idk why but i absolutely love the tiny touch of having him also recover Sojourner
In the book it was meant for an alternative means of communication. Sojourner has six wheels that turn independently. The thought had been to write the alphabet on the wheels, and NASA can then spell out messages. However, Mark was never able to get Sojourner to work in the book. In the end he had to use ASCII to get messages and get the rover hack.
the basic idea was that he probably thought the rover had parts he could use so might as well taking it back to base.
@@santoshchouhan2822 Where'd that come from? Sojurner's top speed was tens of meters per hour and last we heard from it, it was still close to Pathfinder. They lasted longer than designed, yeah, but they were a very weak pair.
@@nevadaxelizabeth In that kind of scenario, there's no such thing as too much equipment.
@@santoshchouhan2822 Where in the hell are you getting 6 kilometers from? Sojourner drove a *grand total* of 100 meters, or about 300 feet, during the 80 some-odd days it was active. The last command Sojourner was given was to stay still for some set amount of time and to then drive around Pathfinder. So uh, where'd the other 5.9 kilometers come from?
Imagine looking 200 million miles away for some type of human contact. Gives me goosebumps thinking about
he looks up in the sky to earth
introverts' heaven!
Its only 138.69 million mi, so you are off by 70 million miles.
50 million not 200 million
You're all wrong... and you're all right as well.
The AVERAGE distance between Earth and Mars is 140 million miles (225 million km)... BUT depending on where Earth and Mars are in their orbits relative to each other, they can be anywhere from 34 million miles (55 million km) to 250 million miles (401 million km) apart. This vast difference is one of the reasons why there launch windows to give workable travel times for the minimum fuel usage are limited. There is only one launch window every 26 months.
Watney in the Book: Has to meticulously break off Pathfinder's Solar Panels as well as construct a ramp from Martian materials to carry the lander and panels onto the Rover's roof.
Watney in movie: Just uses a Crane.
One of those things, that someday the real Martian mission planners will consider.
'Why don't we bring a crane?'
And 'What is wrong with disco in the music library?'
Cue "The Hustle (1975)" by Van McCoy ...
Honestly I thought that was a great addition. The Book has "room" for all the little challenges he faces, but in a movie, less can be more. Though I did kind of wish they had included the dust storm plot.
@@SmallLab129 The martian would make such a great 10 or 12 episode series. Put everything in it.
And it makes sense. Why _wouldn't_ it have a crane if it's supposed to assist in a long-term mission where they need to construct a base?
@@NurmYokai Don't forget the "emergency potato"
"Are you receiving me?"
Camers points to "No"
Watney: DANG!!! ....... "Uh oh".
I like that Watney put "No" out there, but it would not be used for that initial contact. The camera either points to "Yes" or it never moves.
😅
But he knew that any future Q&A (provided he got the initial "yes" would require the Earth crew to have a "no" option, so he put it in there from the start.
@@bobmclennan1727 Don't spoil our fun with the facts 😁
@@hankjones3527 i'm sorry that you're the type of person who thinks that fun and facts can't coexist.
@@TheEvilCheesecake I'm glad you are sorry. You should be.
It’s interesting because pathfinder deployed Sojourner just like perseverance deployed ingenuity, since a rover was risky back then. Now we have rovers just driving around on Mars regularly. I wonder if ingenuity will start that next leap.
I keep having to remind myself how big the rovers actually are.
True, maybe next time we'll have a rover in a helicopter in a rover.
What’s ingenuity? Can you elaborate for me please?
@@GetERekted ingenuity is a small aerial drone that the latest mars rover brought with it
I read the book before seeing the movie and I have to say that both were some of the best science fiction I’ve encountered in the past 25 years. Instead of the cyberpunk, dystopian, post apocalyptic trope of the 90s and 2000s where the ending really depressed the reader, we have a “Okay let’s say a prayer, be strong,science the shit out of this, not give up, get to work solving the problems”. We need more SF that speaks of a hopeful future rather than SF that that tells the readers that there no hope whatsoever. The hopeless SF does more harm than good.
hopeless science fiction also tells us we have to be wary of creating rampant AI that wants to kill us.
