SpaceX’s newest drone heads to sea for first Falcon 9 booster landing

Published

on

Update: Fresh from the drydock where it was built, SpaceX drone ship A Shortfall of Gravitas has departed Port Canaveral and is headed around 300 km (~190 mi) into the Atlantic Ocean for its first attempted Falcon 9 booster landing and recovery.

Designed to eventually be SpaceX’s first truly autonomous drone ship, it appears that ASOG’s first booster recovery mission(s) will nevertheless be performed like any other – with a tugboat to tow it to and from the landing zone and constant supervision from a team aboard a second support ship. Stay tuned to watch A Shortfall of Gravitas support its first Falcon booster landing as early as 3:37am EDT (07:37 UTC) on Saturday, August 28th.

SpaceX’s newest drone ship will reportedly support its first Falcon 9 booster recovery attempt ever as part of the company’s first launch in almost two months.

As previously discussed on Teslarati, SpaceX last launched on June 30th and is currently scheduled to return to flight (in a sense, at least) no earlier than August 28th, setting up an almost 60-day gap between launches – SpaceX’s longest in almost two years. Now, on top of a few significant milestones for the upgraded Cargo Dragon spacecraft meant to launch later this week, the mission will also mark an important step for the newest addition to SpaceX’s fleet of rocket recovery ships.

Known as A Shortfall of Gravitas (ASOG), that vessel is SpaceX’s third and newest “autonomous spaceport drone ship” and could potentially usher in a new era of rocket recovery for SpaceX according to CEO Elon Musk. Namely, Musk says that ASOG is designed to be the first truly autonomous drone ship. While existing ships Of Course I Still Love You (OCISLY) and Just Read The Instructions (JRTI) are technically autonomous in the sense that they are uncrewed during booster landings at sea, they must be towed to and from their recovery zones and are never far from a crewed support ship with a team of technicians.

Unlike OCISLY and JRTI, Musk says that drone ship ASOG will be truly autonomous in the sense that it’s been designed to propel itself to and from the recovery area without the need for a tugboat. According to Space Offshore, drone ship ASOG unsurprisingly won’t be operated (semi) autonomously on its very first recovery mission. It’s entirely possible that the regulatory side of things (in no way optimized for the operation of autonomous civilian ships) will have to catch up to SpaceX before ASOG is allowed to attempt a Falcon booster recovery with no human intervention.

Combined with the ship’s new ‘Octagrabber’ robot, the third of its kind, it’s not inconceivable that A Shortfall of Gravitas will one day be capable of sailing several hundred kilometers downrange, holding its position during landing, robotically safing and securing a landed booster, and sailing back to port with zero human intervention. Of course, given that things can always go wrong with systems as complex as Falcon boosters and drone ships, SpaceX will almost certainly have technicians tailing ASOG in a support ship for one or several dozen successful missions before ever attempting a fully autonomous recovery without a single human safeguard nearby.

Ultimately, though, that means that SpaceX’s upcoming CRS-23 Cargo Dragon mission could be the first in a long line of careful steps towards a truly autonomous rocket recovery system that might one day save the company millions of dollars per launch.

Verizon, AT&T and T-Mobile are trying to shut Starlink out before FCC vote

AT&T, Verizon and T-Mobile want 290 MHz cut from an FCC satellite plan before Thursday.

Starlink D2D direct to device vs Verizon, AT&T (Concept render by Grok)

AT&T, Verizon and T-Mobile are asking the Federal Communications Commission to pull nearly 300 MHz of spectrum out of a proposal that would let satellite companies like SpaceX offer cell service directly to ordinary phones. The request lands one day before the agency votes on it.

The FCC will vote Thursday, October 29, on a notice of proposed rulemaking that would make an additional 482 MHz available for direct to device service, expanding the number of eligible bands from five to 13, according to the FCC fact sheet. It would also scrap the rule requiring a satellite operator to lease spectrum from carriers, replacing it with a certification that the operator has coexistence agreements in place or holds the terrestrial license itself.

That second path matters for SpaceX. As Teslarati reported earlier this month, SpaceX agreed to buy Grain Management’s nationwide 800 MHz portfolio to turn Starlink Mobile into a full US carrier, adding to the spectrum it already bought from EchoStar.

The carriers want two bands removed, 2.5 GHz and 3.45 GHz, which make up 290 MHz of the 482 MHz on the table. Through industry group CTIA, they argued that about 300 million users depend on those bands and that satellite operations in them are not technically feasible. T-Mobile, which calls 2.5 GHz the foundation of its Ultra Capacity 5G network, said in its own filing that satellite interference could wipe out up to 96% of a cell site’s uplink coverage area and cut uplink speeds by 88% to 99%.

