Mars’ Hebes Chasma

Perspective view of Hebes Chasma obtained by the High Resolution Stereo Camera (HRSC) on ESA’s Mars Express spacecraft.

Hebes Chasma is located at approximately 1° south and 282° east. The HRSC obtained image data on 16 September 2005 with a ground resolution of approximately 15 m/pixel.

The European Space Agency released beautiful photographs of the Hebes Chasma on Mars, taken by the Mars Express.

Latest data acquired by the OMEGA spectrometer on-board Mars Express has revealed water-bearing minerals such as gypsum in some areas of Hebes Chasma. This is proof that at least significant quantities of water once existed in Hebes Chasma.

What is a chasma? It’s a term in planetary geology for a “deep, elongated, steep-sided depression”, or a gigantic trough. This chasma is 5 miles deep.

The Daily Mail geeks out over the high resolution stereo camera, and shows a few more shots of the chasma. The ESA’s News article offers high-res photos for download and explains more about the chasma. Learn more about planetary geology (exogeology) at the USGS Astrogeology Research Program website.

These are the Best of Men

The Memphis Sanitation Worker Strike, 1968

These are the best of men, and I will not shrink this image to fit into my website.

Martin Luther King, Jr. died 40 years ago today as he helped black sanitation workers in Memphis strike for fair wages, fair working conditions, dignity and human rights. The signs reading “I am a Man” became an iconic symbol of the cause for which Dr. King and many others died.

The photograph above was taken by Ernest Withers, a civil rights photographer who passed away in 2007.

rootwork the rootsblog memorializes Ernest Withers:

legendary memphis photographer and
chronicler of the civil rights movement

irascible elder in his legendary kufi
everytime i see him he ask about my mama

they were about the same age same era,
racemen and racewomen from the oldschool

baba withers did a lot of legendary photos
but i think the one that mean the most to me

was one of the garbage workers strike in 68
my first real campaign in the struggle

my mama had me and my sisters out there on
picketlines, sitins and such since we was old enuf

to wear a sign

but it was the garbage workers strike and the
subsequent death of martin luther king that

turn me out
made me a conscious warrior

Sanitationstrikewhithersthe iconic sign of that struggle
was the garbagemens ‘i am a man’ picketsigns

and baba withers he got this shot of the garbage workers
with their i am a man signs straddling the street

move me to this day
