Space Telescope Optical-Mechanical Design/Analysis Assistant
Marshall Space Flight Center (MSFC) - Internship
Student will contribute to structural design of potential space telescope systems and analyze the dynamics responses of candidate telescope designs to vibratory input such as a reaction wheel assembly's vibration. Design modifications will be proposed and assessed to determine their effect on stability. Also, the student will likely perform high level stress analyses of the designs under consideration being subjected to launch loads. NASA MSFC is currently developing and analyzing designs for a potential future space telescope to find and characterize exoplanets. Such systems have a multitude of technical challenges such as: how to deploy in space a large-aperture mechanically/thermally-stable optically-precise telescopes; model and control the dynamic stability/jitter of large telescope systems to maintain milli-arc-second pointing stability and diffraction limited wavefront; model and characterize the thermal response of large telescope systems to changing slew and role attitude.

|Building Number/Name & Room Number||4487 / B105|
|Work Environment||Office Setting|
|Expected outcome:||Student will be expected to write a final report documenting analytical models created and analyses performed; prepare a project poster presentation; and if appropriate write one or more journal papers. Student is also expected to provide pro-active interaction with the team in efforts to evolve pertinent engineering/analytical tools and capabilities.|
|Student's special skills:||Ideal candidate has ability to design truss structures and analyze their dynamic response to vibrations and thermal loads. Our team makes extensive use of finite element software such as NASTRAN, PATRAN, FEMAP, ANSYS, Thermal Desktop, Solid Edge, Solid Works, etc. Experience with astronomical telescopes is desired but not required.|
