You may have heard of the craft called DSCOVR, but what is it, exactly? Why is NASA working with SpaceX to launch this craft into orbit between our sun and the Earth? It'll serve as a warning beacon - that's what. DSCOVR stands for Deep Space Climate Observatory, and now that it's been launched into space (just last night), it'll allow much better lead time for NOAA's space weather alerts and forecasts. Geomagnetic storms is what this craft will be warning against - where, when, and how severe we'll be getting them.
