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.

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.

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.

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.

SpaceX set to launch astronauts and a classified Falcon Heavy mission on the same day

SpaceX plans three launches Thursday, including Crew-13 astronauts and Falcon Heavy’s first classified NRO mission.

SpaceX is lining up one of the busiest single days in its history, and the company offered a preview on Wednesday morning with a simple post on X: “Sunrise at pad 40.” The video and photos show Falcon 9 standing at Space Launch Complex 40 at Cape Canaveral, roughly a day before it is scheduled to carry four astronauts to the International Space Station.

That launch is only the first of three SpaceX missions planned for Thursday, October 1, across both coasts.

Crew-13 is targeting liftoff at 11:10 a.m. ET, with a backup opportunity Friday at 10:47 a.m. ET. NASA astronaut Jessica Watkins will command the mission, with NASA’s Luke Delaney as pilot and Canadian Space Agency astronaut Joshua Kutryk and Roscosmos cosmonaut Sergey Teteryatnikov serving as mission specialists. According to NASA, Dragon is set to dock with the forward port of the station’s Harmony module around 8 p.m. ET, less than nine hours after launch. Watkins is the only member of the crew who has flown before, and Kutryk will become the first Canadian to reach orbit through NASA’s Commercial Crew Program.

The Falcon 9 booster is flying for the third time after supporting Crew-12 and a Starlink mission, and it will attempt a landing at Landing Zone 40 beside the pad. That site made its debut in February when the Crew-12 booster touched down there, as Teslarati reported at the time. Crew-13 will relieve the Crew-12 astronauts, who have been aboard the station since the middle of February.

On the West Coast, another Falcon 9 is scheduled to lift off from Vandenberg Space Force Base in a window running from 2:18 to 3:16 p.m. ET, a flight NASASpaceflight lists as a Transporter rideshare mission.

The day is set to close at 11:53 p.m. ET, when Falcon Heavy launches from Launch Complex 39A with NROL-97, the first National Reconnaissance Office payload ever to fly on the rocket. SpaceX rolled the vehicle out to the pad Tuesday night. Its two side boosters, which previously flew GOES-U, ViaSat-3 F3 and NASA’s Roman Space Telescope, will return to Landing Zones 1 and 2, while a new center core will be expended in the Atlantic. The Roman launch took place on August 30, so NROL-97 will come barely a month later as Falcon Heavy’s third flight of 2026 and 14th overall.

NASA taps SpaceX to launch the telescope that could unlock new worlds

If all three Florida boosters land as planned, it would be the first time the Space Coast has seen landings at LZ-40, LZ-1 and LZ-2 on the same day, according to the Orlando Sentinel, which has warned residents in Brevard, Orange and Volusia counties that more than one sonic boom is possible.

The schedule arrives just three days after Starship reached orbit for the first time on Flight 14 from Starbase, Texas, deploying 26 Starlink V3 satellites. If Thursday’s missions stay on time, SpaceX will have flown Starship, Falcon 9 and Falcon Heavy from four different pads in about four days.

Crew-13 is also the start of a longer run for Dragon. NASA recently added Crew-15, Crew-16 and Crew-17 to SpaceX’s contract in a $946 million modification, keeping Dragon as the agency’s only operational ride to the station while Boeing’s Starliner remains grounded.

Tesla Cybercab and Semi have more in common than you might think

Published

Although the two vehicles are built for completely different use cases, Tesla utilized engineering expertise while developing both the Cybercab and Semi to build a thermal architecture that would fit both vehicles. Of course, with some slight revisions.

The development was noted by Lars Moravy and Dan Priestley last week at Tesla’s Semi Handover event in Sparks, Nevada, where the company showed off its dedicated production facility for the Class 8 truck.

Tesla’s decision to develop one thermal architecture for both the Cybercab and Semi is one of the more revealing engineering choices in the company’s 2026 lineup:

“We designed it at the same time we designed the Cybercab and we said okay we’re going to take our most efficient vehicle and our biggest vehicle and we’re going to take one thermal system and make it work for both.”

Core parts, meaning the compressor, pumps, and heat exchangers, are shared, with only modest changes to cooling-loop sizing and a larger radiator on the truck. The result, they said, is a compressor and thermal stack already proven across millions of miles, delivering “reliability from day one.”

Priestley also highlighted a practical payoff of the indirect design:

“There’s no AC lines, there’s no refrigerant lines…It comes from the factory fully charged, sealed with refrigerant, and it just exchanges coolant. It doesn’t actually run refrigerant up to the front of the vehicle.”

This eliminates potentially leak-prone plumbing that would otherwise require hands-on service, reducing overall uptime and potentially cutting into business margins. The megamanifold runs cabin HVAC and every powertrain heating and cooling loop at once, recapturing waste heat from motors and the battery instead of dumping it the way a diesel engine does.

The approach is just the latest chapter in a continuing story of stretching thermal solutions across wildly different vehicles. Model Y’s Octovalve evolved into the Super Manifold used on Cybertruck, and later Model S/X refreshes. Cybercab then introduced Supermanifold V3, which Tesla says is 80 percent automated to build and 38 percent more efficient than typical automotive thermal systems.

Tesla has done the same with the 4680 cells, both being utilized in the Cybertruck and Semi, and with heat-pump compressors that Priestley noted were already common across the passenger-car fleet.

Concurrent development of crucial vehicle elements buys scale and reliability that a truck-only thermal system could not match. High-volume passenger car parts are cheaper and more accessible, which can give fleets a sealed, low-maintenance loop of operation from their first day of operation.

For owners and operators, that translates into less energy spent on cabin heat in the colder months, fewer refrigerant-related repairs, and a thermal architecture already stress-tested at passenger-car volumes before the first high-volume Semi left the lines in Nevada.

Elon Musk weather update tips Tesla Roadster speculation into Plaid Mode

Published

on

Tesla CEO Elon Musk certainly tipped off some details of the Tesla Roadster event with a broadening of information regarding the company’s decision to delay the unveiling for two weeks.

For years, people have speculated about what the Roadster will be capable of. While there have been plenty of things said about what it *could* do, we have not seen or been told by Tesla what it will actually be capable of.

However, over the past few days, Tesla’s weather updates have truly pushed the speculation into Plaid Mode, basically all but confirming the car will have some sort of aerial capability — whether that would be hovering or fully flying remains to be seen — but it definitely seems that it will be able to leave the ground intentionally.

“Because this event can only be held outdoors…”

Tesla posted on Monday that it would delay the Roadster event until October 15, and it indicated that it had to do this because the event “can only be held outdoors.”

With the potential SpaceX collaboration to develop cold-gas thrusters that will help the vehicle go airborne, doing this indoors is probably not a safe, or even plausible, possibility.

FAA Airspace Restriction

The FAA gave Tesla a Temporary Flight Restriction (TFR) for 10,000 feet above ground level, much higher than the typical 2,000-foot restrictions that are usually placed at SpaceX’s McGregor, Texas site.

Tesla Roadster event requires restricted airspace, and the FAA obliges

Some have said that this massive increase is due to Tesla’s need to restrict unauthorized drone use for spying on the event.

Elon Admits High Winds

“Due to high winds, the new Roadster demo is postponed by 2 weeks,” Musk said in a post on X yesterday.

A reply reading, “What’s strong wind got to do with a car demo with four grounded wheels?” was directly below Musk’s post, satirically and sarcastically probing for more details.

All signs are pointing toward an aerial demonstration for the Roadster.
