A '''sounding rocket''' or '''rocketsonde''', sometimes called a '''research rocket''' or a '''suborbital rocket''', is an instrument-carrying rocket designed to take measurements and perform scientific experiments during its [[sub-orbital spaceflight|sub-orbital]] flight. The rockets are often used to launch instruments from 48 to 145&nbsp;km (30 to 90 miles)<ref>[http://sites.wff.nasa.gov/code810/files/SRHB.pdf nasa.gov] NASA Sounding Rocket Program Handbook, June 2005, p. 1 ([https://web.archive.org/web/20241223111544/https://sites.wff.nasa.gov/code810/files/SRHB.pdf Archive link], December 2024)</ref> above the surface of the Earth, the altitude generally between [[weather balloon]]s and [[satellite]]s; the maximum altitude for balloons is about 40&nbsp;km (25 miles) and the minimum for satellites is approximately 121&nbsp;km (75 miles).<ref name="overview">{{cite web |date=24 July 2006 |title=NASA Sounding Rocket Program Overview |url=http://rscience.gsfc.nasa.gov/srrov.html |archive-url=https://web.archive.org/web/20241127192630/http://rscience.gsfc.nasa.gov/srrov.html |archive-date=27 November 2024 |access-date=10 October 2006 |work=NASA Sounding Rocket Program |publisher=NASA}}</ref>

Due to their suborbital flight profile, sounding rockets are often much simpler than counterparts built for orbital flight.<ref name="overview" /> Certain sounding rockets have an [[apogee]] between 1,000 and 1,500&nbsp;km (620 and 930 miles), such as the [[Black Brant (rocket)|Black Brant X and XII]], which is the maximum apogee of their class. For certain purposes, sounding rockets may be flown to altitudes as high as 3,000 kilometers (1860 miles) to allow observing times of around 40 minutes to provide geophysical observations of the magnetosphere, ionosphere, thermosphere and mesosphere.<ref name="highaltitude">{{cite web |date=29 September 2024 |title=High Altitude Sounding Rocket |url=https://rscience.gsfc.nasa.gov/keydocs/HASR_Slides.pdf |archive-url=https://web.archive.org/web/20241127192906/https://rscience.gsfc.nasa.gov/keydocs/HASR_Slides.pdf |archive-date=27 November 2024 |access-date=29 September 2024 |work=NASA Sounding Rocket Program |publisher=NASA}}</ref>

==Etymology==
The origin of the term comes from nautical vocabulary ''to [[Depth sounding|sound]]'', which is to throw a weighted line from a ship into the water to measure the water's depth. The term itself has its etymological roots in the [[Romance languages]] word for ''probe'', of which there are nouns ''[[wiktionary:sonda|sonda]]'' and ''[[wiktionary:sonde|sonde]]'' and verbs like ''[[wiktionary:sondar|sondar]]'' which means "to do a survey or a poll". ''Sounding'' in the rocket context is equivalent to "taking a measurement".<ref name="what">{{cite web |last=Marconi |first=Elaine M. |date=12 April 2004 |title=What is a Sounding Rocket? |url=http://www.nasa.gov/missions/research/f_sounding.html |archive-url=https://web.archive.org/web/20191003171315/https://www.nasa.gov/missions/research/f_sounding.html |archive-date=3 October 2019 |access-date=10 October 2006 |work=Research Aircraft |publisher=NASA}}</ref>

== Design ==
[[File:SoundingRocketSamplePayload-02.jpg|thumb|right|upright|Sample payloads for sounding rockets]]
The basic elements of a modern sounding rocket are a [[solid-fuel rocket]] motor and a science [[Payload (air and space craft)|payload]].<ref name=what/> In certain sounding rockets the payload may even be nothing more than a smoke trail as in the [[Nike Smoke]] which is used to determine wind directions and strengths more accurately than may be determined by [[weather balloons]]. Or a sounding rocket such as the [[Nike-Apache]] may deposit sodium clouds to observe very high altitude winds. Larger, higher altitude rockets have multiple [[rocket staging|stages]] to increase altitude and/or payload capability. The [[freefall]] part of the flight is an [[elliptic orbit|elliptic trajectory]] with vertical [[Semi-major axis|major axis]] allowing the payload to appear to hover near its [[apogee]].<ref name=overview/> The average flight time is less than 30 minutes; usually between five and 20 minutes.<ref name=overview/> The rocket consumes its fuel on the [[First stage (rocketry)|first stage]] of the rising part of the flight, then often separates and falls away, leaving the payload to complete the arc, sometimes descending under a drag source such as a small balloon or a [[parachute]].<ref name=what/>

Sounding rockets have utilized balloons, airplanes and artillery as "first stages."

