We need heat shields to protect us, since we use the air to slow us down as we return to Earth. From orbital speed, it gets to 1650°C / 3000°F. From the Moon: 2750°C / 5000°F. For yesterday's Starship suborbital test flight, peak was 1450°C / 2600°F. Great to see the @SpaceX progress over the last 3 flights. Making them truly reusable is complex and necessary for permanent, cheap space access. image compilation: @niccruzpatane
