We’re pushing forward with our plans to roll out the WeMartians travel grant. It’s an opportunity for the WeMartians community to give back to the STEM community by funding students to travel to conferences. Last month we visited the Lunar and Planetary Science Conference this month and have seen first-hand how beneficial it can be. You can read more about our ideas for the grant in our recent explainer post. But to get there, we need your help!

Thanks to all the Patrons who’ve pledged support already, especially our Station-Level and higher donors. We’re already 79% of the way to our goal of $450/month to kick off the WeMartians Travel Grant. This is so close! I would love to see this goal reached by the summer time so that we can get this project moving!

Well Martians, we’re down to the final week! NASA’s InSight mission to Mars lifts off early Saturday morning and we’re travelling down to watch the event and cover it for you. Here’s what you can expect over the next week!

Twitter Previews

Beginning today, there’s an extensive Twitter preview of the mission happening over on our feed. Each day until Friday, we’re covering aspects of the mission in a shareable Twitter-thread format.

  • Monday (April 30th) – Why InSight? Science Objectives
  • Tuesday (May 1st) – History of the Mission
  • Wednesday (May 2nd) – The Spacecraft
  • Thursday (May 3rd) – The Science Instruments
  • Friday (May 4th) – The Rocket & the Launch

Pre-Launch Briefing

At 1PM PDT/4PM EDT on May 3rd, NASA will hold a Pre-Launch Briefing that we will be covering over Twitter. The briefing will be live-streamed on NASA TV.

Launch Day

InSight launches at 4:05AM PDT from Vandenberg Air Force Base. We’ll be in Lompoc, California outside the base looking for the best place to view the launch from. It becomes tricky balancing the desire to be close, but the desire to be high enough to avoid the infamous Vandenberg Marine Layer fog, which often blankets the area and can block your view of the rocket.

Once we find a spot we’ll be sure to do some Periscoping on Twitter!

ULA’s Space Launch Complex 3E, where InSight will lift off from on an Atlas V rocket on May 5th.

The Podcast

Episode 41 will cover the story of InSight, from its humble beginnings, through it’s launch. We’re completing research this week, collecting audio on-site, and producing the episode early next week. Look for it in the WeMartians feed as early as Wednesday the 9th of May!

Patreon Perks

If you’re one of our Patreon Supporters, I’m going to be making an attempt to use Patreon’s new Lens feature to provide live video updates through the trip. This will be a nice low-overhead way for me to give you some closer looks at what’s going on.

I’ll be in the Off-Nominal Discord on Thursday for the Pre-Launch Briefing. You’ll also get at least one audio update with some early thoughts on the launch which I hope to get up quickly. I’ve also got some other goodies in store for you.

Periodically, scientific discoveries at Mars prompt new thinking and paradigm shifts in the way we perceive the Red Planet. If these changes are significant enough, it merits an adjustment to our strategy when we explore. One such topic up for discussion is the importance of Mars polar science, or the study of the poles. The Mars Exploration Program Analysis Group discussed this at their committee meeting last week in Crystal City, Virginia.

Side note: we also discussed the MEPAG meeting in our most recent episode of Red Planet Review. It’s a weekly podcast available for our $3+ patrons discussing Mars headlines. Listen to the sample episode here or follow the link below to pledge support!

Who or what is MEPAG?

MEPAG (or Mars Exploration Program Analysis Group) is a community-led committee that informally advises NASA on scientific goals for the exploration of Mars. The community maintains a goals document, which is a summary of the questions that are high priority for investigations. MEPAG forwards this document to the formal NASA advisory bodies or departments, like the Mars Exploration Program, the Planetary Science Advisory Committee or even the Human Exploration and Operations Mission Directorate. Really, it’s main goal is to ensure the Planetary Science community has a say in what NASA does next at Mars. Here are the four major components of the current goals document.

  1. Determine if Mars ever supported life
  2. Understand the processes and history of climate on Mars
  3. Understand the origin and evolution of Mars as geological system
  4. Prepare for human exploration

The four primary goals of Mars Exploration, as outlined by MEPAG

What’s prompting a change to these goals?

