Just getting to Mars faster is only half the battle. Once there, it's necessary to decelerate. The faster the approach, the longer the slow-down. Some of the Mars landers have had to make multiple elliptical orbits, barely skimming Mars' thin atmosphere on each pass, in order to slow down enough to initiate the landing sequence. The process often takes months. It's not an insurmountable problem (other issues relating to human health and safety are far more vexing), but it does prove, once again, that there's no such thing as a free lunch.

Why do we need to send humans to other planets? Why not send robotic missions (also sample return missions)? I am not sure what astronauts will accomplish which robotic landers cannot? The desire to have a human foot-print on the surface of another planet though exciting is not really worth the cost, risk and what could be achieved by undertaking such a mission.

Moon and Mars, that's it. Mars we could, but will we? not sure at all anymore. Probably not.

What will make it worth the cost is the potential for profit. The one thing humans can possibly do on other planets that robots cannot is live, inhabit, colonize, and reproduce there.

I believe that we need a commitment to expand human presence out into the solar system, if not only to perpetuate the species.

That will be up to whatever society actually does it.

I hope they know how to do a cost/benefit analysis.

Yeah... It's kind of annoyig that people in 5 or 6000 years will look at our civilization as primitave and barbaric, just as we often do the ancient Egyptians.

Not annoying to me. We really are still barbaric, in a number of ways.

I do hope we grow out of it.

I'm sure they will. But it will be under their individual definitions of costs and benefits, not ours. These equations do change, and drastically, as technologies, opportunities, circumstances and priorities evolve. What was once a cost might later be seen as a benefit, and vice versa.

I'm relatively confident that at some time in our future history, assuming the big IF we survive the next few generations, living among the asteroids and comets will be calculated as having more benefits than costs.

Will we ever go to another planet?

Considering our collective ruination of this planet, I sincerely hope not.

Had a conversation with my cousin recently. I said yes to this question. He was adamant that we (humans) would not. Can't go faster than light... blah... blah... blah...

I thought "what a ridiculous viewpoint he has."

200 years ago two cousins were having the same conversation about using a rocket to get to the moon. One said it would happen. The other said it would not, and well... we see how that turned out.




In the future we will have no choice. Earth won't be habitable forever. When that time comes we either move or
go extinct.

If we put all our planetary resources and technical skill into the endeavor, I am willing to bet we could build a generational starship that could span the gulf to the next nearest solar system.




I can think of some people whom it would be worth the cost to put aboard such an "intergenerational" spaceship and send them far, far, away to never personally return. Whether most of the people I have in mind would actually want to go...that's beside the point.

That's what the dinosaurs did. Knowing that the Earth was about to be impacted by an errant asteroid, a few of them built a generational ship and headed for the stars -- some place in the constellation Draco, I think. Of course, those of them that stayed behind, the really unimaginative and short-sighted ones, didn't fare so well.

Thinking that such activity would represent salvation for the human race in the face of imminent destruction might prompt me to begin searching the heavens for the constellation Hubris (the asterism resembles a big pie in the sky).

You doubt human ingenuity. We could poison the atmosphere beyond reclamation or let runaway greenhouse effect take over...but humanity will build retreats and survive. No different than building a self-contained spaceship.

Of course, these 'specialized' redoubts will no doubt fail to hold the entire population of planet Earth so some thinning of the herd is inevitable.
