> Not sure how much cheaper SpaceX launches are for comparable payloads and orbits. I'd suspect they are, with e.g. Ariane developed for other thongs than LEO launches.

The direct competitor to SpaceX is the Space Launch System [0], with a cost of over two billion per launch. SpaceX charges below 100M$ [1] (and has cheaper options available [2]) and you can actually buy it right now (EDIT: although it's true that Ariane is in the same ballpark).

> If Starlink is actually sustainable and profitable has to be seen, it could as well just be a way to push SpaceX profitabiliy further down the road through a Starlink IPO. Now way to tell either way.

Whether a business can survive in the long term is never 100%. Still, you, as an average consumer, can order a satellite dish and get fast and mostly reliable internet for a reasonable-ish price right now. I'd say that checks as delivered.

You forgot Ariane Space. And the 100 million ballpark numbet is for Ariane 5, a rocket initially developed for a European shuttle program and not commercial, cheap satelite launches.

Edit: Starlonk is cheaper than alternative satelite provoders. Whether or not this is selling dollars for cents is the question, one that cannot be answered by Starlonk's existence itself.

SLS is a new rocket and you are comparing its development cost to the launch cost of a SpaceX rocket without its R&D cost.

Ariane V, delta, and soyuz launches are all cheaper per kilogram than SpaceX.

Look on Wikipedia, the sideboard quotes cost per launch as:

> Over US$2 billion excluding development (estimate)

I'm not aware of the pricing of Soyuz and Ariane V, though.

Both of which are much more SpaceX alternatives than SLS.
