SpaceX Launches NASA's PACE Satellite To Study Earth's Oceans, Air and Climate

NASA's nearly $1 billion PACE mission launched atop a SpaceX Falcon 9 rocket early this morning, successfully making it to polar orbit -- a first for NASA since 1960. "When it's up and running, PACE will make key observations of Earth's atmosphere and climate and allow scientists to assess the healt...

These colors are determined by the interaction of sunlight with particles in seawater, such as the chlorophyll produced by photosynthetic plankton, the base of the marine food web. "This will significantly improve our ability to understand Earth's changing marine ecosystems, manage natural resources such as fisheries and identify harmful algal blooms." "Measuring polarization states of UV-to-shortwave light at various angles provides detailed information on the atmosphere and ocean, such as particle size and composition," NASA officials wrote in the mission description.
