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.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon. from any other book seller, or direct from my ebook publisher, ebookit.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

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?
