How does SpaceX measure up to other Mars-destined challengers? [Countdown to Mars, Part 1]
SpaceX isn’t the only organization with eyes set on the skies of Mars. There are other dreamers with their own plans and technology. How does SpaceX measure up?
If it wasn’t entirely clear before, it is now with all the recent announcements from SpaceX: Elon Musk said “Mars”, and he really meant Mars. While Falcon 9 hits milestone after milestone, SpaceX inches closer and closer to “boots on the ground” in red, Martian regolith.
SpaceX isn’t the only organization with eyes set on Martian skies, however. There are other dreamers with their own plans and technology, NASA being a “given” of course. After all, if we’re going to Mars, it’s natural to expect the agency that sent humans to the moon to have something to say about sending humans to another planetary body.
Who all is planning on going to Mars?
To be clear, the Mars planners I’m referring to here are developing full missions for human transport, not just robotics. Further, I’m narrowing the criteria to only include those actively developing the technology rather than working on related scientific studies, developing artistic concepts, engineering helpful devices, and so forth.
In that light, it seems the field thus far consists of two other major players besides SpaceX.
NASA
Aptly named, NASA’s “Journey to Mars” program consists of developing all the capabilities needed to achieve what its designation implies. Their vision comprises the development of their next generation rocket, the Space Launch System, coupled with a crew capsule called Orion.
The Space Launch System has three primary components: One main core and two solid rocket boosters, most components being either derived or upgraded from space shuttle technology. The plan is to “evolve” the configurations through three “blocks”, the third of which will be capable of handling all of the payload needs for a mission to Mars.
The Orion capsule, nicknamed “Apollo on steroids”, is very similar to the capsules used in the Apollo programs, but with significant upgrades such as the heat shield that must handle higher reentry speeds. Further, it will house up to four astronauts (one more than Apollo) while supported by a service module, i.e., a connected structure that will provide resources such as power and oxygen. Overall, it’s about three feet wider than the Apollo capsules, an expansion which translates into a much roomier space square-footage wise.
Somewhere in NASA’s mix is an Asteroid Redirect Mission that involves capturing an asteroid, bringing it into orbit around the moon, and sending crews there to land and study it. Don’t see how that’s really related to Mars? Neither do I, but it’s included on all the “Journey to Mars” posters so it must be. I think I’ve heard people try and explain why the moon wouldn’t suffice for any Mars-related training as well, but I’m personally not convinced enough to really cite the argument. I’m not alone in that confusion, either.
Personally, I’d prefer the pure scientific study of an asteroid to be the justification for the mission, or maybe even “practice” for a future Armageddon event, but when everyone is drumming for Mars, I guess you do what you can. I’ve read that NASA attempted to market it as both of those, but the attempts weren’t successful.
Oh, wait. They changed “asteroid” to “large boulder on an asteroid”. I wonder why? Some of their pages are still citing the original mission… Perhaps it was always either/or?
Speaking of that poster, there’s a space habitat and Mars transfer craft listed, but no other details are provided. NASA’s political and budgetary constraints seem to be limiting any details about how they plan on getting to Mars (landing in particular) once SLS and Orion are flying. These types of restrictions are the reason NASA even has other contenders for the mission, although those same challengers are the ones pushing the journey into the public drumming in the first place.
Mars One
Mars One is a non-profit foundation which hopes to send astronauts they select and train through an in-house application process to Mars via technology they will pay to have built and launched using current service providers.
Founded by Dutch scientist-entrepreneurs Bas Lansdorp and Arno Wielders in 2011, Mars One is an unusual player in the Mars transport game. It is not an aerospace company, as all systems are designed and built by outsourced companies, and their planned sources of funding are private investment and the creation of a reality show documenting the astronauts’ mission from training through their first steps on Mars (although they’ve had some recent troubles with that). Mars One would also like you to purchase plenty of merchandise in the meantime to support their efforts and have even set up a “point” system to encourage this.
For their astronauts, the company solicited applications from would-be space travelers around the world via the Internet, received about two hundred thousand responses, and is now in the process of narrowing down their candidate field to a maximum of twenty-four hopefuls (six groups of four, specifically) that will train together for the next ten years before groups are shuttled off to Mars every two years.
