No it’s not. And you’re trying to change the subject. You clearly don’t know what you’re talking about and you’re just shilling for SLS+Orion.

Er, are you aware I am talking about an abort system? The amount of fuel needed for an abort system is a completely different animal than what is needed for maneuvering. Who are you trying to fool?

Huh? Are you amightywind? This makes no sense.

“They [SpaceX] already backed off their really stupid “heavy” design and switched their focus to heavy lift engines and hydrogen upper stages.”

They have only offered glimpses into possible directions they could go for larger capacity launchers, and they have neither committed to a particular design, nor eliminated one of them. Can you substantiate your statement?

“Their pusher system, which loads the dragon with toxic propellant is not going to work.”

You make it sound like SpaceX engineers hadn’t researched pusher versus tractor designs & trade-offs before they decided to pursue the pusher design. Are YOU aware of how pusher LAS systems work, because it sounds like you’re making uninformed guesses…

“Dragon has a long long way to go before any tourist goes for a ride.”

It’s hard to tell what unit of measure you are basing this on – is “long” a year, and “long long” two?

As far as when Dragon will start carrying crew, it’s more likely that NASA personnel will be the first passengers, and the next will be researchers going to Bigelow space stations that their countries have leased (the sovereign nation business Bigelow has LOI’s from 6 countries for).

I don’t see tourists having a place to go in space for quite a while, so that part of your statement would probably be correct, but not for the reasons you think.

They may be crazy, but they’re not stupid.

Their pusher system, which loads the dragon with toxic propellant is not going to work.

They already have “toxic propellants” (hypergolic) in Dragon for ACS and orbit maneuvering.

Where do you get your misinformation? And why are you compelled to spread it around?

Er, are you aware that Orion uses the exact same toxic propellants?

You will also probably see a tower type abort system mentioned in their press releases. Their pusher system, which loads the dragon with toxic propellant is not going to work.

Dragon has a long long way to go before any tourist goes for a ride. I would predict the company going bankrupt long before it ever carries anyone. FWIW

Lisp hackers should be able to see through a flawed argument.
