NASA tests CubeSat-based laser communications

NASA has teamed up with The Aerospace Corporation of El Segundo to test a new CubeSat-mounted laser communication system. While the mission, known as the Optical Communications and Sensor Demonstration (OCSD), has already been successfully placed in orbit, the team is currently working to resolve an issues with its attitude control system.Read More

Samsung's giant satellite network could enable high-speed internet access across the globe

A highly ambitious proposal recently advanced by Samsung describes the deployment of a huge network of 4,600 near-Earth satellites that would provide internet coverage on a truly global scale. The artificial constellation would more than double the number of working satellites in orbit around our planet and lead to low-latency and (potentially) low-cost access to about 200 GB of internet traffic a month for up to five billion people, no matter their location.Read More

NASA teleconference on sea level change warns of rising oceans

On Aug. 26, NASA held a media teleconference regarding current predictions on sea level rise, highlighting the risks to coastal populations in low-lying areas, and the inherent problems in creating reliable global models. A panel of experts from NASA's recently-founded Sea Level Change Team tells us that ocean levels are inexorably on the rise, but gaps in our understanding and ability to survey risk regions mean we don't know just how fast the change will take place.Read More

Lockheed Martin's satellite cooler gets triple the power

Space is cold, but not cold enough for satellite sensors that need to be kept at cryogenic temperatures. Lockheed Martin’s lightweight High Power Microcryocooler is designed to keep these vital components cold, and it now packs three times the power density of previous systems.Read More

Construction of next-gen hurricane-hunting satellites begins

What is small enough to fit in an airliner carry-on bin and has the potential to save thousands of lives and millions of dollars worth of property? The answer is the Cyclone Global Navigation Satellite System (CYGNSS) – NASA’s next-generation hurricane-observing microsatellites, which are now being assembled at the Southwest Research Institute (SwRI) in San Antonio, Texas.Read More

Scramjet-based project looks to blast Australia into space

The list of spacefaring nations remains small, but thanks to continuing advances in technology that promise to reduce the financial and logistical hurdles involved, the numbers are set to increase. One country that could be joining the club, if the University of Queensland (UQ) and Heliaq Advanced Engineering get their way, is Australia. The two are teaming up on a project intended to deliver payloads weighing from 50 to 500 kg (110 to 1,102 lb) into orbit.Read More
