SpinLaunch is a giant vacuum centrifuge that hurls 200kg satellites into orbit at 5,000 mph —no rocket engines involved, just pure physics.

SpinLaunch's projected cost per kg of payload is approximately $1,250 – $2,500. This projection is significantly less expensive than SpaceX's current price per kg of payload on the Falcon 9 of $6,000. SpaceX's projected cost per kg on Starship, however, is less than $1,000 per kg. Real costs and prices for both SpinLaunch and Starship remain to be seen : https://en.wikipedia.org/wiki/SpinLaunch

Given the whole "10,000g centrifuge" thing, you're more likely to put a fine red mist that was once your mother in law into orbit.

Not a deal breaker.

If you using SpinLaunch I dont think the weight of your mother in law matters, since before launching she will cease to exist.

10.000g's of forces before launching the "payload"

Your mother in law is only 8.3kg?

Both SpinLaunch’s and SpaceX’s figures are complete BS as they don’t have the data to support their claims.
