DeepSpace: Firefly set for smallsat industry’s second place trophy, Rocket Lab leads the pack
This is a free preview of DeepSpace, Teslarati’s new member-only weekly newsletter. Each week, I’ll be taking a deep-dive into the most exciting developments in commercial space, from satellites and rockets to everything in between. Sign up for Teslarati’s newsletters here to receive a preview of our membership program.
In the race to a field dedicated smallsat launch vehicles, New Zealand startup Rocket Lab has already won first place, a fact that has been discussed several times in past Deep Space issues. After completing its first launch of 2019 on March 28th, Rocket Lab’s Electron rocket is ready for another mission as early as May 4th, a good sign for the company’s planned monthly launch cadence.
Despite Rocket Lab’s major success, there is plenty of room for additional competitors and/or complementary vehicles. Electron’s maximum payload hovers around ~225 kg (500 lb) to low Earth orbit (LEO), limiting its usefulness for any payloads that are larger than truly tiny satellites or in need of higher orbits. Also discussed on DeepSpace, there are 10+ serious startups with funding and hardware in work attempting to build said smallsat launch vehicles, ranging from the extremely tiny (Vector: 60 kg to LEO) to much larger rockets from companies like Relativity, ABL Space, and more. Firefly Space, however, is the startup that has arguably broken away from the pack in the last few months, firmly setting itself up to be second in line behind Rocket Lab.
Build, test, qualify
- Firefly’s major leaps forward came in December 2018 and then April 2019, both related to testing the completed upper stage of the company’s Alpha rocket.
- In December, the upper stage ignited for the first time. In April, the same upper stage successfully performed a mission-duration static fire that lasted a full 300 seconds (five minutes), the same length required for a rocket to reach orbit after separating from Alpha’s first stage.
- For any launch vehicle development program, the first successful mission-duration test fire of an integrated rocket stage is arguably one of the most important milestones, second only to the same hardware’s inaugural launch.
- Simultaneously, Firefly began integrated testing of the thrust section and Reaver engines that will be the basis of Alpha’s first stage. The rocket’s Lightning second stage engine has been tested extensively at this point in development, although the stage’s lone engine produces a maximum of ~70 kN (~16,000 lbf) of thrust.
- The booster’s four Reaver engines will each produce ~170 kN (55,000 lbf) of thrust, around three times as much as Lightning. Alpha’s second stage is critical, but its first stage is arguably far more complex.
- Despite the relative power differential, it’s still worth noting that Alpha’s entire first stage (736 kN/166,000 lbf) will be significantly less powerful than a single one of Falcon 9’s nine Merlin 1D engines (941 kN/212,000 lbf).
- Although Alpha is far smaller than rockets like Falcon 9 or Atlas V, it will nominally be capable of launching 1000 kg to an altitude of 200 km (LEO) or ~650 kg to a 500-km sun-synchronous orbit (SSO). This translates to around 4.2X the performance of Rocket Lab’s Electron at 2.5X the cost per launch ($15M vs $6M).
- Assuming no payload capacity is wasted, Alpha could thus be almost 50% cheaper than Electron when judged by cost per kilogram to orbit.
- Of course, this comparison ignores the fact that Firefly will have to far more heavily rely on booking co-passenger satellites to keep Alpha launch prices competitive with Electron.
- If exactly 1000kg or 630kg of cargo can’t be booked each launch, the expendable Alpha’s $15M launch cost will be distributed over less payload, raising costs for each customer. In other words, the competitive advantages of Alpha are almost entirely associated with its ability to launch payloads outside of Electron’s capabilities, as are its potential weaknesses.

