>>13075178
SpaceX has modified their sats to be drastically less reflective, and almost undetectable when fully in orbit.
Your poor attempt at trolling may have held some merit almost a year ago when Starlink first started getting launched, but even astronomers are happy with the darker revisions. Hence why you don't hear many people crying about it anymore.

starlink launches are actually some of the heaviest recoverable F9 launches out there. 15.6 tons. For comparison a Crew dragon with trunk is ~13 tons. (metric)

Note that on DM-2 the total payload was around 18 tons due to food rations

The booster is off-course intentionally and only corrects at the last moment. If something goes wrong with the booster, it wont hit the droneship.

Sorry that’s what I meant, falcon 9 can’t hover due to the t/w ratio
>>
>>13076177
>>13076189
I was thinking they had repainted the X but that was just the legs. Yeah, they stopped repainting it because they kept nailing it.
>>
>>13076180
Additionally to what others said, the 1st stage still has some horizontal velocity when starting the landing burn, so it's normal the booster is not aligned with the droneship
>>
>>13076230

...New Glenn actualy exists?
>>
>>13076226
>>13076194
also on land they programmed in various buildings. so even if it goes off course with limited control somehow, it will do its darnedest to not blow up the VAB

I was skeptical about the super heavy catching plan Elon proposed but after seeing almost every F9 hit dead center on the drone ship it doesn't seem as crazy anymore
>>
>>13076282
I was thinking the same thing.
>>
>>13076282
From what I understand, all falcons are connected to a main computer which learns from each and every landing. The first landing attempts were shit but as they tried it more and more the computer was able to compensate for new parameters. That's why it gets dead center these days. Again I'm not completely certain but I'm pretty sure this is how they do it, so I suspect SH will be the same once they try and start landing it

Blue literally chose the most expensive way of building stages (isogrid). They brought this upon themselves.
