SpaceX, ULA targeting back-to-back geostationary launches

SpaceX and competitor United Launch Alliance (ULA) are on track to launch their Falcon 9 and Atlas V rockets less than 25 hours apart.

Slightly delayed from its initial target of June 27th or 28th, SpaceX confirmed on Tuesday that a Falcon 9 rocket is ready to launch the European-built SES-22 no earlier than (NET) 5:04 pm EDT (21:04 UTC) on Wednesday, June 29th. Just 1.5 miles (2.4 km) to the north of SpaceX’s Cape Canaveral Space Force Station (CCSFS) LC-40 pad, ULA says it’s also on track to launch an Atlas V 541 rocket carrying a batch of rideshare payloads for the US military as early as 6pm EDT (22:00 UTC), Thursday, June 30th.

Both Falcon 9 and Atlas V will be carrying satellites destined for geostationary orbit (GEO), a location roughly 36,000 kilometers (~22,250 mi) above Earth’s surface where spacecraft orbit at the exact same speed as Earth’s rotation. As a result, spacecraft in GEO effectively hover in one spot in the sky to a ground observer, which makes the orbit optimal for some kinds of Earth observation and communications missions. SES-22 is a relatively ordinary commercial GEO communications satellite. ULA’s USSF-12 mission will carry a Wide Field Of View (WFOV) missile launch detection satellite and a mysterious secondary payload called the “USSF-12 Ring,” which ULA says is “a classified mission to demonstrate future technology for the Department of Defense.”

USSF-12’s Atlas V rocket will cost the military roughly $175 million and, like all other Atlas launch vehicles, is fully expendable. The Atlas V booster uses refined kerosene (RP-1) fuel and liquid oxygen oxidizer and is powered by a Russian-built RD-180 engine. The rocket’s Centaur upper stage uses liquid hydrogen (LH2) and LOx propellant and can be powered by one or two US-built RL-10 engines. ULA augments that basic Atlas V variant’s relatively poor performance by adding anywhere from 1-5 solid rocket boosters at its base, which can double the total payload a given Atlas V can launch to most Earth orbits.

Thanks in large part to the greater efficiency of Atlas V’s hydrolox Centaur upper stage, the high-end variants of the rocket with four or five SRBs are capable of launching a significant payload (~3.9 tons or ~8600 lb) directly to GEO, which is where USSF-12 will be heading. Falcon 9 will launch SES-22 to a less challenging geostationary transfer orbit (GTO), which leaves a small portion of the orbit-raising process to the payload.

In return, SpaceX will be able to recover and reuse Falcon 9’s booster and payload fairing and SES will pay more like $50-70 million (and a few extra months) to get its satellite to GEO. It’s quite likely that Falcon 9 would be able to launch a few tons directly to GEO in a fully-expendable configuration, but SpaceX’s Falcon Heavy rocket is able to offer even better direct-to-GEO performance for a similar price by expending one of its three Falcon 9-derived boosters, so the company has never tried to sell that service for Falcon 9.

Tune in below around 4:50 pm EDT (20:50 UTC) to watch SpaceX’s 27th launch of 2022 live. ULA will begin streaming Atlas V’s USSF-12 launch around 24 hours later.

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.