== Development history ==
{{Copy edit|date=October 2024}}
The earliest sounding rockets were [[liquid rocket propellant|liquid propellant]] rockets such as the [[WAC Corporal]], [[Aerobee]], and [[Viking (rocket)|Viking]]. The German [[V-2]] served both the US and the USSR's [[R-1 (missile)|R-1]] missile as sounding rockets during the immediate Post World War II periods. During the 1950s and later, inexpensive surplus military boosters such as those used by the [[MIM-3 Nike Ajax|Nike]], [[RIM-8 Talos|Talos]], [[RIM-2 Terrier|Terrier]], and [[AIM-7 Sparrow|Sparrow]] came to be used. Since the 1960s rockets specifically designed for the purpose such as the [[Black Brant (rocket)|Black Brant]] series have dominated sounding rockets, though often having additional stages, many from military surplus.

The earliest attempts at developing sounding rockets were in the Soviet Union. While all of the early rocket developers were concerned largely with developing the ability to launch rockets, some had the objective of investigating the stratosphere and beyond. The first All-Union Conference on the Study of Stratosphere was held in Leningrad (now St. Petersburg) in 1934.<ref>{{Cite news |last=Times |first=Walter Duranty special Cable To the New York |date=1934-03-31 |title=RUSSIANS TO PLAN ALTITUDE FLIGHTS; First All-Union Conference on Stratosphere Opens Today in Leningrad.

V. V. Razumov, of the Leningrad Group for the Study of Jet Propulsion, had a specific interest in sounding rocket design. As did A. I. Polyarny, who worked in a special group within the Society for Assistance to the Defense, Aviation and Chemical Construction of the U.S.S.R in Moscow, and designed the R-06 which eventually flew but not in the meteorological role.<ref name=Essayshr/>

The early Soviet efforts to develop a sounding rocket ultimately failed before WWII.<ref name=Essayshr/> P. I. Ivanov built a three-stage which flew in March 1946. At the end of summer 1946 development ended because it lacked sufficient thrust to loft a sufficient research payload.<ref name=Essayshr/>

The first successful sounding rocket was created at the [[California Institute of Technology]], where before [[World War II]] there was a group of rocket enthusiasts led by [[Frank Malina]], under the aegis of [[Theodore von Kármán]], known amidst the people of the CIT as the "Suicide Squad." Their immediate goal was to explore the upper atmosphere, which required developing the means of lofting instruments to high altitude and recovering the results. After the start of WWII the CIT rocketry enthusiasts found themselves involved in a number of defense programs, one of which was intended to produce a bombardment guided missile, the Corporal. Eventually known as the [[MGM-5 Corporal]] it became the first guided missile deployed by the US Army.

During WWII the [[Signal Corps (United States Army)|Signal Corps]] created a requirement for a sounding rocket to carry {{convert|25|lb}} of instruments to {{convert|100000|ft|km}} or higher.<ref>{{cite book |last=Bragg |first=James W. |title=Development of the Corporal: The Embryo of the Army Missile Program |volume=I |url=https://apps.dtic.mil/sti/tr/pdf/ADA586733.pdf |publisher=Reports and Historical Office, Army Ballistic Missile Agency, Army Ordnance Missile Command, Redstone Arsenal |location=Alabama |year=1961 |page=42}}</ref> To meet that goal Malina proposed a small [[Liquid-propellant rocket]] to provide the GALCIT team necessary experience to aid in developing the Corporal missile.<ref name="Malina3">{{cite book | last1 = Malina | first1 = F.

