Review: The Martian

I was both pleased and disappointed, as always, when I heard that a book I enjoyed was being made into a movie. Andy Weir's The Martian was the best new book I'd read in years. It was written for nerds, by a nerd — by somebody with an obvious love for NASA, science, and spaceflight. How could it possibly be condensed into the format of a Hollywood blockbuster? Well, director Ridley Scott and screenwriter Drew Goddard figured out how. The Martian is an excellent film, well worth watching. Read on for my review (very minor spoilers only), and feel free to share your own in the comments.

Let's briefly discuss the book, first. If you haven't read it, I recommend doing so. In short: near-future astronaut Mark Watney gets stranded on the surface of Mars, and must figure out how to stay alive using only the limited resources at hand. This is hard science fiction. Weir meticulously researched all the problems facing Watney, without giving him magically advanced technology to defeat them.

The story is largely told through Watney's journal updates, which read remarkably like following a brilliant engineer's blog while he solves fascinating problems. Weir also infuses Watney with dry humor and an unwillingness to be told that the right way is wrong. For being so dense with science and engineering, the book manages to have a rapid pace.

Fortunately, that pace made the transition to film a bit easier, as did the book's narrative form. Watney's thought processes tend to be spoken, rather than a typical internal monologue, and this keeps it more conversational and brief. In the novel, when Watney has to "do the math" — for example to figure out the hydrogen levels in his living space — you follow along as he actually does the math, then as he develops a procedure to safely lower those levels. The movie tackles this complex scene by making him discover the problem right when it begins, with a small amount of hydrogen igniting dramatically. It keeps the science and the problem-solving, but conveys it quickly and moves on.

That's the real triumph of this movie's creators — they accelerate the plot while maintaining the book's love and respect for science and for thoughtful engineering. They embellish for interesting visuals, like the martian wind, and for dramatic license. But they never go over the top. It's... refreshing, to say the least.

One thing the film does even better than the book is bringing intensity to particular scenes. It's one thing to read Watney's account of how he dealt with an emergency in past tense — it's another to see it as it's happening. The first scene of Watney alone on Mars is incredibly tense and visceral.

This is largely due to Matt Damon's performance as Watney (and to Ridley Scott, for enabling that performance). Damon does a great job coming off not as a movie superhero, but as a funny, capable guy you might run into at your local makerspace. The other roles in the film are well cast and performed, too. Jeff Daniels as the director of NASA is the closest the movie gets to having a 'bad guy.'

He's the one who tends to raise the practical and ethical questions surrounding Watney's predicament. How many resources should be allocated to helping a single man? What will be the cost to future missions if they don't? They're impossible questions to answer, but they deserved to be brought up and debated.

One of the big reasons to see this film is for its cinematography. If you're a space buff, you'll really enjoy the long, lingering shots of the Martian surface. The graphic artists really deserve commendation. They make the landscape look both desolate and fascinating. They had lots of source material to work with from all the rovers and orbiters we've sent to Mars, and they used it to fill each scene with incredible detail. Look carefully and you'll see one of Mars's lumpy moons in the background of a shot on the surface, or a dust storm slowly flowing across a vast mesa when looking down from orbit.

The Martian, much like Apollo 13 twenty years ago, inspires us to cheer on our civilization's brightest scientists and engineers to solve hideously complex problems. NASA has been falling all over itself to help promote the film, and for good reason. I think the reception of this film will show support is still there from the general public to go and do really challenging missions. The Martian the best movie I've seen all year, and I highly recommend it.

      Corporations provide the majority of the jobs that everyone else works. When you raise taxes on corporations, the investors in the corporation don't suddenly decide to give up their income to pay for it, instead the companies shed jobs to compensate. So raising taxes on corporations causes less jobs, which causes less tax income.