what does more harm than good is our death-drive capitalist system. art is going to reflect peoples feelings so, get ready for even MORE dystopian, sci fi.
it probably helps that the book was written by a NASA engineer
Robert Sawyer writes about positive futures
you must be easily entertained
I think particularly this part of the martian's story from finding pathfinder+sojourner to establishing text2text via the rover is so insanely well condensed in the movie compared to the book's minute attention to detail. In the book Mark has to consider how to build a rock ramp to even load pathfinder onto his trailer's roof, consider the insanely low voltage these ran on and throttle his hab electricity power through a self made breaker kit (I believe it was like 1.2v from a non-rechargeable lithium ion battery) which trips when he loses connection by short circuiting pathfinder with the drill used to turn his rover into a convertible with a balloon on top. I don't know if it's a testament to the film's efficiency in conveying this story bead in the condensed way it does or if it should be seen as unnecessary plot filler in the book, I still very much liked the book's version of Mark a tiny bit more.
The movie did a great job of condensing the story to fit the time constraints
Not to mention, it kept the movie’s storyline from becoming too technical. I’m still a little in the dark about hexadecimals. But I’m old enough to remember a time where computers were the stuff of science fiction and Star Trek. I never dreamed as a kid that I would have a desktop, let alone a phone/tablet connected something called the internet which put, at my fingertips, the sum of human knowledge.
I’m still waiting on my flying car, jet pack, space stations the size of cities and bases on the moon and Mars, though. I’m fifty nine as of this writing.
Get your asses moving, kids.
You can thank me later
@@airdriver hey I watched the jetsons, I was expecting my flying car that folds into a suitcase by now.
Hex is just base 16 numbers.
@@airdriver Yessir! You might be interested to know that NASA is currently flying missions to make a permanent moon base! It's called the Artemis Program, and their second mission is set to launch next year.
As for hexadeximals (hex), they're a system of numbers that repeat every 16 characters, unlike our usual method of counting (which is called decimal, or denary!), that does so every 10.
We call this "base-16" (our own numbers are "base-10")
Decimal, What you'd be used to, goes: 0, 1, 2, 3, 4 ,5 ,6, 7, 8, 9. Then the pattern repeats (10, 11, 12, 13, etc.)
Every time the pattern gets "full", we add a new column (think of this as going from 9 -> 10 or 99 -> 100)
Each new column, represents a power of 10 (1, 10, 100, 1000).
So, in decimal, 345 is shown as: (100 times 3) + (10 times 4) + (1 times 5), Which is equal to the number 345 (no surprises here)
(I apologise if this may seem like I'm being a bit patronising, but this should hopefully let you compare decimal to hex easier)
Hex uses: 0, 1, 2, 3, 4 ,5 ,6, 7, 8, 9, *but also*: A, B, C, D, E, F.
These are in place of 10, 11, 12, 13, 14 and 15 respectively (A = 10, F = 15)
This is often the part that people find confusing:
Like decimal, the pattern then repeats, with 10, 11, 12, etc. However, unlike each new column representing a power of 10, this time it becomes a power of 15! (1, 15, 225, 3375, etc.)
Which means "10" in hex is actually equal to the number 16, with "1F" being equal to 31!
So, in hex, "345" is shown as: (225 times 3) + (15 times 4) + (1 times 5), which is equal to the number 837!
This seems very complicated for us (and it is!), but computers are good at this sort of math, and it lets them express any number from 0 to 15 with only 1 character, which saves a lot of space in the long run. Computers are limited by the length of characters they can put together at a time. (I'm sure you've heard the phrase "8-bit" or "16-bit" or some variation). With systems like Hexadecimal, you can store much bigger numbers in the same amount of physical space! (9999 in decimal is a *lot* smaller than FFFF in hex)
Sorry if this is too long-winded! Hope this helps you with Hexadecimals :D
I mean,
A flatbed rover with a crane is better than the big round moon rovers.
hilarious that the prop department built a mars lander with lights for nobody to see and makes beeps for nobody to hear
On some (many, ??) it's visual diagnostics for ground/Earth testing; seen one and they had money to burn... BUT having wrote that, permanent spacecraft RGB (UGH) would take up precious weight and space and power. And yes that seems rather unnecessary for something that won't ever be seen again by human handlers.
