SpaceX Falcon 9 fires up ahead of second to last 2019 launch and landing
SpaceX has successfully static fired a Falcon 9’s booster engines ahead of its second to last launch and landing of 2019, on track to make December the company’s busiest month of the year.
About a month after successfully lofting 60 Starlink satellites and 11 days after sending Cargo Dragon on its way to the ISS for CRS-19, SpaceX has two more launch scheduled in 2019: Kacific-1 no earlier than (NET) December 16th and Starlink-2 NET December 30th.
For SpaceX, the turn of the decade will mark the end of an historic year – let alone decade – of milestones for the intrepid commercial space company, including achievements like’s Crew Dragon flawless orbital launch debut, the fourth flight of a refurbished Falcon 9 booster, the first-ever reuse of a flight-proven payload fairing, and a duo of spectacular Starhopper flight tests to name just a few.
First up, SpaceX will fly twice-flown Falcon 9 booster B1056.3 for the third time. B1056.3 previously supported CRS-17 and CRS-18, back to back Cargo Dragon space station resupply missions for NASA. Currently targeting a Monday, December 16th launch, SpaceX is set to place the jointly-owned JCSAT-18/Kacific-1 broadband communication satellite for Japan’s Sky Perfect JSAT Corp. and Singapore’s self-proclaimed “next-generation broadband satellite operator”, Kacific Broadband Satellites.
According to a Kacific, after deploying from Falcon 9 and circularizing into a geostationary orbit some 22,000 miles (36,000km) over the Asia-Pacific region, the JCSAT-18/Kaficic-1 satellite “will stream broadband to 25 nations in South East Asia and the Pacific Islands via 56 spot beams.” All told, the satellite will offer a maximum bandwidth of 70 gigabits per second (Gbps) with each spot beam serving up to 1.25 Gbps.
Kacific was founded in 2013 by CEO Christian Patouraux to provide desperately needed communication services to the Asia Pacific region, “where high prices and unsuitable technology were prohibiting access.” Kacific looks to “provide high speed, affordable and accessible internet to extra-urban, rural, and remote users” with Kacific-1, the company’s first (partially) dedicated satellite.
Ahead of Monday’s launch attempt, the JCSAT-18/Kacific-1 satellite was fully encapsulated inside Falcon 9’s payload fairing, both halves of which SpaceX will try to catch with recovery vessels GO Ms. Tree and GO Ms. Chief in what will be the company’s first simultaneous catch attempt ever. Meanwhile, B1056 has its own recovery attempt penciled in and drone ship Of Course I Still Love You (OCISLY) departed Port Canaveral on December 12th, headed ~650 km (400 mi) downrange. OCISLY arrived at its recovery zone earlier today, as did Ms. Tree and Ms. Chief, now stationed about 140 km (90 mi) further East.
As per usual, Falcon 9 B1056.3 and its expendable upper stage performed a wet dress rehearsal (WDR) and static fire, identical to launch operations minus the rocket actually lifting off. The Kacific-1 mission’s December 16th launch trajectory allows for an 88-minute window from 7:10 pm – 8:38 pm EST (0010-0138 UTC, December 17) and weather forecasts are currently 90% go.
As mentioned, twin fairing recovery vessels GO Ms. Tree and GO Ms. Chief departed Port Canaveral on December 13th in a bid to attempt their first simultaneous Falcon fairing recovery, meaning that each ship will attempt to catch one parasailing fairing half. This mission is technically the second time both ships have port left together for a recovery, but their first whole-airing catch attempt was called off before it could start due to rough seas and high winds in the Atlantic Ocean. Prior to being rechristened Ms. Tree, Mr. Steven suffered severe damage during a planned February 2019 catch attempt, losing its net and two of four arms after the ship was caught in high seas.
Following Kacific-1, SpaceX’s final launch of 2019 – barring delays – will likely be the company’s second dedicated Starlink v1.0 mission, a 60-satellite payload that will almost certainly make SpaceX the world’s largest commercial satellite operator. Starlink-2 is scheduled to launch NET December 30th.
SpaceX will stream Falcon 9’s Kacific-1 launch and landing and the webcast will kick off some 15 minutes before liftoff, NET 6:55 pm ET (23:55 UTC), December 16th.

A Tesla Semi caught fire in Hayward, California, which caused both directions of traffic to shut down for hours before being completely reopened early on Wednesday, the California Highway Patrol said.
The fire occurred just after 5:30 local time in Hayward on Tuesday, as the Semi caught fire in the southbound lanes of I-880 before CHP officials made the decision to shut down both lanes of traffic due to potential risks from hazardous chemical smoke.
There were no injuries reported.

