Starship Flight 4 in about 2 weeks.

Primary goal is getting through max reentry heating.

Worth noting that no one has ever succeeded in creating a fully reusable heat shield. Shuttle required >6 months of rework.

SpaceX might exceed 90% of all Earth payload to orbit later this year.

Once Starship is launching at high rate, probably >99%. Has to be or we can’t build a city on Mars or base on moon.

We file almost no patents, so nothing stopping competition from copying us.

SpaceX Fixing Starship to Reach Rapid Reusability

SpaceX will try to launch on June 5, 2024 if they get FAA approval. Elon and SpaceX are communicating the June 5th date as if the FAA is close to giving the launch license.

Here is what has been learned and fixed after the third flight.

Super Heavy Booster:
• Second successful ascent.
• Initiated boostback burn; 13 engines started successfully, but six shut down early due to filter blockage.
• Attempted landing burn with only seven engines starting; contact lost at 462 meters altitude.

Identified issue: Filter blockage in liquid oxygen supply.
• Fix: Adding hardware in oxygen tanks for better filtration which will increase startup reliability of Raptor engines.
