Today’s CSExtra offers the latest reporting and commentary on space related activities from across the globe. NASA readies Launch Pad 39B at the Kennedy Space Center for the Space Launch System heavy lift rocket, with its first test launch anticipated for the last half of 2018. NASA’s New Horizons mission team will get a chance at a second flyby target after speeding past Pluto in July. The source of the 2013 Chelyabinsk fireball was a well battered fragment from a main belt asteroid, say scientists. NASA’s Mercury orbiting MESSENGER spacecraft lowers its altitude for the long running mission’s final weeks. Aging meteorite produces odd “quisicrystal.”  NASA astronaut Scott Kelly, who is set to begin the first U.S. one-year mission in space this Friday, will be a subject of genetics experiment with his identical twin brother Mark Kelly, a retired NASA astronaut. International Space Station astronauts capture photos of rare solar eclipse. Space Station commander Terry Virts is a big Baltimore Orioles fan.  U.S., United Arab Emirates agree to cooperate in space. Sierra Nevada leverages work on Dream Chaser for possible International Space Station re-supply missions. Russians sack second Vostochny Cosmodrome construction chief. A look at major space policy related activities planned for the week ahead.