The sweet spot
- In theory, Firefly Alpha’s could find itself in a relatively sweet spot, where the rocket’s launch costs are not so high that dedicated rideshare missions become intractable (i.e. Spaceflight’s SSO-A launch on Falcon 9) but its payload performance is still good enough to provide access to a huge swath of the space launch market.
- Firefly also has plans to develop a heavier launch vehicle based on Alpha, known as Beta. Conceptually equivalent to SpaceX’s Falcon Heavy, Beta would use three Alpha boosters and a significantly upgraded second stage and would be able to launch 4000 kg to LEO or 3000 kg to SSO.
- Regardless of Firefly’s grander aspirations, Alpha is poised to capitalize on the simple fact that it will be the second commercially viable smallsat launch vehicle to begin operations. Alpha’s first orbital launch attempt could occur as early as December 2019, although slips into early 2020 are to be expected.
- At that point, Rocket Lab’s Electron will be the only serious competition on the market. Relativity’s Terran and ABL Space’s RS-1 rockets plan to offer a competitive ~1250 kg to LEO or ~900 kg to SSO, but their launch debuts are tentatively scheduled no earlier than late 2020.
- If Alpha’s development continues smoothly, Firefly could easily have a solid 12-month head start over its similarly-sized competitors,
- Up next for Alpha is a similar campaign of tests focused on the first integrated booster, including tests fires and an eventual mission-duration qualification test.
Mission Updates
- SpaceX’s CRS-17 Cargo Dragon resupply mission has slipped an additional four days from April 30th to May 3rd (3:11 am EDT, 07:11 UTC) after the International Space Station (ISS) began suffering serious (but non-threatening) electrical issues. Additional launch delays could follow if the issue is not resolved in the next few days.
- The first operational Starlink launch remains firmly on track for NET mid-May. According to SpaceX, all Flight 1 satellites are already in Florida, while the FCC approved the company’s modified constellation license – permitting Starlink operations after launch – on April 26th.
- Due to CRS-17’s launch delays, the availability of SpaceX’s LC-40 pad will now likely be the main limiting factor for the Starlink-1 launch date.
- SpaceX’s second West Coast launch of 2019 – carrying Canada’s Radarsat Constellation – is now expected to occur no earlier than mid-June and will reuse Falcon 9 B1051.
- SpaceX’s launch of Spacecom’s Amos-17 spacecraft is now scheduled no earlier than July. Falcon Heavy Flight 3 is tentatively scheduled for launch as early as June 22 – all three boosters should be on site in Florida within the next week or two.

The third Falcon Heavy center core – believed to be B1057 – was spotted eastbound in Arizona on April 16th. On April 26th, SpaceX confirmed that the booster completed its acceptance static fire test at the company’s McGregor, TX facilities, a sure sign that all of Falcon Heavy Flight 3’s major components should be in Florida within the next few weeks.

Tesla has its answer to grow its automotive sales over the next few years, TD Cowen analyst Itay Michaeli says, but it just has to bring it to the U.S.
On Thursday, Michaeli reiterated his $490 price target and the ‘Buy’ rating he already held on Tesla stock (NASDAQ: TSLA). However, its automotive division has struggled to show sequential growth over the past few years, mostly due to its focus on AI and Full Self-Driving. Tesla already axed two of its lower-volume vehicles with the Model S and Model X earlier this year.
However, Tesla does not need to engineer an entire new vehicle to trigger an upward tick in sales; it just has to bring it from China to the U.S., Michaeli said.
He is talking about the Model Y L, a slightly larger version of the all-electric crossover that is already available in China. U.S. customers have been pleading with CEO Elon Musk to bring it to the country since its launch in Asia last year, but he’s not convinced of it because of the advent of self-driving and its importance in this particular market.
The problem is that Tesla owners have been requesting something larger that could fit a typical American family. The Model Y L is slightly larger than the standard Model Y, but some are concerned that it could still be too small to fit what most people might need.
Instead, they have asked for a full-size SUV from Tesla.
Tesla gives big hint that it will build Cyber SUV, smaller Cybertruck
Nevertheless, the Model Y L still presents a great opportunity for Tesla in the U.S., and Michaeli says that there is an additional sales opportunity of about 100,000 units, with demand potential falling somewhere between 60,000 and 135,000 units.
TD Cowen’s note to investors also analyzed that Tesla’s growth could come from a stock perspective as well, positively impacting the stock price, as it has been widely reliant on vehicle sales, even though Tesla has truly phased itself away from that being an important metric.
Tesla stands to gain greatly from the introduction of the Model Y L in the U.S., but only if Elon Musk sees it as a viable fit for the market. Families may need to see Tesla bring something larger to the U.S., or they might be forced to buy from another automaker that offers something that fits is needs for more interior space to haul around the kids.
Tesla Hardware 3 owners are set to get a new Full Self-Driving version this month as the company plans to release what it is referring to as v14 Lite.
The rollout is not yet confirmed for June, but Tesla executives have stated on several occasions that this more refined FSD iteration will work with their cars and increase its capabilities.
This comes after Tesla admitted during its last Earnings Call that these Hardware 3 vehicles would not be able to achieve Full Self-Driving, something that they did not know when they bought these cars. We regularly receive messages from Hardware 3 owners asking when v14 Lite will come out, what they should expect, and whether it is worth it to upgrade the self-driving computer or buy a new car altogether.
Following future rollout of FSD V14 Lite for HW3 vehicles in the US, we plan on expanding V14 Lite to additional international markets.
This update ensures that HW3 vehicle owners will continue to benefit from ongoing software updates.
Since international rollout is subject to…