In late 2016, the Lunar and Planetary Institute (the same body which organizes LPSC) hosted the Sixth International Conference on Mars Polar Science and Exploration in Reykjavik, Iceland. Scientists from different disciplines studying both Earth and Mars joined forces to share current results, outstanding questions, and future priorities. One hundred and two highly engaged attendees from 11 countries participated. It became clear that Mars Polar Science was both very important not well represented in NASA’s current goals and objectives. So, the community sought to change that.

Early in 2017, the community published a report that was a summary of the conference and a presentation of five main scientific questions that the Polar science community wants answers for. This was the first step in instituting change in the scientific direction of NASA’s Mars program.

Why is polar science important?

Planetary scientists sometimes overlook polar science. It’s part geology and part climate, which makes it challenging to study by someone from only one discipline. However, this dual-nature also makes it especially important to study because it has such global reach in the formation of today’s Mars.

Every year, when the poles are in their winter season and fully enveloped in darkness, upwards of 30% of the carbon dioxide in the atmosphere condenses on the surface, forming metre-thick layers of frost. In the summer, it sublimates back in to the atmosphere and the cycle repeats. That’s a dramatic amount of change for Mars’ atmosphere. With it comes a multitude of planetary wide changes, including cloud formations, dust movement and temperature changes. This movement of CO2 drives the Martian climate.

Each seasonal cycle leaves a layer of dust and debris on the layered deposits of the poles, preserving a record of the past seasons like rings in a tree trunk. The data in the layers of the poles are invaluable in understanding Mars’ past climate. These data can then be correlated with the geologic record to understand and confirm theories on how the planets features were formed. We might think, for example, that a certain feature on Mars could be formed if temperatures were sufficiently high, but have no way to confirm that geologically. Climate studies help geology and vice versa.

From the summary report:

The poles are a record of past climate, and polar processes drive current climate. The poles influence movement of sand in dunes, dust in the atmosphere, isotopic ratios, availability of volatiles, melting point and stability of liquid water – through time.

What’s next?

The committee has taken the report from the Polar Science Conference and incorporated them into a proposal to change MEPAG’s goals document. This is a great step and the final proposal will be available this summer. A public consultation period will be available prior to finalization. But what does this mean for actual Mars exploration?

You won’t see some kind of polar lander dropping down into Chasma Boreale next launch window. These changes take a long time to propagate through the NASA system. Changes to this document may inform next year’s budget requests for NASA that could theoretically have impacts on funding for current or future missions. But chances are it will have little impact there.

Next year, the 9th International Conference on Mars is being held in Pasadena. It’s an important gathering of Mars scientists that often drives changes to MEPAG’s goals document as well. So, expect to see another revision following that meeting. From there, MEPAG will forward the goals document to the Planetary Science Decadal Survey committee, which formally kicks off in 2020. That’s where a major impact can be made. The Decadal Survey is (as its name implies), a once in a decade guiding document formally requested by NASA to inform its planetary science agenda. The current one expires in 2023. If Mars polar science is as important as its community believes, then maybe we’ll see it codified in the Decadal Survey. If it is, then perhaps we’ll see more missions focused on exploring the amazing and beautiful poles of Mars.

NASA is launching the InSight mission to Mars early in the morning on May 5th, 2018. That’s soon! So we’re ramping up coverage of the spacecraft as the launch nears. Plus, we’ve got an exciting new T-Shirt in our shop to celebrate the start of the mission. But first, what is the InSight mission all about?

Gaining InSights into Mars’ interior

InSight stands for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport. It’s the first spacecraft that will primarily measure what’s happening inside the planet Mars rather than what’s shaping its surface. InSight is part of NASA’s Discovery program, the smallest of the three classes of planetary missions the agency funds.

