Pioneer cover

From the press release: From the moment he is handed a possibility of making the first alien contact, Saunders Maxwell decides he will do it, even if doing so takes him through hell and back.

 
Unfortunately, that is exactly where that journey takes him.

 
The vision that Zimmerman paints of vibrant human colonies on the Moon, Mars, the asteroids, and beyond, indomitably fighting the harsh lifeless environment of space to build new societies, captures perfectly the emerging space race we see today.


He also captures in Pioneer the heart of the human spirit, willing to push forward no matter the odds, no matter the cost. It is that spirit that will make the exploration of the heavens possible, forever, into the never-ending future.

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.

    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!
