It describes in detail the development of The Messenger spacecraft, a probe set for a six-year journey to the planet Mercury.. Metal Processing Co. Inc, worked with the Johns Hopkins University Applied Physics Laboratory, to supply the Feedthru Helices that make up the antenna array that transmits and receives the signals for any images taken. It also is how communication and recorded data is established between Earth and the satellite.
This part was also just recently used for the launch of the Parker Solar Probe to provide imaging and communications sent and received between Earth and the Probe.