To accomplish its mission. InSight will use two primary instruments. The first is SEIS (Seismic Experiment for Interior Structure). It’s a super-sensitive seismometre that InSight will place directly on the surface using its robotic arm. When we say “super-sensitive”, we mean it. The instrument will detect earthquakes (or should we call them marsquakes?) all over the planet. In fact, it’s so sensitive that it will detect the gravity of Mars’ moon Phobos tugging on the surface as it orbits around Mars. In a Von Karman lecture at the Jet Propulsion Laboratory, the principal investigator of the mission Bruce Banerdt said that in testing, SEIS could detect the waves crashing against the California coast. From Colorado. France’s space agency CNES contributed the instrument.

The other major instrument is HP3 (Heat Flow and Physical Properties Package). This fascinating little probe is a self-penetrating spike connected by a long tether. The probe has a spring loaded hammer inside which allows it to slowly burrow downward into the regolith, as deep as five metres. Along its tether are temperature sensors that will allow it to measure the heat escaping from the planet’s core. Like SEIS, InSight’s robotic arm will deploy HP3 directly on the surface. Germany’s space agency DLR contributed the instrument.

Other Instruments

InSight has a number of additional instruments to help with its mission as well. You can read more about them on the Wikipedia page. I would also recommend you listen in to our interview with Farah Alibay, a Payload Systems Engineer at the Jet Propulsion Laboratory, who explained how these instruments were integrated into the spacecraft and what kinds of things they can accomplish.

How will InSight get to Mars?

InSight is launching from Earth onboard a United Launch Alliance (ULA) Atlas V rocket in the 401 configuration. That means it has a 4-metre fairing, 0 solid rocket boosters, and 1 Centaur upper stage engine. Here’s a breakout of the spacecraft and the rocket components in an exploded view.

InSight’s launch is scheduled for May 5th, 2018 at 04:05 AM PDT (11:05 UTC). It’s lifting off from Space Launch Complex 3 at Vandenberg Air Force Base on the West coast of the United States, in California. This is the very first launch of a planetary mission from Vandenberg. Normally, these missions fly from Florida to take advantage of the speed boost from launching due East. But InSight is a relatively light spacecraft and the Atlas V is a mighty rocket which can make up for that advantage, and so to avoid congestion at Kennedy Space Centre, it’s heading south from the California coast. If the skies are clear and you get up really early, you might be able to see the rocket from Los Angeles or even as far South as San Diego. If not, you can watch the stream on JPL’s YouTube channel.

Should there be any issues with the launch, the window extends for two hours, giving the opportunity to recycle the countdown and try more than once. Even if the window is exceeded on May 5th, they can try again every day at roughly the same time until as late as June 8th. Once the rocket lifts off, it will go through a nominal sequence to enter an Earth parking orbit before heading off on an interplanetary trajectory. The first stage and the protective aerodynamic fairings will fall in to the ocean, and the second stage (Centaur) will take InSight off in to deep space. It’ll be quite a ride.

MarCO A and B

After InSight separates from the Centaur upper stage, two smaller spacecraft called cubesats will deploy from something called the Centaur Aft Bulkhead Carrier (ABC). The ABCs are two small compartments underneath the stage next to the engine. Here’s a diagram to show you where they are stowed.

These cubesats, called MarCO A and B, will travel independently to Mars. It’s kind of like formation flying, though the spacecraft will likely separate to large distances en route. Once everyone arrives in November, the MarCO sats will act as relay satellites, sending data from the InSight lander directly back to Earth. MarCO is an experiment to see if cubesats can play an important role in planetary exploration, and it helps takes the load off the lander and the existing orbiters at Mars.

WeMartians Coverage of InSight

Jake is heading down to California for the launch. We’re still awaiting confirmation of media credentials but he will provide live coverage through Twitter either way. An episode covering the launch event will air the following week in our normal podcast feed.

Travel to events like this is not cheap. It’s made possible thanks to the generous contributions of the WeMartians Patrons over on Patreon. There, they pledge as little as $1/month to gain access to bonus content, our Red Planet Review podcast, advance notice of interviews and the Off-Nominal Discord. It’s a great way to support an independent podcast, and if you pledge now you’ll be ready to access additional content for the InSight launch.

