SpaceX expends third Falcon booster in one month

Published

SpaceX has expended a Falcon booster for the third time this month, breaking an odd internal record for a company famous for reusable rockets.

Demonstrating why SpaceX often attempts to launch even when weather forecasts predict a 10% chance of favorable conditions, Falcon 9’s second launch attempt of the day went off without a hitch after the first attempt – Cargo Dragon’s CRS-26 space station resupply mission – was scrubbed by weather six hours prior. Flying for the eleventh and final time, Falcon 9 booster B1049 lifted off from SpaceX’s Cape Canaveral Space Force Station (CCSFS) LC-40 pad at 9:57 pm EST (02:57 UTC) carrying French communications provider Eutelsat’s Eutelsat 10B satellite.

B1049 – the oldest booster in SpaceX’s fleet – took advantage of the extra performance enabled by removing landing hardware and propellant reserves and reached a peak velocity of 2.75 kilometers per second (~6150 mph) before separating from Falcon 9’s upper stage. Lacking the propellant needed to slow down, B1049 was likely destroyed when it reentered Earth’s atmosphere. The upper stage performed nominally, entering a parking orbit around 300 kilometers (200 mi) before igniting for a second time to boost the 5.5-ton (~12,000 lb) Eutelsat 10B satellite into a geosynchronous transfer orbit (GTO).

Thanks to B1049’s sacrifice, that GTO will be “supersynchronous,” meaning that the high end of the elliptical orbit – with the other end still around 300 kilometers – will likely end up around 60,000 kilometers (~37,500 mi) above Earth’s surface. A geosynchronous orbit is a circular orbit at an altitude of around 35,800 kilometers (~22,250 mi), where orbital velocity matches the speed of Earth’s rotation and allows a satellite to hover over a region of choice.

A supersynchronous GTO allows a satellite to circularize its orbit more efficiently, saving a significant amount of propellant. The relatively low cost of geostationary stationkeeping means that saving even a modest amount of propellant can add years of life to a satellite, increasing the maximum amount of revenue it can generate in its lifetime. Additionally, the higher orbit should allow Eutelsat 10B to begin serving customers a few weeks earlier. While Eutelsat likely had to pay an unknown fee (perhaps tens of millions of dollars) for SpaceX to expend B1049, the benefits must outweigh that added cost.

Culling the herd

The unprecedented culling of SpaceX’s rocket ‘herd’ began on November 1st when the company intentionally expended one of three Falcon Heavy boosters (B1066) during the massive rocket’s first launch since June 2019. Four launches into its life, SpaceX has never successfully recovered a Falcon Heavy center core – a trend that appears unlikely to end anytime soon thanks to a string of 2023 launches that will all reportedly demand extra performance from the rocket.

Next, on November 12th, SpaceX launched Intelsat’s Galaxy 31 and Galaxy 32 satellites to a similar supersynchronous transfer orbit, expending Falcon 9 booster B1051 in the process. Following B1049’s demise on November 22nd, SpaceX has expended a record three Falcon boosters in one month. The last time SpaceX intentionally expended two Falcon boosters in the same month was June 2018.

SpaceX’s rocket fleet now has 14 flight-proven Falcon boosters with an average of 8.7 launches per core. At least two new reusable boosters (B1076 and B1078) will enter the fleet within the next several months.

SpaceX calls off Starship 10 flight attempt once again

SpaceX is calling off a potential launch of Starship this evening, marking the second consecutive night the tenth test flight of the massive rocket will be delayed.

SpaceX is calling off a potential launch of Starship this evening, marking the second consecutive night the tenth test flight of the massive rocket will be delayed.

Originally planning to launch on Sunday at 6:30 p.m. local time in Starbase, Texas, SpaceX was forced to delay the tenth launch of Starship due to a hardware issue.

“Ground side liquid oxygen leak needs to be fixed. Aiming for another launch attempt tomorrow,” CEO Elon Musk posted on the social media platform X.

The launch was then pushed to Monday night, and the launch window was set to start at the same time as Sunday. However, SpaceX would push it back to 6:44 p.m. due to some weather issues.

Eventually, Starship seemed like it was trending toward a launch, but weather continued to persist in the area, with thunder, rain, and lightning all threatening in the area.

At around 7:03 p.m., SpaceX decided to stand down once again, confirming weather was the culprit of yet another delay:

SpaceX will likely try again on Tuesday night, but the company has not yet confirmed if it will open another launch window.

WATCH: SpaceX Starship Flight 10 launch

SpaceX is set to launch its tenth test flight of the Starship program, with a launch window that will open at 6:44 p.m. local time, or 7:44 p.m. on the East Coast.

Starship’s tenth test flight was originally scheduled for launch yesterday with a one-hour window that opened at 7:30 p.m. ET, but it was called off 17 minutes before that window even had a chance to open.

SpaceX moved the flight to tonight. It was also originally scheduled to have a launch window at the same time as Sunday, but it was pushed back 14 minutes to around 6:30 p.m. ET. There are storms in the area, as well as clouds over Starbase, so there is the off chance for another launch delay.

There are several big objectives for this launch, including the expansion of the operating envelope for the Super Heavy booster. SpaceX says there are “multiple landing burn tests planned.”

The booster will also be performing a few in-flight experiments to help with data collection. Specifically, real-world performance data on future flight profiles and off-nominal scenarios will be on the list of things SpaceX will be looking for.

Starship itself will have a few in-flight objectives that include the deployment of eight Starlink simulators that are similar in size to the next-gen satellites for the internet service. SpaceX was set to test this with Starship’s seventh test flight, which occurred in January 2025. However, the task was abandoned as the vehicle was destroyed before deployment could occur.

Liftoff conditions are currently looking favorable, and SpaceX will be eager to improve upon its Starship launch program as CEO Elon Musk has big plans for it in the coming years.

Tesla looks to expand Robotaxi geofence once again with testing in new area

It looks as if Tesla is preparing for its next expansion of the geofence, potentially moving toward a much larger service area that could eclipse 150 square miles.

Tesla looks to be preparing for the potential expansion of the Robotaxi geofence once again, as the company was spotted testing the suite in an area well outside of the Austin service area.

After it first launched the Robotaxi platform on June 22, Tesla has managed to expand its geofence twice, essentially doubling the travel area both times.

The most recent expansion took the size of the geofence from 42 square miles to about 80 square miles, bringing new neighborhoods and regions of the city into the realm of where the driverless vehicles could take passengers.

However, it looks as if Tesla is preparing for its next expansion of the geofence, potentially moving toward a much larger service area that could eclipse 150 square miles.

Over the weekend, one fan noticed a Robotaxi validation vehicle testing in Bee Cave, Texas, which is roughly 25 minutes from the edge of the current geofence:

Tesla has been testing vehicles in the western suburbs of Austin for some time, and it seems the company is laying some groundwork to push its geofence expansion into Plaid Mode as competition with Waymo continues to be at the forefront of the conversation.

Waymo has been expanding with Tesla for some time, as the pace of expansion for the two companies has been relatively accelerated for the past couple of months.

Tesla’s expansions of the geofence sent a clear message to competitors and doubters, but it is still aiming to keep things safe and not push the envelope too quickly.

The geofence expansion is impressive, but Tesla is also focusing on expanding its vehicle fleet in both Austin and the Bay Area, where it launched a ride-hailing service in July.

Still, safety is the priority at the current time.

“We are being very cautious. We do not want to take any chances, so we are going to go cautiously. But the service areas and the number of vehicles in operation will increase at a hyper-exponential rate,” CEO Elon Musk said during the Q2 Earnings Call.
