SpaceX Falcon 9 ends year as the most-launched rocket of 2020

Published

With just a few global launches left before 2021 and SpaceX’s last December launch behind it, it’s now safe to say that Falcon 9 has officially ended the year as the world’s most-launched rocket of 2020.

On December 19th, Falcon 9 booster B1059 lifted off for the fourth time, carrying a secretive US spy satellite to Low Earth Orbit (LEO) and marking SpaceX’s 26th successful launch and 23rd landing of 2020 – an exactly biweekly annual launch cadence. Barring several surprise launches, Falcon 9 will end the year as the world’s most-launched rocket and – by best measures – the world’s most reliable rocket, setting SpaceX up for a potentially unprecedented 2021.

After NROL-108, SpaceX’s Falcon 9 will almost certainly be the most-launched rocket of 2020.

Perhaps thanks to Starlink and any number of unknown hardware, software, and operational refinements, SpaceX has crushed its previous annual launch record – 21 flights, set in 2018 – by almost 25%. In 2020, Starlink missions represented more than half of Falcon 9’s 26 launches, placing almost 840 operational satellites in orbit over the course of 14 flights.

Thanks to Falcon 9’s record-breaking performance, in a single year, Starlink has become world’s largest satellite constellation by at least a factor of three to four, if not five or more.

Following SpaceX’s NROL-108 mission, perhaps two or three more international launches are planned between now and 2021. Altogether, the world’s launch providers are on track to successfully complete around 103 launches, almost a quarter of which can be credited to Falcon 9 alone. No other single rocket came close: Russia’s R-7 (Soyuz 2.1) family managed 14 successful flights, while five fairly distinct variants of China’s Long March 2, 3, and 4 rockets completed 24 launches in 2020.

In general, China is on track to complete 38 orbital launch attempts (33-34 of which were successful) in 2020, either narrowly edging out or tying the US (37 attempts; 34 successes).*

Perhaps most importantly, in large part thanks to a continuous stream of Falcon 9 reusability firsts, SpaceX appears to be on track to crush its impressive 2020 launch record in 2021. Checking off the first fourth, fifth, and sixth reuses of Falcon 9 boosters, as well as the first flight of a payload fairing for the third time, very little doubt remains that SpaceX will be able to achieve (and likely surpass) a 10-flight goal set for each Falcon booster back in 2018.

In the final three months of 2020, SpaceX managed an impressive 10 orbital launches, including milestone missions like Crew Dragon’s operational astronaut launch debut, the first flight of an upgraded Cargo Dragon spacecraft, and Falcon 9’s first West Coast launch in ~18 months.

Ultimately, by completing almost 40% of its annual launches in a single quarter, SpaceX has proven that an annual cadence of 40+ launches – and CEO Elon Musk’s stated goal of 48 flights – is well within reach next year.

Tesla seems to have fixed one of Full Self-Driving’s most annoying features

Tesla seems to have resolved an issue that many users of the Full Self-Driving suite complained about recently.

Tesla seems to have listened to drivers and owners who complained about a very annoying feature that monitors the eyes of the vehicle operator while using the Full Self-Driving suite.

Earlier this month, owners complained that versions of Full Self-Driving Supervised were too quick to alert drivers of their eyes going off the road, which is required for operation.

Tesla to fix an FSD driver monitoring annoyance, Elon Musk hints

If you’re doing something as simple as adjusting HVAC settings or changing Autopilot speed offset, the cabin-facing camera would alert the driver that their eyes need to be on the road.

It was incredibly quick to warn you, and many argued that changing these features while the vehicle is using FSD is safer than doing it while operating the car manually.

After several complaints, Tesla CEO Elon Musk said he agreed with the fact that FSD would warn drivers so quickly. When a user on X noted that “I can’t even glance at the display to add a nav stop without getting yelled at” and stated it was what they hated most about FSD, Musk replied, “You’re right.”

Tesla is now rolling out a new update of the FSD suite with v13.2.9, which includes various improvements. One of which appears to be a less dramatic driver monitoring system, which includes perhaps a slightly longer grace period before it will alert you to look at the road.

