Presented recently a unique simulation of a sunset on celestial bodies, the National Aeronautics and space administration (NASA) declared intention to uncover the mysteries of Triton, a moon of the planet Neptune.
About it writes National Geographic.
It is reported that when the spacecraft NASA “Voyager 2” flew past Triton three decades ago, many scientists there are many questions which yet remain unanswered.
In particular, the resulting images were visible massive dark jets of icy material emanating from the surface of Triton. At the same time, the landscape itself was young; again and again he was covered with fresh ice. For scientists it remains a mystery how the ancient moon, which is six times farther from the Sun than Jupiter, may still be active.
A new mission fighting for selection in the framework of NASA “Discovery” aimed to solve these puzzles.
The team under the name “Trident” was one of four developing concept studies for new missions. By the summer of 2021 will be selected for two of them, what would be the point of reference for the full mission.
The study of how newt has changed over time, would allow scientists to better understand how to develop and work bodies of the Solar system. Another issue is the retrograde motion of the moon Triton orbits in the opposite direction to the rotation of Neptune. It is the only moon in the Solar system.
In addition, the orbit of Triton is located in the extreme slope and offset at 23 degrees relative to the equator of Neptune. The researchers suggest that this celestial body had migrated from the Kuiper belt — a region consisting of material remaining after the formation of the Solar system.
The Triton is also unusual atmosphere filled with charged particle layer called ionosphere, is 10 times more active than the layer of any other moon in the Solar system. It is a strange feature since the Triton is 30 astronomical units from the Sun, hence in his case there must be some other source of energy.
“Triton has always been one of the most exciting and intriguing bodies of the Solar system. I always liked the image of Voyager and their tantalizing glimpses of this strange, mad moon, which nobody understands”, — was sure Louisa Procter, the head of the project “Trident”.
On the website NASA noted three main challengesthat need to be addressed for future missions.
It is believed that the plumes observed on the surface of Saturn’s moon Enceladus and Jupiter’s moon Europe, due to the fact that the water inside is pushed out through the thick icy crust. If the ocean is the source of the plumes on Triton, it will give scientists new information about how the oceans are formed internal of the celestial bodies. In contrast to other well-known ocean of the worlds, the potential of the ocean, Triton, likely appeared after he was captured by the gravity of Neptune.
It also would widen the understanding of scientists about where we can find water. Figuring out what factors lead to the fact that the body of the solar system has the necessary habitat ingredients, including water, is one of the three main goals of the “Trident”. On interplanetary spacecraft will be placed tool for investigating the magnetic field of the Triton, which will allow you to find out if under the surface of this moon of the ocean. Other instruments will explore the intense ionosphere, organic-rich atmosphere and quirky features of the surface.
The second objective is to study the extensive unexplored region on Triton, because the moon represents the greatest unexplored solid surface in the Solar system on this side of the Kuiper belt. A big part of what we know about the Triton, were derived from the “Voyager-2”, which photographed 40% of the surface of the satellite of Neptune.
The third main goal of the “Trident” is to understand how the mysterious surface of this moon continues to be updated. The answers can shed light on how landscapes develop on other icy bodies.
“As we said in our NASA proposal the mission, Triton is not just a key to the knowledge of the Solar system is a whole set of keys: an object captured from the Kuiper belt, a potential ocean world with active plumes, ionosphere and energetic young unique surface“, says Carl Mitchell, Trident, co-author of the project.
NASA wants to launch the mission in October 2025, during this time the Earth is aligned with Jupiter to create a window that appears only once in 13 years. This will allow the spacecraft to use the gravity of Jupiter to fly to Triton. In case of successful implementation of the project interplanetary spacecraft will reach Triton, in the year 2038.
Earlier, the “FACTS” wrote that NASA decided in deference to doctors on the cutting edge of the fight against the pandemic coronavirus to send to the Red planet, a special commemorative plaque.
