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!

The Tesla and SpaceX merger everyone is talking about is quietly building
Tesla and SpaceX may be closer to merging than Wall Street or either company is admitting.
Elon Musk has reportedly discussed merging Tesla and SpaceX with people close to him, according to CNBC, which cited sources familiar with the conversation. Tesla employees have long expected such a transaction and the topic is openly discussed internally, according to internal sources. With SpaceX is days away from kicking off its Wall Street roadshow for what could be the largest IPO in market history, this would be the first time the company will have public market currency to execute a stock-for-stock deal with Tesla.
The financial logic for a merger would make sense. A combined SpaceX and Tesla would create a conglomerate spanning rockets, satellites, electric vehicles, AI infrastructure, and energy storage valued at roughly $3.35 trillion to $3.6 trillion based on SpaceX’s IPO target range and Tesla’s current market capitalization. The two companies are already more intertwined than most people realize. SpaceX bought $697 million worth of Tesla Megapack systems for xAI data centers and $131 million worth of Cybertrucks. Tesla invested $2 billion in xAI, which subsequently merged with SpaceX. Past transactions also include Tesla selling solar equipment and parts to SpaceX, and SpaceX helping with Cybertruck materials.
Will Tesla join the fold? Predicting a triple merger with SpaceX and xAI
Musk himself signaled where this was heading in November 2025 when he posted on X, “My companies are, surprisingly in some ways, trending towards convergence.” Tesla and SpaceX announced a joint semiconductor fabrication facility in Austin called Terafab on the Gigafactory Texas campus, covering two advanced chip factories, with one serving Tesla’s AI needs for vehicles and Optimus robots, the other targeting space-based data centers under SpaceX’s infrastructure vision.
Wedbush analyst Dan Ives places the probability of a merger at 80% to 90% with a target completion in the first half of 2027. The mechanics of a deal became possible the moment SpaceX filed its S-1. Legal experts said a merger likely would not spark antitrust issues but would raise concerns among shareholders in each company, with questions around which company would be the parent, how a stock swap would take place, and who determines the appropriate price. Musk holds about 20% of Tesla’s equity but controls 85.1% of SpaceX’s voting power through a super-voting share class, meaning he would largely be negotiating the terms with himself.
Not everyone is convinced the timing is imminent. Traders on Kalshi place only 33% odds that a merger will happen before May 2027. The more immediate concern for Tesla shareholders is whether the SpaceX IPO pulls capital and Musk’s attention away from Tesla before any merger consolidates the upside for both.
What is clear is that the structural groundwork is already being laid. The Terafab announcement, the xAI merger, the shared supply chain, the cross-company balance sheet transactions, and now the IPO all point in the same direction. Whether the merger follows in 2027 or later, the two companies are already operating more like divisions of a single entity than independent competitors.

NASA’s first human outpost on the Moon starts now – SpaceX on deck
NASA named the rovers, landers, and vendors that will build America’s first Moon Base.
NASA has laid out its most detailed Moon Base plan to date, describing a permanent outpost near the Moon’s south pole that the agency intends to build over the coming decade as a direct stepping stone to Mars. “The Moon Base will be America’s and humanity’s first outpost on another celestial world,” NASA Administrator Jared Isaacman said, adding that every mission crewed and uncrewed “will be a learning opportunity as we return to the lunar surface, build the infrastructure to stay, and master the skills required to live and operate in one of the most demanding and dangerous environments imaginable.”
The plan is structured in three phases involving both uncrewed and crewed missions to deliver equipment, vehicles, and infrastructure to the surface, with the first three moon base missions targeted to launch before the end of 2026.
Moon Base I, targeting fall 2026, will use Blue Origin’s Blue Moon Mark 1 lander to deliver scientific instruments to the Shackleton Connecting Ridge, the same region where Artemis astronauts will land. Moon Base II will send Astrobotic’s Griffin lander carrying more than 1,100 pounds of cargo including Astrolab’s FLIP rover to begin developing mobility systems on the surface. Moon Base III will carry the Lunar Vertex science mission on Intuitive Machines’ Nova-C Trinity lander to study lunar swirls near the south pole, with ESA and Korean science payloads aboard.
On the rover side, NASA awarded Astrolab $219 million and Lunar Outpost $220 million to build the first phase of Lunar Terrain Vehicles, with both rovers targeted for deployment to the lunar surface by 2028. Astrolab’s crewed rover weighs roughly 2,000 pounds and can reach over 6 mph. Lunar Outpost’s Pegasus rover can operate autonomously or via remote control at over 9 mph. Blue Origin separately received $188 million with an option worth $280.4 million to deliver cargo landers for rover transport.
NASA also confirmed that MoonFall, a mission deploying four survey drones to scout Artemis landing sites, has selected Firefly Aerospace to build the transport spacecraft, with a 2028 launch target.
SpaceX sits at the center of that commercial layer. SpaceX holds the NASA Human Landing System contract for the Starship-derived lander that will put astronauts on the surface under Artemis IV, currently targeting 2028. Before that can happen, SpaceX must demonstrate in-orbit propellant transfer at scale, a process requiring multiple Starship tanker launches to fuel a single mission. Water ice at the lunar south pole is central to the base’s long-term viability, as it can be converted into drinking water, breathable oxygen, and rocket fuel, directly reducing dependence on Earth resupply. That resource loop becomes far more practical if Starship can land and be refueled on or near the Moon itself.
Elon Musk has publicly stated that Starship V3, which recently completed its first flight, should be capable enough for initial Mars missions. The Moon Base plan announced Tuesday is the infrastructure layer that connects everything between those two ambitions, and SpaceX is the only American company currently contracted to build the rocket that gets humans to either destination.
SpaceX’s Starlink product has just gotten its latest airline adoptee, and the move marks the successful partnership of three of the “Big Four” U.S. airlines.
American Airlines announced on Tuesday that it would utilize Starlink in more than 500 narrowbody aircraft beginning in the first quarter of 2027. These include the Airbus aircraft in its fleet, including the new A321XLR and A321neo.
With the new partnership with American Airlines, Starlink is now present on three of the largest airlines in the country: American, United, and Southwest.
Starlink gets its latest airline adoptee for stable and reliable internet access
Starlink’s VP of Enterprise Sales, Jason Fritch, said:
“We are proud to bring Starlink on board American Airlines, delivering fast and reliable internet to passengers and crew. Whether traveling for leisure or business, Starlink enables a fully connected experience gate to gate, making every flight smoother and more enjoyable.”
Additionally, American Airlines Chief Customer Officer, Heather Garboden, said:
“As a premium global airline, we are continuously seeking out world-class partners like Starlink to deliver what our customers need and want. The addition of Starlink solidifies American as a leading airline in keeping passengers connected in flight.”
Starlink has been on a tear over the past year, as it has continued to be adopted by a wide variety of airlines as a more consistent and reliable way to provide WiFi to its passengers. It has already gained a great reputation among residential users, but its biggest commercial application appears to be how it is being used in the air.

The only airline of the Big Four not to adopt Starlink thus far is Delta, which chose to opt for the alternative, which is Amazon Leo. CEO Ed Bastian said to Bloomberg that Delta chose Amazon’s product over Starlink’s because “the opportunities, in terms of the improved bandwidth with a much lower price point than what we’ve ever seen from Starlink, will make a big difference.”
Delta will not start installing Amazon Leo until 2028.
“Of course, we expect Starlink will be warning people that we’re going to go with an inferior product,” Bastian said. “But I’m not too worried about partnering with Amazon.”
