Finding Mars: A #NASASocial Experience

Finding our way to Mars is going to take an unprecedented amount of resolve. We’ll need the best people, the wisest use of equipment, and the most thought through of plans.

When I participated in the #NASAMarsDay NASA Social August 17 and 18, I got an in-depth look at the people, the equipment, and the plans involved in the journey to Mars. Although I had been a believer already in the idea that we will have humans on Mars in the 2030s, I am a better informed and more inspired believer now.

It’s Technical

Although I have been to two previous NASA Socials (documented here and here), the only attention I had given specific to Mars was taking this picture as an afterthought during one of our tours:

Space Exploration

After a day at Michoud Assembly Facility and Stennis Space Center, I have a much better understanding of the technical feats that have to occur in order for us to make it to Mars.

Getting to Mars happens in stages. Currently, primary transportation capabilities have been established via the Space Launch System (SLS) and Orion, the crew transportation vehicle. Low earth orbit missions involving the International Space Station are conducting tests of deep space hardware and operations.

The phase following low earth orbit missions, slated for the 2020s, will be proving ground missions. These initial missions near the moon will demonstrate important space systems as well as early elements of Mars transportation vehicles. Two components needed for Proving Ground missions, the transit habitat and the deep space tug, are in the early development stage.

In the early 2030s, NASA plans missions to the Mars vicinity using the vehicles and systems validated in cislunar space. These missions will prove capabilities for transit to Mars.

Lastly, in the mid to late 2030s, humans will be capable of landing on and ascending from Mars, and of exploring on that planet. Two building blocks of this phase, the Mars Lander/Heat Shield and the Mars Ascent Vehicle, are still in the conceptual phase.

Note: Some of the above information relied heavily on Boeing’s A Path to Mars. Thanks, Boeing! There is lots of indepth information from NASA here as well.

I now can speak a tiny bit more knowledgeably about friction stir welding, a solid-state joining process that produces faster, higher quality welds than traditional fusion welding by using an accurate, repeatable, and environmentally friendly process. (More info here and here.)

Short layperson’s explanation: because friction stir welding doesn’t melt the metal like traditional welding does, it doesn’t compromise it.

Additive manufacturing is essential. Niki Werkheiser said it best in this podcast: “…additive manufacturing is actually the kind of formal term for 3D printing. Traditional manufacturing is subtractive. You have a material and you take away from it. Additive is any process where you actually build the part that you’re trying to create, layer by layer, so it’s additive instead of subtractive.”

Short layperson’s explanation: there’s no Lowe’s or Home Depot on Mars. When you need a part you don’t have, you can’t go down the street to buy it. You have to know how to make it yourself out of components you already have. 

Cleanliness matters. When we visited the RS-25 assembly area, we were reminded of the importance of keeping things clean, clean, clean. Even the oil from a quick touch of a finger can compromise the manufacturing process. Everywhere you go, “FOD” reminders are posted.

Note the “FOD Awareness Area” barrier around the service module conical adaptor.

FOD is foreign object debris/foreign object damage and it is apparently the devil’s equivalent in the space construction arena. (And those of you who know me best know that yes, I do have a post floating around in my mind that parallels space FOD with life FOD and how we can let the smallest piece of trash mess up a perfectly good plan … that post will have to wait!) This post is older, but it’s an example of FOD analysis and follow-up planning.

Short layperson’s explanation: when you are in a facility that constructs launch vehicles, engines, crew modules, or any other component of space travel, don’t be careless. Don’t touch anything without permission and for heaven’s sake don’t carelessly drop your gum wrapper or last week’s crumpled up grocery list. Small debris can do huge damage.

It’s Technical, But Without People the Technology Means Nothing

Between the formal presentations and the less formal exhibits, we talked to MANY people. Formal presenters included Todd May, Director of NASA Marshall Space Flight Center; Astronaut Rick Mastracchio, Bill Hill, Deputy Associate Administrator for the Exploration Systems Development at NASA Headquarters, Richard Davis, Assistant Director for Science and Exploration, Planetary Science Division at NASA Headquarters; John Vickers, Principal Technologist for the Space Technology Mission Directorate at NASA Marshall Space Flight Center; John Honeycutt, SLS Program Manager; Bobby Watkins, Director of Michoud Assembly Facility; Lara Kearney, Orion Crew and Service Module Manager; and Katie Boggs, Manager for Systems and Technology Demonstration at NASA Headquarters.

Each speaker named above shared a glimpse into their specialty. For example, Bill Hill explained the difficulty of getting through Mars’s atmosphere. Rick Davis elaborated on the need for a semi-permanent base. Katie Boggs, below, explained why we have to become independent of earth in order to be able to exist on Mars.

