SpaceX launching Starship Flight 13 test mission today: Watch it live
SpaceX’s Starship megarocket will take to the skies again today (July 16), and you can watch the thundering action live.
Starship, the biggest and most powerful rocket ever built, is scheduled to lift off from SpaceX’s Starbase site in South Texas today — the 57th anniversary of the launch of NASA’s Apollo 11 moon mission, by the way — during a 90-minute widow that opens at 6:45 p.m. EDT (2245 GMT; 5:45 p.m. local Texas time). It will be Starship’s 13th flight overall and its second mission of 2026.

A potentially revolutionary rocket
Starship consists of a first-stage booster called Super Heavy and an upper-stage vehicle known (somewhat confusingly) as Starship, or simply Ship. Both elements are made of stainless steel and are designed to be fully and rapidly reusable.
The stacked vehicle stands more than 400 feet (122 meters) tall and can carry more than 110 tons (100 metric tons) to Earth orbit. SpaceX thinks Starship’s combination of power and reusability will revolutionize spaceflight, allowing humanity to settle the moon and Mars, among other bold exploration feats.
Starship debuted in April 2023 and has flown 11 more suborbital flights since, most recently on May 22. That Flight 12 test was the first mission for Starship Version 3 (V3), an advanced iteration of the megarocket that was many months in the making. (Flight 11, the last launch of Starship V2, lifted off in October 2025.)
Starship V3 will be the first operational variant of the vehicle. It will fly on NASA’s Artemis III mission to Earth orbit in 2027, for example, and land the agency’s Artemis IV astronauts on the moon a year later, if all goes to plan.
Starship V3 performed quite well during its launch debut in May. During Flight 12, Ship successfully deployed 22 payloads via its “PEZ dispenser” slit — 20 dummy versions of SpaceX’s Starlink broadband satellites and two actual Starlinks equipped with imaging sensors — and came back to Earth in one piece, splashing down as planned off the coast of Western Australia.
There were a few hiccups, however. Super Heavy suffered engine issues during its return to Earth, for instance, and ended up crashing in the Gulf of Mexico rather than making a controlled splashdown there.
SpaceX will run it back on Flight 13, shooting mostly for the same objectives that Flight 12 targeted — with a few notable exceptions.
The plan for Starship Flight 13
Eventually, SpaceX plans to return both Super Heavy and Ship directly to the launch pad after liftoff, catching each with the “chopstick” arms attached to Starbase’s two launch towers. (Starship will also fly from Florida and perhaps other places as well in the coming years; these future pads will have chopstick arms, too.) This strategy will allow each vehicle to fly multiple times per day, according to the company.
SpaceX has caught Super Heavy three times to date, but it’s been a while; the last such snag came on Flight 8 in March 2025. And the company has never tried a chopsticks catch with Ship.
Those trends will continue on Flight 13. If all goes to plan, Super Heavy will steer its way to a controlled splashdown in the Gulf of Mexico (which the Trump administration has renamed the Gulf of America) about seven minutes after launch.
“The booster’s primary test objective will be executing a successful launch, ascent, stage separation, boostback burn and landing burn at an offshore landing point in the Gulf of America,” SpaceX wrote in a Flight 13 mission description. “There have been several modifications to hardware and software to address issues seen on the previous flight.”
Ship will again target a splashdown in the Indian Ocean off the coast of Western Australia, which will occur about 65 minutes after launch. And the vehicle will again deploy some objects into suborbital space — but here’s where Flight 13 will break new ground.
Those objects will be 20 V3 Starlink satellites — next-gen versions of the broadband spacecraft, which will “greatly expand the network’s capacity and user speeds,” SpaceX wrote in the mission description.
Eventually, SpaceX wants to operate up to 100,000 V3 Starlinks in low Earth orbit — a bold plan, considering that the current megaconstellation, the largest such network ever assembled, contains “only” about 10,800 spacecraft.
The Starlink V3 plan will require thousands of launches — a load that’s beyond even the capabilities of SpaceX’s workhorse Falcon 9 rocket, which flew 165 times in 2025. (Adding to the difficulty: Starship V3 satellites are considerably heavier than their predecessors. Each one will apparently weigh around 4,400 pounds, or 2,000 kilograms.)
The 20 Starlink V3 satellites “will extend solar arrays and antennas and will attempt to connect with the larger Starlink constellation via high-capacity lasers,” SpaceX wrote in the Flight 13 description. “The Starlink satellites will be on the same suborbital trajectory as Starship and are expected to demise upon reentry approximately 20 minutes after deployment.”
Six of the 20 spacecraft are equipped with cameras, which they will use to scan and study Ship’s heat-shield tiles. SpaceX wants to gather more data about the heat-shield system before it attempts to bring Ship back to the launch pad for a chopsticks catch.
And SpaceX won’t just passively observe the heat shield during Flight 13; it will conduct some experiments as well.
For example, the shield “will have load-sensing tiles to take measurements as the vehicle experiences higher dynamic pressure on ascent than previous flights, putting added stress on the tile attachments in exchange for increased payload-to-orbit capability,” the mission description reads.
So there will indeed be some new things to look out for during Flight 13. And watching the world’s biggest and brawniest rocket lift off is a treat no matter what sort of mission it’s flying, so be sure to tune in today!
