Elon Musk indicates that the SpaceX Starhopper has been damaged after being toppled in 50 mile-per-hour winds. This will take a few weeks to repair.

I just heard. 50 mph winds broke the mooring blocks late last night & fairing was blown over. Will take a few weeks to repair.January 23, 2019
Elon Musk had mentioned in a tweet on January 5, 2019, that unexpected issues could delay the Starhopper by 4 weeks. This turned out to be an accurate prediction of bad weather causing damage and delays.
Aiming for 4 weeks, which probably means 8 weeks, due to unforeseen issuesJanuary 5, 2019
Elon Musk explained in a Popular Mechanics interview that 300 series of stainless steel alloy can handle higher temperatures than carbon fiber or aluminum. Carbon fiber can theoretically take higher temperatures but in practice, the resin has problems after exposure to prolonged temperatures over 300 degrees Fahrenheit.
~1750K is peak heating expected on about 20% of Starship for LEO entry, ~1600K on 20%. Rest drops below 1450K, so no heat shield needed. Radiative cooling at T^4 takes care of 60% of the ship. Another reason for steel.January 23, 2019
The new metal rocket design will use some water and fuel to help cool parts of the rocket. Overall the new metal design will be lighter, stronger and lower cost. A huge benefit is the new design should massively reduce the development time for the new rocket.
It will be very interesting to see if SpaceX and Elon Musk are proven to be right again about their design choices. Will SpaceX complete a fully reusable rocket with 100 ton or more cargo capacity in less than four years?
Yeah it's crazy that stainless steel is close to surviving reentry heat without cooling!!! There's stainless steel upper stages that survived reentry even! It almost seems obvious now. Super cool.December 25, 2018
