WASHINGTON, Nov. 30 — The space shuttle Atlantis is to launch on schedule Thursday for a mission to the International Space Station after being cleared by a review of all elements of the flight, NASA managers said Friday.
Both polar and mid-latitude LDB capabilities continue to be on-going operational elements of the flight program.
Different architectures are then compared by means of Fault-Tree Analysis, highlighting the contributions to the safety level of the main elements of the flight control system (control computers, servoactuators, antenna) and providing basic guidelines on the required redundancy level.
It is ∼11 for the former, meaning that the respective Kuhn length lk, which is the length of the statistical element of the random flight chain, amounts to 2.8 nm while it is ∼7 for atactic PMMA translating in lk = 1.8 nm [ 19].
Other chapters describe the harsh, high-risk elements of the space flight environment, while this chapter describes general habitability requirements and the mission factors (e.g., mission duration and distance from Earth) that affect elements of habitability such as privacy, proxemics, and mobility in microgravity, as well as psychological stressors.
These vortices not only determine the form of the induced flow field but also interact with each other and with elements of the physical structure of the flight vehicle.
Induced drag is caused by that element of the air deflected downward which is not vertical to the flight path but is tilted slightly rearward from it.
Ms. Hersman said "the heroism of the flight crew was a necessary, but not sufficient element".
