Arugula

Introduction

Eruca sativa, commonly known as arugula, is a member of the Brassicaceae family, which includes other cruciferous vegetables like broccoli and cabbage. Although it is sometimes referred to as Eruca vesicaria or E. vesicaria subsp. sativa, Eruca sativa is a widely recognized name for this plant^[1]^[2]. Arugula is native to the Mediterranean region and has been cultivated since Roman times for its peppery, nutritious leaves^[3]^[4]. It is valued for its rich content of vitamins, minerals, and antioxidants, making it a popular ingredient in salads and other dishes^[5]^[6].

Characteristics

Physical Characteristics: Arugula is an annual plant that grows up to 20 to 100 cm in height. Its leaves are deeply lobed, resembling those of dark green oak leaf lettuce, and can be harvested in as little as 20 days after sowing^[7]^[8]. The plant produces creamy white flowers with purple veins, which are edible and used as a garnish^[9].
Growing Conditions: Arugula prefers full sun and well-drained soil. It is a cool-season crop, tolerating light frost, and can be grown in containers or directly in the ground^[10]. Successive plantings every 2-3 weeks ensure a continuous supply of fresh leaves^[11].
Lifecycle: Arugula grows quickly from seed, maturing in about 40 to 50 days under optimal conditions. It can bolt (go to seed) if exposed to high temperatures or long days, but this can be managed by providing light shade during hot weather^[12].

Why is this crop useful for space?

Arugula is a promising crop for space cultivation due to several factors: - Nutritional Value: It is rich in vitamins A, C, and K, as well as minerals like calcium and iron, making it an excellent choice for maintaining nutritional health in space missions^[13]. - Growth Characteristics: As a fast-growing crop, arugula can provide a quick source of fresh produce in controlled environments like hydroponics or aeroponics, which are often used in space agriculture^[14]. - Low Resource Requirements: Arugula requires minimal space and can thrive in a variety of lighting conditions, making it suitable for compact growing systems in space^[15].

History of Cultivation in Space (if there is any)

While there are no specific records of Eruca sativa being cultivated in space, there have been experiments with other Brassicaceae family members, such as lettuce and radishes, in space environments. For example, NASA’s Veggie experiment on the International Space Station has successfully grown lettuce and other leafy greens using hydroponic systems^[16]. These experiments demonstrate the feasibility of growing similar crops like arugula in space, but specific trials for arugula have not been documented.
