'''Splashdown''' is the method of landing a spacecraft or launch vehicle in a body of water, usually by parachute. This has been the primary recovery method of American capsules including NASA's Mercury, Gemini, Apollo and Orion along with the private SpaceX Dragon. It is also possible for the Boeing Starliner, Russian Soyuz, and the Chinese Shenzhou crewed capsules to land in water in case of contingency. NASA recovered the Space Shuttle solid rocket boosters (SRBs) via splashdown, as is done for Rocket Lab's Electron first stage.

As the name suggests, the vehicle parachutes into an ocean or other large body of water. Due to its low density and viscosity, water cushions the spacecraft enough that there is no need for a braking rocket to slow the final descent as is the case with Russian and Chinese crewed space capsules or airbags as is the case with the Starliner.<ref name="Prof Tous">{{cite web |last1=Tous |first1=Marcos |title=The science behind splashdown—aerospace engineer explains how NASA and SpaceX get spacecraft safely back |date = 28 June 2024|url=https://theconversation.com/the-science-behind-splashdown-an-aerospace-engineer-explains-how-nasa-and-spacex-get-spacecraft-safely-back-on-earth-232786 |website=The Conversation |access-date=27 November 2024}}</ref>

The American practice came in part because American launch sites are on the coastline and launch primarily over water.<ref>{{cite web|url=https://www.nasa.gov/centers/kennedy/launchingrockets/sites.html |title=Launch Services Program Launch Sites |publisher=NASA |date=2009-05-14 |access-date=2020-08-07}}</ref> Russian launch sites such as Baikonur Cosmodrome are far inland, and most early launch aborts would descend on land.

==History== [[File:Apollo14 - Landung.jpg|thumb|left|Apollo 14 returns to Earth, 1971.]] The splashdown method of landing was used for Mercury, Gemini, and Apollo (including Skylab, which used Apollo capsules) missions, and is used for Artemis missions.

On early Mercury flights, a helicopter attached a cable to the capsule, lifted it from the water and delivered it to a nearby ship. This was changed after the sinking of ''Liberty Bell 7''. All later Mercury, Gemini and Apollo capsules had a flotation collar (similar to a rubber life raft) attached to the spacecraft to increase their buoyancy. The spacecraft would then be brought alongside a ship and lifted onto deck by crane.

After the flotation collar is attached, a hatch on the spacecraft is usually opened. At that time, some astronauts decide to be hoisted aboard a helicopter for a ride to the recovery ship and some decided to stay with the spacecraft and be lifted aboard ship via crane. All Gemini and Apollo flights (Apollos 7 to 17) used the former, while Mercury missions from Mercury 6 to Mercury 9, as well as all Skylab missions and Apollo-Soyuz used the latter, especially the Skylab flights as to preserve all medical data. During the Gemini and Apollo programs, NASA used {{MV|Retriever}} for the astronauts to practice water egress.

Apollo 11 was America's first Moon landing mission and marked the first time that humans walked on the surface of another planetary body. The possibility of the astronauts bringing pathogens from the Moon back to Earth was remote, but not ruled out. To contain any possible contaminants at the scene of the splashdown, the astronauts donned special Biological Isolation Garments and the outside of the suits were scrubbed prior to the astronauts being hoisted aboard {{USS|Hornet|CV-12|6}} and escorted safely inside a Mobile Quarantine Facility.<ref>{{cite web |url=http://www.uss-hornet.org/history/apollo/ |title=Apollo 11 & 12 Recovery |author=Bob Fish |publisher=USS Hornet Museum's website}}</ref> thumb|261x261px|The splashdown of the SpaceX CRS-25 resupply mission Both the SpaceX Dragon 1 and Dragon 2 capsules were designed to use the splashdown method of landing.{{efn|Dragon 2 was originally intended to propulsively land using its SuperDraco engines, but this was abandoned except for contingency in case of parachute failure.<ref>{{cite web |last1=McRea |first1=Aaron |title=Dragon receives long-planned propulsive landing upgrade after years of development |url=https://www.nasaspaceflight.com/2024/10/dragon-propulsive-landing/ |website=Nasa Spaceflight |date=October 10, 2024 |access-date=11 November 2024}}</ref>}} The original cargo Dragon splashed down in the Pacific Ocean off the coast of Baja California.

