Greater Moon has mysterious oscillations in the atmosphere with the change of Saturn stations

Researchers at the University of Bristol in the United Kingdom, who tracked the climate of Titan and the process of changes over time. Data from 13 years of observations of the thermal infrared of Cassini Mission and The results of this research were published in Planetary Science Journal.

According to partnership data, the dense and nebula atmosphere of Titan does not turn to its surface, but the gyroscope makes it oscillation, which turns out to be a year of seasons. The only moon and NASA Tita with a significant atmosphere in the solar system of Saturn, the helicopter, is preparing a mission to study with drone, similar to dragonfly, which reaches the destination in 2030.

“The behavior of Titan’s atmosphere is so strange” at the Earth Sciences School of Bristol, said Lucy Right, Lucy Right Communication. The atmosphere of Titan acts as a gyroscope, stabilizing in space.

“We believe that some incident in the past is diverting the atmosphere of its rotation axis and causing its oscillation. We have found that the size of this slope is turned with Titan stations,” Lucy Right said.

The group studied the symmetry of the Titan atmospheric temperature field and found that it was not properly concentrated at the pole as expected. Instead, it changes over time to suit the long seasonal cycle of Titan. Notice that in the Titan is about 30 years on Earth every year.

Bristol’s co -writer and asteroid professor Nick Teenbi also “stressed” Instead of influencing by the sun or Saturn, the direction of arch is stable in space“.” That gives us clues about the cause. However, we have a new mystery in hand, ”he said.

The invention now published on NASA’s next dragonfly mission, which reached Titan in 2030. As the Daganfly goes into the atmosphere, it is driven by the fastest winds of Titan — 20 times faster than surface rotation.

It is important to understand how the climate is asons to calculate the dragonfly’s milestone trajectory. Researchers suggest that the tilt affects the process of transported by load air, so this research can help engineers to predict where it is.
