SpaceX Launches, Landings and News

Seriously. Jesus christ. That transfer stage looks to be close to a thousand tons or more. And it's going to launch twice in one day. Seriously, immediately refuel and relaunch with a new, denser refueling stage. All that punching to Mars at... christ, I don't even-

This is straight up-I... no, this is insane! This is insane, and glorious, and holy shit it's actually happening!

Addendum: Seriously, christ, 2 and a half weeks to Mars!?!

The speed of the transporter at earth departure is to be 62,000 mph. This is almost double the speed of the previous record holder, New Horizons, which was a very small, light probe launched by a large rocket, resulting in its unusually high departure speed of 36,000 mph. In an ideal transfer window, New Horizons, if it had been aimed at Mars, could have reached it in about 40 days. The MCT, at 62,000 mph, should be able to get there in about 3 weeks.
 
So want this to work. But also understand that 99% of these things fall flat on their face, never seeing the world.

Hoping this is one of the few that succeeds.
 
Man I want details so badly! Concept looks solid, but there are a few points where I wonder how they'll be addressed:
  • The mid air flip towards a propulsive landing. I can imagine it working in martian atmosphere, q is low enough to pull that off. But I worry how they'll do it upon earth return. It'd have to be aerodynamically unstable, or have some dumpable ballast weights to shift COM
  • How do the interiors look? If the door is as high as implied, I wonder how the astronauts are supposed to get down to the ground. Let alone cargo.
  • 1 refueling mission. That's gonna give some very tight margins. I believe that r/spacex calculated that 3 would be the likely number of refuel missions. Maybe they just omitted the repeats for the concept video?
Can't wait to get into the nitty gritty once the speech starts!

Dragon 2 will apparently have a weighted sled on tracks to control the COM during reentry. Wouldn't be surprised if they did the same on this.
 
Sweet mother of God.

500 tons to low earth orbit.

In comparison, the best SLS can come up with is 140 tons, according to the ArsTechnica journalist I'm talking to right now.

Edit: He mentioned 80 days to Mars.... wow.

My only worry is that AMOS-6 has tarnished their launch reputation, and hence they won't be able to sustain their launches or their R&D.

That Q&A session was literally cancer. I'm sorry... but there was no way to describe that.

You ask to come up on stage to kiss Elon? WHY?

I'm saving up for my ticket; I don't want to live on this planet anymore.

:B

"Hey Elon, I don't care about your rocket ship, but can you give me some free PR by looking at my swag electric bus?" Like, seriously? Where did they get these people?

I hope he does a press conference later on with some actual competent reporters. I want more details on the return infrastructure on the martian side. I also want to know what the big spherical tank inside the 1st stage methane tank is for. Can't be COPV since they're using the fuel itself as pressurant. Maybe the TEA-TEB storage? Though I have no idea why you'd store that at cryo temperatures.

To paraphrase Miyazaki:



At this point, the /r/SpaceX sub is debating holding their own conference in the IRC. It was... bad.

And yeah, I hope we get more details on the infrastructure to Mars. $200,000 to get to Mars makes me HYPE.
 
I want this to happen but I am not putting a bet on it. The price per day to be on a trip to mars would have to be only an order of magnitude more than the price per day for a trip to antarctica to hit his target.

I want to believe, but I'm still remaining rational about this. If they get funded by NASA though, we're probably going to see a colony real soon.
 
The booster has 42 engines. 42.

The big spherical tank shows up inside both of the spacecraft's main tanks as well:



And they clearly have feed lines to the engines. I'd guess they're tanks specifically for landing propellant to avoid having it slosh around in the cavernous main tanks. The booster doesn't have one in the oxidizer tank, but it does have that obnoxiously huge feed line running down the center of the fuel tank. I bet that line's big enough to contain all the oxygen needed for landing...

I'd hate to be the poor bastard writing the environmental impact report for that. 9,200 tons of liquid methane and oxygen (booster and tanker) means that any pad or early launch failure has the potential to rival Hiroshima and Nagasaki in scale.

Aside from the issues with financing it, I don't see them ever getting the regulatory approval to fly such a monster.

Thing is, they're already building the test components of the initial hull. They're already close to finalized designs on the craft, and already have the initial components built. Wait, I already told you this on SB!

Seriously, this is basically 'who cares if it might blow up, we pay dollars per kilo!' territory. So cheap that it doesn't matter that there is any possible risk at all, because you're going to be paying $50k for an average-sized sat on a properly reused booster. And if SpaceX fails, they've got the blueprints laid out for Bezos to take up the torch.

Seriously:


*Checks* Ah, with the tanker stated cargo capacity of 380 tons of fuel to the parking orbit, it's $9 dollars per kilo to LEO.

Let's do a little comparison of current launch costs, shall we?

Payload mass delivered to LEO Cost per payload kilogram
Long March 3B (China)
13.6 metric tons $4,412/kg
Zenit 2 (Ukraine) 13.7 metric tons $3,093/kg
Zenit 3SL (Sea Launch) 15.9 metric tons $16,190/kg
Ariane 5G (ESA) 18 metric tons $9,167/kg
Proton-M (Russia) 20 metric tons $4,302/kg
Space Shuttle (NASA) 28.8 metric tons $10,416/kg
Saturn V (NASA) 118 metric tons ??
Falcon 9 v1.1 (SpaceX) 13.15 metric tons $4,654/kg
Falcon Heavy (SpaceX) 53 metric tons $1,700/kg

For the promise of literally cutting millions of dollars off the cost to LEO, yeah, anybody in any frame of mind is basically going to 'TAKE MY LOVE, MY HATE, AND ALL OF MY MONEY' at SpaceX for this beautiful bastard.

I'd hate to be the poor bastard writing the environmental impact report for that. 9,200 tons of liquid methane and oxygen (booster and tanker) means that any pad or early launch failure has the potential to rival Hiroshima and Nagasaki in scale.

Basically, as pointed out by the above comparison, it would be a strategic asset for the US to have this monster, as it would make space infrastructure pocket change. $2500 for a person to orbit (land anywhere in the world!), the possibility of orbital solar power on the cheap at long last, literally ALL the probes on a single launch, useful payloads to the moon...

And with this kind of money, Musk could go 'well, why don't I just build myself the mother of all barges and float my big beautiful bastard out into the middle of the pacific if you're so damn worried about it' if regulatory approval for launches from the US isn't a thing.

Well, they did launch the first Falcon 1s from a Pacific island, and there's nothing more supervillain than launching a giant rocket from your remote island base...
