I don't think Watney was teaching on his first day home-- I think the "Day 1" caption just meant it was his first day of his new job as a professor. A bit of 4th-wall-breaking fun: at the end of the novel only one of the crew is in the airlock to meet Watney as he comes aboard and the narration says that if this was a movie, they'd all have been there. Come the movie, and sure enough-- they're all there.

It should be noted that NASA doesn't go to space without a healthy supply of "gray tape" (what they call their version of duck/duct tape) since Gemini (early/mid 60s). It has literally saved lives and missions.

In regards to the hearing their voices after so long, Matt Damon was actually told all the other actors/actresses had finished their voice overs and it was just him left doing his parts. So when they were suddenly there doing their lines, Matt was genuinely emotional because he thought they weren't there any more. I loved this movie, and actually read the book before the movie came out to prepare and understand the movie a bit more. It was a great read.

I really recommend reading the book. It's even funnier, and there's so much more detail. And since you asked, in the book it explains that the HAB breached because there was a small tear in one of the pieces of HAB canvas that was attached to the chamber Mark used to enter and exit. Over time, the strain placed on the canvas caused by the pressurization every time Mark had to enter and exit the HAB caused the tear to stretch and eventually rip apart.

After this, Apollo 13 is a must. This film was about a fictional space disaster. Apollo 13 is the real historical deal.

They don't do the goofy Ironman stuff in the book. Mark suggests it but is voted down immediately. Instead he stays put and Beck comes and gets him as planned. They changed it in the movie to make it more "exciting", like it wasn't already dramatic enough. Speaking of Beck, he and Johanssen become involved on the mission. You find this out in a deleted scene from the movie and it's also in the book. And if you look closely when Beck is waiting to receive the probe Johanssen is watching him and he blows her a kiss. Getting involved on a mission is against regulations, but Lewis is OK with it since by that time it wasn't a normal mission.

I've seen people point out why the hab breached, but in all these reaction videos, I've never seen anybody talk about why the first resupply rocket failed. In the book, it says that one of the food items in the payload, which are basically protein cubes, weren't tested for how they react to shock. So what happened, is that as the rocket launched, the cubes liquefied and suddenly took less space in their containers, and when the rocket staged, it caused a shock that made the now-liquid cubes slosh around, unbalancing the payload. And that shift in weight then broke one of the five retaining bolts keeping the payload secure, transferring the load to another bolt. Except that second bolt had a microfracture that reduced its load capacity to the point of uselessness. So with two bolts broken, the other three didn't have enough strength to handle the weight, and they soon broke as well, leaving the payload loose inside the fairing. Gravity then took over, and the payload slammed into the inside of the fairing, causing a force imbalance that the rocket couldn't correct for. So when you asked if the inspections would've caught the cause of failure, the answer is yes, they would have. The protein cubes would've been deemed unsuitable for launch, and the cracked bolt would've been replaced. And while that exact scenario hasn't happened irl, it shows how minor stuff getting overlooked can lead to catastrophe, similar to Challenger in 1986.

I love that she said it was her second favorite movie, of the ones you've watched together! I rewatch this film all the time. When I saw it in theaters, I was the only one that laughed out loud during the Project Elrond meeting😂 I still feel like the whole scene was written just for me, and no one can take that away from me, lbs!

One of my favorite “if it’s on tv when I’m scrolling through, I have to stop and watch it to the end” movies.

Duct tape was invented by NASA to repair ducts in space

11:57 Hexadecimals means using base-16 math instead of base-10. You use numerals 0-9 plus letters A-F to count: 0 1 2 3 4 5 6 7 8 9 a b c d e f, then 10. It saves characters because (for example) “255” in hexadecimal is only “ff”. Plus, you can translate computer binary (base-2) code into hexadecimal code very easily. Thus, the next bit where they use ASCII code, which is how computers represent letters and numbers.

This is literally shown three times a week in the UK. I know it by heart 😄

The book makes it clearer, the airlock was a weak point, from the constant pressure changes. Mark gets in to the bad habit of using one more than the other for convenience, kicking himself when he realizes after he put extra strain on it.

What I found really fun about this movie was the soundtrack.

29:33 🤣I like to think somewhere out there in the world is Matt Damon planting random potatoes

Fun fact, 5/6 of the actors that play the crew are actually in marvel movies, not mcu, necessarily, but still marvel movies. Also, not very big parts, necessarily, either. Jessica chastain- X-men dark Phoenix Matt Damon- Thor: ragnarok Sebastian Stan- several mcu movies (winter soldier) Kate Mara- fantastic four Michael pena- ant man 1&2.