Wonder if NASA or JPL ever commented on that?
@@NurmYokai Remember back in the day video game had cheat codes? Cheat codes were often added to make development easier, just like built-in hardware test functions. It is simply safer to not remove them when everything is working, removing development features has risk of breaking things.
But today we have all these fancy simulation software for testing and debugging, plus it is a lot cheaper to manufacture most hardware now, so these quirks are mostly history now, mostly just old IT person may remember them; just like Bedlam DL3 (but this one is bit more famous).
exactly what i was thinking 😂
@@8749236 JTAG points on the PCB weigh a lot less (actually, they take away milligrams of solder mask and copper for trace spacing) and have no additional active parts over the existing processor. Then you can plug your test equipment straight onto them on earth.
A lot of the machinery just makes sounds.
As an example, the NASA crew operating... Opportunity, I think, made it play itself "Happy Birthday" using its testing equipment since it hums at a consistent tune.
These unused scenes are so weird to me. I've seen the movie a hundred times, it trips me up when the dialog suddenly changes.
Every once in awhile, it's worth getting the extended cut version of a movie.
@@NurmYokai
I got the Extended Version of The Martian. Well worth it.

“This won’t exactly be an Algonquin Round Table with a witty repartee.”

He was unneccessarily snarky in that moment.
Unrealistic character, noone and I mean noone is going to be making snarky comments considering the scope of what they are doing and the hurdles they are overcoming. If he's smart enough to be in that room he's smart enough to understand how absurd he's being

Hermoso homenaje que le hicieron a la pathfinder en esta película. El primer rover en pisar marte en el año 1997
you have a quality clip here, thanks for that :)
Tim guy still dare to argue ...
Imagine if it was him that is stranded in the Mars
He's a typical Indian that always want to get his last words in or thinks he's entitled to something 24/7. (And yes, I'm Indian so I know LOL)
I kinda overlooked this movie when it first came out, 2015 was a pretty strong year for films this past decade a lot to see, but looking back on it and having rewatched it twice now, it’s honestly a top 20 film of the decade and probably Ridley’s best since American Gangster or even Gladiator.
I absolutely love this movie and the book was even better, showing exactly how much a smart ass Mark watney truly was
I would've pointed at NO just to be that guy.
You're not that guy pal, you're not that guy.
After watching Ted Lasso, it's crazy seeing Tim (the sassy Commtech guy) is the same actor who plays Nate in that show.
Great to see Nick Mohammed in more stuff. He was great in this and Ted Lasso.
Is that Nate the Great? He really is a Wonder Kid!
Great movie!

Hope you enjoyed the video.
Kind of reminds me of Futurama where theirs a leftover Apollo lander still just sitting on the moon undisturbed at hounds years into the future.
wow, never watched this movie but as a space nerd, what a cool throwback.
Watch the "extended cut" version. It will be worth the time.
@@NurmYokai ill check it out! thanks!
Watch the movie and read the book. If nothing else it’s just a simple story of survival and perseverance. Both the author and producer played funny with the science but it was a good story. Best science fiction I’ve read in almost 25 years.
You're a space nerd yet you've never watched The Martian?
For the love of Elon, Yoyleb17, go watch The Martian.
Love this movie
daniel Brian is yelling YES YES YES
The thing is the people at NASA want to leave where pathfinder died
Humanity is almost at the point where NASA 'relics' could be salvaged. Like salvaging relics from the Titanic. We hope these space milestones are left alone.
Excluding retrieval of parts from orbit:
The first (sanctioned) salvaging operation took place on the Moon. Apollo 12 (November 1969) astronauts Pete Conrad and Alan Bean retrieved parts from the Surveyor 3.
See also the (science fiction) movie "Salvage" (1979).

This goes to show how important logistics is
This wasn't a logistics issue
I always think about this, like why would he need a no option?
benedict wong from 15 storeys high to every single space movie
What if they pointed the camera at no? I mean by the fact that NASA is answering, in any form, means they are receiving him.
