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.

Spacecraft Thermal Engineering

During the Juno Critical Design Review (CDR), a question was raised whether the power cycling of the TWTA (electronics box) on the Telecom Panel could adversely thermal cycle the other electronics boxes mounted around the TWTA. This action item was assigned to me to evaluate the expected thermal cycling affects could be expected during typical operations.

Using the Thermal Math Model (TMM) developed earlier, I set the model up for a transient case that would simulate a science pass expected ...Read More on 'Spacecraft Thermal Engineering'