Pledge $1 or more to WeMartians on Patreon to get InSight bonus content

But, if pledging isn’t your thing, though, read on!

Introducing the InSight Launch T-Shirt!

Another way to support WeMartians is by visiting our shop for great Mars apparel. Today we’re launching a special new T-Shirt to celebrate the InSight launch, the first interplanetary launch from California. We tried to capture the feel of the Golden State in this vintage design as well as some real science. The wavelength at the bottom of the logo is the typical result of an earthquake on a seismometre, with the p-wave, s-wave and surface waves visible in a row.

Order now to ensure you get your shirt in time for the launch! And don’t worry, we have different colours and sizes in men’s and women’s cuts.

Obviously, we’re very excited for the InSight launch. Mars missions only come around every twenty-six months. So let us know if you’re going to come down for the launch as well or what your thoughts are. Remember, you can tweet or email us. Go Atlas, go Centaur, go InSight!


Late last year we announced our next Patreon goal would be $450/month. When we reach it, we’ll launch a new program called the WeMartians Travel Grant. Following that announcement I promised an in-depth look at my thought process for this grant and what it means to this community. This is that in-depth look.

The program can (and will) change between now and when it formally launches. It’s a work in progress. But I’m a big fan of transparency, especially when it comes to handling money from our listeners. So this is my way of sharing my thoughts and soliciting feedback!

But before we begin…

None of this will matter if we never achieve the goal. We’re sitting a little over 1$100/month short as of this writing. That’s not that much considering the listenership of this show! So if you haven’t signed up to be a patron, this is a great time to think about it. We’ve even done some blog posts to really explain the benefits of the Orbiter Level ($1), Lander Level ($3) and Rover Level ($5). And if you’re feeling really generous, we have $10-$25 levels that give you discounts in our store, a presence on our donor page, and more. So pledge today and help us help a student travel to a conference.

Support WeMartians on Patreon and help a student travel to a conference

Why do this?

Jake with past guest Tanya Harrison at last year’s Lunar and Planetary Science Conference 2017

Most of the episodes you’ve heard on the podcast have been long form interviews with scientists, engineers, & communicators. We have not compensated these guests for their time; they are generous people who want to share their work with the world. These acts represent a culture in space of sharing and teaching, a culture I am deeply grateful for, and one I want to pay forward.

As the WeMartians community continues to grow, I want to make sure that our collective values are something we can be proud of. Supporting the next generation of STEM professionals as they communicate their work is completely in line with this project’s mission statement: to engage the public in the exploration of Mars in a simple, fun, educational and inspiring way. Most importantly, it’s a way for us to invest in the future of Mars exploration. The astronauts who first walk on Mars, whether they be geologists, mechanical engineers, doctors or pilots, may well be studying today.

Why a Travel Grant?

Other ideas considered were simple scholarships or bursaries, but I made the ultimate decision to specifically fund travel for a number of reasons. First, travel to conferences is expensive. I know this first-hand now thanks to the Lunar and Planetary Science Conference. Hotels book up quick, rates are artificially inflated, and registration fees can be high (in the hundreds to even thousands). Throw in meal expenses and it becomes a work week that costs as much as a vacation. If you’re travelling internationally this can be even worse.

The poster session of the Lunar and Planetary Science Conference

Second, in developping this grant, I spoke with some industry professionals and students and learned a lot. Often, grants do not cover conference travel, and many supervisors do not have extra cash to include it. Facing competing priorities of lab work & equipment, fieldwork and you know, salary, travel is often left out.

And here’s the thing. Conference travel is about sharing, networking, and expanding your horizons. Students attending learn valuable skills in connecting with others and presenting their work. What could be more appropriate for a podcast than to fund others communicating their science?

Who would be eligible?

For the first year at least, I’d like to cast a broad net. We welcome undergrads, masters students, PhD students and even post-docs. As long as you’re studying at an accredited post-secondary institution, you’d be eligible.

