PHOENIX (AP) — Jodi Arias asked jurors Tuesday to give her life in prison, arguing she "lacked perspective" when she told a local reporter in an interview after she was convicted of murder that she preferred execution to spending the rest of her days in jail.

The only person responsible is the gunman, a union president says.

Authorities say they have enough evidence to justify seizing them by military force.

"K2 Tuesdays" is a series on the development of KySat-2, the latest spacecraft from Kentucky Space. Prior installments, new to old, are here, here, here, here, here, here, here, here, here, here, here, here, here, here and here. On Thursday May 16th the Kentucky Space and University of Kentucky teams went to Morehead State University to test the flight version of the power system developed for KySat-2. After an overview of the controlling software developed for the system, the team connected the UK-developed command and data handling system, or C&DH, to the MSU-developed electrical power system, or EPS, and all worked together as expected. We also connected the radio that will be used on K2 and transmitted data across the room. With three independent systems working together to transmit data, it was a big step forward in the design and development of KySat-2 The photos here show the work fitting actual components in the flight structure to determine the ideal wiring. As you can see we have moved from 3D printed fit checks to using the flight model chassis. More to come. Twyman Clements, Space Systems Engineer, Kentucky Space

Jack Fischer was one of four NASA astronauts to fly approach and landing simulations of Sierra Nevada Corporation's Dream Chaser spacecraft at the agency's Langley Research Center. The three-day simulations evaluated the spacecraft's subsonic handling in support of NASA Commercial Crew Program efforts.

Recent Sun Pillar seen near Toronto, Canada. Credit and copyright: Rick Ellis. Astrophotographer Rick Ellis from Toronto, Canada recently imaged a Sun pillar against a truly fiery sunset. Sun pillars are a vertical shaft of light extending upward or downward from the Sun, usually seen during sunrise or sunset. They form when when sunlight reflects off the surfaces of high-altitude hexagonal-shaped or flat ice crystals. The crystals are typically associated with thin, high-level clouds, such as cirrostratus clouds. “Fire and ice,” Rick said via email. “Robert Frost would approve.” Rick used a Canon A460, 1/100 seconds exposure at f/3.5, ISO 80. And here’s Robert Frost’s famous poem: (...)Read the rest of Astrophoto: Sun Pillar of Fire and Ice (101 words) © nancy for Universe Today, 2013. | Permalink | No comment | Post tags: Astrophotos, Sun Pillar Feed enhanced by Better Feed from Ozh

HARTFORD, Conn. (AP) — Toxicology tests on the body of the Newtown school shooter did not turn up any alcohol, illegal drugs or prescription medications, an official close to the investigation said Tuesday.
