Launch history

Every launch of the last thirty days, newest first: how each one went, what became of the booster, and the flight itself, replayed on the globe.

    Launches, results and recovery records from Launch Library 2 by The Space Devs. Times in your own time zone. The replays are the site's own flight model, timed to each mission's published events.

    Space history

    From Sputnik to Starship: the space race, the firsts, the lives lost and the machines that made it all possible, 1957 to today. Open any moment for the real photographs and film, the rocket that flew it — how many tries it took and how it failed — and what it cost, then and in today’s money.

    Every orbital launch vehicle currently flying, being built, or recently retired — and the full Starship variant tree, which no launch API carries. Live launch counts and photographs are merged in from the schedule.

    Starship

    The next flight of the largest rocket ever built, tracked from the hardware up: which preparation milestones each vehicle has cleared, what is left before it can fly, and the live stream when it does.

    The checklist

    Next Spaceflight's checklist for this flight, item for item. A box ticks here when they confirm it, usually within half an hour.

    – milestones confirmed

    Unticked doesn't mean not started. SpaceX doesn't publish a test schedule, so an item only ticks once it has been publicly confirmed. The work is usually further along than that.

    Every test Next Spaceflight has logged for this flight's booster and ship, newest first.

    Vehicle

    Starship V3, by the numbers

    Full stack: Super Heavy booster plus Starship upper stage, both designed to return to the tower and fly again.

    Height, stacked
    124.4m 408 ft — taller than the Saturn V by 13 m
    Liftoff mass
    5,300t Fuelled and stacked, roughly the mass of 8 fully loaded 747s
    Liftoff thrust
    90.6MN ≈ 9,240 tf — about 2.6× the Saturn V
    Engines
    39 33 Raptor 3 on the booster, 6 on the ship (3 sea-level, 3 vacuum)
    Payload to LEO
    100t + Fully reusable; 180–200 t if the vehicle is expended
    Propellant load
    4,600t Subcooled liquid oxygen and liquid methane, both stages
    Propellant

    What it takes to fill it

    A Starship is mostly a tank of oxygen. The engines burn methane at a mixture ratio near 3.6 parts oxygen to one part fuel, so the oxidiser dominates both the mass and the bill.

    Liquid oxygen · ≈3,600 t Liquid methane · ≈1,000 t

    Loaded in roughly an hour through the tower's quick-disconnect arm. The methane alone releases, when burned, about as much energy as the daily primary energy use of a city of 345,000 people — spent in under seven minutes of powered flight.

    • Liquid oxygen, ≈3,600 t≈ $0.6–1.1 M
    • Liquid methane, ≈1,000 t≈ $0.4–0.9 M
    • Implied blended price≈ $220–435 / t
    • Fuel share of a 100 t payload≈ $10–20 / kg
    • Total to fuel one flight≈ $1–2 M

    Propellant cost is an estimate, not a published figure: SpaceX does not disclose what it pays, and industrial gas is bought on long contracts at prices that move with natural gas and electricity. The $1–2 M range is the one most commonly cited for a full stack in 2026; Musk's long-stated target of $100 per tonne would put it nearer $0.5 M. Either way the fuel is the small number — for context, a Falcon 9 launch sells for about $70 M, and the propellant in it costs under $200,000.

    The checklist, the booster and ship, and the test log come from Next Spaceflight's Starship page. Launch dates and the countdown come from the Launch Library 2 API.

    Size compare

    How big is it, really?

    Every rocket in the fleet and famous ones from history, their engines, boosters and grid fins, spacecraft, space stations, satellites and rovers, landmarks and everyday things, standing side by side at true scale. Type a name to add it to the line-up, as many as you like.

    Loading the line-up…

    Every picture is drawn by Rocket Tracker from published heights and diameters, so widths are to scale as well as heights. Rockets stand as they do on the pad; vehicles, rovers, the whale and the T. rex lie at their full length; space stations and satellites are seen from above with their wings out. Where a maker has never published a size, the label says "about".
