The first Codemill Digital skills meetup was launched by Katie Haskell, a Spacecraft Thermal Engineer, who over the last six years has worked on a whole range of missions, including: EarthCARE, Solar Orbiter, LISA Pathfinder, Biomass and PLATO.With the talk "Software and Spacecraft: Not Just for Computer Scientists", Katie introduced us to general principles behind spacecraft engineering, including an overview of different roles and uses of software in addition to challenges.
Spacecraft engineers also need to be computer scientists
Every smallest detail matters, for example, Gaia spacecraft has stability requirements of 14 micro arc seconds.
Various planets in the universe have been discovered due to funny wobble on another planet
After building a spacecraft, testing happens in a vacuum chamber to make sure the thermal model behaves the same and afterwards, simulations can be done by analysis.
