SpaceX has successfully ignited a Block 5 variant of its Falcon Heavy rocket for the first time ever, also marking the second-ever integrated static fire of the heavy-lift launch vehicle. According to SpaceX, the company will aim for an extraordinary four-day turnaround from static fire to launch, targeting liftoff as early as 6:36 pm EDT (22:36), April 9th.

Captured in a spectacular 4K video from a few miles away, it appears that the giant rocket managed to ignite all 27 Merlin 1D engines for no more than 3-4 seconds, an average length for Falcon 9 but quite a bit shorter than the 7-10 seconds Falcon Heavy fired for during its Flight 1 preparations.

During the Block 5 rocket’s first-ever integrated ignition test, all 27 Merlin 1D engines were (nominally) ignited in sequence, albeit just a handful of milliseconds apart from each other. During Falcon Heavy’s inaugural static fire and launch, CEO Elon Musk indicated that performance was capped at ~92% – 4.7 million pounds (~2115 metric tons) of thrust – for unspecified reasons. Assuming SpaceX has decided to uncap Falcon Heavy’s performance this time around, the rocket could have produced upwards of 5.6 million pounds (2550 metric tons) of thrust and will – again, according to Musk – have “way more performance than last year’s vehicle.” On top of the 8% increase from uncapping the rocket’s performance, Falcon 9 Block 5 introduced an additional 10% thrust increase for Merlin 1D engines, ultimately raising Falcon Heavy’s max thrust by a spectacular 20% in just one year.

With three times as many boosters as a single core Falcon 9 rocket, a Falcon Heavy static fire fundamentally produces as much as 100% more (2X as much) data as Falcon 9 during, requiring a fair bit more time to have engineers comb through it to verify vehicle health. The ultimate goal is for the vast majority of this work to be done by the rocket itself, which is actually what ends up shining through during what is known as the ‘quick-look review’ that shortly follows static fires, but Falcon Heavy is likely too new of a rocket for that just yet.

To temper expectations for this highly-anticipated launch, SpaceX took more than eight days to take Falcon Heavy Flight 1 from a planned static fire attempt to actual ignition, with an additional 13 days separating the successful static fire and the first official launch window. The consequences of sidestepping caution with Falcon Heavy could reach as high as the near-complete destruction of SpaceX’s Launch Complex 39A pad facilities, an absolutely mission-critical foundation for the first attempted crew launch of Crew Dragon and future astronaut launches to the International Space Station (ISS). As such, any unnecessary risk itself risks raising the ire of NASA and the US government in general, as it would also fundamentally be a conscious decision to risk the stability of US access to the Space Station for the sake of shaving a few days or weeks off of a commercial launch schedule.

SpaceX typically provides an update via Twitter 15-60 minutes after a Falcon preflight static fire test to announce whether the data generally looks good or if additional time is needed to analyze the rocket’s performance. According to a since-deleted USAF 45th Space Wing tweet, a healthy-looking static fire from Falcon Heavy Flight 2 would pave the way for a launch attempt no earlier than 6:36 pm EDT (22:36 UTC), April 9th.

This article will be updated with any additional information about Falcon Heavy’s health and launch date targets as soon as it becomes available.

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.
