SpaceX Starship V3 launch: SpaceX Starship V3 launch set this week: How to watch next-gen mega rocket test

SpaceX is gearing up for a major milestone this week with the launch of its next-generation Starship rocket, marking the first test flight of 2026 and a major step toward future SpaceX-led Moon and Mars missions. The mission is launching Starship Version 3, a significantly redesigned spacecraft that surpasses previous versions in scale and capability. When fully stacked with Super Heavy booster, the system has a height of just over 124 meters and a weight of almost 5,000 metric tons, making it the largest and most powerful rocket ever built in an overall comparison of scale; In fact, Big Ben in London is even bigger than the Elizabeth Tower. This flight also comes at a pivotal moment for SpaceX, which is reportedly preparing for a possible initial public offering (IPO) next month. The outcome of this test can shape the company’s technical roadmap as well as influence investor confidence.

Elon Musk has previously called the system “alien-level technology,” reflecting the intent behind the design and its complexity.

SpaceX Starship V3: A redesigned rocket for deep space missions

Starship Version 3 includes major structural upgrades that include expanded upper and booster stages to increase fuel capacity and payload performance. It also includes upgraded Raptor 3 engines.
The Super Heavy booster’s 33 engines are expected to produce almost 18 million pounds of thrust at liftoff; That’s more than twice the power of NASA’s Saturn V rocket used during the Apollo era. The rocket is being developed in partnership with NASA’s long-term lunar exploration plans under the Artemis initiative, with the hope that it could support manned lunar missions such as Artemis IV, now targeted for 2028. This mission focuses on returning astronauts to the Moon for the first time in more than 50 years.

NASA has already selected Starship as the leading option for a Moon landing, but delays in development could still affect timelines and future mission sequencing. Another competitor here is Blue Origin, which is developing the Blue Moon lunar lander.

Testing, upgrading and risks of SpaceX Starship V3

SpaceX stated that this was a highly experimental flight. The company mentioned in the company’s press release:
“The primary goal of flight testing will be to demonstrate each of these new parts in a flight environment for the first time.” He also confirmed that the booster will not return to heal this time:

“As this is the first flight test of a significantly redesigned vehicle, the booster will not attempt to return to the launch site for capture.”

The upgraded launch system on Starbase has better “chopsticks” used to catch returning boosters and is meant to increase rapid reuse on future missions.

How to watch SpaceX Starship V3 Launch

The launch will be livestreamed by SpaceX via various official channels, including its website, X (formerly Twitter) and YouTube.

• Live broadcast starts: ~45 minutes before departure
• Planned launch time: Thursday 21 May, 17:30 local time (23:30 BST)
• Watching platforms: SpaceX official website, X and YouTube channel

SpaceX is also planning behind-the-scenes coverage through its “Test as if you were flying” series that offers additional insight into launch preparations. However, timings remain flexible due to weather conditions or technical controls, meaning delays are possible until the final countdown.

If the flight is successful, Starship could move closer to supporting NASA’s Artemis 3 orbital operations and a potential Artemis 4 moon landing later this decade. Failure to do so could lead to further redesigns in one of the most ambitious rocket programs ever attempted.
