The duration of the rocket launch animation is 2420 [[Time#Ticks|game-tick]]s, or 40.33 seconds [https://www.reddit.com/r/technicalfactorio/comments/f753iu/empirical_measurements_on_the_silo_animation/fibsvn6/]. This is the time from when the rocket is finished to when production on the next rocket can start, but does not include the time to insert the payload. Unlike rocket part crafting, the animation's duration is not affected by any modules or beacons. This may become a factor if one is planning to launch rockets at high frequency.
A fully moduled silo has +940% crafting speed from beacons and +40% productivity. Modules accelerate crafting time in the first phase, but have no effect on animations in the other phases.  


The shortest crafting time achievable for 100 rocket parts in a single silo is ~20.60 seconds; i.e., slightly longer than what would be required to launch 1 rocket / minute. This crafting time is achieved using the maximum of 20 beacons with all [[speed module 3|speed modules 3]], plus 4 [[productivity module 3|productivity modules 3]] in the silo itself. The latter not only cuts resource requirements by almost 30%, but is also faster than using more speed modules 3 in the silo.
There are four phases to a rocket launch.  


For automated rocket launches, the insertion time of the satellite has to be considered. An inserter requires half a turn to insert the satellite, which takes 13 ticks (0.22 seconds), assuming a fast/stack inserter is used. Thus, the largest automated space science pack output one can obtain out of a single rocket silo is about 981 per minute. (<code>~= 1000 × 60 ÷ (40.33 + 20.60 + 0.22)</code>‬)

Player.png

The Rocket silo is currently the only win condition. Once the silo has been built and placed it can be filled with low density structures, rocket fuel, and rocket control units, which will allow rocket parts to be created within the silo.

In order to launch a rocket, 100 rocket parts need to be crafted. Each rocket part requires 10 low density structures, 10 rocket fuel, and 10 rocket control units.

When all rocket parts have been completed, the rocket silo interface is at 100% and allows the player to input an item as cargo. Launching the rocket empty or with any payload will complete the game, displaying a victory screen. The screen shows all kills and time played, and offers the player a choice of exiting the current game, continuing play, or viewing the replay.

Launching the rocket with a satellite as cargo produces 1000 space science packs, which are generated inside the silo. The silo interface includes the option to "Auto-launch with cargo", which will immediately, automatically launch the rocket if it is completed and cargo has been inserted as payload.

Building a silo requires, among other things, electric engine units, engine units, and processing units, which must be produced in assembling machines and cannot be crafted by hand from raw materials. The rocket itself can also only be produced in the silo. The rocket silo accepts productivity modules, and due to the high resource requirements to craft a rocket is a good candidate for their use.

The rocket silo result inventory can hold up to 2000 space science packs (one stack), the equivalent of 2 full rocket launch results. When receiving science packs from a launched satellite, the game discards (destroys) all space science packs that exceed the capacity of the rocket result inventory. The "Auto launch with cargo" checkbox does not check if the rocket result inventory can hold the expected space science packs, this has to be manually ensured by the player, for example through the circuit network.

Maximum throughput

A fully moduled silo has +940% crafting speed from beacons and +40% productivity. Modules accelerate crafting time in the first phase, but have no effect on animations in the other phases.

There are four phases to a rocket launch.

Working

Rocket parts must be assembled in the silo before the rocket can be deployed.

The best possible time to assemble 100 rocket parts, based on the rocket part recipe and the module effects, is 1250 ticks, or ~20.833 seconds.

1250 ticks elapsed.

Preparing rocket for launch

The rocket is brought up out of the silo so a payload can be inserted, if any.

This animation lasts 890 ticks, or ~14.833 seconds.

2140 ticks elapsed.

Waiting to launch rocket

The payload must be inserted.

One fast inserter arm swing to insert a Satellite is 14 ticks, or ~0.233 seconds.

2154 ticks elapsed.

Launching rocket

The rocket is launched with the payload. This phase ends when the result inventory appears inside the silo.

1162 ticks, or ~19.367 seconds.

3316 ticks elapsed.

Reset

The silo door must close before the cycle begins again.

368 ticks, or ~6.133 seconds.

Conclusions

Grand Total: 3684 ticks, which gives a total cycle time of ~61.417 seconds, including time spent building rocket parts and inserting the payload.

With a build time of 1250 + 14, the delay from animations is 2420 ticks.[1]

Trivia

The rocket can, technically, accept any item as cargo; however, most will do nothing in particular and simply waste the launch. Notable exceptions include:
