SpaceX aims for a burst of December launches despite recent delays

Published

on

Originally scheduled to launch on December 4, SpaceX’s thirteenth resupply mission to the International Space Station (ISS) has been pushed back to no earlier than Friday, December 15 after routine preflight checks identified potential contaminants in the Falcon 9 launch vehicle’s upper stage fuel lines.

The past six weeks have been something of an outlier in an otherwise relentless series of 2017 launches for SpaceX. In early November, defects in payload fairings were discovered at the company’s Hawthorne, CA factory and quickly traced to the Zuma mission’s fairing, at that point already vertical and prepared to launch from Kennedy Space Center. SpaceX chose to pause its launch indefinitely as it investigated the fairings already delivered to its several launch pads and began the process of either repairing or replacing those impacted. The CRS-13 Cargo Dragon mission soon took precedent as Zuma remained on hold.

Although CRS-13 does not require a payload fairing and was thus unaffected by SpaceX’s ongoing investigation, the mission was scheduled to be launched from Launch Complex-40, essentially a new pad after ten months of extensive repairs and upgrades. This translated into a few days of additional delays as the SpaceX launch crew thoroughly tested the pad’s new systems and pushed towards static fire of the flight proven Falcon 9 booster, successfully completed on December 6 after an additional handful of days of pad-related delays. This pushed the launch date from the 4th to the 8th, then the 12th and the 13th to accommodate further limited testing in order to ensure pad readiness. However, routine tests revealed a possible fuel line contamination in Falcon 9’s second stage, and SpaceX delayed the mission an additional 48 hours to resolve the problem. CRS-13 is now aiming for launch no earlier than 7:35am/10:35am PST/EST on December 15, but the window is instantaneous and any additional delays would push the launch into late December, at which point Cape Canaveral Air Force Station returns to operational status with the conclusion of winter holidays.

Although LC-40 suffered through its own teething period of bugs and testing while returning to life, there is a certain irony in the fact that a bug in the only wholly new component of CRS-13’s Falcon 9 rocket has been the most recent cause of delay; both the Falcon 9 booster and Cargo Dragon capsule are refurbished, flight-proven hardware, although both the trunk and heat shield of the Dragon were likely replaced with new components. There is something to be said about the logical nature of truly “flight-proven” hardware being more trustworthy than completely new alternatives, but it is far more likely that the upper stage contamination can be largely traced back to the new pad hardware.

Although Teslarati’s launch photographer Tom Cross has been battered about by Zuma and CRS-13 delays, SpaceX has demonstrated an admirable level of patience and caution, risking significant delays to their launch manifest in order to best ensure the safety and reliability of their launch services. While delays are painful in the spaceflight fan business, they are impermanent and secondary to safety and success. SpaceX will undoubtedly return to their regular programming in no time at all, with the West-coast launch of Iridium-4 and first pad rollout of Falcon Heavy up next on the docket. Stay tuned!

Elon Musk says Tesla will take Safety Drivers out of Robotaxi: here’s when

“The safety driver is just there for the first few months to be extra safe. Should be no safety driver by end of year.”

Tesla CEO Elon Musk said today that the company plans to completely eliminate Safety Drivers from its Robotaxi fleet, which differs from the Safety Monitors it uses.

Tesla’s Robotaxi platform utilizes employees in the front passenger seat during city rides in Austin and the driver’s seat of the vehicles during highway operations in Austin, as well as during all rides in the Bay Area.

Musk said the presence of a Safety Driver “is just there for the first few months to be extra safe,” but there are plans to remove them in an effort to remove the crutches the company uses during the early stages of Robotaxi.

The CEO then outlined a timeframe for when it would remove the presence of an employee in the driver’s seat in both Austin and the Bay Area. He said there “should be no safety driver by end of year.”

Having a Safety Driver or Monitor has been a major point of criticism from Robotaxi skeptics and Tesla critics.

However, Tesla has maintained that its priority in the early stages is the safety of riders, which will keep things running; even a single negative incident could derail self-driving efforts as a whole, including those outside of the company.