My thought exactly. The no plate was kind of useless
@@ulicqueldromal Mark: "Do you currently have a plan to rescue me?" NASA: "No."
From nasa to Ted Lasso.
This is what it feels like for a guy to finally get responded to on a dating app.
When you look at the details, you realise that when he dropped the placate, it dropped very slow because Mars has only 40% of the Earth's gravity. I love it, that they did their homework and paid attention to the details.
If you look real close In 1:25 you can see the Martian satellite
Yes. It's little right from middle
I'm fairly certain that's meant to be earth. It would be borderline impossible for him to align that with a satellite let alone for him to know where the satellite is.
@@will2brown50 that's not what he meant. He didn't align it. The comment is pointing out that that thing is satellite
Natural satellite ?
That's the Earth...
The best science fiction movie I have ever seen except that there are no storms on the Mars dangerous for people due to the rarefied atmosphere there.
If you’re referring to the dust storms you couldn’t be more wrong. Mars is well known for it’s essentially planet wide dust storms on occasion, and they’ve spelled doom for many rovers. If one of those things hits a human settlement, you better hope you’re inside.
@@RAdaltonracer So how many rovers were doomed by storms on Mars? You should better study physics.
What? Mars is super infamous for massive storms that are continental size. In fact a storm is what killed the Opportunity rover and many others before it.
@@ditto9300 The size of storms does not matter. The density of the atmosphere is too low.
@NurBull It really depends. Most storms are not very dangerous, some of the most powerful storms on Mars would only be half as strong as some of the most powerful storms here on Earth. But also consider you are on Mars, and everything is dangerous including 30mph storms.
I just realized that Nick Mohammed was in this movie. Never noticed him before this.
😂😂😂they can just say NO and our boy would have just laughed at the humour
Why did he need a "no" option?
If they pointed camera to no, he would still know they were recieving!
No so that further questions can be asked. He set it up for future questions. And also, they could answer no if the image quality was terrible or required improvement.
In the novel, there was no "No" option. It was just "Yes" and "keep the camera pointed here if you can't read me" - or something along those lines.
@@duze5822 makes more sense than in the film!
People do dopey stuff all the time like this. Even highly trained astronaut/botanists stuck on Mars.
@@duze5822 Commenting since I just looked it up. The two signs were "Are you receiving?" and "Point here for yes." But you are absolutely correct; there was no 'No'.
Imagine the camera is pointing at "No".. haha that's gonna be huge confusion to Mark. 🤔🤔🤔🤣
... that time in the conversation when everyone's 'favorite technician' decides to take a break ...
Who here thinks the connections on Sojourner match up with those on his equipment? Remember the air filter scene in Apollo 13?
Yep...that was my first thought too.
because adding another half hour to the movie as he tries to integrate different systems with each other doesn't add anything to the story. A movie has to deal with a limited length, you have to focus on what is important to tell the story and move the plot forward.
There is an explanation in the book where he talks about how NASA stated to meticulously make all connections comptable BECAUSE of the Apollo mission. If it hadn't happened, you would be right.
@@bibliophilelady6106 sojourner would not fall under that, unmanned and no reclamation. No need to externally power it or connect to download.
@@bibliophilelady6106 maybe within a mission, but to suggest connections from late Apollo working on the Shuttle serves no purpose. Also, Sojourner was unmanned and non returning, being compatible with tech 50 years later….
... and what could he satirically surmise from the irony of them having pointed to the "NO" choice?
Wadi Rum is beautiful place, leave only footprints 👣
they really turned a piece of scrap metal into a lovable character
What was the battery pack powering originally i wonder. was it an essential system? a back up system? or was it just a redundant spare?
The best line of the film - “I'll have to science the shit out of it”.
Nate the great
the wonderkid
I can imagine a movie taking place on Venus just like the Martian, and the main character having to retrieve Venera 7..
He would be died.
Those landers would be probably in a very bad shape by that point, Keep in mind they are in 427°C for more than 30 years
If humans went to Venus, we’d die in under half an hour. Unless we developed some kind of heat resistant suit
I cant because everything will have been melted including the main character lol
Theybgot practically incinerated
It’s Nate!
