Said structures are operating in a thermal environment which is already challenging to begin with though, so there might not be a lot of margin to bear additional heat load. The straw which breaks the camel's back...

I do agree about the optical challenges imposed by hypersonic flow past the target - lasers currently seem to have quite enough problems dealing with normal atmospheric distortion and turbulence.

It's definitely a risk doing this kind of work out in the open, but at least it's ultimately just relatively cheap steel and can be built again from scratch in a couple of weeks.

Or hammered out.  ;)

NASA would be folding up the tent by now.

Or they wouldn't have built it out in the open in the first place...

Because they would have built a billion dollar building first.

I wonder why the move to a wider span swept wing (trailing edge included) instead of the N156's trapezoidal type.  Higher aspect ratio and wing area for the same leading edge sweep angle and wing root area?  Seems like they wanted a boost in lift efficiency without having to rely on such large drag inducing LERX.

The nosecone of the starship hopper has blown over in strong winds & been damaged. Mr Musk states it will take a few weeks to repair. However, the business end of the hopper is fine.

Unfortunately a storm has toppled the (separated) top-half of Starhopper, damaging it quite a bit. On the plus side it's not as important as the bottom half of the rocket, but this will obviously set things back probably a couple of weeks, unless they decide to omit certain test objectives and just carry on with a half-sized Starhopper.

Edit: Also a couple of tweets from Elon about it:

I just heard. 50 mph winds broke the mooring blocks late last night & fairing was blown over. Will take a few weeks to repair.

Actual tanks are fine

How long until the first hopper test. What do you think?
Aiming for 4 weeks, which probably means 8 weeks, due to unforeseen issues