Tesla executives have said their attitude toward safety is “paranoid,” but for good reason: an accident could set back the progress that it and many other companies, including rivals like Waymo, have made in the past few years.

For now, it might be a point of criticism for some, but it’s smart in the near term. Musk plans for Tesla to have Robotaxi operating for half of the U.S. population by the end of the year as well, so it will be interesting to see if it can maintain these timelines.

Tesla is already giving Robotaxi privileges hours after opening public app

This morning, Tesla launched the app in the Apple Store, giving iOS users the ability to download and join a waitlist in hopes of gaining access.

Tesla is already giving Robotaxi privileges to those who downloaded the app and joined its waitlist just hours after it launched in the United States.

As the Robotaxi platform has been operating in Austin for several months, Tesla is now allowing the general public to download its app and call for a driverless ride in the city.

Tesla Robotaxi makes major expansion with official public app launch

The company previously sent invitations to select media outlets and Tesla influencers, seeking initial feedback on the performance of the Robotaxi platform.

There have been positive reviews, but, as with any Beta program, some mishaps have also occurred, although none have been significant.

As of the writing of this article, the City of Austin only lists one incident involving a Tesla Robotaxi, noting it as a “Safety Concern,” but not an accident or collision.

This morning, Tesla launched the app in the Apple Store, giving iOS users the ability to download and join a waitlist in hopes of gaining access.

Tesla is already granting Robotaxi access to several of those who have downloaded the app and gotten on the waitlist early:

With the launch of the public app, we were not too sure how soon Tesla would be able to initiate bringing more riders into the Robotaxi program. The immediate admittance for some riders just hours after the launch is a big positive and is surely a sign of strength for Tesla and its Robotaxi program.

What many will look for moving forward is the expansion of the geofence, which does not seem like a problem, as Tesla has already managed to do this on three occasions. The most recent expansion has expanded the service area to approximately 190 square miles.

People will also look for evidence of fleet expansion, a concern that has been a concern for many, especially since Tesla has not been completely transparent about it. They have revealed a recent service fleet growth of 50 percent, but there has been no specific number of vehicles mentioned.

Tesla explains why Robotaxis now have safety monitors in the driver’s seat

The update to Austin’s safety monitors became a point of interest among Tesla watchers on social media.

Tesla has provided an explanation about the presence of safety monitors in the driver’s seat of its autonomous Robotaxi units.

The autonomous ride-hailing service is currently being deployed in Austin and the Bay Area, with more cities across the United States expected to gain access to the service later this year.

Safety Monitors

When Tesla launched its initial Robotaxi program in Austin, the company made headlines for operating vehicles without a human in the driver’s seat. Even with this setup, however, Tesla still had safety monitors in the passenger seat of the Robotaxis. The safety monitors, which do not interact with passengers, have been observed to report issues and other behaviors from the autonomous vehicles in real time. 

Safety monitors on the driver’s seat were also employed in the service’s Bay Area rollout, though numerous members of the EV community speculated that this was likely done to meet regulations in California. However, with the expansion of the Austin geofence, riders in Tesla’s Robotaxis observed that the safety monitors in the city have been moved to the driver’s seat as well.

Tesla’s explanation

The update to Austin’s safety monitors became a point of interest among Tesla watchers on social media. Longtime FSD tester Whole Mars Catalog, for one, speculated that the move might be due to Texas’ new regulations for autonomous vehicles, which took effect recently. Interestingly enough, the official Tesla Robotaxi account on X responded to the FSD tester, providing an explanation behind the safety monitor’s move to the driver’s seat.

“Safety monitors are only in the driver’s seat for trips that involve highway driving, as a self-imposed cautious first step toward expanding to highways,” the Tesla Robotaxi account noted.

Tesla has been extremely cautious with its autonomous driving program, particularly with the rollout of its Robotaxi service, which use Unsupervised FSD. This is quite understandable considering the negative media slant that Tesla is consistently subjected to, which could very well result in minute incidents or mistakes by Robotaxis being blown out of proportion.
