They are probably making more money if that's the case. Less, but still more than the actual cost of the flight, so they still make a significant profit on every launch while being the cheapest provider on the market.

NSEP Posted June 24, 2018 Share Posted June 24, 2018 5 hours ago, Wjolcz said: I wonder what happens with LOP-G once people start flying on BFR. IIRC it will have a similar living volume to ISS and LOP-G will be smaller. So if BFR is operational they could use it instead. They can probably turn the entire BFS into a web workshop, wouldn't that be cool? Does the BFB also function as SSTO? If so, we can probably make a big space hotel out of it.

They are probably making more money if that's the case. Dragon missions are covered under the CRS contract for a number of flights / amount of cargo. So I don't think NASA got a discount on used boosters or capsules. SpaceX gets more profit to plow back into R&D and BFS Quote Link to comment Share on other sites More sharing options...

Elthy Posted June 26, 2018 Share Posted June 26, 2018 The landing looks realy smooth, but maybe thats just the camera orientation... Quote Link to comment Share on other sites More sharing options...

I was just thinking that looked pretty rough on the back. Probably preferable to dying horribly, tho. Probably. That chute opening seems pretty complex, too, I wonder how they control the different “stages” of the mains opening? Quote Link to comment Share on other sites More sharing options...

When the chutes are first deployed they are reefed in, and then when you hit your target altitude they fully deploy. 20 minutes ago, sh1pman said: With propulsive landing, hopefully! That seems unlikely. I doubt if it is being designed for both propulsive and parachute landing depending on whether it has cargo or crew on board.

cubinator Posted June 26, 2018 Share Posted June 26, 2018 Why can't they just land the capsule in the desert every time? Seems like it works well enough, and makes it way easier to reuse the capsule. Also, what's the heat shield made of? Is it ablative? Quote Link to comment Share on other sites More sharing options...

And the descent looks gentle, but I'd guess it's not as gentle as it looks, those things are deceptively huge. The parachutes were mounted off-center which would cushion a water landing, but a land landing like that would damage at least that corner significantly.

There’s a reason Soyuz uses retrorockets and Vostok bailed out... Apollo could make a land landing in an emergency, too, but much like the D2 here, risk of injury to the crew was extremely high. But better than dying horribly. Probably. 14 minutes ago, cubinator said: Just land it on a big pillow That’s exactly what Boeing is doing.

Mitchz95 Posted June 26, 2018 Share Posted June 26, 2018 I remember Chris Hadfield describing a Soyuz landing as "fifteen explosions followed by a car crash". They are not for the faint of heart. Quote Link to comment Share on other sites More sharing options...

Wjolcz Posted June 27, 2018 Share Posted June 27, 2018 (edited) 35 minutes ago, Cassel said: what about landing with engines? The fuel and exhaust products are too toxic. Edit: from Wikipedia: "On 24 July 1975, NTO poisoning affected three U.S. astronauts on the final descent to Earth after the Apollo-Soyuz Test Projectflight. This was due to a switch accidentally left in the wrong position, which allowed the attitude control thrusters to fire after the cabin fresh air intake was opened, allowing NTO fumes to enter the cabin. One crew member lost consciousness during descent. Upon landing, the crew was hospitalized for five days for chemical-induced pneumonia and edema." NTO is what Dragon 2 will be using. I'd imagine it will be for in-space manouvering and LES only. Edited June 27, 2018 by Wjolcz Quote Link to comment Share on other sites More sharing options...
