I don't think we should gamble our human space flight program on a single rocket. Having multiple separate development programs sounds like a good idea.

- pstuart 4y agoAgreed. While I'd like to see NASA do it right, I'd settle for a couple more companies giving SpaceX real competition. Blue Origin and Virgin Galactic do not appear to be those companies.
- Yizahi 4y agoThe problem is that SLS is inherently unsafe for humans. Much more so than any possible alternative, real or paper rockets included. Almost all those money left for actual engineering probably were spent on duct taping this monstrosity to be even a little acceptable for human rated flight.
- sashahrzg 4y agoSource on it being unsafe for human flight?
- Yizahi 4y agoThe most obvious factor can be observed by any amateur at the SLS photo - it looks like two long white thingies strapped to the sides of the rocket :) . Joking aside - Space Shuttle was deemed about as safe as 1 in 60 flights by two different commissions. This SLS uses exact same hardware in general, and can't be much safer than an inherently unsafe Shuttle. That's unfortunate fact of life. I sincerely hope that no crew would be harmed flying this thing.
