SpaceX details plan to build Mars Base Alpha with reusable Starship rockets
For the first time, SpaceX has teamed up with researchers from NASA and several other US institutions to publicly discuss how it plans to use Starship to build Mars Base Alpha.
Save for a handful of comments spread around the periphery of SpaceX and CEO Elon Musk’s main focus, Starship itself, the company and its executives have almost never specifically discussed how the next-generation fully-reusable rocket will be used to create a permanent human presence on Mars. For the most part, that clear focus on near-term hurdles is hard to fault. Half a century of mostly theoretical analysis has made it abundantly clear that a permanent and sustainable extraterrestrial human outpost is impossible without a radical reduction in the cost of access to space. For decades, NASA has studied and studied and studied slight variations of a plan that would cost hundreds of billions of dollars to send a few astronauts to Mars for a few months at a time.
Put simply, without a revolution in space transport, even a temporary presence on Mars where inhabitants are mostly dependent on imported goods is infeasible unless Mars exploration is made a national or international priority on the order of tens of billions of dollars per year. Over the 80-90 years that spaceflight has been seriously pondered, dozens of groups and papers and studies and space agencies have imagined what that revolution might look like and SpaceX is not unique for proposing a solution to that longstanding problem. However, SpaceX is the first of that long list of contenders to propose a solution and both invest significant resources and put hammer to metal in an attempt to make that vision real.
Two years after SpaceX announced its intention to build that next-generation space transportation system, Musk revealed a radical design change and work on the first steel Starship prototypes began. Three years later, SpaceX has completed nine Starship test flights – four brief hops and five flights above 10 km (6 mi). In 2021 alone, SpaceX completed four of those high-altitude flight tests, recovered a high-altitude prototype intact for the first time, built the first orbital-class ship and booster prototypes, began testing that ship, and is nearly finished the first orbital Starship launch site from scratch. In April, SpaceX also secured a $2.9 billion NASA contract to build a human-rated Moon lander variant of Starship.
Put simply, SpaceX – and now NASA with it – has laid a sturdy foundation upon which Starship will almost certainly be realized. A great deal of work remains but SpaceX has more or less surmounted most of the major technical hurdles that towered over Starship/BFR/ITS just a few years ago. A wealth of Starship ground and flight tests have firmly demonstrated that the rocket’s structures, avionics, Raptor engines, exotic methods of descent and landing, and previously unflown fuel of choice are all ready for orbital flight. From then on, SpaceX will still need to prove out Starship’s massive, ceramic, non-ablative heat shield technology; mature orbital rocket refueling techniques and technologies; and finally operationalize all the above to make the rapid launch, reuse, and refueling of the largest rocket in history routine and mundane – something SpaceX has proven to be more than capable of with Dragon and Falcon.
How, then, will SpaceX proceed to the Red Planet?
Packing for Mars
With the help of coauthors from NASA Ames, SETI, and half a dozen prestigious US universities and institutes, SpaceX has begun to answer exactly that question in a 2021 whitepaper [PDF] submitted for the National Academies’ next Planetary Science and Astrobiology Decadal Survey. While that survey alone could influence NASA as the agency prepares to outline its next decade of space science and determine the ultimate destination of tens of billions of federal dollars, the consequences of which could be immense, SpaceX also used the paper to describe its plans for early missions to Mars in unprecedented detail.
As has always been the plan, SpaceX will begin the process of constructing sustainable cities on Mars with a few (relatively) simple steps. Likely as soon as the mid-2020s, SpaceX will begin launching uncrewed Starships to Mars to both verify the system’s maturity and readiness and “deliver significant quantities of cargo to the surface in advance of human arrival.” Likely leaning on a wide range of robotics, those early missions will help SpaceX characterize local resources, stage supplies, test technologies for long-duration Martian surface ops, and begin developing infrastructure – with a propellant plant likely the most pressing need. None of that is surprising. However, there’s more.
According to the authors, which include several current and former SpaceX engineers, “current SpaceX mission planning [tasks those early uncrewed Starships with delivering] equipment for increased power production, water extraction, LOX/methane production, pre-prepared landing pads, radiation shielding, dust control equipment, exterior shelters for humans and equipment, [and more – all hardware needed to support the first human base.]”
Further, confirming what’s been assumed to be the plan for years, “humans will likely live on [Starships] for the first few years until additional habitats are constructed” and “the first wave of uncrewed Starships can also be relocated and/or repurposed as needed to support the humans on the surface,” serving as “valuable assets for storage, habitation, [scientific laboratories], and a source of refined metal structures and resources.” The paper also states that “SpaceX is aggressively developing Starship to…conduct initial test flights to Mars…as soon as 2022 [or 2024]” and even raises the possibility of SpaceX launching the first Starship(s) to Mars before the rocket’s first lunar mission but then launching a separate lunar mission and landing a different Starship on the Moon while the Marsbound ship or ships are still in transit.
