SpaceX, Rocket Lab, ULA all have rocket launches planned this weekend
The final weekend of August 2020 is shaping up to be an exciting one in the world of rocket launching. United Launch Alliance (ULA) looks to kick off weekend activities early on Saturday morning with the launch of its Delta IV Heavy rocket carrying a classified satellite payload for the National Reconnaissance Office at 2:04 am EDT (0604 UTC) from Cape Canaveral Air Force Station’s Space Launch Complex 37. Following a successful ULA launch, the weekend’s activity will kick into high gear. Even SpaceX founder and CEO, Elon Musk, agrees that this weekend could be “intense” as stated in a post to his Twitter account Friday, August 28.
Good chance something will slip, but, yeah, Sunday is intense— Elon Musk (@elonmusk) August 28, 2020
According to weather Launch Mission Execution Forecasts provided by the 45th Weather Squadron and confirmed via the company’s Twitter account, SpaceX aims to get two Falcon 9’s launched from the Florida coast just nine hours apart. The company also has a possible flight test of its Starship prototype vehicle on the books from Boca Chica, Texas this weekend. Rocket Lab looks to join in the launching activity with the return to flight mission of its Electron rocket following the wrap-up of its recent in-flight anomaly investigation.

SpaceX can only launch this weekend if ULA does too
As SpaceX and ULA both launch from what is referred to as the eastern range – the location of all launches originating from Cape Canaveral Air Force Station or Kennedy Space Center – only one launch provider can be supported at a time by the 45th Space Wing and 45th Weather Squadron which oversee eastern range operations.
As a part of the reservation process ahead of securing a launch date with the eastern range, each launch provider chooses a targeted launch date and secures a number of back-up launch opportunities should a delay occur.
In the case of ULA’s NROL-44 mission, a primary launch opportunity and two back-up opportunities – 24 hours and 48 hours after the initial launch attempt – have been identified. This means that should the Delta IV Heavy suffer another critical issue resulting in a delay during its Saturday, August 29 primary launch attempt, both of SpaceX’s Falcon 9 launch opportunities will be delayed as well.
ULA’s NROL-44 Delta IV Heavy carries a classified satellite payload for the National Reconnaissance Office, a national security division of the United States government. As such, the NROL-44 mission is a matter of national security and takes precedence over both SpaceX’s internal Starlink mission and SAOCOM-1B payload for customer Comisión Nacional de Actividades Espaciales, Argentina’s national space agency.
If the ULA NROL-44 mission is delayed through both back-up launch opportunities SpaceX, presumably, would have to wait until no earlier than Tuesday, September 1 to launch a Falcon 9.
Rocket Lab “I Can’t Believe It’s Not Optical”
While SpaceX will have to wait for ULA’s Delta IV Heavy to clear its pad before attempting either of the planned Falcon 9 launches, Rocket Lab will attempt the return to flight mission of its Electron rocket – the fourteenth flight overall – regardless (weather permitting).
The launch attempt initially scheduled for 11:04pm ET (0304 UTC) Friday, August 28 was rescheduled due to high winds and heavy cloud cover over Launch Complex-1A in Mahia, New Zealand. The next available launch attempt at 11:05 pm ET Sunday, August 30 (0305 UTC Monday, August 31) lines up for Electron to take off just four hours after SpaceX’s SAOCOM-1B mission.
Launch Update: Ground winds remain high at LC-1 tomorrow, so we're now targeting no earlier than Aug 31 UTC for the #ICantBelieveItsNotOptical mission. 🚀🛰️

Following an in-flight anomaly during Electron’s thirteenth mission in July, Rocket Lab was forced to stand down from active launching status to complete a full investigation into the incident. In about a month’s time, Rocket Lab was able to track down and remedy an overheating issue with a single electrical connection on Electron’s second stage.
After receiving clearance from the Federal Aviation Administration to resume operational launches, Rocket Lab has announced that Electron’s fourteenth flight -nicknamed “I Can’t Believe It’s Not Optical” – will be a dedicated mission for Capella Space, a California-based company that utilizes Earth observation data to provide information services.
According to a statement provided by Rocket Lab, the satellite payload called “Sequoia” is “a single 100 kg class microsatellite which will be the first publicly available satellite in the company’s commercial Synthetic Aperture Radar (SAR) constellation.”
A big goal of Rocket Lab’s is to join competitor SpaceX in a class of launchers that regularly recovers and reuses orbital-class boosters. Rocket Lab intends to catch an Electron first-stage booster in-flight once it has been dispensed by catching the falling booster’s parachute canopy with a grappling hook secured to a helicopter.
However, the company has stated that a full-scale demonstration of this effort is targeted for no earlier than the seventeenth mission of Electron currently slated to occur in Fall 2020.
If all proceeds as planned, this weekend could end up as a launchfest of rockets and spaceship prototypes. At the time of publishing, all is proceeding as expected for ULA’s Delta IV Heavy launch attempt and the weather looks good on Saturday, August 29.
ULA has confirmed that the previous issues that caused a launch attempt delay have all been cleared and weather outlook remains at an 80% chance of favorable launching conditions.
The launch attempt will be streamed live and is expected to begin at 1:43 am EDT (0543 UTC) on the company’s website or viewed below.

