A number of interesting things have been happening the world of microsatellite.
First, Skybox Imaging, which built its first two 100-kg imaging satellites (which offer stills and video) , will contract the next 13 to Space Systems/Loral. It's interesting because SS/L has never built microsats. Will they bring in fresh ideas? Or will they try to build them the way they do large satellites (which will not end well)? Stay tuned!
Then Northrop Grumman delivered its modular MSV microsat bus to the government. What they don't say in their press release is that the mission has no approved payload, budget, or launch date... nothing against the smart folks t NG, I am sure they delivered quality, but with existing budgets and plans, what they delivered is a high-tech coffee table.
