Woo! What is the debris?
it's not debris, it's something on the side of the barge

Oh hey salut les potes \o>
Nouveau Kerbonaute au rapport, je vais tacher de représenter dignement la recherche spatiale française, si j'arrive un jour à atteindre l'orbite et m'y stabliser.
il y a un début à tout ^^

If they do put a dragon on mars by 2018 or maybe 2020, it will only be useful as a demonstrator of powered landing on mars... There's no way a dragon will be used for a manned trip to mars, so the "red dragon" is probably not so much of a big deal

It also might depend on being in "astro/cosmonaut" shape. I think the Soyuz has had plenty of fairly hard landings (or at least off course) and that some US astronauts have experienced such.
Every soyuz landing is hard, by definition

How many astronauts are among people which can pay?So, until the fair price of such trip exceeds price of a mountain trip...
The astronauts actually get paid to fly

How do we estimate a random animal's limb mass (limb defined as any body part that attaches to the abdomen at only one attachment point, and be movable by the animal) with a given physical structure and average density?
Just put it in water to measure its volume, and then, if there is enough muscle on it, it's usually safe to assume that the density is 1.

To answer your subject line: No.
I can feel the debate progressing forwards

Yeah i could see some very cool uses for this, if we were able to transfer data in unmanned vessels, it would be possible to do sample-recovery missions hayabusa-style, where only a small shielded part comes back, holding all the data. This could also work very well if we could store the data in the probe core like @pthigrivi suggested

Yeah, a mini radial decoupler would be awesome.
4 hours ago, Angeltxilon said:It is a good idea.
The problem of the current radial decouplers to use in small probes is not the size of these decouplers, is the propulsion caused by decoupling. And sometimes this is problematic, because a accurate fly is required in satellites and similar.
Add small radial decouplers that does not cause nothing force of decoupling (a thing like magnetic decouplers) could be very useful.
You know you can set the ejection force on any decoupler from 0 to 100%, right ?

Because that's simply the magnitude of the maneuver vector.
Because it's a much more complex problem than you think.
You misunderstood me. I'm not saying "if it's possible to do it for manoeuvers then it can be done as easily for ships" , i know it's only a vector magnitude.
What i'm saying is that from a *gameplay* point of view it makes no sense to have this ∆v information without any way to know how much ∆v a ship has.
Also @zarakon
-
I don't understand how we can have a ∆v readout for manoeuver nodes and kspedia explaining what it is, and yet we can't know how much delta V our ship has. It makes literally no sense to me
EDIT : i'm talking about a gameplay point of view. Not about technical doability of a ∆v-meter. Gameplay wise, i think that this situation is just like having the pricetag but being unable to look how much money you've got in your wallet
-
... I don't see the point of doing this anyway. The stage *did* destroy the deck

I'm trying to quote @J.Random's quote here but it's not working and that quote up there won't go away... (That new forum though x_x )
Err...this comparaison is pretty much meaningless because it's not like the stage came down like a feather without any energy... It must have had A LOT of kinetic energy. The actual pressure equivalent was probably orders of magnitude higher than 22t/m²

My experience in metallurgical engineering is very limited, but I am extremely doubtful that the engine plume would significantly weaken the strength of the steel. There's just not enough time. It was probably energetic enough to blast off particles (like a sandblaster that is actually a flamethrower) but weakening the tensile strength of the metal is just not likely.
Obligatory "Jet fuel can't melt steel beams !"
On a more serious note i agree 100% with that, there's no way the plume (even if it's pure O2 oxidizer) could melt the barge in one or two seconds... The stage probably simply hit the barge hard

Most aerospace companies do this sort of testing in computer simulations. Only when the design is frozen, and when they are 100% confident, do they actually build a working prototype. You don't see Boeing or Airbus blowing stuff up to see if it works.
The A400M does crash during testing though
(I know it's not relevant, no need to start a thread war about this, it's just funny)

They'll never keep up to that schedule, it's way too much

Is there a live to watch somewhere ?

Fourth and final burn should be finishing now, 12 minutes 29 seconds after it began. However, due to the stage currently being over the Great Lakes and therefore over the horizon for Roscosmos' antennas, it will take a while to confirm the burn.
I'm really surprised that there's no way to relay signal from just the other side of the planet. Aren't there any antennas that can be used there ? Or a satellite network ? Pretty astonishing for me that they have to wait for the rotation of the earth to get that signal.

Also they mentioned - and we saw in the video - that the rocket is "free standing". I don't know if it has any physical link to the ground, but it's certainly a far cry from the complex clamp and support systems we see on many other launchers. I wonder why the Russians chose that approach - is it related to Proton's conception as an ICBM?
Maybe because it's fueled w/ hypergolics, it doesn't need an umbilical, and so it was all simpler to do without any launch clamps ? Just guessing

well, they had to rely on the images given by rocosmos
- Proton launches are way less mediatic than Soyuz ones - so they might not have the necessary equipments near the proton launchpad to transmit live 1080P streams Arianespace streams are much higher quality than what we had tonight
I'm afraid this is not true since the video on ROSCOSMOS's channel is in very good resolution
-
God the quality of ESA's video is afwul. Seriously this is 2016 and one of ESA's most important missions, and the video is only 45 seconds long and in 240p...
And then there's spaceX with 1080p stream even though it's a private company... This is pretty embarrassing

Dang it, i have a (boooring) biotech class during the launch
Looks cloudy anyway

Why do they roll it out so early ??

Fine, CONVENTIONAL rockets.
Apart from it's launch platform, the rocket itself is pretty much standard

How about replacing the merlin 1d with a Merlin 1e, using staged combustion instead of F9 FT? The RD-180 isp is ~30s higher for both Vaccum and surface, you could definitely get enough for the F9 FT performance without deep cryo- SpaceX already has experience on this from Raptor development (which is staged combustion) and Merlin 1e could give experience for MCT/Raptor.It's still not a dead end, like deep-dryo, either. The engine development would still be a pain, but SpaceX has been continually developing and improving the Merlins anyways. The rest of the tooling can also still remain the same. The engine development might be somewhat longer, but SpaceX isreally in no rush,as FT was made to increase performancefor land landings- SpaceX had almost nailed sea landings when V1.1 was retired.
This is interesting but again it's just a bunch of suppositions
