SpaceX Falcon 9 rocket tests engines for first launch and landing of the new decade

SpaceX has successfully fired up a Falcon 9 rocket for the first time in 2020, setting the company up for the first of potentially dozens of Starlink launches over the next 12 months.

On the afternoon of January 4th, SpaceX loaded Falcon 9 with hundreds of tons of liquid oxygen, refined kerosene (RP-1), nitrogen, and helium and ultimately ignited all nine of the booster’s Merlin 1D engines, briefly producing some 7600 kN (1.7 million lbf) of thrust in a routine test known as a wet dress rehearsal (WDR) and static fire. As is tradition, SpaceX confirmed that the test looked successful just a handful of minutes after it was completed and verified that the rocket is now scheduled to launch 60 new Starlink satellites as early as 9:19 pm ET, January 6th (02:19 UTC, Jan 7).

Set to lift off from its LC-40 Cape Canaveral Air Force Station (CCAFS) launch pad, SpaceX’s first launch of the new year and decade hints at what is expected to follow over the course of 2020. In simple terms, the company’s ambitions have never been higher and anywhere from 36 to 38 orbital launches are scheduled between now and 2021 – some 65% of which will likely be internal Starlink missions.

If SpaceX manages to launch even half as many Starlink missions as it says it wants to this year, the company will be heading into 2021 with an operational internet satellite constellation nearly a thousand spacecraft strong – almost enough to ensure uninterrupted global coverage. Already, if SpaceX’s January 6th launch – known as Starlink V1 L2 (the second launch of v1.0 satellites) – goes as planned, the company will almost certainly become the owner of the world’s largest commercial satellite constellation less than eight months after it began launching its unique flat-packed spacecraft.

In a classic SpaceX move, the company’s Starlink satellite bus is a radical departure from all other commercial spacecraft, opting for a table-like rectangular shape that is extremely flat. While the rectangular shape – likely chosen for the extreme ease of manufacturing it should allow – significantly decreases packing efficiency, Starlink’s flat design and unique deployment mechanism means that SpaceX can fit an unprecedented 60 satellites (each weighing more than 250 kg or 550 lb) into a single lightly-modified Falcon 9 payload fairing.

Ultimately, SpaceX also design its Starlink satellites to be dramatically more robust than any comparable commercial spacecraft, meaning that they are meant to tolerate the violent acoustic launch environment without foam sound suppression panels that otherwise take up space inside Falcon 9’s fairing. Additionally, they are meant to survive the odd collision during their bizarre deployment, in which Falcon 9’s upper stage spins itself like a fan and releases the entire 60-satellite stack at once. Further, this means that Starlink satellites can be transported from their Washington state factory to Cape Canaveral, Florida far more easily and cheaply than almost any other spacecraft of a similar size and weight.

Falcon 9’s second fourth flight

It’s a mouthful, but SpaceX’s Starlink-2 mission will technically mark Falcon 9’s second fourth flight, meaning that it will be the second time a single Falcon 9 booster launches (and optimally lands) for the fourth time. Thrice-flown Falcon 9 booster B1049 has been assigned to support the launch.

The fourth completed Falcon 9 Block 5 booster, B1049 debuted on September 10th, 2018 on the Telstar 18V satellite launch, followed by a second flight (Iridium-8) in January 2019 and its third and most recent launch in May 2019. B1049’s most recent mission happened to be the very first dedicated Starlink launch, placing 60 Starlink v0.9 spacecraft in orbit in a sort of massive beta test of SpaceX’s cutting-edge satellite technology and design.

In support of Starlink V1 L1, the first launch of finalized Starlink v1.0 satellites, Falcon 9 booster B1048 became the first SpaceX rocket to successfully launch and land four times in November 2019, safely returning to shore aboard drone ship Of Course I Still Love You (OCISLY) a few days later. With (hopefully) two (and soon three) recovered boosters with four flights each under their belts, SpaceX will have a relative wealth of data it can then use to plot the way forward to fifth flights of boosters and beyond – halfway to the minimum Block 5 design goal of 10 launches apiece.

Tesla has improved Dashcam playback with an awesome new addition, as the company has launched a web-based version that is potentially easier to navigate and operate.

The tool is available at dashcam.tesla.com and will be enabled as your vehicle receives the 2026.20 Software Version. Clips that are captured by your Tesla will be available on the Online Dashcam Clip Viewer once the files on your car’s storage drive are encrypted.

