Kennedy Space Center Associate Director, Technical, Jennifer Kunz speaks at an event Sept. 27, 2021, announcing that Terran Orbital will locate its Commercial Spacecraft and Constellation Facility on NASA’s Kennedy Space Center in Florida. The new manufacturing facility will be built near the center’s Launch and Landing Facility, which is being managed and developed by Space Florida under a long-term agreement with NASA. Terran Orbital develops end-to-end satellite solutions as well as commercial spacecraft. The 660,000 square foot manufacturing facility will consist of ten automated and augmented hangers capable of producing thousands of different types of space vehicles and electro-mechanical devices per year. The project is expected to create about 2,100 new jobs, with a planned completion date in 2025. The announcement ceremony was held at Space Florida’s Space Life Sciences Lab in Exploration Park, Florida.

During the first year of NASA MESSENGER orbital mission, the spacecraft GRS instrument measured the elemental composition of Mercury surface materials. mong the most important discoveries from the GRS was the observation of higher abundances of the moderately volatile elements potassium, sodium, and chlorine than expected from previous scientific models and theories. Particularly high concentrations of these elements were observed at high northern latitudes, as illustrated in this potassium abundance map, which provides a view of the surface centered at 60° N latitude and 120° E longitude. This map was the first elemental map ever made of Mercury's surface and is to-date the only map to report absolute elemental concentrations, in comparison to element ratios. Prior to MESSENGER's arrival at Mercury, scientists expected that the planet would be depleted in moderately volatile elements, as is the case for our Moon. The unexpectedly high abundances observed with the GRS have forced a reevaluation of our understanding of the formation and evolution of Mercury. In addition, the K map provided the first evidence for distinct geochemical terranes on Mercury, as the high-potassium region was later found to also be distinct in its low Mg/Si, Ca/Si, S/Si, and high Na/Si and Cl/Si abundances.
