New data: The asteroid Psyche is rusting
Using new ultraviolet data from the Hubble Space Telescope, astronomers now believe that the high density asteroid Psyche, thought to be largely metallic, is rusting because of interaction with the solar wind.
Becker observed the asteroid at two specific points in its rotation to view both sides of Psyche completely and delineate as much as possible from observing the surface at ultraviolet (UV) wavelengths.
“We were able to identify for the first time on any asteroid what we think are iron oxide ultraviolet absorption bands,” she said. “This is an indication that oxidation is happening on the asteroid, which could be a result of the solar wind hitting the surface.”
There will be a U.S. probe to Psyche launched in ’22.
The support of my readers through the years has given me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Four years ago, just before the 2020 election I wrote that Joe Biden's mental health was suspect. Only in this year has the propaganda mainstream media decided to recognize that basic fact.
Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Even today NASA and Congress refuse to recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.

For rust (iron oxide) to form, there must be a source of oxygen. Have they done the mass balance calculation?
For iron oxides see “Swaddle TW, Oltmann P (1980) Kinetics of the magnetite-maghemite-hematite transformation, with special reference to hydrothermal systems. Can J Chem 17(58):1763–1772”
Asteroid is rusting?
Must be the extra moisture because of Global Climate Warm-freezing Change.

Phill O noted: “For rust (iron oxide) to form, there must be a source of oxygen.”
An early job in my career was at a laboratory that built mass spectrometers to measure the content of the solar wind. One thing that they found was a surprising amount of oxygen ions in the solar wind. Another possible source could be water that may outgas from within the asteroid.
Edward, the article by Swaddle indicated the need for water for certain iron oxides (which had been identified at that time) to form. We did not consider oxygen from the solar wind, in that article.
Thanks!