Yeah asking yes or no questions/only being able to point the camera isn’t ideal, but for an initial confirmation of working communication systems, it’s necessary for both parties. A more versatile and robust system will be put in place later (as is shown in the film with hexadecimal), but for now, first contact is needed in order to establish a proper system, Mr. Finest-Comm-Tech
Imagine pointing at NO😂
Mark would have been devastated

" Are you receiving me ?
Mission Control: " Who is this, you have no authorization to be using NASA Equipment " " Leave the planet " " Final Warning "
Callback to the radio conversation in The Final Countdown (1980)?

"You're on a what?!"
"I repeat. I am Senator Samuel S. Chapman onboard the U.S.S. Nimitz."
"Alright, whoever the hell you are. Use of military frequencies by unauthorized personnel is a felony."
"Now listen here, sir!" Senator Chapman, U.S.S. Nimitz (1968-2026)
"As we have no aircraft carrier Nimitz and no Captain Yelland I suggest, a*, that you stop impersonating some other a* and get off the air! You're wasting our time!" Pearl Harbor (1941)
I've always wondered, if they didn't receive his signal, was he really expecting a "NO" response?
Ive always found it funny that he included a NO option as well lol
Thats a common joke in my family about this scene. What would he have done if the camera had pointed to "No". Probably laughed, because in a way, both answers are "yes"
There was no „No“ sign in the book. Mark thought about the same thing and trolled NASA.
El chiste es que si dicen si o no , es una victoria!!
Tim may have been a smart mouth at JPL, but he did pretty well as a Kit Man and then assistant coach at AFC Richmond (and for a short while at West Ham). Had to change his name for some reason, though.
When I get a match on Tinder
I love this movie. I've watched it at least half a dozen times.
The thing I think is the most unrealistic though - is the relatively luxurious quarters and transportation equipment. Can you imagine building a space ship like that? Look at the amount of space they have in the "Gym".
Look at all that plastic Sheeting he uses ... would they really sent that much plastic sheeting to Mars?
And those tubes he puts everyone's personal property into? Why are those there?
.
You should read the book. It explains how most of the equipment was sent in several supply missions and they built the HAB their first day. The material the hab itself is made of is a canvas that was folded up. They had to unfold and pitch the structure like a tent.
Tubes, you'd need a lot of storage for these missions.
Space for gym and stuff, it's the 2030s and you're sending people on journeys that will last for 1-1.5 years (only going, not even counting the return home). Sending them in crammed up spaces isn't good for psychology and also the mission itself. Hermes was providing artificial gravity for it's habitants by making the vehicle turn around itself, so you need a wider vehicle already. Plus, if you have the opportunity and tech, why not take it? Humanity won't travel in space in narrow tubes for forever.
Plastic sheeting can help with protecting things from martian dust, and also plastic is cheap, easy to use, and usable in space.
I hope the dude at least got a reprimand if not fired
He was on the orginal crew for the Pathfinder program. You wouldn't fire someone who is as smart as he is just because he can be kind of a smartass dickhead.

man it would've been the biggest troll move if they pointed the camera at no
Blud got dem AOC monitor
Martian 👍👍👍👏👏👏👌👌👌👌🎬🎬🎬📽📽📽
Something that I think is weird is that he was able to hear the camera go up even tho he had his helmet up
The Martian atmosphere is thin, but you can hear sound. But if you're human, don't do it outside without a SUIT. You'll enjoy sounds longer.
Check out "NASA's Perseverance Rover Hears Ingenuity Mars Helicopter in Flight."
"On April 30, 2021, NASA's Perseverance rover made history as the first spacecraft to record sounds from another spacecraft on another planet."
@@NurmYokai He's also sitting right next to it, maybe on one of the solar panels itself, so a reason for him knowing about the camera activating is he could have felt the vibrations of the camera starting to move.
