Sterre en planete
from Sterre en Planete Hosted by RSG
Die span kyk na nuwe navorsing wat daarop dui dat die ruimte vinniger uitdy as wat aanvanklik verwag is. Dr Japie van Zyl gesels ook oor die groot aantal satelliete wat om die aarde wentel, en hoe daar bepaal word op watter hoogte sekere satelliete moet wentel. Dis ook belangrik om te weet of die satelliet 'n sirkelvormige of elliptiese baan moet hê.
