SpaceX to launch Falcon Heavy rocket 3 times in 6 months after latest payload delay

For at least the second time in 2021, unspecified issues with a US military payload have delayed SpaceX’s next Falcon Heavy launch, this time pushing the mission into next year.

Known as USSF-44 (formerly AFSPC-44), the US Air Force (now Space Force) contracted a SpaceX Falcon Heavy rocket in February 2019 to launch the classified payload for roughly $150M in fiscal year 2021 (no earlier than Q4 2020). Gradually, USSF-44 slipped without explanation to Q2 2021, at which point SpaceX had fully qualified and delivered all three new Falcon Heavy boosters and an expendable upper stage for the mission. After two more slips to July and October 2021, a US military official finally offered the first hint of an explanation for what now amounted to a full year of delays, explaining that USSF-44 had been pushed into Q4 “to accommodate payload readiness.”

Translated from US military doublespeak and euphemism, the manufacturer (likely Lockheed Martin, Northrop Grumman, or Boeing) building USSF-44’s classified payload(s) ran into or create issues that caused at least 3-6 months of delays. Now, per official comments obtained from a Space Force spokesperson by Spaceflight Now, USSF-44 has again been delayed several months “to accommodate payload readiness,” pushing Falcon Heavy’s fourth launch ever from October 2021 to no earlier than (NET) Q1 2022.

USSF-44’s latest delay means that SpaceX is now likely to go a full 30 months between Falcon Heavy flights after completing the rocket’s third and most recent launch in June 2019. The slip to “early 2022” also leaves the company with an extremely ambitious launch manifest in the first half of 2022. Barring one or several significant delays, which now seems like the most plausible outcome, SpaceX has four major Falcon Heavy missions – USSF-44, USSF-52, ViaSat-3, and NASA’s Psyche probe – scheduled to launch set to launch by August, with three of the four scheduled in H1 2022. A fifth mission – USSF-67 – is scheduled to launch in Q4 2022 and likely on another Falcon Heavy rocket, though the US military has yet to specify the Falcon variant.

Further, requiring the use of the same Kennedy Space Center (KSC) LC-39A pad, SpaceX also has at least six Crew and Cargo Dragon launches scheduled in February (Ax-1), April (Crew-4), May (CRS-25), Q3 (Ax-2), September (CRS-26), and October 2022 (Crew-5). In other words, in Dragon and Falcon Heavy missions alone, SpaceX already has 10-11 launches scheduled in 2022 – all of which require the use of Pad 39A. If SpaceX manages to pull that off on top of a myriad of other commercial and Starlink launches scheduled next year, it will be a feat to remember.

Barring additional delays, USSF-44 will be SpaceX’s first direct launch to geostationary orbit (GEO), requiring the Falcon upper stage to survive a multi-hour coast through and inside two radiation belts before reigniting for a circularization burn some 35,800 km (22,300 mi) above Earth’s surface. However, a rideshare payload transferred to SpaceX’s ViaSat-3 communications satellite launch recently revealed that SpaceX also intends to send those payloads directly to GEO in Q2 2022, meaning that another few months could force the company to leapfrog USSF-44.

For now, fans of the most powerful operational rocket in the world will have to wait at least another three months for its next launch.

Why Tesla’s Q3 could be one of its biggest quarters in history

Tesla could stand to benefit from the removal of the $7,500 EV tax credit at the end of Q3.

Tesla has gotten off to a slow start in 2025, as the first half of the year has not been one to remember from a delivery perspective.

However, Q3 could end up being one of the best the company has had in history, with the United States potentially being a major contributor to what might reverse a slow start to the year.

Earlier today, the United States’ House of Representatives officially passed President Trump’s “Big Beautiful Bill,” after it made its way through the Senate earlier this week. The bill will head to President Trump, as he looks to sign it before his July 4 deadline.

The Bill will effectively bring closure to the $7,500 EV tax credit, which will end on September 30, 2025. This means, over the next three months in the United States, those who are looking to buy an EV will have their last chance to take advantage of the credit. EVs will then be, for most people, $7,500 more expensive, in essence.

The tax credit is available to any single filer who makes under $150,000 per year, $225,000 a year to a head of household, and $300,000 to couples filing jointly.

Ending the tax credit was expected with the Trump administration, as his policies have leaned significantly toward reliance on fossil fuels, ending what he calls an “EV mandate.” He has used this phrase several times in disagreements with Tesla CEO Elon Musk.

