Re: Manned Dragon

I am surprised by this. One more delay caused by a total overhaul? To get a launch escape system ready, it's not enough to build a helicopter for landing on Mars, you need to remake your entire capsule too. I am grateful they are busy throwing out the "when it ain't broke, don't fix it" principle out of the window, we need less of it to really get into space. And there was I, ready to hitch a ride on the Dragon V1 with no extra life support, no launch escape system or seats, let alone tablets.

I never thought that a capsule could look appealing to the eye. By going back to rockets and capsules, I was beginning to think that practical space exploration is going to look ugly.

And Spaceflight with printed engines? Didn't expect that.

(Don't remember to ship one of them DMLS printers to Mars one day)

Perhaps the "Cycling Spacecraft" would be closer to the mark..

Well, pretty much all they really have in common is that both are phallus shaped. The Orion was supposed to be nuclear powered IIRC and the wings on the Hydra are really solar panels
I understand the "wings" on the Hydra/MCT are solar panels. I simply meant the rendering reminded me of renderings of the Orion shuttle from the movie 2001: A SPACE ODYSSEY.



As for being nuclear, that is not mentioned in the movie, nor is the name Orion. All of that appeared in the model kit and other behind-the-scenes material.

One must also be careful when dropping the name "Orion" in regard to spacecraft, as NASA has one in development, and Dyson's proposal was definitely nuclear powered.

But, it's a two-edged sword, because who could control an unanswerable CEO, if she/he gets lured to the "dark side"?
You're right. No government would ever run amok. It's always those foaming-at-the-mouth CEOs.

Personally, I don't understand what the difference is between a mission to the Moon and a mission to Mars, other than distance and duration.
As Sojourner already noted, the relationship between planets is dynamic. Even if we ignore that for a minute, how does a space station somewhere in between help? The station needs to be routinely supplied; it's not another Earth that is independent. Roadside inns don't work in spaceflight.

Perhaps you are suggesting some sort of supply convoy, which has been addressed in many studies. A fleet of ships might be sent, or a supply vessel might be sent on ahead to wait at Mars, or even be intercepted along the way as part of a complex navigation scheme.

Creating a Moon colony first has many advantages. It is much closer, affording the possibility of an abort back to Earth if anything catastrophic happens. The proximity also means there are potential financial returns, while Mars is just too far away with current technology. And there's the experience factor. Long duration missions on the Moon, or even a permanent colony could be very valuable in testing various survival technologies.
