SpaceX is set to make history by returning southern trajectory polar corridor launches to Florida’s Space Coast with the launch of the Argentine SAOCOM-1B radar observation satellite later this month. Tentatively set to get off the ground no earlier than Saturday, July 25 the SAOCOM-1B mission has suffered delays ranging from hardware processing and integration to international launch team travel restrictions as a result of the global coronavirus pandemic.

In late February 2020, the SAOCOM-1B satellite departed Argentina aboard a Russian Antonov AN 124 cargo aircraft and arrived at the Shuttle Landing Facility in Cape Canaveral, Florida. It was expected that launch and processing teams from Argentina’s National Commission for Space Activities (CONAE) would quickly follow to meet a March launch timeline. However, international travel restrictions imposed by the Argentine government in early March meant that SpaceX would have to wait an indeterminant amount of time to attempt the historic polar launch from Florida. As a result, the satellite was put into storage in one of SpaceX’s satellite processing facilities in Florida to await the arrival of its launch team.

A change in launch plans

The SAOCOM-1B satellite was initially thought to launch from Vandenberg Air Force Base (VAFB) in California just as its twin predecessor, the SAOCOM-1A satellite did in October of 2018. At the time VAFB was the only US-based launch site used for polar orbit launch corridor services. However, Cape Canaveral Air Force Station had previously announced the option to re-open a southern polar orbit launch corridor from Florida in 2017, a launch trajectory that hadn’t been used in over half a century.

The option of polar trajectory launches from Florida increased SpaceX’s capacity to streamline its launch manifest to the company’s dual launchpad locations on Florida’s East Coast. In 2019, as reported by Michael Baylor of NASASpaceflight.com, SpaceX formally requested to move the launch of the SAOCOM-1B satellite from VAFB to Florida utilizing a southern, coast-hugging dog-leg trajectory over Cuba to a final polar orbital inclination.

The SAOCOM-1B satellite will join its L-Band, synthetic-aperture radar (SAR) SAOCOM-1A sister satellite in a sun-synchronous orbit (SSO) – essentially an orbit over the poles of the planet that allows the solar arrays of the satellite to be in sunlight at any given time. The satellites operate in SSO and use L-Band and synthetic-aperture radar to create two-dimensional, all-weather Earth observation imagery to assist in global disaster-monitoring efforts. The sister satellites will also work in conjunction with a constellation of four Italian satellites already in orbit operated by COSMO-SkyMed.

Return to operational status

Following the easement of certain international travel restrictions in mid-July, a slim crew of 18 team members from CONAE and SAOCOM-1B satellite manufacturer INVstigacion APlicada (INVAP) was permitted to travel to Florida. The team members tested negatively for the COVID-19 virus prior to commercially traveling to Florida from Argentina, as well as, after their arrival at Miami International Airport. The team observed a two-week period of quarantine prior to traveling to SpaceX facilities at Cape Canaveral Air Force Station to begin pre-operational tasks.

On Monday, July 13 the team was able to get to work on launch campaign tasks with the satellite that had endured months of storage. The team ensured the health of the satellite and completed a full launch day simulation managed remotely from locations in Florida and Argentina. Following a successful run through and check of the satellite’s operational status, the launch campaign has just a few remaining steps before rocketing SpaceX into the history books once again.

SpaceX and CONAE teams will work together to safely encapsulate the satellite inside of a protective Falcon 9 payload fairing and mate the payload with the first stage Falcon 9 booster. Furthermore, the teams will complete a joint integration test of the payload and launch vehicle before finally transporting it to the launch pad.

The SpaceX launch manifest has recently undergone some schedule shuffling potentially leaving the SAOCOM-1B mission to be third in line behind the launch of the South Korean ANASIS-II military communications satellite and the delayed Starlink-9 mission. However, earlier in the week, the Starlink-9 booster was lowered from launch position at LC-39A and returned to the horizontal integration facility following a scrubbed launch attempt with SpaceX citing that more time was necessary to perform final check-outs. This most likely suggests that SpaceX plans to push the SAOCOM-1B mission ahead of Starlink-9 in the launch manifest.

According to CONAE, the SAOCOM-1B mission launch window extends from Saturday, July 25 to Thursday, July 30 with a targeted liftoff at approximately 7:19 p.m. EDT (2319 GMT) from SLC-40.

Elon Musk fires back after Wikipedia co-founder claims neutrality and dubs Grokipedia “ridiculous”

Musk’s response to Wales’ comments, which were posted on social media platform X, was short and direct: “Famous last words.”

Elon Musk fired back at Wikipedia co-founder Jimmy Wales after the longtime online encyclopedia leader dismissed xAI’s new AI-powered alternative, Grokipedia, as a “ridiculous” idea that is bound to fail.

Musk’s response to Wales’ comments, which were posted on social media platform X, was short and direct: “Famous last words.”

Wales made the comments while answering questions about Wikipedia’s neutrality. According to Wales, Wikipedia prides itself on neutrality. 

“One of our core values at Wikipedia is neutrality. A neutral point of view is non-negotiable. It’s in the community, unquestioned… The idea that we’ve become somehow ‘Wokepidea’ is just not true,” Wales said.

When asked about potential competition from Grokipedia, Wales downplayed the situation. “There is no competition. I don’t know if anyone uses Grokipedia. I think it is a ridiculous idea that will never work,” Wales wrote.

