tater Posted July 10, 2018 Share Posted July 10, 2018 This is counter to this thread title, but interesting. It's also somethign that I think everyone expected (a point of DC is that it's launcher agnostic). Quote Link to comment Share on other sites More sharing options...

Those people aren't their customers. 9 hours ago, Scotius said: 18 meters mirror in space *twitches*. Can you imagine photos such beast will be able to take? To be honest we shouldn't send it to L1. We should sent it to the light focus point of the sun. All objects with mass bend light, so if you got far away enough, you could get to a point where the sun's gravity lensed light to, causing an enormous boost in magnification. To sent it out to 550(!) AU would take some creativity though. Quote Link to comment Share on other sites More sharing options...

Given how much effort they put into their PR, I'm guessing that they DO care. Maybe those people aren't directly their customers, but they have an influence on the people who are.

Not to mention the faceless bureaucrats who need to get re-elected/re-appointed who would need to authorize such an acquisition of nuclear materials by a private corporation. And they generally tend to listen to the loudest voices, not the most sensible ones... Quote Link to comment Share on other sites More sharing options...

People freaked out over launching a few kilos of plutonium for Curiosity, an air-breathing nukyaler rocket?!!!!?!!1!1! Ermagherd! They’re gonna irradiate the chemtrails and kill the vaccinated ozone! Think of the fish-children! Yeah, not even Prof Calculus was crazy enough to use a nuclear rocket for launching and landing, and this was back in 1953!

TBH, if I was to decide how that telescope should be build like I would go with mirrors like this: Instead of having dozens of origami folded smaller mirrors it would be better if each was as big as the cargo bay allows it to be. Should minimize complexity. Butmaybe once JWST is finished the tools and technology will already be in place to make the same kind of telescope but bigger.

StrandedonEarth Posted July 11, 2018 Share Posted July 11, 2018 I assume they’ve done stability analyses to make sure it won’t capsize under an off-center catch in an unfavourable wind? After all, it’s not rocket science, it’s marine science. Quote Link to comment Share on other sites More sharing options...
StarStreak2109 Posted July 11, 2018 Share Posted July 11, 2018 How heavy is a fairing half? Also I don't know what kind of special equipment the vessel has, like stabilizers etc... Quote Link to comment Share on other sites More sharing options...

cubinator Posted July 11, 2018 Share Posted July 11, 2018 Yeah, the fairing itself is fairly light, and the entire net structure seems to be fairly light compared to the boat. Remember that boats like this are fine: And Mr. Steven seems to have its weight a lot lower than that. Quote Link to comment Share on other sites More sharing options...

Anchors away!(for extra ballast) Quote Link to comment Share on other sites More sharing options...
tater Posted July 11, 2018 Share Posted July 11, 2018 The mass of the fairing is vastly lower than the ship, I’d wager that caught at the outside edge of the net it doesn’t even make Mr. Steven heel measurably. Quote Link to comment Share on other sites More sharing options...
magnemoe Posted July 11, 2018 Share Posted July 11, 2018 How do they capture two fairing halves? two boats once they nail it? Or an fast way to move the first out of the way like an zipper in the net. Quote Link to comment Share on other sites More sharing options...

Atlas V's shortest 5m fairing weighs 3500kg so I would guess that Falcon 9's fairing would weigh in the 1500kg-1700kg neighborhood per half. This is peanuts considering that Mr Steven's deadweight tonnage (which I had to look up what that was) is 510 t. Quote Link to comment Share on other sites More sharing options...

Plus if stability were an issue, you could increase it by using ballast, stabilizers and control moment gyroscopes... I believe SpaceX's engineers can do their math...
