What We Learned from Flying a Helicopter on Mars

The Ingenuity Mars Helicopter made history – not only as the first aircraft to perform powered, controlled flight on another world – but also for exceeding expectations, pushing the limits, and setting the stage for future NASA aerial exploration of other worlds.

Built as a technology demonstration designed to perform up to five experimental test flights over 30 days, Ingenuity performed flight operations from the Martian surface for almost three years. The helicopter ended its mission on Jan. 25, 2024, after sustaining damage to its rotor blades during its 72nd flight.

So, what did we learn from this small but mighty helicopter?

We can fly rotorcraft in the thin atmosphere of other planets.

Ingenuity proved that powered, controlled flight is possible on other worlds when it took to the Martian skies for the first time on April 19, 2021.

Flying on planets like Mars is no easy feat: The Red Planet has a significantly lower gravity – one-third that of Earth’s – and an extremely thin atmosphere, with only 1% the pressure at the surface compared to our planet. This means there are relatively few air molecules with which Ingenuity’s two 4-foot-wide (1.2-meter-wide) rotor blades can interact to achieve flight.

Ingenuity performed several flights dedicated to understanding key aerodynamic effects and how they interact with the structure and control system of the helicopter, providing us with a treasure-trove of data on how aircraft fly in the Martian atmosphere.

Now, we can use this knowledge to directly improve performance and reduce risk on future planetary aerial vehicles.

Creative solutions and “ingenuity” kept the helicopter flying longer than expected.

Over an extended mission that lasted for almost 1,000 Martian days (more than 33 times longer than originally planned), Ingenuity was upgraded with the ability to autonomously choose landing sites in treacherous terrain, dealt with a dead sensor, dusted itself off after dust storms, operated from 48 different airfields, performed three emergency landings, and survived a frigid Martian winter.

Fun fact: To keep costs low, the helicopter contained many off-the-shelf-commercial parts from the smartphone industry - parts that had never been tested in deep space. Those parts also surpassed expectations, proving durable throughout Ingenuity’s extended mission, and can inform future budget-conscious hardware solutions.

There is value in adding an aerial dimension to interplanetary surface missions.

Ingenuity traveled to Mars on the belly of the Perseverance rover, which served as the communications relay for Ingenuity and, therefore, was its constant companion. The helicopter also proved itself a helpful scout to the rover.

After its initial five flights in 2021, Ingenuity transitioned to an “operations demonstration,” serving as Perseverance’s eyes in the sky as it scouted science targets, potential rover routes, and inaccessible features, while also capturing stereo images for digital elevation maps.

Airborne assets like Ingenuity unlock a new dimension of exploration on Mars that we did not yet have – providing more pixels per meter of resolution for imaging than an orbiter and exploring locations a rover cannot reach.

Tech demos can pay off big time.

Ingenuity was flown as a technology demonstration payload on the Mars 2020 mission, and was a high risk, high reward, low-cost endeavor that paid off big. The data collected by the helicopter will be analyzed for years to come and will benefit future Mars and other planetary missions.

Just as the Sojourner rover led to the MER-class (Spirit and Opportunity) rovers, and the MSL-class (Curiosity and Perseverance) rovers, the team believes Ingenuity’s success will lead to future fleets of aircraft at Mars.

In general, NASA’s Technology Demonstration Missions test and advance new technologies, and then transition those capabilities to NASA missions, industry, and other government agencies. Chosen technologies are thoroughly ground- and flight-tested in relevant operating environments — reducing risks to future flight missions, gaining operational heritage and continuing NASA’s long history as a technological leader.

You can fall in love with robots on another planet.

Following in the tracks of beloved Martian rovers, the Ingenuity Mars Helicopter built up a worldwide fanbase. The Ingenuity team and public awaited every single flight with anticipation, awe, humor, and hope.

The first mobile phone call was made on this day in 1973. Martin Cooper, using a prototype of the Motorola DynaTAC, placed a call from the streets of New York to Bell Labs in New Jersey. The device was 9 inches tall, had a talk-time of 35 minutes, and took 10 hours to recharge.

How I learned to write smarter, not harder

(aka, how to write when you're hella ADHD lol)

A reader commented on my current long fic asking how I write so well. I replied with an essay of my honestly pretty non-standard writing advice (that they probably didn't actually want lol) Now I'm gonna share it with you guys and hopefully there's a few of you out there who will benefit from my past mistakes and find some useful advice in here. XD Since I started doing this stuff, which are all pretty easy changes to absorb into your process if you want to try them, I now almost never get writer's block.

The text of the original reply is indented, and I've added some additional commentary to expand upon and clarify some of the concepts.

