HOUSTON — Investigators assisted by astronauts aboard the International Space Station (ISS) are entering the next phase of troubleshooting of the July 16 spacesuit water leak that brought all NASA-sponsored spacewalks outside the six-person orbiting science laboratory to a halt.

MOBILE SATELLITE: The active Mobile Satellite Service (MSS) terminal base grew at a compound annual rate of 10% over the past five years, with more than 2.9 million active MSS terminals deployed on a global basis in 2012, according to Euroconsult. Revenues generated by the six active MSS operators reached $1.5 billion. “The industry remains very concentrated with the leading three operators, Inmarsat, Iridium and Thuraya still accounting for close to 90% and Inmarsat alone having a market share of 55%,” Euroconsult says.

Gregory Johnson, the former NASA astronaut and retired U.S. Air Force colonel, will become executive director of the Center for the Advancement of Science in Space (Casis), the Florida-based nonprofit selected two years ago by the space agency to manage research across the U.S. National Laboratory elements of the International Space Station (ISS). The appointment is effective Sept. 1, according to an Aug. 26 Casis announcement.
