Measuring photometric brightness is a common tool for characterizaing satellites. However, characterizing satellite mega-constellations and their impact on astronomy research requires a new approach and methodology.

NASA is building optical communications technologies into its networks, using infrared laser links to offer missions higher data rates than comparable radio frequency systems.

Writing in his blog today, Sir Richard Branson announced plans to launch the world's largest ever satellite constellation.

NASA has issued a Request for Information (RFI) to investigate the possibility of using commercial Mars-orbiting satellites to provide telecommunications capabilities for future robotic missions to the Red Planet.

According to Euroconsult's new research report on High Throughput Satellites, 33 High Throughput Satellite (HTS) systems will be launched between 2014 and 2016, a record high compared to the total 31 HTS systems that were launched over the last decade. The growing popularity of HTS systems will bring the total cumulative investment to over $12 billion.

The National Aeronautics and Space Administration (NASA) is soliciting information through this Request for Information (RFI) in support of the Goddard Space Flight Center's (GSFC) Space-Based Relay Architecture Study.

NASA is releasing an open letter to the geosynchronous satellite community encouraging discussion on proposed "cooperative servicing aids," features that could be incorporated into new satellites to facilitate future on-orbit servicing.

Small GEO Satellite Platform Lands at ESA

After a careful four-day road trek from Switzerland, the first model of the Small GEO communications satellite platform has arrived at ESA for testing.

50th Anniversary of Telstar

Bell Labs, the research arm of Alcatel-Lucent (Euronext Paris and NYSE: ALU) will celebrate one of its great historical achievements with the 50th anniversary of the launch of Telstar I, the world's first active communications satellite. The launch on July 10, 1962, in partnership with NASA, ushered in the era of modern communications including real-time global telephone service, data communications and TV broadcasting.

SES TechCom, a subsidiary of SES S.A. (SESG.PA)(SESG.PA), announced today that it has signed contracts with Astrium and DLR at the German Space Operations Center in Oberpfaffenhofen to furnish important parts of the ground segment for the innovative European Data Relay System (EDRS).
