SpaceX Falcon Heavy rocket to launch record-breaking communications satellite
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 leases new 108k-sq ft R&D facility near Fremont Factory
The lease adds to Tesla’s presence near its primary California manufacturing hub as the company continues investing in autonomy and artificial intelligence.
Tesla has expanded its footprint near its Fremont Factory by leasing a 108,000-square-foot R&D facility in the East Bay.
The lease adds to Tesla’s presence near its primary California manufacturing hub as the company continues investing in autonomy and artificial intelligence.
A new Fremont lease
Tesla will occupy the entire building at 45401 Research Ave. in Fremont, as per real estate services firm Colliers. The transaction stands as the second-largest R&D lease of the fourth quarter, trailing only a roughly 115,000-square-foot transaction by Figure AI in San Jose.
As noted in a Silicon Valley Business Journal report, Tesla’s new Fremont lease was completed with landlord Lincoln Property Co., which owns the facility. Colliers stated that Tesla’s Fremont expansion reflects continued demand from established technology companies that are seeking space for engineering, testing, and specialized manufacturing.
Tesla has not disclosed which of its business units will be occupying the building, though Colliers has described the property as suitable for office and R&D functions. Tesla has not issued a comment about its new Fremont lease as of writing.
AI investments
Silicon Valley remains a key region for automakers as vehicles increasingly rely on software, artificial intelligence, and advanced electronics. Erin Keating, senior director of economics and industry insights at Cox Automotive, has stated that Tesla is among the most aggressive auto companies when it comes to software-driven vehicle development.
Other automakers have also expanded their presence in the area. Rivian operates an autonomy and core technology hub in Palo Alto, while GM maintains an AI center of excellence in Mountain View. Toyota is also relocating its software and autonomy unit to a newly upgraded property in Santa Clara.
Despite these expansions, Colliers has noted that Silicon Valley posted nearly 444,000 square feet of net occupancy losses in Q4 2025, pushing overall vacancy to 11.2%.

Tesla winter weather test: How long does it take to melt 8 inches of snow?
In Pennsylvania, we got between 10 and 12 inches of snow over the weekend as a nasty Winter storm ripped through a large portion of the country, bringing snow to some areas and nasty ice storms to others.
I have had a Model Y Performance for the week courtesy of Tesla, which got the car to me last Monday. Today was my last full day with it before I take it back to my local showroom, and with all the accumulation on it, I decided to run a cool little experiment: How long would it take for Tesla’s Defrost feature to melt 8 inches of snow?
Tesla’s Defrost feature is one of the best and most underrated that the car has in its arsenal. While every car out there has a defrost setting, Tesla’s can be activated through the Smartphone App and is one of the better-performing systems in my opinion.
It has come in handy a lot through the Fall and Winter, helping clear up my windshield more efficiently while also clearing up more of the front glass than other cars I’ve owned.
The test was simple: don’t touch any of the ice or snow with my ice scraper, and let the car do all the work, no matter how long it took. Of course, it would be quicker to just clear the ice off manually, but I really wanted to see how long it would take.

Observations
I started this test at around 10:30 a.m. It was still pretty cloudy and cold out, and I knew the latter portion of the test would get some help from the Sun as it was expected to come out around noon, maybe a little bit after.
I cranked it up and set my iPhone up on a tripod, and activated the Time Lapse feature in the Camera settings.
The rest of the test was sitting and waiting.
It didn’t take long to see some difference. In fact, by the 20-minute mark, there was some notable melting of snow and ice along the sides of the windshield near the A Pillar.
However, this test was not one that was “efficient” in any manner; it took about three hours and 40 minutes to get the snow to a point where I would feel comfortable driving out in public. In no way would I do this normally; I simply wanted to see how it would do with a massive accumulation of snow.
It did well, but in the future, I’ll stick to clearing it off manually and using the Defrost setting for clearing up some ice before the gym in the morning.
Check out the video of the test below:

Tesla Robotaxi ride-hailing without a Safety Monitor proves to be difficult
Tesla Robotaxi ride-hailing without a Safety Monitor is proving to be a difficult task, according to some riders who made the journey to Austin to attempt to ride in one of its vehicles that has zero supervision.
Last week, Tesla officially removed Safety Monitors from some — not all — of its Robotaxi vehicles in Austin, Texas, answering skeptics who said the vehicles still needed supervision to operate safely and efficiently.
BREAKING: Tesla launches public Robotaxi rides in Austin with no Safety Monitor
Tesla aimed to remove Safety Monitors before the end of 2025, and it did, but only to company employees. It made the move last week to open the rides to the public, just a couple of weeks late to its original goal, but the accomplishment was impressive, nonetheless.
However, the small number of Robotaxis that are operating without Safety Monitors has proven difficult to hail for a ride. David Moss, who has gained notoriety recently as the person who has traveled over 10,000 miles in his Tesla on Full Self-Driving v14 without any interventions, made it to Austin last week.
He has tried to get a ride in a Safety Monitor-less Robotaxi for the better part of four days, and after 38 attempts, he still has yet to grab one:
Wow just wow!
It’s 8:30PM, 29° out ice storm hailing & Tesla Robotaxi service has turned back on!
Waymo is offline & vast majority of humans are home in the storm
Ride 38 was still supervised but by far most impressive yet pic.twitter.com/1aUnJkcYm8

Tesla said last week that it was rolling out a controlled test of the Safety Monitor-less Robotaxis. Ashok Elluswamy, who heads the AI program at Tesla, confirmed that the company was “starting with a few unsupervised vehicles mixed in with the broader Robotaxi fleet with Safety Monitors,” and that “the ratio will increase over time.”
This is a good strategy that prioritizes safety and keeps the company’s controlled rollout at the forefront of the Robotaxi rollout.
However, it will be interesting to see how quickly the company can scale these completely monitor-less rides. It has proven to be extremely difficult to get one, but that is understandable considering only a handful of the cars in the entire Austin fleet are operating with no supervision within the vehicle.
