SpaceX could begin testing its Mars rocket in Texas by late 2018, early 2019
On the heels of a successful wet dress rehearsal for Falcon Heavy, SpaceX’s President and COO Gwynne Shotwell spoke briefly about SpaceX for an aerospace conference located at Texas’ Academy of Medicine, Engineering & Science. Ars Technica’s senior spaceflight editor Eric Berger was in attendance and provided a rough outline of live tweets during the first group of presentations.
While the phrasing cannot provide absolute confirmation, Berger summarized a statement by Shotwell suggesting that SpaceX’s Boca Chica, Texas launch site, currently in the early stages of construction, could be ready to host “vehicle tests” as soon as late 2018, early 2019. At this point in time, based on comments from Shotwell and CEO Elon Musk, it can be reasonably assumed that SpaceX’s Texas launch facilities will be dedicated mainly to the company’s interplanetary colonization efforts, and will probably be tailored to support the testing and eventual launches of BFR/BFS.
Some news from Shotwell: Brownsville launch site ready for vehicle tests in late 2018, early 2019. Move to launch site after that.

After nine months of earnest construction and rehabilitation, SpaceX’s LC-40 pad was recently reactivated and has since supported two launches without any major hitches. At the same time, LC-39A in flux in order to support launches of SpaceX’s new Falcon Heavy rocket, the size of which required some concomitant upgrades to multiple ground systems. With both of those major tasks now effectively complete, SpaceX’s pad construction team is free to either refocus their efforts towards Boca Chica. Over the past several months, Boca Chica has seen a gradual but consistent level of development, mainly by way of unaffiliated SpaceX contractors. These changes have been dutifully tracked over the last several years on NASASpaceflight.com forums by a handful of friendly local residents interested in the changes coming to Boca Chica and Brownsville, Texas, a nearby town.

Most significantly, the last several months have seen three major developments. First and most prominently, a permanent facility called STARGATE externally appears complete and its two large radio communication dishes have been installed nearby. The STARGATE facility is a public-private partnership between the University of Texas at Brownsville (now part of University of Texas Rio Grande Valley) and SpaceX, with the academic components focusing on research that SpaceX undoubtedly has interest in: improved orbital spacecraft tracking and communications. Operationally, SpaceX will use the facilities to communicate with and operate its Crew Dragon spacecraft during launches, set to begin with an uncrewed demonstration mission as early as August 2018.
Second, an absolutely massive trolley crane appeared on SpaceX’s land and was eventually housed in an apparently purpose-built shed. The crane dwarfs anything currently used at SpaceX’s launch facilities and is almost certainly a custom-ordered piece of equipment, and thus would be both expensive and explicitly purposeful. What that purpose might be is currently unknown, but it is entirely plausible that the crane is intended to support initial testing (or even limited manufacturing) of SpaceX’s first BFS prototype rockets. This speculation has now been strengthened by Shotwell’s January 11 2018 comment on potential “vehicle tests” occurring at the site within a year or so, and also meshes with a presentation she gave in October 2017 at MIT. It also fits with Elon Musk’s 2017 IAC comments that BFR construction tooling and facilities were respectively already ordered and under construction.

Third and last, the aforementioned SpaceX-following locals observed the early stages of a solar power install beginning on some of SpaceX’s Boca Chica land in late 2017, and also noted that at least some of its contractors were part of Tesla Solar. Plans and permits for solar power were acknowledged as far back as 2014, although at that point the contractor was Solar City (now a part of Tesla). A handful of months later, NASASpaceflight user and all-around awesome guy Nomadd has installed a webcam on a tall pole with a wonderful view of both the solar installation (now nearly completed) and STARGATE. The acre of solar panels can be expected to produce as much as half a megawatt (MW) at peak sun, likely more than enough to offset a considerable amount of the facilities’ electricity usage even after it begins to be see serious use.

