Inyanga enyuka ngasenyakatho futhi ihamba kancane idlula ku-Mars.
I-Phobos iyinyanga encane, engajwayelekile engaphezu kuka-22 km ububanzi. Ijikeleza iMars ngaphezu kwehora 8, ngokushesha kunaleyo i-Mars ejikelezayo, ngakho ikhula emazantsi futhi ihlala emaphakathi njengoba kuboniswe yi-Mars.
Izinto ezihambayo ziyisusa kancane kancane ifike eduze kweMars. Ezinye izikhulu zezinkulungwane zeminyaka izobe ihlaselwa yiMars noma ihlukaniswe ibe yi-ring.

Amathuluzi nama-lessons asebenzisa amamodeli alula ukufundela kuphela. Akufanele asetshenziswa ukuhlola, ukuhlela umsebenzi noma noma yiluphi ukhetho lokusebenzela. Izitifiketi zimahhala futhi aziqinisekisiwe. Funda isichazamazwi sezinto ezifundiswayo
