Boeing Starliner joins SpaceX’s Crew Dragon at the International Space Station

Published

on

Boeing’s Starliner crew capsule has successfully rendezvoused, approached, and docked with the International Space Station for the first time, marking major several major milestones for NASA and its second Commercial Crew partner.

Starliner’s second orbital flight test (OFT-2) began as expected with a near-flawless May 19th launch on a United Launch Alliance (ULA) Atlas V rocket. As thousands of employees and stakeholders held their collective breath, the uncrewed prototype safely detached from Atlas V’s Centaur upper stage and propelled itself the rest of the to a stable parking orbit. Two and a half years after their first attempt, Boeing and NASA were then finally able to send Starliner on its way to the International Space Station (ISS) and prepare for proximity operations.

As previously discussed on Teslarati, Starliner making it through the first hour or so of flight without running into a catastrophic problem was already a huge milestone for Boeing and a massive improvement over the company’s last two orbital flight test attempts.

“The story of Starliner’s tortured orbital flight test (OFT) campaign began in earnest on December 20th, 2019, when an uncrewed prototype first attempted to launch to the International Space Station (ISS) atop a United Launch Alliance (ULA) Atlas V rocket. A major software bug that could have been easily detected with even the most basic integrated hardware-in-the-loop prelaunch testing caused Starliner to lose control the moment it separated from Atlas V. After hundreds of seconds of unplanned burns of its many attitude control thrusters, Boeing finally regained control but Starliner no longer had enough propellant to safely reach the ISS.

Boeing would later catch and correct another unrelated software bug mere hours before Starliner’s planned reentry and recovery that, if undetected, could have caused the spacecraft’s capsule and service sections to crash into each other shortly after separation.

On July 30th, 2021, shortly before a different uncrewed Starliner was scheduled to reattempt the first Orbital Flight Test, the launch was aborted. Boeing and NASA later reported that 13 of Starliner’s 24 main oxidizer valves failed to open during a prelaunch test just a few hours before liftoff. It was eventually concluded that faulty Aerojet Rocketdyne-supplied valves and poor Boeing integration enabled water intrusion and extensive corrosion. The next OFT-2 launch attempt was delayed by almost ten months, as a result.”

Instead of calamity, Starliner’s second OFT and third OFT attempt was mainly greeted with success. After reaching orbit, the spacecraft began raising and ‘phasing’ its orbit to rendezvous with the ISS and completed all the burns and navigation required without major issues. Finally, after several intentional test maneuvers and about an hour of unplanned troubleshooting, Starliner began its final approach and successfully docked with the ISS – joining a SpaceX Crew Dragon – at 8:28 pm EDT on May 20th (00:28 UTC 21 May).

Starliner’s successful docking made it the fourth, fifth, or sixth US spacecraft to reach the ISS, joining the Space Shuttle, three main variants of SpaceX’s Dragon, and Orbital ATK’s (now Northrop Grumman) Cygnus cargo vehicle. It also marked the first time that both NASA Commercial Crew Program vehicles have been simultaneously docked at the space station – a reassuring sign of a future with redundant access after years of Boeing delays forced SpaceX to temporarily become NASA’s sole source of astronaut transportation. While odds are good that SpaceX will ultimately be required to singlehandedly maintain NASA access to the ISS for seven six-month ‘expeditions’ (>3 years), Starliner’s thus-far-successful OFT2 mission significantly improves the odds that the Boeing spacecraft will be fully ready within a year or two.

Nonetheless, Starliner must still safely depart the ISS, lower its orbit, reenter Earth’s atmosphere, and safely touch down for recovery and reuse. Starliner has already accomplished all of those tasks during OFT1, but tensions will still be high. Additionally, Starliner’s performance during OFT2 has been far from perfect. Aside from a few minor issues with coolers and radiators, Boeing and NASA revealed that four of the spacecraft’s several dozen thrusters (two larger maneuvering/control thrusters and two smaller attitude control thrusters) – had failed by the time it was docked. During OFT1, as many as 13 thrusters failed as a result of minutes of unplanned burns, but Boeing was able to recover all but one before reentry.

Technically, that means that both missions have demonstrated the solid redundancy of Starliner’s propulsion systems, but NASA will undoubtedly demand that Boeing determine probable root causes and qualify fixes before greenlighting Starliner’s first Crewed Flight Test (CFT). For SpaceX, it took 14 months after Crew Dragon’s first near-flawless uncrewed debut for NASA to agree to proceed with a crewed flight test. However, during post-flight testing, the capsule that support Demo-1 catastrophically exploded, triggering a several-month investigation. The effect of a few failed thrusters is decidedly less severe, so Starliner might not have to wait as long for CFT. With any luck, that means that NASA will have two fully-redundant astronaut transport spacecraft available and operational by the end of 2023, if not earlier.

Tesla confirms Robotaxi is heading to five new cities in the U.S.

After launching in Austin, Texas, in late June and the Bay Area of California just a few weeks later, Tesla has been attempting to expand its Robotaxi suite to new states and cities in the U.S., and even outside of the country.

Tesla Robotaxi will hit five new cities in the United States in the coming months, the company confirmed.