Mars One also plans on having their entire human habitat set up by rovers prior to the first astronaut arrivals, meaning there will be several cargo missions to the surface in the lead-up years. Their first unmanned mission is planned for 2020 wherein some tech will be put to the test along with placing a communications satellite in orbit. Then, a rover and second communications satellite is planned for 2022, followed by cargo missions in 2024 to have the habitat fully operational by 2025 in advance of the first crew arrival in 2027.
Oh, by the way, their trip to Mars will be one-way. According to them, it’s a strategic choice, not a matter of insurance liability for guaranteeing return.
While all space-going organizations face criticism in one way or another, the criticism lodged at Mars One is fairly significant, some even labeling the mission as a scam. To be fair, the nature of their mission combined with the lack of government backing or a billionaire founder puts them in the position that demands fundraising to be a primary activity. Add to that an estimated mission cost of six billion dollars and skepticism quickly rises. Everything involved becomes subject to close analysis.
Their plans aren’t impossible, of course, just full of challenges without perceivable solutions. I don’t personally believe the mission is a scam, and I don’t doubt its long-term viability should the astronauts actually make it to Mars; I think they won’t be the only crews visiting the planet come the days when their intentions match their funding needs, therefore a “back up” plan is essentially built-in. However, I also see a ten-year mission plan that is placing a lot of faith in contract work that is supposed to produce what SpaceX is still working on fourteen years after-the-fact and with a much better financial portfolio.
Honorable Mention: “Mars Direct” by The Mars Society
Founded in 1998 by Dr. Robert Zubrin (and “others”), The Mars Society has made humans on Mars their business for a very long time. Since they are not an organization primarily developing & building technology to go to Mars, I have to classify them as “honorable mention”; however, their contributions to the effort should definitely be noted. Elon Musk certainly has.

“Mars Direct” is The Mars Society’s detailed plan for putting humans on Mars and, like Mars One, it focuses on building components using existing technology to achieve orbit and landing rather than depending on future developments. It advocates a “live off the land” approach that minimizes cargo needs.
The Mars Direct mission would comprise two phases. First, using a heavy lift launch vehicle, a fuel generation structure would be sent to the Martian surface to generate a Methane/Oxygen bipropellant for a return trip and to power equipment. Second, another fuel generation structure plus a crew and habitat would be sent and landed near the first structure. While in orbit, the effects of zero gravity would be mitigated by rotation of the crew vehicle via a tether connected to the spent upper stage of the transport rocket to act as an anchor. The crew missions would necessarily require a two-year length due to the orbital proximities of Earth and Mars combined with the six-month travel time each way.
Unlike Mars One, this plan has been developed with incredible detail and was published in 1991 by Dr. Zubrin, David A. Baker, and Owen Gwynne. The Mars Society also has annual conferences (this year’s will be the 19th one) which both flesh out the plan’s details and feature speakers across the aerospace spectrum discussing the various aspects. Dr. Zubrin’s book, The Case for Mars, fleshes out the plan in a more readable format, and there’s also plenty of good stuff on the Mars One website.
SpaceX’s Plan for Mars
The founding goal of SpaceX was, and still is, making humans a multiplanet species. Therefore, no incredibly detailed introduction or lengthy explanation is really needed for them when discussing companies interested in going to Mars (see: publicity). However, for the sake of being thorough (and for the sake of sake’s sake), let’s review the Musk brand for Mars.
Known for its Falcon rocket series (along with its famous founder), SpaceX isn’t hitching a ride to Mars as is Mars One, thereby avoiding the potential pitfall of being “all dressed up with nowhere to go”. They’re building their own ride: The Falcon Heavy.
Scheduled for a test launch this November, the Falcon Heavy will be the most powerful rocket in operation since the Saturn V was used for the Apollo moon program. With three cores powered by nine Merlin engines each, Falcon Heavy will be able to haul around 120,000 pounds to low earth orbit (LEO), 50,000 pounds to geostationary transfer orbit (GTO), and 30,000 pounds of payload to Mars. Just for fun, SpaceX’s website also cites a 6,400 pound payload capacity for trips to Pluto.
