About These Blogs: The JPL Science & Technology Blogs are a way for our researchers and technical staff to give first-hand accounts of the activities that are going on at the Jet Propulsion Laboratory. A cross-section of our staff contribute posts about the tasks they are currently involved in for NASA and JPL. These blog posts are meant to discuss technical topics. Selected comments that are on-topic are published and are moderated.

For the Juno Telecom panel, I am currently focused on creating my thermal math model (TMM). This model will be used to predict the thermal performance of the hardware under various operating conditions. Initially, these predictions will help to plan the combined thermal balance and qualification test that is scheduled for the telecom panel in early 2010. We can use the model to determine whether our test setup is adequate and to help define what typical temperatures to expect during testing. ...Read More on 'Spacecraft Thermal Engineering'

Spacecraft Thermal Engineering

NASA flight projects are broken up into 5 phases, A-E. Phase A is Concept Development, Phase B is Preliminary Design, Phase C is Detailed Design, Phase D is Fabrication, Assembly, Test & Launch Operations, and Phase E is Operations & Sustainment.

My Cassini work that I mentioned in my previous entry falls under Phase E. I have recently been assigned to do some work on Juno which is in Phase D. The telecom panel is set for testing in early 2010, but before that can happen, a lot of preparation ...Read More on 'Spacecraft Thermal Engineering'
