Humans have been living and working onthe space station for 20 years. Most of their mealsare prepackaged， though sometimes astronautsreceive fresh treats from resupply missions. Thelonger that packaged food is stored， the more itloses nutrients like vitamin C and vitamin K.

Astronauts have successfully grown 10different crops on the space station since 2015 and had the chance to sample each one. TheInternational Space Station hosted a taco party for astronauts on Friday as they celebratedthe harvest of the first chile peppers grown in space. The crew finally had a chance to tastethe peppers after initially kicking off the plant experiment on the space station in July.

Plant Habitat?04 is one of the most complex plant experiments on the orbiting laboratoryto date because peppers take much longer to grow than the previous experiments，which included various types of lettuce， flowering zinnias （百日菊） and even radishes（蘿卜）.

After growing for four months， the peppers were harvested on Friday by NASA astronautMark Vande Hei. Next， they were cleaned before the crew settled in to taste some ofthe red and green chiles and take surveys about the flavor and texture.

Forty?eight pepper seeds launched in a carrier on a resupply mission to the space stationin June. The carrier was placed inside the labs Advanced Plant Habitat， which isabout the size of a microwave. The habitat can be monitored and controlled from KennedySpace Center in Florida， including watering， lighting and turning on fans to promote pollen（花粉） transfer.
