Weir wrote the book to be as scientifically accurate as possible and his writing included extensive research into orbital mechanics, conditions on Mars, the history of manned spaceflight, and botany. He even wrote his own program in order to predict the best launch dates and the orbit distances between Earth and Mars.

He was a computer programmer but given his recent success has quit his day job in order to focus more on writing as that had always been his dream. Andy Weir actually personally created software to calculate the ship's arrival times (on Earth and on Mars) down to the exact minute in his novel.

Originally published as a free serial on his website, some readers requested he make it available on Kindle. First sold for 99 cents, the novel made it to the Kindle bestsellers list. Weir was then approached by a literary agent and sold the rights of the book to Crown Publishing Group. The print version (slightly edited from the original) of the novel debuted at #12 on The New York Times bestseller list. The Wall Street Journal called the novel "the best pure sci-fi novel in years".

A fan-fiction story written by Weir, "Lacero" was published in the 2016 edition of "Ready Player One", making it canonical to the book's fictional universe. The work functions as a prequel to the main novel.

In 2016, Weir released "The Principles of Uncertainty" a collection of short stories on the TAPAS app platform for short fiction.

Weir is working on his second novel, initially titled "Zhek". He describes it as "A more traditional sci-fi novel. It has aliens, telepathy, faster-than-light travel, etc."

Andy Weir 8

An astronaut, Matt Damon, Ridley Scott, Andy Weir and someone else.

Weir was born and raised in California. He is an only child. His father is an accelerator physicist and his mother an electrical-engineer who divorced when he was 8. Weir grew up reading classic science fiction such as the works of Arthur C. Clarke and Isaac Asimov.

At the age of 15, he began working as a computer programmer for Sandia National Laboratories. He studied computer science at UC San Diego, although he did not graduate. He worked as a programmer for several software companies, including AOL, Palm, MobileIron and Blizzard, where he worked on the video game Warcraft II: Tides of Darkness.

Weir began writing science fiction in his 20's and published work on his website for years. He also authored a humour web comic called "Casey and Andy" featuring fictionalised "mad scientist" versions of himself, Casey and his friends (such as writer Jennifer Brozek) from 2002 to 2008; he also briefly worked on another comic called "Chesire Crossing" bridging Alice in WonderlandPeter Pan and The Wizard of Oz. The attention these gained him has been attributed as later helping launch his writing career, following the failure to publish his first novel attempt called "Theft of Pride". His first work to gain significant attention was "The Egg", a short story that has been adapted into a number of YouTube videos and a one-act play.

He currently lives in Mountain View, California, in a rented two-bedroom maisonette. Since he has a deep fear of flying, he never visited the set of the film adaptation of The Martian in Budapest, where most of the scenes set on Mars were shot at Korda Studios. however, in 2015, with the help of therapy and medication, he was able to fly to Houston to visit the Johnson Space Center, and to San Diego to attend San Diego Comic-Con.

Weir has stated that he is agnostic. He considers himself to be a fiscally conservative social liberal, and tries to keep his political views out of his writing.
