Small Satellite Deployed From the Space Station

A satellite is ejected from the Japan Aerospace Exploration Agency (JAXA) Small Satellite Orbital Deployer on the International Space Station on Dec. 19, 2016. The satellite is actually two small satellites that, once at a safe distance from the station, separated from each other, but were still connected by a 100-meter-long Kevlar tether. via NASA http://ift.tt/2hU5LNj

View of NASA’s CYGNSS Hurricane Mission Launch From Chase Plane

Hurricane forecasters will soon have a new tool to better understand and forecast storm intensity. A constellation of eight microsatellites, called NASA’s Cyclone Global Navigation Satellite System mission, or CYGNSS, got a boost into Earth orbit aboard an Orbital ATK Pegasus XL rocket, deployed from an L-1011 aircraft. via NASA http://ift.tt/2gNzyLp
