Do you believe the Orion program will work?

[Anonymous No.10468139]

Aren't they trying to kill it? I don't think it will

Orion (the capsule) will work. Who cares whether SLS (the launcher) will work, it is just a jobs program. Nobody in power seriously cares whether it actually launches.

The distributed launch proposal on commercial launchers is far more pragmatic. Launch Orion and the support module separately on smaller, existing, well-tested launchers and dock them in orbit.

SRBs are cheap, liquid fuel is not

also: see the USAF's various experiments on it going back to the X-15 and ZLL programs, easy to see why they would use solid fuel because it's so much easier to manage

Which liquid fuel?

[Anonymous No.10469854]

>>10469821
Liquid fuel is very cheap. Certainly more so than SRB. It is just a more refined gasoline / natural gas, for fucks sake. Not more than a few % of launch cost is the cost of propellants.

Not sure if retarded or pretending.

I never understood this meme, what makes SRBs unsuited to manned launches?

[Anonymous No.10469896]

Performance, vibrations, noise, cost?

SRB's are just oversized fireworks - they are uncontrollable once started and cannot be shutdown when something bad happens, unlike liquid engines. There's a reason why Russians use liquid fuel boosters - and they had no spaceflight fatalities in almost 50 years.

They explode in a cloud of napalm, making it hard to survive even if you can abort the launch.
