SpaceX to build small version of BFR’s spaceship for use on Falcon 9, says Elon Musk
SpaceX CEO Elon Musk has taken to Twitter to announce a new development program: in order to gain experience with the new design and recovery strategy, SpaceX engineers and technicians will apparently build a miniature version of BFR’s winged spaceship able to launch atop Falcon 9 or Falcon Heavy.
According to Musk, the company aims to conduct the first orbital flight of this mini-BFS as early as June 2019, just eight months away.
Mod to SpaceX tech tree build: Falcon 9 second stage will be upgraded to be like a mini-BFR Ship
— Elon Musk (@elonmusk) November 7, 2018
Described as a “SpaceX tech tree build”, Musk seems to be implying that the strategic purpose of this new development is to act as a stepping stone between Falcon 9 and BFR, two dramatically different launch vehicles relying on a variety of entirely distinct technologies. Based on the fact that Musk believes the mini-BFS could reach orbit as early as June 2019, it seems likely that the miniature spaceship will essentially just be a strengthened Falcon 9 upper stage with fins and a heat shield attached versus a more extreme departure, where the stage would literally be a mini-BFS.
In the latter scenario, SpaceX could use the opportunity to extensively test – albeit on a smaller scale – a number of immature BFR technologies, including all-composite propellant tanks, autogenous pressurization, a sea level-optimized rocket engine on an orbital upper stage, methane and oxygen (methalox) propellant, actuatable tripod fins, new heat shield materials, and more. If SpaceX has been working on this for several months, there is still a chance that those technologies will be tested on this step-change Falcon 9 S2 variant, but it seems improbable that Musk would have been able to stay totally silent on the plans during his September 2018 update to the BFR program.

Falcon 9 upper-stage recovery
Going off of what little information we have, it seems more likely that the “mini-BFR ship” described by Musk is an effort to realize Falcon 9 upper stage recovery and test BFR’s orbital spaceship recovery strategies than it is an extensive development platform for all critical BFR technologies. Prior to today’s tweet, Musk announced early this year (April, to be precise) that SpaceX would attempt to recovery Falcon 9’s upper stage with a “giant…balloon”, or an inflatable decelerator to use the technical terminology.

Given this new development, it’s unclear if those plans are still on – as a small spaceship, Falcon 9’s upper stage would likely be able to reenter Earth’s atmosphere without the need for something like a single-use inflatable decelerator, which would have always been a suboptimal crutch for the recovery of any orbital spacecraft, be it Falcon 9 or BFR. With this new plan, it appears that SpaceX wants to kill at least two birds with one stone, building a platform capable of flight-testing a handful of new technologies critical to BFR’s success while also potentially realizing the dream of a fully-reusable Falcon 9.

Given recent reports from Reuters that Musk has demanded that SpaceX’s Starlink team work towards the first launch of an operational batch of satellites by mid-2019, his target date for a mini-BFS Falcon 9 upper stage is likely no coincidence. Given the potential risk of being the first to launch on an unproven variant of Falcon 9, it’s possible (if not probable) that SpaceX will conduct its own launch of the rocket prior to flying paying customers – a perfect way to avoid wasting that launch would be risking a few of SpaceX’s own Starlink satellites in place of a customer’s payload.
Won’t land propulsively for those reasons. Ultra light heat shield & high Mach control surfaces are what we can’t test well without orbital entry. I think we have a handle on propulsive landings.
— Elon Musk (@elonmusk) November 7, 2018
Musk seems to be confident that SpaceX has effectively ‘solved’ propulsive rocket landings, stating that the purpose of this new variant will be dedicated to testing an “ultra light heat shield and high Mach control surfaces”. Judging from a number of recent job postings focused on new thermal protection systems (and affixing them to composite structures) and an official request for information (RFI) from NASA Ames about its lightweight TUFROC heat shield material, this is a major focus and one of several critical paths for BFR development.

