habitable
a. 거주할 수 있는, 살기에 적합한

mass
n. 덩어리
A spacecraft is not going to be able to carry around masses of heavy, dirty stuff that can be used to grow plants in.
specifically
ad. 특별히, 특수하게
NASA has developed a special container called a Veggie, which is specifically designed for space-gardening on the ISS.
flourish
v. 잘 자라다, 성장하다

n. 농업
Experiments with plant production on the ISS have also proven valuable for agriculture on Earth, especially for areas in which water is scarce, soil is poor, or space is limited.
vertical
a. 수직의

Some of space trash float in space; much of it orbits Earth.
term
n. 용어
