SPACE STATION CREW MOVED AFTER GAS LEAK FEARS - Crew members were evacuated from a US segment of the International Space Station after an ammonia leak was suspected. But Nasa officials now says a sensor problem probably created the false impression of leaking coolant. The Russian space agency emphasised that the crew members had not been in any danger. It said that mission control experts in Russia and the US had quickly co-operated to ensure the crew's safety. The six crew members on the outpost put on breathing equipment and moved into the Russian segment after the alert at around 0900 GMT, closing the hatch to the US side behind them.

NAVY'S NEW 'BEACH BALL' SATELLITE TAKES A SPIN FROM THE ISS - Astronauts aboard the International Space Station have launched a spherical, beach ball-sized satellite whose performance could help the military in its quest for smaller, less expensive satellites that can be used to extend communications or support specific missions. Developed by the Naval Research Lab, the SpinSat’s primary mission is to test a new thruster technology that could be applied to altitude control for small satellites the Navy is developing, such as cube, pico and nano staellites.

VIASAT SELECTS SPACEX TO LAUNCH VIASAT-2 SATELLITE - ViaSat Inc. is taking another step forward in the transformation of satellite broadband with the selection of SpaceX to launch ViaSat-2, the next generation of high-capacity broadband satellite. ViaSat-2 is scheduled for a late summer 2016 launch aboard a SpaceX Falcon Heavy from the Kennedy Space Center in Florida. Falcon Heavy is the world's most powerful rocket, with the ability to lift more than twice the payload of the next closest launch vehicle at only one-third the cost. Falcon Heavy is an evolution of the flight-proven Falcon 9 that is used to launch commercial satellites as well as cargo missions to the International Space Station.

LAUNCH OF RUSSIAN PROTON CARRIER ROCKET WITH BRITISH SATELLITE SET FOR JANUARY 30 - The launch of a Russian Proton-M carrier rocket with British communications satellite Inmarsat-5F2 has been scheduled for January 30 from the Baikonur space center that Russia leases from Kazakhstan, Russian Federal Space Agency Roscosmos told TASS Monday. “The Inmarsat-5F2 spacecraft was delivered to Baikonur on December 18. Specialists of the Boeing manufacturer company’s space programs unit immediately started preparing and checking it in the integration and test building,” Roscosmos said.

FOURTH NAVIGATION SATELLITE LAUNCH IN MARCH - The fourth navigation satellite of the country is getting ready for launch in March, and it will be another step forward for India in evolving its own navigation satellite system and not depend on the Geographical Positioning System (GPS) service of the U.S. Cryogenic propulsion systems on board PSLV-C27 rocket that will launch the satellite are being developed by scientists of the ISRO Propulsion Complex at Mahendragiri in Tirunelveli district. S. Ingersol, group director of the complex, told The Hindu, “Totally, seven satellites are required to be launched to complete the configuration under the Indian Regional Navigation Satellite System (IRNSS) and already three had been launched.

HUNGARY’S FIRST SATELLITE DEORBITS AFTER COMPLETING MISSION - Having successfully completed its mission, Masat-1, Hungary’s first satellite, is now destroyed after entering the Earth’s atmosphere, the research team controlling its mission told the Hungarian news agency MTI on Saturday. The satellite is believed to have burned up as projected, between 23:15 pm on Friday and 0:45 am on Saturday. According to the scientists, its last online package was received at 21:21.43 pm on Saturday, after which no further signal from Masat-1 was detected. This is due partly to the fact that the satellite spent its final hours above an ocean or an area where no surface radars collecting data for Hungarian controllers exist.

DRAGON SUCCESSFULLY LAUNCHED, ROCKET RECOVERY DEMO CRASH LANDS - A commercial Dragon spaceship soared into orbit from Cape Canaveral on Saturday in pursuit of the International Space Station, but the automated craft’s Falcon 9 booster crash landed after flying back to Earth in a daring test of future reusable rocket technologies. SpaceX founder Elon Musk tweeted updates on the daring flyback maneuver, saying the 15-story booster made a hard landing on a vessel positioned 200 miles northeast of Cape Canaveral. Details on what happened during the rocket’s landing were not immediately known. More (Source: SpaceFlight Now - Jan 11)
BLOCK II GPS SATELLITE RETIRES AFTER 22 YEARS - Jan. 6 was the last day of service for GPS satellite SVN-26. SVN-26 was a Boeing/Rockwell International Block II GPS satellite launched July 7, 1992. It was one of the first generation of operational GPS satellites, and had a design life of only 7.5 years. On Jan. 7, SVN-26 (PRN-26) was transferred from the operational ground control system (AEP) to Launch, Anomaly and Disposal Operations (LADO). CGSIC Executive Secretariat Rick Hamilton, USCG Navigation Center, remarked on its longevity. “A testament to the satellite engineers and the men and women of the Air Force, the Second Space Operations Squadron at Schriever Air Force Base has successfully managed SVN-26 in its mission for over 22 years.” More (Source: GPSworld.com - Jan 10)
NEW MISSION: DSCOVR SATELLITE WILL MONITOR THE SOLAR WIND - Solar wind – that is, the stream of charged electrons and protons that are released from the upper atmosphere of the Sun – is a constant in our Solar System and generally not a concern for us Earthlings. However, on occasion a solar wind shock wave or Coronal Mass Ejection can occur, disrupting satellites, electronics systems, and even sending harmful radiation to the surface. Little wonder then why NASA and the National Oceanic and Atmospheric Administration (NOAA) have made a point of keeping satellites in orbit that can maintain real-time monitoring capabilities. The newest mission, the Deep Space Climate Observatory (DSCOVR) is expected to launch later this month. More (Source: Universe Today - Jan 10)