But what about the topic of your study? Again, the net will be broad. We only stipulate that your field is connected to Mars exploration. This could be directly or indirectly. For science majors, we might fund students studying planetary science, astronomy, astrobiology, geology, space medicine or more. For engineers, we might select students working on developing technology that helps people or robots launch, travel to, communicate back from, or directly observe Mars. This could include propulsion engineers, life support technicians, and instrumentation experts.

The application will ask that you show how your work furthers our understanding of Mars. That’s it!

What about different demographics? Will there be preferences for one over the other?

WeMartians is committed to representing and supporting people from all demographics. Students of any nationality, culture, gender identity, sexuality, religion, ability or ethnicity are welcome and encouraged to apply.

Selections will not be awarded based solely on demographics. However, WeMartians is committed to levelling the playing field by supporting underrepresented groups. Preference will be given to applicants who can demonstrate financial hardship or who are or have been disadvantaged by current or past bias.

Any other special skills?

Science communication inspired this grant. Therefore, applicants who can demonstrate public engagement efforts will earn preference. Whether through public talks, instagram accounts, sciart or community volunteering, we love hearing about your work to engage the public with STEM.

The WeMartians Podcast will offer an episode slot to all awardees to talk about their work and their experience.

How much is the grant?

The final grant amount is still unknown and will probably change year to year based on available funds. WeMartians is entirely listener-supported. Disposable income changes year to year depending on travel schedules, hosting expenses, and equipment needs. In the first two years of the show, WeMartians operated at a loss, which I personally cover.

Once we reach our goal of $450/month, we will also initiate a special limited edition T-Shirt sale with a special design. All proceeds will contribute to the grant. Depending on the speed at which we reach our goal and the volume of shirt sales, the grant amount will change. It is my wish to be able to award at least $500 USD but it is possible it could be more. If the available funds are extraordinary we will also consider breaking up the grant and making multiple awards.

So what’s next?

We’re continuing our drive to $450. This week, we’re at the Lunar and Planetary Science Conference in Houston live-tweeting and blogging all kinds of Mars science. We’ll be interviewing people to hear about their work. And we’ll be making podcasts all about it. If that content is valuable to you, lend a hand and pledge on Patreon or pick up a sweet t-shirt in our shop.

We’d love to hear your feedback on the grant. Make a comment below, tweet us, or send us an email. We’ve done our best to solicit feedback from students and professionals, but at the end of the day academia is something we’re new at. So, we welcome any perspectives that might help make the grant or the selection process better.

Thanks for all your support. I cannot express how excited I am to bring this grant to life.

Six different T-Shirt designs for WeMartians

A selection of T-Shirt designs available on the newly launched WeMartians Shop


Every year in March, nearly two thousand scientists, from geologists to astronomers to geophysicists, descend upon The Woodlands, Texas, a suburb of Houston. And for one week, they share the latest findings in planetary science at the Lunar and Planetary Science Conference (LPSC).

Facilitated by the Lunar and Planetary Institute, who itself is supported by NASA, the 49th annual LPSC promises to showcase a variety of important Mars results, and WeMartians will be there in person to capture it all.

What can I expect for coverage?

TL;DR (if you’re short on time): Follow us on Twitter (@we_martians) for coverage from Monday, Mar 19 to Friday, Mar 23. The conference hashtag is #LPSC2018. First podcast episode will be Tuesday, Mar 27. Additional long form interviews will follow in subsequent episodes on our regular 3-week basis. Patreon Supporters should read below for bonus content info.

Social Media

I am one of the official conference microbloggers with dedicated access to wi-fi during LPSC. If you’re looking to follow along as it happens, our Twitter account is the one account you should follow. This year I’m going to make an attempt for more Twitter live video to bring you inside the science and the event at a deeper level.

Our other channels (Facebook and Instagram) will not have any further content than normal.

The Podcast

Episode 39 will be released on March 27th, the Tuesday after the conference. The intention is for this episode to be an overall story of the event, with short interviews from a variety of attendees and organizers. Listen to this podcast to hear a great summary of the event! This episode should include a good mix of science, inspiration and exploration. We might even be able to catch up with some of our past guests!

