A color photo of John Glenn in the Friendship 7 capsule he used to orbit the Earth. He is wearing a spacesuit like the one worn by Shepard in the previous photo. A large, round helmet sports a translucent visor through which Glenn's brow, eyes, and nose are visible in profile. Several white tubes connect to the helmet. The suit itself is made of a silvery, reflective material. Glenn is strapped in with what appears to be a canvas harness. Numerous instruments are visible behind and around him.
A black and white photo of Katherine Johnson. She is wearing a top with thin stripes, a zipper down the front, and a pin on the collar. Johnson is looking directly at the camera and has a slight smile.

Today marks nine years since the Odessa massacre, when pro-Russian civilians were burnt alive by Ukrainian nationalists in the House of Trade Unions, Odessa.

The coverage of the massacre on WikiPedia is truly nauseating! Calling the slaughter of civilians by Azov and other neo-nazis for "2014 Odesa clashes"!

But hey, the world is black and white and this is the war between the good western friendly forces and evil Putin, don't you dare saying otherwise.