As the Signal Corps rocket was being developed for the Corporal project, and lacked any guidance mechanism, it was Without Attitude Control. Thus it was named the [[WAC Corporal]]. The WAC Corporal served as the foundation of Sounding Rocketry in the USA. WAC Corporal was developed in two versions, the second of which was much improved. After the war, the WAC Corporal was in competition for sounding mission funding with the much larger captured [[V-2 rocket]] being tested by the U.S. Army.  WAC Corporal was overshadowed at its job of cost-effectively lifting pounds of experiments to altitude, thus it effectively became obsolescent. WAC Corporals were later modified to become the upper stage of the first two staged rocket the [[RTV-G-4 Bumper]].

Captured V-2s dominated American sounding rockets and other rocketry developments during the late 1940s.<ref>{{cite book |last=DeVorkin |first=David H.  |title=Science With A Vengeance |publisher=[[Springer-Verlag]] |location=New York |year=1992 |isbn=0-387-94137-1}}</ref> To meet the need for replacement a new sounding rocket was developed by the [[Aerojet|Aerojet Corporation]] to meet a requirement of the [[Applied Physics Laboratory]] and the [[Naval Research Laboratory]].

The [[Viking (rocket)]] was intended from the start by the Navy not only to be a sounding rocket capable of replacing, even exceeding the V-2, but also to advance guided missile technology.<ref name=vikingstory>{{cite book|author=Milton W.

During the post WWII era the USSR also pursued V-2 base sounding rockets. The last two R-1As were flown in 1949 as sounding rockets. They were followed between July 1951 and June 1956 by 4 R-1B, 2 R-1V, 3 R-1D and 5 R-1Es, and 1 R-1E (A-1).<ref>{{cite web |url=http://www.astronautix.com/r/r-1.html |title=R-1 |last=Wade |first=Mark |date= |website=Astronautix |publisher=Mark Wade |access-date=26 September 2024 |quote=}}</ref> The improved V-2 descendant the R-2A could reach 120 miles and were flown between April 1957 and May 1962.<ref>{{cite web |url=http://www.astronautix.com/r/r-2a.html |title=R-2A |last=Wade |first=Mark |date= |website=Astronautix |publisher=Mark Wade |access-date=26 September 2024 |quote=}}</ref> Fifteen R-5Vs were flown from June 1965 to October 1983.

Other early users of sounding rockets were Britain, France and Japan.

Great Britain developed the [[Skylark (rocket)]] series and the later [[Skua]] for the [[International Geophysical Year]].<ref name=soundingrockets/>

France had begun the design of a [[Super V-2]] but that program had been abandoned in the late 1940s due to the inability of France to manufacture all components necessary. Though development of the [[Veronique (rocket)]] began in 1949, it was not until 1952 that the first full scale Veronique was launched. Veronique variants were flown until 1974.<ref name=soundingrockets/><ref>{{cite web |url=http://www.astronautix.com/v/veronique.html |title=Veronique |last=Wade |first=Mark |date= |website=Astronautix |publisher=Mark Wade |access-date=26 September 2024 |quote=}}</ref> The [[Monica (rocket)]] family, an all solid-fueled which was pursued in a number of versions and later replaced by the ONERA. series of rockets.<ref name=soundingrockets/>

Japan was another early user with the [[Kappa (rocket)]]. Japan also pursued Rockoons.<ref name=soundingrockets/>

The People's Republic of China was the last nation to launch a new liquid-fueled sounding rocket, the T-7.<ref>{{cite web |url=http://www.astronautix.com/t/t-7.html |title=T-7 |last=Wade |first=Mark |date= |website=Astronautix |publisher=Mark Wade |access-date=28 September 2024 |quote=}}</ref> It was first fired from a very primitive launch site, where the "command center" and borrowed power generator were in a grass hut separated from the launcher by a small river. There was no communications equipment- not even a telephone between the command post and the rocket launcher. The T-7 led to the T-7M, T-7A, T-7A-S, T-7A-S2 and T-7/GF-01A. The T-7/ GF-01A was used in 1969 to launch the FSW satellite technology development missions. Thus the I-7 led to the first Chinese satellite, the Dong Fang Hong 1 (The East is Red 1), launched by a DF-1. Vital to the development of Chinese rocketry and the Dong Feng-1 was [[Qian Xuesen]] (Tsien Hsue-shen in Wade Guiles transliteration) who with [[Theodore von Kármán]] and the California Institute of Technology "Suicide Squad" created the first successful sounding rocket the [[WAC Corporal]].

By the early 1960s the sounding rocket was considered established technology.

== Advantages ==
Sounding rockets are advantageous for some research because of their low cost (often using military surplus rocket motors<ref name="what" />),<ref name=overview/> relatively short [[lead time]] (sometimes less than six months)<ref name=what/> and their ability to conduct research in areas inaccessible to either balloons or satellites. They are also used as test beds for equipment that will be used in more expensive and risky [[orbital spaceflight]] missions.<ref name=overview/> The smaller size of a sounding rocket also makes launching from temporary sites possible, allowing [[Field research|field studies]] at remote locations, and even in the middle of the ocean, if fired from a ship.<ref>{{cite web|url=http://www.pha.jhu.edu/groups/rocket/general.html|title=General Description of Sounding Rockets|work=Johns Hopkins University Sounding Rocket Program|access-date=10 October 2006}}</ref>

==Applications==
===Meteorology===
{{further|Atmospheric sounding}}
[[File:Loki-dart display.jpg|right|thumb|A Loki-Dart (foreground) on display at the [[White Sands Missile Range]] [[rocket garden]]]]

[[Weather]] observations, up to an altitude of 75&nbsp;km, are done with '''rocketsondes''', a kind of sounding rocket for [[atmosphere|atmospheric]] observations that consists of a [[rocket]] and [[radiosonde]]. The sonde records data on [[temperature]], [[moisture]], [[wind speed]] and direction, [[wind shear]], [[atmospheric pressure]], and [[air density]] during the flight. [[Geographic coordinate system|Position]] data ([[altitude]] and [[latitude]]/[[longitude]]) may also be recorded.

Common meteorological rockets are the [[Loki (rocket)|Loki]] and [[Loki (rocket)|Super Loki]], typically 3.7 m tall and powered by a 10&nbsp;cm diameter [[Solid-fuel rocket|solid fuel rocket motor]]. The rocket motor separates at an altitude of 1500 m and the rest of the rocketsonde coasts to [[apogee]] (highest point). This can be set to an altitude of 20&nbsp;km to 113&nbsp;km.

===Research===
Sounding rockets are commonly used for:
* Research in [[aeronomy]], the study of the [[upper atmosphere]], which requires this tool for ''in situ'' measurements in the upper atmosphere.
*[[Ultraviolet astronomy|Ultraviolet]] and [[X-ray astronomy]], which require being above the bulk of the Earth's atmosphere.
*[[Microgravity]] research which benefits from a few minutes of [[weightlessness]] on rockets launched to altitudes of a few hundred kilometers.
*[[Remote sensing]] of Earth resources uses sounding rockets to get an essentially instant synoptic view of the geographical area under observation.<ref>{{Cite journal | doi=10.1080/07038992.1976.10854945| title=Remote Sensing of Earth Resources Sounding Rocket Capabilities| year=1976| last1=Payne| first1=B.R.| last2=Baird| first2=J.L.| journal=Canadian Journal of Remote Sensing| volume=2| pages=12–17| bibcode=1976CaJRS...2...12P}}</ref>

===Dual use===
Due to the high military relevance of ballistic missile technology, there has always been a close relationship between sounding rockets and military missiles. It is a typical [[dual-use technology]], which can be used for both civil and military purposes.<ref>DeVorkin, Science With A Vengeance, [[Springer-Verlag]], New York, 1992, ISBN 0-387-94137-1</ref> During the [[Cold War]], the Federal Republic of Germany cooperated on this topic with countries that had not signed the [[Non-Proliferation Treaty]] on Nuclear Weapons at that time, such as Brazil, Argentina and India. In the course of investigations by the [[peace movement#Germany|German peace movement]], this cooperation was revealed by a group of physicists in 1983.<ref name=NeS1983>{{cite journal | last = Campbell | author-link = Duncan Campbell (journalist, born 1952)| first = D. | date = 5 August 1983 | title = Germany helps Brazil to nuclear supremacy | journal = [[New Statesman]] | url= https://www.duncancampbell.org/menu/journalism/newstatesman/newstatesman-1983/germany%20helps%20brazil%20to%20nucular%20supremacy.pdf }}</ref> The international discussion that was thus set in motion led to the development of the [[Missile Technology Control Regime]] (MTCR) at the level of G7 states. Since then, lists of technological equipment whose export is subject to strict controls have been drawn up within the MTCR framework.