      Now, back on the subject:

      I enjoyed the movie, my 15 year old now wants to read the book after watching it. As someone that went into the movie knowing everything that happens (they cut some scenes, but there wasn't very much material added), I was able to watch my parents and kids watch the movie. It was interesting to see how tense they became at many scenes, it was so good that it had my kids on the edge of their seats (literally) at many times. They did some things very well, but some of the explanations of why things happened were missing. For instance (SPOILER) they never explained why his launch ended up being too low and too slow, they just dealt with it. Also (SPOILER) the scene where he is reacting the hydrazine to produce water, he blows himself up, then goes back to the camera and says he forgot to account for the air he exhaled, next scene they show him doing it again with a space suit on, then later he walks around the area without the space suit as if the same problem didn't even exist. In the book it was excess Hydrogen getting around the flame and he detected it due to excess Oxygen in the room.

      Overall, I loved the movie, I watched it in the theater, and will buy the collectors edition version when it comes out.

      Private pensions are required to be fully funded at all times. That means that as soon as a person retires the company will have paid out all expected expenses for his pension. He's no longer a liability. However, the formula applied by government regulators for "fully funded" is relatively conservative to account for short-term drops in the market.

      That means that on the average day in the cycle of the stock market, a pension is slightly _over_ funded. In the 1980s this cash flow became the target of accountants and CFOs looking to make their quarterly profits look better, and in turn improve executive bonuses. The solution was two-fold: 1) switch new employees over to 401(k)s and 2) use corporate mergers, which provided a window to cash out pensions. And you got even better payouts if you merged and cashed out excess pension funds at the height of a stock market cycle. The payouts were booked as one-time earnings, and bonuses aren't usually fixed to where earnings come from.

      Another big reason corporate executives like 401(k)s is that it allows them to provide themselves more tax deferred compensation in greater disproportion to their regular staff. Federal law requires as a general matter that any benefits provided to executives are also given to all full-time employees. Under both a defined-benefit (i.e. pension) and defined-contribution (e.g. 401(k)) plans, the contribution to the retirement fund is a percentage of an employee's salary. For a host of reasons, in practice executives are able to give themselves a more disproportionate share of corporate earnings through 401(k) plans than through pension plans.

      Private pensions are a better deal in the long-term for employees. They don't actually cost companies more money. Cashing out pensions contributed substantially to earnings for about 20 years, but it was a shell game and really provided no long-term earnings gains; it was just a slow-motion transfer of billions of dollars of wealth from staff to executives and investors. 401(k)s permit companies to increase manager and executive compensation at the expense of staff in a way that's not possible with pensions. The only good thing about 401(k)s is that they're portable; but pension plans could be made portable, too.

      The problem with public sector pensions is that they're excluded from the federal laws requiring pensions to be fully funded at all times. Which means states and municipalities can make extravagant offers to unions (to shut them up), but kick the bucket down the road in terms of funding the pension. It's given pensions a bad name in the minds of the public. Unions deserve some blame for accepting the offers, but at the same time it's hard to blame a union for assuming the entity they're negotiating with is negotiating in good faith.

      We should bring pensions back. To do that we need to fix federal law (specifically ERISA) to incentivize corporations to switch back to defined-benefit plans. To problem is that Republicans are firmly in the pocket of corporate interests. And pensions have such a bad name that a Democrat doesn't stand to gain anything from the electorate by pushing for pensions, not that the Democrats could do anything about it anyhow.

      I've not read the book, but everything in the movie indicates that the normal mode did involve a large amount of delta v for Hermes to enter and leave Mars (and Earth) orbit.

      Hermes was in stable orbit the entire time they were down on the surface for the mission, which is how they were able to evacuate at the beginning without worrying about the proper time to rendezvous with Hermes.

      The issue was that Hermes was intended to have enough fuel to leave Earth orbit and get to Mars, enter and then later leave Mars orbit, then return to Earth and enter orbit there. As such it was provided with enough fuel to accomplish those maneuvers, along with the usual safety margin, but no more.