After launching in Austin, Texas, in late June and the Bay Area of California just a few weeks later, Tesla has been attempting to expand its Robotaxi suite to new states and cities in the U.S., and even outside of the country.

The Robotaxi suite is a ride-hailing service Tesla offers, but the details of it change with each jurisdiction, as regulations vary. For example, in Austin, Tesla can operate the Robotaxi suite without anyone in the driver’s seat, as long as the vehicle does not enter a freeway.

In the Bay Area, a Safety Monitor rides in the driver’s seat, essentially acting as the vehicle operator with Full Self-Driving controlling the car.

The local regulations and how Tesla handles them will continue to be a relevant part of the discussion, especially as the company aims to expand the Robotaxi program to different areas. This has been a primary focus of the company for several months, especially within the United States.

CEO Elon Musk said that Tesla was aiming to launch Robotaxi in Nevada, Arizona, and Florida. However, the company detailed five specific cities where it will launch Robotaxi next during the Annual Shareholder Meeting on Thursday.

Tesla will launch Robotaxi in Las Vegas, Phoenix, Dallas, Houston, and Miami next, broadening its Service Area for the suite to more major cities across the U.S.

It has said it plans to offer the service to half of the U.S. population by the end of the year, but it does not seem as if it will expand to more than a handful of cities this year, which is still tremendous progress, all things considered.

As far as autonomy is concerned, Tesla has always had lofty expectations and has made some even loftier statements.

At the Shareholder Meeting, Musk said that the company would likely be able to enable vehicle owners to text while the vehicle drives, alleviating them from potentially having some of the responsibility they have behind the wheel.

It is not confirmed that Tesla will roll this out in the next few months, but Musk said there is a possibility.

Tesla launches another new Model Y trim at a bargain price with massive range

It is the second most-affordable Model Y trim level in China, trailing the base Rear-Wheel-Drive and coming in under the All-Wheel-Drive.

Tesla has launched yet another new Model Y trim level, but this time it is in China, and it is at a bargain price.

It also has an insane range rating.

On Friday, Tesla launched the new Model Y Long Range Rear-Wheel-Drive in China, priced at 288,500 yuan ($40,500), an incredible deal considering it is not a stripped-down version of the vehicle like the Model Y Standard.

It is the second most-affordable Model Y trim level in China, trailing the base Rear-Wheel-Drive and coming in under the All-Wheel-Drive.

The big appeal with this new Model Y trim is obviously its price, but its range rating is also one of the best we’ve seen. Rated at 821 kilometers on the CLTC scale, it converts to 510 miles. It uses a 78.4 kWh CATL battery.

Converted to real-world range, however, that 821-kilometer range rated by the CLTC actually is equivalent to about 357 miles on the EPA scale, which is still a very respectable number and comes in at a higher range than the Long Range All-Wheel-Drive configuration that is available in the U.S.

Tesla has truly brought a wide variety of Model Y trims to the Chinese market, including a new Model Y L configuration that features a slightly longer wheelbase, as well as additional interior features like extended thigh legrests and captain’s chairs with armrests.

It is unclear whether Tesla will bring a Premium Rear-Wheel-Drive option of the Model Y to the U.S., especially as it has already rolled out four configurations of the all-electric crossover in the market. With the new Standard offerings, Tesla will likely keep its lineup as simple as possible.

However, the company has hinted that there is a slim possibility the Model Y L could come to the U.S. sometime late next year, but CEO Elon Musk said that it is not a guarantee.

Tesla is more concerned with self-driving efforts in the U.S., and despite calls from customers for larger vehicles, it does not seem concerned with making them available, at least not for now.

Tesla’s new Model Y Performance is set to arrive in a new market in Q1 2026, a company executive confirmed on Friday.

The lightning-fast trim level of the all-electric crossover packs a variety of new improvements, including more range and better acceleration, thanks to aerodynamic improvements and other performance-based changes.

It was initially launched in Europe, and then it made its way to the United States. However, it will soon be available in a new market: Canada.

Raj Jegannathan, a Tesla executive, confirmed on Friday that the company would be bringing its Performance trim of the Model Y to the Canadian market early next year:

Interestingly, the Model Y Performances that enter the Canadian market will likely come from Gigafactory Berlin and not Gigafactory Texas, even though it is logistically more advantageous.

There is a 25 percent tariff on U.S.-built vehicles currently, and Tesla has been sending Germany-built Model Y vehicles to Canada to avoid this and keep prices reasonable for customers.

Some Model Y owners in Canada have already confirmed that their units came from the German production facility, not the United States.

Model Y Performance deliveries have not yet started in the United States, but are slated for late November or early December.

Tesla refined the Model Y Performance’s exterior design with new front and rear fascia designs, a new performance carbon spoiler, 21″ Arachnid wheels and tires, and adaptive damping to help with better handling.

There are also new Drive Modes for better control during high-speed driving.

It also packs the same improvements as the new Model Y features over its predecessors, including acoustic glass and premium sound-damping materials for a quieter cabin, and heated and ventilated front sport seats.

In the United States, it is priced at $57,490. It will very likely be higher in Canada due to logistics costs and other factors.