Several owners are reporting they’ve noticed a change, with it being less restrictive than previously:

Driver monitoring is very important, considering people do abuse FSD and its capabilities. It is important to pay attention, even if you are overwhelmingly confident in the abilities of FSD, because, in the event of an accident, Tesla will be the one to take the bad publicity for it.

This is even if the driver is found liable for the accident.

However, from personal experience, the alerts it gave were slightly dramatic, and I felt that they were over the top. I was admonished by the driver monitoring system for simply adjusting the Autopilot speed offset.

Many owners welcome this change. FSD is being refined with every update, becoming more robust, accurate, and less naggy with its requests.

Tesla details latest safety addition with new Model Y

Tesla’s newest safety feature isn’t even visible to the human eye when you get in the new Model Y

Published

on

Tesla has detailed the addition of its latest safety feature that comes standard with the new Model Y. It is a feature that has been in development for several years and aims to assist in saving lives while also enabling other safety features.

Within the past few years, Tesla has been developing an in-cabin radar that was aimed at detecting humans left in the vehicle that typical cameras would not detect. It was a feature that was initially developed to save the lives of children, who die a handful of times each year from being left in cabins without air conditioning.

Teslarati first reported on the development of an in-cabin radar system several years ago through Federal Communications Commission (FCC) documents, which showed Tesla was hoping to gain approval for a wave sensor that would detect heartbeats instead of relying on cameras.

The company has started using the in-cabin radar system with the new Model Y, which has been available in the U.S. for several months. Tesla has released the new Model Y Owner’s Manual online, which gives us a first-hand look at the details it released on the various advancements it has made with the newest version of the best-selling vehicle in the world.

As shown above, the Model Y’s new cabin radar is located above the rearview mirror and behind the ceiling gear shifter buttons.

Tesla describes its duties:

“Cabin radar can detect the presence of people inside the vehicle and use the measurements to determine occupancy. Cabin radar supports certain vehicle and safety features, including driver detection, seat occupancy, Occupant Classification System (OCS), and auto parking brake engagement.”

Interestingly, Tesla has added that it will be able to enable auto parking brake engagement, a great feature for when someone exits the vehicle. In the past, we knew it would handle driver and occupant protection, but we did not recognize its value as a way to enable a parking brake.

Tesla’s Elon Musk clarifies shocking Optimus fact

Musk clarified that while Optimus is already impressive today, it is still very far from its planned final form.

This week has been a tour de force of Tesla Optimus demonstrations. But even with the humanoid robot’s already impressive capabilities, CEO Elon Musk dropped a comment that truly made Optimus even more exciting. 

Inasmuch as Optimus today is likely one of the most advanced humanoid robots in the industry, it is still nothing close to what Tesla really wants to create.

Optimus Demonstrations

Optimus’ demonstrations this week caught headlines because they showed the humanoid robot performing impressive dance moves. Initially, a video posted by Elon Musk on social media platform X showed Optimus dancing while being tethered to a cable. A follow up video upped the ante, with Optimus performing actual ballet moves without any support.

Comments from Tesla Vice President of Optimus (Tesla Bot) Milan Kovac revealed that the humanoid robot’s movements were fully learned in simulation and zero-shot transferred to real without extra training. Elon Musk later joked that he would be accompanied by a troupe of dancing Optimus robots at the 2024 Tesla Annual Shareholder Meeting.

Not Even Close

But in another follow-up comment on X, Musk clarified that while Optimus is already impressive today, it is still very far from its planned final form. This was quite surprising as the humanoid robot is already in initial production at the Fremont Factory. Even in its current state, Optimus also looks production-ready. Elon Musk even noted that Optimus robots are just walking around Tesla’s factories today around the clock, charging themselves as needed.

With this in mind, one could wonder what Optimus’ final form could really be like. While the humanoid robot’s current iteration is already pretty sleek, perhaps Tesla is still developing Optimus until its appearance could mirror the robot’s static display model that the company showed off back in 2021. That Optimus model featured very human proportions and joints, making it look more like an android from a sci-fi flick than a humanoid robot with obvious mechanical parts.
