SpaceX is T-18 hours to its second Falcon Heavy launch in barely 70 days, set to lift off with the Department of Defense’s Space Test Program-2 (STP-2) rideshare mission no earlier than (NET) 11:30 pm EDT (03:30 UTC), June 24th.

According to SpaceX CEO Elon Musk, STP-2 is without a doubt the company’s “most difficult launch ever”, owing to a multitude of high-stakes performance requirements, US military and NASA oversight, several technical milestones, challenging booster and fairing recoveries, and much, much more. Should SpaceX succeed on all fronts, the company will have taken a massive leap towards being able to offer competitive launch services that can fulfill all of the US government’s many different spaceflight needs.

Challenges all the way down

Likely the single most challenging aspect of STP-2 is the performance the mission’s Falcon 9 upper stage will have to deliver. SpaceX describes the challenge below:

“[The STP-2 mission] will deliver 24 satellites to space on the DoD’s first-ever SpaceX Falcon Heavy launch. [It] will be among the most challenging launches in SpaceX history, with four separate upper-stage engine burns, three separate deployment orbits, a final propulsive passivation maneuver, and a total mission duration of over six hours.”

According to older USAF documents (STP-2’s original launch target was mid-2015), those numbers could actually rise as high as five separate upper-stage Merlin Vacuum burns and a mission duration of more than 7.5 hours. Given the last-second decision to move Falcon Heavy’s center core recovery from ~40 km offshore to more than 1240 km offshore, it’s fairly likely that five burns and 7.5 hours will be closer to the reality of STP-2. In short, the center core will move from a gentle recovery to what will probably be SpaceX’s hottest and hardest booster recovery ever to transfer as much margin as possible to STP-2’s upper stage.

With regard to that extra spicy reentry, Falcon Heavy center core B1057 – the second Block 5 center core built by SpaceX – is now expected to attempt a landing aboard drone ship Of Course I Still Love You (OCISLY) more than 1240 km (770 mi) off the coast of Florida, potentially smashing the current record of ~970 km (600 mi).

At the same time, fairing recovery vessel GO Ms. Tree (formerly Mr. Steven; renamed due to change in ownership) is steaming hard, heading anywhere from 1400-1600 km into the Atlantic Ocean. Falcon Heavy STP-2 will be the vessel’s first attempted fairing catch since December 3rd, 2018, nearly seven months ago. It will likely crush the previous record for most distant fairing recovery attempt by 50% or more. Whether or not the vessel succeeds and catches its first Falcon fairing(s) ever, it’s exciting to see Ms. Tree (Mr. Steven) out and about for a fairing recovery after months of inactivity.

As always, SpaceX will host an official Falcon Heavy STP-2 livestream, beginning around T-15 minutes and likely lasting at least 1-2 hours as the rocket’s upper stage prepares for a ~7.5-hour orbital marathon.

SpaceX announces new Starship 13 test flight target date

SpaceX has announced a new target date for the thirteenth test flight of Starship: Monday, July 20, with the launch window opening at 6:45 p.m ET/5:45 p.m. CT.

This is the first rescheduling attempt of Starship’s 13th test flight. It was set to launch last night, but SpaceX scrubbed the launch attempt.

CEO Elon Musk revealed that some of the engines on Starship did not start, which automatically triggers a launch abort. Two of the Raptor engines will be removed and replaced.

SpaceX officially announced the new launch window this morning.

Starship’s 13th test launch comes with a few new objectives, but SpaceX does not plan to attempt a catch of the booster, which it has done several times in the past.

For Starship’s Upper Stage, there are some adjustments to ensure engine reusability that will be assessed during the ascent, and 20 operational Starlink V3 satellites are also set to make their way into space. SpaceX also plans to attempt an in-space relight of a single Raptor engine, which is a critical demonstration for future orbital deorbit, refueling, and deep space maneuvers.

Ultimately, it will splash down in the Indian Ocean.

The continuous tests help SpaceX advance the Starship program toward eventual full reusability, operational Starlink V3 deployment, and future missions, which include NASA’s Artemis program.