Investor's Corner
Tesla has a Cybercab problem nobody saw coming
Tesla’s Cybercab line now builds robotaxis faster than Tesla can deploy them, Lars Moravy says.
Tesla’s Cybercab line in Texas can now build the two seat robotaxi faster than the company can put it into service, according to Lars Moravy, Tesla’s Vice President of Vehicle Engineering. “We don’t run every day because the line can run so fast. It’s currently outpacing our deployments,” Moravy said in a new Cybercab deep dive from Munro Live. “So, it’s a bit of a race right now. Who’s going to go faster? Right now the manufacturing line’s ahead.”
Tesla’s official Robotaxi account shared a Cybercab analysis video on X on Monday, calling it a “Cybercab engineering deep dive.” Moravy’s comments go further than what he told analysts on the Q3 earnings call last week, when he said the Cybercab line’s listed capacity of more than 125,000 units a year undersells what it can actually run.
The tour shows where that speed comes from. Tesla’s unboxed process splits the Cybercab into front, rear, side and center modules that are built and tested on their own before they meet on a short final line. That final line has just 25 fully automated stations, which Tesla’s team estimated is a fifth to a tenth of what a Model Y needs. The full line is about 78% automated, the framing line is already at 100%, and the layout uses roughly 50% less floor space per vehicle. The stated goal is “100% automation in 10 second cycle time,” or one finished Cybercab every 10 seconds.
Tesla also deleted the paint shop. Only the side modules are coated, and the exterior panels get their color inside the molding machine. Engineers said the car is designed to run at least 500,000 miles, which matters for a vehicle that will spend most of its day carrying riders.
The battery got the same treatment. The Cybercab uses an 88S6P pack of 4680 cells in a steel enclosure, a first for Tesla, with each module potted separately so a single failed module can be swapped instead of the whole pack. Wireless battery management boards replace a wiring harness, and new contactors are fast enough to drop the pyro fuse entirely. Tesla’s battery director graded the pack an A minus, compared with a D for the Model Y structural pack and a B minus for Cybertruck. Up front, the drive unit runs an 11:1 gear ratio versus roughly 9:1 on most Teslas, since the Cybercab does not need a high top speed.
Cybercab engineering deep dive — Robotaxi (@robotaxi) October 26, 2026
The deployment side is now the bottleneck Moravy described. Tesla had more than 50 Cybercabs working the Formula 1 weekend in Austin, and Texas records show 463 Cybercabs registered. Tesla said on its earnings call that Cybercab service will launch in Dallas next month, and Moravy said the company is aiming to get Cybercabs to customers by the end of 2026. Every unit built so far has gone into Tesla’s own fleet since the line moved into volume production in April.
Munro Live also asked when it could get a Cybercab to tear down. Tesla’s answer: “Not yet.”

How SpaceX Is raising Raptor’s sea-level thrust while holding engine mass steady
SpaceX’s Raptor engine family has steadily increased sea-level thrust while simultaneously reducing mass, turning iterative engineering gains into substantially higher performance for the Super Heavy booster. CEO Elon Musk shed more light on how powerful Raptor 4 will be, and it’s pretty crazy.
Raptor 1 delivered 185 metric tons of thrust at roughly 2,080 kilograms, while Raptor 2 raised that to 230 tons while cutting mass to about 1,630 kilograms. SpaceX data for Raptor 3 lists a target of 280 tons at 1,525 kilograms (with further reductions in associated vehicle hardware), while operational flight ratings have been cited near 250 tons.
This morning, Elon Musk stated that Raptor 4 is expected to reach 300 tons of sea-level thrust at roughly the same mass as Raptor 3. Across these versions, thrust has risen by more than 60 percent from the first engines while engine mass has fallen, producing a sharp improvement in thrust-to-weight ratio. This is a true testament to how great SpaceX engineering has been:
🚀 Elon says Raptor 4 will make 300 tons of thrust at sea level at roughly the same mass as Raptor 3.
How far Raptor has come:
Raptor 1: 185 tf, 2,080 kg
Raptor 2: 230 tf, 1,630 kg
Raptor 3: 250 tf, 1,525 kg
Raptor 4: 300 tf33 on Super Heavy = ~9,900 tf, nearly 3x Saturn V https://t.co/HQDswZhyvL

