Why doesn’t the capsule burn up on re-entry?

    Capsules come in through the Earth’s atmosphere at a great velocity. They get very hot as they pass through the atmosphere. They have a special shield called an ‘aeroshell’ which protects the sensitive samples from the heat of re-entry. The shield is made from ‘ablative’ material whose surface vapourises as it travels through the atmosphere.
