SpaceX Dragon spacecraft caught by robotic space station arm for the last time

On March 9th, SpaceX’s CRS-20 Cargo Dragon completed an uneventful journey to the International Space Station (ISS), where the spacecraft was successfully captured giant robotic arm for the last time.

Barring several major surprises, Dragon’s March 9th capture was the last time a SpaceX spacecraft berthed with a space station for the foreseeable future – possibly forever. Referring to the process of astronauts manually catching visiting vehicles and installing them on an airlock with a giant, robotic arm, berthing is a much younger technology than docking and was developed as an alternative for a few particular reasons. Perhaps most importantly, the Common Berthing Mechanism (CBM) ports used by Cargo Dragon, Cygnus, and HTV spacecraft are more than 60% wider than standard docking ports. In other words, spacecraft that berth can transport substantially larger pieces of cargo to and from the space station.

More significantly, however, the CBM standard came about in large part due to the decision to assemble the ISS out of 16 pressurized segments, each separately launched into orbit. Measuring about 1.25m (4.2 ft) wide, the CBM ports that connect most of the space station’s 16 livable segments make the ISS far more practical for the astronauts that crew it, while also allowing for larger hardware to be moved between each module. With Crew Dragon, design requirements meant that SpaceX had to move from berthing to docking, a trait SpaceX thus carried over when it chose to base its Cargo Dragon replacement on a lightly-modified Crew Dragon design.

Now verging on routine, Cargo Dragon capsule C112 began its final approach to the International Space Station on March 9th, pausing at set keep-out zones while SpaceX operators waited for NASA and ISS approval to continue. After several stops, Dragon arrived at the last hold point – some 10m (33 ft) away from the station – and NASA astronaut Jessica Meir manually steered Canadarm2 to a successful capture, quite literally grabbing Dragon with a sort of mechanical hand.

At that point, Dragon – like a large ship arriving in port with the help of tugboats – is in the hands of external operators. At the ISS, Canadarm2 essentially flips itself around with Dragon still attached, carefully and slowly mating the spacecraft with one of the station’s free berthing ports. Unlike docking ports, the active part of a berthing port is located on the station’s receiving end, where electromechanical latches and bolts permanently secure the spacecraft to the station and ensure a vacuum seal.

Finally, once berthing is fully complete, ISS astronauts can manually open Dragon’s hatch, giving them access to the two or so metric tons (~4000 lb) of cargo typically contained within. All told, the process of berthing is relatively intensive and expensive in terms of the amount of time station astronauts and NASA ground control must spend to complete a single resupply mission. From start to finish, excluding training, berthing takes a crew of two station astronauts some 9-12 hours of near-continuous work from spacecraft approach to hatch open.

One definite benefit of the docking approach Crew Dragon and Cargo Dragon 2 will use is just how fast it is compared to berthing. Because docking is fundamentally autonomous and controlled by the spacecraft instead of the station, it significantly reduces the workload placed on ISS astronauts. Crew members must, of course, remain vigilant and pay close attention during the critical approach period, particularly with uncrewed Cargo Dragon 2 spacecraft. However, the assumption is always that the spacecraft will independently perform almost all tasks related to docking, short of actually offloading cargo and crew.

For now, CRS-20 will likely be SpaceX’s last uncrewed NASA cargo mission for at six months. CRS-21 – Cargo Dragon 2’s launch debut – is currently scheduled no earlier than (NET) Q4 2020. Nevertheless, Crew Dragon’s next launch – also its astronaut launch debut – could lift off as early as May 2020, just two months from now. With both SpaceX’s crew and cargo missions soon to consolidate around a single spacecraft, the odds are good that Dragon 2 will wind up flying far more than Dragon 1, and the start of its increasingly common launches is just around the corner.

Tesla expands Robotaxi app access once again, this time on a global scale

Tesla said recently it plans to launch Robotaxi in Miami, Houston, Las Vegas, Phoenix, and Dallas.

Tesla has expanded Robotaxi app access once again, but this time, it’s on a much broader scale as the company is offering the opportunity for those outside of North America to download the app.

Tesla Robotaxi is the company’s early-stage ride-hailing platform that is active in Texas, California, and Arizona, with more expansion within the United States planned for the near future.

Tesla said recently it plans to launch Robotaxi in Miami, Houston, Las Vegas, Phoenix, and Dallas.

The platform has massive potential, and Tesla is leaning on it to be a major contributor to even more disruption in the passenger transportation industry. So far, it has driven over 550,000 miles in total, with the vast majority of this coming from the Bay Area and Austin.

First Look at Tesla’s Robotaxi App: features, design, and more

However, Tesla is focusing primarily on rapid expansion, but most of this is reliant on the company’s ability to gain regulatory permission to operate the platform in various regions. The expansion plans go well outside of the U.S., as the company expanded the ability to download the app to more regions this past weekend.

So far, these are the areas it is available to download in:

  • Japan
  • Thailand
  • Hong Kong
  • South Korea
  • Australia
  • Taiwan
  • Macau
  • New Zealand
  • Mexico
  • U.S.
  • Canada

Right now, while Tesla is focusing primarily on expansion, it is also working on other goals that have to do with making it more widely available to customers who want to grab a ride from a driverless vehicle.

