SpaceX test-fires Falcon 9 Block 5 booster for upgraded rocket’s fifth launch
After a couple of weeks of mysterious delays, SpaceX is once again back in the saddle for its next orbital mission and has successfully completed Falcon 9’s routine prelaunch wet dress rehearsal and static fire. This rocket will launch Telstar 19V’s (launched in July) sister communications satellite Telstar 18V to a high-energy transfer orbit at 11:28 PM EDT, September 8 (03:28 UTC, September 9).
SpaceX’s static fire testing – conducted once in Texas with just the first stage and once at the launch site with the upper stage attached – is very nearly identical to a real launch, save for the fact that the rocket is not allowed to actually lift off from the pad, and only ignites its main engines for a handful of seconds.

Almost entirely unique to SpaceX in the launch industry, Falcon 9 and Falcon Heavy are perhaps the only operational (orbital-class) rockets in the world to still conduct routine test fires of integrated segments, including both boosters, upper stages, and even Dragon spacecraft thrusters (both Crew and Cargo variants). Other launch providers like ULA, Arianespace, and Roscosmos will typically test engines individually, but that testing is often not even routine – spot checks more than anything systematic.
In fact, SpaceX’s system of hardware testing as extraordinarily extensive. Aside from test firing integrated boosters and upper stages, SpaceX doubles down on that testing both at the launch site and in Texas. Prior to integrated testing, essentially all rocket engines (sea-level Merlin 1Ds, vacuum Merlin 1Ds, SuperDraco thrusters, Draco thrusters, and Falcon’s cold gas maneuvering thrusters) are hot-fire (or cold-fire, in the case of the cold gas thrusters) tested in Texas after completing assembly in Hawthorne.

After that, the individual rocket engines and thrusters are shipped back to Hawthorne, integrated into their Dragon, Falcon upper stage, or Falcon booster parent rocket, and then shipped back to Texas once more for integrated test-fires, shipped to their launch site, and test-fired yet again (in the case of Falcon 9 and Heavy, not Dragon). This extraordinarily systematic testing apparatus is without a doubt unique to SpaceX, with the only closest comparison being found in small launch startup Rocket Lab, which is also extensively vertically integrated, including in-house tests of all engines prior to shipment.
Much like modern aircraft (particularly airliners) routinely test all critical systems prior to takeoff, particularly a full-thrust engine check with brakes applied, SpaceX and Rocket Lab are explicitly attempting to replicate in spaceflight the sort of practices that have helped to make air travel perhaps the safest and most reliable method of transportation ever created by humans.

Starlink makes a difference in Philippine province ravaged by typhoon
The Severe Tropical Storm battered the province, leaving communications networks in the area in shambles.

The Philippines’ Department of Information and Communications Technology (DICT) is using Starlink to provide connectivity in the municipality of Masbate, which was affected by Severe Tropical Storm Opong (international name Bualoi).
The Severe Tropical Storm battered the province, leaving communications networks in the area in shambles.
Starlink units enhance connectivity
DICT Secretary Henry Aguda visited the province to assess internet and communications infrastructure and deliver 10 additional Starlink satellite units, according to the Philippine News Agency. The is move aimed at strengthening emergency response and restore digital access to the area.
Aguda met with Masbate Governor Richard Kho during his visit and joined telecommunications representatives in inspecting provincial offices, free charging stations, and Wi-Fi connectivity sites for residents.
According to DICT officer-in-charge Rachel Ann Grabador, three Starlink units, 10 routers, and a 2kW solar-powered station have already been deployed in the province following the typhoon. The units have been installed at key facilities such as Masbate Airport’s communications tower and the Masbate Provincial Hospital’s administrative office.
Game-changing technology
Thanks to its global coverage and its capability to provide high-speed internet connectivity even in remote areas, Starlink has become the best communications solution that can be deployed in the aftermath of natural disasters. Its low-cost kits, which are capable of of providing fast internet speeds, are also portable, making them easy to deploy in areas that are damaged by natural disasters.
As noted in a Space.com report, there are currently 8,475 Starlink satellites in orbit, of which 8,460 are working, as of September 25, 2025. Initially, SpaceX had filed documents with International regulators to place about 4,000 Starlink satellites in Low Earth Orbit. Over time, however, the number of planned Starlink satellites has grown, with SpaceX aiming to launch as many as 42,000 Starlink satellites to fully connect the globe.