Depending on the contacts that we make on site, we could have 1-3 additional episodes that will follow on the regular schedule after Episode 39. These episodes will be traditional long form interviews with one or more scientists who are working on Mars.

Chomping at the bit? Try checking out last year’s summary episode as well!

What if I’m a Patron?

Quite frankly? Fasten your capsule harness. We’ve got a lot in store for Patrons of all levels. Expect daily audio updates throughout the event, and a vast amount of bonus content that doesn’t make it in to the regular episode. If you’re not already a Patron, now would be a great time to join. Bonus content is available to all Patrons who pledge $1 or more per month to help WeMartians continue building great content like this.

If you’re in our Discord (if you’re a $5+ supporter), I’ll be spending some time in there as well to give more inside looks and commentary. This will be a great place to discuss some of the things I see that aren’t suitable for public consumption (sounds lascivious, doesn’t it?!).

The Event Itself

You might be asking yourself – what kinds of things actually happen at LPSC anyway? You can definitely check out the week’s schedule at a glance, or the full schedule with links to the abstracts being presented. But basically, there are three major kinds of events happening.

Oral Sessions

During most of the mornings and afternoons, different presenters will be taking turns giving talks  of around 15 minutes each on the subjects of their papers. These papers are organized into groups of similar research, and similar destinations in the solar system. For example, Monday morning has a three hour session on Mars Polar Caps: Where Ice Lingers, which is a series of talks on Mars’ two polar caps and the amazing processes that shape and change them. If you remember way back in Episode 4, Michael Aye taught us about how Carbon Dioxide cycles to the poles and back seasonally – this would be the right session for a talk like that (in fact, Michael is speaking in this very session!)

We’ll be hitting as many of the Mars ones as possible (hitting all would require Jake to be in more than one place as once). Past guests Lauren McKeown, Michael Aye, Justin Cowart, Matt Golombek and Frances Butcher are all speaking this year. Some of the highlighted sessions I’m looking forward to:

  • Astrobiology I: Looking for Life on Mars, Microbial Impact of Human Exploration, Curation Contamination Measurements
  • Mars Atmosphere
  • Aqueous Alteration of Mars: Results of Rovers, Meteorites and Analogs
  • Mars Rover Results: Depositional and Environmental History

Poster Sessions

If you don’t land a talk to present your work at LPSC, you might also have the chance to present your scientific findings in one of two poster sessions. These happen Tuesday and Thursday evening, and basically involve a huge conference hall with rows of posters up on walls. These posters try to summarize, with figures and other imagery, the findings on various topics so far. These posters are also categorized into different areas based on different themes.

We hope to meet a lot of people in these sessions and capture some on the scene summaries of different work being conducted. Some of the poster categories I’m looking forward to:

  • Astrobiology III: Analog Environments, Life Detection, and Extremophiles
  • Mars2020 Supercam Calibration & Lab Results
  • Planetary Mission Concepts III: Mars
  • Mars Future Exploration and Landing Sites
  • Human Extra Vehicular Activity Research
  • Phobos & Deimos II
  • Community Update from the Mars Exploration Program Advisory Group

Presentations & Special Events

Finally, there are a couple presentations & special events which take place throughout the conference.

On Monday, there is a feature lecture by Linda Spilker on Cassini, which will surely be delightful. Later that evening is “NASA Night”, where members of the Planetary Science directorate will address the attendees. We usually get some great info from this talk. They’re holding another smaller format meeting on Tuesday.

Monday evening, the Exhibit Hall opens, which has some cool visitors we’re keen to say hello to. Oftentimes big aerospace companies like Lockheed Martin will put on displays here.

On Wednesday, we’ll have the chance to hear Apollo astronaut Harrison “Jack” Schmitt present some of his research as a geologist in Taurus Littrow on the Moon, which is of course a treat. More about the 45th anniversary of Apollo 17 will be on the docket later that afternoon.