SpaceX is also developing their own crew capsule, the Dragon (“Red Dragon” when on its way to Mars), which will include a propulsive landing system (i.e., it can hover) via its eight SuperDraco engines. The landing system also doubles as an emergency escape system in the event that there’s a problem during launch, and while space traveling, Dragon will be supported by a “trunk” (essentially with the same function as Orion’s service module) to support missions as needed.
Now, pardon my excitement, but these things are really cool. The SuperDraco engines are doubled up and self-contained, meaning that the lander can lose up to half its engines and still land safely, and if anything goes wrong with one engine, it’s isolated to not impact the others. The engines are also 3D-printed out of Inconel, a high performance nickel-based super alloy.
Bonus level! SpaceX’s long-terms plans don’t just include short(ish) jaunts to Mars and back, although, unlike Mars One, there will be an option to return to Earth via regular cargo missions. There also may be an option with their up and coming Mars Colonial Transport vehicle.
The Mars Colonial Transporter is, at the moment, a mysterious development SpaceX is working on to achieve its goal of large-scale Martian colonization. There’s plenty of speculation about the details, but officially, even the size is being kept secret for now. Elon will only reveal it to be “So big.” A few details were shared (or speculations confirmed) during a Reddit “Ask Me Anything “ (AMA) session this past January such as:
- The second stage could be reusable
- The architecture will be completely different from the Falcon/Dragon system
- The goal payload capacity is 100 metric tons
- There is a family of methane-based engines called “Raptor” being developed by SpaceX for travel to and exploration of Mars.*
*Note: This detail wasn’t particularly new to the AMA, but there aren’t many original sources where Elon or a SpaceX executive has spoken directly about it, thus I’ve included it.
Overall, it certainly seems like SpaceX is charging ahead compared to the others that are aimed for Mars, but it’s not because of their publicity wins. Their steady march via the piece by piece development of the required technology combined with the customer-driven financial viability of the company as a rocket launch provider are key to the believably that they will actually make Mars “happen”.
Coming Up on Countdown to Mars…
SpaceX’s colonial “grand plan” reveal is what I’m counting down to with this “Countdown to Mars” article series. Scheduled for September 26th – 30th of this year, Elon Musk has stated that he will be announcing detailed plans for their Mars Colonial Transporter at the International Astronautical Conference in Guadalajara, Mexico. It’s supposed to be so awesome, even Elon can hardly contain himself. To say that I’m incredibly excited as well would be a huge understatement. So I won’t. I’ll just keep writing about things related to it!
Coming up on “Countdown to Mars”…
How do these companies plan on solving some of the biggest challenges for achieving a successful mission to Mars? Then, if we are talking about permanent settlements on Mars, what will the human power structure look like? Or in other words, what kind of government will the first human Martians have?
Stay tuned!

SpaceX weighs Nasdaq listing as company explores early index entry: report
The company is reportedly seeking early inclusion in the Nasdaq-100 index.
Elon Musk’s SpaceX is reportedly leaning toward listing its shares on the Nasdaq for a potential initial public offering (IPO) that could become the largest in history.
As per a recent report, the company is reportedly seeking early inclusion in the Nasdaq-100 index. The update was reported by Reuters, citing people familiar with the matter.
According to the publication, SpaceX is considering Nasdaq as the venue for its eventual IPO, though the New York Stock Exchange is also competing for the listing. Neither exchange has reportedly been informed of a final decision.
Reuters has previously reported that SpaceX could pursue an IPO as early as June, though the company’s plans could still change.
One of the publication’s sources also suggested that SpaceX is targeting a valuation of about $1.75 trillion for its IPO. At that level, the company would rank among the largest publicly traded firms in the United States by market capitalization.
Nasdaq has proposed a rule change that could accelerate the inclusion of newly listed megacap companies into the Nasdaq-100 index.
Under the proposed “Fast Entry” rule, a newly listed company could qualify for the index in less than a month if its market capitalization ranks among the top 40 companies already included in the Nasdaq-100.
If SpaceX is successful in achieving its target valuation of $1.75 trillion, it would become the sixth-largest company by market value in the United States, at least based on recent share prices.
Newly listed companies typically have to wait up to a year before becoming eligible for major indexes such as the Nasdaq-100 or S&P 500.
