SpaceX to revive polar launch trajectory from Florida, a first in 60 years

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.

FCC green lights SpaceX’s move to a showdown with Verizon and AT&T

The FCC advanced plans opening 482 MHz to satellite phone service, boosting SpaceX’s Starlink Mobile.

Published

A hand holds a smartphone displaying the Starlink Mobile app interface showing a strong “Connected – Direct to Cell” signal, with a Starlink satellite beaming connectivity signals down to Earth from orbit. The background features the planet’s night side glowing with city lights against the curve of the atmosphere, set above a scenic twilight landscape.

The Federal Communications Commission voted Thursday to move forward with a proposal that would open an additional 482 MHz of spectrum to satellite service beamed directly to ordinary phones, a step that could widen the road for SpaceX’s Starlink Mobile to compete with the country’s largest wireless carriers.

The commission adopted the notice of proposed rulemaking at its October open meeting in Washington, Reuters reported. The proposal would raise the number of bands eligible for Supplemental Coverage from Space from five to 13, according to the FCC fact sheet. Commissioners also advanced a companion item proposing an auction of 25 MHz in the 1675 to 1695 MHz and 2020 to 2025 MHz bands, which could be used for terrestrial service, direct to device service or both.

Thursday’s vote does not hand any spectrum to SpaceX. It opens a public comment period, and final rules will come later. Under the draft, comments would be due 60 days after the notice is published in the Federal Register. The FCC had not released the adopted text at the time of writing, so it is not yet clear whether any bands were changed before the vote.

That question is where the fight now moves. AT&T, Verizon and T-Mobile, through industry group CTIA, asked the FCC to drop the 2.5 GHz and 3.45 GHz bands, which make up 290 MHz of the 482 MHz on the table, as Teslarati reported ahead of the vote. T-Mobile argued satellite interference could wipe out up to 96% of a cell site’s uplink coverage area. SpaceX asked the commission to go the other way and add the 902 to 928 MHz band.

The rule change that matters most to SpaceX may be a structural one. Today, a satellite operator must lease spectrum from every carrier holding co-channel licenses across an entire region such as the contiguous United States. The proposal would replace that with a certification that the operator has coexistence agreements covering only the areas it plans to serve, or that it holds the terrestrial licenses itself.

SpaceX has spent this year building that second path. It bought EchoStar’s AWS-4 and H-block licenses in a deal worth roughly $17 billion, and earlier this month agreed to acquire Grain Management’s nationwide 800 MHz portfolio, which the company said would pave the way for Starlink to become a major US mobile carrier. The FCC approved SpaceX’s purchase of three unused AWS-3 licenses from Tristar on October 21, and cleared its plan for 15,000 next generation direct to cell satellites on October 6.

The regulator has not always sided with SpaceX. In April, the FCC dismissed a SpaceX petition seeking access to Mobile Satellite Service spectrum held by incumbents, and it rejected 2.5 GHz for satellite coverage when it first adopted the framework in 2024.

The carriers are also building their own defenses. In May, the three companies agreed in principle to form a joint venture pooling spectrum for satellite service, and T-Mobile remains SpaceX’s US launch partner for Starlink Mobile even as it leads the push to keep satellites out of 2.5 GHz. SpaceX President Gwynne Shotwell has said service on SpaceX’s own airwaves is targeted for early 2028.

Tesla’s Roadster appearance at SpaceX has merger watchers talking

Tesla’s next generation Roadster was spotted at SpaceX’s Hawthorne headquarters, two weeks after its unveiling.

Tesla’s next generation Roadster turned up at SpaceX’s headquarters in Hawthorne, California on Wednesday, less than two weeks after the car flew off a ramp at its unveiling in Texas.

Photos shared on X by SpaceX Engineer (@DeannaRiceSPCX) show the new Roadster parked outdoors beside the famed Falcon 9 that stands outside company headquarters at the corner of Crenshaw Boulevard and Jack Northrop Avenue. Rocket B1019 was the first orbital-class booster ever to land after a launch on December 21, 2015 after it sent 11 Orbcomm satellites to orbit and then flew back to Landing Zone 1 at Cape Canaveral, which would be the first landing in what became SpaceX’s reusable rocket program. SpaceX chose not to fly it again. After a test fire in Florida, the booster was shipped to Hawthorne and raised upright as a permanent monument in August 2016, as Teslarati reported at the time. Putting the Roadster, which flies on SpaceX cold gas thrusters, next to the rocket that started SpaceX’s landings is symbolic in itself.

The Thrust and Rocket versions of the Roadster use cold gas thrusters fed by composite overwrapped pressure vessels, the same type of tank SpaceX flies on Falcon 9, and Elon Musk described the car as the work of Tesla and SpaceX engineers working together. Tesla lists 0 to 60 mph in under 0.9 seconds for Thrust and under 0.59 seconds for Rocket, while the base Performance model relies on a fan and ground sealing system for grip, as Teslarati detailed in its breakdown of the three Roadster configurations.

Tesla has kept the car in the spotlight since the October 15 event near Waco. Last week, the company posted a video of the Roadster’s fighter jet inspired cockpit, including a Track Mode screen with a “Thruster · 5,500 PSI” readout, which we covered in our look at the Roadster’s center display. Musk also said owners will be able to ask the car to perform the stunts autonomously, and promised a looping track at Tesla’s Texas headquarters.

The visit comes as special committees at Tesla and SpaceX weigh a possible merger, a step Musk confirmed on SpaceX’s third quarter earnings call. The Roadster, built on SpaceX hardware, has become one of the clearest examples of the two companies already building products together.

Musk said at the unveiling that Roadster production will begin in 2028. Reservations are open with a $50,000 payment, Thrust is listed as a limited release and Rocket is invite only. Tesla says the car is not approved for public road use.

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.

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.