      (Spoilers after this point)

      So when it came time for the fly by they'd already used all the fuel needed to get into and out of Mars orbit on the last pass. As well as some of the fuel they would have used to get back into Earth orbit before they decided to change the plan. As well as a little more re-accelerating for the Earth slingshot. Meaning that from a very rough "number of maneuvers" viewpoint they'd already used somewhere over 3/4ths of their fuel, not counting the safety margin.

      So at the point they got back to Mars they didn't have nearly enough fuel to enter orbit, which is why they needed to do the flyby pickup. Likewise the ascent vehicle was never intended to reach high orbit, which is why they needed to lighten the load so much.

      Hermes would have been coasting back to Earth on fumes after that, with barely enough fuel to decelerate on arrival and no margin for error. In fact, although it wasn't mentioned in the film, it's possible they were intending to return without even enough fuel to fully brake on return and there was a plan to send up a booster with extra fuel to meet them as they arrived.

Either way, there's going to be a literal tipping point and the amount of anticipated wind is the guide. Obviously they over-played the amount of atmosphere and thus the amount of wind on Mars, and clearly did so for dramatic affect. Accurate: no. Dramatically well played: yes.

      The question of Whatney's survival was substitute narration, as already explained. As for freezing, his suit would have had to have not just an insulating effect but a heater just to be out during the -63C day.

      Ruptured lungs is pretty much imploding. His capillaries would also rupture, starting with the ones in the skin and outer muscles and he would slowly bleed out internally, except for his lungs where he would bleed out in about a minute.

That would have added considerably to the soundstage costs, which I'm sure were already considerable. Given that the movie was about Mars and not Gravity, I happily give them a pass on this one. They did well with the zero gee simulation on the Hermes, I think.

      Sound is also a quibble. Almost everything was presented as being heard through the suit mics. The docking and EVA were bad, in that no one was tied down, and the guy crawling over the ship, while not unrealistically done, would have been better portrayed by using a SAFER pack.

      I thought that the huge glass windows in the Hermes were the most unrealistic, unscientific aspect of the movie. Structurally not as sound, and a hazard for both radiation and micrometeoroids.

      Regarding the punctured suit, during the incident in question on the shuttle EVA the astronaut was injured and his blood sealed the hole ( http://www.geoffreylandis.com/... ). The bigger question, I think, is how large a hole would be required to produce any usable thrust without being so large that there's no explosiveness to the decompression?

    What, as opposed to the bullshit claim that by cutting the taxes of corporations and the wealthy somehow that improves everybody's lives?

    Actually cutting taxes and closing loopholes could work quite nicely, the later offsetting the former, generating the same revenue for the government.

    What does not work so well is what we are currently doing. Having high tax rates and lots and lots of loopholes. The former allowing some politicians to make "we're getting money from the rich" claims while the later simultaneously lets corporations and people not actually make those payments implied by the former.

    The current system is an incredible engine of corruption. Letting politicians created special taxes, tax exceptions and various loopholes is license to punish opponents and reward friends. That's one of the benefits of some flat'ish tax system (not literally flat, phases in to give those of lower incomes a break) with no deductions. It prevents politicians from engaging in social engineering and political corruption via the tax system. A lower rate does not have to generate less revenue. Take current revenue, calculate the effective tax rate after credits and deductions, make that the "flat" rate with no deductions (again, slightly more complicated than that since it phases in to give lower incomes a break but its still an easy computation for macro economists). Lower rate, same revenue.

    Ah, yes. 401(K)s. I sure want to put my retirement in the hands of the same people who created a bubble market in the US ...

    You do realize that investing in a 401k does not require you to invest in stocks and bonds? An interest bearing cash option is available, much like a savings account. Even with the historically low average interest rate your return will most likely outperform social security, especially with employer matches.

