Via NSF.

SpaceX - Falcon Heavy - Arabsat 6A - 4K - High Fidelity - by Epic visual and sound production by Jay L. DeShetler for NSF. Headphones on and enjoy "tower clear" with the big rocket and her 27 Merlin 1D pals.

From Musk Twitter:

Quote
Thinking about adding giant stainless steel dragon wings to Starship


Later quote said he was 6.5 out of 10 serious.  As usual, we'll have to wait to figure out what he really means.

Probably just a cheeky Game of Thrones reference, although you may never know.

And for some extra lulz, see below...  ;)

With Musk its hard to tell when he's joking.  He added this:

Quote
With steel membrane wings like a Dragon, we may be able to lower Starship’s orbital reentry temp to ~1000 degrees C, which would allow the whole surface to be uncooled bare metal


Offhand, I would not be surprised if there is another design update. Putting these comments into a Game Of Thrones thread really adds another layer of uncertainty.

Bad news... due to rough seas, it sounds like the center core of #falconheavy tipped over [emoji30] they do have a robot named “octagrabber” that can hold down F9’s but unfortunately it can’t hold down the center core [emoji17] at least they stuck the landing and proved the system works.

Not that I think he ever saw it but I DID tweet to him that he should name the first Starship, "Galileo".   ;D

I think we need some kind of a protocol for such hazardous content.

SpaceX loses the center core of its Falcon Heavy rocket due to choppy seas

Quote
“Over the weekend, due to rough sea conditions, SpaceX’s recovery team was unable to secure the center core booster for its return trip to Port Canaveral,” SpaceX said in a statement to The Verge. “As conditions worsened with eight to ten foot swells, the booster began to shift and ultimately was unable to remain upright. While we had hoped to bring the booster back intact, the safety of our team always takes precedence. We do not expect future missions to be impacted.”

I understand that due to his ultimate goal to colonize Mars and avoid duplication of effort, Musk chose a VTVL architecture for all of his launch and space vehicles, but those are the perils of foregoing wings and landing strips on firm ground.

The landing was ~1000 miles out in the ocean. What do you get when you create a vehicle with a 30-ton payload and wings capable of 1000 miles of crossrange gliding? The Space Shuttle, and we all know how cheap that turned out to be.

SpaceX have a solution in place (the 'Roomba' robotic vehicle that parks under the landed stage and grabs it to stabilize it), but that vehicle wasn't yet modified to handle the FH center core.

Whereas the perils of going with wings and landing strips might mean not being able to do it at all.
