A Reusuable Sea Launched Two Stage? Better Than Spacex?
Beccab replied to Spacescifi's topic in Science & Spaceflight
This way it is identical to what Starship is planned to do, only that you need some massive ocean carrier with a nuclear reactor on board, are limited by the fuel and the upper stages that can fit on the carrier and have no real benefit from launching from the sea -
A Reusuable Sea Launched Two Stage? Better Than Spacex?
Beccab replied to Spacescifi's topic in Science & Spaceflight
But you do need infrastructure. Unless you want to launch ocean water and unfortunate fishes to space/an enemy country, you need to bring there the payload and most likely an upper stage too -
A Reusuable Sea Launched Two Stage? Better Than Spacex?
Beccab replied to Spacescifi's topic in Science & Spaceflight
Again, why would it do that? Is there literally any advantage that justifies carrying a nuclear reactor on board with all the related weight and high risks? -
There is hardly any parallax on RGV's pics, they are taken from so far and so zoomed in that they look basically ortographic

A Reusuable Sea Launched Two Stage? Better Than Spacex?
Beccab replied to Spacescifi's topic in Science & Spaceflight
What should be the advantage with that? Refuelling normally from a tank works just fine, and doesn't require carrying the weight of the machinery of separating LOX and LH from the ocean -
I honestly hope it will, Nauka is having a lot of problems right now with parts that, afaik, are necessary for a successful docking

The structural parts were speculated by the daily 3d models guy to be part of a stabilization system, i.e. placed vertically on the tower and Starship connects to that before stacking for precision, but who knows!

They even use stock solar panels -
What's the point of reaching the karman line if you can't show a cool pic of how astonishingly different it is from 86 km up?
-
Aw, no separation, internal cam, shots from around the capsule or from the boosters? Shame

Section 8 is split into two parts, this one (8A) that is 2/3 as high as a normal section and soon 8B which is 1/3 we high as a normal section

I actually had no idea what that stage was, I thought it was some titan derived upper stage at first but nothing seemed to fit (the 1.5 m upper stages were single engine and the 1.875m ones didn't work since in the drawing it's evident that the size reduces between the launcher and the pyewacket's upper stage), so I just went with a random tank and engines plus, it has plenty of fuel either way so it should be fine. As for the spacecraft, it is completely custom: the outer lenticular area are 5m flat connectors from NFLV, the central piece is a tantares heat shield, the cockpit an X-33 one clipped in; the connector is from the X-20; horizontal stabilizers from OPT; vertical stabilizers from BDB and with OPT control surfaces. The satellite interceptor is probably just as messy, but recreating that is easy with BDB and tantares. This mess is less noticeable only thanks to conformal decals, it looks much nicer with all those colours as well as the heat shield painted black. Using the text decal making the letters as wide as possible and activating the bold the whole thing becomes black, giving you rectangles of all colours and dimensions to apply on a craft. I did this on the upper stage as well, it is a normal BDB Titan tank with the stripes and yellow sections painted on it this way

Minimum and maximum altitude for Earth orbit
Beccab replied to MetricKerbalist's topic in Science & Spaceflight
Well, to quote the page you posted: It is only unofficially and presumably to reduce complications that the karman line is usually used there. If it was closer to 83 km, like it will probably be changed to in the near future, it would still be used in the same way -
Evac notice sent to Mary Edit: Closure cancelled, the date slips to tomorrow

"What does the 'S' stand for?" "It's not an S, on my planet it is a structural reinforcement"

It's made to support crew for 21 days, not three. Not comparable to a 6 months trip to mars, but it isn't a short time either
-
That's possible the least meaningful comparison that can be done. Orion is going to store 4-6 people for deep space missions on a volume that is less than 40 times smaller than starship. I'm not saying it will end up with 100 people on it, but the ISS has nothing to do with the reasons

Starship is actually known to be planned to have proper medical system on it https://boards.greenhouse.io/spacex/jobs/5305733002?gh_jid=5305733002