The whitepaper marks the first time that SpaceX (or those familiar with the company’s plans) has properly fleshed out the basics of its first crewed and uncrewed Starship missions to Mars and confirms a great deal of well-informed speculation. Namely, SpaceX appears to intend to pack even the very first Mars-bound ships with supplies. But even if they don’t bring much, the first Martian immigrants – launched in batches of “10-20 people” alongside “100+ metric tons” (~220,000+ lb) of cargo – will reuse all surviving Starships as pre-emplaced habitats, storage tanks, and raw material feedstock. Early cargo will focus on power, water, and propellant production, as well as shelters, radiation shielding, and the construction of prepared landing pads. Unsurprisngly, early residents will likely make the Starships that carry them to Mars their first homes on the surface of the Red Planet, taking advantage of an ~1100m³ (~39,000ft³) pressurized volume already outfitted to keep dozens of people alive and healthy in deep space for months at a time.

Elon Musk calls out $2 trillion SpaceX IPO valuation as ‘BS’
In a swift rebuke on X, Elon Musk dismissed reports claiming SpaceX had confidentially filed for an initial public offering targeting a valuation above $2 trillion, labeling the information as unreliable.
Elon Musk is quick to call out any false information regarding him or his companies on his social media platform, known as X.
A recent report that claimed SpaceX was aiming to go public with an IPO in the coming weeks at a massive valuation of $2 trillion was called out by Musk, who referred to it as “BS.”
In a swift rebuke on X, Elon Musk dismissed reports claiming SpaceX had confidentially filed for an initial public offering targeting a valuation above $2 trillion, labeling the information as unreliable.
The exchange highlights ongoing media speculation about the rocket company’s future and Musk’s frustration with what he views as inaccurate financial reporting. The report came from Bloomberg.
Don’t believe everything you read.
Bloomberg publishes bs.
— Elon Musk (@elonmusk) April 3, 2026
The controversy erupted on April 2, 2026, when influencer Mario Nawfal amplified claims from Bloomberg.
The outlet posted that SpaceX had boosted its IPO target valuation above $2 trillion, describing it as potentially one of the largest public offerings in history. Musk challenged the story.
It echoes past instances where Musk has corrected valuation rumors about his companies, emphasizing that speculation often outpaces reality.
Background context adds nuance.
Earlier reports indicated SpaceX had filed confidential IPO paperwork with the U.S. Securities and Exchange Commission, potentially positioning it for a record-breaking debut that could eclipse Saudi Aramco’s 2019 listing.
Initial estimates pegged a possible valuation north of $1.75 trillion, building on a post-merger figure around $1.25 trillion after SpaceX absorbed xAI. A subsequent Bloomberg update claimed advisers were floating figures above $2 trillion to investors, with the offering potentially raising up to $75 billion.
SpaceX remains a private powerhouse. Its achievements include thousands of Starlink satellites providing global broadband, routine Falcon 9 rocket reusability, and a mission to slash launch costs, along with ambitions for Starship to enable Mars colonization.
The company also benefits from government contracts with NASA and the Department of Defense. A public listing could democratize access for retail investors while subjecting SpaceX to greater scrutiny and quarterly reporting pressures.
Critics of the reports point to the confidential nature of filings, which limits verifiable details. Musk has previously downplayed inflated valuations, once calling an $800 billion figure for SpaceX “too high.”
Supporters argue that hype around mega-IPOs, especially amid the ongoing AI fervor, fuels premature narratives that distract from core technical milestones, such as full Starship reusability and Starlink constellation expansion.
The incident reflects broader tensions in tech finance. Anonymous sourcing in valuation stories can drive market chatter and betting activity, yet it risks misinformation.
Bloomberg defended its reporting through multiple articles citing “people familiar with the matter,” but Musk’s blunt dismissal resonated widely on X, with users piling on to question media reliability.
Whether SpaceX ultimately goes public remains uncertain. Musk has teased an IPO tied to Starlink maturity, but priorities center on engineering breakthroughs over Wall Street timelines. For now, the $2 trillion figure joins a list of rumored milestones that Musk insists should be taken with skepticism.

Elon Musk reveals date of SpaceX Starship v3’s maiden voyage
The announcement arrives after Flight 11 on October 13 of last year, which concluded a busy 2025 testing campaign. Since then, SpaceX has focused on ground testing, including cryoproofing of Ship 39 and preparations for Booster 19, the first V3 Super Heavy.
SpaceX CEO Elon Musk has revealed the timeline for the next Starship launch. It will be the first launch using SpaceX’s revamped design for Starship, as its v3 rocket will take its maiden voyage sooner than many might expect.
Musk announced on April 3 on X that the next Starship flight test, and the first flight of the upgraded v3 ship and booster, is 4 to 6 weeks away. The update signals the end of a nearly six-month hiatus since the program’s last launch.
