5 NASA Software Codes You Can Download – For Free!

One of the biggest steps of any mission starts right here on Earth at a computer desk – NASA runs on software, period. Rovers can’t move, spacecraft can’t fly, even rockets can’t blast off without the software codes that run them all.

We’ve compiled hundreds of these powerful codes into one location at And guess what? You can start downloading them right now for free! Here are just a few you can use:  

1. TetrUSS (Tetrahedral Unstructured Software System)

TetrUSS has been used extensively for space launch vehicle analysis and design, like on the Space Launch System, which is planned to take humans to Mars.

You really could say it’s helping us to “blast off.” Outside of NASA, this software has been used to analyze Mars planetary entry vehicles, ballistics and even high-altitude sky diver aerodynamics. Basically if anything has moved through any planetary atmosphere, this software has played a role.

2. KNIFE (part of the FUN3D software and released as a package)

The name may be a bit intimidating, but with good reason – KNIFE packs a powerful punch. 

It was created to help us learn more about the sonic booms that resonate when planes break the sound barrier, but it has also helped develop green energy sources such as wind turbines and techniques to minimize drag for long-haul trucking. Maybe we should re-name this versatile and handy code, “Swiss Army KNIFE?”

3. Cart3D (Automated Triangle Geometry Processing for Surface Modeling and Cartesian Grid Generation)

If software codes went to high school, Cart3D would be Prom Queen. This software is so popular, it is being used in almost every mission area here at NASA. 

Engineers and scientists are currently using it to model everything from advanced drones to quieter supersonic aircraft.

4. FACET (Future Air Traffic Management Concepts Evaluation Tool)

Frequent flyers: this may be your favorite code without even knowing it. FACET was developed to evaluate futuristic concepts in air traffic management, and it has served as a testbed for assessing today’s regular operations. 

To sum it up, this software code helps airports keep planes organized in the air and on the ground.


GIPSY-OASIS is part of the GPS system to end all GPS systems. It’s so accurate, John Deere used it to help create self-driving tractors.

 How? John Deere already had a navigation system in the works, but it could only be used in certain parts of the world. 

Our ground stations are all across the globe, and our software ensures accuracy down to a few inches. And so, a new breed of tractor was born!  Did we mention this software is free?

These are just a few examples of the software NASA has available for free public and consumer use. To browse the catalog online, check out

For those who don’t know us: we’re a group of fans who love the Netflix original serie Voltron legendary defenders. A few months ago, with the support of different artists from the Voltron fandom, we did a fan made coloring book, it’s free and you can download it here.

Now after the success of the first coloring book and the suggestions of some people we are thinking of doing a second edition of the book. but for this we want to know if there are people interested in a second part and if there are new artists interested in participating.

We would love to do a new coloring book so please guys let us know If you are interested in a new coloring book.

How to make a functional school without mod (V2.0.)

A few months ago I’ve made an article about how to have a functional school without mod. I’ll do it again with more indications and tips from my gameplay experience. While you’re reading this, keep in mind the game has an usual limitation of 20 sims per community lot for performance purpose. If you want more students in your school, you’ll need mods. As a cc-free player, I don’t use these so I’ll just show you my way.

First of all, you’ll need to create groups of pupils with an age restriction (>> for kids only). The best option is to create up to 4 groups with 6 kids in each. I encourage you to pick group leaders from different households. If you don’t, you decrease your chance to have groups showing up while you’re playing… Except if all the leaders are in the household you want to play with. But when kids turn into teens, the leadership goes most likely to a younger relative (siblings, cousins…), so please don’t forget that.

The reason why you better chose leaders from different households is because the game system works on rotation : not the same households are “active” during your game. Also, do not put all the siblings in the same group if you’re not controling it. There’s high chance none of them show up to make room for others. So if you have triplets, place them in 2 or 3 differents groups ! Same for twins or cousins who live at the same place :)

When you’ve chose the leaders, add 5 kids in their group. You must pick for them a favorite location : chose the school you’ve downloaded.

Now, time to assign them tasks. Pick wisely: you only have 5 options. Know that the order you put them is important ! First task is the one they’ll do automatically ; Second task is the one they’ll most likely do ; Third task is the one they’ll do during breaks ; Fourth task is the one they’ll do if there’s too much other sims somewhere ; Fifth task is what they’ll do if they do not have other choices. And last but not least, the group will behave the way the community lot is set up if they don’t have any options left.

For example, if in your school there’s no jungle gym and your first task is to play with playground equipements, the kids group will try to play with toys (if it’s your task number 2). If there’s no toys left, they’ll try to chose option 3, and then option 4 etc. The group system works like a staircases.

Because you’ve made 4 groups and there’s 4 aspirations for kids (now), chose tasks according to this. Make a “creativity” group, a “social” group, a “motor” group and a “mental” group. In my game, all the groups have something in common (task 2 : do their homework). And the other tasks are “custom” for each. This way, kids won’t go in the same room instantly but walk around and do different stuff.

Task suggestions :

  • Mental group : 1. Play with computer. 2. Do homework. 3….
  • Social group : 1. Be nice to… 2. Do homework. 3…
  • Creativity group : 1. Paint. 2. Do homework. 3….
  • Motor group : 1. Play with playground equipements. 2. Do homework….

Because my school is set as a library, all the groups can possibly chose to read and browse the web. The option 5 can be a task opposite to their trait, for example the creativity group can play basketball. There’s multiple way to do it so go with your flow !

You can also set up group for teachers (up to 3, max). Assign them the school as their favorite location and tasks. If you have City Living EP, chose “make speech” as an option. A few kids will actuall listen to them ;)

If you want to go extra, you can also make a cook group (up to 2, max), assigned them uniforms, the school as favorite location and task (cook / clean). Chose sims with low cooking skill so they can do basic reciepes and not gourmet meals. ;) Same for a janitor (you can make a group of only 1 sims !). 

With all that, everytime you load your game you’ve really high chances to meet pupils, teachers and cooks, janitor. Since I’ve create this system I always have people in my school and everything works smooth ! Keep in mind that random townies can still show up in your school (because it’s a library, you know…) but they’ll leave if more groups come, to make room for them. 

Notes :

  • A kid can be in multiple groups (ex. motor + creativity). You won’t get any negative effects. His/her chance to actually show up is only higher than others kids.
  • If the cook team don’t show up and you still want your sims to eat for a possible lunch break : click on the hoven’s kitchen and call for a caterer. He or she will usually make up to 3 or 4 differents group meals. Put each plates on different lunch tables and call to meal. All the groups should pick a plate, sit and chat to each others. The only “bad” effect with the caterer option, is that they’ll most likely make gourmet meals…
  • You can chose an option to make cooks shout at children faces. Go to social >> Be mean to… >> Chose a group or a life state.
  • To increase your chance of groups interacting, make the option 4 “be nice to / be funny to / be mean to… >> this group”
  • Adult can automatically teach kids some skill (piano, violin, painting, basketball etc.) if they see kids use these objects. For this, your adult need to be level 10. If your teachers have 10 at one skill, they’ll most likeky try to teach to a kid something…
  • If you want them to be in a private school, assigned them a uniform. Please, note that the sims need to be in their everyday wear to turn into their uniform clothes. They can “lose” their uniform if they turn into their sport wears (for example, if they use the basketball hoop). If so, go talk to them and chose the interaction : “show me your… >> everyday outfits” Then the sims will get his uniform back.
  • To go further… You have the possibility to make smaller group for extra activities like drawing, basketball etc. and assigned them uniforms, lock the doors and only them will go there.
  • If you want to avoid townies break in during class, put all the computers somewhere else. Same for the bookshelves !