The cause of the fire is currently unknown, as neither Tesla nor the CHP have not determined a cause.
However, some images taken before the Semi was completely destroyed by the fire seem to indicate this might have been an older unit, as it appears to be one of the designs that Tesla shipped as part of its pilot program, before revising it and starting mass production just a month ago.
@Tslachan From on of the videos looks like it’s an old Semi (not the refresh version that recently started production) https://t.co/KzwmR2kXow

At the time of publication, CHP had not returned our request for a comment for additional details, including the Semi involved and any potential collaboration on an investigation between the CHP and Tesla. We will update this story when we hear back from them.
The southbound lanes were reopened at 3:30 a.m. on Wednesday, with the northbound lanes opening last night a few hours after the fire began. The CHP did state that the lithium batteries were “incredibly difficult to extinguish,” according to NBC Bay Area.
The truck’s driver said that the Semi caught fire, but he did not have an explanation.

Tesla’s launch of the “Emergency Drive Away” function a few months back offered owners a safe option to evacuate an area if they were in reasonable danger. The function finally got its first use in the real world, but it appears it was by mistake.
A video shared by u/Joshalander in the r/TeslaLounge subreddit recorded the instance from his vehicle and said the incident took place in Austin this past weekend during the city’s F1 Race.
“Was charging around 6 AM this past Sunday in Austin before heading to the F1 race and heard a pop. Looked over and saw the new emergency drive-away feature in action. Genuinely felt bad for the dude when he got out and realized what happened, since he looked exhausted and only seemed to half-read the prompts.”
🚨 Here’s the first look at Tesla’s Emergency Drive Away function in action:
Apparently this driver accidentally enabled it and drove forward; you can see the Supercharger pull with the car.
Tesla said previously this would cost up to $25k if not used properly. https://t.co/B4qQRrsO6B

Emergency Drive Away unlatches the Supercharger connector from the vehicle, but still causes damage to both the car and the Supercharger. Tesla has said that it will cost up to $25,000 in repairs to have everything fixed back to normal.
Additionally, the company said that if it were not used in an emergency situation, the driver of the vehicle who activated the Emergency Drive Away feature would be responsible for all repair costs.
Tesla constitutes the following situations as reasonable justifications for activating the feature:
- You face an immediate threat to your life or personal safety.
- You must leave the area immediately.
- Exiting the vehicle is unsafe.
- Unplugging the charge connector would unreasonably delay your departure or expose you to a risk to your personal safety.
After using the feature, Tesla requires the driver to schedule Service so the car can be inspected.

Tesla’s Cybercab battery design could make robotaxis even cheaper
Tesla built the Cybercab’s battery pack with spare room for a future switch to LFP.
Tesla built the Cybercab’s battery pack with empty space inside it on purpose, and the reason points to a cheaper robotaxi down the road.
Robert Sumpf, Tesla’s director of mechanical design engineering for battery modules and packs, said the extra room beside and beneath the Cybercab’s modules was left there so the company can move to lithium iron phosphate cells later. “So, we protected this pack to go to an even lower energy dense chemistry as we scale and need to bring LFP into the platform,” Sumpf said in a Cybercab deep dive with Munro Live.
The Cybercab runs on Tesla’s own 4680 cells with a nickel chemistry today. LFP cells store less energy for their size, so a straight swap would cut range. The reserved space lets Tesla add more LFP cells to make up the difference. In return, Tesla would get cells that cost less, run cooler and survive more charge cycles. LFP became the most used EV battery chemistry in the world last year.
Not all of that room was planned for a chemistry change. Lars Moravy, Tesla’s Vice President of Vehicle Engineering, said part of it exists because “we didn’t need as many batteries as we thought we did.” Tesla told Sandy Munro in early 2025 that it was targeting a Cybercab pack under 50 kWh with close to 300 miles of range.
The pack also breaks from the structural design Tesla used in some Model Y and Cybertruck builds. Instead of potting hundreds of cells into one block, the Cybercab uses four separate, individually sealed modules, so a bad module can be replaced without scrapping the whole pack. Sumpf was blunt about the older approach, giving the Model Y structural battery “a grade D” because it was hard to build and nearly impossible to repair. He estimated a fully structural pack gains about 10% more cell volume, but said “the issue is the service cost.”
That cost matters more for a car that rarely sits parked. Cybercab chief engineer Eric Earley said replacing an entire pack “before half a million miles is a killer on cost,” which is why remanufacturing and serviceability were built into the design from the start.
The same Munro Live tour produced Moravy’s admission that the Cybercab line at Giga Texas is now outpacing Robotaxi deployments, along with a look at the robotaxi’s unorthodox paint process. Tesla is aiming to deliver the first Cybercabs to outside customers by the end of 2026, though Elon Musk has said the vast majority will stay owned by Tesla and run as a transport service.
Sumpf did not give a date for an LFP version, name a cell supplier or say how a chemistry change would affect range. For now, the 4680 cars keep piling up: Texas DMV records from Tuesday list 544 Cybercabs authorized for Tesla’s Robotaxi fleet, more than the 507 Model Ys on the same roster for the first time.
