SpaceX, NASA call off Cargo Dragon launch after discovering fuel leak

Published

on

SpaceX and NASA have decided to call off an imminent Cargo Dragon 2 space station resupply mission after discovering a possible fuel leak while loading the spacecraft with propellant.

As a result, in an event that has become extremely rare for SpaceX, the launch has been indefinitely delayed after a recent series of slips from June 7th to the 9th, 10th, and 12th. Now, NASA says that it has fully stood down from any possible launch attempt this week, pushing CRS-25’s trip to the International Space Station (ISS) to June 13th at the absolute earliest.

“NASA and SpaceX are standing down from this week’s Falcon 9 launch of the CRS-25 cargo mission to the International Space Station. Officials from NASA and SpaceX met today to discuss an issue identified over the weekend and the best path forward.

During propellant loading of the Dragon spacecraft, elevated vapor readings of mono-methyl hydrazine (MMH) were measured in an isolated region of the Draco thruster propulsion system. The propellant and oxidizer have been offloaded from that region to support further inspections and testing. Once the exact source of the elevated readings is identified and cause is determined, the joint NASA and SpaceX teams will determine and announce a new target launch date.”


NASA – June 6th, 2022

The issue appears to have been discovered within the last few days, possibly explaining some of CRS-25’s small delays since May 19th. According to NASA, while loading Dragon with propellant, SpaceX detected “elevated vapor readings” of monomethylhydrazine (MMH) fuel in one “isolated region” related to the spacecraft’s propulsion system. After detecting the anomaly, SpaceX drained that particular section of fuel and oxidizer to allow for further inspections and testing to determine the “exact source” and its cause. Only once the source and cause have been determined will NASA and SpaceX announce a new launch date.

As is often the case with all kinds of rockets and spacecraft, there’s a good chance that the culprit of the unexpected detection of fuel vapors is a misbehaving valve. SpaceX will now need to figure out and fix exactly what went wrong before Cargo Dragon 2 C208 will be allowed to attempt its third orbital resupply mission since December 2020.

Perhaps even more importantly, given just how similar Cargo Dragon 2 is to SpaceX’s Crew Dragon spacecraft, the results of that investigation will have ramifications that reach far beyond a lower-risk uncrewed cargo delivery. As has been the case almost every day since November 2020, a Crew Dragon spacecraft is already docked with the ISS as part of an operational NASA astronaut transport mission. Crew-4’s Dragon is scheduled to return the four astronauts it recently carried to the station back to Earth as early as September 2022. A different Crew Dragon is scheduled to launch Crew-5 around the same time.

Given the similarity of all the reusable capsules in SpaceX’s Dragon fleet, there’s an omnipresent risk – however small – that any issue with one spacecraft could be present on all others. But on the opposite side of that sword, even the discovery of a more minor or isolated issue on any of SpaceX’s eight operational Dragon spacecraft – including uncrewed capsules like C208 – can help make the entire fleet safer and more reliable.

For now, CRS-25 has been effectively grounded. SpaceX’s next launch, carrying the Egyptian communications satellite Nilesat-301, is scheduled no earlier than (NET) June 8th.

Starlink wrapped up 2025 with impressive growth, adding more than 4.6 million new active customers and expanding service to 35 additional countries, territories, and markets. The company also completed deployment of its first-generation Direct to Cell constellation, launching over 650 satellites in just 18 months to enable cellular connectivity.

SpaceX highlighted Starlink’s impressive 2025 progress in an extensive report.

Key achievements from Starlink’s 2025 Progress

Starlink connected over 4.6 million new customers with high-speed internet while bringing service to 35 more regions worldwide in 2025. Starlink is now connecting 9.2 million people worldwide. The service achieved this just weeks after hitting its 8 million customer milestone.

Starlink is now available in 155 markets, including areas that are unreachable by traditional ISPs. As per SpaceX, Starlink has also provided over 21 million airline passengers and 20 million cruise passengers with reliable high-speed internet connectivity during their travels.

Starlink Direct to Cell

Starlink’s Direct to Cell constellation, more than 650 satellites strong, has already connected over 12 million people at least once, marking a breakthrough in global mobile coverage.
Starlink Direct to Cell is currently rolled out to 22 countries and 6 continents, with over 6 million monthly customers. Starlink Direct to Cell also has 27 MNO partners to date.

This year, SpaceX completed deployment of the first generation of the Starlink Direct to Cell constellation, with more than 650 satellites launched to low-Earth orbit in just 18 months. Starlink Direct to Cell has connected more than 12 million people, and counting, at least once, providing life-saving connectivity when people need it most,” SpaceX wrote.

Tesla Giga Nevada celebrates production of 6 millionth drive unit

To celebrate the milestone, the Giga Nevada team gathered for a celebratory group photo.

Tesla’s Giga Nevada has reached an impressive milestone, producing its 6 millionth drive unit as 2925 came to a close.

To celebrate the milestone, the Giga Nevada team gathered for a celebratory group photo. 

6 million drive units

The achievement was shared by the official Tesla Manufacturing account on social media platform X. “Congratulations to the Giga Nevada team for producing their 6 millionth Drive Unit!” Tesla wrote. 

The photo showed numerous factory workers assembled on the production floor, proudly holding golden balloons that spelled out “6000000″ in front of drive unit assembly stations. Elon Musk gave credit to the Giga Nevada team, writing, “Congrats on 6M drive units!” in a post on X.

Giga Nevada’s essential role

Giga Nevada produces drive units, battery packs, and energy products. The facility has been a cornerstone of Tesla’s scaling since opening, and it was the crucial facility that ultimately enabled Tesla to ramp the Model 3 and Model Y. Even today, it serves as Tesla’s core hub for battery and drivetrain components for vehicles that are produced in the United States.

Giga Nevada is expected to support Tesla’s ambitious 2026 targets, including the launch of vehicles like the Tesla Semi and the Cybercab. Tesla will have a very busy 2026, and based on Giga Nevada’s activities so far, it appears that the facility will be equally busy as well.

Tesla’s Supercharger Network had its biggest year ever in 2025, delivering a record 6.7 TWh of electricity to vehicles worldwide. 

To celebrate its busy year, the official @TeslaCharging account shared an infographic showing the Supercharger Network’s growth from near-zero in 2012 to this year’s impressive milestone.

Record 6.7 TWh delivered in 2025

The bar chart shows steady Supercharger energy delivery increases since 2012. Based on the graphic, the Supercharger Network started small in the mid-2010s and accelerated sharply after 2019, when the Model 3 was going mainstream. 

Each year from 2020 onward showed significantly more energy delivery, with 2025’s four quarters combining for the highest total yet at 6.7 TWh.

This energy powered millions of charging sessions across Tesla’s growing fleet of vehicles worldwide. The network now exceeds 75,000 stalls globally, and it supports even non-Tesla vehicles across several key markets. This makes the Supercharger Network loved not just by Tesla owners but EV drivers as a whole.

Resilience after Supercharger team changes

2025’s record energy delivery comes despite earlier 2024 layoffs on the Supercharger team, which sparked concerns about the system’s expansion pace. Max de Zegher, Tesla Director of Charging North America, also highlighted that “Outside China, Superchargers delivered more energy than all other fast chargers combined.”

Longtime Tesla owner and FSD tester Whole Mars Catalog noted the achievement as proof of continued momentum post-layoffs. At the time of the Supercharger team’s layoffs in 2024, numerous critics were claiming that Elon Musk was halting the network’s expansion altogether, and that the team only remained because the adults in the room convinced the juvenile CEO to relent.

Such a scenario, at least based on the graphic posted by the Tesla Charging team on X, seems highly implausible.