Originally announced as an additional Falcon launch facility in 2014, Boca Chica has remained relatively dormant over the last three years, and it is truly exciting to see activity ramping up. There are admittedly significant barriers that will prevent SpaceX from effortlessly repurposing its Boca Chica pad for BFR, a much larger rocket. If SpaceX intends to do that, they will almost certainly need to pass a significantly updated FAA environmental impact review and account for any remediations that might be required. Still, that is a small ask for for Brownsville’s local government and Texas as a whole, both of which have clearly enjoyed and begun to benefit from SpaceX’s presence in the otherwise unknown area. SpaceX is unlikely to give up on Boca Chica in the near term, so long as Ms. Shotwell maintains her belief that it is effectively the perfect location for BFR launches.
Overall, Shotwell’s comments over the last several months and today in particular are increasingly encouraging, and things are likely to only speed up as 2018 progresses, allowing SpaceX to focus more and more of its expertise on BFR, BFS, and its South Texas testing and launch facilities.
Full disclosure: As Shotwell did not specify which vehicle or vehicles could be expected to begin testing in 2018/2019, it is possible that Falcon 9, not BFR, was the statement’s target. This article should be taken with a grain of salt, as it is educated speculation based upon public information from SpaceX executives and Texas contractors. Teslarati reached out to SpaceX for additional information, but the company was unable to comment further on Shotwell’s presentation at the moment.

Elon Musk has declared that SpaceX has effectively solved one of Starship’s most persistent engineering challenges: the reliability of its heat shield tiles.
During the company’s first-ever Earnings Call, the SpaceX CEO stated:
“I don’t want to jinx it or anything, but I think I would call the heat shield problem solved at this point. All indications from data and visual inspection is we have solved it. That doesn’t mean we won’t make improvements, but we do not see any technical obstacles to achieving rapid reusability at this point.”
Starship’s heat shield consists of roughly 18,000 hexagonal ceramic tiles covering the windward side of the upper stage. These tiles form the thermal protection system that shields the vehicle’s stainless-steel structure from the extreme heat of atmospheric reentry.
Elon says he believes the heat shield problem with Starship is currently solved.

During descent, atmospheric friction generates temperatures exceeding several thousand degrees Celsius and creates plasma flows capable of melting unprotected metal. The tiles absorb, radiate, and insulate against this energy, allowing the vehicle to survive and potentially fly again. Without a durable heat shield, full and rapid reusability, the cornerstone of Starship’s design for frequent launches, satellite deployments, and deep-space missions, would remain impossible.
The tiles have long been a source of difficulty. On earlier test flights, a significant number of tiles detached during ascent due to vibration, aerodynamic loads, and imperfect attachment methods using pins and adhesives. Gaps between tiles allowed hot plasma to infiltrate, causing secondary damage and hot spots on the underlying structure.
These issues echoed challenges faced by NASA’s Space Shuttle, whose ceramic tiles required extensive, labor-intensive inspections and replacements between missions, preventing rapid turnaround. SpaceX has iteratively improved materials, standardized tile shapes, refined attachment techniques, added secondary ablative layers, and tested sealing methods such as “crunch wrap” felt to close gaps.
Progress was visible across Flights 10–12, with steadily better tile retention, yet questions remained about whether the system could support the minimal-refurbishment goal of rapid reuse.
Flight 13 on July 24 provided the decisive evidence. Ship 40 flew a deliberately more demanding profile with higher dynamic pressure to stress the heat shield beyond typical operational loads. It successfully deployed 20 operational Starlink V3 satellites, the first such payload on a Starship mission, performed an in-space Raptor engine relight, and executed a controlled reentry.

Cameras on six of the satellites and onboard sensors captured extensive imagery and data of the shield throughout the flight. The ship then achieved its softest splashdown to date in the Indian Ocean, remaining intact and floating rather than breaking apart or exploding as on prior missions. This allowed drone inspections and continuous telemetry of the heat shield in near-real time.
-
Post-flight analysis showed the majority of tiles remaining attached with only minor damage and limited plasma streaking at seams. Musk noted that the mission delivered “all the heat shield data we needed and then some.” Combined with visual inspections, these results underpinned his subsequent assessment that the core technical barriers to rapid reusability have been cleared. While refinements will continue, Flight 13 marked a pivotal step toward Starship’s operational future.
SpaceX COO Gwynne Shotwell outlined ambitious plans for Starlink Mobile during the company’s August 4 Earnings call, signaling a direct challenge to U.S. wireless giants like AT&T, T-Mobile, and Verizon.
Shotwell noted that the three companies generate roughly $600 billion in combined annual revenue. “I anticipate us to be able to acquire quite a few of their customers because I think our service will be better,” she said. “We will eliminate dead zones leveraging the satellites in orbit. It will be better during any natural disaster… I’m quite excited about Starlink Mobile.”

SpaceX intends to combine its satellite constellation with terrestrial infrastructure. The company has acquired about 65 MHz of spectrum from EchoStar and plans to deploy next-generation Starlink Mobile satellites in 2027, with upgraded service targeted for the end of that year.
Shotwell described the enhanced network, leveraging more satellites and spectrum, as potentially “100 times better” than the current direct-to-cell offering, which already supports basic texting and app-based voice/video in coverage gaps through partnerships. She also indicated plans for low-cost cellular base stations that could integrate with existing Starlink dishes, creating a hybrid system for broader capacity in urban, suburban, and rural areas.