After Grokipedia went live, Larry Sanger, also a co-founder of Wikipedia, wrote on X that his initial impression of the AI-powered Wikipedia alternative was “very OK.”

“My initial impression, looking at my own article and poking around here and there, is that Grokipedia is very OK. The jury’s still out as to whether it’s actually better than Wikipedia. But at this point I would have to say ‘maybe!’” Sanger stated.

Musk responded to Sanger’s assessment by saying it was “accurate.” In a separate post, he added that even in its V0.1 form, Grokipedia was already better than Wikipedia.

During a past appearance on the Tucker Carlson Show, Sanger argued that Wikipedia has drifted from its original vision, citing concerns about how its “Reliable sources/Perennial sources” framework categorizes publications by perceived credibility. As per Sanger, Wikipedia’s “Reliable sources/Perennial sources” list leans heavily left, with conservative publications getting effectively blacklisted in favor of their more liberal counterparts.

As of writing, Grokipedia has reportedly surpassed 80% of English Wikipedia’s article count.

Tesla Sweden appeals after grid company refuses to restore existing Supercharger due to union strike

The charging site was previously functioning before it was temporarily disconnected in April last year for electrical safety reasons.

Tesla Sweden is seeking regulatory intervention after a Swedish power grid company refused to reconnect an already operational Supercharger station in Åre due to ongoing union sympathy actions.

The charging site was previously functioning before it was temporarily disconnected in April last year for electrical safety reasons. A temporary construction power cabinet supplying the station had fallen over, described by Tesla as occurring “under unclear circumstances.” The power was then cut at the request of Tesla’s installation contractor to allow safe repair work.

While the safety issue was resolved, the station has not been brought back online. Stefan Sedin, CEO of Jämtkraft elnät, told Dagens Arbete (DA) that power will not be restored to the existing Supercharger station as long as the electric vehicle maker’s union issues are ongoing. 

“One of our installers noticed that the construction power had been backed up and was on the ground. We asked Tesla to fix the system, and their installation company in turn asked us to cut the power so that they could do the work safely.

“When everything was restored, the question arose: ‘Wait a minute, can we reconnect the station to the electricity grid? Or what does the notice actually say?’ We consulted with our employer organization, who were clear that as long as sympathy measures are in place, we cannot reconnect this facility,” Sedin said. 

The union’s sympathy actions, which began in March 2024, apply to work involving “planning, preparation, new connections, grid expansion, service, maintenance and repairs” of Tesla’s charging infrastructure in Sweden.

Tesla Sweden has argued that reconnecting an existing facility is not equivalent to establishing a new grid connection. In a filing to the Swedish Energy Market Inspectorate, the company stated that reconnecting the installation “is therefore not covered by the sympathy measures and cannot therefore constitute a reason for not reconnecting the facility to the electricity grid.”

Sedin, for his part, noted that Tesla’s issue with the Supercharger is quite unique. And while Jämtkraft elnät itself has no issue with Tesla, its actions are based on the unions’ sympathy measures against the electric vehicle maker.

“This is absolutely the first time that I have been involved in matters relating to union conflicts or sympathy measures. That is why we have relied entirely on the assessment of our employer organization. This is not something that we have made any decisions about ourselves at all. 

“It is not that Jämtkraft elnät has a conflict with Tesla, but our actions are based on these sympathy measures. Should it turn out that we have made an incorrect assessment, we will correct ourselves. It is no more difficult than that for us,” the executive said.

Recent commentary on social media has highlighted what could very well prove to be The Boring Company’s real disruption.

The analysis was shared by tech watcher Aakash Gupta on social media platform X, where he argued that the real story behind the tunneling startup’s Nashville tunnel project is the company’s targeted $25 million per mile construction cost.

According to Gupta’s breakdown, Nashville’s 2018 light rail proposal was priced at roughly $200 million per mile. New York’s East Side Access project reportedly cost about $3.5 billion per mile, while Los Angeles Metro expansion projects have approached $1 billion per mile.

By comparison, The Boring Company has stated it can construct 13 miles of twin tunnels in the Music City Loop for between $240 million and $300 million total. That implies a cost near $25 million per mile, or roughly a 95% reduction from industry averages cited in the post.

Several technical departures from conventional tunneling allow the Boring Company to lower its costs, from its smaller 12-foot diameter tunnels to its fully electric Prufrock machines that are designed to mine continuously with no personnel inside the tunnel and their capability to “porpoise” for easy launch and retrieval.

Tesla and Space CEO Elon Musk responded to the post on X, stating simply that “Tunnels are so underrated.”

The Boring Company has seen some momentum as of late, with the company recently signing a construction contract in Dubai and the Universal Orlando Loop progressing. Recent reports have also pointed to tunnels potentially being constructed to solve traffic congestion issues near the Giga Nevada area. 

While The Boring Company’s tunnels have so far been used for Loop systems publicly for now, Elon Musk recently noted that the tunneling startup’s underground passages would not be limited only to ride-hailing vehicles.

In a reply to a post on X which discussed the specifications of the Music City Loop, Musk clarified that “any fully autonomous electric cars can use the tunnels.” This suggests that vehicles potentially running systems like FSD Supervised, even if they are not Teslas, could be used in systems like the Music City Loop in the future.