As for writing well, I usually attribute it to the fact that I spent roughly four years in my late teens/early 20s writing text roleplay with a friend for hours every single day. Aside from the constant practice that provided, having a live audience immediately reacting to everything I wrote made me think a lot about how to make as many sentences as possible have maximum impact so that I could get that kind of fun reaction. (Which is another reason why comments like yours are so valuable to fanfic writers! <3) The other factors that have improved my writing are thus: 1. Writing nonlinearly. I used to write a whole story in order, from the first sentence onward. If there was a part I was excited to write, I slogged through everything to get there, thinking that it would be my reward once I finished everything that led up to that. It never worked. XD It was miserable. By the time I got to the part I wanted to write, I had beaten the scene to death in my head imagining all the ways I could write it, and it a) no longer interested me and b) could not live up to my expectations because I couldn't remember all my ideas I'd had for writing it. The scene came out mediocre and so did everything leading up to it. Since then, I learned through working on VN writing (I co-own a game studio and we have some visual novels that I write for) that I don't have to write linearly. If I'm inspired to write a scene, I just write it immediately. It usually comes out pretty good even in a first draft! But then I also have it for if I get more ideas for that scene later, and I can just edit them in. The scenes come out MUCH stronger because of this. And you know what else I discovered? Those scenes I slogged through before weren't scenes I had no inspiration for, I just didn't have any inspiration for them in that moment! I can't tell you how many times there was a scene I had no interest in writing, and then a week later I'd get struck by the perfect inspiration for it! Those are scenes I would have done a very mediocre job on, and now they can be some of the most powerful scenes because I gave them time to marinate. Inspiration isn't always linear, so writing doesn't have to be either!

Some people are the type that joyfully write linearly. I have a friend like this--she picks up the characters and just continues playing out the next scene. Her story progresses through the entire day-by-day lives of the characters; it never timeskips more than a few hours. She started writing and posting just eight months ago, she's about an eighth of the way through her planned fic timeline, and the content she has so far posted to AO3 for it is already 450,000 words long. But most of us are normal humans. We're not, for the most part, wired to create linearly. We consume linearly, we experience linearly, so we assume we must also create linearly. But actually, a lot of us really suffer from trying to force ourselves to create this way, and we might not even realize it. If you're the kind of person who thinks you need to carrot-on-a-stick yourself into writing by saving the fun part for when you finally write everything that happens before it: Stop. You're probably not a linear writer. You're making yourself suffer for no reason and your writing is probably suffering for it. At least give nonlinear writing a try before you assume you can't write if you're not baiting or forcing yourself into it!! Remember: Writing is fun. You do this because it's fun, because it's your hobby. If you're miserable 80% of the time you're doing it, you're probably doing it wrong!

2. Rereading my own work. I used to hate reading my own work. I wouldn't even edit it usually. I would write it and slap it online and try not to look at it again. XD Writing nonlinearly forced me to start rereading because I needed to make sure scenes connected together naturally and it also made it easier to get into the headspace of the story to keep writing and fill in the blanks and get new inspiration. Doing this built the editing process into my writing process--I would read a scene to get back in the headspace, dislike what I had written, and just clean it up on the fly. I still never ever sit down to 'edit' my work. I just reread it to prep for writing and it ends up editing itself. Many many scenes in this fic I have read probably a dozen times or more! (And now, I can actually reread my own work for enjoyment!) Another thing I found from doing this that it became easy to see patterns and themes in my work and strengthen them. Foreshadowing became easy. Setting up for jokes or plot points became easy. I didn't have to plan out my story in advance or write an outline, because the scenes themselves because a sort of living outline on their own. (Yes, despite all the foreshadowing and recurring thematic elements and secret hidden meanings sprinkled throughout this story, it actually never had an outline or a plan for any of that. It's all a natural byproduct of writing nonlinearly and rereading.)

Unpopular writing opinion time: You don't need to make a detailed outline.

Some people thrive on having an outline and planning out every detail before they sit down to write. But I know for a lot of us, we don't know how to write an outline or how to use it once we've written it. The idea of making one is daunting, and the advice that it's the only way to write or beat writer's block is demoralizing. So let me explain how I approach "outlining" which isn't really outlining at all.

I write in a Notion table, where every scene is a separate table entry and the scene is written in the page inside that entry. I do this because it makes writing nonlinearly VASTLY more intuitive and straightforward than writing in a single document. (If you're familiar with Notion, this probably makes perfect sense to you. If you're not, imagine something a little like a more contained Google Sheets, but every row has a title cell that opens into a unique Google Doc when you click on it. And it's not as slow and clunky as the Google suite lol) When I sit down to begin a new fic idea, I make a quick entry in the table for every scene I already know I'll want or need, with the entries titled with a couple words or a sentence that describes what will be in that scene so I'll remember it later. Basically, it's the most absolute bare-bones skeleton of what I vaguely know will probably happen in the story.

