NASA is hard at work developing what they believe is the best space engine for future missions to Mars and beyond. It’s not warp drive. No, nothing so exotic or dreamy. In fact, it already exists. The challenge is to enhance it for our needs in space in the coming decades. That is the hope, and the goal, of NASA’s continuing development of solar electric propulsion (SEP).

Solar electric propulsion uses electricity generated from solar arrays to ionize atoms of the propellant xenon. These ions are then expelled by a strong electric field out the back of the spacecraft, producing thrust. So, in short, SEP is a propulsion system that is a combination, or coupling, of solar array technology and ion thruster technology.

The NASA Glenn Research Center in Cleveland, Ohio, has been a leader in both ends of this technology for decades. Its work with ion thruster technology began with the Space Electric Rocket Test 1 in 1964. Today, ion thrusters are used to keep over 100 geosynchronous Earth orbit satellites in their locations, a process called station keeping. The Deep Space 1 mission, which made flybys of asteroid Braille and the comet Borelly between 1998 and 2001, used the NASA Solar Technology Application Readiness (NSTAR) ion propulsion system.

He sat at his desk, woozy. He tried to move, his arms unresponsive. He searched for help, moving into the aisle in his swivel chair only to find all his coworkers had abandoned him. Was he being drugged? If so, it was the simplest scene he could imagine.Whoever was trying this was extremely stupid or extremely powerful. He'd find out soon enough.

Call for abstracts for "Images of Blackness in Graphic Novels"

CFP: Images of Blackness in Graphic Novels, Past and Future (Extension to 3/31/18)

by Brian Yates

This edited volume will offer an opportunity for authors to investigate the ways in which blackness is reimagined in both mainstream and independent comics. Specifically, I propose responding to the following questions: What are the ways in which heroism is redefined by black characters? How are black futures reimagined? What gendered arguments are made through this medium? What are the challenges in presenting to black audiences in this largely white genre? How do the creators depict the continent of Africa and/or communities in the African Diaspora? How are black bodies presented in graphic comics and novels? Finally, how are themes of social justice specific to black communities presented in this…

SKYCITY TALKRADIO

THE UNDERGROUND BY ROXANNE BLAND

Life as alpha of a werewolf pack is anything but predictable. But even Parker Berenson is surprised by the latest twist: he’s fallen in love with a space alien. Problem is, he suspects Melera, his sexy new flame, might be the serial killer terrorizing Seattle. Or maybe she isn’t. After all, just because she’s an interstellar assassin doesn’t mean she’s guilty.