SpaceX to report first-ever earnings today: here’s what to expect
Elon Musk’s space exploration company, SpaceX (NASDAQ: SPCX), is set to report its earnings for the second quarter today in what will be its first-ever earnings call since going public in July.
SpaceX is trading down roughly 25 percent from its IPO. These early stock signals are usually a bit tumultuous, and considering this is the first company actively launching rockets that is available on the stock exchange, investors might have a tendency to be a bit skittish.
However, there are going to be some details that investors will hear for the first time today on the earnings call. Here’s what to look for:
Wall Street Expectations
Revenue is expected to fall somewhere around $6.8 billion, and will be heavily driven by Starlink, which is SpaceX’s widely popular satellite internet platform that has been adopted by numerous airlines, cruise ships, and other maritime operations. It is also available for consumers at home or in their cars.
Earnings Per Share (EPS) expectations fall at a net loss of $0.23 per share. Wall Street sees this as a total net loss of roughly $1.9 billion.
EBITDA is expected to come in between $2 billion and $2.1 billion.
What Investors Want to Know
Tesla uses the Say platform to help work with both retail and institutional investors to answer relevant and quality questions that address concerns or questions that they might have.
However, SpaceX is doing things differently, as the company launched its own Investor Relations website where these questions are being fielded. Just like the Tesla questions, they seem to be less focused on the operational tasks and overall progress of the company, and more novelty.
Here are the top five:
- Has the team thought about what possibilities there are with your mascot Asteroid? Whether it’s starting additional foundations for kids in its name, helping kids learn about space, etc. Kids are our future, and Asteroid would be a fun and easy way to help.
- Baby Asteroid is already making a difference through charity around the world. Could SpaceX take it even further with programs that inspire kids to explore space?
- SpaceX has some legendary vehicle names. Would you ever allow the public to name a Starship, even knowing there is a 99% chance it becomes Shipy McShipface?
- When can we expect to see more footage of the Human Landing System?
- Will Asteroid (your mascot) go to Mars?
SpaceX will report its earnings today, August 4, at 4:30 P.M. EDT.

SpaceX’s biggest test yet arrives this week and it’s not a rocket launch
SpaceX will report second quarter results after the market closes on Tuesday, August 4, marking the first time the company has opened its books to the public since its record IPO in June. Management will host a live audio only webcast at 4:30 p.m. ET, streamed on X, with no dial in option.
The debut carries more weight than a typical first quarter as a public company. Two trading days after the release, on August 6, the first tranche of SpaceX’s lockup expires, freeing roughly 911.5 million insider and employee shares, worth well over $100 billion at current prices and the largest such release in Wall Street history. A second, larger tranche tied to the stock trading 30 percent above its $135 IPO price never triggered, since shares have spent most of July trading below that price.
Wall Street’s models point to revenue near $6.9 billion for the quarter, up sharply from the $4.69 billion SpaceX reported in the first quarter, with a narrower per share loss than the $1.27 posted three months earlier, according to estimates compiled by Motley Fool. Those numbers will be the first look at how SpaceX’s three segments, Starlink, launch and AI, are performing independently.

Investors heading into the call have a specific list of questions. How many net new Starlink subscribers did SpaceX add after ending March with 10.3 million, and is average revenue per user holding up as the service expands into lower income markets. How much of the AI segment’s revenue reflects contract signings with Anthropic, Google and Reflection AI this year, deals that combined could annualize to nearly $28 billion if fully ramped. Whether capital expenditures, which nearly doubled in the AI segment alone between 2024 and 2025, are still accelerating or starting to plateau. And whether management offers any forward guidance at all, something SpaceX has never done publicly.
The report will also land days after Elon Musk publicly denied a Wall Street Journal report describing internal planning to separate Tesla’s China business ahead of a potential Tesla-SpaceX merger. Whether Musk or SpaceX executives address that speculation on the call, even indirectly, maybe something investors will be listening for on Tuesday.
As Teslarati reported after Musk’s own warning to short sellers last week, the CEO has made clear he expects skeptics to be proven wrong over time. Tuesday will be the first chance for the numbers themselves to make that case.

SpaceX’s Starship just got filmed by its own cargo
SpaceX released new footage of Starship in space captured by the Starlink satellites it deployed.
SpaceX released a new video Friday evening showing Starship from an angle showcased by its own Starlink satellites, watching the rocket drift away in orbit.
The 65 second clip, posted on X, stitches together footage from four cameras mounted on a single Starlink V3 satellite. It opens with a close view of Starship’s 171 foot upper stage, still catching sunlight, then pulls back as the two spacecraft separate.
The footage comes from Starship’s 13th flight test, which launched July 24 from Starbase after a scrubbed attempt and an abort caused by an engine issue the week before. When Flight 13 finally flew, it carried the first batch of functional Starlink V3 satellites Starship has ever deployed, twenty of them, with six equipped with cameras meant to scan the ship’s heat shield during reentry.

Flight 13 checked most of its boxes. Starship deployed all 20 satellites, relit a Raptor engine in space, and splashed down softly in the Indian Ocean off Western Australia. Musk’s longer term plan calls for a Starlink V3 constellation of 100,000 satellites, according to a recent FCC filing, with Starship as the only vehicle capable of launching them at the volume that requires. Each Starship flight is designed to carry up to 60 V3 satellites once the vehicle reaches routine service, well beyond what Falcon 9 can carry in a single mission.
Starship is next expected to fly with an attempt at catching the ship itself with the launch tower’s mechanical arms, a maneuver SpaceX has so far reserved for the Super Heavy booster.
