No rocket in history has generated more attention, controversy, or genuine excitement than SpaceX Starship. It is the tallest, most powerful, and most ambitious launch vehicle ever built — a fully reusable two-stage system designed not just to reach orbit, but to make space access cheap enough to eventually send humans to Mars. And as of 2026, it works.
This guide covers everything: what Starship actually is, how it compares to the rockets that came before it, the full history of every integrated flight test, what comes next, and how SatFleet Live lets you follow every Starship launch in real time — with a pulsing LIVE badge the moment the mission is underway.
What Is Starship?
Starship is a fully reusable two-stage launch vehicle developed by SpaceX. The system consists of two distinct hardware elements that together create the most capable rocket ever flown:
The Super Heavy booster is the first stage. It stands approximately 71 metres tall, is powered by 33 Raptor engines burning liquid methane and liquid oxygen, and generates over 74 meganewtons of thrust at liftoff. After separating from the upper stage, Super Heavy performs a boostback burn, re-enters the atmosphere, and returns to the launch site for mechanical capture by the "Mechazilla" tower — a process SpaceX calls a "catch."
The Ship is the upper stage and the spacecraft. It stands 50 metres tall, has 3 sea-level Raptor engines and 3 vacuum-optimised Raptors, and can carry up to ~100 tonnes of payload to low Earth orbit in its reusable configuration. Ship is designed to perform its own propulsive re-entry — belly-flop style — before reigniting its engines to land on either a landing pad or, eventually, the catch tower.
Starship is designed around one principle: full and rapid reusability. Unlike every rocket before it — including Falcon 9, which only recovers its first stage — Starship is intended to reuse both stages within hours of landing. SpaceX's target is a turnaround time similar to a commercial airliner, enabling a flight cadence that would make the cost per kilogram to orbit plummet from thousands of dollars to under $100.

How Starship Compares to Other Rockets
Numbers alone don't convey just how different Starship is from everything that preceded it. Here is a direct thrust comparison — the single metric that captures Starship's scale advantage most clearly:
The Raptor Engine
Super Heavy's performance comes from its 33 Raptor 2 engines — each one a highly refined iteration of SpaceX's full-flow staged combustion engine, the most thermodynamically efficient rocket engine cycle ever achieved in a production vehicle.
Raptor burns liquid methane (CH₄) and liquid oxygen (LOX) rather than the kerosene used by Falcon 9's Merlin engines. This choice is deliberate: methane can theoretically be synthesised on Mars from atmospheric CO₂ and subsurface ice ("in-situ resource utilisation"), enabling a self-sustaining refuelling ecosystem that SpaceX considers essential for a Mars colony.
Raptor 2 key performance numbers
| Parameter | Raptor 2 (sea level) | Raptor Vacuum |
|---|---|---|
| Thrust (sea level) | ~230 tf (2.26 MN) | N/A (vacuum only) |
| Thrust (vacuum) | ~250 tf (2.45 MN) | ~258 tf (2.53 MN) |
| Specific impulse (Isp) | ~327 s (SL) / ~350 s (vac) | ~380 s |
| Chamber pressure | >300 bar | >300 bar |
| Throttle range | ~40–100% | ~40–100% |
| Propellants | Liquid methane / liquid oxygen (full-flow staged combustion) | |
| Production cost | ~$250,000 (target at scale) | |
Raptor is one of the very few engines in history to achieve full-flow staged combustion — a cycle in which both propellants are pre-burned as oxidiser-rich and fuel-rich pre-burner gases before entering the main chamber. This eliminates the turbopump exhaust losses that limit simpler engines and pushes chamber pressure above 300 bar, enabling the extraordinary specific impulse (efficiency) and compact size that make Raptor remarkable. Soviet engineers achieved similar cycles in the RD-180 and NK-33; SpaceX has made it production-viable for the first time.
Mechazilla: The Tower That Catches Rockets
One of the most visually striking aspects of the Starship programme is its launch and integration tower — nicknamed "Mechazilla" by Elon Musk, officially called the Orbital Launch Mount integration tower. Standing roughly 146 metres tall, it serves as the rocket's integration facility, propellant loading station, and — most dramatically — its landing pad.
The tower's two massive actuated arms, informally called "chopsticks", are capable of mechanically catching a returning Super Heavy booster as it descends toward the tower. Rather than deploying landing legs and touching down on a pad (as Falcon 9 does), Super Heavy hovers and is grabbed mid-air by the arms, which then hold the booster upright.
