The United States has for many decades had stealthy satellites. There are declassified documents going back to the early 1960s indicating efforts to develop satellites that either could not be tracked (possibly because they were launched covertly) or that pretended to be something else. But those efforts always ran… » 2/12/15 12:33pm 2/12/15 12:33pm

It's really important to keep in mind that this is not a proposal, it is an early concept study. This is essentially to see if something is feasible and what it could do. Ultimately this study will feed into other studies and scientist teams will have to decide if this is the best way to obtain data or if there are… » 2/11/15 1:55pm 2/11/15 1:55pm

There was an NSA history produced in the late 1990s about signals intelligence before the attack on Pearl Harbor. One thing that showed up in the sigint traffic was that a Japanese tanker was positioned to the northwest of Hawaii. However, this data was not processed until after the attack.

I cannot remember why, but I think she essentially tells him that a man in her… » 1/31/15 10:46am 1/31/15 10:46am

Marc Rayman, the mission principle investigator, was on The Space Show Monday and I asked him about landing on Ceres. He said it is not possible. Ceres' gravity is too high and the spacecraft would impact at too high a velocity. In addition, they have planetary protection requirements that forbid landing on Ceres.… » 1/28/15 2:23pm 1/28/15 2:23pm
