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!

Starship Flight 9 nears as SpaceX’s Starbase becomes a Texan City
SpaceX’s launch site is officially incorporated as Starbase, TX. Starship Flight 9 could launch on May 27, 2025.

SpaceX’s Starbase is officially incorporated as a city in Texas, aligning with preparations for Starship Flight 9. The newly formed city in Cameron County serves as the heart of SpaceX’s Starship program.
Starbase City spans 1.5 square miles, encompassing SpaceX’s launch facility and company-owned land. A near-unanimous vote by residents, who were mostly SpaceX employees, led to its incorporation. SpaceX’s Vice President of Test and Launch, Bobby Peden, was elected mayor of Starbase. The new Texas city also has two SpaceX employees as commissioners. All Starbase officials will serve two-year terms unless extended to four by voters.
As the new city takes shape, SpaceX is preparing for the Starship Flight 9 launch, which is tentatively scheduled for May 27, 2025, at 6:30 PM CDT from Starbase, Texas.
SpaceX secured Federal Aviation Administration (FAA) approval for up to 25 annual Starship and Super Heavy launches from the site. However, the FAA emphasized that “there are other licensing requirements still to be completed,” including policy, safety, and environmental reviews.
On May 15, the FAA noted SpaceX updated its launch license for Flight 9, but added: “SpaceX may not launch until the FAA either closes the Starship Flight 8 mishap investigation or makes a return to flight determination. The FAA is reviewing the mishap report SpaceX submitted on May 14.”
Proposed Texas legislation could empower Starbase officials to close local highways and restrict Boca Chica Beach access during launches. Cameron County Judge Eddie Trevino, Jr., opposes the Texas legislation, insisting beach access remain under county control. This tension highlights the balance between SpaceX’s ambitions and local interests.
Starbase’s incorporation strengthens SpaceX’s operational base as it gears up for Starship Flight 9, a critical step in its mission to revolutionize space travel. With growing infrastructure and regulatory hurdles in focus, Starbase is poised to become a cornerstone of SpaceX’s vision, blending community development with cutting-edge aerospace innovation.

United Airlines debuts Starlink Wi-Fi on Detroit flight
United’s first passenger flight with Starlink Wi-Fi just landed in Detroit. Mainline flights to follow by year-end.

United Airlines debuted Starlink Wi-Fi on its first passenger flight to Detroit, marking a milestone in in-flight connectivity with SpaceX’s satellite internet.
On Thursday, the morning flight from Chicago’s O’Hare International Airport introduced high-speed, gate-to-gate Starlink internet for United Airlines passengers. The Starlink-equipped United Embraer E-175, tail number UA5717, departed at 7:35 a.m. for Detroit Metropolitan Airport.
United announced the rollout on X, stating, “That lightning-fast Wi-Fi we told you about? It’s here. Our first customers just found out what it’s like to break the Wi-Fi barrier and stream, scroll, shop, and game just like at home with Starlink. And it’s FREE for MileagePlus members. Rolling out across our fleet now.”
The service leverages Starlink’s 7,000+ low Earth orbit (LEO) satellites to deliver broadband globally, including in remote areas. United is the only major U.S. airline currently offering Starlink. The airline plans to expand the service across its two-cabin regional fleet and introduce it on mainline flights by year-end.
Sean Cudahy from The Points Guy tested Starlink’s Wi-Fi pre-launch, praising its ease and reliability. “I ran a speed test, and it clocked the Wi-Fi at 217 Mbps of download speed, and 26.8 Mbps of upload speed,” Cudahy shared, noting its suitability for long flights.
Beyond aviation, SpaceX is pitching Starlink as a GPS alternative, emphasizing its potential for Positioning, Navigation, and Timing (PNT) services. This dual capability underscores Starlink’s versatility.
In a letter to the FCC, SpaceX wrote, “One opportunity stands out as a particularly ripe, low-hanging fruit: facilitating the rapid deployment of next-generation low-Earth orbit (‘LEO’) satellite constellations that can deliver PNT as a service alongside high-speed, low-latency broadband and ubiquitous mobile connectivity.”
As SpaceX expands Starlink’s applications, from aviation to navigation, United’s adoption signals a broader shift toward satellite-driven connectivity on long flights. With plans to equip more aircraft, United and Starlink are redefining in-flight internet, promising seamless digital access at 30,000 feet.

SpaceX touts Starlink as GPS alternative in FCC PNT push
SpaceX highlighted Starlink’s potential to deliver PNT services alongside its broadband offerings.

SpaceX is positioning its Starlink constellation as a viable GPS alternative. In a letter to the Federal Communications Commission (FCC), SpaceX stated that it could leverage Starlink satellites for next-generation Positioning, Navigation, and Timing (PNT) solutions.
GPS has been run through a single provider in the United States, the Defense Department. The FCC intends to use Positioning, Navigation, and Timing (PNT) solutions to complement GPS technologies. In its letter, SpaceX highlighted Starlink’s potential to deliver PNT services alongside its broadband offerings in its letter to the FCC.
“As the Commission identifies specific actions to contribute to the whole-of-government PNT system resilience effort, one opportunity stands out as a particularly ripe, low-hanging fruit: facilitating the rapid deployment of next-generation low-Earth orbit (‘LEO’) satellite constellations that can deliver PNT as a service alongside high-speed, low-latency broadband and ubiquitous mobile connectivity,” SpaceX wrote.
SpaceX also emphasized its ongoing work to integrate PNT into its cellular Starlink service, which is expected to be launched with T-Mobile in July. The private space provider also stated that Starlink satellites already operate independently of GPS. This lays the groundwork for resilient PNT delivery across authorized frequencies, SpaceX noted in its letter.
“SpaceX has also been actively working to integrate PNT solutions into its direct-to-device commercial service offerings. In so doing, SpaceX can advance the Commission’s goal in this proceeding to maintain American leadership in next-generation PNT services both here at home and in over 130 countries it serves around the world.
“SpaceX looks forward to playing an integral role in creating a more robust, resilient, and secure PNT ecosystem for Americans and people around the world,” SpaceX noted.
SpaceX also advocated for a “technology-neutral approach” to GPS alternatives in its letter, while critiquing EchoStar’s unused 2GHz spectrum for mobile satellite services. Meanwhile, Globalstar, Apple’s satellite provider, also pitched its services as a GPS complement, stating that its services “can function as either an alternative or a complement to GPS.”
“Notably, Globalstar’s satellites transmit outside of the L-band, which provides PNT users with added immunity from GPS jamming and spoofing. In addition, Globalstar’s satellite transmissions at 2.4GHz are stronger than GPS signals, bolstering resilience, performance, and reliability,” GlobalStar noted.
