DeepSpace: Rocket Lab ready for first commercial launch of 2019, an innovative DARPA spacecraft
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.

Now approximately four months distant from the inaugural commercial launch of Rocket Lab’s Electron rocket, the company is ready – following many weeks of customer-side delays – to conduct its first launch of 2019, aiming to place an experimental DARPA-funded satellite into low Earth orbit (LEO).
If all goes as planned with the launch and experimental spacecraft’s orbital operations, Defense Advanced Research Projects Agency (DARPA) hopes to use the mission to qualify a currently-untested technology that could ultimately enable the production of massive communications and sensing antennas that can fit on relatively tiny satellites. Known as R3D2 (ha…ha…), the mission also effectively serves as the latest operational debut of DARPA’s growing interest and involvement in spaceflight-related industries, nominally proving that the agency is capable of leaning on established companies and startups to rapidly design, build, and fly satellites. Barring any additional launch delays from DARPA’s preparations, Rocket Lab hopes to launch Electron around the end of this week – likely March 22-24 – to kick off what will hopefully be a busy and productive year for the newly operational launch provider.
DARPA in Space
- Originally targeted for sometime in the second half of February, the R3D2 mission – Electron’s fifth planned launch in 18 months – has suffered several weeks of delays due to issues faced by DARPA during satellite delivery and pre-launch preparations.
- Aside from a general hint that the satellite arrived a few weeks later than planned and an official statement from Rocket Lab that “DARPA’s payload team is conducting final ground station configuration work over the coming days”, the process appears to be going rather smoothly.
- Weighing in at roughly 150 kg (330 lb), the R3D2 spacecraft – barring the quiet inclusion of co-passengers – will be the first launch of Electron dedicated to a single satellite. In fact, 150 kg is actually the maximum listed payload that Electron is capable of launching to a 500 km (310 mi) sun-synchronous orbit (SSO), providing a functional ‘ceiling’ for the ultimate destination of DARPA’s satellite.
- R3D2’s primary purpose will be to extensively test a brand new antenna technology and thus prove (hopefully) that the in-space deployment mechanism and unique material composition function as designed. Likely no more than 1-2 feet (~50 cm) across, the definitively small satellite will attempt to deploy an antenna many times larger than itself.
- Made out of a material known as Kapton, the deployable antenna will reach a maximum diameter of 2.25 m (7.4 ft), fairly large even when compared with antennas used on satellites many dozens of times more massive.
Rocket Lab’s Biggest year yet
- Although the company is off to a relatively slow start, as many as eleven Electron missions – including R3D2 – are at least tentatively manifested for launches in 2019.
- In November and December of 2018, Rocket Lab further demonstrated that it is more than capable of a respectable monthly launch cadence, particularly impressive for a rocket conducting its third and fourth missions ever. If Rocket Lab can more or less sustain that cadence after DARPA’s R3D2, the company could ultimately complete as many as 8-10 launches this year.
- Ultimately, founder and CEO Peter Beck says that Rocket Lab and Electron will eventually target dozens of annual launches per year and a weekly launch cadence from an array of launch facilities.
- Earlier this year, Rocket Lab officially announced that it had come to an agreement with the state of Virginia to build its second launch complex (LC-2) at Wallops Flight Facility (also known as the Mid-Atlantic Spaceport). If construction proceeds apace, the company’s first US-based Electron launch could occur before the end of 2019.
- DARPA’s goal with R3D2 – and its interest in space and small satellites in general – should ultimately benefit the entire spaceflight industry, potentially paving the way for the design and production of small satellites with technical capabilities that far outstretch their compact nature.
- Reliable and affordable deployable structures are becoming a growing focus of a number of young and old spaceflight companies, ranging from heavyweights like SSL/Maxar to new startups like Oxford Space Systems.
- Unlike most modern defense and aerospace technology procurement, DARPA is also distinctly focused on streamlining the process of designing, building, and launching spacecraft. To do so, the agency plans to rely heavily on established commercial entities to optimize speed and affordability will still ultimately producing innovative space systems and pushing the state of the art forward.
- Aside from closely involved projects like R3D2, DARPA – through a program called Blackjack – is also extremely interested in a number of LEO communications constellations proposed in the last few years by companies like SpaceX, OneWeb, and Telesat, and has already awarded a series of small contracts with several to begin the program’s earliest phases.
Mission Updates
- Completed on March 8th, SpaceX’s near-flawless Crew Dragon launch, space station rendezvous, and recovery is likely the last of the company’s orbital launch activities for the month of March.
- The second launch of Falcon Heavy – the rocket’s commercial debut – is currently expected to occur as early as April 7th
- After Falcon Heavy, SpaceX has at least one other launch – Cargo Dragon’s CRS-17 resupply mission – firmly scheduled for April (April 25th), as well as the more tenuous possibility of the first dedicated Starlink launch occurring as early as late April.
Photos of the Week:

Tesla Semi gets strange-but-understandable comparison from Jay Leno

The Tesla Semi recently received a strange-but-understandable comparison from automotive enthusiast and former long-time late-night television show host Jay Leno.
In a recent interview with MotorTrend, legendary comedian and automotive enthusiast Jay Leno shared his impressions after driving Tesla’s long-range Semi truck, offering one of the most vivid descriptions to date:
“It’s like driving an office building.”
The comparison may seem quirky—office buildings evoke images of immobility rather than motion—but it aptly conveys the experience of commanding a massive 23,000-pound Class 8 electric truck that delivers sports-car acceleration.
Lenotested the production-spec Long Range model, which is rated for up to 500 miles of range. He was visibly impressed by its performance, noting how the enormous vehicle moves with surprising urgency.
“It’s as fast as a Tesla, but it’s like driving an office building,” he remarked. “It’s this huge thing that moves like right now. You go 500 miles. You get 60% charge in 30 minutes. You’re saving on fuel costs. It seems quite good.”

The reaction highlights the cognitive dissonance at the core of the Tesla Semi. Traditional diesel semi-trucks are slow, noisy, and expensive to run. The Semi rewrites the rules with instant torque from its tri-motor electric powertrain, producing up to 800 kW.
Despite its size, the truck feels agile thanks to full electric steering assist, upgraded actuators borrowed from the Cybertruck, and a 48-volt electrical architecture that improves responsiveness and efficiency.
Tesla reports real-world energy consumption below 1.7 kWh per mile for the Long Range version. Megacharger stations can deliver a 60% charge in roughly 30 minutes, making the truck suitable for long-haul operations.
Additional features include an electric Power Take-Off (ePTO) capable of 25 kW for trailer refrigeration or other equipment, and a driver-focused cab with a central seating position for optimal visibility and a quiet, high-tech interior.
Fleet operators stand to benefit significantly from the economics. Diesel trucks often cost nearly one dollar per mile when including fuel, maintenance, and downtime.
Tesla projects the Semi can reduce operating costs to as low as 15 cents per mile through cheaper electricity, regenerative braking that minimizes brake wear, and reduced service requirements. While early deployments, like Pepsi’s, focused on shorter routes, the 500-mile variant targets cross-country applications.
Obstacles remain. A fully loaded tractor-trailer can reach 80,000 pounds, which reduces real-world range compared to the unloaded test conditions. Building out a nationwide Megacharger network will be essential for broader adoption. The Semi also carries a higher upfront price than conventional diesels, though total cost of ownership and available incentives frequently tip the scales in its favor over time.
Tesla Semi hauls fresh Cybercab batch as Robotaxi era takes hold
Leno’s “office building” description resonates because it captures the unexpected thrill of piloting something so large yet so capable. As the trucking industry faces pressure to cut emissions and control rising fuel expenses, the Semi offers a compelling alternative that excels in performance, comfort, and efficiency.
Coming from a man who has driven everything from vintage classics to modern hypercars, Leno’s genuine enthusiasm adds weight to the verdict.
The Tesla Semi is emerging as more than an experimental EV—it represents a practical vision for the future of heavy-duty transport where massive rigs accelerate instantly, and the numbers finally make sense. If fleet results continue to validate the claims, the era of diesel dominance could be drawing to a close.

Tesla expands its mass-market color palette in the U.S.
Delivering a fresh splash of color to its lineup, Tesla is giving U.S. buyers two stunning new blue options that are already turning heads.
Tesla has expanded the color palette it offers on its mass market vehicles in the United States, giving buyers of the Model 3 and Model Y a few additional options than before.
Delivering a fresh splash of color to its lineup, Tesla is giving U.S. buyers two stunning new blue options that are already turning heads. Starting on May 8, the automaker updated its North American configurator to introduce Marine Blue on Model Y Premium trims and Frost Blue exclusively on the Model 3 Performance.