It’s going to be a blast. So follow up on Twitter and be sure to catch Episode 39 of the podcast the following week!

This is the third part of a series on the WeMartians Patreon program. In January we covered the Orbiter level of $1/month, and last month we talked about the Lander level of $3/month. We’ve set some ambitious goals for the podcast. The most important goal is launching the WeMartians Travel Grant. If I’m serious about hitting these goals this year I need to ensure that the benefits of becoming a patron are clear. It occurs to me that I’ve only ever gone over the rewards at a cursory level. So, with this blog series I hope to change that.

Today I’d like to go over one of the most popular support levels: Rover. You’re a Rover-level patron if you contribute at least $5/month through Patreon. This reward level centers around our shared Discord community and advance notice of interviews.

Building a Community

One of the most amazing things that has come out of creating the WeMartians Podcast and subsequently building the Off-Nominal Podcast with my co-host Anthony is meeting and conversing with space enthusiasts all over the world. From emails to Twitter replies, Reddit comments & more, engaging with the space community is an awesome experience. But there’s never been a good forum for WeMartians listeners to congregate and share their passion.

Meanwhile, Anthony had started something with his podcast, Main Engine Cut Off. Using the integrated functionality of Discord and Patreon, he had created a chatroom for his listeners to meetup. When I asked him how it was going, he was proud to say that he had begun to see the inklings of what could be an incredible space for space. I wanted in on that action. But it didn’t make sense to compete. Anthony and I, by virtue of being podcast partners, shared a lot of listeners. It would be a bad experience for them to have two separate Discord servers to talk similar content.

A few conversations later we solved it. A shared space, branded under our partnership Off-Nominal, to host supporters of both Main Engine Cut Off and WeMartians. By bringing the communities together we simplified the experience. Plus, since the size of the community increased its value, we were stronger together.


What is Discord, anyway?

Discord is a software platform that was originally designed for Voice Over IP (VOIP) communication between gamers while playing multiplayer games. Think of it like Slack but for gaming. It has expanded to include all kinds of use-cases for communication, including Patreon communities. Users can communicate via chat in different text channels, sharing photos, links and more. Or, you can join voice channels to have vocal communication among a group. Discord can be run as an app on Windows, MacOS, Android or iOS, or directly in a browser. Here’s what you might see when you log in (I’ve edited this image to protect the identify of our supporters). It’s from a discussion about Space History and sharing our favourite photos and documentaries.

The Off-Nominal Discord is a private server that can only be accessed by supporting WeMartians (or Main Engine Cut Off) through Patreon at the $5 level. By creating an account with Discord and then connecting it to your Patreon account, you will automatically be added to the server seamlessly.

What Goes on in the Discord?

Because our community is global, there’s always something going on. As a user you set your own level of participation. Some supporters pop in once every few weeks to say hello and talk about something on their mind. Others find enjoyment from keeping the conversation going almost daily!

The topics we discuss are divided into broad areas, each with its own channel. This is helpful if you’re super interested in Space History but don’t care much about Space Policy. Simply mute the channels you don’t want to hear about! The channels we run today (available to all supporters at $5+ from either podcast) are:

  • #Announcements (for community announcements and events)
  • #General (for non-specific space related topics)
  • #Planetary (for Mars and other planetary science or exploration topics)
  • #Launch (for upcoming launches and launch vehicle technology)
  • #Policy (for politics, law, and strategy of space agencies and companies)
  • #History (for learning about the past of space)
  • #Random (for non-space related topics. This usually ends up being about listeners learning about other listeners and where they live)

We also have specific channels for those who support a specific podcast to discuss Patreon perks (more on that later). If you want to learn more about the channels, you might want to check out our helpful starter guide, which we give to new users who join.

Live Events

Sometimes, there’s an event happening, like a rocket launch or a Mars landing. These are great opportunities for the Discord community to get together and share the experience. Occasionally we’ll set up a voice channel to have a conversation about the event, or we might just stick to text based. These can be especially fun times to be a part of the group – the insights we get from each other amplify the experience!