The early design concept for Orion (then known as the Crew Exploration Vehicle) featured recovery on land using a combination of parachutes and airbags, although it was also designed to make a contingency splashdown if needed. Due to weight considerations, the airbag design concept was dropped for Orion, and it conducts landings via splashdown in the Pacific Ocean off the coast of California.<ref>{{cite web|url=http://solarsystem.nasa.gov/news/display.cfm?News_ID=37403 |archive-url=https://web.archive.org/web/20110703185450/http://solarsystem.nasa.gov/news/display.cfm?News_ID=37403 |url-status=dead |archive-date=2011-07-03 |title=Solar System Exploration: News & Events: News Archive: NASA Announces Key Decision For Next Deep Space Transportation System |publisher=Solarsystem.nasa.gov |date=2011-05-24 |access-date=2012-06-21}}</ref>

==Disadvantages== Perhaps the most dangerous aspect is the possibility of the spacecraft flooding and sinking. For example, when the hatch of Gus Grissom's ''Liberty Bell 7'' capsule blew prematurely, the capsule sank and Grissom almost drowned. Since the spacecraft's flooding will occur from a location in its hull where it ruptures first, it is important to determine the location on the hull that experiences the highest loading.<ref>{{cite journal|last=Jain|first=U.|display-authors=et al.|journal=Journal of Fluid Mechanics|date=2021|volume=938|issue=4|title=Air entrapment and its effect on pressure impulses in the slamming of a flat disc on water |article-number= A31 |doi=10.1017/jfm.2021.846| arxiv=2012.10137|bibcode=2021JFM...928A..31J }}</ref> This location along the impacting side is determined by the surrounding 'air cushion' layer, which deforms the water surface before the moment of impact, and results in a non-trivial geometry of the liquid surface during first touch-down.<ref>{{cite journal|last=Jain|first=U.|display-authors=et al.|journal=Physical Review Fluids|date=2021|volume=6|issue=4|title=Air-cushioning effect and Kelvin-Helmholtz instability before the slamming of a disk on water |article-number= L042001 |doi=10.1103/PhysRevFluids.6.L042001|arxiv= 2106.09551|bibcode=2021PhRvF...6d2001J }}</ref><ref>{{cite journal|last=Verhagen|first=J.H.G|journal= Journal of Ship Research|year=1967|title=The Impact of a Flat Plate on a Water Surface|volume=11 |issue=4 |pages=211–223 |doi=10.5957/jsr.1967.11.4.211 |url=https://archive.org/details/Verhagen1967}}</ref><ref>{{cite journal|last= Asryan |first=N.G.|journal= Izv.

If the capsule comes down far from any recovery forces, the crew may be stranded at sea for an extended period of time. As an example, Scott Carpenter in ''Aurora 7'' overshot the assigned landing zone by {{convert|400|km|sp=us}}. These recovery operation mishaps can be mitigated by placing several vessels on standby in different locations, but this can be an expensive option.

SpaceX has conducted propulsive splashdowns of the Falcon 9 first stage, Super Heavy booster, and Starship spacecraft. These vehicles are designed to land on land or modified barges and do not always survive intact after tipping over in the water; SpaceX has mainly conducted propulsive splashdowns for development flights. After the launch of CRS-16, the booster experienced a control issue and splashed down in the ocean instead of making an intended landing at Landing Zone 1.<ref name="NSF CRS-16">{{cite web |last1=Bergin |first1=Chris |date=13 January 2019|title=CRS-16 Dragon returns to Earth following ISS departure |url=https://www.nasaspaceflight.com/2019/01/crs-16-dragon-departs-iss-return-journey/ |website=NASA Spaceflight |access-date=27 November 2024}}</ref>