The move replaces the long-running Deep Blue Metallic, a staple for over eight years, and brings previously exclusive shades stateside.
Marine Blue, a deep, rich oceanic hue formerly limited to Europe and Asia-Pacific markets, is now available on Model 3 and Model Y RWD and Long Range AWD Premium variants. Priced at a $1,000 upgrade—standard for Tesla’s premium paints—it delivers a sophisticated, metallic finish that shifts beautifully under light.

Tesla North America highlighted the change directly in an official post, confirming Marine Blue as the new flagship blue for non-Performance models.
Frost Blue, on the other hand, is the real crowd-pleaser for enthusiasts. Previously reserved for the flagship Model S and Model X, this lighter, icy metallic shade is now offered at no extra cost on Model 3 Performance and Model Y Performance trims.

Performance buyers effectively get a premium color included in the base price, a smart perk that Tesla has extended to higher-end variants across the board. Early in-person sightings and configurator renders show Frost Blue’s cool, modern vibe popping against the cars’ sleek lines, especially with black wheels and red brake calipers.
The timing couldn’t be better. With Tesla pushing refreshed Model 3 and Model Y refreshes amid growing competition, these updates add visual excitement without major redesigns.
Deep Blue Metallic orders are being transitioned to the new shades, according to customer reports and Tesla communications. In the U.S., Puerto Rico, and Mexico, the options are live now; Canada sees limited Frost Blue availability on the Model 3 Performance.
Tesla’s color strategy continues to evolve, borrowing from higher-end models to refresh mass-market EVs. Now that we bid farewell to the Model S and Model X, some of their colors might be available on the more widely available Model 3 and Model Y.

Tesla Semi’s official battery capacity leaked by California regulators
A California regulatory filing just confirmed the exact battery size inside each Tesla Semi variant.
A regulatory filing published by the California Air Resources Board in April 2026 has put official numbers on what Tesla Semi owners and fleet buyers have long wanted confirmed: the exact battery capacities of both the Long Range and Standard Range Semi truck variants. CARB is California’s independent air quality regulator, and it certifies zero-emission powertrains before they can be sold or operated in the state. When a manufacturer submits a vehicle for certification, the resulting executive order becomes a public document, making it one of the most reliable sources for confirmed production specs on any EV.
The document lists two certified powertrain configurations. The Long Range Semi carries a usable battery capacity of 822 kWh, while the Standard Range version comes in at 548 kWh. Both use lithium-ion NCMA chemistry and share the same peak and steady-state motor output ratings of 800 kW and 525 kW respectively. Cross-referencing Tesla’s published efficiency figure of approximately 1.7 kWh per mile under full load, the 822 kWh pack supports roughly 480 miles of real-world range, which aligns closely with Tesla’s advertised 500-mile figure for the Long Range trim. The 548 kWh Standard Range pack works out to approximately 320 miles, again consistent with Tesla’s stated 325-mile target.
Here is a direct comparison of the two versions based on the CARB filing and published specs:
| Tesla Semi Spec | Long Range | Standard Range |
| Battery Capacity | 822 kWh | 548 kWh |
| Battery Chemistry | NCMA Li-Ion | NCMA Li-Ion |
| Peak Motor Power | 800 kW | 525 kW |
| Estimated Range | ~500 miles | ~325 miles |
| Efficiency | ~1.7 kWh/mile | ~1.7 kWh/mile |
| Est. Price | ~$290,000 | ~$260,000 |
| GVW Rating | 82,000 lbs | 82,000 lbs |
The timing of this certification is not incidental. On April 29, 2026, Semi Programme Director Dan Priestley confirmed on X that high-volume production is now ramping at Tesla’s dedicated 1.7-million-square-foot facility in Sparks, Nevada. A key advantage of the Nevada location is vertical integration: the 4680 battery cells powering the Semi are manufactured in the same complex, eliminating the supply chain bottleneck that had delayed the program for years.
Tesla’s long-term goal is to reach a production capacity of 50,000 trucks annually at the Nevada factory, which would represent roughly 20 percent of the entire North American Class 8 market. With CARB certification now in hand and the production line running, the regulatory and manufacturing groundwork for that target is in place.
