Agent Smith had it right
"Never send a human to do a machine's job."
I'd love to see NASA put more money into new science, using robotic sample returns, rovers, etc.
NASA is bumping its robotic mission to the moon in favor of a rescheduled Endeavour launch on Wednesday. The US space agency said today the human-staffed excursion to the International Space Station will take priority June 17 over the launch of NASA's unmanned Lunar Reconnaissance Orbiter (LRO) and Lunar Crater Observation and …
Any bets this will come back to Rocketdyne flogging NASA the engines and pipework after they acceptance tested it with liquid Nitrogen?
Much safer but roughly 10x higher viscosity (NIST data base numbers at boiling point) of Hydrogen and 4x the BP. Astonishingly (to Rocketdyne) it seems joints and structures tested with Nitrogen are not quite so leak tight when Hydrogen flows through them.
who';d have thought it.
"This is your driver speaking. I'm afraid there's a bit of traffic on the taxiway out to the pad today. I've spoken to launch control about a slot and they're getting back to me. In the meantime, we're number 12 in the queue and, assuming nothing changes, we should be in position to blast off sometime after hell freezes over."
The robotic missions are being launched on Delta and Centaur rockets?! Why are they leaving from Canaveral, then?
The Air Force routinely launched military missions from Colorado. White Sands has capability as a backup launch site in case Canaveral had a "catastrophic" failure to rescue manned missions.
Why were these *much* smaller rockets even considered for Canaveral when the ever-delayed Shuttle was due to launch within the same week?!
