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.

Just days after unveiling the Xiaomi YU7, a vehicle that is considered as the Model Y’s strongest competitor yet, Xiaomi CEO Lei Jun gave a nod of respect to Tesla and its Full Self-Driving (FSD) program. 

In a post on Weibo, Lei Jun highlighted the remarkable nature of Tesla’s first autonomous delivery. He also acknowledged that Xiaomi still has much to learn in the electric vehicle industry.

Xiaomi CEO’s Nod of Respect

Lei Jun’s comments about Tesla’s FSD delivery were shared as a response to Tesla VP Grace Tao’s post about the recent feat. The Tesla VP shared several key aspects of the delivery, from the fact that there was no driver in the Model Y to the vehicle reaching over 70 mph as it drove to its owner. 

“For the first time in history, the vehicle was delivered to the owner by itself. There was no driver or remote control throughout the journey, and the maximum speed reached 115 kilometers per hour, and it arrived safely at the customer’s door. This is a brand new Model Y. Tesla always surpasses imagination with disruptive innovation. A new era, exciting!” Tao wrote in her post.

In his response, the Xiaomi CEO acknowledged Tesla’s incredible feat. “Tesla is indeed amazing, leading the industry trends in many areas, especially FSD. We still have to continue learning!” he wrote.

Xiaomi’s Recent Tesla Competitor

The Xiaomi CEO’s comments show that Tesla’s projects and leadership garner a lot of respect in the global electric vehicle sector. While Tesla and Elon Musk tend to be media punching bags in the United States and Europe, the company and its CEO seem to be taken very seriously in China. This was despite China being the world’s most competitive electric vehicle market.

Xiaomi itself has become one of Tesla’s strongest rivals in China, with its first car, the SU7, bringing the fight to the Tesla Model 3. Its most recent vehicle, the YU7, could very well be the Model Y’s most legitimate rival yet, as it is more affordable, bigger, and more feature-laden than Tesla’s best-selling crossover. The YU7 has garnered quite a lot of attention, with Xiaomi receiving 200,000 firm orders for the vehicle within the first three minutes of its launch.

Tesla silences FSD critics by posting full video of Model Y delivering itself to customer

When Elon Musk posted that the first Tesla had delivered itself to its owner, critics were quick to question his statement.

It is no secret that Tesla still has ardent critics today, many of whom remain convinced that the company and its leadership are lying about Full Self-Driving (FSD) and its capabilities. It was then no surprise that when Elon Musk announced that the first Tesla had successfully delivered itself to its owner, critics were quick to question the CEO’s statement.

Videos of the all-electric crossover’s solo drive to its owner soon silenced Tesla critics and their claims.

Tesla Posts FSD Video Proof—Twice

While Musk’s post on X about a Tesla delivering itself to a consumer was a notable update, his claims were not accompanied by any video. This was taken by some Tesla critics as a hint that the CEO’s claims were false, and that the feat probably did not happen. Musk, for his part, noted that Tesla would soon be posting a video of the self-driving car’s drive to its owner.

The electric vehicle community did not have to wait very long. Tesla later posted a video of its first autonomous vehicle delivery ever on X, much to the shock of social media users. As could be seen in the video, a Tesla Model Y was able to travel about 30 minutes on its own, from the end of Giga Texas’ production line to the home of its owner, several miles away. Tesla even posted the vehicle’s full 30-minute drive on its official X account later on. 

Critics Are Still Skeptical, But It’s Cope at this Point

Of course, Tesla skeptics remained unconvinced that the feat was legitimate, with some pointing out that the Model Y customer seems to have had an X account for years but never posted, at least until his car was delivered. Others also claimed that the whole setup seemed suspicious since the Model Y looked like it had manufacturer plates as it navigated Austin’s streets.

These concerns, however, do not seem like very strong arguments, especially at this point. Based on the evidence, it seems like Tesla really has figured out autonomous driving, and its cars are now able to operate safely on real-world roads on their own. Many have also become silent in their criticisms of Tesla’s FSD feat, especially after the company posted the full video of the Model Y’s autonomous drive. Overall, Tesla critics may remain doubtful about the company and Musk’s claims, but these concerns seem to have become forced at best.

Ford CEO favors Waymo’s LiDAR approach over Tesla’s vision-only self-driving

Farley stated that Waymo’s LiDAR-based approach made “more sense.”

Ford CEO Jim Farley shared some skepticism about Tesla’s camera-only approach to self-driving during a recent appearance at the Aspen Ideas Festival. When asked to compare Waymo and Tesla’s autonomous driving systems, Farley stated that Waymo’s LiDAR-based approach made “more sense,” citing safety, consumer trust, and the limitations of camera-based models.

Waymo’s LiDAR vs. Tesla’s Vision-Only Approach

Farley was speaking with author Walter Isaacson when he made his comments about Tesla and Waymo’s self-driving systems. As they were conversing about autonomous cars, Isaacson asked Farley which approach to self-driving he preferred.

“To us, Waymo,” Farley said, though he also stated that both Tesla and Waymo have “ made a lot of of progress” on self-driving, as noted in a Fortune report. He also confirmed that he has had conversations about the matter with Tesla CEO Elon Musk. Despite this, he said that Ford still considers LiDAR as a pivotal part of autonomous driving. 

“When you have a brand like Ford, when there’s a new technology, you have to be really careful. We really believe that LiDAR is mission critical… Where the camera will be completely blinded, the LiDAR system will see exactly what’s in front of you,” the Ford CEO stated. 

Tesla and Ford’s self-driving plans

Tesla recently launched a limited Robotaxi service in Austin, which uses autonomous cars with safety monitors in the front passenger seat. While controversial, Musk has maintained that Tesla’s vision-only approach will ultimately prove safer and more cost-effective in the long term. Tesla seems to be making headway towards this goal, with Musk stating recently that the first Model Y has been delivered autonomously to a customer in Austin.

Ford, for his part, is not pursuing its own fully autonomous, urban-driving system anymore. Instead, the company is focusing on “high-speed, eyes-off” experiences like BlueCruise. Ford does plan to partner with a company that has achieved true autonomous driving in the future, as soon as the technology is available.
