SpaceX Starlink satellite constellation aims to become world’s largest after next launch

Published

on

In a sign of things to come next year, SpaceX’s next – and third – 60-satellite Starlink launch is officially on the books, and – if all goes as planned – could make the company the proud owner of the world’s largest operational satellite constellation.

On May 24th, Falcon 9 lifted off for the first time ever on a dedicated Starlink launch, placing 60 ‘v0.9’ prototype satellites in Low Earth Orbit (LEO), where they deployed solar arrays and fired up their own electric krypton thrusters to reach their operational ~550 km (340 mi) orbits. Of those 60 prototypes, several were intentionally deorbited while another handful suffered unintended failures, while 51 (85%) ultimately reached that final orbit and began operations.

Previously expected in mid-October, unspecified delays pushed SpaceX’s next Starlink launch – deemed Starlink-1, the first launch of ‘v1.0’ satellites – into November. On November 11th, Falcon 9 B1048 and a flight-proven payload fairing lifted off with 60 more Starlink satellites, also marking the first time a Falcon 9 booster completed four orbital launches and the first operational reuse of a recovered fairing. Upgraded with four times the overall bandwidth, improved structures, new Ka-band antennas, and more steerable ‘beams’ on each of those antennas, those 60 Starlink v1.0 satellites rapidly came online and began raising their orbits.

This time around, SpaceX received FCC approval to test satellites at a substantially lower altitude of ~350 km (220 mi) and launched to a parking orbit of just 280 km (175 mi), ensuring that any debris or failed spacecraft will reenter Earth’s atmosphere in just a matter of months while also completely avoiding added risk to the International Space Station (ISS) (~400 km). After a brisk ten or so days of active propulsion, 55 of those 60 satellites have raised their orbits to ~350 km, while ~20 of those 55 appear to be aiming for a final altitude somewhat higher, likely the start of a separate orbital plane.

The moment that Starlink-1 satellites began to arrive and stabilize at their 350-km operational orbits, nearly all of SpaceX’s 50 operational v0.9 satellites began lowering their orbits, potentially signaling a move down to Starlink-1’s operational altitude, or even an intentional deorbit of the entire prototype tranche (far less likely).

From nothing to #1

The same day that several dozen Starlink-1 satellites finished the climb up to their operational orbits, SpaceX announced media accreditation for its next Starlink launch, presumed to be Starlink-2. According to SpaceX, the mission is targeted for the last two weeks of December 2019, a schedule that will tighten as it gets closer. Previously expected to launch in early November, as few as two weeks after Starlink-1, Starlink-2 has suffered similar delays but still appears to be on track for 2019.

It’s assumed that Starlink-2 – like both dedicated missions preceding it – will launch 60 Starlink satellites. If that is, in fact, the case, the mission could mark a surprising but fully-expected milestone: with >170 functional satellites in orbit, SpaceX might become the proud owner of the world’s largest operational satellite constellation. Excluding two Tintin prototypes launched in February 2018 and 8 failed Starlink v0.9 spacecraft, a perfect Starlink-2 launch would raise SpaceX’s operational constellation to 172 satellites.

The only satellite operator anywhere close to those numbers is Planet Labs, an Earth observation analytics and satellite production company that has launched >400 satellites in its lifetime. Of those ~400 spacecraft, it’s believed that ~150 were operational as of October 2019 and Planet has another 12 Dove observation satellites scheduled to launch on November 27th. In simple terms, this means that SpaceX may become the world’s largest satellite operator after Starlink-2 and it all but guarantees that that will be the case after Starlink-3, a mission that will likely follow just weeks later.

Once SpaceX passes that milestone, it’s all but guaranteed that Starlink will retain the title of world’s largest satellite constellation for the indefinite future. According to SpaceX COO and President Gwynne Shotwell, as many as 24 Starlink launches are planned for 2020, and SpaceX’s burgeoning Washington-state satellite factory may soon be capable of supporting the unprecedented volume of production such a cadence will require. Even assuming rocky development, it’s hard to picture SpaceX’s next-generation Starship rocket taking more than two additional years to be ready for routine orbital missions to LEO, each of which should be able to place 400 Starlink satellites in orbit.

