China cosecha el primer lote de ‘arroz espacial’

China cosechó su primer lote de arroz cultivado a partir de semillas que viajaron al espacio en la sonda lunar Chang’e-5 del país, dijeron funcionarios el domingo.

Cerca de 40 gramos de semillas hicieron el viaje a la luna en noviembre pasado. Algunas semillas pueden mutar y producir mayores rendimientos cuando se plantan en la Tierra después de haber sido expuestas a radiación cósmica y gravedad cero.

Los chinos han estado enviando semillas al espacio desde 1987, incluidos arroz, algodón y tomates.

Los medios estatales chinos informaron que se necesitaron cuatro meses de cultivo en la Universidad Agrícola del Sur de China en la provincia de Guangdong antes de que las semillas comenzaran a producir granos.

«Tomará algunas generaciones más y pasará por una serie de pruebas, comparaciones y ensayos regionales antes de aprobar revisiones a nivel provincial y estatal», dijo al Global Times Xu Lei, un experto en cultivo de arroz de la provincia de Liaoning, en el noreste de China.

Wang Ya’nan, analista espacial y editor en jefe de la revista Aerospace Knowledge con sede en Beijing, dijo que cree que hacer crecer los lotes es el primer paso para producir alimentos en el espacio.

«Con estancias humanas a largo plazo en la estación espacial, los investigadores esperan realizar experimentos para probar un ecosistema de auto-reciclaje en el espacio, lo que reducirá en gran medida los costos y reducirá los recursos necesarios para futuros vuelos espaciales tripulados», dijo Wang al Global Times. «Esto apoyará más exploraciones en el espacio profundo, incluida la construcción de una base de investigación lunar y misiones tripuladas a Marte».UPI
