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.

Tesla Cybercab spotted with interesting charging solution, stimulating discussion
The port is located in the rear of the vehicle and features a manual door and latch for plug-in, and the video shows an employee connecting to a Tesla Supercharger.
Tesla Cybercab units are being tested publicly on roads throughout various areas of the United States, and a recent sighting of the vehicle’s charging port has certainly stimulated some discussions throughout the community.
The Cybercab is geared toward being a fully-autonomous vehicle, void of a steering wheel or pedals, only operating with the use of the Full Self-Driving suite. Everything from the driving itself to the charging to the cleaning is intended to be operated autonomously.
But a recent sighting of the vehicle has incited some speculation as to whether the vehicle might have some manual features, which would make sense, but let’s take a look:
🚨 Tesla Cybercab charging port is in the rear of the vehicle!
Here’s a great look at plugging it in!!

The port is located in the rear of the vehicle and features a manual door and latch for plug-in, and the video shows an employee connecting to a Tesla Supercharger.
Now, it is important to remember these are prototype vehicles, and not the final product. Additionally, Tesla has said it plans to introduce wireless induction charging in the future, but it is not currently available, so these units need to have some ability to charge.
However, there are some arguments for a charging system like this, especially as the operation of the Cybercab begins after production starts, which is scheduled for April.
Wireless for Operation, Wired for Downtime
It seems ideal to use induction charging when the Cybercab is in operation. As it is for most Tesla owners taking roadtrips, Supercharging stops are only a few minutes long for the most part.
The Cybercab would benefit from more frequent Supercharging stops in between rides while it is operating a ride-sharing program.
Tesla wireless charging patent revealed ahead of Robotaxi unveiling event
However, when the vehicle rolls back to its hub for cleaning and maintenance, standard charging, where it is plugged into a charger of some kind, seems more ideal.
In the 45-minutes that the car is being cleaned and is having maintenance, it could be fully charged and ready for another full shift of rides, grabbing a few miles of range with induction charging when it’s out and about.
Induction Charging Challenges
Induction charging is still something that presents many challenges for companies that use it for anything, including things as trivial as charging cell phones.
While it is convenient, a lot of the charge is lost during heat transfer, which is something that is common with wireless charging solutions. Even in Teslas, the wireless charging mat present in its vehicles has been a common complaint among owners, so much so that the company recently included a feature to turn them off.
Production Timing and Potential Challenges
With Tesla planning to begin Cybercab production in April, the real challenge with the induction charging is whether the company can develop an effective wireless apparatus in that short time frame.
It has been in development for several years, but solving the issue with heat and energy loss is something that is not an easy task.
In the short-term, Tesla could utilize this port for normal Supercharging operation on the Cybercab. Eventually, it could be phased out as induction charging proves to be a more effective and convenient option.

Tesla confirms that it finally solved its 4680 battery’s dry cathode process
The suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.
Tesla has confirmed that it is now producing both the anode and cathode of its 4680 battery cells using a dry-electrode process, marking a key breakthrough in a technology the company has been working to industrialize for years.
The update, disclosed in Tesla’s Q4 and FY 2025 update letter, suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.
Dry cathode 4680 cells
In its Q4 and FY 2025 update letter, Tesla stated that it is now producing 4680 cells whose anode and cathode were produced during the dry electrode process. The confirmation addresses long-standing questions around whether Tesla could bring its dry cathode process into sustained production.
The disclosure was highlighted on X by Bonne Eggleston, Tesla’s Vice President of 4680 batteries, who wrote that “both electrodes use our dry process.”
Tesla first introduced the dry-electrode concept during its Battery Day presentation in 2020, pitching it as a way to simplify production, reduce factory footprint, lower costs, and improve energy density. While Tesla has been producing 4680 cells for some time, the company had previously relied on more conventional approaches for parts of the process, leading to questions about whether a full dry-electrode process could even be achieved.
4680 packs for Model Y
Tesla also revealed in its Q4 and FY 2025 Update Letter that it has begun producing battery packs for certain Model Y vehicles using its in-house 4680 cells. As per Tesla:
“We have begun to produce battery packs for certain Model Ys with our 4680 cells, unlocking an additional vector of supply to help navigate increasingly complex supply chain challenges caused by trade barriers and tariff risks.”
The timing is notable. With Tesla preparing to wind down Model S and Model X production, the Model Y and Model 3 are expected to account for an even larger share of the company’s vehicle output. Ensuring that the Model Y can be equipped with domestically produced 4680 battery packs gives Tesla greater flexibility to maintain production volumes in the United States, even as global battery supply chains face increasing complexity.

Tesla Giga Texas to feature massive Optimus V4 production line
This suggests that while the first Optimus line will be set up in the Fremont Factory, the real ramp of Optimus’ production will happen in Giga Texas.
Tesla will build Optimus 4 in Giga Texas, and its production line will be massive. This was, at least, as per recent comments by CEO Elon Musk on social media platform X.
Optimus 4 production
In response to a post on X which expressed surprise that Optimus will be produced in California, Musk stated that “Optimus 4 will be built in Texas at much higher volume.” This suggests that while the first Optimus line will be set up in the Fremont Factory, and while the line itself will be capable of producing 1 million humanoid robots per year, the real ramp of Optimus’ production will happen in Giga Texas.
This was not the first time that Elon Musk shared his plans for Optimus’ production at Gigafactory Texas. During the 2025 Annual Shareholder Meeting, he stated that Giga Texas’ Optimus line will produce 10 million units of the humanoid robot per year. He did not, however, state at the time that Giga Texas would produce Optimus V4.
“So we’re going to launch on the fastest production ramp of any product of any large complex manufactured product ever, starting with building a one-million-unit production line in Fremont. And that’s Line one. And then a ten million unit per year production line here,” Musk stated.
How big Optimus could become
During Tesla’s Q4 and FY 2025 earnings call, Musk offered additional context on the potential of Optimus. While he stated that the ramp of Optimus’ production will be deliberate at first, the humanoid robot itself will have the potential to change the world.
“Optimus really will be a general-purpose robot that can learn by observing human behavior. You can demonstrate a task or verbally describe a task or show it a task. Even show it a video, it will be able to do that task. It’s going to be a very capable robot. I think long-term Optimus will have a very significant impact on the US GDP.
“It will actually move the needle on US GDP significantly. In conclusion, there are still many who doubt our ambitions for creating amazing abundance. We are confident it can be done, and we are making the right moves technologically to ensure that it does. Tesla, Inc. has never been a company to shy away from solving the hardest problems,” Musk stated.