Inclusion in a major index can significantly broaden a company’s shareholder base because many institutional investors purchase shares through index-tracking funds.
According to Reuters, Nasdaq’s proposed fast-track rule is partly intended to attract highly valued private companies such as SpaceX, OpenAI, and Anthropic to list on the exchange.

Starbase after dark: Musk’s latest photo captures a Spaceport on the brink of history
SpaceX’s Starbase city in Boca Chica, Texas is rapidly transforming the southern tip of the Lone Star State into one of the most ambitious launch complexes in history.
A striking nighttime photograph of SpaceX’s Starbase facility in Boca Chica, Texas, shared recently by Elon Musk on X, offers a dramatic glimpse of an operation that is rapidly transforming the southern tip of the Lone Star State into one of the most ambitious launch complexes in history.
The most immediately visible change in the photo is the presence of two fully erected Starship launch towers dominating the coastal skyline. The second orbital launch pad, known as Pad B, now features its fully erected tower, OLIT-3, which stands approximately 474 feet tall and incorporates an integrated water-cooled flame trench designed to minimize damage and reduce turnaround time between launches. The dual-tower silhouette against the night sky signals a decisive shift from experimental testing facility to high-cadence launch operations.

Back at Starbase, Pad 2 is approaching hardware completion, with upgraded chopstick arms, a new chilldown vent system, and all 20 hold-down arms now fitted with protective doors to shield them from the intense exhaust of up to 33 Raptor 3 engines, according to a deeper dive by NASASpaceFlight.
SpaceX has also received approval to nearly double the footprint of the Starbase launch site, with groundwork already underway to add LNG liquefaction plants, expanded propellant storage, and additional ground support infrastructure.
The photo also carries a milestone civic dimension. Starbase officially became a Texas city in May 2025 after a community vote, with SpaceX employees elected as mayor and commissioners of the newly incorporated municipality. That legal status streamlines launch approvals and gives SpaceX direct control over local infrastructure decisions.
The FAA has approved an increase in launches from Starbase in Texas from five to twenty-five per year, clearing the runway for the kind of flight frequency needed to fulfill Starship’s ultimate mission of ferrying cargo and crew to the Moon, servicing the Department of Defense, deploying next-generation Starlink satellites, and eventually establishing Elon Musk’s long sought after goal of a self-sustaining human presence on Mars.
Seen from above in the dark, Starbase looks less like a test site and more like a spaceport.

Elon Musk shares updated Starship V3 maiden launch target date
The comment was posted on Musk’s official account on social media platform X.
SpaceX CEO Elon Musk shared a brief Starship V3 update in a post on social media platform X, stating the next launch attempt of the spacecraft could take place in about four weeks.
The comment was posted on Musk’s official account on social media platform X.
Musk’s update suggests that Starship Flight 12 could target a launch around early April, though the schedule will depend on several remaining milestones at SpaceX’s Starbase launch facility in Texas.
Among the key steps is testing and certification of the site’s new launch tower, launch mount, and tank farm systems. These upgrades will support the next generation of Starship vehicles.
Booster 19 is expected to roll to the launch site and be placed on the launch mount before returning to the production facility to receive its 33 Raptor engines. The booster would then return for a static fire test, which could mark the first time a Super Heavy booster equipped with Raptor V3 engines is fired on the pad.
Ship 39 is expected to undergo a similar preparation process. The vehicle will likely return to the production site to receive its six engines before heading to Massey’s test site for static fire testing.
Once both stages are prepared, the booster and ship will roll out to the launch site for the first full stack of a V3 Super Heavy and V3 Starship. A full wet dress rehearsal is expected to follow before any launch attempt.
Elon Musk has previously shared how SpaceX plans to eventually recover Starship’s upper stage using the launch tower’s robotic arms. Musk noted that the company will only attempt to catch the Starship spacecraft after two successful soft landings in the ocean. The approach is intended to reduce risk before attempting a recovery over land.
“Should note that SpaceX will only try to catch the ship with the tower after two perfect soft landings in the ocean. The risk of the ship breaking up over land needs to be very low,” Musk wrote in a post on X.
Such a milestone would represent a major step toward the full reuse of the Starship system, which remains a central goal for SpaceX’s long-term launch strategy.
