According to comments made by US Air Force officials prior to SpaceX’s latest Falcon Heavy launch, the payload assigned to the military’s first fully-certified Falcon Heavy has been swapped with another, although the mission’s late-2020 launch target remains relatively unchanged.

This new information comes on the heels of the June 25th launch of Space Test Program 2 (STP-2), SpaceX’s third successful Falcon Heavy mission and a huge milestone for the rocket’s future as a competitive option for US military launches. Perhaps most importantly, it confirms – barring a surprise launch contract or internal Starlink mission – that Falcon Heavy’s next (and fourth) launch is unlikely to occur until late next year, a gap of at least 15-17 months.

Announced roughly four months after Falcon Heavy’s inaugural February 2018 launch debut, the USAF contracted with SpaceX to launch the ~6350 kg (14,000 lb) AFSPC-52 satellite no earlier than (NET) September 2020. In February 2019, Department of Defense contract announcements revealed that SpaceX had been awarded three military launch contracts, two for the National Reconnaissance Office (NROL-85 & NROL-87) and one for the USAF (AFSPC-44), all tentatively scheduled to launch in 2021.

First reported by Spaceflight Now, Col. Robert Bongiovi – director of the launch enterprise systems directorate at the Air Force’s Space and Missile Systems Center (AFSMC) – recently indicated that AFSPC-44 – not AFSPC-52 – is now scheduled to be the US military’s first post-certification Falcon Heavy launch. 52 and 44 have essentially swapped spots, with AFSPC-44 moving forward to NET Q4 (fall) 2020 while AFSPC-52 has been delayed to NET Q2 (spring) 2021.

The trouble with launch gaps

Although Bongiovi did not explicitly state that AFSPC-44 will be SpaceX’s next Falcon Heavy launch, there are no publicly-disclosed missions set to launch on the rocket in the interim. That could theoretically change, especially if SpaceX has plans to launch the massive rocket in support of an internal Starlink mission or even something more exotic, but the loss of both Block 5 center core B1055 and B1057 means that the company will have to build an entirely new center core.

SpaceX’s Falcon Heavy lead times are far superior to competitor ULA’s Delta IV Heavy production line, but the process of manufacturing new center cores is still quite lengthy. Critically, Falcon Heavy Block 5 center cores require strengthened octawebs, custom interstages, and propellant tanks that are significantly thicker than those used on Falcon 9. For all intents and purposes, a center core is a totally different rocket relative to a Falcon 9 booster, the latter being SpaceX’s primary focus at the company’s assembly line-style Hawthorne factory. It’s theoretically possible for a dedicated Falcon Heavy center core build to be expedited or leapfrogged forward in the production queue, but most long-lead Falcon 9 booster hardware physically cannot be redirected to speed up center core production.

Unless SpaceX was already in the process of building a new center core prior B1057’s unsuccessful landing attempt, it’s safe to assume that the next custom Falcon Heavy booster is unlikely to be completed until early 2020, if not later. In theory, this means that Falcon Heavy could be dormant for no less than 16 months between STP-2 and its next launch. Traditionally, that sort of lengthy gap between launches has been frowned upon by NASA, ULA, and oversight groups like GAO. If a given rocket doesn’t launch for a year or more, it can potentially pose a risk to reliability and raise costs as its production and launch teams have no satisfactory way to fully preserve their technical expertise.

This can be compared to attempting to become an expert at a musical instrument while only having access to said instrument one or two months a year, essentially impossible. In fact, at one point, NASA hoped to require its Space Launch System (SLS) rocket be able to launch no less than once per year, partly motivated by a desire to mitigate some of the deterioration that can follow extremely low launch cadences. Years later, financial constraints and years upon years of delays and budget overruns have made such a cadence effectively impossible for SLS/Orion, but the fact remains that launching a rocket just once every 18-24 months is likely to inflate both costs and risks.

Thankfully, SpaceX’s Falcon Heavy could scarcely be more different than NASA’s SLS and the retired Space Shuttle it derives most of its hardware from. Even if all things are held equal and not flying a Falcon Heavy center core for 16+ months increases risk and cost, center cores are still heavily derived from Falcon 9 booster technology, including plumbing, avionics, attitude control thrusters, Merlin 1D engines, landing legs, and launch facilities.

Furthermore, the center core is just one of five distinct assemblies that make up a given Falcon Heavy. Both side boosters are effectively Falcon 9 Block 5 boosters with nose cones instead of interstages and slight modifications to support booster attachment hardware, while the upper stage and payload fairing are the same for all Falcon launches. In other words, SpaceX’s workforce will continue to build, launch, land, and reuse dozens of Falcon 9 boosters – as well as upper stages payload fairings – between now and Falcon Heavy Flight 4, even if it’s NET Q4 2020. In a worst-case scenario, SpaceX production and launch staff will be unfamiliar and inexperienced with maybe 20% of Falcon Heavy – at least in a very rough sense. Even then, much of that unfamiliarity may still be tempered by the fact that Falcon Heavy center cores share a large amount of commonality with the Falcon 9 first stages SpaceX’s workforce will remain deeply familiar with.

Indeed, Falcon Heavy’s second launch has already demonstrated this to some extent, occurring without issue more than 14 months after the rocket’s inaugural launch. It seems that the only real loss incurred by a ~16-month delay between Flights 3 and 4 will be having to wait another year (or more) to witness Falcon Heavy’s next 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.
