They only had enough fuel to land on Mars for the original mission in the lander and then go back to the ship once; fuel is heavy so they only have enough to use within a fairly limited budget.

I once played a very minor part of the Mars Pathfinder mission's success. Pathfinder itself was the lander that also transported the Sojourner rover (the first one ever sent to Mars). During the cruise part of the mission JPL asked the spacecraft to take more images of asteroids than was in the original mission plan, so the lander's memory became more cluttered with "stuff". This led to the operating system (vxWorks) becoming more busy and eventually triggering priority inversion events which the watchdog hardware had to recover by resetting the onboard computer too much. For some reason JPL did not actually enable the priority inversion prevention feature already built into vxWorks, which required a memory patch by remote control from millions and millions of miles away. Eventually that worked, so yay. Nothing wrong happened to the Sojourner rover except the expected freezing of the wheels and loss of power from the solar panels. I was working at Wind River (the maker of the vxWorks OS) at the time and really was extremely motivated to help make everything work as much as I could.

I love The Martian, it's an excellent feel-good science fiction film and my favourite film of 2015.

This is a terrific movie, I never get tired of seeing fresh reactions to the science and the sense of humor.

This is very much like a desert island movie in space it's wonderful.

They wouldn't have enough fuel to: lift off from Mars, fly around, land, then lift off again.

6:48 Sol means sun... it is the name of our star, the sun..as in solar. SOL in the movie = 1 full rotation of Mars or 1 Mars day

In actuality, Mar's atmosphere is so thin, you wouldn't even feel it, and trying to steer yourself using the thrust of a hole in your suit is criminally stupid. Other than that, most of the rest of the movie is pretty scientifically accurate.

Matt Damon also starred in Good Will Hunting, Saving Private Ryan, and The Talented Mr. Ripley, as well as Ocean's Eleven.

This film was nominated for a comedy award 😂 at the Golden Globes even tho it was made as a drama Sci-fi

The man who shoots the arrow 🏹 through the axes 🪓 before the movie is Odysseus. From Platos the Odyssey ⛵️

You are a very wise and intelligent people. Thank you both for the content.

Related to 21:40: I haven't seen the movie, but I gather they didnt include that bit fom the book that whatever happened, Johansson would survive. Read the book if you want to know!

Another great Ridley Scott movie! 50 years ago, Ridley gave us Alien. Now this!

I was well surprised after the drop of a hundred (?) or more micro sats to see see India enter the game.Then again, any heavy lift rocket is more than welcome.Also, dope moon lander.

some classic space expo movies would be "2001: A Space Odyssey" ( 1968) "2010: The Year We Make Contact" (1984) provides answers to the questions raised in 2001

I’m not sure of your names, but I definitely recommend reading the book. The movie is an excellent adaptation, but there are more details in the book. I think the man in particular would enjoy it.

One of the earliest (cerebral) Sci-Fi movies I recall being obsessed with is Silent Running (1972) starring Bruce Dern. It has the general vibe that a lot of pre-Star Wars science fiction had in the early 1970s and a message that was rooted in the culture of the era when it was produced. Sorry, I can't be more specific without risk of spoiling things, but it would be a great movie to react to.

great job, guys, thanks for the reaction, this is a really cool movie!

This is the second youtube channel ive seen that does movie reactions. And let me tell you you guys know how to watch and enjoy a movie so gripped constantly praising the characters for there smarts. Its great cant wait to watch more. SUBSCRIBED!

Such a fun movie with a great and unexpected soundtrack.

Great reaction ❤

This is a definite top 10 sci fi movie on my list . Also, Please do a Blood in Blood out movie reaction . You won't regret it's a cult classic

5:01 - 5:07 lol

I hope to see people on Mars in our lifetime.

Caught that huh? The answer is no, just planting potatoes with human waste as fertilizer in mars dirt would not work. Time constraints for the movie, but in the book what he did was he used the small amount of earth soil they brought with them for experiments to mix with mars dirt. So that the organisms in the earth soil would propagate into the mars dirt. And then he just kept doubling it, over and over, until he had enough to farm. Also, the scientific accuracy in the book was seemingly very high, aside from the thing that caused him to get stranded there. The atmosphere of Mars is way too thin to allow for winds like that. There wouldn’t be wind storms powerful enough to tip their MAV (Mars ascent vehicle)

"Remove everything." "You're horny?" 😆

Mrs Singh could be an Astronaut if she wants too 🤗

They are struggling for their lives This girl: "KISS KISS"💀

You guys should watch the movie Wall-E

wow this guy said more words in this than what the movie had

Mars is almost half the size of Earth so yes he would weigh about a 3rd of what he would on Earth.

The book and movie are a love letter to science. Except for the opening storm; that doesn’t happen on Mars. The atmosphere is too thin, 1% of earth’s

We are grooooooot! 😊👍

Moon gravity 1/6th of earth. Mars gravity is 1/3rd of earth, so 100 pounds on earth would weigh about 33 pounds on Mars.

If you read, read this book. There are differences.

one of the few realistic fantasy films.

I would play Cricket with you on mars bro - it would be the first India versus Australia match on the planet lol - Winner is literally world champion of Mars xD

Gravity on Mars is 1/3 of earth

Try a real Steel movie 😊

NO STORMS ON MARS. There's no atmosphere

“Gravity”

It’s odd that I need to remind people of this, but SpaceX hasn’t left lower orbit.

In the book Mark wrote "Boobies!"

Japan not China

No, not for real. There's lots of scientific inaccuracies. But it's a fun story.

How many women will filter through this show by the time it’s all done

I hope there's pizza on mars

The ending is the funniest scifi ending I've ever seen. Lost all the respect the rest pf the movie gained. If you really want to see what REAL scifi looks like watch The Expanse show. It's the greatest tv show ever created. (not just best scifi show).
