SpaceX’s Falcon 9 Block 5 rocket gets its first public launch date on April 24
After an unusually extended period of testing in McGregor, Texas, SpaceX’s next-generation Falcon 9 Block 5 booster (B1046) appears to be scheduled for an inaugural flight as early as April 24, a three-week recalibration from the original April 5 launch date.
New hardware, new bugs
A fairly significant leap from the current Block 3 and 4 iterations of Falcon 9, it should come as no surprise that the first Block 5 booster has taken a bit longer than anticipated to pass through its first integrated static fire testing and inaugural launch preparations. Put simply, new hardware takes time and safety and reliability take near-complete precedence over expediency.

Arguably, the better part of half of all of SpaceX’s planned 2018 launches will depend heavily on the Block 5 upgrade of Falcon 9 (and Heavy), especially if the company still intends to complete 20-25 launches between now and the end of the year. Per a relatively new strategy of intentional expending recoverable, flight-proven Falcon 9 boosters after their second launches, SpaceX is on track to effectively deplete their stock of non-Block 5 hardware well before the second half of 2018. As such, approaching Block 5’s introduction with extreme caution (as with most things in rocketry) is undoubtedly in SpaceX’s best interest. The gradual march to B1046’s first flight will thus continue forth to NET April 24 – subject to change, of course.
CONFIRMED by @Thales_Alenia_S, Bangabandhu-1 is manifested to launch on the first 'Block-5' Falcon 9 rocket, NET April 24.
From Thales, "This has resulted in some extra delay. However, Bangabandhu-1 will fly on the most advanced and reliable vehicle ever built by #SpaceX"

Thales-Alenia’s confirmation lends credence to the argument that the relatively lengthy period B1046 spent in Texas was simply SpaceX giving a complex and new technological system its due diligence – better to test cautiously and fix bugs than to rush complex procedures and damage the rocket, an eventuality likely to push any tentative launch date back to a much greater extent.

Launches abound
With Bangabandhu-1 now officially scheduled NET April 24, the SpaceX focal point can return to a flurry of upcoming launches – Iridium-5 (NET Mar 30), CRS-14 (NET April 2), and TESS (NET April 16). Teslarati photographers Pauline Acalin (West Coast) and Tom Cross (East Coast) will be on the ground for all upcoming launches to capture some of the final swan songs of SpaceX’s rapidly diminishing stock of flight-proven Falcon 9s.

SpaceX and Elon Musk explain potential reasons for Starship loss

SpaceX and its CEO Elon Musk are starting to shed some light on the potential reasoning for the loss of Starship yesterday, which was lost after a successful launch and catch of the lower-stage booster.
Starship was lost during its ascension, and debris rained down over the Caribbean less than an hour after SpaceX lost all communication with the spacecraft.
A few hours after the launch was over, SpaceX started to shed some light after looking at preliminary data that the rocket left behind.
The company said that a fire developed in the aft section of Starship:
“Following stage separation, the Starship upper stage successfully lit all six Raptor engines and performed its ascent burn to space. Prior to the burn’s completion, telemetry was lost with the vehicle after approximately eight and a half minutes of flight. Initial data indicates a fire developed in the aft section of the ship, leading to a rapid unscheduled disassembly with debris falling into the Atlantic Ocean within the predefined hazard areas.”
Additionally, Musk said that there was some sort of oxygen or fuel leak in the cavity above the ship engine firewall.
The leak was evidently large enough to build more pressure than the vent was able to handle:
🚨Elon Musk has also said an oxygen or fuel leak in the cavity above the ship engine firewall could be the cause of the anomaly. https://t.co/BgLkdA9Kk1

Some also seemed to recognize evidence of fires throughout the flight of Starship, which is obviously an anomaly:
Unconfirmed but what looks to be fire at the hinge of Starship’s flap. A potential RUD? We await as we get any confirmation from SpaceX.

— Mihir Tripathy (@mihirneal) January 16, 2025
There will be more information regarding the loss of Starship in the coming days and weeks, but Musk already believes that a bit of fire suppression and more volume in the cavity above the ship engine firewall could fix the issue.
“Nothing so far suggests pushing next launch past next month,” he said, so Flight 8 could happen sometime in February.

