Chèchè yo te long ki te fèt ke dlo likid se yon engredyan prensipal pou lavi - maître NASA an nan demand lan se "swiv dlo a" - men syantis yo kounye a fè fas a yon dilèm sou ki jan li mennen envestigasyon larivyè yo. Rover a Kiryozite ki te eksplore Mas pou twa ane se pa esteril, ak te kapab kontamine zòn ki mouye ak pinèz terrestres ki kole sou veso espasyèl la nan Cosmos yo. Rover a te kapab mennen ankèt sou nan yon distans, ak yon lazè ki ta mezire tach yo, oswa li te kapab riske apwoche nan efè moute kèk labou.

Researchers have long held that liquid water is a primary ingredient for life – Nasa’s mantra in the quest is “follow the water” – but the scientists now face a dilemma over how to investigate the streams. The Curiosity rover that has explored Mars for three years is not sterile, and could contaminate the wet areas with terrestrial bugs that clung onto the spacecraft through the cosmos. The rover could investigate from a distance, with a laser that would measure the streaks, or it could risk approaching to scoop up some mud.
