Space X Ready for Orbit
Space pioneer Elon Musk hopes to put his name in the history books once again next week, with the planned launch and recovery of the first commercially-operated spacecraft from orbit.
In June, SpaceX, as the company is known, launched its 18-story Falcon 9 rocket and successfully flew it for more than nine minutes. It was the first privately funded U.S. rocket launch in decades. However, this week's scheduled mission to launch and return an unmanned, reusable Dragon capsule from low-earth orbit, anticipated to last for hours, poses many more challenges. Placing the vehicle into a such an orbit at speeds exceeding 17,000 miles per hour, then maneuvering through a fiery reentry and splashdown in the Pacific Ocean will require a flawless trajectory, a reliable heat shield and finally, perfect operation of the redundant parachutes, according to space experts.

For Damien Echols, tattoos are part of his existential armor.
- In prison Damien Echols was known by his number SK931, not his name, and had his hair sheared off. Stripped of his identity, the only thing he had left was his skin.
- This is why he began tattooing things that are meaningful to him — to carry a "suit of armor" made up the images of the people and objects that have significance to him, from his friends to talismans.
- Echols believes that all places are imbued with divinity: "If you interact with New York City as if there's an intelligence behind... then it will behave towards you the same way."
