There is no ablation at 400°C to 800°C, which can be achieved by forming the 'lifting body' more into the direction of larger wingspans, instead of making it falling fast like a brick. Which hasn't been done so far, because larger wingspans are impractical for rocket lift from earth, but that doesn't apply here.
