Has anyone seen this. I am surprised a shuttle mission permitted this type of booster. From what I believed, safety concerns prevented most types of boosters.

There are several CubeSats being developed that will carry thrusters, for example Delfi-n3Xt http://delfispace.nl/index.php?option=com_content&view=category&layo...
The safety concerns you mention relate to satellites fitted with conventional rocket fuel motors.
The Delfi-n3Xt approach uses nitrogen as the propellant and there are other approaches that would also be safe to fly.

Trevor,
The key part is that it was a manned mission. The complexity of the safety paperwork, let alone the mission, jumps because of that. Pyrotechnics of any sort are always an issue, but much less when the mission only involves hardware.

So the bomb on board (the pressure bottle for the Nitrogen system) isn't hazardous? Try selling that to Manned flight safety folks.....
Alan and Joe are right.
