Scientists loaded three missions worth nearly $1.6 billion on a SpaceX Falcon 9 rocket for launch Wednesday, toward an orbit nearly a million miles from Earth, to measure the supersonic stream of charged particles emanating from the Sun.
One of the missions, from the National Oceanic and Atmospheric Administration (NOAA), will beam back real-time observations of the solar wind to provide advance warning of geomagnetic storms that could affect power grids, radio communications, GPS navigation, air travel, and satellite operations.
The other two missions come from NASA, with research objectives that include studying the boundary between the Solar System and interstellar space and observing the rarely seen outermost layer of our own planet's atmosphere.