We’ve also experimented with live recording sessions for Off-Nominal or other audio recording events (in fact, you can listen to one being published tomorrow!). We’re still ironing out these details, but it could mean you could hear one of the podcasts live as it is put together with the chance to offer questions or insights along the way. You could be a part of the show!

Patreon Perks

The private WeMartians channel has a special purpose. It is the one part of the server that is not shared with supporters of Main Engine Cut Off. There, listeners can discuss some of the perks that they get from being a Patreon supporter, from the Red Planet Review or Off the Cuff bonus content, to advance notice of guests (see below). It’s our private space just for Patreon Perks.

Advanced Notice of Interviews

The other key benefit of the Rover-level is advance notice of interviews. I try to plan my interviews as far as advance as possible to give myself flexibility in publishing and producing. I’m not always successful, but most of the time I can arrange for 3-7 days warning for Patreon supporters to know what I’m up to. Then, I ask for questions. I’ve gone back to Episode 36 with Farah Alibay, a payload systems engineer at NASA’s Jet Propulsion Laboratory and working on the InSight mission, and made the post public so you can see a real live example of what these notices look like.

For Rover-level supporters, this is a chance to be a part of the podcast. Have a specific question about the spacecraft our next guest is working on? Let me know and I’ll try to squeeze it in. Think I might miss an important fact for understanding a science paper on Martian rocks? Give me that heads up and I’ll do my best to get it answered. Want to know what it feels like to live in a habitat on a Mars analogue? Well, you get the idea.

If I read your question on the show, I’ll say your name so everyone knows who asked it. You will become not just a supporter, but a participant.

Combining Benefits

Remember, the notice of interviews is made that much better when combined with the Discord community. By popping in to the private WeMartians channel, you can talk with other supporters about upcoming interviews and plot your questions together!


The Rover-level is very popular because it combines two really key benefits. Having advance notice of interviews gives you the inside scoop on the next episode of the podcast and the chance to be a part of the interviews. The Off-Nominal Discord is a superb place to hang out, ask questions, share thoughts and learn something new. Together, they create wonderful benefit that not only benefits you but helps keep this podcast independent! That’s pretty cool.

February was a really great month! Not only did we travel to Florida to witness Falcon Heavy lift off for the first time, but we also achieved our third Patreon goal! We’ve now eclipsed $300 per month, meaning that I have the financial security to make at least one trip a year for the show. And that means we’re off to the races in building towards the WeMartians Travel Grant, our next goal of $450.

Thanks to all the Patrons who’ve pledged support already. We’re already 76% of the way to our goal of $450/month to kick off the WeMartians Travel Grant. This is so close! I would love to see this goal reached by the summer time so that we can get this project moving!

  • Red Planet Review (4 episodes) – Our new series continued through February with 4 more episodes. We talked about Mars 2020 progress, SpaceX’s Falcon Heavy rocket, lots of space analogues, new science, and spacecraft news. It’s for our Lander-level patrons ($3+/month), but the first episode was published for free if you’d like to try it out!
  • Bonus Content: Episode 37 (Falcon Heavy) – Prior to the Falcon Heavy launch, SpaceX held a press conference to address some of the questions. Anthony and I talked about what this meant from a restaurant in Titusville. It’s got a real authentic feel to it!
  • Discord Highlights – Over on the Off-Nominal Discord, our Rover-level ($5+) patrons continued to share in all kinds of great discussions. Membership has increased a lot lately which makes the community that much more rich. We’re recently created separate channels to help organize the discussion, and you can get a sneak peak by checking out this instruction sheet we give to new members. If you’d like to know more, check out on Monday – there’s a full explainer on what this benefit is! It’s a seriously cool place that I definitely recommend you check out.
  • Shop Discounts – Some of our members enjoyed their permanent discounts on the WeMartians Shop by contributing at the Station, Excursion and Base Levels! Perfect for picking up our new Extra-Nominal Shirt (celebrating Opportunity’s 5,000th sol) and our Falcon Heavy Sweater design!