For the general public, Starlink Mobile promises significant advantages. Satellite connectivity can fill gaps where traditional cell towers fail, delivering service in remote locations, mountains, or during outages caused by storms, wildfires, or infrastructure damage—conditions in which ground networks often collapse.
Users could enjoy more consistent coverage without relying solely on dense tower builds, potentially at competitive prices as SpaceX scales. The hybrid approach aims to support full mobile services, including higher-speed data, while working with unmodified smartphones over time.
These developments revive long-standing but unfounded rumors of a Musk-developed “Tesla phone.” Speculative claims of a “Pi Phone” or similar device with built-in Starlink connectivity have circulated for years on social media, often featuring fabricated images and details. Elon Musk has repeatedly denied any such plans, stating Tesla has no intention of entering the smartphone market unless forced by extreme circumstances with app stores.
No official product, filings, or development announcements have ever materialized; the rumors remain hoaxes.
The announcement quickly pressured telecom stocks. Shares of AT&T, Verizon, and T-Mobile fell between roughly 2 and 4 percent in after-hours and premarket trading as investors weighed the competitive threat from a hybrid satellite-terrestrial network.
While execution challenges remain—spectrum deployment, infrastructure rollout, and regulatory hurdles—Shotwell’s remarks mark SpaceX’s clearest signal yet of entering the consumer mobile market as a full competitor.

Venture capitalist Chamath Palihapitiya has cautioned investors shorting SpaceX shares, drawing a direct parallel to the intense short-selling pressure Tesla faced in its early public years.
Responding to reports of elevated short interest in the newly public rocket, satellite, and AI company, Palihapitiya noted that similar dynamics played out with Tesla, where aggressive short sellers ultimately “went broke.”
SpaceX (NASDAQ: SPCX) went public on June 12, 2026, in the largest IPO on record, pricing at $135 per share. Shares quickly surged to an all-time high of $225.64 just days later, briefly implying a valuation exceeding $2 trillion. The stock has since retreated sharply amid valuation concerns, lockup expiration fears, and broader market dynamics.
By early August, it traded near $108–$125, representing a roughly 50 percent decline from the peak and bringing the market capitalization closer to the $1.5–1.7 trillion range. On August 4, shares closed up more than 9 percent at $125.33 ahead of earnings before facing pressure in after-hours and premarket trading.
Short interest has climbed dramatically. According to S3 Partners data widely cited in market reports, short positions reached approximately 219.3 million shares by late July, about 34 percent of the limited public float of roughly 640 million shares, and represented a notional value of around $24.6 billion.
Utilization of shares available to borrow hit 95 percent, with borrow fees rising. This level of shorting exceeded the dollar value of short bets against Tesla at the time and built rapidly ahead of two catalysts: the company’s first post-IPO earnings and an August 6 lockup expiration that could free up to 911.5 million additional shares.

CEO Elon Musk has issued warnings of his own. In mid-July, as short interest approached one-third of the float, he posted that “the survival probability of firms who maintain a significant short position in SpaceX over time is very low,” reiterating his view that the company could ultimately be worth more than Earth if it achieves its goals.
On August 4, just before earnings, Musk responded to the latest short-interest data by saying, “I try to warn them, but they just double down.”
SpaceX delivered its first quarterly results as a public company after the close on August 4. Second-quarter revenue rose 92 percent year-over-year to $7.8 billion, beating consensus estimates near $6.8–6.9 billion.
The net loss narrowed to $541 million, or 9 cents per share, better than the roughly 23–24 cent loss expected. Starlink/connectivity contributed about $4.3 billion (up 66 percent), while the AI business generated $2.6 billion (up roughly 250 percent). Capital expenditures were heavy at $18.4 billion, largely tied to AI infrastructure. Management projected a $100 billion annualized revenue run rate by year-end 2026 and outlined a path toward $1 trillion in annual revenue by 2030.
The combination of Chamath’s historical reminder, Musk’s repeated alerts, and the company’s ambitious growth targets underscores the high-stakes debate surrounding SPCX. Short sellers are positioned for near-term supply pressure from the lockup, while long-term bulls point to Starlink scale, Starship progress, and AI compute expansion as reasons the bears may ultimately face the same fate as many early Tesla skeptics.
