In a burst of activity that should probably be expected at this point but still feels like a complete surprise, SpaceX technicians took a major step towards completing the first Starship hopper prototype by combining the last two remaining sections (aft and nose) scarcely six weeks after assembly began.

SpaceX CEO Elon Musk also took to Twitter late last week to offer additional details and post what appears to be the first official render of Starship’s hopper prototype, which is now closer than ever before to looking like the real deal thanks to the incredible drive of the company’s southernmost employees. With the massive rocket’s rough aeroshell and structure now more or less finalized, Musk’s targeted February/March hop test debut remains ambitious to the extreme but is now arguably far from impossible.

Where there was literally just a tent and some construction equipment barely eight weeks ago, SpaceX’s Boca Chica facilities now sport one of the most bizarre developments in recent aerospace history — a vast, ~30 ft (9m) diameter rocket being built en plein air out of tubes and sheets of common steel. At the current pace of work, 24 hours is often enough for wholly unexpected developments to appear, and this Starship hopper (Starhopper) is beginning to look more and more like its concept art as each day passes.

Aside from a few well-earned slow days last weekend, SpaceX technicians, engineers, and contractors have spent the last week or so shaping Starhopper into a form more reminiscent of the conceptual render (clearly hand-painted) Musk posted on Saturday. This primarily involved stacking a tall conical nose section atop a separate cylindrical body section, followed by gradually cladding both the aft section’s legs and barrel in sheets of stainless steel, presumably intended to improve both its aesthetic and aerodynamic characteristics.

Notably, technicians have installed two out of three (?) aerodynamic shrouds at the top of each steel tube leg, bringing Starhopper’s appearance even closer to the smooth and polished aesthetic of its conceptual sibling.

Starhopper’s hopped-up hop test ETA

Musk later replied to a question related to Starhopper’s near-term schedule and stated that the nominal target for its first flight test was – almost unfathomably – four weeks away, although he admitted in the same response that that would probably translate into eight weeks due to “unforeseen issues”, placing the actual launch target sometime between February and March 2019. Just to reiterate, the site Starhopper is currently located on was quite literally empty – aside from the temporary tent – in late November 2018, barely more than six weeks ago.

To plan to go from a blank slate to actual integrated flight tests of a rocket – no matter how low-fidelity – that is 9m (~30 ft) in diameter, at least 40m (~130 ft) tall, could weigh as much as 500 tons (1.1M lbs), and may produce ~600 tons (~1.35M lb/f) of thrust at liftoff is extraordinarily ambitious even for SpaceX. At the end of the day, significant delays to Musk’s truly wild timeline are very likely, but it seems entirely possible at this point that Starhopper really could begin its first hop tests in the first half of 2019, kicking off a test program currently aiming for flights as high as 5 km (3.1 mi) and as long as 6 minutes.

A whole range of things will have to go perfectly right for a timeline as ambitious as this to be realized, including but not limited to successfully acceptance-testing three brand new and recently-redesigned Raptor engines, the completion of Starhopper’s unfamiliar structures, propellant tankage, plumbing, and avionics, and the completion of a rough launch and landing pad and integration facilities, if needed. Aside from those big ticket items, many dozens of other smaller but no less critical tasks will have to be completed with minimal to no unforeseen hurdles if hop tests are to begin just a few months from now.

Regardless, SpaceX has pulled off miraculous tasks much like this in its past, and the possibility that the company’s brilliant, dedicated, and admittedly overworked employees will do so again should not be discounted.

Tesla Cybertruck fleet takes over at SpaceX’s Starbase

Interestingly, the Cybertruck uses the same exterior, a stainless steel alloy, as SpaceX rockets. This synergy between the two companies and their very different products shows a very unified mentality between Musk companies.

Tesla Cybertrucks have taken over at SpaceX’s Starbase facility in Texas, as hundreds of the all-electric pickup trucks were spotted late last week rounding out a massive fleet of vehicles.

The Cybertruck fleet is geared toward replacing gas vehicles that are used at Starbase for everyday operations. The only surprise about this is that it was not done sooner:

Deliveries have been going on for a few weeks, as Cybertrucks have made their way across the state of Texas from Austin to Starbase so they could be included in SpaceX’s fleet of vehicles at the facility.

Interestingly, the Cybertruck uses the same exterior, a stainless steel alloy, as SpaceX rockets. This synergy between the two companies and their very different products shows a very unified mentality between Musk companies.

However, there are some other perspectives to consider as SpaceX is utilizing such a massive fleet of Cybertrucks. Some media outlets (unsurprisingly) are seeing this as a move of weakness by both Tesla and SpaceX, as the aerospace company is, in a sense, “bailing out” lagging sales for the all-electric pickup.

It’s no secret that Tesla has struggled with the Cybertruck this year, and deliveries have been underwhelming in the sense that the company was anticipating between 1 million and 2 million orders for the vehicle before it was widely produced.

A lot of things changed with the Cybertruck between its 2019 unveiling and 2023 initial deliveries, most notably, price.