As far as the water goes, if you look at old footage of the space shuttle Challenger exploding, that is basically the same chemical reaction that produced the water in the movie. 2H2 + O2 = 2H20

'Looks pretty hot.' the noon temperature, in summer, at the equator: 20C. Coldest: around -150C

But ironically, they were talking about the Elrond Secret Meeting, with Boromir in the room!

I highly recommend checking out the book it was based on, it goes into a lot more details (in a very clear and engaging way, no complicated science knowledge required) that explain a couple of the things you guys were wondering about. (I would also recommend the writer's other books, _Artemis_ and _Project Hail Mary_ - both are also sci-fi, _Artemis_ is kind of a heist story while _Project Hail Mary_ is closer to _The Martian._ Both also have movie adaptations planned, I believe.)

You asked about spacesuit weight. Weight is relative. The smaller the object you're on/near and/or the less the amount of centrical force you're experiencing, the less relative weight you will experience. Weight on Mars is 38% of weight on Earth; so if you weighed 100 lbs on Earth, you would weigh only 38 lbs on Mars. What Watney stamps against his abdomen before digging out the imbedded wire is injections of a topical anesthetic, to kill pain. "I'm not gonna die here" is a mission statement. Everything else follows from that. Yeah, space travel takes a while. More so because Earth and Mars have different orbits. Recall the Sun is 93 million miles away from Earth; sometimes Mars is on the OTHER side of the Sun. Our orbit is 365 days; Mars is slightly-less than two years (687 Earth days). Distance from Earth to Mars varies from 35 million miles to 249 million miles. The closest we got to Mars in 2022 was about 50 million miles, in November, before moving apart again. Also, most people think all of our solar system orbits are circular; they are not. They are elliptical, not circular. Earth's orbit is elliptical, and Mars is even MORE elliptical. Meaning more difficulty setting up travel routes. To get to Mars, we have to coordinate how long it takes us to travel a set distance against where Mars will be in relation to us. And depending on WHEN we set out, that distance and location will be different every time, so travel time will fluctuate wildly. Usually, we choose a time Mars will be closest and calculate back from that to determine where Mars will be at that time and when we have to be ready to leave to get there. In this instance, the crucial limit is how soon they can get to Mars before Watney starves to death or some other catastrophe occurs. It's further complicated by lack of supplies; there's a reason they can't just turn around and go back; they could run out of food, oxygen, or fuel if they don't pick up more before the attempt. Mars is an environment not very less hostile to life (especially human life) than straight up outer space. Mars is farther from the Sun, so it's colder (average temp globally is -60°C/-76°F), has a much thinner atmosphere which is mostly carbon dioxide. You can survive on Mars without a space suit for about 2 minutes. Inspections would not have helped. The problem was weight shift in supply items (payload) that were liquid. Inspections are for the function of the rocket. Payload details were overlooked, so would not have been on the checklist. The 'shimmy' would not have been foreseen.

Definitely one of my top favorite movies, very well done in every way

Agreeing with everybody's who's recommending the book (the audio book is also awesome) - it is very funny and you get more details, to explain some of the things they show in the film. Although not always - in the book, the bit about him doing self-surgery is about a paragraph long. OTOH, the blown-out-airlock, I think, was much more dramatic in the movie. Mark Watney is hilarious and you'd love all his thoughts about things. Anyway, enjoyed the reaction :)

Mars gravity is one third of Earth's.

Okay, I got two space themed movies for you. Gravity and Space Cowboys.

"Home Alone: Space Version" Lmfao, I just imagined Mark setting traps for burglar martians.

I'm pretty sure what Mark used on himself before dealing with his cut was a topical anesthesia

Surprisingly fun and feel-good movie from Ridley Scott.

According to several scientists, there's really only one major scientific error in this movie, and that is, given the low, low atmospheric pressure on Mars even a hurricane sized storm would have winds stronger than a light summer breeze. The astronauts were in no real danger at the beginning, but they went with the " rough storm" because otherwise they wouldn't have a story.

Nice reaction ☺️ I've never laughed more with a book than I did with this one. Totally recommend 👍

Your question about the weight of his suit.. It looks quite a bit lighter than the suits worn by the Apollo astronauts, which were over 200 pounds. But, the gravity on Mars is only 38% as great as on Earth, so you can carry almost three times as much mass.

One of the most accurate sci-fi movies made!!!

This is a great movie. Love the reaction, keep it up!!!

In reality that storm would not be powerful enough to scrub the mission. You have to keep in mind that Mars has a third of the gravity that earth has so a storm with the winds like that wouldn't have enough power to tip over the mav.