SpaceX shares targets and tentative launch date for Starship Flight 11
As with all SpaceX tests, the estimated timeline for Starship Flight 11 remains subject to change based on conditions and readiness.

SpaceX is targeting Monday, October 13, for the eleventh test flight of its Starship launch system. The launch window is expected to open at 6:15 p.m. CT.
Similar to past Starship missions, a live webcast will begin about 30 minutes before launch on SpaceX’s website, X account, and X TV app. As with all SpaceX tests, the estimated timeline for Starship Flight 11 remains subject to change based on conditions and readiness.
Super Heavy booster landing test
The upcoming mission will build on the data gathered from Starship’s tenth test flight, focusing on booster performance and upper-stage capabilities. The Super Heavy booster, previously flown on Flight 8, will launch with 24 flight-proven Raptor engines, according to SpaceX in a blog post on its official website. Its primary objective is to validate a new landing burn engine configuration designed for the next generation of Super Heavy.
Instead of returning to Starbase, the Super Heavy booster will follow a trajectory toward the Gulf of America. During descent, it will ignite 13 engines before transitioning to a five-engine divert phase and then completing the landing burn with three central engines, entering a full hover while still above the ocean surface, followed by shutdown and dropping into the Gulf of America.
Starship upper-stage experiments
The Starship upper stage for Flight 11 will carry out a series of in-space demonstrations, including the deployment of eight Starlink simulators that are comparable in size to next-generation Starlink satellites. These payloads will reenter and burn up during descent. A planned Raptor engine relight in orbit will also provide valuable test data.
To evaluate the upper stage’s resilience during reentry, SpaceX engineers have intentionally removed heat shield tiles from select areas to stress-test Starship’s thermal protection system. The vehicle will attempt new maneuvers during descent, including a banking profile and subsonic guidance algorithms intended to simulate future return-to-launch-site missions. The upper stage will ultimately target a splashdown in the Indian Ocean.
SpaceX has already posted a link to the livestream for Starship Flight 11:

Astra CEO shades SpaceX over employee workload and Starbase
Elon Musk once stated that no one ever changed the world working just 40 hours a week.

Elon Musk once stated that no one ever changed the world working just 40 hours a week. This was something that is openly known among his companies. They have the potential to change the world, but they require a lot of hours.
SpaceX’s working environment was recently criticized by Chris Kemp, the chief executive officer of Astra. During some remarks at the Berkeley Space Symposium 2025 earlier this month, Kemp shared some sharp remarks about the Elon Musk-led private space enterprise.
SpaceX working conditions and Starbase
As noted in a report from Ars Technica, Kemp discussed a variety of topics during his talk. These included Astra’s successes and failures, as well as his thoughts on other players in the spaceflight industry. To be fair to Kemp, he practically shaded every major rival, calling Firefly’s engine “garbage,” dubbing Blue Origin as slow, and stating that Rocket Lab’s Electron rocket is “too small.”
SpaceX also received some colorful words from the Astra CEO. According to Kemp, SpaceX is leading the way in the spaceflight industry and Elon Musk is admirable in the way that he is willing to fail in order to move quickly. He did, however, highlight that Astra offers a significantly better working environment than SpaceX.
“It’s more fun than SpaceX, because we’re not on the border of Mexico where they’ll chop your head off if you accidentally take a left turn. And you don’t have to live in a trailer. And we don’t make you work six and a half days a week, 12 hours a day. It’s appreciated if you do, but not required,” Kemp said.
Elon Musk’s demands
It is known that Elon Musk demands quite a lot from his employees. However, it is also known that Musk-led companies move very fast and, in more ways than one, they have accomplished world-changing feats. Tesla, for example, has practically ushered in the era of the modern electric vehicle, and SpaceX has made space attainable through its reusable rockets. With this in mind, employees at Musk’s companies, and this of course includes SpaceX, are likely proud of their long work hours.
No one could probably go to Mars in this lifetime with a team that really works just 40 hours a week, after all.
