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.

🏗️ The philosophy

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.

Throttle range~40–100%~40–100%
PropellantsLiquid methane / liquid oxygen (full-flow staged combustion)
Production cost~$250,000 (target at scale)
🔥 Full-flow staged combustion

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.

🎯 Why catch instead of land?

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.

IFT-1
Apr 2023
First integrated flight test — clears the pad Partial success
The first ever flight of the fully integrated Starship/Super Heavy system. The vehicle cleared the pad at T+0 — SpaceX's primary objective — and flew for approximately 4 minutes before an unplanned rapid disassembly at Max-Q. Significant pad damage occurred. SpaceX called it a success: the vehicle flew, and data was collected. The entire launch pad infrastructure was redesigned as a result.
IFT-2
Nov 2023
Hot staging and higher altitude Partial success
SpaceX introduced hot staging — igniting Ship's engines before Super Heavy separation — dramatically improving second-stage performance. The vehicle reached near-space velocities. Super Heavy was lost during its return burn attempt; Ship reached near-orbital speed before being lost during controlled descent. The new pad infrastructure with a water-cooled steel plate held perfectly.
IFT-3
Mar 2024
First near-full flight trajectory Major success
Both stages flew their full intended trajectories. Super Heavy performed a controlled ocean splashdown. Ship re-entered the atmosphere, survived to near-intact before being lost during final descent. First demonstration of Ship's active heat shield tiles surviving re-entry heating. SpaceX declared this the most successful test to date.
IFT-4
Jun 2024
Ship controlled ocean landing achieved Full success
Both stages performed clean splashdowns in the ocean — Super Heavy in the Gulf of Mexico, Ship in the Indian Ocean. Ship survived re-entry with its heat shield largely intact and performed a controlled flip-and-burn landing burn, touching down softly in the ocean. First demonstration of end-to-end Starship mission profile.
IFT-5
Oct 2024
First mechanical booster catch Historic record
SpaceX achieved the first-ever mechanical catch of a returning orbital rocket booster using the "chopstick" arms of the Mechazilla tower. Super Heavy returned to the launch site and was captured perfectly. Ship performed its second successful ocean splashdown. The booster catch is widely considered one of the most technically significant events in spaceflight history.
IFT-6
Nov 2024
Second booster catch, Ship payload bay demo Full success
Super Heavy was caught again by the tower arms. Ship opened its payload bay door in orbit, demonstrating the hardware for future satellite deployments. Ship again performed a successful controlled ocean entry. SpaceX demonstrated catching the booster twice in rapid succession, validating the hardware as operationally reliable.
IFT-7+
2025–2026
Transition to operational flights Ongoing
Subsequent flights have continued maturing the system — working toward Ship catch by the tower, higher reuse rates, and eventually the first operational Starlink V3 batch deployments. SpaceX is also preparing for NASA's Artemis Human Landing System (HLS) contract, which requires Starship to deliver astronauts to the lunar surface.

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.

📡 When is the launch window?

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.

Frequently Asked Questions

The current target date is on the SatFleet Live Launches page with a live countdown. Starship launches roughly every 4–8 weeks as SpaceX prepares and improves hardware between flights. Dates are confirmed a few weeks in advance and can shift due to FAA licensing or hardware checks. In 2026, SpaceX is transitioning from flight testing to early operational missions.
Fully integrated, Starship stands 121 metres (397 feet) — the Super Heavy booster at ~71 m plus the Ship at ~50 m. This makes it the tallest rocket ever to fly, surpassing the Saturn V (111 m) by 10 metres. For reference, it is about twice the height of the Statue of Liberty.
Super Heavy's 33 Raptor 2 engines generate approximately 74.4 meganewtons (16.7 million lbf) of thrust at liftoff — about double the Saturn V's 35 MN. This makes Starship by far the most powerful launch vehicle ever flown. Each individual Raptor 2 produces roughly 230 tonnes-force (≈2.26 MN) at sea level.
Yes. As of 2026, SpaceX has completed multiple successful integrated Starship flight tests. The programme progressed from pad destruction (IFT-1, 2023) to routine booster catches (IFT-5/6, late 2024) in under two years. IFT-5 in October 2024 achieved the first mechanical catch of a returning booster — one of the most significant milestones in spaceflight history. SpaceX is now working toward early operational missions.
All current Starship flights launch from Starbase in Boca Chica, Texas — SpaceX's purpose-built launch facility near Brownsville. SpaceX is also building a second Starship launch mount at Kennedy Space Center's Launch Complex 39A in Florida, which is expected to support higher launch cadences once operational. Both sites are shown on the SatFleet Live map.
"Mechazilla" is the nickname for Starbase's Orbital Launch Mount integration tower — a 146-metre steel structure with two massive actuated arms ("chopsticks") that mechanically catch the returning Super Heavy booster. Instead of landing on legs like Falcon 9, Super Heavy hovers and is grabbed mid-air by the tower arms. The first successful catch occurred during IFT-5 in October 2024. SpaceX is now working toward catching Ship the same way.
The primary near-term use is deploying Starlink Gen 2 (V3) satellites — batches of 100+ per flight versus 22 for Falcon 9. Beyond that: commercial satellite launches, NASA's Artemis Human Landing System (the vehicle that will land astronauts on the Moon), and in the long term, crewed missions to Mars. SpaceX's stated target is a cost below $100/kg to orbit at full reusable cadence.
Methane (CH₄) was chosen for two main reasons. First, it produces higher specific impulse (efficiency) than kerosene in a full-flow staged combustion engine. Second — and uniquely important to SpaceX's long-term vision — methane can theoretically be produced on Mars from atmospheric CO₂ and water ice ("Sabatier reaction"), enabling a self-sustaining fuel production loop that eliminates the need to launch return propellant from Earth. Kerosene has no practical in-situ production pathway on Mars.