Nevertheless, those who have been on the fence about buying a Tesla, or any EV, for that matter, will have some decisions to make in the next three months. While all companies will stand to benefit from this time crunch, Tesla could be the true winner because of its sheer volume.

If things are done correctly, meaning if Tesla can also offer incentives like 0% APR, special pricing on leasing or financing, or other advantages (like free Red, White, and Blue for a short period of time in celebration of Independence Day), it could see some real volume in sales this quarter.

Tesla is just a shade under 721,000 deliveries for the year, so it’s on pace for roughly 1.4 million for 2025. This would be a decrease from the 1.8 million cars it delivered in each of the last two years. Traditionally, the second half of the year has produced Tesla’s strongest quarters. Its top three quarters in terms of deliveries are Q4 2024 with 495,570 vehicles, Q4 2023 with 484,507 vehicles, and Q3 2024 with 462,890 vehicles.

Tesla Full Self-Driving testing continues European expansion: here’s where

Tesla has launched Full Self-Driving testing in a fifth European country ahead of its launch.

Tesla Full Self-Driving is being tested in several countries across Europe as the company prepares to launch its driver assistance suite on the continent.

The company is still working through the regulatory hurdles with the European Union. They are plentiful and difficult to navigate, but Tesla is still making progress as its testing of FSD continues to expand.

Today, it officially began testing in a new country, as more regions open their doors to Tesla. Many owners and potential customers in Europe are awaiting its launch.

On Thursday, Tesla officially confirmed that Full Self-Driving testing is underway in Spain, as the company shared an extensive video of a trip through the streets of Madrid:

The launch of Full Self-Driving testing in Spain marks the fifth country in which Tesla has started assessing the suite’s performance in the European market.

Across the past several months, Tesla has been expanding the scope of countries where Full Self-Driving is being tested. It has already made it to Italy, France, the Netherlands, and Germany previously.

Tesla has already filed applications to have Full Self-Driving (Supervised) launched across the European Union, but CEO Elon Musk has indicated that this particular step has been the delay in the official launch of the suite thus far.

In mid-June, Musk revealed the frustrations Tesla has felt during its efforts to launch its Full Self-Driving (Supervised) suite in Europe, stating that the holdup can be attributed to authorities in various countries, as well as the EU as a whole:

Tesla Full Self-Driving’s European launch frustrations revealed by Elon Musk

“Waiting for Dutch authorities and then the EU to approve. Very frustrating and hurts the safety of people in Europe, as driving with advanced Autopilot on results in four times fewer injuries! Please ask your governing authorities to accelerate making Tesla safer in Europe.”

Tesla said last year that it planned to launch Full Self-Driving in Europe in 2025.

xAI’s Memphis data center receives air permit despite community criticism

xAI welcomed the development in a post on its official xAI Memphis account on X.

Elon Musk’s artificial intelligence startup xAI has secured an air permit from Memphis health officials for its data center project, despite critics’ opposition and pending legal action. The Shelby County Health Department approved the permit this week, allowing xAI to operate 15 mobile gas turbines at its facility.

Air permit granted

The air permit comes after months of protests from Memphis residents and environmental justice advocates, who alleged that xAI violated the Clean Air Act by operating gas turbines without prior approval, as per a report from WIRED. 

The Southern Environmental Law Center (SELC) and the NAACP has claimed that xAI installed dozens of gas turbines at its new data campus without acquiring the mandatory Prevention of Significant Deterioration (PSD) permit required for large-scale emission sources.

Local officials previously stated the turbines were considered “temporary” and thus not subject to stricter permitting. xAI applied for an air permit in January 2025, and in June, Memphis Mayor Paul Young acknowledged that the company was operating 21 turbines. SELC, however, has claimed that aerial footage shows the number may be as high as 35.

Critics are not giving up

Civil rights groups have stated that they intend to move forward with legal action. “xAI’s decision to install and operate dozens of polluting gas turbines without any permits or public oversight is a clear violation of the Clean Air Act,” said Patrick Anderson, senior attorney at SELC.

“Over the last year, these turbines have pumped out pollution that threatens the health of Memphis families. This notice paves the way for a lawsuit that can hold xAI accountable for its unlawful refusal to get permits for its gas turbines,” he added.

Sharon Wilson, a certified optical gas imaging thermographer, also described the emissions cloud in Memphis as notable. “I expected to see the typical power plant type of pollution that I see. What I saw was way worse than what I expected,” she said.
