Aparently planet venus(closest planet to earth), its slowing down. Or at least that is what the "venus expres"(last satellite sent to venus) its reporting to the scientifics of the NASA. Usually a day on venus, or a hole rotation over its own axis. takes about 243.0185 Earth days. but what the "the venus expres" measured was about 15 minutes longer than that. This is something that researchers and scientists have to pay atention to. Because if the planet rotation its accelerating, this means that future mission are not going to land where they are suppose to.
The phenomena its probably provocated by the fierce weather of venus, wich its probably causing friction on the planets rotation.
Other theory suggests that its because of some interactions in between the earth and venus gravitational interactions.
But it doesn't end here, the final theorysays that venus has always rotated like that and that the old measurements were from a time when venus rotate faster the usual.
This theory would match up with the long time measurement of venus rotation over the years.



A new rotational speed was discovered on venus, this probably means that the planet its slowing down but there are other ideas about it and the mos probable its that this its usual speed and the planet its just going back to it.
This would mean for the scientists to recalculate the landing places for future missions on venus, by about 20 kilometers away from were they were suppose to land
