Elon gave his estimate of the odds at 1/3. What say you?

Why Spacex’s Next Rocket Test Will (Probably) End in Flames

Next week, Spacex’s latest Starship prototype is going to attempt a test flight t hat CEO Elon Musk says it has only a one in three chance of survival. In all probability, Starship will end up in a fiery grave. While this launch test is crucial to the development of the Starship rocket, its “success” or “failure” is not. Here is what can go wrong and why it may not matter anyway.

The Starship rocket is Spacex’s next generation launch vehicle intended to replace the Falcon 9/Falcon Heavy. Starship will be largest rocket ever built, even larger than the Saturn V rocket that took humans to the Moon. Unlike the Saturn V, however, Starship intends to be fully reusable, with both the first and second stages returning to Earth.

What is this Test About?

The Starship prototype that will be flying next week is the 8th iteration and known as “SN8” or Serial Number 8. SN8 is the upper stage of the full Starship rocket. The upper stage will return from orbit much like the Space Shuttle did, reentering the atmosphere on its side, where the surface area is greatest, with a large heat shield taking the brunt of reentry heat.

Unlike the Space Shuttle, however, Starship does not have proper wings or landing gear. Instead, Starship will land vertically using the same engines that propelled it into the heavens. In order to land vertically, however, the craft must reorient itself from falling on its side to falling bottom first….and this will be no easy feat.

Nailed the Return approach, landed on target. Looks like an Engine failure caused landing at to high a velocity, causing the destruction of the ship. All in all, a productive flight. I'm sure a lot was learned for the next flight to prove successful.

I’m just glad no one was onboard.