OneWeb is by far the closest thing SpaceX has to a serious Starlink competitor and its first operational launch of ~30 satellites has recently suffered delays, moving from December to late-January or February 2020. Roughly monthly launches (each with ~30 satellites) will nominally follow that first launch. After Starlink-2 or Starlink-3, the only conceivable ways that SpaceX could ever lose the title of world’s largest satellite operator would require catastrophic failure(s) grounding Falcon 9 and/or Starship for >1 year or outright bankruptcy and liquidation, neither of which seem particularly likely.

SpaceX set to launch astronauts and a classified Falcon Heavy mission on the same day

SpaceX plans three launches Thursday, including Crew-13 astronauts and Falcon Heavy’s first classified NRO mission.

SpaceX is lining up one of the busiest single days in its history, and the company offered a preview on Wednesday morning with a simple post on X: “Sunrise at pad 40.” The video and photos show Falcon 9 standing at Space Launch Complex 40 at Cape Canaveral, roughly a day before it is scheduled to carry four astronauts to the International Space Station.

That launch is only the first of three SpaceX missions planned for Thursday, October 1, across both coasts.

Crew-13 is targeting liftoff at 11:10 a.m. ET, with a backup opportunity Friday at 10:47 a.m. ET. NASA astronaut Jessica Watkins will command the mission, with NASA’s Luke Delaney as pilot and Canadian Space Agency astronaut Joshua Kutryk and Roscosmos cosmonaut Sergey Teteryatnikov serving as mission specialists. According to NASA, Dragon is set to dock with the forward port of the station’s Harmony module around 8 p.m. ET, less than nine hours after launch. Watkins is the only member of the crew who has flown before, and Kutryk will become the first Canadian to reach orbit through NASA’s Commercial Crew Program.

The Falcon 9 booster is flying for the third time after supporting Crew-12 and a Starlink mission, and it will attempt a landing at Landing Zone 40 beside the pad. That site made its debut in February when the Crew-12 booster touched down there, as Teslarati reported at the time. Crew-13 will relieve the Crew-12 astronauts, who have been aboard the station since the middle of February.

On the West Coast, another Falcon 9 is scheduled to lift off from Vandenberg Space Force Base in a window running from 2:18 to 3:16 p.m. ET, a flight NASASpaceflight lists as a Transporter rideshare mission.

The day is set to close at 11:53 p.m. ET, when Falcon Heavy launches from Launch Complex 39A with NROL-97, the first National Reconnaissance Office payload ever to fly on the rocket. SpaceX rolled the vehicle out to the pad Tuesday night. Its two side boosters, which previously flew GOES-U, ViaSat-3 F3 and NASA’s Roman Space Telescope, will return to Landing Zones 1 and 2, while a new center core will be expended in the Atlantic. The Roman launch took place on August 30, so NROL-97 will come barely a month later as Falcon Heavy’s third flight of 2026 and 14th overall.

NASA taps SpaceX to launch the telescope that could unlock new worlds

If all three Florida boosters land as planned, it would be the first time the Space Coast has seen landings at LZ-40, LZ-1 and LZ-2 on the same day, according to the Orlando Sentinel, which has warned residents in Brevard, Orange and Volusia counties that more than one sonic boom is possible.

The schedule arrives just three days after Starship reached orbit for the first time on Flight 14 from Starbase, Texas, deploying 26 Starlink V3 satellites. If Thursday’s missions stay on time, SpaceX will have flown Starship, Falcon 9 and Falcon Heavy from four different pads in about four days.

Crew-13 is also the start of a longer run for Dragon. NASA recently added Crew-15, Crew-16 and Crew-17 to SpaceX’s contract in a $946 million modification, keeping Dragon as the agency’s only operational ride to the station while Boeing’s Starliner remains grounded.

Tesla Cybercab and Semi have more in common than you might think

Published

on

Although the two vehicles are built for completely different use cases, Tesla utilized engineering expertise while developing both the Cybercab and Semi to build a thermal architecture that would fit both vehicles. Of course, with some slight revisions.