SpaceX Starship Flight 13 aborted at Zero and Musk just told us what broke

Four Raptor engines failed to ignite at T-zero, forcing SpaceX to scrub Starship Flight 13 Thursday.

SpaceX scrubbed the Starship Flight 13 launch attempt Thursday evening at the last possible moment, after four of the Super Heavy booster’s 33 Raptor 3 engines failed to ignite during the startup sequence. The 90-minute window had opened at 6:45 p.m. EDT from Starbase in Boca Chica, Texas, and the countdown had proceeded without issue all day, with more than 11.5 million pounds of liquid methane and liquid oxygen being fully loaded into the rocket before the automated abort triggered. SpaceX’s launch directors posted on X, “Standing down from today’s flight test attempt,” and shut down the livestream shortly after.

Musk confirmed the root cause within hours. “Some of the engines didn’t start, triggering an automatic launch abort,” he wrote on X. “To be confident of a good flight, 2 Raptors will be removed and replaced. Most probable launch timing is early next week.” SpaceX engineers began draining propellant tanks immediately and Booster 20 was rolled back to its hangar for inspection.

SpaceX comes with a slew of changes for Starship Flight 13

 

The timing adds a layer of significance that did not exist during any of the previous 12 Starship flights. This is the first time SpaceX has attempted to launch Starship since the company made its stock market debut in June, listing under ticker SPCX at $135 per share. Public investors are now watching every Starship outcome in real time, and a last-second abort carries more visibility than it would have six months ago.

Flight 13 was designed to be one of the most consequential tests in the program’s history. It was set to carry 20 Starlink V3 satellites, the first operational payload Starship has ever attempted to deploy. Six of those satellites carried external cameras to photograph Starship’s heat shield from the outside during flight, which would act as a self-inspection approach SpaceX has never attempted before. The mission also needed to complete a Raptor engine relight in space, a step SpaceX skipped on Flight 12 in May after losing an engine during ascent. That Flight 12 booster also flipped 90 degrees off course during its boostback burn when five engines failed to reignite.

SpaceX has not announced an official next launch date. Musk’s “early next week” window points to July 21 or 22 at the earliest, pending the engine swap and a return to the pad.

Elon Musk secretly acquires $1B energy company to power the AI future

Elon Musk flew under the radar with his recent purchase of a $1 billion energy company, according to Federal Trade Commission (FTC) documents.

Transaction number 202612350 listed Tesla and SpaceX frontman Elon Musk as the acquiring party and CF APR Super Holdings LLC as the seller, with New APR Energy, LLC as the acquired entity. The deal, which closed without public announcement, came to light on May 14.

Analysts inferred the deal’s scale from minority stakeholder disclosures, including one report of a 5 percent interest sold for approximately $50.4 million. Fortress Investment Group had purchased APR’s assets in late 2024, rebranded the operation as New APR Energy, and subsequently transferred ownership to Musk.

APR Energy specializes in rapidly deployable power infrastructure. The company maintains one of the world’s largest fleets of mobile gas and diesel turbines, with more than 1.1 gigawatts of generation capacity. Its modular units, which are often trailer-mounted, enable turnkey installations ranging from 20 MW to over 500 MW.

Elon Musk admits he was ‘clearly wrong’ about Anthropic

APR provides full engineering, procurement, construction, operation, and maintenance services for behind-the-meter power plants, serving everything from data centers, utilities, and industrial clients.

The firm has expanded aggressively to meet surging demand, recently adding turbines and deploying over 100 MW for a major AI hyperscaler. Its solutions bridge critical gaps where grid interconnections face delays of two to five years, according to Yahoo.

The acquisition means something more for Musk. As he continues to expand projects in artificial intelligence, especially xAI, his AI venture, there is a greater need to supply energy-intensive supercomputing clusters, including the Colossus project, with what they need: reliable and high-capacity power.

Ownership of APR provides immediate access to flexible generation assets that can be deployed adjacent to data centers, reducing dependence on a strained infrastructure. It also complements Tesla’s energy storage business, so Musk will be able to pull from his own entities to address the rapid scaling demands of AI training and compute.
