SpaceX Falcon Heavy rocket to launch record-breaking communications satellite

Published

A report on the latest in a long line of SpaceX launches significantly delayed by customer payload readiness has been updated to confirm that the satellite in question will launch on Falcon Heavy, not Falcon 9.

Hughes revealed that it had selected SpaceX to launch its Maxar-built Jupiter-3 geostationary communications satellite during an industry conference on March 21st, 2022. At the time, Hughes stated that the satellite was on track to launch in the fourth quarter of 2022, a refinement but also a delay from earlier plans to launch sometime in H2 2022. Just six weeks later, manufacturer Maxar reported that the completion of Jupiter 3 – like many other Maxar spacecraft – had been delayed, pushing its launch to no earlier than (NET) “early 2023.”

At the same time, Maxar revealed that Jupiter 3 – also known as Echostar 24 – was expected to weigh around 9.2 metric tons (~20,300 lb) at liftoff when that launch finally happens. That figure immediately raised some questions about which SpaceX rocket Hughes or Maxar had chosen to launch the immense satellite.

Earlier on, regulatory documents revealed that Jupiter 3 would have a dry weight of 5817 kilograms (~12,825 lb). In July 2018, SpaceX broke the record for heaviest commercial geostationary satellite launch when a Falcon 9 rocket successfully delivered Telesat’s 7076-kilogram (15,600 lb) Telstar 19V to geostationary transfer orbit (GTO). To account for the satellite’s weight and still allow for Falcon 9 booster recovery, SpaceX launched Telstar 19V to a transfer orbit with its apogee (high point) well below geostationary orbit, meaning that the satellite had to do more of the work of orbit-raising. In other words, it wasn’t inconceivable that Jupiter 3 would also be launched to a low (subsynchronous) GTO on a recoverable Falcon 9.

However, in hindsight, Jupiter 3’s 5.8-ton dry mass should have already made it clear that that was unlikely. Telstar 19V, for example, had a reported dry mass of just over 3 tons (~6700 lb), meaning that more than half its wet mass was fuel for orbit-raising and maneuvers. In more normal cases, large geostationary satellites tend to launch with an extra 50-80% of their dry mass in fuel, not ~130%. Even at the low end of large geostationary satellites, Jupiter 3 was likely to have a launch mass of well over 8 tons.

At 9.2 tons, Jupiter 3 will leapfrog the world record for the largest commercial geostationary satellite ever launched by 30%. Barring the possibility of secret military spacecraft, it will likely be the heaviest spacecraft of any kind to reach geostationary orbit 35,785 km (22,236 miles) above Earth’s surface. More importantly, Jupiter 3 may also have the heaviest dry mass of any spacecraft to reach GEO, meaning that the actual hardware it will use to fill its role as a communications hub will also be exceptionally large and powerful. Jupiter 3 will deliver a maximum bandwidth of 500 gigabits per second.

With its exceptional heft, a recoverable Falcon 9 launch may have only been able to loft Jupiter 3 around half the way to GTO from low Earth orbit (LEO). It was little surprise, then, to learn that Hughes and Maxar had actually selected SpaceX’s far more capable Falcon Heavy rocket to launch the satellite. Even with full recovery of all three Falcon Heavy first-stage boosters, there’s a good chance that the rocket would be able to launch Jupiter 3 most of or all the way to a nominal geostationary transfer orbit. If the center core is expended and the side boosters land at sea, Falcon Heavy would likely be able to launch Jupiter 3 to a highly supersynchronous GTO, meaning that the spacecraft’s apogee would end up well above GEO. For example, on Falcon Heavy’s Block 5 launch debut, the rocket sent the ~6.5-ton (~14,250 lb) Arabsat 6A communications satellite to a GTO with an apogee of almost 90,000 kilometers (~56,000 mi), shaving about 20% off of the satellite’s orbit-raising workload.

Falcon Heavy’s Jupiter 3 mission won’t beat the record for total payload to GTO in a single launch, held by Arianespace’s Ariane 5 rocket after a 2021 mission to GTO launched two communications satellites weighing 10.27t, but it will be just one ton shy.

Jupiter 3 is the 10th mission firmly scheduled to launch on SpaceX’s Falcon Heavy rocket between now and 2025.

Tesla Supercharger Diner food menu gets a sneak peek as construction closes out

What are you ordering at the Tesla Diner?

The Tesla Supercharger Diner in Los Angeles is nearing completion as construction appears to be winding down significantly. However, the more minor details, such as what the company will serve at its 50s-style diner for food, are starting to be revealed.

Tesla’s Supercharger Diner is set to open soon, seven years after CEO Elon Musk first drafted the idea in a post on X in 2018. Musk has largely come through on most of what he envisioned for the project: the diner, the massive movie screens, and the intended vibe are all present, thanks to the aerial and ground footage shared on social media.

