High entry force & heat breached engine bay & center engine TVC failed

If we were to save more Delta V for the centre core landing, would the second stage have spare Delta V enough to complete the STP-2 mission? Cause then the core wouldn't have crash landed......I guess

Yes, but we couldn’t take a chance on 2nd stage failing it’s 4th maneuver. This mission was more complex than anything I’m aware of in history of rockets. RIP center core, you did your duty well.

Launch date is 2026They haven't picked a launcher yet for Dragonfly. It's not a given that it will ride on Falcon Heavy.
The first commercial mission for SpaceX’s Starship and Super Heavy launch system will likely take place in 2021, a company executive said June 26.
Jonathan Hofeller, SpaceX’s vice president of commercial sales, said the company is in talks with prospective customers for the first commercial launch of that system roughly two years from now.
“We are in discussions with three different customers as we speak right now to be that first mission,” Hofeller said at the APSAT conference here. “Those are all telecom companies.”
To call this an ambitious target date would be an understatement I feel.

i hope SpaceX more mature nowElon Musk in 2017 - "It actually ended up being way harder to do Falcon Heavy than we thought. ... Really way, way more difficult than we originally thought. We were pretty naive about that."
Im on the East coast of Florida for a little bit, so I had to make a pilgrimage to the "secret" #SpaceX Starship yard in Cocoa. Its big and shiny and unlike anything else anyone is planning to fly. pic.twitter.com/PybjNbVt3E

Partly due to Musk’s own involvement in the program, SpaceX’s propulsion development team have struggled to get any single Raptor engine to survive more than 50-100 seconds of cumulative test fires. According to information from sources familiar with the program, Musk has enforced an exceptionally hardware-rich development program for the first full-scale Raptor engines to such an extent that several have been destroyed so completely that they could barely be used to inform design optimization work. Although likely more strenuous and inefficient than it needed to be, the exceptionally hardware-rich test program appears to have begun to show fruit, with the sixth engine built (SN06) passing its first tests without exhibiting signs of a problem that has plagued most of the five Raptors that came before it.
SpaceX has been chewing through an average of one Raptor engine per month since February 2019 – by testing engines to destruction and aggressively comparing engineering expectations with observed behavior and post-test hardware conditions, rapid progress can (theoretically) be made.
Instead of spending another year or more analyzing models and testing subscale engines and components, SpaceX dove into integrated testing of a sort of minimum-viable-product Raptor design, accepting that the path to a flightworthy, finalized design would likely be paved with one or several dozen destroyed engines.
Between first development engine & first flight engine with operational payload, there are always hundreds of changes to both hardware & software. Over time, thousands.

Was the 50sec expected-Raptor SN6 test tonight considered a success, or was it intended to have been longer?

Overall successful. Aborted at T+51 sec on high mixture ratio, but we were intentionally probing the corners of the box of operating conditions, so not surprising.

Seems a very expensive approach this “hardware rich” approach where you’re literally chewing through full scale engines.

IIRC in the book V-2 by Walter Dornberger, that's just about how they developed the V-2, full scale launches. It would launch (or maybe not), explode, then they would try to figure out what failed --
Meh, the engines cost $1-2M apiece. Imagine doing this with entire rockets (as the Soviets did with the N-1).
There's a fire at SpaceX's East Coast Starship facility. Doesn't look too bad (no expert). Priority is all are safe. Emergency crews are on site.

I understand everyone is eager to learn of Raptor SN6’s status in McGregor... And where I would usually not post if as unsure of a test... There MAY have been a ~1 min test at ~9:50pm. It lacked usual Raptor strength, but perhaps was needed for greater duration. We shall see...🤞

To add to this: NASA says SpaceX can use a previously flown booster on this mission.

IXPE is a small satellite, but this launch contract is less than what NASA paid for for the still-pending Pegasus XL launch of ICON ($56.3M in a 2014 contract). Think about that… https://t.co/sJlWVMHC5c

Hmm...🤔Anyone out there interested in a *certain* rocket engine??! 😄🚀✨-You know, I can’t be certain until EM himself gives the confirmation (🤞@elonmusk🤞) But @ 8:41:11pm, there was a deep & powerful, rumbling roar heard from @SpaceX McGregor! 8:42:35 hard stop! #spacextests

Word is SN6 Raptor really stretched its legs tonight. And below is a local report confirming!

Almost time for Raptor to go to the Seaside again and for lots of us to be watching webcams muttering "Fire Truck leaving? VENTING! FLARE STACK! More venting. Ooh, big flare stack!" 😅 https://t.co/1YMRZOFvMT

Is there a secondary pad it will be aiming for or is it all just a continuation of the main pad?

Sure
Local amateur photographer and spaceflight fan Michael Tapes has graciously shared a new aerial view of SpaceX’s Florida Starship facility, where dozens of workers can be seen buzzing around what is hoped to become the first orbital-class prototype of the massive spaceship and upper stage.
Tapes’ aerial footage offers a unique look at the layout of SpaceX’s Florida site as of July 9th, illustrating just how active and expansive it is. Some workers can be seen building something (perhaps preparing a new worksite) under a large, white tent, while another group surveys two large Starship segments and a third works to prepare new stainless steel ring sections. Of note, those two large Starship segments appear to be bereft of any obvious activity, perhaps a consequence of a fire that caused about $100,000 in damage the day prior (July 8th).

Rumour is that there'll be a static / tethered fire (of the Starship Hopper) test on Monday 2pm, followed by another static or just an untethered flight of the Starship Hopper at 2pm on Tuesday.

Will SpaceX be televising the event? Or will it be behind closed doors.