With 33 engines on SuperHeavy, the jump from earlier versions to a 300-ton Raptor 4 would produce roughly 9,900 metric tons of total liftoff thrust, nearly three times the Saturn V’s approximately 3,400 metric tons from its five F-1 engines.
This is not just a larger number on a data sheet, either, as sea-level thrust is the force available the moment the vehicle leaves the pad. This is when it is heaviest and still deep in Earth’s gravity well and dense atmosphere.
Higher levels of sea-level thrust directly improves the initial thrust-to-weight ratio of the full stack. A higher ratio produces faster acceleration off the pad, which shortens the time the rocket has to spend fighting gravity, and gravity losses during the first minute or two of the flight are a major drain on total available delta-v. Every second shaved off of that early climb preserves more propellant energy for reaching orbital velocity or for carrying extra payload.
Because Super Heavy’s engine count is constrained by vehicle diameter and packing density, increasing thrust per engine is the most straightforward way to raise total liftoff performance without redesigning the booster structure or design.
The same-mass target for Raptor 4 is equally important. Holding engine mass roughly constant while raising thrust improves the engine’s own thrust-to-weight ratio and reduces the structural and propellant mass fraction that must be carried solely to support the engines.
Earlier Raptor iterations also simplified or eliminated extensive vehicle-side hardware such as heat shields. These gains compound: more force for less installed mass leaves additional capacity for propellant, payload, or operational margins such as engine-out capability.
For Starship’s architecture, the practical effects are large. Greater liftoff thrust supports heavier vehicles, larger propellant loads, and higher payloads to low Earth orbit, figures SpaceX has targeted in the 100-plus-ton reusable range. That capacity underpins orbital refueling, lunar missions, and eventual Mars cargo and crew flights.
Continued growth in sea-level thrust therefore tightens the gap between theoretical rocket performance and the high flight rates and reusability needed to make large-scale space transport practical.

Tesla Assisted Driving expands to tenth EU country
Tesla has expanded its Tesla Assisted Driving (TAD) suite to its tenth European country, as Latvia joined a growing list of European Union member states authorizing the company’s advanced driver assistance technology.
Tesla Europe announced this morning that the system is now approved in Latvia, with a software rollout to begin soon.
The approval and rollout follow recognition of a provisional European type approval originally granted by the Netherlands’ RDW authority on April 10.
🚨 Latvia has just received approval for Tesla Full Self-Driving (Supervised)
This is the 10th country in the EU to gain approval:
1. Netherlands — 10 April 2026 (original RDW approval)
2. Lithuania — 20 May 2026
3. Estonia — 29 May 2026
4. Denmark — 9 June 2026
5. Belgium — 10 June 2026
6. Slovenia — 7 September 2026
7. Czechia — 21 September 2026
8. Croatia — 29 September 2026
9. Slovakia — 16 October 2026— TESLARATI (@Teslarati) October 26, 2026
Latvia’s Road Traffic Safety Directorate (CSDD) evaluated the Dutch documentation, coordinated with the other national authorities, and reviewed updates from Tesla. These included tightened limits on speed offsets, automatic resets of any manual speed adjustments after each trip, and stronger driver monitoring.
In Europe, the feature is marketed as Tesla Assisted Driving after a recent rule change that labeled the name “Full Self-Driving” as misleading.
The system remains an SAE Level 2 driver assistance tool, not unsupervised autonomy. It can control speed, steering, braking, lane changes, and intersections while following a navigation route. Drivers need not keep their hands on the wheel at all times, yet they must continuously monitor the road and be prepared to intervene immediately.
The sequence of EU recognitions began with the Netherlands in April and continued through Lithuania, Estonia, Denmark, Belgium, Slovenia, Czechia, Croatia, and Slovakia. Most have relied on mutual recognition of the single Dutch provisional approval rather than independent national testing.
These national clearances do not yet constitute bloc-wide authorization. An EU-wide decision requires a qualified majority in the Technical Committee on Motor Vehicles: at least 15 of 27 member states representing 65 percent of the EU population. Larger markets, like Germany, France, and Italy, remain under review, and a vote is expected this December.
However, for Latvian Tesla owners with compatible vehicles and software, the imminent rollout expands access to the supervised system while underscoring that attentive human oversight remains essential.