The price of the Cybertruck swelled significantly and priced out many of those who had pre-ordered it. Some have weighed the option of whether this purchase was a way to get rid of sitting inventory.

However, it seems more logical to consider the fact that SpaceX was likely always going to transition to Teslas for its fleet, especially at Starship, at some point.

It doesn’t seem out of the question that one Musk company would utilize another Musk company’s products, especially considering the Cybertruck has been teased as the vehicle that would be present on Mars.

SpaceX achieved its 100th Starlink mission of the year on Friday, October 31, marking another milestone for 2025. 

A Falcon 9 rocket carrying 28 Starlink broadband satellites successfully lifted off from Vandenberg Space Force Base in California at 4:41 p.m. ET, carrying another 28 Starlink satellites to Low Earth Orbit (LEO).

Falcon 9 booster’s 29th flight

Roughly 8.5 minutes after liftoff, the Falcon 9’s first stage touched down on the drone ship Of Course I Still Love You in the Pacific Ocean. This marked the booster’s 29th flight, which is approaching SpaceX’s reuse record of 31 missions.

This latest mission adds to SpaceX’s impressive 138 Falcon 9 launches in 2025, 99 of which were dedicated to Starlink, according to Space.com. The company’s focus on reusing boosters has enabled this breakneck pace, with multiple launches each week supporting both Starlink’s expansion and external customers.

Starlink’s network continues massive global expansion

Starlink remains the largest active satellite constellation in history, with more than 10,000 satellites launched, nearly 8,800 of which are currently active. SpaceX recently achieved Starlink’s 10,000-satellite milestone. With 100 Starlink missions completed for 2025, space enthusiasts have noted that SpaceX has successfully launched 2,554 Starlink satellites so far this year.

SpaceX has revealed that it has completed 49 major milestones for NASA’s Human Landing System (HLS) program, marking significant progress in the development of the Starship lunar lander that will deliver astronauts to the Moon. 

The updates were detailed in SpaceX’s new blog post To the Moon and Beyond, which was recently posted on the private space company’s official website.

As noted by SpaceX, the 49 milestones that were completed by its HLS team were “tied to developing the subsystems, infrastructure, and operations” needed to safely land humans back into the lunar surface. SpaceX noted that it has only received funding on contractual milestones that have been successfully completed, the vast majority of which have been achieved on time or ahead of schedule.

Following are highlights of SpaceX’s completed milestones, as per the company’s post.

  • Lunar environmental control and life support and thermal control system demonstrations, using a full-scale cabin module inhabited by multiple people to test the capability to inject oxygen and nitrogen into the cabin environment and accurately manage air distribution and sanitation, along with humidity and thermal control. The test series also measured the acoustic environments inside the cabin
  • Docking adapter qualification of the docking system that will link Starship and Orion in space, an androgynous SpaceX docking system capable of serving as the active system or passive system and based on the flight-proven Dragon 2 active docking system
  • Landing leg drop test of a full-scale article at flight energies onto simulated lunar regolith to verify system performance and to study foot-to-regolith interaction
  • Raptor lunar landing throttle test demonstrating a representative thrust profile that would allow Starship to land on the lunar surface
  • Micrometeoroid and orbital debris testing of shielding, insulation, and window panels, analyzing different material stackups that will be used to protect Starship from impact hazards and harsh thermal conditions
  • Landing software, sensor, and radar demonstrations testing navigation and sensing hardware and software that will be used by Starship to locate and safely descend to a precise landing site on the Moon
  • Software architecture review to define the schematic of major vehicle control processes, what physical computers they will run on, and software functions for critical systems like fault detection, caution and warning alerts, and command and telemetry control
  • Raptor cold start demonstrations using both sea-level and vacuum-optimized Raptor engines that are pre-chilled prior to startup to simulate the thermal conditions experienced after an extended time in space
  • Integrated lunar mission operations plan review, covering how SpaceX and NASA will conduct integrated operations, develop flight rules and crew procedures, and the high-level mission operation plan
  • Depot power module demonstration, testing prototype electrical power generation and distribution systems planned to be used on the propellant depot variant of Starship
  • Ground segment and radio frequency (RF) communications demonstration, testing the capability to send and receive RF communications between a flight-equivalent ground station and a flight-equivalent vehicle RF system
  • Elevator and airlock demonstration, which was conducted in concert with Axiom to utilize flight-representative pressurized EVA suits, to practice full operation of the crew elevator which will be used to transfer crew and cargo between Starship and the lunar surface
  • Medical system demonstration covering the crew medical system on Starship and the telemedicine capability between the ground and crew
  • Hardware in the loop testbed activation for the propellant transfer flight test which uses a testbed with flight representative hardware to run simulations for the upcoming propellant transfer flight test

Ultimately, SpaceX’s message is clear. With its plans for a simplified architecture, the timeframe of the first crewed lunar landing of the current century could happen sooner than expected.

Musk definitely seems determined to prove skeptics wrong, with the CEO declaring on X that Starship will be the vehicle that would pave the way for the buildout of a base on the Moon. “Starship will build Moonbase Alpha,” Musk wrote.
