What is Launch vehicle?
[[File:Soyuz TMA-5 launch.jpg|thumb|A Russian [[Soyuz (spacecraft)|Soyuz]] rocket launches from [[Baikonur Cosmodrome]] to the [[International Space Station]]]] A '''launch vehicle''' or '''carrier rocket''' is a [[rocket]] used to take a [[payload]] from Earth's surface [[Spaceflight|through outer space]]. This can be to another place on earth ([[Sub-orbital spaceflight|Sub-orbital transportation]]), or into space. Sub-orbital vehicles aren't as powerful as [[Orbit|orbital]] vehicles must be. They use more than one [[Multistage rocket|stage]] so that they have enough [[delta-v]] performance. Many different [[Rocket fuel|rocket fuels]] can be used, and some rockets have [[solid rocket boosters]] attached. Most launch vehicles are [[Expendable launch system|expendable,]] which means that they can only be used once. This means that lots of expensive equipment is lost, but it also means that the launch vehicle can carry a heavier payload.<ref>{{Cite web|url=http://spacetethers.com/elv.html|title=Expendable Launch Vehicles|website=spacetethers.com|access-date=2019-05-07}}</ref> [[Space Exploration Technologies Corporation|SpaceX]] has developed a partly reusable rocket, called the [[Falcon 9]]. It is also developing a fully reusable rocket called [[SpaceX Starship|Starship]]. The first stage of this rocket can land and be relaunched.<ref>{{Cite web|url=https://www.cnet.com/news/reused-spacex-falcon-9-rocket-makes-history-with-third-launch-and-landing/|title=Reused SpaceX Falcon 9 rocket makes history with third launch and landing|last=Mack|first=Eric|website=CNET|language=en|access-date=2019-05-07}}</ref> Parts of the [[Space Shuttle]] were also reusable.<ref>{{Cite web|url=https://www.space.com/16726-space-shuttle.html|title=Space Shuttle: The First Reusable Spacecraft|last=Spaceflight|first=Tim Sharp 2017-12-11T19:02:00Z|website=Space.com|language=en|access-date=2019-05-07}}</ref> There are many different types of launch vehicle. The vehicle that is used depends on the [[spaceport]], the mass of the payload, an
