* Internal fuel pipe lowered down from the top, through the upper tank. This pipe is about 40-50 cm in diameter and some 10-12 meters long. It has three big holes at the bottom side part, I guess to connect to the engines. Will probably be connected to the bottom of the upper fuel (liquid methane) tank. It will pass through the liquid Oxigan tank.

Hahaha,...they removed the fuel pipe again.
Probably to change some things, or it was a fitting test of some kind...

* Starship SN1 tank preparing for Raptor (engines) attachment, pressure testing and static firing.

Elon Musk:
* SN2 tank integration begins this week with much less circumferential pucker... (had to search that one up... if I am alright, it means with less dents, wrinkles or bends in the body... Correct me if I am wrong.)
* We had the wrong (welding) settings! [...]. Having the right settings is a major improvement.

* They will also use a planisher to make the weldings more flat.
* SN2 will get 3 Raptor engines. Most likely SN1 will not fly, but do a static firing only. Because 1 or 2 Raptors will not be enough to lift it properly.

Monday 02-03-2020

* On feb 28, 2020, SN1 desintegrated with two loud "bangs", at cryogenic pressure testing (liquid oxygen in the lower tank). The entire section of about 25-30 meters high, went 25 meters high up into the air, destroying the entire bottom section, doing so, after which it fell down and was totally destroyed. After hitting the ground, the upper tank section (probably filled with liquid nitrogen N2), which was still intact, exploded and sent the bulkhead away as if it where a canon ball...

* The remaining parts of SN1 are rapidly being removed from the test stand at Boca Chica.
* Vertical flip of a (SN2?) dome tank section, in the VAB-1 windbreaker. (VAB=Vertical Assembly Building).
It looked as if one of the turning motors was stuck halfway, but after some mechanics took care of it, it turned for the full 180 degrees.
* The front side of VAB-2 is plated. The roof is completly on it.
* The 3rd Garlic Tent has now three trusses upright, with the roofing on it. Previously, they first put all trusses in place and than put the roofing on it.

Correction: the vertical flip is done in VAB-2!
Wow! Huh!?
The building is not even completed! ...That is a quick use or it!

* New tent for ring manufacturing already had 6 beams on Tuesday/Wednesday. Now on Thursday, 10 beams have been placed. It is really getting form. Roof sheeting is done directly. The side (bottom) supports of the tent are placed on top of two containers in height, probably to get more height for rocket pieces inside.
* Engine section, in the VAB-2 gets some sort of thrust ring on it. Also a Bulkhead piece is placed in the VAB-2.
* VAB-2 construction (plating) still ongoing. One side almost closed.

Thursday 19-03-2020

* VAB-2 gets its last left wall done with sheeting.
* SN3 stacking begins in VAB-2.

Elon Musk: Super heavy and Starship evolves: slight booster length increase to 70m, so 120m for whole system, Liftoff mass ~5000 metric tons. Design is evolving rapidly. Would be great to flatten domes, embed engines & add ~1.5 barrel sections of propellant for same total length. Also current legs are a bit too small.

* Raptor Ser.No.20 did a test firing of about 5 seconds.
* Some fire at the launch pad (insulation?) was extinguished with the new water fire extinguishing system. Seems to be controlled from some distance. Also one of the lower dump valves (the dumped propellant) caught fire after the test.
Nothing serious I believe.

* One nosecone has been dismantled. It was probably a testmodel, a bad construction, or an outdated construction.
* The second lift system in VAB2 seems to be finished. The the rail system reaches to the top now.
* The second and new spider leg building has almost got al its sheeting and roofing done.
* A new half round shaped tent is being constructed at the building facility.
* More concrete poured to enlarge the landing pad for the 1st SN4 test flight. It is about 100-150 meters away from the test stand.
* SN4 is repaired. There were some minor damages from the fire after the Raptor20 firing test.
* SN4 has got a construction on top of it. It is a cube shape, together wit a round shape with two large pipes in it...? Seems to be some sort of mass simulator.
* SN6 engine section is stacked together (thrust puck/dome/rings).

* SN4 with Raptor No20 had a static fire on its launchpad for 6 seconds.
* Huge flares from burning off Methane were visible.

* SN4 had another static fire test. After the test a large rupture of some kind in the propellant line or in the lower part of the tank occurred. A massive explosion was the result. SN4 totally destroyed. Much damage to test stand.

* SN4 fully removed from the test stand / launch pad.
* Test stand SN4 disassembled.
* Work continues on 2nd test stand.
The Wilscott building roof, next to test stand of SN4, got ruptured by a large metal beam from the explosion.
* The structure to protect the fuel lines was fully blown away from the concrete slab and landed upside down.
* SN6 top section seems to be ready and is set aside VAB2. Later on it was stacked to SN6.
* SN6 section in Vab 2 is now 10 rings high. Only the engine section is missing.
* SN5 still waiting in the left side of VAB2 (Vertical Assembly Building).
* A 5 ring stack is also in front of the VAB2. Possibly the cargo section which comes below the nose cone(?).
* SN7 top section (tank bulkhead) is under construction. It got its sleeve mounted.

* The new test stand has been equipped with a new quick disconnect box, for disconnecting fuel and Oxygen lines from the Starship. That is where it went wrong with SN4. The quick disconnect test failed and Methane and Oxygen got mixed and at the proper mixing rate detonated, destroying SN4 and the test stand.
* SN5 probably rolled out to the test stand on monday next week.
* First SN5 tank filling and static fire will be on the schedule.
* Hydrolic actuators for pushing upon the aft end of SN5 to test Raptor thrust against the aft end, are installed on the new test stand.

* SN5 rolled out of the VAB.
* Engine section for SN6 rolled into the VAB, on the left side.
* SN6 (tank section) still in the VAB, on the right side.
* SN6 stacking, engine section and tank section will soon begin.

* SN7 test tank, different stainless steel alloy(304L), transported to the test stand. Cryogenic tests have begun and ended. A leak occurred on top of the tank with lots of fuming cryogenic gas. The pressure test reached 7.6 Bar. Elon Musk: the goal was, to push it to failure. There are a few known weak points on this SN7 test tank, probably capable of more pressure. The second test tank to follow shortly has addressed the weak points. Tank didn’t burst, but leaked at 7.6 bar. This is a good result & supports idea of 304L stainless being better than 301. We are developing our own alloy to take this even further. Leak before burst is highly desirable.

* Today, SN6 stacked (engine and tanks section) in the VAB.
* Work on the new Starship test stand commences.
* At the test site, deep holes are drilled (20+meters) for concrete foundation. I guess it will be for a test stand, or launch stand, for the complete stacked Starship, so, Super Heavy rocket booster and Starship itself. It will be immense high and have a lot of weight when fully fueled.
* Raptor engine production is on SN30 at this moment. Elon Musk: propellant enters Raptor chamber as hot gas thats already mixed. Throttling is done by adjusting flow to the ox and fuel preburners. The lower limit of thrust is ox & fuel turbopump injector preburner stiffness. This essentially means: when do the preburner elements start flaming out.
* A new VAB will be build, for supporting the Super Heavy booster. It will be somewhere around 80 meters tall.

* Starship SN5 and SN6 now both nearing completion in the VAB.
* SN7 test tank is undergoing repairs for further testing. Follow up test tank wi8ll soon be ready.
* The foundation holes for the Super Heavy rocket booster test stand are filled with concrete.

* SN5 moved to and lifted onto the test stand.
* SN5 hydrolic actuators/rams for testing engine pressure during testing, are mounted under SN5.
* SN5 had a succesfull cryogenic pressure test. Fully filled. SN5 entirely covered in frosty ice...
* SN5 hydrolic actuators/rams for testing removed again.
* Next probably a Raptor engine will be installed for hot fire testing.
* Bluezilla Rises! Super Heavy High Bay Builder Crane. It can lift 600 tonnes and has a reach of about 185 meters!
* Another new nose cone appaers outside the fabrication tent (was previously inside).