@balls up ok first of all, he has a helmet on, which means if not it being completely muffled, it's at least quieter, but even than the camera wouldn't be that loud. Connected to the fact that the helmet seems to probably be pretty thick, and looks to have foam in it, which muffles sound more. So pretty much everything points to the fact that he wouldn't be able to hear it. I know I just said a whole paragraph to prove a point but really I don't care about it I just wanted to say it
@@lc8339 he probably has a micro that transmits ambient sound to him
Seriously when humanity finially reaches mars i hope the first thing they do is recover all the rovers that were sent there
Yeah. And we wanna live here, on Mars. Right.
1:24
That's no star. That's a satellite.
when i first watch the scene i thought he pointed at no.
Wong!
Imagine they saw his message and answered "NO" 😂
you know Kim was not acting like an idiot, all that speaking was for the audience to understand what was happening, after all in the next scene he was able to tell what Mark was doing with ASCII in just one look.
He was being pessimistic and snarky while someones life is on the line. Of course he is an asshole.
I realise something : the film take place in 2035 and the computers are 90’s Model and today you can’t even use a Computer with 4 year old version off Windows . Had the guy at JPL digg out a museum piece too run the prob?
Looks nothing like actual Sojourner landing site. The movie "Red Planet" actual got that one right.
''Are you receiving me, yes or no?''. That's 1 answer question. If they answer yes, they obviously are and if they answer no, they obviously lying since they were able to respond.
Imagine if they pointed the camera at 'no'
3:39 "I am the smartest man in the world! ...Oh wait."
Question.. why would he make a sign for no? If they weren't receiving how would the see the sign and know to point it at no?
He pointed to no 😅
Why did they redesign Pathfinder in the Martian?
How much quicker would communication be if this movie was made after the perseverance rover existed?
It would be a very George Lucas moment, if Ingenuity were the nearest available 'rover.'
'Beep whir boop whir chirp chirp Whir chirp Whirr blip WHIRRRRRRR.'
As actuators and rotors power up, Watney views Phobos and the Sun.
And sighs.
'Let's get you closer to C3PO.'
The hard part would be getting to Percy. Though it’d be kinda hilarious to approach that rover all “Yo Percy, I’m stranded. Mind sending NASA a video to tell em I’m with ya?” Lol
@@FinkipGirl any idea the distance between where Mark is and the rover is currently? I can't find it lol
Both book and movie were way way too "Indiana Jones"-ish, but apart from that, a great read and a great view. Uhhh, there are no GPS sats around Mars, the precision navigating that he did ON HIS OWN was at best. at best, "highly improbable".
You mean using a map?
The hub has a beacon that works in the same vain like a vor/dme Station works on Earth. It gives Watney a bearing and distance from the hub in line of sight, with a very good precision (i calculated 300m at the horizon 9 km away). Outside of that, you would just use topography and Odometry (measuring the distance travelled by the amount the wheels turned). If you want to see a whole bunch of examples of such rovers working, there is the currently running European Rover Challenge, where students make rovers that CAN'T use gps and they are still able to do (at least some parts *flashbacks to epfl today* ) autonomously
3:15 chtuia just point the camera
Are you receiving me? "no"
I've watched this movie several times and really enjoyed it; but, it bothers me that all this equipment is there before the crew arrives. I mean, the tires on the rover alone probably weigh in at 500-1000 pounds and there were two of them. Just how many rockets did NASA send with equipment/supplies before the crew, and how did they get everything put together in their initial 30 days on the planet? It wouldn't have been feasible to send everything already put together.
Yep I'm with you.
I'm definitely gunna diebig I havec listen to anymore Damnawful freak*ng Disco music.
Been saying that since the late 70's
Interesting that he can just put in the cable of some equipment and it fits in the old rover. Is this realistic?
Is that lab tech "NateTheGreat"
Hey wouldn't you know a. Robot named pathfinder helps people wait a minute where have I heard this before? (Apex legends intensifies)
If they weren't receiving him, the camera wouldn't move, so no is redundant.
I was watching it the other day and said the exact same thing.
@@thedundronian6164 I'd say the book concurred. It just had two signs. "Are you receiving?" "Point here for yes." Not that I'm complaining; both the book and the movie were exceptionally well done, and I recommend both.
Most movie goers aren't as astute as you.
