It is really interesting to see that this is a very &#x27;ordinary&#x27; commercial geostationary launch customer, and not a government funded research satellite. This is oversimplified, but traditionally, rockets that are in beta test mode are tested like:<p>1) static pad tests&#x2F;firings of engines<p>2) all-up launch of the full rocket, carrying a boilerplate satellite with some instrumentation, maybe some cubesats or low cost small R&amp;D satellites tagging along<p>3) one or two launches of government science payloads, or government-funded weather satellites, something like that<p>4) commercial launches begin

I wonder if they&#x27;ll really save money right away doing this. I imagine they&#x27;ll spend a lot on inspections and getting things 100% right.<p>Either way, it&#x27;s an amazing achievement.

So knowing nothing about this subject, why do they pursue landing rockets, or at least landing them vertically? It seems like the hardest possible way to handle this problem, as opposed to for example what the shuttles did. Can anyone explain the reasoning behind this?

Hopefully someone can support&#x2F;refute this: my off the cuff guess why this happened is because the discount on the launch price is about equal to the cost of building the satellite. So if it works, everyone is happy. If it explodes, they can build another one and aren&#x27;t out any money (but are out time), and the launch costs for the next one are covered by SpaceX or insurance - however they have it set up.

Whenever see a news about SpaceX it gives me goosbumps. I hope it will land successfully again.

Just wanted to say that the phrase &quot;flight-proven&quot; is genius marketing.