Not a Tesla App first noticed the new feature, and states that once your Tesla updates to 2026.20, the car will automatically protect the clips with an encryption key that is uniquely tied to your owner account.

The web-based viewer should be easier to operate for most. All you will do is head over to dashcam.tesla.com and log in using your account credentials.

Ensure your vehicle is updated to 2026.20 in order for the web-based viewer tool to fetch your vehicle’s saved dashcam clips.

Currently, only a small percentage of owners are updated to this, so it may be a couple of weeks until a majority of owners in the fleet are able to access this feature.

Watching Dashcam clips on the Tesla smartphone app is quick and convenient, as they can also be easily downloaded and stored right on your smartphone.

However, the clips are sometimes tougher to navigate, and in order to get details like self-driving activation, speed, and turn signals, owners have to screen record the Tesla app and crop out the rest of the screen.

It could also be a massive storage saver as you’ll be able to download the Dashcam clips from the online viewer and save them to your laptop, desktop, a flash drive, or even an external hard drive. This will keep all your clips in one place.

Tesla Full Self-Driving attempts 150-mile stress test: the good and the bad

I recently took my Tesla Model Y running Full Self-Driving (Supervised) v14.3.3 over 150 miles on the Pennsylvania Turnpike in an effort to truly put the system under a stress test. There were a lot of good moments, and some bad, but overall, Full Self-Driving impressed me.

Last Thursday, I decided it was time to visit the Flight 93 National Memorial near Shanksville, PA. I go a few times a year, and it was a beautiful day. Others have taken some pretty lengthy drives using FSD, but I haven’t had the opportunity to really do something lengthy in quite a few months on an older version. I decided it was the perfect opportunity to try some things out.

I recorded the entire ride there on a GoPro, edited to highlight the crucial moments, and shared them on our social media accounts. If you want to watch them, I’ll share them throughout the piece, but I did not get to do a real breakdown of what I felt about its performance.

Overall Thoughts

I realize it is probably better to do a summation of its performance toward the end of the piece, but I feel like it is also reasonable to lead with this because I was overly impressed with how well it handled everything. The only moments where I felt a little bit of reason to touch the wheel, at least while traveling on the Turnpike and Rt. 30, were due to other drivers and their behaviors.

I have taken many drives to the Memorial over the past several years, and although it’s not incredibly long, it is a tiring drive. It’s about five hours both ways, close to 300 miles, and I think most of the exhaustion comes from the toll of sitting in the car and then visiting something that is pretty heavy to take in.

This was the first time I’ve ever taken the ride and not felt like I needed to avoid my vehicle after I got home. In the past, I could not even think about driving after I finally arrived at my house, but this was simply different.

It was nice to have something else take the drive for me, while I still had the freedom to take over if I chose to. It made the entire trip more enjoyable.

Full Self-Driving Recognizes Lane-Ending Arrows on Road

After traveling in the fast lane for a little while, FSD noticed the arrows on the road indicating the lane was coming to an end ahead. The car was also in the process of making a pass on a slower vehicle in the middle lane, but aborted this maneuver and backed off to get behind the vehicle.

I was really impressed by this because I thought that the car would absolutely try to make the pass, only to get in front of the other car, and then slow back down to 75 MPH:

Full Self-Driving Notices Veering Tractor Trailer, Adjusts Lane Positioning

My two rules of the road are never cruise in the fast lane and never drive next to a tractor-trailer. This clip is a perfect example as to why.

FSD v14.3.3 recognized this tractor-trailer attempting to change lanes while we were still next to it. The car shifted its lane positioning to the shoulder slightly to make room for the merging semi, executed the pass safely, and on we went.

I will admit this one made me a little nervous, but more so because of the 18-wheeler, and not because of the Tesla:

Full Self-Driving Follows the Rules of Tunnel Travel

Many people who are not familiar with Full Self-Driving and its capabilities are pretty limited in what they know about the really simple things it does well. Part of supervising FSD is being aware of things it might make mistakes with, and anticipating maneuvers it might want to make at the wrong time.

Entering the Blue Mountain Tunnel on the Turnpike, I was ready for FSD to attempt to get back into the right lane after making a pass on a tractor-trailer, but I was pleasantly surprised. Several signs outside the tunnel advise drivers to stay in the lane they’ve chosen while driving through the tunnel; this eliminates the possibility of an accident caused by lane changes, which would impede traffic on a crucial logistics route.

