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



Tesla FSD just saved two lives on the highway. A man walked straight into traffic in heavy fog/rain at 65+ mph. The Model 3 spotted him and swerved safely. Could’ve been fatal for both the pedestrian and my cousin driving. Insane reaction time. Grateful for @elonmusk @Tesla















"There are 140 laws in South Africa that basically give strong preference to if you are a black South African and not otherwise. Starlink is not allowed to operate in South Africa, because I’m not black." 一 Elon Musk
