Let's say I'm returning home in my near-future space capsule, but instead of the leisurely Mach 32 the Apollo astronauts experienced striking the atmosphere, through major [plot-device hand-wavium] interference, I re-enter at Mach 172.

**What would happen?**

I'm guessing I'm instantly vaporized. But what else? Is earth doomed as well?

Edit: Capsule specifics  

Let's say my re-entry craft is about 6 meters in diameter and 4 meters tall in the classic gumdrop shape of Apollo era space capsules, with a weight of 10,000 kilograms.

My ablative shielding was designed to withstand up to 20km/s reentry speeds, but is recommended to only re-enter up to 16km/s.