I was happy to see that Tesla Full Self-Driving v14.3.3 did not make this mistake:

Full Self-Driving Navigates Toll Plazas with Ease

I was interested to see how FSD would handle toll plazas, including the speed at which it would travel through them, and whether it would stop on the Turnpike at these booths, which have since been transitioned to a “Toll by Plate” system, which mails you a bill.

It was flawless:

Full Self-Driving Still Struggles with Parking from Time to Time

Since I took delivery in late August, I’ve never had a single instance of my Tesla struggling to park at a Supercharger. Other spots at the mall, market, or gym are another story.

This was the first time it did such a terrible job of backing into a spot. This required me to take over and manually park at another charger:

Full Self-Driving Gets Confused After Arriving at Its Destination

This was the first time I have ever experienced FSD getting confused and just circling the lot. The navigation continued to reroute to try to resolve the issue, but after four laps, I decided it was time to overtake the car’s controls and park manually:

This was a baffling behavior that I truly couldn’t explain. Other owners communicated that they have also experienced this issue.

Final Thoughts

I am so incredibly impressed by FSD that it has really made traveling stress-free. The two issues related to parking were not ideal, but to be fair, I usually take over when arriving at parking lots. However, this shortcoming is something Tesla has to make some serious progress with, because parking has truly stumped FSD at times.

Solving that will be a major breakthrough for autonomy, but Tesla has struggled with it for some time.

All in all, FSD v14.3.3 is unbelievably accurate and handles many of the more stressful maneuvers with ease, one of them being avoiding merging traffic on highways, which was shown above.

Some things that would be great to see improvements on are parking, Speed Profiles, which are relatively tough to adjust (I stayed in Standard for the duration of this drive), and, of course, navigation.

SpaceX’s amended S-1 is sparking a major Tesla merger conversation

A single line in SpaceX’s amended S-1 just sent Tesla stock down 5% in one day.

A single line buried in SpaceX’s amended S-1 filing is doing more to move Tesla’s stock price than anything Tesla itself has announced in months. The clause, disclosed as SpaceX prepares for what could be the largest IPO in Wall Street history, states that the company “may issue a significant amount of equity in connection with future transactions.” While this may be seen as boilerplate language in S-1 filings, the historical ties between SpaceX and Tesla, and with Elon Musk reportedly discussing a possible merger with close colleagues, investors are interpreting it as something closer to a signal.

The concern among institutional investors like Gary Black, managing director of The Future Fund, pointed directly to the amended filing on X, saying it “strongly suggests more SPCX equity will be issued,” which could potentially be used to acquire Tesla. He estimated such a deal could be 28% dilutive to Tesla shareholders since SpaceX would likely command a significantly higher valuation multiple. Black added that institutional investors he knows hate the idea of a combination because they prefer pure plays over conglomerates, which he said “nearly always gravitate to the lowest common multiple.”

The Tesla and SpaceX merger everyone is talking about is quietly building

The bull case runs the math differently. Tesla influencer and retail shareholder advocate AleXandra Merz pushed back on what she called a widespread misunderstanding of how merger-of-equals deals actually work. Rather than simply splitting the difference between two market caps, a merger exchange ratio is negotiated based on relative fair market values, meaning the lower valued company typically sees its stock reprice upward toward the deal value.

Under her model, SpaceX enters at a $2.5 trillion valuation and Tesla at $1.6 trillion, producing a combined entity worth $4.1 trillion split evenly between both shareholder groups. That implies Tesla’s side of the deal would be valued at $2.05 trillion, a gain of roughly $450 billion from its current market cap. She cited Dow-DuPont and CBS-Viacom as historical examples of how markets reprice both companies toward the announced exchange ratio after a deal is unveiled.


The SpaceX S-1 amendments also revealed just how much financial infrastructure already binds the two companies together. As Teslarati has reported, SpaceX purchased $697 million in Tesla Megapacks, $131 million in Cybertrucks, and the two companies have shared supply chain resources, and semiconductor fabrication plans since well before any merger conversation became public. A retail poll by Tesla influencer Sawyer Merritt is finding that 36% of respondents do not plan to buy SpaceX shares at IPO and 15.3% saying their decision depends on the valuation.


Whether the merger happens or not, the amended filing is seemingly moving markets and sharpened a debate that is no longer theoretical. SpaceX is weeks away from trading publicly, and Tesla shareholders are now watching every word of every filing for clues about what Musk plans to do next.
