IRIS will fly in a polar orbit, 660 kilometres above Earth’s surface, constantly facing the Sun. Its narrow field of view will be trained on just a small part of the chromosphere: about 1% of the Sun’s disk. First light is expected about three weeks after launch, with science data ...

Named after astrophysicist Eugene Parker, discoverer of what we now call the solar wind, the probe will actually touch the surface of the sun on a daring mission where temperatures will climb as high as 1,400 degrees Celsius (about 2,500 degrees Fahrenheit). As detailed at Skymania, the p...
