Do you believe the Orion program will work?

>> No.10468139

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

>> No.10469624

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.

Hey guys!!! Guys!!! Listen, let's.... guys, listen... lets use solid fuel boosters on a manned launch vehicle!!!!! Guys!!!!!!!!

>> No.10469821


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

>> No.10469847

Which liquid fuel?

>> No.10469854

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.

>> No.10469876

Not sure if retarded or pretending.

>> No.10469884

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

>> No.10469896

Performance, vibrations, noise, cost?

>> No.10470076


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.

>> No.10470274

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