We already know the Diner will be open 24/7, based on decals placed on the front door of the restaurant that were shared earlier this week. We assume that Tesla Optimus will come into play for these long and uninterrupted hours.

The Tesla Diner is basically finished—here’s what it looks like

As far as the food, Tesla does have an email also printed on the front door of the Diner, but we did not receive any response back (yet) about what cuisine it will be offering. We figured it would be nothing fancy and it would be typical diner staples: burgers, fries, wings, milkshakes, etc.

According to pictures taken by @Tesla_lighting_, which were shared by Not a Tesla App, the food will be just that: quick and affordable meals that diners do well. It’s nothing crazy, just typical staples you’d find at any diner, just with a Tesla twist:

As the food menu is finalized, we will be sure to share any details Tesla provides, including a full list of what will be served and its prices.

Additionally, the entire property appears to be nearing its final construction stages, and it seems it may even be nearing completion. The movie screens are already up and showing videos of things like SpaceX launches.

There are many cars already using the Superchargers at the restaurant, and employees inside the facility look to be putting the finishing touches on the interior.

It’s almost reminiscent of a Tesla version of a Buc-ee’s, a southern staple convenience store that offers much more than a traditional gas station. Of course, Tesla’s version is futuristic and more catered to the company’s image, but the idea is the same.

It’s a one-stop shop for anything you’d need to recharge as a Tesla owner. Los Angeles building permits have not yet revealed the date for the restaurant’s initial operation, but Tesla may have its eye on a target date that will likely be announced during next week’s Earnings Call.

Tesla’s longer Model Y did not scale back requests for this vehicle type from fans

Tesla fans are happy with the new Model Y, but they’re still vocal about the need for something else.

Tesla launched a slightly longer version of the Model Y all-electric crossover in China, and with it being extremely likely that the vehicle will make its way to other markets, including the United States, fans are still looking for something more.

The new Model Y L in China boasts a slightly larger wheelbase than its original version, giving slightly more interior room with a sixth seat, thanks to a third row.

Tesla exec hints at useful and potentially killer Model Y L feature

Tesla has said throughout the past year that it would focus on developing its affordable, compact models, which were set to begin production in the first half of the year. The company has not indicated whether it met that timeline or not, but many are hoping to see unveilings of those designs potentially during the Q3 earnings call.

However, the modifications to the Model Y, which have not yet been officially announced for any markets outside of China, still don’t seem to be what owners and fans are looking forward to. Instead, they are hoping for something larger.

A few months ago, I reported on the overall consensus within the Tesla community that the company needs a full-size SUV, minivan, or even a cargo van that would be ideal for camping or business use.

Tesla is missing one type of vehicle in its lineup and fans want it fast

That mentality still seems very present amongst fans and owners, who state that a full-size SUV with enough seating for a larger family, more capability in terms of cargo space for camping or business operation, and something to compete with gas cars like the Chevrolet Tahoe, Ford Expedition, or electric ones like the Volkswagen ID.BUZZ.

We asked the question on X, and Tesla fans were nearly unanimously in support of a larger SUV or minivan-type vehicle for the company’s lineup:

Here’s what some of the respondents said:

Tesla is certainly aware that many of its owners would like the company to develop something larger that competes with the large SUVs on the market.

However, it has not stated that anything like that is in the current plans for future vehicles, as it has made a concerted effort to develop Robotaxi alongside the affordable, compact models that it claims are in development.

It has already unveiled the Robovan, a people-mover that can seat up to 20 passengers in a lounge-like interior.

The Robovan will be completely driverless, so it’s unlikely we will see it before the release of a fully autonomous Full Self-Driving suite from Tesla.

Tesla has launched its first-ever Virtual Power Plant program in the United Kingdom. This feature enables users of solar panels and energy storage systems to sell their excess energy back to the grid.

Tesla is utilizing Octopus Energy, a British renewable energy company that operates in multiple markets, including the UK, France, Germany, Italy, Spain, Australia, Japan, New Zealand, and the United States, as the provider for the VPP launch in the region.

The company states that those who enroll in the program can earn up to £300 per month.

Tesla has operated several VPP programs worldwide, most notably in California, Texas, Connecticut, and the U.S. territory of Puerto Rico. This is not the first time Tesla has operated a VPP outside the United States, as there are programs in Australia, Japan, and New Zealand.

This is its first in the UK:

Tesla is not the only company that is working with Octopus Energy in the UK for the VPP, as it joins SolarEdge, GivEnergy, and Enphase as other companies that utilize the Octopus platform for their project operations.

It has been six years since Tesla launched its first VPP, as it started its first in Australia back in 2019. In 2024, Tesla paid out over $10 million to those participating in the program.

Tesla VPP program in California hits new capacity milestone

Participating in the VPP program that Tesla offers not only provides enrolled individuals with the opportunity to earn money, but it also contributes to grid stabilization by supporting local energy grids.
