The following chart shows the number of launch systems developed in each country, and broken down by operational status. Rocket variants are not distinguished; i.e., the Atlas V series is only counted once for all its configurations 401–431, 501–551, 552, and N22.

The earliest space vehicles were expendable launch systems, using a single or multistage rocket to carry a relatively small spacecraft in proportion to the total vehicle size and mass. [1] An early exception to this, the Space Shuttle , consisted of a reusable orbital vehicle carrying crew and payload, supported by an expendable external ...
The rocket would be built at a sea-side shipbuilder and towed to sea for launch. It would use wide engineering margins with strong simple materials to further enhance reliability and reduce cost and complexity. The system would be at least partially reusable with passive reentry and recovery of rocket sections for refurbishment and relaunch. [3 ...
An autonomous spaceport drone ship (ASDS) is a modified ocean-going barge equipped with propulsion systems to maintain precise position and a large landing platform. SpaceX developed these vessels to recover the first stage (also called the booster) of its launch vehicles.
A super heavy-lift launch vehicle is a rocket that can lift to low Earth orbit a "super heavy payload", which is defined as more than 50 metric tons (110,000 lb) [1] [2] by the United States and as more than 100 metric tons (220,000 lb) by Russia. [3]
ULA prices to the US government are nearly $400 million for current launches of Falcon 9- and Falcon Heavy-class payloads. [ 64 ] [ needs update ] SpaceX had a rare coincidence of four rockets (all types of operational and under-development rockets) on all four of its orbital launch pads and two Dragon 2s (both types of Dragon 2s) on orbit on ...
The core stage was shipped to Kennedy Space Center to be mated with the rest of the rocket for Artemis I. It left Stennis on 24 April and arrived at Kennedy on 27 April. [152] It was refurbished there in preparation for stacking. [153] On 12 June 2021, NASA announced the assembly of the first SLS rocket was completed at the Kennedy Space Center.
