accelerative stress that the vehicle’s structure or payload can withstand. In manned spaceflight an acceleration about six times that of gravity is considered the maximum tolerable when thehuman bodyis positioned perpendicular to the acceleration force—i.e., with the head and heart at the same ...
The U.S. Space Force will host companies next week interested in designing, building and launching two new narrowband communications satellites on which the service expects to spend $2.4 billion. The satellites will be used to extend the service life of the Mobile User Objective System (MUOS),...