When we visited the exhibit area, I learned about many additional aspects of the Journey to Mars. The Dream Chaser Cargo System is a commercial reusable spacecraft designed to provide transportation services to low-Earth orbit (LEO) destinations.

I enjoyed the opportunities to, literally, “ask a real rocket scientist” and “ask a real space architect.” I asked; I learned.

Space Exploration

One exhibit had to do with one of my favorite NASA projects, one I have had the privilege to hear about at each NASA Social, and one even a generic layperson like me can understand: the VEGGIE project, which is figuring out how to grow food in space!

Space Exploration

This is only a FRACTION of the exhibits we saw, the speakers we heard, and the technology to which we had access. As Bill Hill said, “We’re going to need everybody.” What I saw on this day was a great cross-section of “everybody.”

The Technology + The People Made For a Successful RS-25 Engine Test-Fire

The grand finale of our day was a test-fire of the RS-25 engine. After being transported to Stennis Space Center, we were given a tour of the Rocketjet Aerodyne Facility (there are no pictures for security reasons). We learned about how heritage Space Shuttle engines are being upgraded in order to power the SLS on its successively more complex missions related to the Mars journey.

Around 5 pm CST, we were in place at the viewing area, earplugs protecting our ears. As the test commenced, we were about 1500 feet from the plume of the test fire.

Here’s my image of the test fire:

But honestly, some things (such as capturing test fire images) are best left to professionals. Therefore, here is NASA’s recording:

I don’t know if the picture or the video really convey the power and awe, but it was powerful and awesome! At our “goodbye moment” in the parking lot of Michoud Assembly Facility, John Yembrick, NASA Social Media Manager, reminded us “when we go to Mars someday, you will have seen these engines in person. Imagine four of them and two boosters getting us to Mars. You can’t replicate that in pictures or on tv.” (This is a bit of a paraphrase; I don’t remember his exact words but the point was: you’re so lucky to have been here and seen this. I concur!)

History Matters

I have probably driven past the exits to Stennis Space Center 15-20 times in my lifetime as I went to Baton Rouge and New Orleans on various trips. Never did I realize what a behemoth of a complex existed south of me. As our informative guide Virgil explained, Stennis is a “federal city.” The towns and people that once existed there, which were displaced so that Stennis could be built, deserve our respect and gratitude.

Other sacrifices, big and small, are being made now and have been made over the history of the space program. We all know about the lives that have been lost. Smaller incremental sacrifices occur along the way: years of study, patience with failed experiments, the dogged pursuit of Federal funding (and the constant quest to reduce expenses).

In Closing

Before I talk about dollars and cents, as a mom of a daughter it is critical to emphasize that one of my huge motivators for being a social media ambassador for NASA is the fact that I want the young girls in my life (and heck, the “older” girls and women who may be considering career changes) to be comfortable with and excited not just by STEM, but by  STEAM: Science, Technology, Engineering, Arts, and Math. The first person I heard talk about STEAM was NASA Deputy Administrator Dava Newman and I have been intrigued ever since.

Count me in as one citizen who feels confident in NASA’s efforts and I fully support its continued Federal funding. Every dollar spent on NASA adds $10 to our US Economy.

Right before we went to observe the RS-25 test fire, we saw a brief presentation by Howard Conyers, principal investigator or the HiDyRS-X project which is refining a high-speed video camera system to provide high dynamic range capabilities with one camera. When Dr. Conyers presented a recording of a test fire from the naked eye and a test fire from the HiDyRS-X camera, it was stunning to discover how much detail is missed by the  naked eye, especially once the images are slowed down in infinitesimally small increments. I recall seeing  how there was shimmy in the nozzle once the advanced technology was used.

The presentation of the HiDyRS-X camera was a perfect example of a principle that will get us to Mars: technology + people + tenacity to solve problems and find answers.

Let’s pull this blog back up in 2040 and see how it all went. You know what? Maybe an astronaut on Mars will send me a screenshot of this very blog on their screen and prove that we did indeed make it. Now that’s the kind of 2040 email I would like to find.

This post is inspired by the following Mama’s Losin’ It prompt: Write a post where the first and last sentences contain any form of the word “find.”

    • It was interesting! It’s simply astounding how many small steps (that lead to big accomplishments) are involved in a goal like this.

  1. I love how much humans are learning about the world…but there is no amount of money you could pay me to get me to fly to Mars! I like my feet planted firmly on planet Earth. 🙂

    • I love it too — and at the risk of sounding like I’ve wholesale drunk the NASA koolaid — the technological advances made that will get us to Mars and other areas of space end up making HUGE differences here on Earth. // I don’t think I would have the guts to go either, honestly (and unfortunately). The amount of training/rigor/intensity these astronauts go through boggles my mind. I have tremendous respect for them (and I’m very psyched that women are well represented in the newer astronaut classes).