Elon says the first V3 Starship launch will occur in 4-6 weeks
It will be the first Starship launch since Flight 11 on October 13, 2025 https://t.co/QnnYPTdbUu

The upcoming mission, designated as Starship’s 12 integrated flight test (IFT-12), marks a significant milestone. It will be the debut of the v3 configuration, featuring a taller Super Heavy Booster and Starship upper stage. The changes SpaceX has made with the v3 rocket and booster are an increased propellant capacity and the more powerful Raptor 3 engines.
Earlier predictions from Musk in March had pointed to an April timeframe, but the latest timeline now targets a launch window in early to mid-May 2026.
The V3 iteration represents a substantial evolution from previous Starship prototypes. Engineers have optimized the design for improved manufacturability, higher thrust, and greater efficiency. Raptor 3 engines deliver significantly more power while reducing weight and production costs compared to earlier variants.
With these enhancements, SpaceX aims to boost payload capacity toward 200 metric tons to low Earth orbit in a fully reusable configuration — a dramatic leap from the roughly 35-ton target of prior versions. Such capabilities are critical for ambitious goals, including NASA’s Artemis lunar missions and eventual crewed flights to Mars.
The announcement arrives after Flight 11 on October 13 of last year, which concluded a busy 2025 testing campaign. Since then, SpaceX has focused on ground testing, including cryoproofing of Ship 39 and preparations for Booster 19, the first V3 Super Heavy.
Recent activities have involved static fires, activation of the new Pad 2 at Starbase in Boca Chica, Texas, and integration of Raptor 3 engines.
A prior incident with an early V3 booster on the test stand in late 2025 contributed to the delay, necessitating additional assembly and qualification work.
Musk’s timeline updates have become a hallmark of the Starship program, often described with characteristic optimism.
SpaceX’s Starship V3 is almost ready and it will change space travel forever
While past targets have occasionally shifted by weeks, the rapid iteration pace remains impressive. However, don’t be surprised if this timeline shifts again, as Musk has been overly optimistic in the past with not only launches, but products under his other companies, too.
SpaceX continues to refine launch infrastructure, including new propellant loading systems and tower mechanisms designed to support higher cadence operations. A successful V3 flight could pave the way for more frequent tests, tower catches of both booster and ship, and progression toward operational reusability.
The v3 debut is viewed as a transition point for Starship, moving beyond experimental flights toward a system capable of supporting large-scale deployment of Starlink satellites, lunar landers, and interplanetary transport.
Success on IFT-12 would demonstrate not only the new hardware’s performance but also SpaceX’s ability to recover from setbacks and maintain momentum.
As the 4-to-6-week countdown begins, anticipation builds at Starbase. Teams are finalizing vehicle stacking, conducting final pre-flight checks, and preparing for regulatory approvals. The world will be watching to see if Starship V3 can deliver on its promise of transforming humanity’s access to space.

SpaceX to launch military missile tracking satellites through new Space Force contract
SpaceX wins a $178.5M Space Force contract to launch missile tracking satellites starting in 2027.
The U.S. Space Force awarded SpaceX a $178.5 million task order on April 1, 2026 to launch missile tracking satellites for the Space Development Agency. The contract, designated SDA-4, covers two Falcon 9 launches beginning in Q3 2027, one from Cape Canaveral Space Force Station in Florida and one from Vandenberg Space Force Base in California. The satellites, built by Sierra Space, are designed to bolster the nation’s ability to detect and track missile threats from orbit.
The award falls under the National Security Space Launch Phase 3 Lane 1 program, which Space Force uses to move payloads to orbit on faster timelines and at more competitive prices. “Our Lane 1 contract affords us the flexibility to deliver satellites for our customers, like SDA, more easily and faster than ever before to all the orbits our satellites need to reach,” said Col. Matt Flahive, SSC’s system program director for Launch Acquisition, in the official press release.
SpaceX is quietly becoming the U.S. Military’s only reliable rocket
The SDA-4 contract is the latest in a long string of national security wins for SpaceX. As Teslarati reported last month, the Space Force recently shifted a GPS III satellite launch from ULA’s Vulcan rocket to SpaceX’s Falcon 9 after a significant Vulcan booster anomaly grounded ULA’s military missions indefinitely. That move made it four consecutive GPS III satellites transferred to SpaceX after contracts were originally awarded to its competitor.
This didn’t come without a fight and dates back years. SpaceX originally had to sue the Air Force in 2014 for the right to compete for national security launches, at a time when United Launch Alliance held a near monopoly on the market. Since then, the company has steadily displaced ULA as the dominant provider, and last year the Space Force confirmed SpaceX would handle approximately 60 percent of all Phase 3 launches through 2032, worth close to $6 billion.
With missile defense satellites now part of its launch manifest alongside GPS, communications, and reconnaissance payloads, SpaceX is giving hungry investors something to chew on before its imminent IPO.
