Dawn Sets Course for Higher Orbit

Quote

After studying Ceres for more than eight months from its low-altitude science orbit, NASA's Dawn spacecraft will move higher up for different views of the dwarf planet.

Dawn has delivered a wealth of images and other data from its current perch at 240 miles (385 kilometers) above Ceres' surface, which is closer to the dwarf planet than the International Space Station is to Earth. Now, the mission team is pivoting to consider science questions that can be examined from higher up.

NASA Discovers "Lonely Mountain" on Ceres Likely a Salty-Mud Cryovolcano

Quote

An isolated mountain near the equator of the dwarf planet Ceres resembles a volcanic dome, according to new observations from NASA's Dawn mission. Like the "Lonely Mountain" Erebor in J.R.R. Tolkien's mythology, Ahuna Mons on Ceres was once occupied by a dragon, but one that "breathed" ice, not fire. The mountain likely formed as a salty-mud volcano. Instead of molten rock, salty-mud volcanoes, or "cryovolcanoes," release frigid, salty water sometimes mixed with mud.

"Ahuna Mons is evidence of an unusual type of volcanism, involving salty water and mud, at work on Ceres," said Ottaviano Ruesch of NASA's Goddard Space Flight Center, Greenbelt, Maryland and the Universities Space Research Association. "Geologic activity was discussed and debated among scientists: now we finally have observations testifying to its occurrence."

Ceres' Geological Activity, Ice Revealed in New Research

Quote

A lonely 3-mile-high (5-kilometer-high) mountain on Ceres is likely volcanic in origin, and the dwarf planet may have a weak, temporary atmosphere. These are just two of many new insights about Ceres from NASA's Dawn mission published this week in six papers in the journal Science.

"Dawn has revealed that Ceres is a diverse world that clearly had geological activity in its recent past,” said Chris Russell, principal investigator of the Dawn mission, based at the University of California, Los Angeles.

Very cool!

 

The writers of "The Expanse" can now justify themselves for having Ceres mined for ice to ship water to Earth and Mars.

Why is the hole next to the mountain about the same volume. I don't think it is what they say it is.

What do you think it is ?

Some kind of alien mining operation, probably old.

Yeah that is much more likely than a cryo volcano. :whistle:

I think I'll go with geological activity....:huh:
