Microgreens have gained immense popularity in recent years due to their high nutritional value, diverse flavours and adaptability to small-scale and urban farming. These tender greens, larger than sprouts but smaller than baby vegetables or greens, are packed with densely concentrated nutrients and health-promoting compounds. The aim of the paper is to cultivate, nutrition, journey to space and market trends of microgreens. They are favoured by high-end chefs and health-conscious consumers as garnishing elements in salads, soups, and sandwiches. Vegans also appreciate microgreens for their nutrient-enriched dietary value. Cultivating microgreens is feasible in small spaces, making them a viable option for urban farming. Various substrates, such as soilless, aeroponics, hydroponics, and aquaponics, are being explored for their cultivation. Microgreens are not only rich in ascorbic acid, vitamins, and micro and macro elements, but they also show promise for space exploration. Their unique properties and compact growth make them an alternative food source for astronauts. Additionally, the market for microgreens is booming, with India and North America showing promising growth. The global microgreens market is projected to reach a value of USD 2.6 billion by 2031, fueled by the increasing demand and versatile cultivation methods. With their exceptional nutritional profile and versatile cultivation options, microgreens are an attractive option for both consumers and growers, offering a bright future ahead. This review has provided a comprehensive overview of microgreens, from their historical significance to their cultivation methods, nutritional values, and potential applications in space exploration.