One of the biggest goals it has is to eliminate safety monitors from its vehicles, which it currently utilizes in Austin in the passenger’s seat and in the driver’s seat in the Bay Area.

A few weeks ago, Tesla started implementing a new in-cabin data-sharing system, which will help support teams assist riders without anyone in the front of the car.

Tesla takes a step towards removal of Robotaxi service’s safety drivers

As Robotaxi expands into more regions, Tesla stands to gain tremendously through the deployment of the Full Self-Driving suite for personal cars, as well as driverless Robotaxis for those who are just hailing rides.

Things have gone well for Tesla in the early stages of the Robotaxi program, but expansion will truly be the test of how things operate going forward. Navigating local traffic laws and gaining approval from a regulatory standpoint will be the biggest hurdle to jump.

Tesla gets price target boost, but it’s not all sunshine and rainbows

Tesla received a price target boost from Morgan Stanley, according to a new note on Monday morning, but there is some considerable caution also being communicated over the next year or so.

Morgan Stanley analyst Andrew Percoco took over Tesla coverage for the firm from longtime bull Adam Jonas, who appears to be focusing on embodied AI stocks and no longer automotive.

Percoco took over and immediately adjusted the price target for Tesla from $410 to $425, and changed its rating on shares from ‘Overweight’ to ‘Equal Weight.’

Percoco said he believes Tesla is the leading company in terms of electric vehicles, manufacturing, renewable energy, and real-world AI, so it deserves a premium valuation. However, he admits the high expectations for the company could provide for a “choppy trading environment” for the next year.

He wrote:

“However, high expectations on the latter have brought the stock closer to fair valuation. While it is well understood that Tesla is more than an auto manufacturer, we expect a choppy trading environment for the TSLA shares over the next 12 months, as we see downside to estimates, while the catalysts for its non-auto businesses appear priced at current levels.”

Percoco also added that if market cap hurdles are achieved, Morgan Stanley would reduce its price target by 7 percent.

Perhaps the biggest change with Percoco taking over the analysis for Jonas is how he will determine the value of each individual project. For example, he believes Optimus is worth about $60 per share of equity value.

He went on to describe the potential value of Full Self-Driving, highlighting its importance to the Tesla valuation:

“Full Self Driving (FSD) is the crown jewel of Tesla’s auto business; we believe that its leading-edge personal autonomous driving offering is a real game changer, and will remain a significant competitive advantage over its EV and non-EV peers. As Tesla continues to improve its platform with increased levels of autonomy (i.e., hands-off, eyes-off), it will revolutionize the personal driving experience. It remains to be seen if others will be able to keep pace.”

Additionally, Percoco outlined both bear and bull cases for the stock. He believes $860 per share, “which could be in play in the next 12 months if Tesla manages through the EV-downturn,” while also scaling Robotaxi, executing on unsupervised FSD, and scaling Optimus, is in play for the bull case.

Will Tesla thrive without the EV tax credit? Five reasons why they might

Meanwhile, the bear case is placed at $145 per share, and “assumes greater competition and margin pressure across all business lines, embedding zero value for humanoids, slowing the growth curve for Tesla’s robotaxi fleet to reflect regulatory challenges in scaling a vision-only perception stack, and lowering market share and margin profile for the autos and energy businesses.”

Currently, Tesla shares are trading at around $441.

Tesla Optimus dramatically collapses after teleoperator mishap

It seemed blatantly obvious that whoever was controlling the Optimus robot from behind the scenes did not disconnect their ability to manipulate its movements

Tesla Optimus dramatically collapsed after a teleoperator mishap at the company’s “Future of Autonomy Visualized” event in Miami this past weekend.

It seemed blatantly obvious that whoever was controlling the Optimus robot from behind the scenes did not disconnect their ability to manipulate its movements, then left the controls, causing Optimus to collapse.

A video captured at the event shows Optimus doing a movement similar to taking a headset off, likely what the teleoperator uses to hear guest requests and communicate with other staff:

After the headset removal motion was completed, Optimus simply collapsed backward, making for an interesting bit of conversation. While it was a mishap, it was actually pretty funny to watch because of the drama displayed by the robot in the situation.

This was obviously a mistake made by the teleoperator, and does not appear to be a spot where we can put any sort of blame on Optimus. It would have likely just stood there and waited for controls to resume if the teleoperator had disconnected from the robot correctly.

However, details are pretty slim, and Tesla has not announced anything explaining the situation, likely because it seems to be a pretty face-value event.

Tesla Optimus shows off its newest capability as progress accelerates

The Tesla Optimus program has been among the most hyped projects that the company has been working on, as CEO Elon Musk has extremely high hopes for what it could do for people on Earth. He has said on several occasions that Optimus should be the most popular product of all time, considering its capabilities.

Obviously, the project is still a work in progress, and growing pains are going to be part of the development of Optimus.

In its development of Optimus Gen 3, Tesla has been working on refining the forearm, hand, and fingers of Optimus, something that Musk said is extremely difficult. However, it’s a necessary step, especially if its capabilities will not be limited by hardware.

All in all, Optimus has still been a very successful project for Tesla, especially in the early stages. The company has done an excellent job of keeping Optimus busy, as it helps with serving customers at events and the Tesla Diner, and is also performing tasks across the company’s manufacturing plants.
