Sunday 12 April
I was lucky enugh t be chsen as a visitr t the space statin! After an exciting blast int rbit, I culdn’t wait t lk thrugh the space statin windws int deep space! Yu can imagine my disappintment when I didn’t see many stars. The astrnauts laughed and explained t me that we were still in the sunlight, s f curse we culdn’t see much, because the light was t bright.
Shrtly after, we passed int Earth’s windw, and I lked ut f the windw t see the mst amazing number f stars! I felt very excited! This is the mst unfrgettable experience n the statin. Sn after that, it was time fr dinner. The thing I nticed mst was nt the zer gravity measures fr eating, but the fact that the fd didn’t have much taste. And my nse felt blcked. It turns ut these things are related, because in zer gravity, yur face swells up mre. After that, it was time t get strapped int bed. It was a bit hard t sleep in zer gravity--my arms kept flating away, and I wke up t see them right in frnt f my face, instead f lying n the bed like they wuld n Earth.
Despite even simple things being harder t d, I really enjyed being in zer gravity, and I lved being able t flat arund instead f having t walk. It’s a pity my stay n the statin was s shrt. It wuld have been great t stay lnger and learn mre abut life in space!