It is hard not to feel for them; Tesla CEO Elon Musk said at the company’s 2019 Autonomy Day that all vehicles produced at the time, including Hardware 3 cars, had “all the hardware necessary, compute and otherwise, for Full Self-Driving.”
Musk also said in March of that year that, “Anyone who purchased Full Self-Driving will get FSD computer upgrade for free.”
Anyone who purchased full self-driving will get FSD computer upgrade for free. This is the only change between Autopilot HW2.5 & HW3. Going forward “HW3” will just be called FSD Computer, which is accurate. No change to vehicle sensors or wire harness needed. This is v important. https://t.co/lICMpT7xnX
— Elon Musk (@elonmusk) March 29, 2019
However, during the Q1 2026 Earnings Call, Musk admitted that Hardware 3 vehicles would not be capable of FSD, as “It has only 1/8th the memory bandwidth of Hardware 4, and memory bandwidth is one of the key elements needed for unsupervised FSD.”
Tesla has made some effort to remedy these Hardware 3 owners by offering:
- Discounted trade-ins toward AI4 cars
- Hardware retrofits, which would replace the self-driving computer and upgrade all cameras
- Full Self-Driving v14 Lite
The issue is that many of these owners were led to believe their cars would be capable of unsupervised self-driving. Now, they’re left scrambling for options, and while there are several, they will all require more money out of their pockets.
Expectations for Tesla v14 Lite for Hardware 3 Owners
The big differences between the AI4 v14 and v14 Lite for Hardware 3 owners will stem primarily from hardware constraints. Tesla developed v14 Lite with an optimized frame of mind; the v14 neural nets are toned down to run on an HW3 computer.
Tesla v14 will use the same behavior, but its limits will be hardware-related, especially given that the cameras on HW3 vehicles are lower-resolution.
Tesla reveals its plans for Hardware 3 owners who are eager for updates
This will result in potentially more edge cases due to the lower quality perception and less long-range detection, but reaction time and overall confidence should be more refined.
There should also be a handful of additional features that are available on AI4 cars, such as:
- Starting Full Self-Driving from Park
- Auto Shift
- Streaks
- Speed Profiles
- Improved Dynamics, like Pulling Over for Emergency Vehicles
Tesla plans to release v14 Lite this month, but we are all familiar with how the company can be with timelines. Additionally, if v14 Lite has not proven to be ready for a wide release, Tesla will slam the brakes on the rollout.
We would anticipate that Tesla is testing v14 Lite internally, and likely has been for several months.

SpaceXAI just launched into your kitchen with their new app
SpaceXAI just powered its first consumer app and it predicts what you want to buy.
SpaceXAI just made its first move into consumer AI, and it involves your grocery cart. On June 3, 2026, Gopuff and SpaceXAI announced the launch of Go, a Grok-powered shopping assistant built directly into the Gopuff app that predicts what you need before you even start searching for it.
Gopuff is an instant delivery platform that operates more than 400 micro-fulfillment centers across the U.S., delivering everyday essentials, snacks, drinks, and household items in as little as 15 minutes. It is not a restaurant delivery app or a marketplace. It owns its inventory, controls its warehouses, and handles its own logistics, which means it has built one of the most detailed consumer behavior datasets in retail over its 13-year history.
Go combines SpaceXAI’s advanced reasoning, voice, and image generation models with Gopuff’s dataset of hundreds of millions of orders and real-time cultural signals from X to prepare a suggested cart the moment a customer opens the app. It learns each shopper’s habits and automatically builds a personalized cart based on time of day, location, order history, and real-time indicators. Returning customers can check out with a single tap.
Rather than searching for specific items, users can describe a situation like a game-day party or the desire for a healthy breakfast and Go will assemble a cart automatically. It can also predict when shoppers are running low on items like coffee or paper towels and have them packed and delivered in under 15 minutes. Grok voice integration lets users talk to the app in plain conversational language and check out completely hands-free.
Gopuff co-founder and co-CEO Yakir Gola said: “Today, we believe the greatest friction left in commerce is not delivery or instantaneous access to the essentials customers need. It’s the moment before: the thinking, the deciding, the remembering. We’re combining Gopuff’s demand intelligence with xAI’s frontier reasoning to create an everyday shopping experience that feels like a true extension of you.”
Why SpaceX just made a $60 billion bet on AI coding ahead of historic IPO
The timing carries context beyond the product launch. SpaceXAI was formed after SpaceX completed an all-stock merger with Elon Musk’s xAI earlier this year, folding one of the most advanced AI labs in the world into the same corporate structure as the company preparing what could be the largest IPO in history. SpaceXAI is dipping into consumer-focused AI just as it prepares for its public debut, and while Musk has openly discussed building an everything app, this launch uses Grok to power another company’s product rather than launching a standalone consumer platform. Every consumer-facing deployment of Grok ahead of the IPO roadshow adds tangible evidence that SpaceXAI is not just an infrastructure play but a direct competitor in the AI application layer where OpenAI and Google are already fighting for dominance.
