Is It a Correct Expression with Proper Logic?

"NASA's Mars Odyssey, also an orbiter, confirmed water ice at the north pole, along with dry ice ."
When I read this, I naturally thought that NASA has found ice water on Mars, because its Odyssey has "confirmed" that.
(But at the same time, I muttered to myself why rover Spirit has been managing to look for the trace of water on Mars)

Nevertheless, afterwards the writer said:"
Mars Express confirmed Odyssey's suspicions about the south pole."
OMG, what Odyssey found is just "suspicions"! So, why did the writer want to express the "suspicions" as "confirmed" thing?
I suspect the writer has used improper word.
What do you think about this?

(If the writer meant the suspicions were about the south pole, why does NASA want Spirit to look for the trace of water? It seems that doesn't hold water...)

Europe probe detects Mars water ice

CNN) -- The European orbiter Mars Express detected ice at the Red Planet's south pole, mission officials at Darmstadt, Germany, said Friday.

NASA's Mars Odyssey, also an orbiter, confirmed water ice at the north pole, along with dry ice -- frozen carbon dioxide -- in 2002. It picked up signs of hydrogen at the south pole, the first indication that water ice might be found there.

Mars Express confirmed Odyssey's suspicions about the south pole.

"We have already identified water vapor in the atmosphere," scientist Vittorio Formisano said. "We have identified water ice on the soil on the south polar caps."

Mars Express headed off for the fourth planet on June 2 specifically to look for water. It carried with it the European Space Agency's rover, Beagle 2, but that craft was never heard from after its expected Dec. 25 landing.

Express, however, attained its final operational orbit in the last week and has continued its scientific mission. Express made an unsuccessful attempt to contact Beagle 2 earlier this month when it passed near the rover's landing site.