    Of course if you are decades away from retirement bubbles aren't a problem. When stock prices crash when the bubble breaks your 401k deductions are buying stocks at a cheaper price. That 2007 crash, any stocks you owned already were recovered in about five years judging by the DOW and S&P500 indexes, anything purchased in that timeframe was at a discount and showed a huge gain. Using a NASDAQ index your recovery would have been a little faster. And FYI, you don't have to pick stocks of companies - guess at winners and losers, you can invest in funds that track the previously mentioned indexes. The "averaging in" that occurs via your paycheck's 401k deductions moderate and average out a lot of market volatility.

    So no, you are not highly vulnerable to the idiots on wall street unless you try to play their game, pick winners and losers rather than go with an index fund, or are less than ten years from retirement and needing the money.

    I kinda preferred the book's ending but my main (and still tiny) quibble is that when they are walking on the ring they were definitely walking down a slope, instead of around a ring that was spinning to provide gravity. Along side this they were able to redirect themselves unnaturally in zero g. They could just make a course change without touching anything. So pretty much the special effects people on set simply had no idea about how things work in a zero G environment. These slipups weren't momentary but repeated many times. It kind of ruined the whole suspension of disbelief for a moment. I noticed that when on mars, that there was a scene here and there where they would make a nod to the lower gravity of mars but then go right back to 1G. But most annoyingly there were moments where I could effectively imagine the wires and others where I could picture the ring movie set and which actors were in earth's gravity and which actors were pretending not to be.

    Was it 7 or did I misremember the number of months? In any case many months of activity and drama were skipped. If someone reads the book after seeing the movie there will be plenty of new interesting stuff.

    Still, a very reasonable compromise given time constraints and overall a very good adaptation of a book IMO. Only one somewhat regrettable hollywood'ism near the end of the rescue. Quite forgivable given the quality of the reset of the movie.

    The opening is at least 6ft, so at least 4000 square inches. The air pressure on mars is under 0.1 psi.

    I'm not sure what's the lowest air pressure you could reasonably have inside the habitat. A person doesn't really need the full 14.5+ we have most places on earth. The top slope in a ski resort in Colorado is around 8-9 psi, and maybe 4.5 psi at the top of mount everest. So even if we're pretty generous and suppose the pressure inside the habitat could be taken down to 4 psi and still let a person live, that's still 16000 pounds of pressure on the tarp. Sorry, but no way.

    Anybody know if my estimates are right about how low a pressure a human could reasonably survive in?

    After all the hype about scientific accuracy I was excited to be wowed by it. I wasn't. Not only that I was irritated by a number of things. If all the hype hadn't got me in the mindset that I was about to watch one of the best done science plausible movies ever I could have given a pass on all this in exchange for being entertained. However, due to the hype I went in expecting that the entertainment value would be delivered in the form of scientific accuracy to delight my pedantic inner geek. I am disappoint.

    Motion in Hermes #1: Everyone looked like they were flying on wires. Which they were, but after the astounding work done on Apollo 13 with weightless motion, the bar was pretty high and I expected better from 'one of the most scientifically accurate movies ever'. If not for that hype I wouldn't have been irritated by it because wires are the way it's done.

    Motion in Hermes #2: When they were flying through the hub and got to the ring spokes, do I recall incorrectly or were the spoke access ports stationary relative to the hub? Shouldn't they have been rotating around the hub? (I admit I could be remembering wrong here.)

    Motion in Hermes #3: Why were there curved trajectories every time someone went down into a spoke access port? You don't get sucked in like a vacuum cleaner hose. Granted there would be a slight breeze caused by air circulation and gravity does increase as you move from the hub centerline, but neither of those things could account for the radical accelerations seen in those scenes.

    Growing potatoes: Wouldn't they have been irradiated prior to stowage due to the long storage time and therefore no longer be viable?

    Gut bacteria = composting bacteria?: I don't know about this one but it seemed not right to me. I find it difficult to believe that the gut bacteria in his crap would have been suitable for composting said crap for use as fertilizer and be safe for application to food. Seems a stretch, but maybe someone could correct me if I'm wrong.
