Abstract: Practice:
This guideline provides a procedure which specifies and documents consistent, useful, and welldefined coordinate system (or frame) definitions for spacecraft attitude control design and ... -
NACA-TR-665
Abstract: Factors derived from wing theory are presented. By means of these factors, the angle of zero lift, the lift-curve slope, the pitching moment, the aerodynamic-center position, and the induced drag of tapered wings with ... -
NASA-LLIS-1579
Abstract: Abstract:
Building was not properly decommissioned. GSFC did not have formal procedures for decommissioning and transfer of ownership of buildings and/or systems (includes utilities, pneumatics and ...Subject(s) : Facilities , -
NASA-LLIS-0931
Abstract: Description of Driving Event:
JSC employees fell out of their office chairs when they broke. One employee was injured; the other was not. These two events were several months apart.
