Mars Direct

Space Exploration, the Red Planet, and the Human Future

De: Robert Zubrin

Narrado por: Erik Synnestvedt

The human race is at a crossroads. In the coming years, we will make decisions regarding our human spaceflight program that will lead to one of two familiar futures: the open universe of Star Trek, where we allow ourselves the opportunity to spread our wings and attempt to flourish as an interplanetary species - or the closed, dystopian, and ultimately self-destructive world of Soylent Green. If we ever hope to live in the future that is the former scenario, our first stepping stone must be a manned mission to Mars.

Dr. Robert Zubrin details the challenges of a manned Earth-to-Mars mission. Challenges which, according to Zubrin, we are technologically more prepared to overcome than the obstacles of the missions to the moon of the sixties and seventies. Dr. Zubrin's relatively simple plan, called Mars Direct, could feasibly have humans on the surface of Mars within a decade. Zubrin also discusses the current predicament of NASA, the promise of privatized space flight from companies like SpaceX, and the larger implication behind the absolute necessity to open the final frontier to humanity - the human race's future as a species that takes the necessary baby steps away from the cradle that is planet Earth or, ultimately, perishes here.

Reseñas de la Crítica

"Bob Zubrin really, nearly alone, changed our thinking on this issue." (Carl Sagan, The Denver Post)

Choppy

Book s basically 4 parts: Mars Direct, Private Enterprise, Risk/Safety and Philosophy. Would have been better if the other 3 pieces were interspersed into the Mars Direct story. An update would be nice too, a lot has happened since 2016.

Not what i thought it was going to be..

I thought this was going to be a short work on what is listed in the title, space exploration, Mars and the future. Instead the majority of the work is basically complaining about the current administration's handling of the space program and NASA itself. The first thirty minutes were exceptional, full of visions of the future and travelling to Mars, exactly what i expected. From there, it derails and talks about why even planning Mars Direct isn't possible now or in the next three years. That's not to say that the information provided isn't accurate or interesting, but if you're looking for something full of theories on space travel/colonization (besides "change the government!"), look elsewhere.

Enlightening

Combines science, exploration, hope and humanity into a how-to book on forwarding the human race.

Persuasive Case for Mars Direct Approach

Sorry to say US may not shoot for Mars as it shot for the Moon, but it should. Would love to see HRC reshape NASA mission focus and risk taking. Thankfully groups like Space X are helping to point the way and demonstrate feasibility.

Excellent & Concise

Very good, concise analysis of current state of US space exploration programs, focusing on Mars. Want to hear more on this and similar topics. Well narrated.

Great look at why we're not on Mars

“I have no desire to do a Mars landing on our own… The U.S. cannot always be the leader, but we can be the inspirational leader through international cooperation.”

Those were the words of Obama's NASA chief Charles Bolden when asked about the agencies vision for landing humans on Mars in 2012.

That quote was amazingly NOT in the book which is surprising since it pretty much sums up the current administrations view on anything to do with space, manned or not. To put it another way if your kid says they want to be an astronaut you should first start by getting them Russian language classes.

To the other reviewer that is offended that the author of the book would dare to criticize Obama for cancelling Americas manned space program maybe you should spend less time reading bumper stickers and more time actually paying attention to the issues if you actually care space travel.

The book is broken down into a few sections and it started off a bit slow but it hits its groove pretty quickly, which is a must in such a short book.

The author wants to get Americans (or humans in general) to Mars and points out how it could be done NOW, and paints a very reasonable picture of how to do it. In fact a lot of what he talks about is what SpaceX just announced with its plan to send humans to Mars and back in 2018 (to orbit, not land on the planet).

The author also takes a very harsh, and needed, look at the current administrations' complete lack of vision with NASA which apparently is offensive to people that value politics over space exploration and scientific achievement.

Overall the book was a very good short read and the reader did a good job and was completely appropriate for the subject matter.

If you're interested in realistic ways that people can walk on Mars in the near future this book explains it. If you're wondering why we have to fly our astronauts to Russia to get them to the ISS - you'll understand why, and why it's not going to change in the near future.

#saveoppy

In a time where partisanship is so rampant war is suggested, space is survival.

An angry critisism of NASA and Obama

Is there anything you would change about this book?

I was hoping for a book about colonizing Mars. About 1/3 is devoted to excoriating NASA. The first 1/3 is about a plan for getting to Mars efficiently and I was glad to hear it. But the rest: meh.

Do you think Mars Direct needs a follow-up book? Why or why not?

Mr Zubrin sounds more like right wing ideologue than a scientist.

Interesting Mars info, needless political talk

Zubrin's short book provides a reasonable outline of Mars mission technical details. That's about half of the book. The other half is a rambling and unloading of his political gripes and opinions. If you can tune that out, it is interesting. I wouldn't want to be cooped up with him on a ship to Mars though.

How to get there now

This quick read details how we can use today's technology to begin colonizing Mars within the decade. Zubrin rightly criticizes the current bureaucracy encumbered and politically driven NASA approach. But his complaints have the purpose of showing how the NASA that gave us the moon, could refocus and make Mars possible. The current direction will take 60 years. The goal is to get there as soon as we can.