Then I start writing, wherever I want in the list. As I write, ideas for new scenes and new connections and themes will emerge over time, and I'll just slot them in between the original entries wherever they naturally fit, rearranging as necessary, so that I won't forget about them later when I'm ready to write them. As an example, my current long fic started with a list of roughly 35 scenes that I knew I wanted or needed, for a fic that will probably be around 100k words (which I didn't know at the time haha). As of this writing, it has expanded to 129 scenes. And since I write them directly in the page entries for the table, the fic is actually its own outline, without any additional effort on my part. As I said in the comment reply--a living outline!

This also made it easier to let go of the notion that I had to write something exactly right the first time. (People always say you should do this, but how many of us do? It's harder than it sounds! I didn't want to commit to editing later! I didn't want to reread my work! XD) I know I'm going to edit it naturally anyway, so I can feel okay giving myself permission to just write it approximately right and I can fix it later. And what I found from that was that sometimes what I believed was kind of meh when I wrote it was actually totally fine when I read it later! Sometimes the internal critic is actually wrong. 3. Marinating in the headspace of the story. For the first two months I worked on [fic], I did not consume any media other than [fandom the fic is in]. I didn't watch, read, or play anything else. Not even mobile games. (And there wasn't really much fan content for [fandom] to consume either. Still isn't, really. XD) This basically forced me to treat writing my story as my only source of entertainment, and kept me from getting distracted or inspired to write other ideas and abandon this one.

As an aside, I don't think this is a necessary step for writing, but if you really want to be productive in a short burst, I do highly recommend going on a media consumption hiatus. Not forever, obviously! Consuming media is a valuable tool for new inspiration, and reading other's work (both good and bad, as long as you think critically to identify the differences!) is an invaluable resource for improving your writing.

When I write, I usually lay down, close my eyes, and play the scene I'm interested in writing in my head. I even take a ten-minute nap now and then during this process. (I find being in a state of partial drowsiness, but not outright sleepiness, makes writing easier and better. Sleep helps the brain process and make connections!) Then I roll over to the laptop next to me and type up whatever I felt like worked for the scene. This may mean I write half a sentence at a time between intervals of closed-eye-time XD

People always say if you're stuck, you need to outline.

What they actually mean by that (whether they realize it or not) is that if you're stuck, you need to brainstorm. You need to marinate. You don't need to plan what you're doing, you just need to give yourself time to think about it!

What's another framing for brainstorming for your fic? Fantasizing about it! Planning is work, but fantasizing isn't.

You're already fantasizing about it, right? That's why you're writing it. Just direct that effort toward the scenes you're trying to write next! Close your eyes, lay back, and fantasize what the characters do and how they react.

And then quickly note down your inspirations so you don't forget, haha.

And if a scene is so boring to you that even fantasizing about it sucks--it's probably a bad scene.

If it's boring to write, it's going to be boring to read. Ask yourself why you wanted that scene. Is it even necessary? Can you cut it? Can you replace it with a different scene that serves the same purpose but approaches the problem from a different angle? If you can't remove the troublesome scene, what can you change about it that would make it interesting or exciting for you to write?

And I can't write sitting up to save my damn life. It's like my brain just stops working if I have to sit in a chair and stare at a computer screen. I need to be able to lie down, even if I don't use it! Talking walks and swinging in a hammock are also fantastic places to get scene ideas worked out, because the rhythmic motion also helps our brain process. It's just a little harder to work on a laptop in those scenarios. XD

In conclusion: Writing nonlinearly is an amazing tool for kicking writer's block to the curb. There's almost always some scene you'll want to write. If there isn't, you need to re-read or marinate.

Or you need to use the bathroom, eat something, or sleep. XD Seriously, if you're that stuck, assess your current physical condition. You might just be unable to focus because you're uncomfortable and you haven't realized it yet.

Anyway! I hope that was helpful, or at least interesting! XD Sorry again for the text wall. (I think this is the longest comment reply I've ever written!)

And same to you guys on tumblr--I hope this was helpful or at least interesting. XD Reblogs appreciated if so! (Maybe it'll help someone else!)

do you ever think about Humans, even humans who don’t like glitter, like glitter. We are drawn to shiny things in the same wild way our ancestors were overcome by a compulsion to forage for honey. A theory that has found favor among research psychologists (supported, in part, by a study that monitored babies’ enthusiasm for licking plates with glossy finishes) is that our attraction to sparkle is derived from an innate need to seek out fresh water. I'm at the beach and it is 27 degrees celsius and the water is glittering glittering glittering
