== Introduction ==

'''Nasturtium officinale''', commonly known as watercress, is a fast-growing, aquatic or semi-aquatic perennial herb belonging to the Brassicaceae family. It is native to Eurasia but has been introduced and naturalized in many parts of the world, including North and South America, Australia, South Africa, and New Zealand<ref>https://nas.er.usgs.gov/queries/GreatLakes/FactSheet.aspx?Species_ID=229</ref><ref>http://misin.msu.edu/facts/detail?cname=Watercress&amp;id=235&amp;project=NA</ref><ref>https://fs.usda.gov/wildflowers/plant-of-the-week/nasturtium_officinale.shtml</ref>. Watercress is one of the oldest known leaf vegetables consumed by humans and is valued for its peppery flavor and nutritional content, including high levels of vitamins A and C, iron, calcium, and folic acid<ref>https://nas.er.usgs.gov/queries/FactSheet.aspx?SpeciesID=229</ref><ref>http://misin.msu.edu/facts/detail?cname=Watercress&amp;id=235&amp;project=NA</ref>. Its use extends beyond culinary purposes, as it has been employed in herbal remedies and is recognized for its potential health benefits, such as antioxidant properties and possible cancer-suppressing effects<ref>https://nas.er.usgs.gov/queries/GreatLakes/FactSheet.aspx?Species_ID=229</ref><ref>https://nas.er.usgs.gov/queries/FactSheet.aspx?SpeciesID=229</ref>.

== Characteristics ==

* '''Physical Characteristics''': Watercress has succulent, hollow stems that can grow up to 60 cm long. It has alternate, odd-pinnate leaves with 3 to 11 leaflets, which are ovate-lanceolate and often emarginate at the apex<ref>http://misin.msu.edu/facts/detail?cname=Watercress&amp;id=235&amp;project=NA</ref>. The plant produces white flowers in clusters, blooming from May to October<ref>http://misin.msu.edu/facts/detail?cname=Watercress&amp;id=235&amp;project=NA</ref><ref>https://fs.usda.gov/wildflowers/plant-of-the-week/nasturtium_officinale.shtml</ref>.
* '''Growing Conditions''': Watercress thrives in cold, alkaline waters of springs, streams, and similar aquatic environments. It prefers limy, sedimentary, or gravelly soils and can form large mats in slow-moving water bodies<ref>https://nas.er.usgs.gov/queries/GreatLakes/FactSheet.aspx?Species_ID=229</ref><ref>http://misin.msu.edu/facts/detail?cname=Watercress&amp;id=235&amp;project=NA</ref>.
* '''Lifecycle''': Watercress overwinters with terminal buds and is most abundant during summer and autumn. It reproduces both by seed and vegetatively, with plant fragments capable of giving rise to new plants<ref>https://nas.er.usgs.gov/queries/GreatLakes/FactSheet.aspx?Species_ID=229</ref><ref>https://nas.er.usgs.gov/queries/FactSheet.aspx?SpeciesID=229</ref>. The plant produces about 15 fruits per inflorescence, each containing 26 seeds<ref>https://nas.er.usgs.gov/queries/FactSheet.aspx?SpeciesID=229</ref>.

== Why is this crop useful for space? ==

Watercress could be beneficial for space cultivation due to several reasons: - '''Nutritional Value''': Its high content of essential vitamins and minerals makes it a valuable crop for maintaining health in space missions. - '''Ease of Growth''': As an aquatic plant, it can thrive in controlled aquatic environments, which might be feasible in space settings. - '''Phytoremediation Potential''': Watercress has been shown to accumulate contaminants like arsenic, nickel, and lead, making it a candidate for wastewater treatment or phytoremediation in space habitats<ref>https://nas.er.usgs.gov/queries/GreatLakes/FactSheet.aspx?Species_ID=229</ref>. - '''Compact Growth''': Its ability to grow in dense mats could be advantageous in space where space is limited.

== History of Cultivation in Space (if there is any) ==

There is no specific information available on the cultivation of watercress in space. However, its characteristics make it a potential candidate for future space agriculture projects, especially in controlled environment agriculture (CEA) systems. Such systems are being explored for their ability to support plant growth in space by providing controlled conditions for temperature, humidity, and light, which could be adapted for watercress cultivation.

While there are no documented experiments specifically on watercress in space, ongoing research into hydroponic and aeroponic systems for growing crops in space could potentially include watercress due to its adaptability to aquatic environments.