The development was noted by Lars Moravy and Dan Priestley last week at Tesla’s Semi Handover event in Sparks, Nevada, where the company showed off its dedicated production facility for the Class 8 truck.

Tesla’s decision to develop one thermal architecture for both the Cybercab and Semi is one of the more revealing engineering choices in the company’s 2026 lineup:

“We designed it at the same time we designed the Cybercab and we said okay we’re going to take our most efficient vehicle and our biggest vehicle and we’re going to take one thermal system and make it work for both.”

Core parts, meaning the compressor, pumps, and heat exchangers, are shared, with only modest changes to cooling-loop sizing and a larger radiator on the truck. The result, they said, is a compressor and thermal stack already proven across millions of miles, delivering “reliability from day one.”

Priestley also highlighted a practical payoff of the indirect design:

“There’s no AC lines, there’s no refrigerant lines…It comes from the factory fully charged, sealed with refrigerant, and it just exchanges coolant. It doesn’t actually run refrigerant up to the front of the vehicle.”

This eliminates potentially leak-prone plumbing that would otherwise require hands-on service, reducing overall uptime and potentially cutting into business margins. The megamanifold runs cabin HVAC and every powertrain heating and cooling loop at once, recapturing waste heat from motors and the battery instead of dumping it the way a diesel engine does.

The approach is just the latest chapter in a continuing story of stretching thermal solutions across wildly different vehicles. Model Y’s Octovalve evolved into the Super Manifold used on Cybertruck, and later Model S/X refreshes. Cybercab then introduced Supermanifold V3, which Tesla says is 80 percent automated to build and 38 percent more efficient than typical automotive thermal systems.

Tesla has done the same with the 4680 cells, both being utilized in the Cybertruck and Semi, and with heat-pump compressors that Priestley noted were already common across the passenger-car fleet.

Concurrent development of crucial vehicle elements buys scale and reliability that a truck-only thermal system could not match. High-volume passenger car parts are cheaper and more accessible, which can give fleets a sealed, low-maintenance loop of operation from their first day of operation.

For owners and operators, that translates into less energy spent on cabin heat in the colder months, fewer refrigerant-related repairs, and a thermal architecture already stress-tested at passenger-car volumes before the first high-volume Semi left the lines in Nevada.

Elon Musk weather update tips Tesla Roadster speculation into Plaid Mode

Published

Tesla CEO Elon Musk certainly tipped off some details of the Tesla Roadster event with a broadening of information regarding the company’s decision to delay the unveiling for two weeks.

For years, people have speculated about what the Roadster will be capable of. While there have been plenty of things said about what it *could* do, we have not seen or been told by Tesla what it will actually be capable of.

However, over the past few days, Tesla’s weather updates have truly pushed the speculation into Plaid Mode, basically all but confirming the car will have some sort of aerial capability — whether that would be hovering or fully flying remains to be seen — but it definitely seems that it will be able to leave the ground intentionally.

“Because this event can only be held outdoors…”

Tesla posted on Monday that it would delay the Roadster event until October 15, and it indicated that it had to do this because the event “can only be held outdoors.”

With the potential SpaceX collaboration to develop cold-gas thrusters that will help the vehicle go airborne, doing this indoors is probably not a safe, or even plausible, possibility.

FAA Airspace Restriction

The FAA gave Tesla a Temporary Flight Restriction (TFR) for 10,000 feet above ground level, much higher than the typical 2,000-foot restrictions that are usually placed at SpaceX’s McGregor, Texas site.

Tesla Roadster event requires restricted airspace, and the FAA obliges

Some have said that this massive increase is due to Tesla’s need to restrict unauthorized drone use for spying on the event.

Elon Admits High Winds

“Due to high winds, the new Roadster demo is postponed by 2 weeks,” Musk said in a post on X yesterday.

A reply reading, “What’s strong wind got to do with a car demo with four grounded wheels?” was directly below Musk’s post, satirically and sarcastically probing for more details.

All signs are pointing toward an aerial demonstration for the Roadster.
