch on Flight 5.

Flight 4 Preparations
In preparation for Flight 4 and hopefully a faster pad turnaround time between Flight 4 and 5 SpaceX has upgraded the linkages that assist transfer the hold-down arms out and in of the internal Orbital Launch Mount (OLM) ring.
Groups have additionally put in a brand new set of clamps on the hold-down arms, which they’ve executed prior to every flight up to now.
Different preparations for Flight 4 embody a brand new Booster Fast Disconnect (QD) Hood, which has a modified design and doubtless a greater seal to attempt to shield the principle cryogenic provide strains going into the QD. The Ship QD acquired a set of additional insulation wrap on its essential provide hoses, and SpaceX just lately accomplished a full retraction take a look at.

The most important milestone forward of a potential Moist Costume Rehearsal (WDR) over the approaching weeks was SpaceX spinning up the Orbital Tank Farm (OTF) and spending a whole day purging the strains and performing operational checks. Normally, this implies SpaceX has accomplished the required work for the Orbital Launch Pad cryogenic methods and will quickly be prepared for a WDR or flight.
Booster 11 remains to be in Mega Bay 1, having acquired its Scorching Stage Ring, which signifies that it is able to go to the launch web site.
Nevertheless the launch web site should want some work forward of Booster 11 being mounted on the OLM, so SpaceX is maintaining the booster in Mega Bay 1 till groups are prepared. Nevertheless there are two 12am to 3am closures on Could 7 and eight which can point out a rollout of both Booster 11, Ship 29, or each automobiles.

SpaceX has been working onerous on Booster 11’s different half, Ship 29, with plenty of warmth defend work. This work is being executed due to classes realized with how you can connect tiles and since groups need to give this ship the absolute best likelihood of constructing it by way of reentry. Ought to Ship 29 make it by way of reentry, it will be a big milestone early in this system.
If SpaceX rolls out each Flight 4 automobiles this week, a WDR could also be deliberate shortly after. Even when SpaceX can full a WDR quickly, there may be nonetheless no information on when Flight 3’s mishap investigation might be accomplished. As soon as that’s executed, Flight 4 is probably not far-off.
