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 is improving Giga Berlin’s free “Giga Train” service for employees
With this initiative, Tesla aims to boost the number of Gigafactory Berlin employees commuting by rail while keeping the shuttle free for all riders.
Tesla will expand its factory shuttle service in Germany beginning January 4, adding direct rail trips from Berlin Ostbahnhof to Giga Berlin-Brandenburg in Grünheide.
With this initiative, Tesla aims to boost the number of Gigafactory Berlin employees commuting by rail while keeping the shuttle free for all riders.
New shuttle route
As noted in a report from rbb24, the updated service, which will start January 4, will run between the Berlin Ostbahnhof East Station and the Erkner Station at the Gigafactory Berlin complex. Tesla stated that the timetable mirrors shift changes for the facility’s employees, and similar to before, the service will be completely free. The train will offer six direct trips per day as well.
“The service includes six daily trips, which also cover our shift times. The trains will run between Berlin Ostbahnhof (with a stop at Ostkreuz) and Erkner station to the Gigafactory,” Tesla Germany stated.
Even with construction continuing at Fangschleuse and Köpenick stations, the company said the route has been optimized to maintain a predictable 35-minute travel time. The update follows earlier phases of Tesla’s “Giga Train” program, which initially connected Erkner to the factory grounds before expanding to Berlin-Lichtenberg.
-->Tesla pushes for majority rail commuting
Tesla began production at Grünheide in March 2022, and the factory’s workforce has since grown to around 11,500 employees, with an estimated 60% commuting from Berlin. The facility produces the Model Y, Tesla’s best-selling vehicle, for both Germany and other territories.
The company has repeatedly emphasized its goal of having more than half its staff use public transportation rather than cars, positioning the shuttle as a key part of that initiative. In keeping with the factory’s sustainability focus, Tesla continues to allow even non-employees to ride the shuttle free of charge, making it a broader mobility option for the area.

Tesla Model 3 and Model Y dominate China’s real-world efficiency tests
The Tesla Model 3 posted 20.8 kWh/100 km while the Model Y followed closely at 21.8 kWh/100 km.
Tesla’s Model 3 and Model Y once again led the field in a new real-world energy-consumption test conducted by China’s Autohome, outperforming numerous rival electric vehicles in controlled conditions.
The results, which placed both Teslas in the top two spots, prompted Xiaomi CEO Lei Jun to acknowledge Tesla’s efficiency advantage while noting that his company’s vehicles will continue refining its own models to close the gap.
Tesla secures top efficiency results
Autohome’s evaluation placed all vehicles under identical conditions, such as a full 375-kg load, cabin temperature fixed at 24°C on automatic climate control, and a steady cruising speed of 120 km/h. In this environment, the Tesla Model 3 posted 20.8 kWh/100 km while the Model Y followed closely at 21.8 kWh/100 km, as noted in a Sina News report.
These figures positioned Tesla’s vehicles firmly at the top of the ranking and highlighted their continued leadership in long-range efficiency. The test also highlighted how drivetrain optimization, software management, and aerodynamic profiles remain key differentiators in high-speed, cold-weather scenarios where many electric cars struggle to maintain low consumption.
Xiaomi’s Lei Jun pledges to continue learning from Tesla
Following the results, Xiaomi CEO Lei Jun noted that the Xiaomi SU7 actually performed well overall but naturally consumed more energy due to its larger C-segment footprint and higher specification. He reiterated that factors such as size and weight contributed to the difference in real-world consumption compared to Tesla. Still, the executive noted that Xiaomi will continue to learn from the veteran EV maker.
“The Xiaomi SU7’s energy consumption performance is also very good; you can take a closer look. The fact that its test results are weaker than Tesla’s is partly due to objective reasons: the Xiaomi SU7 is a C-segment car, larger and with higher specifications, making it heavier and naturally increasing energy consumption. Of course, we will continue to learn from Tesla and further optimize its energy consumption performance!” Lei Jun wrote in a post on Weibo.
-->Lei Jun has repeatedly described Tesla as the global benchmark for EV efficiency, previously stating that Xiaomi may require three to five years to match its leadership. He has also been very supportive of FSD, even testing the system in the United States.

Elon Musk reveals what will make Optimus’ ridiculous production targets feasible
Musk recent post suggests that Tesla has a plan to attain Optimus’ production goals.
Elon Musk subtly teased Tesla’s strategy to achieve Optimus’ insane production volume targets. The CEO has shared his predictions about Optimus’ volume, and they are so ambitious that one would mistake them for science fiction.
Musk’s recent post on X, however, suggests that Tesla has a plan to attain Optimus’ production goals.
The highest volume product
Elon Musk has been pretty clear about the idea of Optimus being Tesla’s highest-volume product. During the Tesla 2025 Annual Shareholder Meeting, Musk stated that the humanoid robot will see “the fastest production ramp of any product of any large complex manufactured product ever,” starting with a one-million-per-year line at the Fremont Factory.
Following this, Musk stated that Giga Texas will receive a 10 million-per-year unit Optimus line. But even at this level, the Optimus ramp is just beginning, as the production of the humanoid robot will only accelerate from there. At some point, the CEO stated that a Mars location could even have a 100 million-unit-per-year production line, resulting in up to a billion Optimus robots being produced per year.
Self-replication is key
During the weekend, Musk posted a short message that hinted at Tesla’s Optimus strategy. “Optimus will be the Von Neumann probe,” the CEO wrote in his post. This short comment suggests that Tesla will not be relying on traditional production systems to make Optimus. The company probably won’t even hire humans to produce the humanoid robot at one point. Instead, Optimus robots could simply produce other Optimus robots, allowing them to self-replicate.
-->The Von Neumann is a hypothetical self-replicating spacecraft proposed by the mathematician and physicist John von Neumann in the 1940s–1950s. The hypothetical machine in the concept would be able to travel to a new star system or location, land, mine, and extract raw materials from planets, asteroids, and moons as needed, use those materials to manufacture copies of itself, and launch the new copies toward other star systems.
If Optimus could pull off this ambitious target, the humanoid robot would indeed be the highest volume product ever created. It could, as Musk predicted, really change the world.
