PARIS — Delays in the launch of three telecommunications satellites atop European, Russian and U.S. rockets will reduce projected 2013 earnings for Luxembourg-based SES, the world’s second-largest fleet operator by revenue.

NASA is revealing its most detailed assessment yet of the design challenges that are being tackled as part of its plan to develop and test the heavy-lift Space Launch System (SLS) vehicle for human exploration from 2017 and beyond.

NEW DELHI — The launch of India’s GSAT-14 satellite aboard a Geosynchronous Satellite Launch Vehicle (GSLV-D5) fitted with an indigenous cryogenic engine will take place on Aug. 19, a top scientist says.

Russia’s Progress 50 cargo capsule departed the International Space Station’s (ISS) Russian segment on July 25, opening a berthing port for the July 27 arrival of a replacement freighter carrying a NASA space suit repair kit among its nearly 3 tons of supplies.

DENVER — Dextre, the multipurpose dexterous manipulator that rides at the end of the International Space Station’s robotic arm, will acquire some new tools and tasks by year’s end. Among the cargo tucked into Japan’s fourth H-II Transfer Vehicle scheduled for launch to the ISS on Aug. 4 is Phase II hardware for NASA’s Robotic Refueling Mission (RRM), a testbed the size of a window air conditioner bolted onto the station truss that mimics operational satellites.

NASA will expand its probe into the water leak that prompted an abrupt end to a July 16 spacewalk outside the International Space Station with the creation of a five-member mishap investigation board.

FIZZY COMET: Observations using NASA’s Spitzer space telescope have revealed what most likely are strong carbon dioxide emissions from Comet ISON ahead of its anticipated pass through the inner solar system later this year, the agency announced. Images captured last month with Spitzer’s Infrared Array Camera indicate carbon dioxide is “fizzing” away from what has now been dubbed the “soda-pop comet,” along with dust, forming a tail 186,400 mi. long. Scientists estimate the comet is emitting about 2.2 million lb. [1 million kg] of gas and about 120 million lb.