Executives from all three carriers met with FCC staff on October 20, and T-Mobile CEO Srini Gopalan met separately with FCC Chairman Brendan Carr. T-Mobile’s role stands out because it is still SpaceX’s US launch partner for Starlink Mobile. The three carriers have also teamed up on their own satellite joint venture to pool spectrum, a move widely seen as a response to Starlink.

SpaceX is asking for the opposite. In an October 23 filing after meetings with FCC staff and commissioners’ offices, the company asked regulators to add the 902 to 928 MHz band to the proposal. “Doing so now saves time later,” SpaceX wrote. The company also asked the FCC to modernize interference rules and align satellite deployment requirements with those for terrestrial cell networks, saying the goal is to let satellite and ground networks work together so Americans stay connected wherever they are.

The carriers have not been shy about how they view SpaceX as a competitor. On Verizon’s third quarter earnings call Monday, its chief executive said Starlink Mobile “just can’t compete with a terrestrial network” and estimated SpaceX would need four to six years and $300 billion to $500 billion to build a full US carrier network.

Thursday’s vote will not settle which bands survive. Adopting the notice opens a public comment period, with final rules to come later in the proceeding. The FCC already considered and rejected 2.5 GHz for satellite coverage once, in 2024. SpaceX also is not the only satellite player watching: the FCC approved Amazon’s $11.6 billion acquisition of Globalstar on October 27, giving its planned direct to device fleet its own mobile satellite spectrum.

Tesla Semi catches fire in California: what we know

Published

A Tesla Semi caught fire in Hayward, California, which caused both directions of traffic to shut down for hours before being completely reopened early on Wednesday, the California Highway Patrol said.

The fire occurred just after 5:30 local time in Hayward on Tuesday, as the Semi caught fire in the southbound lanes of I-880 before CHP officials made the decision to shut down both lanes of traffic due to potential risks from hazardous chemical smoke.

There were no injuries reported.

The cause of the fire is currently unknown, as neither Tesla nor the CHP have not determined a cause.

However, some images taken before the Semi was completely destroyed by the fire seem to indicate this might have been an older unit, as it appears to be one of the designs that Tesla shipped as part of its pilot program, before revising it and starting mass production just a month ago.

At the time of publication, CHP had not returned our request for a comment for additional details, including the Semi involved and any potential collaboration on an investigation between the CHP and Tesla. We will update this story when we hear back from them.

The southbound lanes were reopened at 3:30 a.m. on Wednesday, with the northbound lanes opening last night a few hours after the fire began. The CHP did state that the lithium batteries were “incredibly difficult to extinguish,” according to NBC Bay Area.

The truck’s driver said that the Semi caught fire, but he did not have an explanation.

An estimated 5,000 to 7,000 semi-truck and large commercial vehicle fires occur on U.S. roadways every year.

Tesla’s ‘Emergency Drive Away’ function gets its first use in the real world

Tesla’s launch of the “Emergency Drive Away” function a few months back offered owners a safe option to evacuate an area if they were in reasonable danger. The function finally got its first use in the real world, but it appears it was by mistake.

A video shared by u/Joshalander in the r/TeslaLounge subreddit recorded the instance from his vehicle and said the incident took place in Austin this past weekend during the city’s F1 Race.

“Was charging around 6 AM this past Sunday in Austin before heading to the F1 race and heard a pop. Looked over and saw the new emergency drive-away feature in action. Genuinely felt bad for the dude when he got out and realized what happened, since he looked exhausted and only seemed to half-read the prompts.”

Emergency Drive Away unlatches the Supercharger connector from the vehicle, but still causes damage to both the car and the Supercharger. Tesla has said that it will cost up to $25,000 in repairs to have everything fixed back to normal.

Additionally, the company said that if it were not used in an emergency situation, the driver of the vehicle who activated the Emergency Drive Away feature would be responsible for all repair costs.

Tesla constitutes the following situations as reasonable justifications for activating the feature:

  • You face an immediate threat to your life or personal safety.
  • You must leave the area immediately.
  • Exiting the vehicle is unsafe.
  • Unplugging the charge connector would unreasonably delay your departure or expose you to a risk to your personal safety.

After using the feature, Tesla requires the driver to schedule Service so the car can be inspected.
