That close to its sun the planet is probably tidally locked and thus not rotating. If there were water on the planet (which is not known), and if it has an atmosphere (which is not known), and if solar flares have not destroy the atmosphere and water on the planet (which is not known), the frigid temperatures on the back side of the planet would have frozen out the water long ago.
But, hey, if this news story can win some more funding for France’s CNRS research institute, that’s what counts.
It was tidally locked. That is the first thing we fixed. It was the only way we could even consider making it a way-point for our crews headed to Earth and Titan.