The mechanical catch approach eliminates the need for landing legs on Super Heavy — saving several tonnes of structural mass that can instead be used as additional payload capacity. It also means the booster returns to the same tower used for stacking and launch, enabling faster turnaround: theoretically, Super Heavy could be re-stacked onto a new Ship within hours of a catch. As SpaceX says, the tower is the launch pad, the integration facility, and the landing pad simultaneously.
The first successful mechanical booster catch was achieved during IFT-5 in October 2024 — a historic moment that many engineers consider more technically significant than the first Starship orbital flight. SpaceX is now working toward eventually catching Ship as well, though as of early 2026, Ship still lands at sea or on a designated pad.
Full Flight Test History
Starship has gone from catastrophic pad destruction on its first flight to routine booster catches in just over two years — a development pace unlike anything seen in rocket engineering history.

Next Starship Launch: When and How to Watch
Starship launch dates are typically confirmed a few weeks in advance and can slip due to weather, hardware readiness, or FAA licensing. The most reliable source for the current target date is the SatFleet Live Launches page, which pulls live data from the Launch Library 2 API and updates automatically with countdowns, pad location, and status badges.
How to watch Starship live
SpaceX streams every Starship flight test for free on its YouTube channel (youtube.com/spacex). Coverage typically begins 30–45 minutes before the opening of the launch window and continues through stage separation, booster catch attempts, and Ship re-entry. For major tests, SpaceX often provides additional camera feeds — including cameras mounted on the Mechazilla arms catching the booster.
Starship launches from Starbase in Boca Chica, Texas. Launch windows are typically approximately 1 hour long, opening at a time determined by the mission profile. Unlike Falcon 9 — which launches every few days — Starship flights are more spaced out: the current cadence is roughly one flight every 4–8 weeks as SpaceX prepares, refurbishes, and improves hardware between flights.
What Will Starship Be Used For?
Starship is not built for a single mission. SpaceX envisions it as a universal launch platform capable of replacing every other rocket in their fleet — and eventually enabling missions no rocket has ever attempted.
Near-term: Starlink V3 deployment
The most immediate operational use for Starship is deploying second-generation Starlink satellites (Gen 2 / V3). These satellites are significantly larger and more capable than the V1.5 versions Falcon 9 carries — too large for Falcon 9's fairing. A single Starship launch can deploy a full batch of ~100+ Gen 2 Starlinks, versus 22–23 for Falcon 9. This is the primary commercial driver behind SpaceX's urgency to make Starship operational in 2026.
Commercial and government payloads
Starship's massive payload bay (9 m diameter, ~18 m usable length) can carry payloads too large for any existing fairing. This opens the market for monolithic telescope mirrors, large space station modules, and high-capacity communications satellites that previously had to be divided across multiple launches.
NASA Artemis — Human Landing System
In April 2021, NASA selected Starship as the Human Landing System (HLS) for the Artemis programme — the vehicle that will carry astronauts from lunar orbit to the surface of the Moon for the first time since Apollo 17. Starship HLS is a modified version of Ship with extended landing legs and a crew elevator. It does not need to land and launch from Earth — it will be refuelled in lunar orbit by propellant-transfer missions.
Mars and beyond
Elon Musk has stated from the beginning that Starship exists to make humanity multiplanetary. The long-term vision is a fleet of Starships capable of carrying 100+ passengers on Earth-to-Mars trajectories during each launch window — approximately every 26 months. The methane propellant is specifically chosen because it can be produced on Mars, enabling round-trip missions without pre-positioning fuel from Earth.
Tracking Starship on SatFleet Live
SatFleet Live integrates Starship into its launch tracking system in two ways: before launch and after payload deployment.
Before launch: pad marker and countdown
When a Starship flight is scheduled, a SpaceX rocket icon appears pinned to the Starbase launch pad at Boca Chica, Texas on both the 2D map and the 3D globe. Clicking or tapping the icon opens an info panel with the mission name, countdown, and a direct link to the Launches page. When the mission goes live — triggered by the webcast starting or the status switching to "In Flight" — the icon switches to a pulsing red LIVE badge.
After deployment: tracking Starlink V3 satellites
When Starship deploys a Starlink batch, the new satellites appear on SatFleet Live within 24–48 hours as NORAD publishes their tracking data. Because Starship delivers more satellites per flight than Falcon 9, a new Starship-deployed batch will produce a noticeably larger and brighter cluster — visible as a Starlink train in the days after launch. Use the Layers panel to filter for Starlink and watch the new batch appear, then raise its orbit from ~300 km to 550 km over the following weeks.