I am SO sorry I have forgotten the other reactor's name, but did I catch that she has not seen the LOTR movies? really??? Oh please, I would love to see her reaction to the Director's Cut long versions. They are movies full of heart and character, as well as adventure, beautiful scenery and beautiful music. I think she would like them very much. Everyone is so surprised about how short the movies feel, despite their length, because they are that absorbing and immersive. And as an Epic story, she may find some similarities between LOTR and the many amazing Epic Chinese movies set in past history of the Empire.

Obviously they had to change and leave a Lot out that was in the book. Tip #1 is get the Audiobook that I listened to on my daily commutes, the voice acting is just Incredible. "Duct Tape works anywhere and should be Worshipped!" Also they did Not do the Ironman stunt at the end. Otherwise still a good flick but the book is just Incredible.

Should have listened to the disco song during the end credits!

Love it, great fun!

Thanks for the video. I enjoyed it.

13:57 "Mmmm... dick move". LOL I could not have said it better.

Astronauts train on things until they can do them as a reflex. They train and train and train until they do not have to even think about a task, they just do it. They cross train in other fields in case something happens. They all learn how to repair things on their vessel. They all go through survival training. And for a Mars base mission... that would be way more intense than normal astronaut training. He already knows a lot of chemistry and biology from being a botanist. Honestly, I don't feel this movie or book is all that far fetched. Mars is gonna be hard... but I think we'll be able to make it work there. I mean, look at the exploration we did 600 years ago with nothing but the stars for navigation and wooden sailing ships.

I hope someday there is a movie of the book "David Starr: Space Ranger", perhaps he could meet Mark Watney: Space Pirate. 😉

the film that finally proved that Matt Damon is a high-class actor, and not just another clown running with a gun in his hand in front of the camera.

Great Reaction Guys

i have watched couple of reactions to this movie and im stunned people have no clue what hexadecimal is lol

4:40 where you're thankful they left him all the stuff, and commented that it might have been because they left in a hurry. No. Really no. Anything that doesn't absolutely need to get to orbit stays on the ground. To give you an idea, to lift a kilo of mass, you need a kilo of fuel. But the fuel has to also lift its own weight, so you need even more fuel to lift it. To send NASA's space shuttle into orbit around Earth took 3.5 million pounds of fuel (I hate the imperial system). That's the weight of 15 blue whales, by comparison. That lifted the shuttle, the crew, and whatever equipment they needed, and they measured everything to the ounce. So the idea that they would pack up and load everything into the shuttle to take back with them is just not feasible. They wouldn't even take the entire shuttle with them. They'd leave the landing equipment behind because every ounce of weight they take to orbit means multiple times that of fuel they'd need to get it there. Less than on Earth, because Mars gravity is lower, but still something that the engineers who built it would have to take careful consideration of.

He had a much easier time in the movie than in the book.

All astronauts these days are taught to staple their own wounds closed. Just in case.

If Watney has been a real nerd, he would have used his potatoes to power his computer.

Chemist making a bomb: A lot of the training for chemistry involves learning what not to do. Way too many ways to make a bomb or poison gas, or any number of things that disagree with humans.

An advert for Duct tape.... You guys need to play "Stationeers" ... be your own Mark Watney

Actually i dont think this Was duct tape. It was some Kind of titanium tape they use for airplanes too, which costs about 1000 Dollar per roll

How is "Hot Stuff" the least disco song she owns, when we clearly hear him listening to "Starman" and "Waterloo" later?? 😂

If there was ever a time when strongest cuss-words possible were justified, the 'sewing-up' and 'haven't told the crew' moments were well-written for precisely the harshest language. Yet... it still doesn't help!! (That's sooo frustrating - we need to find cuss-words that really WORK - stop the pain, stop the agony!! ha ha)

Question: Which is a better stranded survival movie? Cast Away or the Martian?

Why’d you stop making vids with Domi? Loved you two together

Yay, Jessie is back! 🤩🤗 This is a great movie to react to. Thank you for sharing!

Sooooo…. How many of that cast are in the Fox/Marvel universe???

China number four!

Nominated for 7 Oscars including Best Picture but didn't win any.

This is my favorite movie that's not lord of the rings

If you haven't watched it maybe Gladiator which was also directed by Ridley Scott? I love The Martian close to my favourite movie and/or book.

Wife or husband.

You do not exhale oxygen. I'm just sayin'.

I loved the reaction but that chicks voice was so annoying ngl

"everything possible with Chinese"........HA! You're funny. I love fan fiction too.
