Al-Amal snaps first close-up images of Martian moon Deimos

During its first close fly-by of the Martian moon Deimos on March 10, 2023, the United Arab Emirates Mars orbiter Al-Amal (“Hope” in English) obtained the first close-up images of the moon.
The picture to the right show Deimos with Mars in the background. The full set of images, compiled into a movie, can be seen by clicking on the image.
The results were outlined by science lead Hessa Al Matroushi at a conference today.
During the 10 March fly-by, the mission team used all three onboard instruments to take readings spanning from the infrared to the extreme ultraviolet. The relatively flat spectrum the scientists saw is suggestive of the type of material seen on Mars’s surface, rather than the carbon-rich rock often found in asteroids, suggesting that Deimos was formed from the same material the planet. “If there were carbon or organics, we would see spikes in specific wavelengths,” she says.
These results probably put an end to the theory that Mars’ moons came from the asteroid belt. Instead, they either formed when the planet did, or were thrown free and settled into orbit after a very large impact, such as the ones that created either the Hellas or Argyre basins, both of which happened several billion years ago and thus provide ample time for the space environment to smooth the moon’s surface and add some craters.

Please consider supporting my work here at Behind the Black. Your support allows 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. 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. Only now does it appear that Washington might finally 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.

Winchell Chung likes this moon… a lot. He thinks this is *the* place to install a station, maybe buried in its regolith.
I almost completely agree. My only quibble is that I’d slow this sucker down so it’s permanently above some likely spot, and dangle a tether over that.
Great pic of it and Mars together. So how is Nyrath’s health holding up?
Looks like an embryo…
Is it possible Deimos has accumulated impact debris from Mars on its surface and that is masking the asteroid origin underneath?
