Arugula vs. Rocket

By Jaxson

Main Difference

The main difference between Arugula and Rocket is that the Arugula is a edible annual plant, commonly known as salad rocket, rucola, rucoli, rugula, colewort, roquette and missile, spacecraft, aircraft or other vehicle that obtains thrust from a rocket engine.

  • Arugula

    Arugula or rocket (Eruca sativa; syns. E. vesicaria subsp. sativa (Miller) Thell., Brassica eruca L.) is an edible annual plant in the family Brassicaceae used as a leaf vegetable for its fresh peppery flavor. Other common names include garden rocket, (British, Australian, South African, Irish and New Zealand English), and eruca. Some additional names are “rocket salad”, “rucola”, “rucoli”, “rugula”, “colewort”, and “roquette”. Eruca sativa, which is widely popular as a salad vegetable, is a species of Eruca native to the Mediterranean region, from Morocco and Portugal in the west to Syria, Lebanon, and Turkey in the east.Eruca sativa grows 20–100 centimetres (8–39 in) in height. The pinnate leaves have four to ten small, deep, lateral lobes and a large terminal lobe. The flowers are 2–4 cm (0.8–1.6 in) in diameter, arranged in a corymb in typical Brassicaceae fashion, with creamy white petals veined in purple, and having yellow stamens; the sepals are shed soon after the flower opens. The fruit is a siliqua (pod) 12–35 millimetres (0.5–1.4 in) long with an apical beak, and containing several seeds (which are edible). The species has a chromosome number of 2n = 22.

  • Rocket

    A rocket (from Italian rocchetto “bobbin”) is a missile, spacecraft, aircraft or other vehicle that obtains thrust from a rocket engine. Rocket engine exhaust is formed entirely from propellant carried within the rocket before use. Rocket engines work by action and reaction and push rockets forward simply by expelling their exhaust in the opposite direction at high speed, and can therefore work in the vacuum of space.

    In fact, rockets work more efficiently in space than in an atmosphere. Multistage rockets are capable of attaining escape velocity from Earth and therefore can achieve unlimited maximum altitude. Compared with airbreathing engines, rockets are lightweight and powerful and capable of generating large accelerations. To control their flight, rockets rely on momentum, airfoils, auxiliary reaction engines, gimballed thrust, momentum wheels, deflection of the exhaust stream, propellant flow, spin, or gravity.

    Rockets for military and recreational uses date back to at least 13th-century China. Significant scientific, interplanetary and industrial use did not occur until the 20th century, when rocketry was the enabling technology for the Space Age, including setting foot on the Earth’s moon. Rockets are now used for fireworks, weaponry, ejection seats, launch vehicles for artificial satellites, human spaceflight, and space exploration.

    Chemical rockets are the most common type of high power rocket, typically creating a high speed exhaust by the combustion of fuel with an oxidizer. The stored propellant can be a simple pressurized gas or a single liquid fuel that disassociates in the presence of a catalyst (monopropellants), two liquids that spontaneously react on contact (hypergolic propellants), two liquids that must be ignited to react, a solid combination of fuel with oxidizer (solid fuel), or solid fuel with liquid oxidizer (hybrid propellant system). Chemical rockets store a large amount of energy in an easily released form, and can be very dangerous. However, careful design, testing, construction and use minimizes risks.
