Could Orion take astronauts to Mars? Technically, yes. But they'll be dead in 20 days when life support runs out. Which is non-optimal.

@RocketAcademy Yes, #Orion could take people all the way to the surface of Mars, just not in one piece.

@Rand_Simberg @RocketAcademy Hey, it's your book that says we should stop obsessing over not killing people.

@kchangnyt That's different than sending them on a suicide mission. They'd be guaranteed dead three weeks from earth. @RocketAcademy

Point of the book is that we have to rationally match risk/cost to reward, not deliberately slam folks into Mars. @kchangnyt @RocketAcademy

@SafeNotAnOption @RocketAcademy Pair Orion with a @BigelowSpace module and do an Inspiration Mars flight, which you liked, I believe.

@kchangnyt Why waste all that money, when you could do it with a Dragon? @RocketAcademy @BigelowSpace

@SafeNotAnOption @RocketAcademy @BigelowSpace That's different from saying #Orion to Mars is "guaranteed dead."
