I’m stranded on Mars.
I have no way to communicate with Earth.
If the Oxygenator breaks down, I’ll suffocate.
If the Water Reclaimer breaks down, I’ll die of thirst.
If the Habitat breaches, I’ll just kind of explode.
If none of those things happen, I’ll eventually run out of food and starve to death.
I’m screwed
The above quote is from the rear cover of the book and it sets the premise of the story so well that I knew I was going to enjoy it. Yes I know the film starring Matt Damon came out in 2015, but I’ve never seen it. This is also my first time reading an Andy Weir book and with the release of smash hit film Project Hail Mary earlier this year he is difficult to avoid at the moment, so I thought I would go back to the beginning and his first novel. There are one or two scientific errors (see spoiler alert at the end of this blog) but it appears to be largely accurate, I’m not a space expert by any means so I could largely ignore the plot devices I knew wouldn’t work as the plot is so well told, and what I did know would work is properly explained. It is also very funny, which I wasn’t expecting.We start with Mark Watney realising he is alone on Mars as the rest of the crew of Earth’s third manned mission to Mars have taken off without him during an emergency evacuation of the planet as they believed he was dead in a sandstorm that had potential to destroy both their habitat and also the craft ready to take them back to orbit. They did attempt to find his body but couldn’t see anything due to the sand and had to give up as the lander was starting to lean to an degree that would have prevented take off. Watney however was injured by a flying radio antenna which pierced his spacesuit and took out his communication to the Mars Ascent Vehicle which was why they saw no vital signs from him.
The style of the novel is interesting as we don’t follow Watney in real time as he does things but in retrospect as he writes up his log, so when things go wrong the first clue is often a gap in the date at the start of the next log entry. My first impression whilst reading was that was going to be the entire structure because after all who else can he talk to, the habitat radio equipment was destroyed in the storm. But on page forty nine I finally got a chapter which wasn’t Watney’s monologue, entertaining as that was. and it was somebody on Earth realising that Watney was alive. Mindy Park had looked at satellite images of the Ares 3 landing site and spotted that the pop up tents were deployed and the rovers weren’t where they should be, that then lifted the story to two parallel tales, the day to day survival of Mark Watney and the NASA conversations as to what they could do to help, which frankly initially at least, looked like very little.
The story develops at Watney solves one problem after another, often whilst inadvertently causing another. He was originally picked as the mission botanist, but as that would have involved little work other than experiments in growing a small number of plants to see how they would cope he was also trained as the maintenance engineer, both skills that would be vital for his survival. He quickly realised that if he could wait it out until the next mission was due then he had insufficient calories to keep him going, so planting food would be essential. But Martian soil didn’t have the nutrients or bacteria needed to successfully grow anything so he needed to solve that, he also didn’t have enough water for crops as well as himself so that needed to be fixed somehow. Weir had obviously done a considerable amount of research around the various issues and how to get round them with the resources Watney would reasonably have to hand helped of course by the fact it was supposed to be a six person mission on the surface for a month and five of them had left after just six days leaving a lot of food and water to keep Watney going for months whilst he figured out how to create more starting with the handful of potatoes he had.
It’s really well written and an entertaining read and now I’m tempted to watch the film and definitely read more by Andy Weir.

- The massive dust storm that forces the crew to abandon Mars leaving Watney behind could happen but wouldn’t have the life threatening implications given in the story, the Martian atmosphere is too rarefied to cause that sort of damage to equipment, especially something as heavy as the launch craft or the Habitat and wouldn’t blow an antenna across to Watney with so much force as to penetrate his spacesuit and almost kill him. But I know why it is written that way as Weir needed a plot device to plausibly abandon Watney. The sandstorm later on in the book, which causes him to make a massive diversion, is a far more accurate depiction in that several days after entering it he still hasn’t realised anything is wrong.
- What would kill Watney however, and well before a rescue could get there, would be cosmic radiation, there is simply no way he would survive that long especially with the number of EVA’s he performs.
With those caveats, and I believe there are more issues with the film which aren’t in the book but which presumably were changed to make it more dramatic, in the book the science is pretty good especially the chemistry and the botanical solution for growing potatoes.