SpaceX completes second catch of lower stage, but loses Starship

SpaceX completed its seventh launch of Starship on Thursday, accomplishing a clean liftoff and catch of the first-stage booster. However, the upper stage was lost after its ascent.
The launch took place just a few minutes after 5 p.m. on the East Coast, as the first attempts at getting Starship in the air for the seventh time were delayed by weather both last week and this week.
Conditions were favorable on Thursday as SpaceX looked to follow up a successful campaign by Blue Origin, Jeff Bezos’s company, earlier today.
SpaceX went into the seventh Starship launch with plans for a catch attempt of the first-stage booster, something it attempted and completed during the fifth test launch last year. It decided to skip a catch attempt with the sixth test flight as conditions were not aligned.
For now, SpaceX is extremely selective as to when it attempts catches.
However, it was successful during this attempt, its second completed catch:

— TESLARATI (@Teslarati) January 16, 2025
This flight differed from previous launches as SpaceX rolled out several improvements to the rocket and the processes as it featured plans to do a Starlink deployment simulation and had various adjustments to flap placement and avionics.
These plans were disrupted by the fact that SpaceX lost all communications with Starship about ten minutes into the flight, which the aerospace company confirmed was a result of losing the spacecraft sometime during its ascent.
🚀🚨 Telemetry on Starship has been lost. All comms with the ship have been lost, and SpaceX’s livestream says this is an “anomaly.”
“We are assuming the ship has been lost.” pic.twitter.com/fyyCNuXVRg
— TESLARATI (@Teslarati) January 16, 2025
Although the catch was successful, the loss of the actual rocket seemed to be a huge damper on the entire event. SpaceX confirmed several minutes after the loss of communications that the rocket was destroyed and was lost.
It was its first failure since the second Starship launch in November 2023. SpaceX had no answers for why the rocket was destroyed and lost.
We will keep you updated in the coming days.

SpaceX confirms next Starship launch target – Here’s when it will take off

SpaceX has confirmed a new target date for the seventh Starship test launch after weather in Texas delayed the first scheduled date for “three or four days.”
The company is now targeting the launch for Monday, January 13, at 4 p.m. CST or 5 p.m. EST. The launch date is not set in stone as any variety of delays could impact this, but SpaceX hopes to finally take off after a delay that pushed it back from January 10.
🚨 STARSHIP LAUNCH DATE: @SpaceX says Starship’s 7th test flight is now targeted for Monday, January 13 at 4pm CST

What’s new with this Starship launch
With this being the seventh test launch of Starship, there are several things that the company will change and hope to accomplish. All of these launches are done in preparation for eventually taking flight to Mars, something that will happen next year, according to CEO Elon Musk.
First, SpaceX is rolling out a next-generation ship with “significant upgrades.” Forward flaps have been made smaller and are repositioned away from the heat shield, which will “reduce their exposure to reentry heating.”
There is also a 25 percent increase in propellant volume, a new fuel feedline system for the Raptor vacuum engines, and a better-than-ever propulsion avionics module that will control the valves and reading sensors.
Avionics, as a whole, underwent a redesign and now have more capability and redundancy for missions as they become more complex.
Starlink test
SpaceX is also planning to deploy 10 Starlink simulators that are similar in size and weight to the next-generation Starlink satellites:
“While in space, Starship will deploy 10 Starlink simulators, similar in size and weight to next-generation Starlink satellites as the first exercise of a satellite deploy mission. The Starlink simulators will be on the same suborbital trajectory as Starship, with splashdown targeted in the Indian Ocean. A relight of a single Raptor engine while in space is also planned.”
Ship return and catch
There will be several experiments that have to do with returning Starship and various catch scenarios and sequences. One of which will see “a significant number of tiles be removed to stress-test vulnerable areas across the vehicle.”
The ship’s reentry profile was also intentionally designed to test the structural limits of the flaps while at the point of maximum dynamic pressure during reentry.
Currently, SpaceX did not detail whether it would attempt another catch during this test launch. These are usually game-time decisions.
